    Elnätets kapacitet för framtida belastningar från elbilar: En känslighetsanalys på ett av Halmstads lokalnät2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Regeringen har en vision att till 2050 ska Sverige uppnå en fordonsflotta som är fossilfri och för att uppnå den visionen ska el som drivmedel spela en avgörande roll på marknaden. HEM Nät AB är därmed intresserade av hur deras lokalnät i ett valt område kan påverkas när en större andel av hushållen införskaffar elbilar. Längs områdets högspänningsslinga finns nio nätstationer som matar ut effekt till 815 kunder. En känslighetsanalys genomfördes kring det valda lokalnätet med avseende till dess kapacitet idag till framtida belastningar från elbilar. Analysen baserades på fyra olika nätparametrar som möjligen kan riskeras med avseende till elbilars laddsystem: spänningsfall, transformatorbelastning, övertoner och osymmetri. Olika laddeffekter och kopplingssätt har även jämförts bland nätparametrarna för att visa vilken roll de kan ha i framtiden. Spänningsfallet samt transformatorbelastning för de båda effekterna 3,7 kW och 11 kW uppgick mot de satta nätkraven när 40 % respektive 20 % belastning sker i området. Två vetenskapliga metoder användes för att uppskatta övertonerna där ena tog hänsyn till en reduktion av sammanlagrade övertoner och den andra metoden använde en aritmetisk summering av strömövertonerna. Resultatet visade att med varken en inkluderad reduktion eller med den aritmetiska summeringen kommer övertonerna bli ett problem. Med simuleringen av osymmetri nåddes nätkravet när 7 % mer belastning skedde under en och samma fas. Slutligen kom studien fram till att lokalnätet är relativt starkt och kan klara av 322 elbilar vid 3,7 kW och 161 elbilar vid 11 kW.

    Procurement and Governance Choices for Collaborative Infrastructure Projects2018Inngår i: Journal of construction engineering and management, ISSN 0733-9364, E-ISSN 1943-7862, Vol. 144, nr 8, artikkel-id 04018071Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Collaborative approaches to infrastructure procurement are increasingly popular around the world due to their potential to provide improved project performance compared with more traditional approaches. The problem is that project outcomes continue to be unpredictable. Previous research has shown that this is the case regardless of whether the chosen procurement approach is based on price or non price selection of the project team. This is a major choice that clients make, but the presented research shows that governance choices for project execution are more important. This is significant because clients tend to focus more on procurement choices and typically do not differentiate governance based on those choices. This needs to change, and the authors show that optimal governance configurations vary on the basis of the chosen type of team configuration. For example, three specific governance arrangements for workshops are highlighted for single teams, and two specific governance arrangements for risk/reward sharing are highlighted for multiple teams. This study identifies governance actions that are associated with superior time and cost outcomes on collaborative infrastructure projects in Australia run by experienced public-sector clients under the two procurement scenarios. Based on a survey of 320 senior managers, independent sample t-tests were conducted to compare the application of governance actions among three distinct groups of projects, based on type of team selection and type of project outcome. The study provides evidence of the most effective approaches to project governance in a country that is a world leader. The results provide much needed recommendations for improved project performance based on large-scale quantitative analysis, which before now has not existed. Overall, the study recommends more attention be paid to noncontractual governance under both approaches to team selection, although the specific actions recommended vary. © 2018 American Society of Civil Engineers.

    Coordinating dangerous goods vehicles: C-ITS applications for safe road tunnels2015Inngår i: 2015 IEEE Intelligent Vehicles Symposium (IV), Piscataway, NJ: IEEE, 2015, s. 156-161, artikkel-id 7225679Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Despite the existing regulation efforts and measures, vehicles with dangerous goods still pose significant risks on public safety, especially in road tunnels. Solutions based on cooperative intelligent transportation system (C-ITS) are promising measures, however, they have received limited attention. We propose C-ITS applications that coordinate dangerous goods vehicles to minimize the risk by maintaining safe distances between them in road tunnels. Different mechanisms, including global centralized coordination, global distributed coordination, and local coordination, are proposed and investigated. A preliminary simulation is performed and demonstrates their effectiveness. © 2015 IEEE.

