    Kartläggning av arbetsledarens arbetsfördelning i byggproduktion: En undersökning av möjliga förbättringar inom yrkesrollen2017Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    Every company strives for maximum efficiency. The construction industry, which is complex while margins are small, makes efficiency an important issue. In the construction industry today,the high demand for production is to be delivering high quality projects as well as within certain timeframes. In order for this to be achieved, there is a great demand for work management in production. Therefore, we have chosen to analyze improvement areas within the supervisor’s role.The purpose of this report is to investigate the supervisor’s situation in the construction industry.Furthermore, the purpose is to identify work-related tasks in the professional role that have the potential for efficiency enhancement.A frequency study has been conducted in three different workplaces where we have followed three different supervisors for a total of nine days to get an insight into how the supervisors spend theirtime. Interviews have been conducted with supervisors for an even broader view of the study. Literature search has been made where we have found theories that we also present. During the course of the study we have found that there are a few improvement areas. As an enhancement, we think digitalization should be implemented, and everyone should keep order and clean up afterwards, more feedback to employees, and develop communication.

    Tillfälliga modulhus - en ekonomisk och kvalitetsmässig analys2016Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    The populations of Sweden are right now facing an acute housing shortage. One of the reasons of this is the huge amount of immigrants that have been taken in over recent years. The construction industry hasn’t been able to keep up with the rising demand and is right now looking for a solution. Modular housing is one solution that has been proposed by Boverket, the national board of housing, building and planning as it reduces construction times. The purpose of this paper is to analyze this method and the potential consequences/gains it has. In this paper we have used three different case studies were we have done 3 interviews in each.   This research concludes that the problem doesn’t lie within the quality or the costs associated with modular housing. It lies within the temporary building permits that are often used when time is of the essence.

    Hållfasthet i helväggselement av cementbunden träull2018Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Cement bonded wood-wool as external walls have been used around the world since the 1980s. They can have different appearances, wood-wool slabs connected to each other into larger wall elements that are raised between concrete columns and beams. Another type is hollow wood-wool blocks that are stacked on each other and filled with concrete to make an external wall. In 2004 a new building system was launched in Sweden, large prefabricated wall elements of wood-wool. They are connected to each other with concrete columns and beams integrated in the elements to make an external wall. This report is looking into if the concrete beams and columns for the building system are needed. In the report three different tests were made to get the mechanical properties of the prefabricated wood-wool elements. Results showed that there was a large different in the density between the wall elements and it also showed that the modulus of rupture varied between 0.248-0.449 MPa on three identical wall elements. The characteristic modulus of rupture was three times higher than documented in previous reports of a similar wall. The conclusion of this report is that the concrete beams and columns should still be in the wall system.

    Abstract [en]

    The traditional building techniques in Ethiopia today contain a lot of wood. Because ofdeforestation the forest cover in the country has been decreased. A part of a solution would bethe exclusion of wood in construction and then the adobe technology is a good alternative. Adobe technology involves blocks made from local soil that mixed with water and straw asreinforcement. The sundried blocks can be bricked up to walls. As mortar the same wetmixture can be used.

    This report contains analyzed soil characteristics in the high altitude located Asella region todetermine its suitability for adobe blocks. The design of a kindergarten in Alem Maya is alsocarried out.

    En villaleverantörs möjlighet till etablering i Finland: analys av för- och nackdelar2015Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    The construction market has, as a result of the crisis in Europe been uncertain in recent years. During the year 2013, the construction will be stabilized, in particular Finland. The geographical proximity between Sweden and Finland and similarities in cultures and climates makes Finland a coveted market for many Swedish companies.

    Differences in national regulations and guidelines, which are produced by the authorities in different countries, are examples of barriers that may hamper the process, including for Swedish villa suppliers, to establish themselves on the Finnish market. It may be useful when facing a new export drive, to look up what similarities and differences there are between the countries building codes, to prevent mistakes and unnecessary costs to the project work.

    Abstract [en]

    This final project is an investigation about the responsibility in rooms where the walls and floors are exposed or partly exposed to irrigation of water, as a bathroom, laundry room and WC.

     

    The cost for all water damage is valued for 5 000 000 000 SEK each year. How is this possible with all information about the problem and good materials? Who is responsible?

     

    Incites had been made in the subject throw reading reports and participation in courses about how to make a room mention above. Discussions have been made with workers in the trade of making the walls waterproof.

    The conclusion in the rapport is about who´s responsible for the damages and will pay the cost of the renovation. The responsibility is discussed between the contractor and the insurance company. If the room is waterproof system is made by the rules the insurance company pays. If it’s not the contractor is paying or if they don’t know how the carpenter is the owner has to pay for the new bathroom.

    Fukt i samverkanskonstruktioner: Bjälklag i KL-trä och betong2019Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    Timber-concrete composites is more and more frequently used in timber structures, as the structures grow taller and taller. This is due to its ability to increase the span of the slabs, improve the acoustic characteristics and improve the capacity of side loads, such as wind loads. The issue when executing this kind of composites is the different materials and how they react differently to moisture. Despite this, there is not much research on the subject. The purpose of this report is therefore to investigate what moisture contents to expect, both on short- and long-term, when different kind of executions of the timber-concrete slab is applied and what impact these values could lead to. The aim has been to contribute to a better understanding of what impact moisture in timber-concrete composites have, and how to handle this. To find out the moisture content, both laboratory tests and simulations has been carried out. From these tests we have been able to make calculations and assumptions in order to give suggestions on moisture barriers between the materials.

