    FLEXIBLA BYGGNADER: Utformning av en förskola med en möjlig verksamhetsändring för framtida behov2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Society today has an increasing demand for environmentally and economically sustainable developments in order to create a sustainable society. Society’s growth in new construction is a big part of this, and by planning and building more sustainable buildings these requirements can be fulfilled. The development of flexible buildings, which can adapt to future needs of society, lead to a more efficient utilization and longevity of premises and generate more sustainable buildings.In Sweden, the municipalities are the country’s largest property developers and therefore have a significant responsibility to provide society with real estate and public buildings. In recent time we have seen a shift towards flexible public buildings and in particular preschools. With the current socio-economic climate and ageing population buildings like preschools need to be flexible to ensure they can cater for future demands of society.

    This degree project, within the Bachelor programme in Construction Engineering, has been carried out during 10 weeks on Tengbom Architects in Uppsala. The thesis deals with the subject of flexibility in buildings and includes a proposal for the design of a flexible building as a pre-school that in the future can be converted into a retirement home.

    European Materials Modelling Council2017In: Proceedings Of The 4Th World Congress On Integrated Computational Materials Engineering (Icme 2017) / [ed] Mason, P Fisher, CR Glamm, R Manuel, MV Schmitz, GJ Singh, AK Strachan, A, Springer Publishing Company, 2017, p. 79-92Conference paper (Refereed)
    Abstract [en]

    The aim of the European Materials Modelling Council (EMMC) is to establish current and forward looking complementary activities necessary to bring the field of materials modelling closer to the demands of manufacturers (both small and large enterprises) in Europe. The ultimate goal is that materials modelling and simulation will become an integral part of product life cycle management in European industry, thereby making a strong contribution to enhance innovation and competitiveness on a global level. Based on intensive efforts in the past two years within the EMMC, which included numerous consultation and networking actions with representatives of all stakeholders including Modellers, Software Owners, Translators and Manufacturers in Europe, the EMMC identified and proposed a set of underpinning and enabling actions to increase the industrial exploitation of materials modelling in Europe. EMMC will pursue the following overarching objectives in order to bridge the gap between academic innovation and industrial application: enhance the interaction and collaboration between all stakeholders engaged in different types of materials modelling, including modellers, software owners, translators and manufacturers, facilitate integrated materials modelling in Europe building on strong and coherent foundations, coordinate and support actors and mechanisms that enable rapid transfer of materials modelling from academic innovation to the end users and potential beneficiaries in industry, achieve greater awareness and uptake of materials modelling in industry, in particular SMEs, elaborate Roadmaps that (i) identify major obstacles to widening the use of materials modelling and (ii) elaborate strategies to overcome them.

    Bygglogistik i en regionstad: Köra hit eller köra bort?2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The work is being carried out with the construction company Arcona.The aims are to evaluate and make recommendations about theirbuilding logistics solution CSL. For now, CSL is only used forprojects in Stockholm. If a need for CSL occurs in Uppsala, it willalso be introduced there.The purpose of the study is to investigate how CSL works inStockholm, what good experiences and challenges identified by theusers in Stockholm. Another purpose is to identify which partfunctions of the logistics solution that are requested by futureusers in Uppsala.To find out how the solution works today on projects in Stockholm,three qualitative interviews have been conducted. To find out aboutthe expectations of subcontractors (UE) on a logistics solution inUppsala, a qualitative interview has been conducted with asubcontractor. All interviews were then encoded to find themes andsubcategories.The conclusion is that both the subcontractor and Arcona see bothpractical and financial gains in introducing CSL in Uppsala. The mainadvantage of CSL is that it is scalable and you can choose to insertonly the sub-functions that are needed on the current project. Aservice that both sees benefits and which can be recommended is alogistics coordinator who reviews the entire logistics at theworkplace and thereby more easily identifies and solves problems.

    Anläggning av traditionellt VA-schakt: En fallstudie i logistik och byggstyrning2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A growing issue in the construction industry is how production can become more

    efficient by using logistical solutions. Companies can minimize the cost of a project by

    reducing the time to perform the work.

    The purpose of this report was to examine the logistics related to pipe trenches for

    SIAAB. The report's focus has been on solving problems and planning that would

    facilitate the work of the project Vaksala-Lunda Etapp 3.

    The case study consists of interviews with SIAAB's employees and an observation

    where the progress of a traditional pipe trench has been documented using checklists.

    Questions to the report’s case study come from the theoretical part, which is based

    on literature on construction management and logistics in general. The observation

    lasted five weeks and the biggest time-consuming events that affected the pipe trench

    during this time, has received most attention. Last part of the report is a compilation

    of the authors' own thoughts and opinions.

    The production was difficult in this case because the earlier stages of the project were

    weak. The extent of SIAAB's planning could have been higher, but this was

    complicated when employees were tied to previous projects.

    Ekonomisk och teknisk uppföljning vid anläggningsprojekt: För möjlighet till bättre erfarenhetsåterföring2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Due to the obvious fact that one can never be hundred percent sure of what's hidden

    under the ground surface, construction work is naturally hard to project.

    However, many of the work methods are executed in the same way on various

    projects. The department of construction work at JM AB region öst describes a lack

    of follow-ups and feedback between the calculators and production managers.

    In this thesis we have studied the communication between these groups and also

    how they share experiences and knowledge. In order to get the full picture

    of the day-to-day operations we used three methods to gather information. Studying

    literature gave basic knowledge of theories about feedback, and the

    necessity of working with giving feedback. In order to understand the process of

    construction work we made several interviews, both structured and nstructured. A

    survey was made with the purpose of getting a feeling of the attitude from the staff

    towards the importance of working with feedback.

    The result of this work showed a clear lack of a structured way of giving feedback.

    The communication between the calculators and production managers is

    not satisfying. Especially in the early phases of a project. At the end of this report we

    give some suggestions on how the work with feedback could be improved.

    These suggestions focus on creating ways to easily be able to do follow-ups on the

    day-to-day work at the early stages of a project. There's much to gain

    from having "good feedback". For instance, small problems and obstacles could be

    avoided due to better planning. Giving and receiving feedback could also raise

    the feeling of being important among the staff.

    Effektivisering av materialleveranser: En undersökning av möjliga förbättringar för leveranser av våtrumsinredning på JM2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Logistics in the construction industry is a difficult and troubled area with great room for improvement. Planning, preparation, management and control over material flow have become increasingly important for a company in order to keep up with the competition and reduce their costs.

    The purpose of this thesis is to investigate and identify possible improvements in the supply management regarding the interior for the sanitary rooms at JM- constructions. To identify possible issues with the supply management three of JMs projects in Uppsala have been analyzed.

    The result presented in this report shows that there is problems with the current supply management, problems which can be solved by introducing a Construction Consolidation Centre.

