Lindén, Anna, and Peter Dehlin. "BIM i planeringsarbetet : Effective planning by using BIM." Thesis, Tekniska Högskolan, Högskolan i Jönköping, JTH, Byggnadsteknik, 2012. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-19131.
Full textSammanfattning Vikten av god produktionsplanering ligger till grund för dels den ekonomiska produktionskostnaden, dels tidsaspekten i projektet. Som bakgrund till rapporten har planering i byggproduktionen studerats med syftet att kartlägga hur treveckorsplaneringen ser ut inom bygg- och anläggningsbranschen i dagsläget. En fallstudie har genomförts i Navisworks Simulate för att undersöka om programvaran lämpar sig att sammankoppla treveckorsplanering med BIM-modell för att skapa en 4D-modell. 4D-modellen används för att på ett tydligt vis visualisera arbetet i projektet. För att utnyttja modellen krävs investeringar i utrustning och programvaror vilket innebär dyra kostnader för företagen. För visualisering av projektet eftersträvas därför en programvara till låg kostnad så att det ska bli lönsamt att använda 4D-modellen i produktionen även på mindre projekt. Den utredning som genomförts med syftet att kartlägga planeringsarbetet inom bygg- och anläggningsbranschen visar att planeringsarbetet varierar dels mellan bygg- och anläggningsprojekt men även att planeringsteknik beror på kunskapssnivå hos den som ska genomföra planeringsarbetet. Slutsatsen är att utbildning i planeringsteknik och datorstödda planeringsverktyg behövs för att kunna implementera BIM i planeringsarbetet. Med en detaljerad tidsplanering och produktionsanpassad projektering är Navisworks Simulate ett utmärkt program att använda vid skapandet av BIM-modeller. Vid användandet av Navisworks Simulate för skapande av 4D-modellen är Navisworks Freedom det naturliga valet av program för visualisering ute på arbetsplatsen i produktionen. Detta beror på att Navisworks skapar sitt eget filformat, vilket endast går att öppna i programvaror från Autodesk. Slutsatsen blir att valet av programvara för skapandet av en 4D-modell påverkar vilka program som senare kan användas för visualisering. Examensrapporten syftar till att förbättra treveckorsplaneringen, samt att öka utnyttjandet av erfarenhetsåterföringen inom produktionen genom användande av CAD-samordning och BIM.

Full textClarus Arkitekter as design companies often receive orders from contractors and clients asking for a BIM model. In most cases, the BIM model is not fully used, but 3D drawings or 2D drawings are available. Then asks the question "Does the client / contractor have the correct understanding of what BIM is?" Different players have different guidelines and requirements that the projector should follow, which can be perceived as defective by the projector just to know what is demanded from each client. The question the thesis will answer is "How should the consultant do the best to offer the right service and what goals the consultant will do. The purpose of this master thesis is to find out how BIM usage could facilitate the work as well as the communication between the various actors who is involved in a construction project. To investigate how the level of competence lies with the Client, Entrepreneur and Projectors / Architects and answerthe question "what is behind the skill difference that exists?". The work began with literature studies for the collection and compilation of information. Questions will be set up to later use them during interviews with different people from different companies. The interviews will take place with individuals from consultancy, contractor and client company. The interest in using BIM is high in the industry, but unfortunately there is a great deal of skills shortage. Customers and entrepreneurs plan to start using BIM more, which will happen in the coming years, but now, they do not want to take new risks and prefer to use traditional methods that are more secure. To be able to apply BIM more in the construction industry, more knowledge is needed.

Full textIs the new technology always the best? This final project tries to determine if BIM is the melody of today, or if traditional 2D drawing is recommended. Perhaps a compromise is necessary, utilizing both methods.
In order to answer this question, different views from the industry have been retrieved through reports, producers of software and users. The approach has consisted in building a 3D model of the school Råslättsskolan, house 01, along with interviews with people involved in the building process.
When working in 2D it is hard to include the third dimension, mistakes are done and collisions happen that must be corrected, in most cases at the construction site. BIM is an incredible help since the model allows you to detect collisions and correct them. Another time when models are preferred is when you need production plans, for example, different steel details that will be joined together at the work shop before shipping to the construction site.
Skanska and NCC, in densely developed urban areas, already require BIM today, something that most likely will be customary within the nearest future. It is not hard to understand that more and more clients require BIM when you realize its advantages. With the correct method, these 3D models can minimize risks of errors, optimize the production and save money.When it comes to introducing BIM today at BGK the students can’t do anything but make a recommendation. The improved quality, the future prospect and that the advantages of BIM is not depending by project size will make it attractive for BGK to begin a transition already today. BIM is the melody of the future, not the only song being sung, but clearly the strongest one.