    Brandkrav, branddimensionering och brandskydd för trätakstolar: Ur ett konstruktörsperspektiv2018Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    This study contains a compilation and a clarification of the rules and requirements that can be applied to trusses and roof structures in consideration to fire. The different steps to decide the fire resistance of a truss or a roof construction is not that distinct and has to be combined with experience and subjective assessment. In case of fire the load combination for accidental load is used and in comparison with the ultimate limit state, the loads are reduced. Two different methods have been presented to determined the strength of construction timber, when exposed to fire. Both methods showed that construction timber, with a width of 45 mm, had a strength that correlate to a fire resistance of zero minutes. To improve the fire resistance of a roof construction different methods to protect the element has been presented. The most efficient ways to protect the construction is with gypsum boards and rockwool but for lower requirements wood covering can also be used. Fire retardant treatment (FTR) and fire protecting paint are also presented but are not applicable on wood trusses due to that FTR decreases the strength and fire protecting paint needs larger dimensions. In order to illustrate the different steps that are used when determining fire requirements of roof structures, two fictitious examples is presented.

    Hur uppnår vi god inomhusmiljö i förskolan idag?2014Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    Abstract:

    This thesis work has been conducted at the Real Estate Department in Halmstad.

    The department consists of a construction/project management-unit and an operation/management-unit.

    Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.

    Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.

    Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.

    The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.

    I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.

    In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.

    The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.

    There were some differences between the staff-responses at the three different preschools.

    At Askens preschool they feel that the premises are cleaned poorly.

    At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows. The only common factor is the problems they have with the noise the children makes, which unfortunately is normal and specific for the activity.

    The particle measurement shows that Askens preschool is the one with the most particles in the indoor-air, which can be the results of poor cleaning och materials that are hard to clean.

    The airflow measurements didn´t show any unusual values, at those preschools where the measurements went well.

    Chalmersmodellens applicering på starkt överkonsoliderad lera2009Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    In this master’s thesis real settlements for the over consolidated clay below Arenahallen in Halmstad are compared with two different models for settlement calculations; Chalmersmodellen without creep and Chalmersmodellen with creep. Chalmersmodellen with creep is based on Terzaghi’s consolidation theory with an addition to creep. The purpose has been to find out whether Chalmersmodellen with creep can be used for this clay or if Chalmersmodellen without creep should be used instead. The problem has been solved with detailed studies of literature, sampling of undisturbed flasks of clay with geotechnical boring trailer and tries of compression with an odometer of the flasks in question. Thereafter the evaluated results from the odometer were used in Chalmersmodellen.

    After complementary of the real settlement, where not all measurements exist, the results of our researches showed that Chalmersmodellen with creep were overestimating the settlement before the preconsolidation stress has been reached.

    Prefabricerade betongbroar - är det möjligt?2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    ”Prefabricerad broproduktion ger ett snabbt montage och stor möjlighet att styra produktionsprocessen”

    (En av de intervjuade)

    Vid traditionell produktion av betongbroar tillverkas bron på plats. Ingående arbeten såsom byggande och rivning av ställning, formsättning, armering samt gjutning av bron är tidskrävande moment som innefattar oergonomiska arbetsställningar för yrkesarbetarna, där de dessutom exponeras för ogynnsamma väderförhållanden och höga höjder. De flesta betongbroar som byggs i Sverige utförs fortfarande enligt traditionella metoder innehållande många tidskrävande och ogynnsamma arbetsmoment.

    I rapporten behandlas prefabricerade betongbroar som är ett konkurrenskraftigt alternativ vid broproduktion. Broelementen tillverkas på fabrik och monteras på plats, vilket leder till tidsvinster, minskade trafikstörningar, förbättrad arbetsmiljö och bättre kvalitet. Prefabricerade betongbroar kan ses som en del av industrialiseringen av byggprocessen där standardiserade lösningar och metoder används för att effektivisera byggandet.

    Intervjuer med personer verksamma inom anläggningsbranschen har gjorts för att få fram ett så relevant resultat som möjligt. Dessa gav oss en övergripande uppfattning om prefabricerade betongbroars fördelar och nackdelar samt anledningarna till det låga användandet i Sverige.

    Rapporten visar att prefabricerade betongbroar är en möjlig produktionsmetod vid brobyggnad. De kvalitetsproblem som förekommit har arbetats bort, istället uppnås idag en bättre kvalitet på den färdiga bron. Beställarna måste dock värdera tidsaspekten redan i upphandlingsfasen för att prefabricerade betongbroar ska anses fördelaktiga. Dessutom måste projekteringsprocessen förändras och en ny kompetens arbetas fram inom branschen. Förändras dessa faktorer är vi helt övertygade om att prefabricerande betongbroar har en ljus framtid i Sverige.

    Optimering av betong med Byggcement (CEM II) till håldäcksproduktion2011Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    This thesis has been developed inassociation with Strängbetong AB, Sweden.

    A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.

    Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.

    This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. 

    Laboratory and factoryexperiments were made, to investigate the transition.