    Furthermore recommendations are given to introduce a pilot project with a Construction Consolidation Centre including: washstand, mirror cabinet, shower screen and towel rack.

    När befintligt ska bli nytt: Optimering av ombyggnation i befintlig kontorslokal2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vid utformning av kontor är krav på arbetsmiljö, tillgänglighet, trivselfaktor och att kunna påvisa sitt varumärke i kontoret av vikt. För att kontoret ska bidra till ett positivt arbetsklimat och ett effektivt arbetssätt bör även utformningen anpassas till den specifika verksamhet som bedrivs. Ett kontor med attraktiv utformning och bra arbetsmiljö ökar organisationens attraktionskraft mot befintliga och framtida medarbetare.

    Rapporten behandlar krav och aspekter att beakta vid ombyggnation av kontor och planering av ny kontorstyp i existerande lokaler. Med ett befintligt kontor finns givna förhållanden som ska tas hänsyn till och därför sammanfattas fakta om tekniska- och social aspekter som är av vikt vid valet av kontorstyp. Tekniska aspekter är ljud, ljus, luft, temperatur, bärande byggnadsdelar, vatten och avlopp, brand och el. Sociala aspekter innefattar ergonomi, kulörval, medarbetarhälsa, digitalisering, estetik och inredning. Olika kontorstyper beskrivs och utformningskrav från lagar och branschföreskrifter presenteras.

    Utförd studie baseras på en fallstudie av Skanskas kontor i Uppsala där en behovsanalys utförs och ett förslag på aktivitetsbaserad kontorslösning presenteras.

    Leveransproblem: Ett problem vid strukturerad produktion2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    When building large buildings, such as compartment buildings, there is a number of deliveries arriving on the construction site daily. In order to receive these deliveries without disturbing the rest of the work going on JM often books a fixed unloading time. When doing that they can be prepared when the delivery arrives. Making sure there is a suitable unloading area, someone to meet the delivery and when needed proper machines, such as a tractor or a crane, to help unload bigger deliveries. The person receiving the delivery is supposed to make an acceptance control where they check the delivered goods making sure nothing has been damaged in transport and that they have received what they were supposed to receive. Also noting whether the delivery arrived on time or not.

     

    In 2010 JM introduced structured production as their take on lean, and thus working more effectively. Structured production at JM means that everyone in the company performs the same task in the same way according to a predetermined assembly instruction. It also includes a certain way to make time plans for the whole project as well as for the next 5 weeks. As for deliveries JM tries to order these as close to just in time as possible. That reduces keeping material in stock at the construction site and also handling this material more than necessary. Handling material in stock is a big source of accidents and takes time away from other work. However, it is very vulnerable to have essential supplies arrive to the construction site just when they are needed as a delay can ruin the whole timeline of the production.

     

    This report aims, through qualitative studies, to find out how widespread the problem of late deliveries is at JM'S three construction sites in Uppsala and what JM is able to do to avoid it.

     

    The study showed that if deliveries are delayed, it refers almost exclusively to 1-5h on the desired delivery date. Deliveries being delayed so that they do not arrive on the right day were very unusual. One of the questions in the interviews was also whether JM themselves could have a negative effect on deliveries arriving on time by making changes in their orders, but this seems to have no significance when changes are made only after approval by the supplier and that the vast majority of deliveries after all still arrives on the right day. It rather seems that some providers take the order of a fixed unloading time less seriously.

    Something that does not make things better is that the procedure for handling delayed deliveries varies a lot just between the three construction sites in Uppsala and also between supervisors on the same construction site. It is not even always the case that the supplier is notified that the delivery was late, and then they do not know that they need to improve. Most suppliers buy in the transport of a shipping company and order a fixed unloading time from them. The suppliers interviewed all said that they wanted to know if the delivery was late so that they can contact the shipping company.

    Utvecklingsanalys av installationssystems montering vid industriellt träbyggande: Värme, vatten, ventilation, el och avlopp2013Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The industrialized timber housing process is capable nowadays to build multi-storeyhouses since fairly new changes in the Swedish regulations where made after theadmission of the European Union in 1994.The industrialized process moves parts of the construction process into a highlyeffective factory where 3D-volumes of the building are prefabricated beforetransportation to the building site for assemble.The assembly process is relatively effective compared to the completion of thebuilding service system and this is therefore the main focus in this thesis. This thesisattends problems with completion of the building service system, and thereforedemarcates from other aspects, such as technical and economic aspects, of thebuilding service system.The degree of completion of the flats differs from completion of the connectivepassages, for example hallways, in a way that suggests a need for further investigation.This thesis includes analysis of the possibilities to increase the prefabricatedconnective passages, to the extent of containing building service systems.An increase of the prefabrication of the building service system has a greatdevelopment potential, even though some restraining factors need to be solvedbefore implementation.This thesis was made in collaboration with two of Sweden’s leading companies on themarket of multi-storey industrialized timber housing, Moelven ByggModul AB andLindbäcks Bygg AB.

    Från BIM-modell till logistik: Möjligheten att digitalisera materialflödet2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    When all the information for smart building materials orders can be extract from aBIM model it is possible for correct material to be delivered at the right time at theright place. If a flow of material is well planned it leads to a more efficient work on theconstruction site and reduced waste.Overall, the relationship between material supplier and contractor has receivedsurprisingly little attention in research. Especially considering the amount ofcontractor-supplier-relationship there is in each building project. In this bachelorthesis the possibility of using information from a BIM model to a digital material orderis investigated. Furthermore, the need and problems in the digitizing process of thematerial flow and its operators is studied. The results show that a digitalcommunication is possible but requiring a major change in the process of materialflow.

    Mervärden av BIM: En analys av implementering av BIM i byggproduktionen2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The past 60 years, many industries have developed exponentially regarding digitalisation and they have adapted to the technology quickly. However, the construction industry has a linear development and has almost remained unchanged over the past years. It is still common to use printed plans at construction sites and raise buildings based on 2D drawings even if there are detailed 3D models accessible. There are great opportunities for development of the construction industry, but not many companies have succeeded in maximizing the outcomes due to limitations of external factors. The use of Building Information Modeling (BIM) needs to be standardised in the construction industry, in all phases.

    The thesis aims to investigate the obtained benefits of implementing BIM at construction sites. The thesis presents the topics of the construction process and BIM, and it accounts the results of the study based on a qualitative analysis. The responses from the interviews have been interpreted and summarised into a result, which are also confirmed by a background research. The study resulted in many benefits from the implementation of BIM at construction sites. To summarise, the benefits are: better information management, clearer communication, more efficient planning, reduced costs and increased quality. The study also shows that each benefit, in turn, results in additional benefits.