    Modernisering av en fotbollsarena: Örjans Vall2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The purpose of this study is to show the technical building requirements for modern arenas inSweden. The study will also create an understanding of how the requirements affect theSwedish football arenas which are affected by the regulations valid from 2014. As one of theSwedish football arenas there is Örjans Vall located in Halmstad. The aim of this study is todevelop alternative solutions regarding the technical problems Örjans Vall is facing 2014,when the new arena requirements for “Svensk elitfotboll” are taken into use. The solutions aremeant to be seen as suggestions which can inspire and guide the future planning for themodernization of Örjans Vall.In order to present a suggestion with technical building solutions the study contains differentphases. The first phase is an evaluation of the arena requirements and criteria, with focus onthe technical building requirements, which are of importance when creating solutions forÖrjans Vall. The second phase is a review of the arena situation in Sweden. The last phase isan evaluation of Örjans Vall made towards the previous evaluation of the requirements andcriteria as the basis.The evaluation of Örjans Vall shows which technical building defects the football arena have.A rebuild and expansion of Örjans Vall is essential and needs to take place before 2014 unlessan exemption is issued. When all the parts in a complete suggestion should be consideredfollows a discussion where each area is treated separately. All areas will then form the basisof a complete suggestion for how a future Örjans Vall could be designed. The basis for thediscussions are simple solutions were practical suggestions are presented. In the areas where asimple solution does not exist, other arenas in Sweden will be considered to inspire theproposal.The solutions include the defects in different areas but also renovations and extensions of thebleachers where the main defects are shown. The report presents four alternative renovationsand extensions of the bleachers where an overall proposal is developed to meet the spectatorinterests.

    Utökad samverkan med leverantörer: - Partnering, en lönsam möjlighet i byggindustrin?2013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The construction industry has been heavily criticized in the past few years for its development of productivity compared to the manufacturing industry. In 2009 the Social Care Center developed a report that treated och criticized different errors within the construction industry. For instance competence, construction errors and performance had showned bad results which had to be improved. A common sentence within the building industry is that ”every project is unique”.

     

    Today it’s common for a construction company to have costs for material and services which exceeds two-thirds of the total cost. The greater part of the total costs therefore does not lie within the companies internal organisation, but at the suppliers. Studies showed that external costs will increase in the future.

     

    New working methods from the manufacturing company, like Lean Construction and Partnering are starting to establish more and more in the building industry. The larger companies have learned how to use this new way of working but also the medium sized companies have started to show their interests for these methods that will work in a way of preventing problems, finding solutions and shrinking the costs.

     

    The construction company, Jonab, showed their interest for partnering and through earlier cooperation with Halmstad University it resulted in this final thesis. The scope of this thesis is to investigate with neutral view, Jonab’s business relationship focusing on the suppliers. From the perspective of partnering, we’ve given Jonab an overview over their relationships and recommendations on how to improve it with the use of partnering.

    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.

    Framtidens elbilar utmanar nutidens elnät: Påverkan av ett ökat antal elbilar på ett halländskt elnät2015Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years. After this timeframe the voltage drop becomes a serious concern and should be addressed.

    Effektivisera samverkan i BIM-projektering: Kommunikation & BSAB2016Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    The definition of BIM has been unclear since the very first beginning and many problems have occurred during the process, which have made the implementation of BIM not completed. Generally BIM can be described as working in 3D with object based tools, which contain massive of information to increase the efficiency information flow during the construction process. The aim for this report is to get a more understanding about the problems designers have encountered, in order to improve the efficiency of BIM design. Since many problems have occurred in the communication process, a Swedish company is making an upgrade of the BSAB-system, to make it more customized with BIM design. This study shows the new BSAB-system can improve the technical problems but it will not solve the social problems. It indicates that the human factor is the key to make the implementation of BIM completed. In order to achieve the goal of implementation, Sweden is in need of a national standard or a waypoint on how to work with BIM designs. The most important of all is the human attitude and the approach of learning.

    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.

    FRP i brokonstruktion: -varför används FRP inte i Sverige2015Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    FRP stands for Fiber Reinforced Polymer. FRP materials have yet to be introduced inbridge construction in Sweden. Composite materials can through combined componentsand manufacturing processes be tailored to fit advanced bridge designs. FRP materials arestrong, durable and of low weight. FRP materials give the superstructure reduced weightand are therefore a suitable alternative for industrial prefabrication. This report shows thatFRP materials are possible to use in bridge construction. With the introduction of a specificEurocode we are confident that FRP materials will become a competitive alternative inbridge construction in Sweden in the future.

    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.