    Standardisering av snöröjningsplan: Instruktioner, råd och tips för snöröjning av tak med stora spännvidder2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The Swedish winters 2009/10 and 2010/11 were rich in snow and many roofs collapsed, mainly largespan frames. Investigations were made and the amount of snow was not the primary cause, insteadthere were several other causes. One of these was that in some cases roofs were shoveled in anunfavorable manner which affected the load patterns negatively, so causing the roofs to collapse.Most people lack the knowledge of how shoveling will affect the roof. Had there been an increasedunderstanding regarding shoveling, some roofs could have been prevented from collapsing.

    Through both qualitative and quantitative research in the form of interviews and calculations thetheoretically best ways to shovel a selection of roof types is presented in the report. The roofstructures covered are 3-compartment, continuous and Gerberspliced metal roof decks. Thecalculations only concern the bending moments in the decks. The results show that differentmethods are required depending on the type of structure. Therefore it is very important to knowwhat kind of a building is to be shoveled.

    To ensure that this information should be easy to understand and apply, a template has beendesigned with tips and advice for the structural engineer on how to establish a plan for shoveling.The plan for shoveling should then be passed on to the property owner with instructions, tips andadvice on how to attend to his property before, during and after the snow has fallen.

    Övergången till Eurokod 2: En konsekvensanalys2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Från och med den 1 januari 2011 kommer Sverige att gå över från Boverkets konstruktionsregler (BKR) till de, för den europeiska gemenskapen, gemensamma beräkningsreglerna Eurokoderna. De kommer att vara obligatoriska för alla bärande konstruktioner. Övergången kommer att innebära stora förändringar främst i konstruktörens vardag men man kommer även att se spår av den inom bland annat prefab-industrin. Rapportens tyngdpunkt ligger i att se på de faktorer som direkt berör betongelementindustrin. För att bättre förstå vilka förändringar övergången kommer att medföra för dels betongkonstruktören men också de konkreta förändringarna vad gäller armeringsmängd, sprickbreddsberäkningar och förankringslängder har dels ett ingående studium av de nya normerna samt en beräkningsjämförelse normerna emellan utförts.

    Normerna skiljer sig åt, men det är inte någon revolutionerande förändring då de båda bygger på samma dimensioneringsmetod. Den största skillnaden är att man, enligt Eurokoderna, lägger hela säkerheten på lastsidan.

    Huruvida armeringsmängden kommer, som man befarar, att öka är svårt att säga, även om mycket tyder på det. Dock skall påpekas att Eurokoderna ger en möjlighet att utföra vissa bärverk oarmerade eller lätt armerade.

    Sprickbreddskraven är de samma men dimensioneringsgången är något annorlunda. Vidare ges utrymme för att kontrollera huruvida kravet uppfylls utan att utföra beräkningar.

    Dimensionerandet av förankringslängder är mycket likt, normerna emellan. Men även här finns det möjlighet för konstruktören utföra dimensioneringen praktiskt taget utan beräkningar.

    Dimensionering av fästplåtar enligt Eurokod2011Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    I dagsläget finns ingen bearbetad beräkningsmodell för fästplåtar enligt Eurokod. Syftet med detta examensarbete är att utforma en fungerande och lättförståelig beräkningsmodell för dessa fästplåtar. Arbetet har begränsats till fästplåtar med fyra och sex förankringar bestående av varmvalsat stål samt armeringsstänger som förankring. Beräkningsmodellen är uppbyggt med hjälp av studier på gamla beräkningar samt nya aspekter som anses vara relevanta som sedan översatts till Eurokod.  Fästplåten har analyserats utifrån normalkraft, tvärkraft och moment samt samverkan mellan dessa krafter. Varje ingående konstruktionsdels kraftkapacitet har kontrollerats och sedan sammanställts till en totalt tillåten kraft. För att ytterligare underlätta beräkningsmodellen har ett beräkningsprogram i Excel utarbetats. För att slutligen verifiera beräkningsmodellen har verkliga tester utförts.

    Abstract [en]

    Statistics of occupational injuries show that bricklayers are among the most exposed, with heavy lifting by far the most common cause of long-term sick leave. Prefabricated brick beams create yet another risk of injuries that can be prevented by auxiliary equipment or alternative solutions. From articles, interviews with masons and from a survey carried out in conjunction with this report, it appears that there are frequently difficulties in the use of available means for lifting and handling. Previous studies on the subject of transverse reinforcement in masonry beams indicate a viable method for bridging large openings in masonry walls. This bachelor thesis delves into whether the idea could be realized in today's brick construction with a view to improving occupational health and safety. Within the project a method, applicable in today's manufacturing of pre-stressed brick beams enabling mounting of vertical reinforcement, was developed and tested.

    Early Procurement by Partnering2003Inngår i: Construction economics and organization: Proceedings of the 3rd Nordic Conference on Construction Economics and Organization, 23-24 April 2003, Lund, Sweden / [ed] Bengt Hansson & Anne Landin, Lund: Division of Construction Management, Lund Institute of Technology, Lund University , 2003, s. 191-198Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The procurement strategy ”Partnering” has been and is used in Sweden, although to a rather limited extent. One variant of this strategy is when the contractor very actively works in the market in order to get in touch with a client and in order to enter into a building or construction project in a very early phase. This variant can be called ”Early Procurement by Partnering” (EPP). This paper describes a project with the aim of studying and analysing this special procurement strategy.

    Based on interviews with four individuals, three cases are described and analysed.