    The conclusion is that, in order to gain from the benefits, companies must invest in competence and resources. It is also necessary to demand more from authorities in order to make digitalisation a standard in the construction industry. There are great opportunities for an automatised construction process in the future. Furthermore, it can be speculated whether this will also lead to robotisation of the industry, 3D printing of buildings and using AI to design buildings. The first step for the construction industry is to catch up with the other industries is to standardise the use of BIM throughout the construction process.

    Hållbar avfallshantering vid nybyggnation: En jämförelse mellan olika avfallssorteringsmetoder2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Idag eftersträvas i allmänhet en hög återvinningsgrad och framför allt reducerade mängder avfall. Detta är något som bör prioriteras inom bygg- och anläggningsbranschen på grund av de stora mängder avfall som byggsektorn genererar. För att minska mängden byggavfall och framför allt den andel som hamnar på deponi behöver insikten i det avfall som faktiskt genereras öka.

    I det här examensarbetet studeras avfallshanteringen på två nybyggnadsprojekt och hanteringens inverkan på miljö och projektens ekonomi. De båda projekten har vidtagit olika åtgärder för att påverka avfallshanteringen och sorteringen av det blandade avfallet. Rapportens syfte är att belysa hur olika metoder för sortering kan påverka byggavfallet och andelen som går till deponi samt hur detta kan medföra ökad insikt. Målet är att försöka urskilja det bästa tillvägagångssättet att hantera byggavfall och utifrån det skapa en referensram som kan användas vid framtida planering av byggprojekt.

    Undersökningen består i huvudsak av komparativa fallstudier där avfallsstatistik på två projekt jämförs före och efter utförd åtgärd. Vid sidan av detta undersöks även följderna av en hypotetisk fullständig sortering. Litteraturstudier, platsbesök och telefonintervjuer utförs med syfte att få bakgrundsfakta och aktuell information som kan relateras till avfallsstatistiken.

    Resultatet visar att en ökad sorteringsgrad och en minskning av det blandade avfallet medför en ökad deponiandel och därmed ökade fraktionskostnader för deponi. Sett till total fraktionskostnad går däremot kostnaden ner vid en ökad sorteringsgrad. När extern part används för sortering ökar totalkostnaden för avfallshanteringen samtidigt som det sker en ansvarsförskjutning. Ökade kostnader måste vidare sättas i relation till ökad insikt och andra miljövinster. Att därför utifrån undersökningen hävda att det finns en optimal lösning för sortering är inte möjligt då det finns för- och nackdelar med samtliga metoder som undersökts. Vad som däremot kan urskiljas är att en sortering så nära källan som möjligt är att föredra då det medför störst kunskap om avfallets fortsatta funktion i kretsloppet.

    NOLLDEPONI: - Utopi eller realistiskt mål?2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The construction industry is one of the main operators at the Swedish industrial

    market, which means that the industry also contributes with a large part of Sweden's

    environmental impact. The construction industry accounts for a third of the country's

    total waste. And today a normal project sends about 10 % of waste to landfill, but

    how should a project proceed in order to achieve zero landfill?

    The purpose of this thesis is to highlight the opportunities that exist in waste

    management in the construction of new buildings and how to prevent landfill. The

    goal is to summarize the results in a checklist to serve future projects.

    The study consists of a literature review in order to determine the current state of

    knowledge in landfill. Interviews with leading persons at two of Skanska's successful

    reference projects were held in order to capture their opinions and thoughts on zero

    landfill, and the factors that made their projects succesful. Interviews were also held

    with waste contractors from two of Sweden's major waste companies, in order to get

    a different angle on the landfill issue.

    The result shows that the issue of zero landfill is very complex and there are many

    factors involved. There is much to improve, but those interviewed believe it is

    possible to achieve zero landfill, through:

    • Commitment in leadership

    • Careful selection of materials

    • Engage waste contractor early

    The question remains whether zero landfill is what benefits the environment most or

    not.

    Överlämnandet inom byggarbetsmiljösamordning: Riktlinjer och konsekvenser2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The concept of building work environment co- ordinator is a relatively new concept that has its origin in the amendment to the Working Environment Act which came into force on 1 January 2009. The terms; building work environment co-ordinator appointed for planning and design and building work environment co-ordinator for the execution of building or civil engineering work ushered in the industry. Once these disciplines complement one another, you can achieve a smooth handover to ensure a good and healthy working environment.

    In this thesis, we study a company in Uppsala and their operations and handover by interviewing the relevant staff in question. The result shows that there are currently no present guidelines for how and when the handover should take place, it is up to each individual to provide themselves with the relevant information.

    If the handover of the work environment would occur to the extent it should it would lead to minimized proportions of unforeseen risks and events that may occur during the production phase, which ultimately leads to a better and healthier working environment.

    Byggnadsintegrerade solcellssystem: Solceller som byggnadsmaterial2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to identify the building integrated photovoltaic solutions available in the market with respect to general pros and cons of different systems and a technical description of there attachment system. Investigate and provide examples of various building integrated photovoltaic solutions in Sweden and describe the experiences and results of these projects.

    The methods used to obtain relevant information are interviews with individuals involved in significant projects and a thorough search of different solutions from solar suppliers.

    The conclusion is that solar energy is needed for a sustainable society. There are endless opportunities regarding BIPV, with many companies with different products and individual solutions. But so far it’s not so customary in Sweden. Solar installations have until today not been able to be economically viable without subsidies from the state. But with declining prices for solar modules and rising energy price, a solar installation becomes more economically viable.

    Masshantering av schaktmassor: en jämförelse mellan traditionell masshantering och GPS-styrd masshantering i realtid2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this report is to analyze the advantages of using programme software to monitor masshauling instead of using the conventional method. A comparsion between different programs will also be conducted in an attempt to determine the most affordable. This report is written for NCC Construction AB to help them choose a software most fitting for future projects.The report is based upon literature such as information taken from the developers website, existing reports with similar context, interviews with sellers of the software and interviews with people working in the building sector.The result of this report shows that there are several advantages with investing in a software that helps the management of a project and that it is something that should be taken under consideration instead of the existing method. Topcon is a clear favorite following the inquiries comparisons as done, when they deliver a complete system and not only a supplement to the current approach. Scanlaser are just in the beginning of its development, and is so far only out with an early version of the software, while Topcon has been brought further in development and therefore has more features in the program. To utilize Topcon we fully recommend that the device HT-30 is used.

    Hand- och armvibrationer i byggbranschen: En studie av vilka faktorer som bidrar till uppkomsten av vibrationsskador2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    At today's construction sites, most of the work is carried out using hand-held and or hand-operated machines that create vibrations. Work with hand-held vibrating machines can result in damage to vessels, nerves and muscles, sometimes even on the skeleton, during continuous work. The effects of vibration damage can be powerful and in order to prevent these, work with vibrations needs to be considered and checked.