Full textBuilding Information Modeling is a step in the right path to be able to handle the production rate that is needed for the increase in population in Sweden and handle the current housing shortage. It is important that the small and medium sized enterprises follow the extensive digitization which is happening to the construction sector, and it is also essential to keep being competitive in both Sweden and Europe. Increase Competence in Northern Building is a project which started to make sure the small and medium sized enterprises from the Nordic countries keep being competitive in Europe. ICNB is an interregional project together with Norway and Finland. Building Information Modeling refers to the process of handling information regarding a buildings whole life cycle or parts of it. There are plenty of benefits from using BIM, and it is also one of the biggest reasons that it is important to follow this digitization to keep being competitive in Europe. Through interviews with different trade organizations and a couple of companies from each industry branch will competence and experience for BIM be investigated. The results show that the companies agree on the positive aspects with usage of BIM. It varies a lot between NCC and the consulting companies what focus the educations have, where the main purpose with the educations is the biggest difference between them. The consulting companies educate purely to be able to use the software practically, where NCC also works with developing the mind-set and understanding for BIM.

Full textThe purpose of this report is to enable project management and construction personnel to use BIM tools and methods more efficiently. Although NCC is currently using some functionality of such digital tools, NCC is not using the full tool suite to better manage their projects, specifically to leverage the cross discipline collaboration capabilities. In order to gather a comprehensive view of construction personnel requirements, interviews were conducted across a varied and wide range of age, seniority, and job position. These interviews formed the basis for the evaluation criteria of the BIM tools. Additional interviews were held with other staff, including project leads, model coordinators and construction engineers to ensure their knowledge was incorporated into the evaluation. To compliment the interviews, and further evaluate the digital tools for cross collaboration capabilities a house was modeled in Tekla Structures and Revit. Also the architectural and construction models of NCC project Trollhättan 33, T33, was available for testing. Two programs emerged as ‘best in class’ post the assessment, differentiated primarily by which phase of the construction lifecycle they were used for. Solibri Model Checker, SMC was considered most suitable tool in the project management phase and Trimble Connect considered best during the construction phase. SMC is suited for validation and quality control and Trimble Connect is a tool, in which models and documents can be stored for easy collaboration in project teams as well as visualizing models, which are easily shared via computer, tablet or mobile phone. The following BIM tools were tested: Solibri Model Checker v9.6 Navisworks Manage 2016 Autodesk BIM 360 Glue Trimble Tekla BIMsight Trimble Connect

Full textFor 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.
I snart 20 år har man pratat om Produktmodeller men i byggbranschen är det svårt att införa nya arbetsmetoder. Produktmodeller har senare fått namnet Building Information Modeling eller Byggnadsinformationsmodeller på svenska, fortsättningsvis kallat BIM. Många säger idag att de BIM:ar när de gör 3D modeller men de glömmer ofta den viktigaste delen, informationen. Till 3D modellen kan egenskaper och information kopplas till varje objekt. Information som sedan kan vara ovärderlig för förvaltaren.
Vi har en vision av att i de bästa av världar skall förvaltaren kunna ”gå” in i modellen och se vad för installationer som finns i t.ex. väggar och ovanför takplattor. Dessutom ska man bara kunna peka på ett don och få all information om det vad gäller drift och underhåll samt produktnamn och artikelnummer för att köpa ett nytt. Därför försöker vi i examensarbetet lyfta fram förvaltaren och fördelarna för denne.
För att få ut det bästa med BIM krävs samordning. De olika aktörerna i processen måste börja arbeta tillsammans i ett tidigt stadium, d.v.s. vara med och påverka redan i utredningsstadiet. Kan man ha med förvaltningen redan i utredningen får övriga aktörer en bättre förståelse för vad som förväntas av dem. Samtidigt kan förvaltningen tidigt få veta om några krav är orimliga eller svårlösta.Projektering måste få kosta. Ett väl projekterat projekt kan senare spara massor med pengar på att inga problem behöver lösas på byggarbetsplatsen. I väl projekterade projekt minskar ÄTA-arbeten och kollisioner. Nyckelorden för detta är Samordning och Samgranskning.
I förvaltningsskedet finns det stora utsikter att spara kostnader med hjälp av BIM, fördelarna har börjat visa sig och en del större förvaltare har börjat ställa krav på en produktmodell som går vidare in i förvaltningsskedet. De största fördelarna är bl.a. visualiseringen som ger en bättre förståelse och ett bättre underlag för beslut, effektiviseringen som spar både tid och material, kvalitetshöjning och bättre dokumentation för underhåll, drift, uthyrning, framtida ombyggnad och framtida försäljning.
För att skapa oss en bild om BIM, hur det används idag och vilka förväntningar som finns branschen, har vi intervjuat förvaltare, systemansvariga och BIM-experter. Vi har även sökt information i rapporter och tidsskrifter.