    Managing short-term efficiency and long-term development through industrialized construction2014Inngår i: Construction Management and Economics, ISSN 0144-6193, E-ISSN 1466-433X, Vol. 32, nr 1-2, s. 97-108Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There is a strong need for a productive and innovative infrastructure sector because of its monetary value and importance for the development of a sustainable society. An increased level of industrialization is often proposed as a way to improve efficiency and productivity in construction projects. In prior literature on industrialized construction, there are however neither many studies addressing more long-term aspects of innovation and sustainability nor studies within the infrastructure context. Organizational theory suggests that firms need to be ambidextrous and focus on both long-term exploration of new knowledge and Technologies and short-term exploitation of current knowledge and technologies, in order to achieve sustainable development. Therefore, an investigation of how both short-term exploitative performance objectives and long-term explorative development can be addressed when implementing industrialized construction in infrastructure projects was conducted. A case study consisting of four infrastructure projects shows that the main drivers for increased industrialization are of an exploitative nature, focusing on cost savings and increased productivity through more efficient processes. The main barriers to increased industrialization are however related to both explorative and exploitative activities. Hence, by managing the identified barriers and explicitly addressing both exploitation and exploration, industrialized construction can improve both short-term efficiency and long-term innovation and sustainability. © 2013 Taylor & Francis.

    Informations- och kunskapsflöde i byggbranschen: En studie av informations- och kunskapsflöde till och från produktionsledare2011Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    This report that is written in cooperation with Peab Sverige AB, studies the information and knowledge management from the production support to the production management.

     

    The conclusion of this report is that to have a good and functional information and knowledge management it is necessary that the company has a good way of regain and handling experiences from its projects. The way to do this is to develop the managing system on the production management’s terms. It is also critical to find an easy way for the production management to use the system.

    Arbetsmiljöorganisation i byggbranschen2013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Ser man på ett tio års perspektiv, så har det i genomsnitt en person i månaden dött på den svenska byggbranschen. Många av dödsfallen beror på organisatoriska brister, det kan exempelvis vara att man gjort otillräcklig undersökning av arbetstagarens erfarenhet eller bristfälliga skyddsronder. I en studie uppskattades det att ungefär 60 % av Europas olyckor inom byggbranschen var direkt eller indirekt på grund av organisatoriska orsaker.

    I mitt projekt vill jag analysera hur ett byggföretag hanterar sin arbetsmiljöorganisation. Projektet är en fallstudie av hur företaget hanterade arbetsmiljöorganisationen i ett av byggprojekten. Vilket har genomförts av byggföretaget MTA Bygg och Anläggning. I projektet har jag begränsat arbetsmiljöorganisationen till roller inom arbetsmiljöorganisationen, förberedelser för arbetsmiljövänligt arbete samt systematiskt arbetsmiljöarbete.

    Genom litteraturstudier, internetstudier och kvalitativa intervjuer har jag undersökt vilka faktorer som ger en bra arbetsmiljöorganisation. Jag genomförde intervjuer med inom arbetsmiljöorganisation samt studerade dokument för arbetsmiljön hos företaget för att kunna analysera byggprojektet. Jag ville ta reda på hur företaget kunde förbättra sig och vad man skulle kunna lära av byggföretaget.

    Vad motiverar och engagerar yrkesarbetare i byggprojekt: Partnerings påverkan på motivation och engagemang2017Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Inom varje projektorganisation finns det olika individer som ska skapa en produkt av hög kvalitet enligt kundens krav och förväntningar. För att bedriva projekten på ett effektivt sätt med ett bra samarbete har partnering vuxit fram. För att lyckas skapa ett bra samarbete gäller det att motivera och engagera alla inblandade till att arbeta åt samma mål. Beteendet ändras dock inte automatiskt hos människor bara för att de arbetar i ett partnering-projekt. Kontinuerligt arbete krävs för att motivera och engagera individer under hela projektets gång. I den här studien kommer partnering hänvisas till ett arbetssätt för att uppnå samarbete, motivation och engagemang. Skapar projekten en arbetsmiljö som gör att anställda presterar på sin högsta nivå kan det leda till att produktionen blir effektivare. För att yrkesarbetarna ska prestera på sin högsta nivå är det viktigt att motivera och engagera dem under produktionen. Examensarbetets syfte var att undersöka hur yrkesarbetarna motiverades och engagerades och vad i partnering som kunde bidra med att skapa detta hos yrkesarbetarna. Studien har utförts med hjälp av informanter från Skanska, Hus Göteborg.