    The results of the project are mainly the following:

    • In order to have successful EPP-activities, the construction company must have employees with a suitable character, attitude and interest and with appropriate technical and economic competence.

    • EPP-projects can have a great economic importance for a local division of a construction company. It has not been possible, however, to express this importance in quantitative terms.

    • The interviewed individuals have mentioned that there are several advantages of EPP-projects. Among the most important is a simplified situation for the client and possibilities for the construction company to have long-range planning and to take its experience and wishes into consideration at the design stage. For individuals within the construction company the main advantage is that they have the possibility of joining a project very early and thereby having the potential to influence it and to be creative and innovative.

    Sustainable Low-Cost Housing: new technology and attitudes – the importance of creating awareness. A discussion based on results obtained in a pre-study2006Inngår i: Konferensen Hälsa möter teknik, Varberg 18-19 september 2005, Tokyo: SB05 Tokyo National Conference Board , 2006, s. 8-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    One of the most serious problems in Ethiopia today is the rapid pace of de-forestation. The consequences are well-known: soil-erosion, shortage of fire-wood and, to a certain extent, lack of timber for construction. In Ethiopia some of the most durable indigenous species have been almost eradicated due to de-forestation.

    Against this background a research project named “Sustainable Low Cost Housing – needs, possibilities and attitudes. A project with focus on the Kambaata Region in Ethiopia” has been initiated at Halmstad University. The aim of the project, which is interdisciplinary, is to develop and introduce a new low-cost housing technology and to analyse attitudes towards low-cost housing. This project has been preceded by a pre- study which forms the basis for this paper. The aim of the pre-study was mainly to gather necessary information on which the planning of the major project could be based

    One of the main conclusions of the pre-study is that developing a new technology alone is not enough. An introduction of a new technology must take societies’ attitudes into account, if it shall be successful. This can be done by an active and systematic awareness building. This, in its turn, must however be based on further research about attitudes towards low-cost housing technology.

    The demonstration project as a tool for introduction of sustainable low cost housing – some experiences from Ethiopia2011Inngår i: Innovation and Sustainable Construction in developing countries / [ed] Ben Obinero Uwakweh, Hanoi: Construction Publishing House , 2011, s. 133-137Konferansepaper (Fagfellevurdert)
    Abstract [en]

    One of many serious problems in Ethiopia today is the rapid pace of deforestation. This accelerates fire-wood shortage and put a high stress on the natural resources including timber for construction. Based on the assumption that low cost housing based on soil is an economically viable and environmentally sound choice, a research programme at Halmstad University was initiated in 2004. This research, aiming at the Kambaata Region in Southern Ethiopia, has focused on the introduction of adobe technology and cement stabilised soil block technology.

    A final stage of this research programme is to erect demonstration buildings. Its objective is to demonstrate new building technologies and to use the demonstration buildings as reference objects in studies regarding building technique and attitudes towards these new technologies.

    This paper is focused on the role of demonstration projects at the introduction of sustainable low cost housing. As an introductory background some executed demonstration projects are described and their impact is analysed. Against this background, a currently executed demonstration project is described.

    Introduction of Sustainable Low-cost Housing in Ethiopia – an Innovation Diffusion Perspective2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    As many developing countries, Ethiopia is facing a lot of problems. A high population growth and erosion caused by deforestation can be considered the most serious one. The need for housing is increasing while deforestation causes a lack of sustainable and appropriate timber for construction. A challenge facing the Ethiopian society is thus to give a growing population opportunities to obtain decent, sustainable and affordable housing. One way to achieve this is to use adobe technology, which means that houses are built with sun-dried clay blocks. Used correctly, the adobe technology has many benefits. The main advantages are that the technique is relatively simple, local materials can be used and that timber demand is low. Because of this, the technology also has many advantages from a sustain ability perspective. In Ethiopia, most attempts with the adobe technology have been less successful without lasting impacts. In this paper, the reasons for this are discussed. Six cases where adobe has been used are described an analysed. Many factors have been identified as being important for the diffusion of the technology, i.e., a strong champion, market and risk factors, cultural factors creating stigma and basic training. © 2015 Published by Elsevier B.V.