Full textI dagens samhälle ökar kraven på kvalité och effektivitet till en låg kostnad ständigt och alltfler företag väljer att satsa på nya metoder för att uppnå dessa punkter. De företag som lyckas hitta metoder som förbättrar deras processer har oftast störst chans att bli en vinnande aktör på marknaden. BIM är en ny metod som kan sänka de interna kostnaderna samtidigt ökar kommunikationen mellan olika parter. Det råder dock skilda meningar om vad syftet med BIM är, samtidigt som det finns flera olika tolkningar av det. BIM är ett nytt begrepp i byggbranschen och definieras som ett samlingsprogram med olika hjälpmedel som används i projektering, produktion och slutligen i förvaltningen. Det innehåller objektorienterade modeller som ska innehålla information om byggnaden under byggprocessen. Syftet med detta arbete är att hitta orsakerna till varför BIM används i en begränsad utsträckning samt redogöra vad som krävs för en utökad användning inom produktionen. Resultatet är baserad på intervjuer av produktionspersonal från olika företag men även litteraturstudier. Slutsatsen vi kommit fram till är att BIM förbättrar arbetsprocesserna i branschen. Precis som all ny teknik och förändringar möter BIM motstånd av olika anledningar. Dessa kan vara bristande kunskap, rädsla för förändringar och oklarheter kring tekniken.

Full textThe purpose of this study is to improve the flow of information from the design and construction phase into the facility management. This in order to make the facility managers see the advantages with BIM and to show that there is money to be saved by retrieving the information from the design and the construction phase. Earlier studies show that there actually has been quite little research done within BIM in the facility management and that the main focus has been at the design and the construction phase. The aim with the study is to specify the value of the information and to show which information facility managers use and where it can be retrieved from within the earlier phases of the construction process. The report is based on a literature study, interviews and calculations. A number of facility managers have been asked which types of information they use and designers and entrepreneurs have then been asked if these types of information can be found in the design and the construction phase. The information has been valued in two different ways. In one way the information was valued by comparing the cost between updating existing information or recreate the same type of information. The other way of valuing the information was to find out the worth of information by using key figures (SEK per square meter) and the list of information that facility managers use, which was made up from the interviews. The first way of valuing shows that the cost of producing as built drawings (A) in the facility management cost as much as keeping the same type of information updated for at least 18years and as most 50years. Almost the same goes for a BIM-model. Only there the difference is that the cost of producing a BIM-model focused on as built drawings (A) in the facility management cost as much as keeping the same type of information updated for at least 22years and as most 58years. The other way that the information was valued shows that less than 25% of the information that can be found in the design and/or construction phase is worth circa 10% of the projecting fee.

Full textDetta examensarbete handlar om byggnadsinformationsmodellering, BIM, i produktionen. Kort förklarat är BIM en virtuell modell av ett byggobjekt, där all information som rör byggnaden samlas. Alla aktörer i ett byggprojekt har tillgång till denna modell och kan, genom denna, samla in eller dela ut information som rör objektet. Det finns olika tillämpningar av BIM i produktionen, denna studie behandlar främst visualisering, arbetsberedning och planering, mängdavtagning och samordning och kollisionskontroller. Grundproblematiken lyftes fram med hjälp av uppdragsgivaren Byggdialog AB. Företaget har en vision om hur BIM ska användas i byggprocessens olika skeden. Byggdialog upplever att deras partneringentreprenörer, PE, bör utveckla sin BIManvändning i produktionen för att denna vision ska kunna uppfyllas. Goodtech är en av Byggdialogs partneringentreprenörer och är det företag som studerats i detta examensarbete. Målet med arbetet var att, med utgångspunkt från teorier samt Byggdialogs vision, ge förslag till hur partneringentreprenören kan utveckla BIM-användningen i produktionen. Syftet var att få partneringentreprenören att förstå nyttan med att använda BIM i produktionsskedet. Avsikten har också varit att andra partneringentreprenörer ska ha nytta av denna studie vid användning av BIM i produktionen. De metoder som användes var studiebesök, litteraturstudie och intervjustudie. Intervjuobjekten representerade olika yrkeskategorier som alla kan påverka användningen av BIM i produktionen. Detta examensarbete resulterade i konkreta förslag till hur partneringentreprenören kan förbättra BIM användningen. Även förslag till hur Byggdialog kan säkerställa att deras PE använder BIM korrekt togs fram. Idag använder partneringentreprenören BIM främst för att visualisera byggobjektet. Förslagsvis bör de även använda BIM vid arbetsberedning/planering av arbetet. Partneringentreprenören har också förutsättningar för mängdavtagning ur modellen. För att möjliggöra dessa tillämpningar är det viktigt att partneringentreprenören förstår hur 3D - modellen kan användas, samt vilken information som finns i den. Det är även viktigt att modellen är noggrant projekterad. Förslag till hur detta kan uppnås är genom att partneringentreprenören utbildar sig inom BIM och hur det används, att de deltar i BIM-samordningsmötena samt att de ställer högre krav på sin elprojektör. Byggdialog kan säkerställa att deras PE använder BIM korrekt genom att erbjuda utbildningstillfällen, anpassa BIM-modellen efter användaren och ställa krav i förfrågningsunderlaget.