    Faktorer som gjorde att yrkesarbetarna blev motiverade var att de hade kul på jobbet och bra kollegor runt sig i arbetet. Det var också motiverande att vara delaktig och involverad i att skapa produkter med hög kvalitet. Många av informanterna menade att kundens mål och visioner var viktigt för att få möjlighet att skapa en produkt som når upp till förväntningarna. Genom att yrkesarbetarna får fokusera på mål och visioner samt vara med och sätta upp dem kan mer motivation och engagemang skapas. Partnering kan i teorin bidra till att skapa motivation och engagemang men det är upp till varje projektorganisation hur organisationen väljer att implementera samarbetsformen partnering i projektet. I resultatet kan inte något specifikt urskiljas kring vad det är i partnering som motiverar yrkesarbetarna. Det som motiverar yrkesarbetarna kan göras i alla projekt och det är upp till projektorganisationen men också varje anställd att skapa förutsättningar till att skapa en motiverande arbetsmiljö där de anställda upplever tillfredställelse och trivsel.

    Effektivisering av asfalttransporter: Enhetligt arbetssätt för styrning och tidsskrivning av asfalttransporter2013Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    The cost of transportation has strongly increased in the recent years, transportations which are a major part for the construction companies. Skanska Asphalt which is a part of Skanska Sverige AB has noticed that there are significant cost savings to be made with the purchasing of transports. The transports in this case is about asphalt, where the costs are about 10% of the outsourcing business turnover. The purpose of this thesis is to study the working practice that Skanska Asphalt are using today in controlling and time-writing, for the asphalt transportations. Resulting in recommendations on how to improve the working practice at Skanska Asphalt.

    This study was conducted with the help of a number of interviews with Skanska’s employees and with suppliers of transportation to describe the practices which are being used in during the asphalt transportation. In the construction industry, every project is different and varies. For every project there is a production manager in charge from and scheduling to the ordering of transportations. For ordering asphalt transportations it’s common today for the production manager to make calls directly to individual drivers or to the management for the contracted transportation suppliers.

    It’s mostly common in time-writing to use hand-written notes, but there are also times when the drivers are using PDA for which the transportation management endorses the correctness of drivers information. The major problem is that the charged time for transportation is too high compared to the actual time, because drivers tend to round up the time-writing to the full or half an hour.

    Efficiency enhancement within Skanska is important and a proposal for improving working practice that can lead to cost savings is to introduce a different type of tariff. This requires closer cooperation and higher demands on the suppliers of transportation. For this system to work, it’s important to get system support from the suppliers.

    With improved internal communication between production managers it’ll result in further efficiency enhancements being found and Skanska will be able to increase the utilization of the asphalt transportation. The planning of the asphalt transportations could improve even further if it had existed any kind of calculation template. If Skanska informs the transportation suppliers in the early stage before the project kicks off with some form of planning calendar with the correct number of vehicles, will make it easier for transportation providers to meet Skanska's transportation needs.

    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.

    BIM - Förvaltarens Framtid2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    For nearly twenty years people have been talking about Product models, but given that the building industry is so conservative, it is hard to implement new working methods. Product models are these days known as Building Information Modeling, BIM. People often say they work with BIM but they often forget the most important part, the information. A 3D model should be linked with characteristics and information. Information that can be invaluable for the facility manager.

    We have a vision that in the best of worlds the facility manager would be able to "walk" into the model and see what kind of installations are inside the wall or in the roof. You should be able to point at an object and gain complete information about operation and maintenance off the installation. You should also be able to gain information such as the name of the product and article number if you have to buy a new one. That’s why in our thesis we want to highlight the possibilities for the facility manager.

    In order to have high achievements with BIM, coordination is highly needed. All participants in the construction process have to work together at an early stage; they must have the possibility to affect the stage of inquiry. By having the facility manager connected to the process at an early stage, other members have the opportunity to understand what’s expected from them. In the same way the facility manager will understand if any of the requirements are unreasonable or difficult to solve. Planning must be allowed to cost money. A well planned project can later save a lot of money due to less problems at the building worksite. In a well planned project there will be less changes and less additional work. The key words are Coordination and review.

    During the facility management stage there are great opportunities to save money with BIM. The benefits of BIM have been shown and larger facility companies demand a model that work in the facility management stage. The greatest advantages are gained by the visual model that gives a greater understanding and a better base for decisions. There are also great advantages in more effective processes, better quality and better documentation for maintenance, operation, future rebuilding and future sale.

    To be able to get a good image of BIM, how it is used today and what expectations there are, we have interviewed facility managers, system manager and BIM experts. We have also researched information in reports and articles.

    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.

    Modeller för hållbar utveckling: - en analys av tillämplighet av befintliga modeller vid upprustning av Miljonprogram2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Areas within the so-called ”Miljonprogrammet” (Million programme) are in a desperate need of renovation. The areas comprises of 25 percent of the total housing stock in Sweden. The increased environmental awareness from both the general public and the decision makers has resulted in a variety of technological solutions but the problems are often wider then that and includes both social- economical- and ecological factors. To solve the problems and to renovate the areas in a sustainable way there are a need for holistic models for strategic planning. The engineering consulting firm SWECO has developed such model for sustainable development in developing countries. Can this model be a possible approach to the current situation?