    The purpose of this thesis is to identify which factors contribute to the fact that vibration-induced injuries are so common at the construction sites today, despite the knowledge about the serious symptoms of the injury. By studying working methods, attitudes and behaviors and how the injury is prevented today, it is examined whether it is possible to reduce the occur-rence of vibration-induced injuries. The research begins with a literature study to obtain knowledge about vibration diseases and associated symptoms, as well as about the facilities and working methods that exist today to reduce vibrations at the construction sites. Further-more, a survey is conducted on how Skanska AB works with vibrations and interviews at some of Skanska Sverige AB's projects to clarify how the work against vibration injuries looks like in practice.

    The result of the thesis shows that work with reducing vibration is given some priority, but that it can be further improved. The employees have knowledge of the injury, but not enough to make demands on how developments can be made in the working environment. The working methods used are not optimal and there is resistance to the methods developed to reduce work with vibrations. During the interviews it emerges that many methods are mentioned in theory but that they are rarely used in practice. There are also deficiencies in the communica-tion between the different occupational groups regarding who is responsible for reducing the work with vibrating tools.

    The construction industry is developing in the work with reducing vibration, but there are also many parts of the industry that make the prevention work more difficult. The result shows signs of this and lack of time proves to be a great reason why the work with reducing vibrations is not prioritized. At the end of the report there are some recommendations given for further stud-ies to improve the preventive work. For instance, continued studies are recommended on how the difficulty with lack of time can be reduced and on how methods for reducing vibration can be more adaptable in practice.

    En jämförelse mellan TLS och UAV-fotogrammetri: Inmätning av hårdgjorda ytor2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    At present day there are several different methods for measuring of paved surfaces.

    The most common methods today are measuring with a total station, the Global

    Navigation Satellite System (GNSS) and terrestrial laser scanning (TLS). Recently the

    development of unmanned aerial vehicles, known as drones, has increased

    exponentially and today there are several ways of using drones for measuring surfaces

    by photographing and laser scanning.

    This thesis contains a comparison between the methods terrestrial laser scanning

    (TLS), and unmanned aerial vehicle photogrammetry (UAV). The measurements have

    been applied on two different test surfaces, one of asphalt and one of gravel. The

    purpose of the comparison is to investigate whether the airborne photogrammetry is

    equivalent accurate in its height levels as the terrestrial laser scanning. For the

    comparison to be more extensive, these two methods have not only been compared

    in precision but also in the areas of ease of use and economy.

    The precision was analyzed by comparing the height levels in randomly placed control

    points on the test surfaces. This has been made possible by the creation of terrain

    models of test surfaces in the software Geo where a surface scan of the models have

    been implemented. With the help of surface control the height deviations in the

    control points have been calculated and from these deviations the precision of the

    airborne photogrammetry has been evaluated. The ease of use has been analyzed

    based on observations made and information gathered from experienced consultants

    for each technology. For the economic aspect the costs for each measurement

    method has been presented to get an overall picture of each measurement method

    costs.

    The work has been carried out on behalf of the consulting firm Bjerking AB. The goal

    is to be able to provide Bjerking with a recommendation for which technology is best

    suited for measuring of paved surfaces.

    The results of the survey show that the UAV varies by a mean of 11 mm on the

    surface of gravel and 2 mm on the surface of the asphalt. The final recommendation

    given is that the UAV is preferred for measurement of asphalt roads, because since

    the precision is equivalent to TLS, the method is safe

    iPad på en byggarbetsplats: Det effektiva och papperslösa sättet att arbeta på2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Quality assurance of construction projects and create effective ways of working, is intoday's pressed position, major objectives for building contractor companies. This thesis is an attempt to see if it is possible to achieve these goals with the new modern tool iPad.

    The author of this thesis has during the latter half of his one year practice work in Uppsala for the Swedish building construction company NCC Construction Sverige AB, conducted a study on the possibility of using the iPad on an construction site. This has been done with active field studies in which applications have been tested and also the supervisors receptive. The usability of the iPad has always been in focus since it is important that the applications are easy to use and easy to learn.

    The results of the work, as presented in this report, points at opportunities in efficiency if the iPad is introduced and used on construction site. There are many useful applications for the iPad, and with a system that can handle the synchronization between the iPad and the computer, the workflow will be streamlined significantly.

    Professionell garantihantering: Ett arbete inom byggnadsbranschen2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A business is always dependent on its customers. It is therefore important to ensurethat customers are satisfied with the product and the warranty included.The study was conducted in cooperation with the building contacting companySkanska Sweden. The aim is to use interviews to collect and process experiences in order to answer the question: How should the recovery process in the construction industry be performed to ensure a professional handling of warranty? The results have shaped my conclusions and I have turned them into a proposal that companies in the industry can benefit from. The study indicates that the industry is not geared for a five year warranty, which was introduced in 2004 and 2006. This is manifested by difficulties to prioritize the management of guarantees, with long lead times and customer-, and employee dissatisfaction as a result. Achieving a professional management means to adapt the company to a longer warranty. It means taking responsibility, prioritizing and investing in the organization and effective computer systems. The investment will help to create a stronger brand and increase the profitability for the company. The results suggest that companies should set aside time for staff and implement an aftermarket organization that supports and relieves the staff. An important aspect is that a financial liability for the guarantees should be anchored in the production staff. Otherwise it can result in a reduced quality due to lack of responsibility during the construction process, leading to increased warranty costs. The industry is also in great need of accessible craftsmen that quickly can fix errors. The problem is that most craftsmen today are occupied in the new construction projects, it creates longer lead times for the process. The craftsmen must also be suitable for a job in the aftermarket. The way of handling the issues in the industry are not uniform and are often outdated. Therefore a need exists for a modern and computerized case management system, it would improve the situation for both staff and customers. Companies can also use an evaluation system to rate their partners on how they acted during the warranty period. The information can be valuable for future collaborations. Knowing that a classification is performed can also increase the corporate accountability. Contracts in the future can be added a clause to encourage responsibility for the work during the warranty period. The clause requires a meeting where the contractors, among other things, can agree on a case management system to use. But most important is to pay attention to the work during the warranty period, which must be improved.

    HANTERING AV JORDMASSOR VID ANLÄGGNINGSARBETEN: En ekonomi- och miljöanalys2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study was carried out on behalf of Peab Construction, a contractor in Uppsala. Peab’s, and hence the authors’ intention was to investigate the handling of excavated material during construction work. A construction site was investigated as a case study, in order to find better ways to minimise the use of uneconomical procedures and environmental impact. The given project was a water and drainage pipe in an area around Uppsala. This study was carried out mainly by using documentation from the project specifications. In addition, considerable information was also acquired from experts at Peab by means of several interviews.