Full textThe AEC industry is in the midst of a paradigm shift - this in conjunction with BIM replacing traditional working methods within the construction process. BIM, also called object-oriented information management, is currently used for 3D modeling, visualization and coordination. However BIM is not being utilized to its full potential. There are also occurring changes regarding the environmental aspects of construction. Environmental requirements are not only legal, but are now requested by the clients themselves. One reason for these changes is increased environmental awareness and another is the fact that the construction industry has a vital role in sustainable development. Environmental certification of building projects promotes an environmentally friendly production. ‟Miljöbyggnad” is one of the most common certifications in Sweden because it is adapted to the Swedish building regulations. One of the assessment criteria for ‟Miljöbyggnad” is the logbook documentation of all the building materials used. It is the contractor who is responsible for the logbook and for the environmental building certification during the production. This thesis investigates how logbook management for environmental certification can be efficient and optimized in the context of BIM. The first stage of the thesis was devoted to the identification of problems related to logbook management. This was done with the use of surveys and complementary interviews. In the second phase BIM experts were interviewed in order to find practical applications for BIM in the log management process. The survey revealed several areas of concern within current logbook management. However these problems can be resolved if construction companies can establish a consistent work methodology, define the logbook procedures and implement experience feedback. Analysis of the interviews resulted in suggestions for possible streamlining of logbook procedures using BIM –one solution which is possible to implement today and three for future use. The solution which has been named "Excel list with GUID" can be applied today. Here, the BIM model generated during the design stage, is used to streamline the logbook process with the help of unique reference numbers. Automatic quantity take off for construction products is an example of a streamlined logbook process. Three solutions are possible for future material documentation in BIM: An application, integrated computing platforms or a company shared database. In the future results can be considerably improved with an automated logbook process. The logbook within the BIM model creates the opportunity for traceability and visualization. It eliminates costly and time-consuming steps in comparison with todays logbook management. The conclusion is that construction companies should invest in a company-wide database for all computing platforms, but the future of material documentation with BIM exists in an integrated solution with the BIM model and a PLM system.

Full textDet kommer hela tiden ny teknik. Inom byggbranschen pågår det en utveckling för att hitta arbetssätt som kan utnyttja dessa moderna tekniska lösningar. Begreppet BIM står för denna utveckling av informationshantering och handlar alltså om att effektivisera och förbättra byggprocessen. Många inom byggbranschen vet fortfarande inte vad begreppet står för och därför inte heller vad det innebär att arbeta med verktygen. Att upprätta en bra planering är en viktig förutsättning för kunna utföra ett lyckat projekt. Idag används det olika sätt för att upprätta planeringar inom byggbranschen men det är oftast traditionella metoder där resultatet presenteras i ett Ganttschema. Men det finns andra sätt och ett av dessa är Flowline som användes redan när Empire State Building byggdes. Ett program som använder sig av Flowline och även påstår sig falla under begreppet BIM-verktyg är Vico Office. De påstår att arbetssättet som används i deras program kan effektivisera tidplanen med 10-20 %. Som det tidigare nämns vet många inte vad det innebär att använda denna typ av verktyg och inte heller metoden Flowline och därför vill Skanska utreda den frågan. Syftet med studien är därför att ge läsaren kunskap om vad det innebär att planera med Vico Office samt att undersöka programmets flexibilitet gällande förändringar i 3D- modellen och planering. Planeringen utgick från en 3D-modell för Skanskaprojektet Länsförsäkringar i Umeå. Samtidigt testades programmets flexibilitet genom att uppdatera till nya versioner av modellen och genom att förändra hur byggnaden delas upp vid uppförandet. Allt detta för att resultera i en beskrivning av vad det har inneburit att genomföra arbetet. Beskrivningen visar att ett uppförande av en planering i programmet med en tidsplanspresentation i Flowline kräver att en rad olika moment genomförs. Några av dessa är kontroll av modellen, upprättande av kalkyl, mängdavtagning, upprättning av aktivitetslista, koppling av de olika delarna till varandra, platsindelning av byggnaden och bearbetning av tidplan i Flowline. Studien visar på att det finns fördelar med att använda den här typen av tekniska lösningar vid en planering utav ett byggprojekt. Det är fördelar som exempelvis en smidig platsindelning och en visuellt stark presentation med hjälp av Flowline. Det finns också ett flertal aspekter som det krävs att man tar hänsyn till för att säkerställa metodens framgång. Utöver studien behandlar Vico Office många fler funktioner som har samband med planeringen vilket kan göra att programmet i sin helhet blir mera fördelaktigt att använda. Vid upprättandet krävs det att modellen som används till bas för planeringen är anpassad och väl utvecklad. För att slippa göra om arbetet, som i vissa fall kan vara omfattande, krävs det därför att projekteringen och modellen tidigt är långt framgången. En risk med en planering som till stora delar utförs genom att hämta information från en modell är att engagemanget hos de som ska utföra arbetet minskar. Det är farligt då det är en av de viktigaste framgångsfaktorerna vid planering. Något som inte heller får glömmas är att erfarenhet och kunskap hos planerarna är väldigt viktiga aspekter för att planeringen ska bli lyckad. För det spelar ingen roll hur bra en tidplan är om det inte följs och det gäller därför att hitta bra arbetssätt som både involverar, utnyttjar erfarenheter och nya tekniska hjälpmedel.