    Report-evaluation of multi-storey Low Energy Houses at Hertings Gård, Falkenberg2010Rapport (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    The new residential buildings at Hertings Gård in Falkenberg are built and owned by the local municipal housing company, Falkenbergs Bostads AB (FaBo) during 2007-2010. It is a good example of when knowledge of Passive house technology combined with good energy planning and project management can result in multi-storey houses with energy rating under 50kWh/m2. The multi-storey houses at Hertings Gård have innovative solar air heating systems connected to the ventilation system that is quiet unique. The solar air heating system contributes to the buildings energy supply by preheating the ventilation supply air. (The solar air is part of another project in Energy in Minds). This evaluation is based on metered energy used for space heat, domestic hot water, electricity for building service and domestic electricity for two of the multi-storey houses during 2009, House 18 and 19. The result is presented as monthly uses and compared with initial project specifications and some other parameters. The total initial energy specifications set by Concerto/Energy in Minds and FaBo for the houses are almost reached. Results are for House 18 and 19, 76,8 and 77,5 kWh/m2. (Specification 75 kWh/m2) This is total use of purchased energy. (excl. lighting at parking lots, not corrected after Swedish statistical normal year.) If we exclude the domestic energy use, the results looks as follows, House 18 47,8 and House 19 45,9 kWh/m2.(Specification: 50 kWh/m2). The used domestic energy for 2009 is varying a lot (House 18 from about 650 kWh up to 6500 kWh) between the apartments and is in total roughly 20% more than was expected in the project. A conclusion is that domestic energy is most of all a result of the tenant’s individual needs and behavior. Another energy specification that is not fully reached is the electricity for building service which is slightly more than specified in the project. The efficiency of the ventilation system is analyzed (with Specific Fan Power, SFP=2,80) which is relatively high compared to recommendations in National Swedish building code. This is probably a consequence of the chosen ventilation system with functions such as individual indoor temperature control. This function needs a design of the ventilation system that causes more power drops and therefore also more power than a more traditional and centralized ventilation system. The energy used for domestic hot water (DHW) is about 26% lower than specified in the project. (14,75 kWh/m2, year vs 20 kWh/ m2, year). The metered average specific DHW use at Hertings Gård is 0,27 m3/m2 and year. This is just slightly over the average of about 128 000 German apartments with individual metering and charging of DHW (0,25 m3/m2 and year). Hertings Gård has individual metering and charging of DHW use and low-flush water taps which are contributing to this relatively low DHW use. What is also achieved at Hertings Gård is, at least when looking at the tenant’s answers in the completed survey, that it seems to be a valued housing for its comfort as well as in other quality aspects. Many tenants can recommend the housing to other people. In conclusion, Hertings Gård is a good housing for the tenants, most probably a good investment for the housing company and above all a good living for the environment and the climate.

    Tillämpning av kolfiberförstärkning i bärande betongkonstruktioner: Jämförelse med stål som förstärkningsmaterial2016Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    Strengthening of existing structures with Carbon Fibre Reinforced Polymers (CFRP) is a method that has been more common in the building sector during the last decades. The materials strength in relation to its weight is a huge advantage but the lack of knowledge in the building sector results that professionals uses more proven materials such as steel to strength structures. In this report five minor projects in which steel was the strengthening material has been analysed to see if CFRP could be a competitive strengthening material considering mainly practical and economical aspects. The main purpose of this report was to evaluate when CFRP is the most suitable option for strengthening of concrete structures. The results showed that CFRP was applicable in every project but the total cost were higher comparing to the steel solution in four out of five projects. The results indicate that it is difficult to motivate CFRP regarding the economical aspect in relation to minor project that were evaluated in this report. Nevertheless, the tendency is that the advantages with CFRP is more useful when there are more comprehensive projects such as advanced steel works and when it is necessary to save room volumes.

    Självkompakterande betong: Kvalitetspåverkande faktorer inom anläggningsbranschen2010Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Self-compacting concrete is still considered a relatively new product in the construction industry. This type of concrete is rarely used within cast in place concrete. The industry is rather conservative towards new technology and few are willing to take the economic consequences if the casting fails.

    During the years self-compacting concrete has been used in Sweden, many failures occurred which has led to a fear of using the product. Manufactures and contractors have not understood how sensitive the concrete is and that you have to be very careful during manufacture and handling.

    The aim with this work was to find out what makes self-compacting concrete a sensitive product and what affects it.

    Self-compacting concrete is at the limit towards separation which requires great care during manufacture and casting. Even at very small changes of the available amount of water the concrete’s flowing properties, distribution and stability can be affected relatively strongly.

    The quality of the fresh concrete has large impact on the final results. As the mixing operator it is important to get the right information and be careful during production. The transport affects the concrete consistency but how much we do not know at present. Since several factors such as air temperature, humidity and wind conditions vary constantly it is hard to determine the impact of the transport alone.

    It is important to create experience of handling of self compacting concrete in order to solve the problems and to change the setting within the industry to self-compacting concrete.

    Riskbedömning för mikrobiell påväxt i ett välisolerat parallelltak2016Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    Nine out of ten small houses in Sweden are today constructed with cold ventilated roofs with attics. In a study made in Sweden, 72 % of these have shown high moisture conditions which have led to moisture related damages. To avoid these problems, and also get a larger volume inside, it has become more usual to build parallel roofs.

    Because of the parallel roofs sealed construction an inspection is not accomplishable. Some studies have been made by computer programs to investigate the risk of moisture damages and mould growth in this kind of roof.

    The purpose with this study was, with practical measurements, to examine if moisture problems occur in parallel roofs. The practical measurements were processed in the airgap and wood and registered relative humidity and temperature to give information about the condition of the wood and possible mould growth.To compare the results from the practical measurements, simulations were made in Wufi Pro 5.3 and Wufi Bio 3.2.

    The simulations showed lower relative humidity than the practical measurements, which can be explained by the limits of the programs and also misleading settings. The practical measurements showed very high relative humidity throughout the roof. By this reason the parallel roof cannot be considered risk-free from a moisture point of view.

    Passivhus: Särkostnader vid produktion2010Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [sv]

    En av orsakerna till att det inte byggs fler passivhus i Sverige är de ökade kostnaderna. I detta examensarbete genomförs en grundlig jämförelse mellan fyra olika passivhusprojekt och konventionella projekt. Jämförelsen görs kring de olika processerna i projektet: projektering, byggande och förvaltning. Den största vikten är lagd kring byggandet där byggnadsdelarna, grund, vägg och tak, jämförs med konventionellt byggande, för att få fram särkostnader för passivhus. Denna information ska förhoppningsvis underlätta för beställaren.