    The investigation was carried out by analyzing and studying the working time and fuel consumption of different machines used in the project. The total cost of the management and the total fuel consumption were calculated for each soil type handling method. The conclusion is that an optimal solution would be to spread the excavated material in the surroundings of the construction site in order to lower costs and attain the smallest possible environmental impact. This conclusion also gives Peab Construction, and other contactors, an estimated value of what they could save financially on similar projects. In addition, they will also be able to supervise in a better way, and limit their environmental impact.

    PLATTA TAK: En utredning om vad som bör beaktas vid projektering och utförande2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Flat roofs have been common for many decades. They were first build in dry and mountainous areas, then they were spread in the entire world. Today flat roofs are present in all type of buildings. In Sweden they are mostly used in larger houses like shopping malls, industrial buildings and apartment blocks. Flat roofs are very exposed for the elements and since the roof is flat water can easily be stationary. The water will then start drain through slots and the construction will be destroyed. The purpose of this study is to evaluate flat roof construction of today in consideration to leakage and moisture problems. Are today's constructions any good? Are today´s building materials the ones that should be used in tomorrow's constructions? Focus has also been made to evaluate new possible solutions for the construction were prefabricated elements is one.The most leaks can be found were bushings has been made that don’t follow the acquis available. The quality of the construction is good, but there are other circumstances that creates the problems. It’s of great importance to keep water away from the construction under the production time. One way to do that is by making a weather protection. Because of the high cost it is not very common.Prefabricated roof elements have a lot of advantages. Since they are built in controlled indoor conditions building moisture is not a problem. When the roof elements come to the construction site they are already finished and the assembling will go fast and the house will be densely directly. There are some aspects that need further investigations such as transportation of the roof elements.

    Abstract [en]

    The construction industry is constantly evolving with new products and building technical solutions. The construction industry organization jointly developed regulations known as standard contracts, or general regulations, which includes ten chapters. The standard contracts describe what the constructor industry should relate to in terms of performance and responsibility. When the standard contracts were negotiated about between the various parties in the industry some sections were developed through compromises. It is mainly in these sections misunderstandings, interpretations differences and conflicts occur.

    This report investigates in which sections conflicts commonly occur, what the consequences are and how the generally perception of the standard contracts is in the industry. The report also suggests solutions and improvements to the standard contracts.

    Eleven basic questions based on the generally perceptions of the standard contracts and the first six chapters of the standard contracts have been developed to clarify where disputes and misunderstandings may occur. The remaining four chapters have been deliberately excluded to limit the scope of this report. The content of the report is mainly based of twenty interviews with contractors and clients.

    The study shows that the perception of the standard contracts is positive and serves as a good tool to know what to relate to. The standard contracts should however adapt more to today's technological society. The study also presents suggestions on methods and advices that can be used to facilitate communication in the construction industry.

    This thesis in the Bachelor of Science in Construction Engineering at Uppsala University has carried out for ten weeks at a property company Klövern in Kista.

    Kvalitetssäkring med digitala hjälpmedel: En studie om BIM 360 Field2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    For a long time, the construction industry has lagged behind in the field of digitalization. It is about time for the industry to find new tools to be able to deliver a higher standard of quality assurance. This report is concerned with the application BIM 360 Field, which is a cloud based IT-tool and can be used by anyone on the construction site. The application has multiple areas of usage, including deviation handling, self-monitoring, QR-code, inspection and completion plans.The purpose of the study is to examine how effective BIM 360 Field is compared to the industry’s traditional way of handling deviations. This degree project is written in cooperation with Skanska Sverige AB and the project “J-huset” in Uppsala. The purpose is further to examine if BIM 360 Field can be applied and used for the inspection of “J-huset”.The study has been carried out through interviews with the production management on various projects. Interviews, as well as an introduction to the application, have been carried out with proficient staff from Skanska. A field study has been undertaken on the “J-huset” in Uppsala for the purpose of gaining a personal opinion as well as knowledge of the application.The result gained from the study is that BIM 360 Field has great potential for saving time during the construction process. From the interviews with production management, who used BIM 360 Field during production, some issues have been identified with the application.The conclusion in this study is that the BIM 360 Field is applicable to the “J-Huset” in Uppsala. The program is user friendly and has great potential to streamline work on quality assurance in production. In order to achieve a successful result, it is recommended to use the program at an early stage and throughout the production

    Abstract [en]

    Fall accidents are a big problem in the construction industry today and stand forapproximately 23% of all accidents. Skanska is a construction company that has avision toachieve zero accidents. Eliminating fall accidents is one step on the way towards theirvision. The state of Skanskas fall safety has been analyzed in this thesis to show whichimprovements are possible in fall safety.A literature study has been performed in which Arbetsmiljöverkets (The Swedishwork environment authority’s) laws and rules, together with Skanskas own rules havebeen studied. The conclusion of the literature study is that Skanskas own rules wouldbe sufficient to meet the goal. If those rules were followed then all the lawrequirements would be fulfilled with good margin, and good fall safety would beachieved.Construction site visits have been made, participation to safety rounds undertaken,and safety round protocols collected in order to analyze the state of Skanskas siteswhen it comes to fall safety. The results showed that Skanskas construction siteskeep a very high standard when it comes to fall safety, but there are improvementsthat could be made regarding the general order on the sites, and also by properlymarking the covering of holes.Interviews with site managers, production leaders, safety representatives, Skanskasconstruction workers, subcontractor supervisors, a health and safety engineer and ahealth and safety manager from Skanska England were undertaken in order to get anidea about what flaws might exist today within fall safety, and what can be done toimprove the fall safety.The results from these interviews showed that improvements on how people usepersonal fall safety equipment must be done, and that the major cause that so manyfall accidents occur is a lack in safety behavior by the construction workers. Increasedsafety awareness and changes in personal behavior are required to reach the vision ofzero workplace accidents.

    Abstract [en]

    Ask any constructional worker and there is a high probability that this person knows a colleague with pain or other disorders caused by working with power tools.

    According to the Swedish Work Environment Authority 71 percent of the Swedish constructional workers is exposed to vibrations at least 25 percent of the working hours. Despite this, the number of reported occupational sicknesses caused by vibrations is as low as 1, 4 percent.

    JM Ltd. is one of the largest constructional companies in Sweden. Their main business is new housing and development of residential areas. God quality and low impact on the environment is a part of great importance in the company’s long-term goals. To achieve this, and to ensure an effective production, the activities have gradually been organized according to Lean production. In the year of 2010 the producing part of the company began to use methods originating from Lean such as process orientation and standardization of work procedures. JM calls this Structured production.

    The purpose of this thesis is to investigate how working according to Lean when producing apartment buildings interacts with a safe working environment. The goal is to investigate and identify problematic operations during the assembly of semi-prefabricated, non-bearing walls so-called perimeter walls.

    The method used is a time study conducted in spring of 2014 on construction sites in Stockholm. The exposure to vibrations from power tools on construction workers, when working according to the installation instructions applicable at JM’s building projects was examined.