Full textAbstract Purpose: The main problem with implementation of BIM within calculation is the weaknesses and inaccuracies in 3D-models that makes them unreliable. The aim of this work is therefore to clarify how the information quality in a BIM model can be improved to thereby increase the use of BIM within calculation of construction companies. Method: Interviews, observation studies and literature studies are the chosen methods to answer the questions in the report. Interviews were conducted with companies that have implemented BIM within calculation, with those who have not introduced it yet, and with those who are about to implement it. Observation studies were conducted with the supervisor company where the calculation process was clearly reported. Literature studies have been done throughout the course to have a theoretical knowledge of the whole. The information from these three methods has then been compared to therefore make good conclusions. Findings: A guidance to the industry as a solution to quality problems in models is to set up manuals. These will be used during the creation of the models which will probably lead to a reduction of errors. However, it also requires experience and skills in staff as well as investments on cost and time. Implications: If the implementation of BIM within calculation succeeds, it will be possible to make safer calculations that strengthen the company's competitiveness. By implementing this as early as possible, companies can develop and avoid falling behind in the industry. This benefits both the company and the new technology while achieving great time and cost savings. An implementation like this can be successful in establishing manuals with clear requirement specifications which are applied during the creation of a model. This can be done with right experience and skills in the involved staff. Limitations: The limitations in the results are among other things, the fact that construction contracts and allocation of responsibilities are not included. In addition, it is limited to treat BIM in early calculation phases, which means that BIM in planning, production, management and other stages are excluded. Keywords: BIM, 5D, benefits, costs, manuals.

Full textDespite the opportunities and benefits that the digitalization brings to the construction processdifferent stages, there are many participants in the construction sector who performs their bidcalculation using a traditional method. The traditional working method is considered timeconsuming and imprecise. There has been a development in the construction industry fromproducing digital 2D drawings to creating 3D models which is associated with informationabout each included building component. These 3D models are called building informationmodels or BIM models and are used for, among other things, bid calculation purposes. BIMmodels entails the bidding calculations great advantages. Therefore, it is Interesting that thismodern and digitized working method are not used by many participants today.This study aims to investigate whether BIM can contribute to an improved bid calculation. Thestudy also aims to identify which factors prevent the implementation of BIM in the bidcalculation. The purpose of the study is achieved by responding to the three questions of thestudy. These three questions handle the advantages of BIM in bid calculation and differencesin the results of calculation by each method. The study's questions also handle the requirementsthat are set on the used BIM model for bid calculation.The result and conclusion of the study is that BIM streamlines the work on bid calculation,increases the precision of the quotation and contributes to a better understanding of what havebeen calculated. BIM also facilitates communication between the participants and provides theopportunity to reuse the bid calculation in the later stages of the construction process. Therequirements set on the BIM model are how detailed the model should be created and thedesignation and classification of the objects. The BIM-model should also be correctly drawn,the included objects are correctly placed and with the right amount. What prevents theimplementation of BIM in the bid calculation are participants who are comfortable with thetraditional working method and have a lack of skills within BIM. Another factor that preventsthe implementation of BIM in the bid calculation is that there are no standard agreementsadapted to a BIM model. Which makes it difficult to resolve any disputes that may arisebetween the entrepreneur and the client.

Full textThe report has a focus on Building Information Models (BIM), an IT-technical tool- and workmethod that have emerged increasingly in the construction industry in recent years. How this IT tool is used in medium-sized building construction companies is presented in this report.The purpose of the report is to promote positive development towards more efficient and resource-efficient work processes in the construction industry by providing knowledge on how the use of BIM exists among these companies, why it is the way it is, if BIM is needed and what can change the current status in any direction.The work-method has consisted of literature studies and interview surveys.The work began with studies of reports and texts related to BIM and interviews with representatives of leading construction industry companies and a couple of industry organizations with focus on BIM. This was followed by continued literary studies focused on change and change management, survey and interview techniques. This work led to various basic theories and explanatory models as the basis for and the design of the interview questions asked at the main interviews.The main interviews was conducted with eleven medium-sized building construction companies and gave a result that showed that companies generally looked at BIM as something positive with advantages such as easier communication and as a means to reduce errors in production. The result also brought some light to the fact that there existed challenges like software compatibility and dependency between the parties involved in the project, which means that for the technology to be able to provide wanted benefits all parties involved have to use the workmethod.The reasons for the low usage among medium sized construction contractors was several, the most common was the lack of demands of the clients. The reasons were also the absence of need, costly investments, competing objectives, compatibility issues with software and lack of knowledge of BIM.In order to promote a greater usage of BIM it is proposed that the technical obstacles are eliminated through standardization and development of the processing method and software, it is also proposed that the competing objectives are eliminated by spreading and increasing knowledge of BIM in the industry, both amongst entrepreneurs, -to promote good staff training so that the staff will want to work with the technology, and amongst construction clients, -so that they start asking for BIM and thereby provide the technology with a competitive edge.