    I den teorietiska bakgrunden ges en grundläggande presentation av litteraturstudierna om passivhus, dess historia, krav, kostnader, m.m. Den största delen av examensarbetet bygger på intervjuer med plastchefer och arbetsledare från fyra olika passivhusprojekt. Detta presenteras i fyra olika praktikfall där informationen från intervjun indelas i projektering, byggande och förvaltning samt en kostnadsdel som har stor vikt i examensarbetet. Programmet BidCon användes för att få fram uppgifter om tid, material- och totalkostnader kring klimatskalet i praktikfallen. Detta sammanställdes i en modell som skapades för att ge en överskådlig bild över praktikfallen.

    Dessa praktikfall analyserades och sammanställdes till en modell med samma syfte som de övriga i varje praktikfall. Resultatet blev att ett antal slutsatser kunde dras utifrån särkostnader kring projektering och byggande men några rimliga slutsatser kunde inte dras vid förvaltning.

    PlusTak2010Student paper other, 15 poäng / 22,5 hpOppgave
    Abstract [en]

    Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today.

     

    The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market.

     

    During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts. The project group has also participated in the use of PlusTak at various construction sites this spring, to get a better view of what could be further developed with the product. The outcome is a complete roofing system which is almost entirely prefabricated, and only requires a few hours on the construction site for completion of a fully weather protected roof. PlusTak is a very flexible system which is perfectly suitable for different house and roof types, and fits almost any roof pitch. The visible layer of the roof is available both as a classic seamed tin roof and with traditional tiles. Thanks to the great capability of insulation within the PlusTak system it suits the modern energy efficient houses perfectly. Moreover the insulation layer of the roof is placed in the outer roof, which eliminates the problems concerning condensation that occurs in weather and temperature changes, which has been a growing issue lately.

    Thus, PlusTak offers a cost-effective roof system of the as well as it provides a totally carefree ownership.

     

    An intense marketing campaign has been conducted through several channels during the development of the product. PlusTak was presented with great success at Nordbyggmässan in Stockholm, the biggest construction fair in Scandinavia, in March 2010. This was right after the product became patent pending. PlusTak has currently sold for over one million SEK and has been quoted on request for over 40 million SEK.  The annual market in Sweden corresponds to over two billion, despite the current recession. The project group is counting on taking over 2-10% of that market within a period of five years.

    Optimering av fackverksmodellering: Ett makro för Tekla Structures2013Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    This project is the result of a cooperation between HalmstadUniversity and EABAB. The aim of the project was to create a macro that would help EABAB automate the process of designing steel trusses. When run in Microsoft Excel, the macro imports and processes coordinates from a calculator program. The data is then imported into the Building Information Modelling software Tekla Structures, which creates a 3D structural model of the steel truss.

    The macro saves much time in the project planning process and also helps minimize the risk of design flaws caused by human error.

    Industriellt byggande: En analys av olika system och framgångsfaktorer inom industriellt flerbostadsbyggande2010Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Rapporten är ett examensarbete i byggingenjörsutbildningen på högskolan i Halmstad och belyser området för industriellt flerbostadsbyggande. Flera aktörer har försökt sig på att bemästra denna konst att bygga industriellt men inte lyckats. I denna rapport har vi gett oss på att ta reda på framgångsfaktorer. När det industriella byggandet jämförs med det traditionella byggandet finns det många olikheter som måste redas ut och göras om för att få en fungerande byggindustri.

    I rapporten ger vi er en allmän bild, och definition, av industriellt byggande. Vi jämför de olika aktörerna och försöker peka på vad som skiljer dessa åt. Genom intervjuer och litterära studier har vi också fått insatta personers syn på industriellt byggande och dess framtid. Vårt huvudsakliga mål var att identifiera framgångsfaktorer.

    Då detta är ett relativt nytt och outforskat område så omfattar rapportens resultat främst saker som är utvecklingsbara. Logistiken och dess planering är ett exempel på en utvecklingsbar faktor. Andra saker som vi kom fram till var, tidigt och väl styrt ledarskap, kundmedvetenhet med flera.

    Numerical Analysis of Point-Fixed Glass Balustrades2019Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    The design approach is currently very diverse for glass. It differs greatly between European countries and there is not one definite method for the design of glass components. Research in this field has a potential for better design optimization and industry professionals express a limitation of tools and knowledge about glass structure design.The purpose of this study is to analyze glass balustrades with point-fixings and to test a structural verification approach using a Finite Element (FE) software. The theory provides insight of glass as a structural material, different interlayers used for laminated glass, joints and connections, as well as design standards, concepts and regulations. Different models of varying configurations and geometries are created from the evaluation of balustrades with point-fixings available on the Swedish market and the theory. The models represent a glass balustrade with 4- or 6-point-fixings and is regarded as a fully toughened laminated glass component with different stiff and standard interlayers. The structural analysis of point-fixed glass balustrades on the Swedish market indicated a lower stress and deflection resistance capacity than the pre-normative Eurocode criterion. Based on the FE calculations, some guidelines for fulfilling the criterion are proposed.To make glass more generally applicable as a load-bearing material, the limitations of the FE-software, and how the parameters affect the calculation results needs to be taken into consideration. In order to evaluate the interlayers used for the model, a parametric study using FE-analysiswas carried out, in which the maximum stresses and deflections for several variations were calculated. A sensitivity analysis of the balustrade was conducted to evaluate various geometric and material parameters and how they affect the FE software-based model. Comparisons of guidelines and national codes for simplified hand-calculation and the FE-approach were made to obtain some understanding of calculation methods used in the glass industry and to evaluate the results of the structural analysis. The study suggests that the FE approach is an effective method for a relatively quick and easy verification of glass balustrades.