    The concept “Sustainable City” was developed by SWECO on behalf of the Swedish government and the organisation SIDA to be presented at UN’s top meeting for sustainable development in Johannesburg 2002. The concept is based on three parts: Working method, Subsystems and Institutional factors. The model is based on a multidisciplinary approach to try to find synergies between the different solutions in the process. This report focuses on the first part, the working method, since the other parts of the concept doesn’t really apply to Swedish conditions.

    A thorough literature study within the range of sustainable development was conducted to build a theoretical understanding of the term Sustainable Development. The concept “Sustainable City” was analysed, a minor case study was also conducted to get a more detailed view of the real world of renovation.

    The Analyse and Result points to that the model may not be the perfect solution as the approach to working method for strategic planning within the “Miljonprogram”. The model is a well-structured method that is much based on Swedish research. There would be a need for significant changes to the concept to be adapted to work in the specific areas. A solution could be to take a step back and rebuild a new model customised for the actual areas within the “Miljonprogram”.

    Abstract [en]

    The Construction Process Forum was initiated by the Construction Council. The Construction Council is an organisation which supports cooperation between universities and the construction industry. The Construction Process Forum was formed through that chosen key persons were asked to come up with suggestions on how to create a more effective construction process plus how to improve the image of construction. The aim was also to increase the awareness among the participants of Construction Process Forum. This report narrates the result of one years work within the Construction Process Forum. The focus of this first year was the construction site and the changes needed of the construction process to create better conditions for the construction site. The Construction Process Forum ended with the formulation of a plan of action for the development of construction.

    Project Assessments in Construction and Real Estate: Analysing management of end-user needs and ensuring performance in the building life cycle. CREDIT Report 42010Rapport (Annet vitenskapelig)
    Abstract [en]

    In this report a generic model for the capture and assessment of end-user requirements and needs, the CREDIT carpenter model, has been developed. The main determinants of the model is the need for the project organisation (including the facilities management organisation) to ensure a thorough understanding of the end-user requirements and needs as well as an assessment through out the project process. The end-users and the project organisation are often working in two different value chains. This, among other things, means that they may not share a common understanding of the process. Apart from just assessing to what extent the requirements and needs has been achieved it is important to assess the process of accomplishing the desired result. This way it is possible to learn from what has worked well and what has not. There is some variation in what and how it is being assessed depending on what type of building it is. Assessments on housing are more inclined to focus on softer aspects, for example perception etc. In the other cases there are, generally, a more technical perspective. It may be an affect of how knowledgeable the users are. In regard to housing the users have possible less experience of construction and communicating their needs than in the case of offices etc. There is also a notable difference between approaches and interest on what to assess in the different countries. Sweden has a much more soft approach and an ambition of getting as many as possible to understand what is being assessed and for what reasons while Finland has a much more technical and measurable approach. The clients, naturally, play a large part in the construction process, also when it come to capturing and transferring the requirements and needs of the end-users. It is mainly the clients that initiate it. Maybe more surprisingly, they do perform a lot of the work themselves as well. Designers play an important role as do known end-users as well. During the project it is mainly the client that initiates the assessments, but the actors of the project process, designers and producers that perform it. Evaluating the degree of fulfilling the requirements and needs as well as assessing the process to enable learning is again mainly a client action both initiating and performing, the rest of the actors do not engage to any larger degree. The processes from begin of the brief to the end of construction have well developed routines as a part of the project management system. These routines are good enough to successfully fulfil the studied project and the control of the process in order to get internal efficiency in the short run perspective. But there is almost no case that shows any assessment tool that support feedback, the knowledge development and the innovation process which is important in the long-run perspective. The missing feedback is marked in the carpenter model. Found in the study there are two examples of tools that together may to some extent overrun this issue. Building Information Models have the potential of acting as an information carrier within a project, storing all types of information needed for assessing a number of different aspects. The main issue is to get the right information and presenting it in a way suitable for the target group. This is done in the case of Falk in Skanska (in Norway). It is a system gathering and presenting a multitude of KPIs, from a number of different systems, in an easy to understand layout.

    Vertikalarmering i tegelbalkar ur arbetsmiljöperspektiv2014Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    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.