Full textPurpose: The shortcomings of information transfer between the different building phases has a negative impact on facility management (FM). Because of the complex information needs it is important that the FM specifies which information they want delivered from the design and construction phases. The negative impact can be reduced with BIM because of its ability to ease communication between the disciplines. Therefore, the aim of the thesis is to ease the implementation of BIM within the technical FM of the public sector, and following questions are asked: (1) What does the process of operation and maintenance in a technical department of FM in a public sector look like? (2) Which information is needed in this process, to effectively accomplish the FM activities? (3) How can you, with BIM, provide this information? (4) How should you do to succeed with the implementation of BIM in FM? Method: The approach of the thesis is a case study, studying the technical department of a public FM. All questions are based on each other, which means that the data collection and the analysis have been done in interaction. Mostly, the questions have been answered by literature studies and interviews, but observations and document analysis has also been done. Findings: The result of the first question shows that the process of operation and maintenance is complex and includes many different disciplines. The process includes an administrative part where actions and intervals are connected to the installations in the FM system. The process also includes that the maintenance personnel performs the actions, and if problems occur, the technical manager and the operating engineer are being consulted for a solution. The result of question 2 shows a big need of different information. The information needed by the most people are; placement, the installation’s component and manufacturer/supplier. Although some information might not be needed by a lot of people, it is important to point out that the information does not have lower value. The result of the third question shows that the information that emerged from question 2 could be provided with BIM by connecting the information to an object through property sets, databases or portals. The result of the fourth question shows the way to implement BIM in FM; process mapping, information analysis and connect the information. Implications: The study shows that there are good opportunities to use BIM to provide relevant information needed by the FM. It is important to analyse the processes and information needs within the organisation. The implementation should be done in connection to a new construction or a reconstruction. Limitations: The study only observes operation and maintenance within the technical department of FM and does not investigate either economical nor technical aspects. The result is considered to be generally valid, however, a more complete result can be achieved with a bigger research of the FM organisation and several interview respondents.

Full textDeviations in a construction project lead to delays. They can also lead to prematurely completed activities. In any case, this will be a problem since the contract period for subcontractors is determined. What this means is that if a subcontractor completes its task prematurely, there will be a time buffer in the timetable between completed and next activity. This is considered a cost because no work is being done. If a subcontractor completes an activity late, this is also problematic as it displaces activities on the critical line. If the activities are on the critical line. It should be clarified that more types of deviations exist. Including delivery, delayed transport, unforeseen obstructions during production, etc. One method of avoiding deviations is to continuously monitor production activities using quantity take-off graphs. These graphs are charts showing built-up amount per unit of time and cumulative built-up amount. They give a visual picture of the state of production, and from there, decisions can be made about changes in production so that the project will follow the time schedule again. Quantity take-off charts come in three forms. Planned, actual & forecast quantity take-off graphs. The purpose of this degree project is to investigate how BIM tools during design phase can support a project under production phase by predicting deviations. If deviations are early discovered, resources can be adjusted or working hours changed to complete the project according to time schedule. The study shows that the quantity graphs can be developed relatively easily, but well thought out planning and structure are required. It is recommended to coordinate a good working method for the entire work from start to finish by having a coordinator who controls the model but also other officials who know the program well enough to support and relieve the coordinator if necessary. The study also shows that it is important that model developers deliver the model with a good and structured designation of object. This is easier to connect KPI-numbers to the correct quantity takeoff graph. CoClass classification system (project name BSAB 2.0) should be used as the basis for naming of objects.

Full textDe senaste 60 åren har många industrier haft en exponentiell utveckling gällande digitalisering och de har anpassat sig snabbt utifrån teknologins kapacitet. Däremot har byggindustrin haft en linjär, nästan oföränderlig resa genom åren. Det förekommer arkitekter och andra konsulter i branschen som arbetar uteslutande med 2D-ritningar än idag. Det är först under de senaste tio åren som 3D-modeller har börjat användas som metod för att ta fram ritningar, men standarden idag är fortfarande att byggnader produceras utifrån 2D-ritningar. Det finns stora utvecklingsmöjligheter inom byggbranschen, men få har lyckats utnyttja det maximalt eftersom de begränsas av yttre faktorer. Användandet av Building Information Modeling (BIM) behöver standardiseras i byggbranschen. Ett första steg till att ta del av den stora belöning som finns att hämta av digitaliseringen är att implementera BIM i hela byggprocessen. Syftet med examensarbetet är att undersöka vilka mervärden som erhålls när BIM implementeras i byggproduktionen. Examensarbetet redogör för byggprocessen och tillämpningen av BIM, samt redovisar erhållna resultat utifrån en kvalitativ studie där svaren från intervjustudien kan styrkas av litteraturstudien. I intervjustudien har fem respondenter deltagit och deras erfarenheter har tolkats och sammanfattats i ett resultat. Studien visar att det finns många mervärden från implementering av BIM i produktionen. Sammanfattningsvis är dessa: bättre informationshantering, ökad kommunikation, effektivare planering, minskade kostnader och ökad kvalitet. Resultatet av den undersökta frågeställningen visar även att ett erhållet mervärde i sin tur ger upphov till ytterligare mervärden. Slutsatsen är att för att kunna ta del av de mervärden som implementering av BIM i byggproduktionen medför, måste en investering i kompetens och resurser genomföras. Det behöver även ställas högre krav på myndigheter för att en digitalisering i branschen ska bli en standard eftersom det är först då stora förändringar kan börja utföras. Det finns stora möjligheter för byggbranschen att automatiseras i framtiden, och vidare kan det spekuleras i om det även kommer kunna leda till robotisering av branschen, 3D-utskrifter av byggnader och användning av AI för att utforma byggnader. Byggbranschens första steg i den framtida utvecklingen är att standardisera användandet av BIM i hela byggprocessen.