    The study revealed that the action value determined by the Swedish Work Environment Authority was exceeded when installing perimeter walls according to the installation instructions.

    The conclusion is to extend measurements and medical surveillance of exposed operations and personnel. A package of equipment and materials to be used when installing perimeter walls is presented along with possible methodological improvements of the installation instructions.

    Kunskap och erfarenhetsåterföring inom byggföretag: Studie baserad på Åhlin & Ekeroth Byggnads AB2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Repeated mistakes within the same company is a frequent occurrence in theconstruction business. The cost for repeated mistakes within construction projectsis stated to be 10-30 percent of the project’s total revenue. Constructioncompanies usually divide their work into several projects where the employeeswork in parallel project groups. This leads to lack of knowledge and return ofexperience. Due to the lack of time often experienced in the construction business,the termination of projects is not handled properly. Conclusion meetings are not apart of the routine which in turn leaves knowledge and return of experienceunheeded.In this report, a study of Åhlin & Ekeroth Byggnads AB has been performed. Thegoal was to create an understanding of how the company handles the processregarding termination of projects, knowledge and return of experience. Theunderstanding was created through interviews which together with theoreticalbackground lead to an assessment and a discussion of recommendations for Åhlin& Ekeeroth Byggnads AB. Since Åhlin & Ekeroth Byggnads AB is a medium-sizedcompany in Sweden, our studies’ recommendations can be practiced also by othercompanies.In this study we reached the conclusion that there are elaborate documents forhow the termination of projects should be handled and performed within Åhlin &Ekeroth Byggnads AB. These documents also contain usage of knowledge andreturn of experience as well as when and how this should happen. The complex ofproblem within the construction company is that one does not follow thedocumented plan when terminating a project which leads to a suffering return ofknowledge and experience. The recommendations given in this study explain howto create a common structure for handling termination of projects. This in order tocreate participation among the employees which in turn contributes to increasedengagement and routine based terminations of projects. Further, the companyshould create a searchable database containing simple and systematic documents.It is also important to set aside time for knowledge and return of experience. Inconclusion, it is important to keep the employees motivated to prioritize knowledgeand return of experience – something that is created by participation and simple,systematic documents.

    Bygg gärna, men inte här!: Ledtider och kostnader i Detaljplaneprocessen2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis examines the Swedish detailed planning process from a time and money perspective, and also points out the deficiencies of the process. The detailed planning process currently receives much criticism from both the society and the industry. It is usually considered as a brake in the production of new housing in Sweden.

    A few of the municipalities’ administration time in the planning process in Stockholm was compared and analyzed and it was concluded that the average process takes between 30-60 months. However if a zoning plan is appealed the process extends usually between 4 to 12 months. In Stockholm County, a fourth of all the zoning plans are appealed, but only 1.3% of these leads to repealing of the plan. This number questions to some extent the democracy in today’s society, how many of the citizens’ complaints are actually accepted since that number also include complaints from authorities like the county administrative board.

    To obtain an understanding of the developer’s cost of the planning process a couple of housing projects in the municipality of Stockholm and Solna were examined. The investigation revealed that the cost may vary anywhere between 650,000 up to 6.5 million SEK. The cost of the zoning plan proved to be highly correlated with the time spent.

    The recommendation from our side is to increase the exchange of information between all parties, including the party concerned, leading to benefits of the process as a whole. Less public opposition leads to a smoother process, while increasing the cooperation between the municipality and the developer do as well.

    Vägen mot en integration av BIM och Internet of Things: En modell över fördelar och förutsättningar vid användning av Internet of Things i BIM2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis considers the integration of BIM and IoT in the building process of offices. The thesis is hopefully going to create knowledge about BIM and IoT and describe what needs to be done to carry out an integration.The planning of offices today consists of the use of BIM and a lot of smart solutions. But what are the benefits from an integration of BIM and Internet of Things and how can this be used throughout the building process? New and smart solutions are invented all the time and although not all are possible to use in everyday offices, some can already be of great use. For the future there is a great need for smart and sustainable solutions that helps to conserve energy but at the same time are economically sustainable. This needs to become a part of our everyday to help conquer one of our times biggest challenges, the environmental issue.

    This thesis highlights the advantages, disadvantages and requirements of an integration of BIM and IoT. It concerns the technology behind IoT and what the future has to offer.The result of the written thesis is a model that describes how an integration of BIM and IoT can be carried out during the different stages of the building process. The model is going to work like a cycle where information from sensors constantly flows to the BIM model during the entire building process. Information and experiences gained from the different stages of the building process can be used

    to evaluate the construction and its different systems and the experience gained is used in the next project.An integration will be hard to do on a big scale due to different factors. The technology is here but the pathway and standards for it are not.

    Sambandet mellan produktionsplanering och arbetsmiljö: En studie hur produktionsplaneringen kan bli bättre med avseende på arbetsmiljö2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The work aims to investigate how site managers are planning projects, and how this is experienced by the craftsmen regarding work environment with a psychosocial and physical aspect and construction management. Recommendations are made to improve construction management based on the results from the interviews. The work is being carried out as there is a greater focus on work environment in the workplaces today. A way to facilitate the additional administrative work that arises with this focus is to improve production planning. Placing a greater focus and more time before production has started can be beneficial to the construction project. In the report ten interviews are made from five different projects where we interview a site manager and a craftsman on each project. Among the site managers, many felt that there was a high workload due to lack of resources or additional work. All interviewees agree unanimously that one should have a craftsman or safety representative at an earlier stage during the production planning. Several site managers are requesting a clearer structure in the organization at an earlier stage in production planning. Craftsmen request official meetings with a clearer structure on the information provided.

    BIM i produktion: En undersökning om hur BIM kan implementeras  i produktion2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The object of this report is to investigate how to implement BIM into the production part of the construction industry. How NCC should act to make the transformation as smooth and easy as possible. BIM, Building Information Modelling, is a way of working where you gather all information in one place. All disciplines work in a 3Dmodel and have information about their component in that model. For example, you can create a specific wall with its different layers, that will make it easier to calculate offers from subcontractors and also make the daily work with other orders easier if you know what the wall is build of. You can also use the model for collision controles. This make everything more efficient and make it easier to collaborate between different disciplines.By interviewing people from the industry, mainly from the production, we found that there already are softwares on the market that NCC are using that is easy to use even if you haven't worked a lot with digital tools before. The problem is how to spread the information about these softwares so that more projects can use them. Another difficulty is how to get the craftsmen to use these softwares. The people we interviewed thought that the lack of interest for digital tools, and the older generation, is the main reason why the implementation will be challenging. Our conclusion is that NCC need to find a systematic way to educate their employees in the digital tools that they are using. They need to get better to spread the word about those digital tools within the company so that their employees understand how much they can help and will start to use them. The craftsmen should use the tools to help visualize what they are building and the on-site manager should have a software with more features.