    Situationsanpassat ledarskap för byggproduktion2013Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    A large cost at the construction sites today is the labour cost of the workers. But unfortunately the worker potential is not used to full. It is not unusual to take into a count with a work-­‐place-­‐additional-­‐time of 50% in some cases. By increasing the workers' motivation and responsibility for their tasks may reduce the time considerably, which also increases the potential for greater gains in construction projects.

    By using the situational leadership may the workers level of maturity develop entirely. They become broadly self-­‐propelled with high efficiency and the construction leader can after that get more time for his/hers own tasks.

    The work gets done more efficiently and the potential for greater profits increase. Good leadership at the construction site also improves the working environment for all. More people may be motivated to go to work and such sickness absence may decline.

    Abstract [en]

    The number of elderly in Sweden is increasing due to improved living conditions and better medical care. It is important that society adapts to the increase and begins to work preventively to reduce the costs of the increase. An important aspect is the elderly accommodation, the cost of health care in specific accommodation is almost twice as high as those for ordinary housing. Therefore, it is important that we availability adapt dwelling to allow older people to live in ordinary housing for as long as they wish, instead of moving to assisted living before they need it. If we can fulfil the elder’s needs with home care instead, society can save a lot of money.

    In this report, three different forms of housing has undergone accessibility increases and been inventoried and analysed. The result shows especially on major shortcomings in the real estate and site level. Many simple and inexpensive actions could be done to improve the sense of security and the availability.

    A degree thesis about quality control and assurance in construction. Made in cooperation with Wästbygg. An analysis was made of the self-monitoring control that is conducted during the construction. The data was collected from interviews from personnel employed by Wäsbygg as either work-leader, project-manager or quality- and environmental-coordinator. During the study there was also a review of the literature in the subject. From the data collected it was found that lack of commitment and poor attitude about the procedure were some of the main reasons why it doesn't work.

    To improve the self-monitoring control during construction is it necessary to execute it more consistently. Have clearer definitions for what self-monitoring control to make it easier for workers to conduct it. The workers also needs extra training and education in the subject to preform it better. The management on site does also need to participate more to show that it's a important procedure.

    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.

    This paper describes an attempt to include a course, “Innovation”, in an educational programme for construction engineers. This course has been divided into two parts; part 1 which is entirely theoretical, and part 2 which mainly consists of a project. The course has been given during six academic years and the response from the construction engineering student has been mainly positive. Some of the projects have resulted in feasible new products. The intention is to execute some research within the field “Innovation in Construction” with this course as a starting point.

    Adoption of a Working Environment Innovation: “Rollout Bar Carpets”2015Inngår i: Proceedings CIB W099 Belfast 2015 / [ed] Mike Behm & Ciaran McAleenan, Downpatrick: EEI Publishing , 2015, s. 417-425Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Work environment problems associated with reinforcement work at constructions sites are often great and difficult. This applies especially to the ergonomic situation. The situation is particularly difficult in connection with reinforcement in horizontal structural elements such as slabs and foundation slabs on the ground, where several of the most difficult load factors occur. Since about 15 years there is an innovation (rollout bar carpets) available on the Swedish market. This innovation can many times be used at these structural elements and gives both time savings and working environmental benefits. Despite this the innovation has been and is adopted rather seldom. The reasons for this have been studied through semi structured interviews with with design-engineers, site-managers, workers and persons working at a reinforcement manufacturing company. The main results from the study are as follows: i) Rollout bar carpets have a potential of improving both work environment and time consumption on site. However, this may not be enough in itself to achieve a general adoption of the technology. ii) The implementation and adoption of innovations in construction may be more complex than the novelty of the innovation may suggest. This is due to the contextual delimitations of a project-based industry and the different roles in the construction process.

    Success Factors Related to Industrialized Building in Sweden2014Inngår i: CIB International Conference 2014: W55/65/89/92/96/102/117 & TG72/74/81/83: Construction in a Changing World: Book of Abstracts / [ed] Dilanthi Amaratunga, Richard Haigh, Les Ruddock, Kaushal Keraminiyage, Udayangani Kulatunga & Chaminda Pathirage, Salford: School of the Built Environment, University of Salford , 2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    During the last decade there has been intense discussion in Sweden about industrialization in construction. The discussion has focused on industrialization in connection with erection of multi dwelling houses. It has been argued that industrialization is a key factor as regards obtaining affordable high-quality dwellings. During the last ten years some new industrialization concepts have been developed and tested. Even though some concepts have failed others have been more successful and are under further development. Industrialization is a reality within the Swedish construction sector and can be assumed to play an important role in the future as regards obtaining affordable high-quality dwellings. In this paper success factors related to four industrialized building concepts/methods are described and discussed. The review is based on available literature relating to each of the concepts/methods/producers, from which it was possible to ascertain success and failure factors.