    Böj- och böjvridknäckning av stålpelare enligt Eurokod 3: Beräkningshjälpmedel2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Metoden för att dimensionera stålpelare med avseende på böj- och böjvridknäckning enligt Eurokod 3 är omständlig och tidskrävande. Syftet med arbetet var att skapa beräkningshjälpmedel som underlättar dimensionering för hand enligt Eurokod 3. Först studerades bakgrunden till de befintliga dimensioneringsformlerna, hur de uppkommit och varför de ser ut som de gör. Sedan kunde hjälpmedel i form av interaktionsdiagram och tabeller tas fram. Interaktionsdiagrammen visar t.ex. olika kombinationer av tillåten normalkraft och moment för olika pelarprofiler och längder. För att göra det möjligt att konstruera interaktionsdiagram har tre specifika lastfall behandlats. Dessutom har arbetet begränsats till de vanligaste varmvalsade stålprofilerna. Resultatet har redovisats i en handbok med interaktionsdiagram för de olika fallen och profilerna. Dimensioneringshjälpmedlen förkortar beräkningstiden avsevärt vid handberäkningar.

    Abstract [en]

    After studying the city and the localization of the land, we decided our idea. At first we thought to make a student accommodation, but there is one so near of the land, then we changed our way of think making something less typical.Therefore, we decided to make an old people ́s home there because it is a quite and peaceful place next to city centre. The building ́s views are oriented to the Nissan river.The principal object of this project is to provide a place where old people can live with all the cares and where have the necessary personal to take care them.The building has only one floor, there are: dining room, laundry, bathrooms geriatric, gym, common toilets, staff areas, medical office, kitchen, storage area. The hall has very high roof with a big window, with view to the river, to get light in a very big area.Inside the buiding It have 8 double rooms and 6 single rooms, with bathroom included in each. Are also included geriatric bathrooms that satisface the needs of its users. There are two interior courtyard that give light to the corridor which serve to communicate all the rooms and the medical center area and gym. Also exists various free-use bathrooms and entertainment areas for the costumers.

    Våningspåbyggnad: En fallstudie2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Studiens syfte är att undersöka vilka bekymmer som kan uppstå under delar av byggprocessennär våningspåbyggnader ska genomföras.

    Studien tar sin början i en teoretisk referensram. Denna beskriver hur flerbostadshusenhistoriskt är uppbyggda, detaljplaneprocessen, tillgänglighetsproblematik, brandhänsyn,upphandlingsalternativ, projekteringsprocessen, konstruktion, skador och reparationer avbetong, förstärkning, planering och logistik. Våningspåbyggnad är således en kompliceradprocess där flera olika aspekter måste beaktas. Fallstudier genomfördes för att få en stor breddoch förståelse för olika problem och möjligheter som kan uppstå under byggprocessen.

    Fyra stycken fall valdes ut. I varje fall intervjuades en representant från byggherre–,konstruktör– och entreprenörssidan. I fallstudierna undersöktes frågor kopplade tillbyggnadernas konstruktion, genomförandet av projektet samt övriga frågor kopplade till bl.a.regelverk och motivet till att genomföra projektet.

    Resultatet visar olika svårigheter och möjligheter som uppstått i de olika projekten. Problemsom uppstått löstes ofta på olika sätt. Arbetsprocessen såg olika ut i projekten.

    Avslutningsvis diskuteras resultatet, vissa kopplingar görs till relevant litteratur. Studiensslutsats är att våningspåbyggnader skiljer sig från nybyggnationer samt ställer högre krav påsamarbete och planering.

    APD- och logistikplaner i samband med väderskyddat byggande2010Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Avsikten med projektet har varit att hitta skillnader i APD- och logistikplaner i samband med väderskyddat byggande gentemot traditionellt byggande där väderskydd inte används. Spelar APD-planen en viktig roll när det gäller väderskydd? Kan man effektivisera byggandet med en smart APD- och logistikplan? Med hjälp av litteratur och fallstudier är detta frågor som vi ska försöka besvara. Använd litteratur består av forskarrapporter och tidigare examensarbeten. Projektet består av fallstudier där tre platschefer intervjuats. Efter intervjuerna sammanställdes platschefernas svar där likheter och skillnader tas upp.

    Resultatet från undersökta projekt visar att det är beroende på väderskyddets utseende om det är någon skillnad på utformning av logistikplaner. APD-planerna på de tre fallstudierna skiljer sig inte mot traditionellt byggande, det är samma tankegång.

    Samtliga platschefer säger att det ofta är problem med logistiken till byggarbetsplatsen. Vi tror inte enbart det beror på de leverantörer som levererar material utan att det är hela kedjan från råmaterial till färdig produkt. Det blir en dominoeffekt där den sista aktören i kedjan är den som blir mest drabbad. Om logistikkedjan från råmaterial till färdig produkt kan optimeras borde förseningar av leveranser till byggarbetsplasten kunna minskas. Vilket leder fram till att det finns pengar att spara för byggföretagen.