Full textThe aim of this thesis was to investigate the role of the pro-apoptotic BH3-only protein Bim, at the endoplasmic reticulum (ER) and the mitochondria. For this purpose, a full length human myc-tagged Bim cDNA was cloned into an adenoviral vector, which allows for the conditional expression of the transgene under the control of a Tet-Off-system. Two different Bim isoforms were used for these investigations. One was BimL, which is bound to the motor dynein complex of the microtubule and the other one was BimS, which is localized in the cytosol. The enforced expression of each of these two isoforms in the prostate cancer cell line DU145, showed the capability of BimL and BimS to induce apoptosis via either Bak or Bax. Also, Bax- and Bak-dependent breakdown of the mitochondrial membrane potential upon overexpression of either Bim isoforms was measured. This effect was also observed in cells overexpression the anti-apoptotic protein Bcl-2 at the ER. However, targeting Bcl-2 to the mitochondria partially inhibited Bim-induced mitochondrial permeabilization. These findings indicated the execution of the intrinsic apoptotic pathway upon Bim signalling. Nevertheless, expression of Bcl-2 at the mitochondria partially suppressed Bim-induced apoptosis whereas ER-targeted Bcl-2 entirely prevented cell death induction by Bim underlining the importance of the ER. Further, an upregulation of ER stress proteins upon Bim expression was seen. Cytochrome c release form the mitochondria and activation of caspase-9, -3 and -8 was observed. In addition, the complete inhibition of Bim-induced cell death by a pan caspase inhibitor revealed that caspases are crucial. In conclusion, Bim induces the mitochondrial apoptotic pathway and, in parallel, triggers ER stress. It seems that Bim mediates cell death through the interaction of the mitochondria and the ER. The ER-mitochondria cross-talk leads to the amplification of the apoptotic death signal.

Full textA construction project contains four stages, feasibility study, design, production and management. The planning stage is the entire design process where drawings and descriptions are created in order to be able to build and manage the intended building. The design stage consists of several different actors and technology disciplines where coordination and coordination are required. A tool that is used throughout the construction process but above all in the design is BIM, which is a work process that streamlines information management by gathering information into a 3D model during the construction project. BIM at the design stage consists of several different technology disciplines that need to be coordinated and coordinated to common goals so that misunderstandings do not occur and that important information is lost.This study investigates BIM manuals and their contents and analyzes whether projectors and architects follow the requirements and guidelines formulated in the BIM manual. The study also investigates whether the requirements and guidelines formulated in BIM manuals open up new thinking and innovation for the projectors and architects, or whether it may limit the projectors and architects innovation. The report is based on a qualitative method, where information is obtained from semi-structured interviews, and a literature study there data and information has been obtained from literature in the form of books, research reports, investigative reports, degree projects, documents and web pages. The study is limited to the design stage, where eight people have been interviewed and four companies have been studied. Staff interviewed are five BIM coordinators, a Section Manager within BIM, a department manager in charge of BIM and finally a plumbing projector.Based on the results of the study, it can be concluded that BIM manuals are not strictly followed in reality but more comprehensively. This is partly due to the fact that requirements and guidelines can be updated during the course of the project. Based on the study, it can be concluded that a BIM manual contains project-specific requirements and guidelines for the planned BIM models in order to create the organization and work processes that a BIM project seeks. Some examples of requirements and guidelines that can be formulated in a BIM manual are delivery formats for files, software and specific requirements and accounting technology. It can also be concluded that the requirements and guidelines defined in the BIM manual facilitate coordination during the course of the project, but that they are not rigorously followed. Another conclusion that can be determined from the study is that the BIM manual opens up for creativity and innovation for the projectors and architects as no technical solutions are defined in the manual. Finally, it can also be noted that what can be improved with the work on BIM manuals is that it can be more clearly explained to all the actors involved.After studying how BIM manuals are complied with in the design phase, a similar study can also be done to see how the BIM manual is followed in the management phase.