    Introduction of sustainable low-cost housing. Experiences from a demonstration project viewed from an innovation diffusion perspective2016Inngår i: Proceedings of the CIB World Building Congress 2016: Volume V - Advancing Products and Services / [ed] Nebil Achour, Tampere: Tampere University of Technology, 2016, Vol. 5, s. 431-442Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The purpose of the study is to describe and analyse, from an innovation diffusion perspective, factors important when using demonstration projects as a tool for introduction of sustainable low cost housing. The study is focused on Ethiopia, a country with big challenges as regards population increase, lack of resources, deforestation, land erosion and a general need for better and sustainable housing, especially in rural areas. The study is furthermore focused on the adobe technology as a more sustainable alternative to the traditional building technology which is very timber consuming. Many attempts have been made to introduce this technology with the use of demonstration buildings. A great part of these attempts have failed, some have been successful. In order to study and discuss important factors in connection with the use of demonstration buildings, a project executed some years ago in southern Ethiopia has been analysed. The study is based on findings collected during and after the erection of these buildings mainly through practical tests, interviews and observations. From a technical point of view this demonstration project was successful. It was possible to develop an appropriate production technology and the result was buildings with a good standard and good function. Experiences up to now indicate a good durability. From an innovation diffusion perspective however the demonstration buildings have not fulfilled their purpose. The impact in the region seems to be very small. The conclusion in the paper is that the reasons behind this failure mainly are: (1) Lack of clear and visible relative advantage in comparison to the traditional building technology. The supply of construction timber in the area in question is still good. (2) Lack of a champion advocating the technology by using the demonstration buildings and thereby giving the message to the society that the technology is valuable and trustworthy. (3) Lack of continuity in the demonstration efforts, as a result of the lack of a champion.

    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.

    Inblandning av flygaska i betong - inverkan på tidig hållfasthetsutveckling vid låg temperatur2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Detta examensarbete har haft till syfte att undersöka utvecklingen av tryckhållfasthet vid låg

    temperatur hos betong med olika innehåll av flygaska. Tryckhållfastheten har bestämts genom

    provtryckning av kuber med åldrar upp till 28 dygn. Provningen har utförts på tre delserier;

    delserie 1 utan innehåll av flygaska, delserie 2 med 7,5 % och delserie 3 med 15% flygaska räknat

    på cementvikten. Kuber från dessa delserier har förvarats under olika temperaturförhållanden;

    från lägst ca 7 °C till höst ca 20 °C. Temperaturutvecklingen i representativa kuber har

    kontinuerligt registrerats. Tryckhålfastheten har bestäts efter 1 dygn, 2 dygn, 7 dygn och 28

    dygn.

    Resultaten frå de utföda mäningarna ä i huvudsak föjande: (i) Inblandning av 7,5 % flygaska ger

    en reduktion med 8,3 –11 % av hålfastheten vid hädning vid ca 20 °C och vid provning vid olika

    åder. Inget klart samband mellan provningsåder och reduktion. (ii) Inblandning av 15 % flygaska

    ger en reduktion med 22,1 –24,6 % av hålfastheten vid hädning vid ca 20 °C och vid provning vid

    olika åder. Inget klart samband mellan provningsåder och reduktion.

    Pågrund av svåigheter att styra temperaturen hos provkropparna påett noggrant sät visade det

    sig svåt att dra sära slutsatser avseende inverkan av säkt hädningstemperatur. Föjande kan

    dock sköjas i de uppmäta resultaten. (i) Inverkan av reducerad hädningstemperatur minskar

    med öande åder. Detta gäler oavsett halten av flygaska. (ii) Lå temperatur i tidigt skede (de 7

    fösta dygnen) ger en föhöd sluthålfasthet. Detta gäler oavsett halten av flygaska.