    Konsekvensen av sena ändringar i byggproduktionen: En utredning av ändrings-PM under produktionen2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis project examines changes to building documents during the product development in the construction process, which is referred as revision memos in this report. The study is made in cooperation with Serneke and is therefore limited to project within this company. Furthermore, the information in this study is based on relevant literature as well as interviews, a poll and material from three of Serneke´s projects.

    The results show that the examined projects have exceeded the estimated design cost due to changes made during production. By investigating the revision memos, the conclusion was that performing construction, commercial projects and rebuilding projects generate more revision memos as well as the architect and constructor had the greatest number and most expensive revision memos. It also appears that the number of revision memos of other disciplines varies between projects. Furthermore, the design process seems to generate many mistakes that appear in the production, which means that an improved design process with experience feedback and collision control should detect mistakes at an earlier stage.

    Recommendation for future projects is to make use of the contractors knowledge of production early in the design stage, to use experience feedback and collision control, to introduce a date for last additions, to use Swedish standard when establishing revision memos and to not execute changes before a revision memo is published.

    In conclusion of this project follows a few recommendations for continued investigation of this field of study.

    Granskning av Solibri Model Checker - En Svenskanpassning: Jämförelse av två egenkontrollsystem2013Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The building industry are currently going through a huge alteration. The introduction of BIM (Building Information Modeling). Which also implements a lot of new ways of solving problems that building modeling can cause. This report is written for Uppsala University in cooperation with Temagruppen in Uppsala. However, it contains a comparison between two different systems that checks building models. Temagruppen invested in a new Swedish adaptation of a software called Solibri Model Checker. This Software controlling the availability in building models, it also introduces a new way of interaction between different instances during a building project. The definition of the report is availability in public buildings. A building model has been designed in Revit, then imported to Solibri Model Checker who controls the availability and creates a report of certain design fault. Interviews are given to get a look into how the work with availability controls currently works at Temagurppuen. This results in a discussion of benefits and disadvantages

    of the two different methods. The result finally shows that certain work can be more effectively done with Solibri Model Checker. But availability contains more than just disabled impairment. Visual- and cognitive impairment can’t still be controlled by just a computer software.

    Att planera bort störningar: Verktyg för smartare tidplanering inom grundläggning2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta är ett examensarbete skrivet i samarbete med Skanska Grundläggning Syd med syftet att utreda hur deras planeringsarbete ser ut idag och vad som eventuellt kan göras bättre.

    Ett tidigare examensarbete har skrivits på avdelningen som undersökte produktiviteten ute på arbetsplatserna. I detta arbete var slutsatsen att produktionen stod still ca 40 % av arbetsdagen på grund av problem med maskiner eller leveranser, onödiga förflyttningar och att andra entreprenörer stod i vägen med mera. Målet med mitt arbete har varit att bygga vidare på detta och se om bättre planering kan bidra till att minska olika typer av produktionsstörningar.

    Underlaget till rapporten består av observationsstudier där arbetet på tre olika arbetsplatser följts samt av intervjuer med arbetsledare och andra personer som varit delaktiga i planeringsprocessen. Där noterades att en noggrann planering inte alltid görs, trots att det ofta finns krav på detta från beställaren. Tecken på detta syns bland annat på tidplanen och arbetsplatsdispositionsplanen som ofta är alltför odetaljerade. Resultatet blir att de kanske inte stämmer helt och är mycket svåra att följa upp. En effekt blir också att det är väldigt svårt att kommunicera hur stort utrymme entreprenören behöver och till när, vilket naturligtvis lätt leder till att de andra entreprenörerna på plats står i vägen eller inte har hunnit förbereda marken. Det uppstår också svårigheter hos leverantören av pålarna om inte projektet kan ge en tillräcklig framförhållning, vilket självklart ger problem med leveranser.

    De slutsatser som har dragits av undersökningarna är att arbetena behöver planeras mer noggrant och på ett sätt som går att kommunicera till andra. En rekommendation är att tidplanen görs visuellt genom markera etapper på en pålplan. En sådan visuell tidplan kan också användas som underlag för att diskutera dispositionen av arbetsytan och vilka ytor man behöver tillgång till. Utöver detta föreslås att en uppföljning görs av produktiviteten varje dag. En tredje rekommendation är att en checklista för planeringsstadiet tas fram, så att man inte behöver upprepa samma misstag som gjorts tidigare. När planeringen görs noggrant, erfarenheter sparas och kommunikationen på arbetsplatsen är öppen och tydlig så finns stora möjligheter till en trevligare arbetsmiljö och ett lönsamt projekt för alla inblandade.

    Materialhantering på byggarbetsplatsen: En fördjupning om inbärning2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The logistic management in the construction industry has for a long time been an unchanged process, but the industry is now starting to understand that effective delivery management, both to and on the workplace, will lead to positive effects on the economy and the working environment. It is uncertain, however, how large the economic effects are.

    This study is written in collaboration with Skanska and aims to investigate the economic and time saving advantages of using carrying services. The use of carrying services is a logistic solution where the transportation of material from delivery to the point of installation on the construction site is carried out by a third party. The foremost advantage of the service is that the construction workers do not have to disrupt their work to take care of deliveries and unload materials, and that the transportation of material can be done at a lower cost.

    A large amount of time has been invested in interviews with people who work with management of construction projects. The interviews were focused on the service carrying and logistics in general. Observations of work sites have been done in order to increase the understanding of how the configuration of the work space affects the time it takes to carry materials into buildings.

    The results of the study show that there is optimism concerning a future use of the service, but that there are some aspects that still need to be fine-tuned. There needs to be a more extensive exchange of knowledge, and control documents need to be formed. The results also show that it is difficult to specify the exact costs of current logistic management, and therefore the economic advantages of carrying services cannot be determined within the scope of this study.

    Förstärkt verklighet i byggbranschen: En undersökning av AR som metod för att undvika samordningsbrister och byggfel2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    At present, augmented reality (AR) isn’t used to any significant degree in Sweden. However, the technology is considered as the next step in digitizing the constructionprocess. The development of AR has come a long way over the years but has not until recently begun to take shape as a tool to rely on. The purpose of the study has been to investigate today's AR technology and then identify its uses in the construction industry. The focus has been on investigating the possibilities of an application to prevent construction errors and coordination flaws, but also to see if the technology is useful in other ways in the construction process. The method used was based on a summary of technical reports of AR technology in a literature study. Applications and future possibilities with the technology have been described while the tracking systems and devices behind the applications have been studied. Interviews were conducted with staff at different positions at the workplace, working closely with the design and production. Based on these interviews, uses, advantages, shortcomings and development opportunities with AR to reduce construction errors have been established. The report points out that there are sufficiently good positioning systems currently available for AR to be applied to a construction site and that these are constantlybeing developed. However, further development of AR applications is required to enable them to meet the functions needed to overcome construction errors and coordination flaws. Even the devices that are most advantageous for the construction industry need more work to increase performance and eliminate possible health risks such as dizziness and nausea in constant use. At present, AR can be applied for simpler tasks such as illustrating models during meetings or for sale.