    Möjligheterna för Casabona-systemet2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats. In order to be able to expand they now want to launch their frame system, Casabona. Casabona consists of a lightweight steel frame integrated with the EPS-insulation, making it ideal for houses on the water. To allow the company to grow they now wants to introduce the frame system in houses on land. The purpose of this report is to find the problems or difficulties which may arise during the launch of a new product in an industry perceived as beeing conservative. In addition, we make a comparison between different framing systems where the advantages and disadvantages of respective framing systems is presented. All this is done in order to find out what chances a new framing system like Casabona has to establish itself on the market. The goal of this report is to get a greater understanding of how the construction industry looks on new products. In order to arrive at the analyses and the results we achieved, we first made a field study at Aquavillas production plant in Västervik. During our visit we gained a deeper understanding of how the Casabonas system is built up. We then began to study the litterature about steel structures in General. After that we read about two big companies on the Swedish market, Lindab and Gyproc who seperatly manufacture framing systems similar to Casabona. When we had gained a broader understanding of steel, we began to interview the companies operating in the construction industry in Halmstad. The interviews gave us a greater insight about what designers, installers and architects thought about steel constructions. The conclusion that we can draw from our results and our analyses is that Casabona has a good chance to enter the Swedish market. With a successful product Aquavilla will also acquire a strong brand and reach out to customers even easier. The report will cover 3 different framing system that we have reviewed and compared. We have listed the different system's pros and cons, and we have put these together in a comparison table.

    Från BIM-modell till beräkningsprogram: Kompatibilitet mellan Tekla Structures 21 och FEM-Design 15 3D Structures2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Building designing can be made by a powerful tool, BIM-programs. With these programs, you quickly get a view of future design. Elements of the model are intelligent, which means that they are more than just some dashes. These intelligent elements can be analytically studied with programs that make calculations according to finite element methods. This report describes the export of BIM-elements into a calculation program that calculates static using the finite element method. Applications for the method and appropriate project size and complexity is described in the report. The software used in the case studies in the report is the BIM modelling software Tekla Structures 21 and the calculation program FEM-Design 15. To determine if the connection between the chosen applications are possible, two case studies has been made. The case studies have shown that a one-way transfer from Tekla to the FEM-Design is possible and useful. But because the reversal is not possible when the calculations and analysis are completed, the method can't be implemented in an automatized BIM- design.

    Ombyggnad av flerbostadshus: Hur påverkas hyresgästerna av  en ombyggnad 2010Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    During the years 1950-75 was the construction of building apartments in high speed. A rapidly growing reconstruction requirement is the consequence of the rapid construction speed in these years. The technical lifetime of the different parts of the buildings is about to end and the needs for reconstruction is huge. One of Sweden's national environmental objectives is to reduce the urge of energy in buildings. This calls for radical measures to implement energy efficiency of existing assistance particularly in the assistance that is now facing reconstruction. Most of the apartments that are in need of reconstruction is leased and residents. No matter what kind of measures as deems most appropriate in a reconstruction project, it brings the different types of disturbances that affect the residents. The major disturbances that are perceived as most disturbing of the tenants are dust, noise and difficult accessibility. Temporary electricity, water and ventilation failure are other types of disturbances that often occur at a reconstruction project. In this thesis, most of the disturbances are identified and also some approaches to achieve the best possible way to reduce them. A reconstruction project in Karlskrona was visited, where participants as the property owner, contractor, professional men and tenants were interviewed. It is important to both the property owner and the contractor to ensure the reduction of disturbances as much as possible. It is obviously not easy to eliminate some of the disturbances but through good planning, sufficient information and to set requirements to the contractor in the form of legal framework for procurement and restrictions which should be register in the AF part (General Regulations), the effect of disturbances will successfully being reduced. The key to a successful reconstruction project with minimal disturbances to residents is primarily depended on the property owner's ambition, empathy and commitment to their tenants.

    Framtagning av handbok till Revit Structure2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Revit Structure är ett nytt 3D-modellerings program i Autodesks serie med ritprogram, speciellt utvecklad för byggnadsinformationsmodellering (BIM). Revit bygger på att användaren själv laddar in och placerar ut standardprofiler som till exempel pelare, balkar och väggar. När standardprofilerna är placerade i 3D-modellen kan de enkelt redigeras och förändras för att uppfylla de specifika kraven för just det byggnadsprojektet.    

     

    Den här rapporten är särskilt framtagen för att underlätta en övergång mellan programmen AutoCad och Revit Structure. Med rapporten följer en handbok som ska fungera som en introduktionskurs av programmet för studenter och konstruktörer.

     

    Handboken börjar med att gå igenom programmets upplägg och layout.  Där efter följer handboken ett byggnadsprojekt från start till mål. Varefter successivt byggnaden växer fram får användaren kunskaper om de vanliga verktygen då fler element tillförs och sammanfogas. I och med detta låter handbokens övningar användaren träna på de viktigaste verktygen på flera olika sätt och tillsammans med flera olika byggnadselement. Användaren får på det här sättet grundläggande kunskaper om programmet för att enkelt kunna fortsätta med fördjupande kurser eller mer avancerad litteratur.