    Fö de olika kuberna som provtryckts har den ekvivalenta mognadsådern beränats med hjäp av

    uppmäta temperaturer. Detta har gjorts dels med TT-faktormetoden, dels med hjäp av

    Ahrreniusfunktionen. Baserat pådetta har teoretiska hålfasthetsutvecklingsfunktioner formulerats

    fö de tre serierna. Genom dessa funktioner har inverkan av flygaska och temperatur kunnat

    analyseras. Dessa analyser tyder påföjande: (i) En inblandning av 7,5 % flygaska ger en reduktion

    av den relativa hålfastheten med 5 –10 %. En minskande temperatur och en minskande åder ger

    minskande inverkan. (ii) En inblandning av 15 % flygaska ger en reduktion av den relativa

    hålfastheten med ca 20 %. Detta gäler oavsett åder och temperaturnivå

    Flervåningshus av trähusmoduler: Kostnadspåverkan på trähusmoduler till följd av ökade krav per våning2019Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    For more than a decade the construction of multi-storey wooden houses with more than two storeys was banned in Sweden. In 1994, regulations became function-based and multi-storey wooden houses was allowed once again. Due to the long ban, there is a lack of knowledge regarding multi-storey wooden houses. Despite this lack of knowledge there are still advantages with wooden houses, including the non-existing drying times and low weight, resulting in reduced transport and production times. In the case of wooden modules, the competitiveness increases with these reduced times, however, the technical solutions and needed material changes with the different regulations at different levels, thus affects the costs of modules.

    This study aims to show the change in cost of material and competitiveness due to the different regulations. The study is based of Swedish conditions and interviews with Swedish companies that work with wooden modules.

    Results of the study shows that the competitiveness of wooden modules mostly is affected by the change of fire restrictions and acoustics. With the use of modules, solutions such as savings in foundations is enabled. One conclusion of the study is that construction, production, transport times and environmental aspects impacts the competitiveness most. This enables modules to reduce the price by 10-15% in cases that require few detailed and architectural solutions compared to other construction alternatives.

    BIM Inertia: Contracts & Behaviours2015Inngår i: Building Information Modeling: Applications and Practices / [ed] Raja R. A. Issa & Svetlana Olbina, Reston, Virginia: American Society of Civil Engineers (ASCE), 2015, s. 107-134Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    Whilst Building Information Modelling (BIM) promises significant improvements in construction quality and efficiency, current contractual models do not encourage its use; indeed actively inhibit the collaboration at its core. To help bring BIM into the mainstream, it is claimed we need to re-craft existing contractual relationships to facilitate collaborative decision making and to equitably allocate responsibility among construction participants. This chapter looks at the case of Sweden and aims to identify and appraise observed hindrances to BIM collaboration and digital information stewardship. It presents an understanding of the connections between the commercial environment and contractual provisions that regulate the party’s business relationships and the resultant procedural and behavioural phenomena that can be viewed to thwart BIM collaboration and degrade the value or integrity of digital deliverables. The study then, in a more general context, asks what we can learn here that may have wider application through consideration of suitable BIM collaboration support mechanisms that may reduce or remove collaboration barriers, induce open, sharing behaviours and support the creators and users of digital information. Methods employed include a critical review of existing contract forms, synthesized with focus group interviews (FGIs) with representatives from diverse AEC disciplines. Results indicate that a number of systemic difficulties exist that can create an inertia which can be traced through behaviours and circumstances to contractual provisions. An understanding of such difficulties is presented and a consensus emerges on a number of key supporting mechanisms that may better facilitate meaningful early BIM collaboration and oil the wheels of communication without recourse to re-writing the rule-book.

    National and International Benchmarking: CREDIT Report 52010Rapport (Annet vitenskapelig)
    Abstract [en]

    This report summarizes findings and recommendations from 24 case studies from seven participating countries addressing performance indicator benchmarking at a sectoral, national or international scale. Their distribution in scope is: – benchmarking systems and indicators (4 case studies) – offices (7 case studies) – housing (6 case studies) – school and nursery (4 case studies) – shopping centres (3 case studies). In addition, actual performance benchmarking was done between six Finnish and Norwegian office buildings using CREDIT Key Performance Indicators and a web-based benchmarking tool, developed in CREDIT for that purpose. Some good benchmarking practices exist already at a national and international level. They focus on process issues, investment aspects and environmental properties. These existing schemes contribute to the CREDIT framework, but don't cover well the performance dimension. There isn't yet any commonly agreed European Key Performance Indicator system, or building and real estate performance indicator standard. CREDIT made a contribution to their development from the Nordic/Baltic perspective. It also provided valuable input from the performance and social sustainability point of view to existing economic and environmental oriented schemes that are continuously updated and amended. CREDIT made progress in performance indicator framework and actual performance indicators and tools, some of which were already tested in the case studies. Understanding on existing benchmarking schemes is also improved. The results of CREDIT WP6 performance indicator benchmarking at a sectoral, national or international scale can be exploited in number of ways, such as – the front runner companies adopt the core performance indicators in their practices and influence in forming their use a sector based practice – further development of standardization, tool development (IFCs), benchmarking schemes and rating systems makes use of the results.