    Material och uppbyggnad vid renovering av reveterade skiftesverk: En analys ur fuktsynpunkt2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Boule houses are a type of timber construction. The houses have been used since the middle ages in Sweden and some of them still remain today. A rendered boule house wall is open for diffusion and able to buffer moisture. Rendered boule houses are a cultural heritage. The expression if the facades should therefore be preserved and the thickness of the wall should not be changed. When rendered boule houses are renovated the construction of the wall is sometime changed and the lime render is partly replaced with insulation. This report investigates the prefered materials and construction techniques to reduce the moisture in the wall. The goal is to contribute the knowledge base regarding moisture risks when renovating these walls.

     

    WUFI and Folos diagram were used to study 17 wall types. The program and the diagramm provided information about relative humidity, temperature and duration of critical periods for the chosen wall types. Wood fiber insulation with the ability to buffes moisture was compared to mineral wool that lacks this ability. Three different types of mortar were studied, namely; air hardened lime mortar, hydraulic lime mortar and lime-cement mortar. Four different construction types are included in the report. The first represent an original lime rendered boule house. The second is insulated without an air gap and the third includes an air gap. The fourth construction type has no air gap but an insulation board is placed between the mortar and the wooden pillar. The fourth wall type was only studied with the hydraulic lime mortar.

     

    Interviews and litterature studies were preformed to gain knowledge of what material and which constructions that are of interest to investigate. The amount of critical moisture hours for two different layers in the wall was presented. The layers were chosen where the wood is specially exposed. To clarify the result further chosen periods where studied. Finally, the result lead to a discussion regarding the mortar and the insulation’s ability to buffer moisture. The conclusions were that the lime-cement mortar led to more intense and longer critical moisture periods. It also seemed like an insulated pillar was better off than pillars in direct contact with the mortar.

    Störningsfritt byggande: Om störningar på tredje man från byggarbeten2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In recent years, a densification of Uppsala's city center has taken place. Construction works are now happening closer to existing buildings than before. This raises the question of how the construction industry interferes with those already living and working in the area more relevant than ever before.

    This degree project investigates the extent to which the construction of Gränby Entré affects Gränbystaden's customers. The disorders that affect most are investigated and recommendations for how Atrium Ljungberg should work with disturbances in the future is being developed.

    This was investigated through surveys with the visitors and interviews with key people in the project. A total of approximately 400 surveys were done, half of which was done in paper form in Gränbystaden's mall and half from a web-site marketed via Gränbystaden’s Facebook page.

    The disorders investigated are parking problems, noise, waste and dust, light, vibration, and closed or different routes. The result of the survey shows that parking problems and route changes are the disorders that are considered to affect the most. Then there will be rubbish and dust, then noise, light and last vibration.

    The survey has also examined how visitors would like to get information about the construction works. Here, the answers differ quite a bit between the web survey and the paper survey, but there’s a trend towards social media, but also a desire to get the information in paper form.

    The study has resulted in recommendations to Atrium Ljungberg on how the problems should be addressed in the future. I suggest that they should use social media in the future to inform about construction works and send out information by mail to the immediate area in case of major disturbances. They should review bicycle and walkways to and from the mall as well as create routines for cleaning around the construction site.

    Svensk Byggindustri och Critical Success Factors: En lokal diskussion kring kritiska moment vid implementering av BIM2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    BIM (Building Information Modeling) is an exponentially growing field within the construction industry, with no signs of slowing down. However, as the process continues to spread on both an international and national scale, issues with implementation inevitably arise due to many different factors, in this work identified as CSF (Critical Success Factors).

    The purpose of this work is therefore to examine these factors, as well as the term CSF itself, with regards to meaning and relevance. Based on previous studies the term CSF, as well as 14 factors, were established. To correlate these internationally described factors to the Swedish market, five interviews featuring people with experience of BIM in Sweden were conducted, after which similarities and patterns could be recognized.

    The core concepts continually established throughout the work was the value of mutual and shared understanding, as well as the importance of utilizing previously established knowledge within the construction industry. The report concludes that the identified factors as well as the term CSF are both valid and beneficial for future discussions and implementations of BIM

    Tillbudsrapportering inom JM: En analys av förbättringsarbetet2013Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The construction business is one of the most accident prone businesses in Sweden. In order to make it safer it’s vital that all employees of a company report all accidents and incidents that occur. This report intends through qualitative interviews, to analyze the knowledge and attitude towards incident reporting among the employees of the Swedish construction contractor JM.

    The goal of the thesis work is to hopefully contribute to an increase of employees’ awareness on those issues. This report also intends to analyze why not all of the occurring incidents are reported and which measures can be taken in order to increase the number of reported incidents.

    The study shows that the knowledge towards incidents and accidents is diverse among all employees. Many employees are having difficulties defining what incidents are to be reported and many craftsmen don’t know how and why they should report an incident. The major differences are on the one hand between craftsmen and white-collar workers, and on the other hand between senior employees and new recruits.

    In order to increase the number of reported incidents, JM can introduce incident report pads to be carried by their employees at all time. They can also continue educating their employees in why it’s important to report all incidents and how to complete a report.

    Förstärkning av betongkonstruktioner med kolfiber med avseende på olika brottstyper2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe.

    Energiåtgång under tillverkning och produktion av byggnadskomponenter2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This diploma work addresses the question of how much energy is spent whenmanufacturing the components of a building as well as of how much energy is used inthe production of a building. The object of the studies is BioCentrum at the SwedishUniversity of Agricultural Sciences in Ultuna just outside the city of Uppsala. The aimof the work was to investigate how much energy was consumed when manufacturingand production in relation to the management, how many years the production wasrepresented. It was also a study in how mature the construction industry is to answerhow much energy was consumed in manufacturing.In order to get these answers a question form was developed and sent to thesuppliers to BioCentrum. In this form they were to respond to the quantity suppliedto BioCentrum and the amount of energy was spent when manufacturing thecomponents. Unfortunately the response rate was very low and we instead had toseek information on the internet. This was done by using building productdeclarations. With a list of the quantities used in the building, received from NCC, theenergy was calculated.The result of this investigation shows that the construction industry needs a fewmore years to mature before they can fully respond to this. But with the values wegot from the suppliers and our own calculations, we concluded that the manufacturingand production represents 3.5 years of the management of the building. This wascompared with the projected energy consumption of 124 kWh/m2, year.