Full textSyftet med arbetet är att undersöka hur BIM kan implementeras i byggbranschen på ett bra och smidigt sätt ute i produktion. Detta ger NCC ett underlag för hur de ska gå tillväga för att denna process ska gå så lätt och smidigt som möjligt men också för att minska risken att fokus hamnar på fel ställe och att implementeringen utförs på ett sådant sätt att personalen blir mer negativa mot digitala hjälpmedel i produktionen. Då yrkesarbetarna är de som hittills jobbat minst med digitala hjälpmedel har störst vikt lagts vid att undersöka hur implementeringen kommer att påverka dem och hur man ska göra för att få med dem i denna förändring. BIM, Building Information Modeling, är egentligen byggbranschens digitalisering. Det bygger på att projekteringen utförs i 3D och sedan byggs modellen på med information som gör att arbetet kan effektiviseras och göras smidigare. Det går till exempel att rita upp hur väggarna är uppbyggda i skikt för att underlätta för kalkylatorn vid upphandlingar med underentreprenörer men också i produktion vid beställning av material. Detta minimerar dubbeljobb och effektiviserar produktionen. I projekteringen används det bland annat vid kollisionskontroller där olika discipliners modeller läggs ihop för att se om installationerna krockar någonstans. I förvaltning kan det användas genom att produkterna som använts läggs in i modellen, till exempel vilken armatur, för att sedan lätt kunna hitta den informationen när armaturen senare behöver bytas ut. Det pratas ofta om att BIM är dyrt och det stämmer att det blir en högre kostnad i början av projekten. Däremot sparas tid och pengar i produktion och förvaltning. Fel som tidigare har upptäckts i produktion och har behövt lösas på plats så gott som försvinner. Genom att intervjua personer som börjat använda sig av BIM i produktion har upptäckten gjorts att det finns bra och lätthanterliga program som underlättar och effektiviserar vissa delar av produktionen. Två av dessa program som används på NCC idag är Bluebeam och Dalux. Bluebeam används som dokumenthantering där länkar mellan olika ritningar gör att det går snabbt och enkelt att hoppa mellan ritningar. Dalux är ett lättanvändligt program där du kan se projektet i 2D och 3D samtidigt vilket ger en lättare förståelse för vad som ska byggas genom att du kan gå omkring i projektet i 3D. Dalux har även en gratis app som alla yrkesarbetare skulle kunna använda för att öka förståelsen av vad dom bygger vilket skulle kunna göra att frågorna till arbetsledningen skulle minska. Ett problem är då hur man ska lösa det med mobiler och surfplattor till alla, om man inte får använda sin egen eller äger någon privat. Ett annat problem med digitaliseringen är att hårdvarorna är väldigt ömtåliga och ska användas i en hård miljö samt så har internet en tendens att krascha med jämna mellanrum vilket gör att man alltid måste ha en backup av de aktuella ritningarna och modellerna. En annan fråga är hur man ska få alla att använda sig av de digitala verktygen. Här är de som intervjuats överens om att det med största sannolikhet handlar om hur intresserad man är av teknik och att det är en generationsfråga. De menar att det med generationsskiftet kommer bli lättare att implementera BIM i yrkesarbetarnas arbete. För att implementera BIM i produktion på ett så bra och smidigt sätt som möjligt bör ordentliga utbildningar av platsledning och yrkesarbetarna genomföras för att sprida kunskapen om vilka möjligheter som finns inom företaget men också för att ge personalen en bra grund så att de känner sig säkra i programmen när de ska börja användas. Det kan öka intresset även hos de som varit negativt inställda från början. Yrkesarbetarna bör använda programmen som visuell hjälp genom att gå omkring i 3D modellen och för att snabbare kunna navigera sig mellan olika ritningar genom länkar. Arbetsledarna kan ha en högre svårighetsgrad med fler funktioner, bland annat olika lager och möjligheten att uppdatera ritningar och modeller.

Full textThe use of CAD, within the building industry came strongly, during the 1980’s and the 1990’s. The development has since then rapidly progressed and the using of 3D-models has in addition increased. We are now at the edge of next step of evolution. BIM, Building Information Model(ing), is here. Briefly, BIM is an object oriented 3D-model, which contains information. The information is used in all phases of the building’s lifecycle. BIM simplifies the coordination and enables, among others, a more accurate calculation in an early phase of the process.
The purpose of the report is to present how BIM applies in practice. The report is based on interviews and observations at the projecting of Halmstad Arena.
BIM-technology isn’t completely ready yet, but it is on its way. Today BIM is most suited for complex projects. Once you have learned the work method, BIM will be superior the traditional 2D-projecting and applied to every project. New job types will be established, such as BIM-supervisor and building modeler, whom are specialized towards BIM. Even though the objective for all parts has been to work integrated and towards a common objective, with traditional projecting, we aren’t there yet. BIM doesn’t change the objective, but simplifies the approach.

Full textThe usage of Virtual Design and Construction (VDC) and Building Information Models (BIM) in the building industry is steadily increasing and has been the subject of several studies during the last couples of years. The majority of these have focused on the new production of buildings. However, with an increasing need for renovation in large parts of the Swedish housing stock there has been an increasing interest in using VDC and BIM in retrofit projects. In addition to that, new advances in the field of surveying, mainly through laser scanning, have provided new adequate tools to create building information models of existing buildings. The objective of this study has therefore been to investigate how a BIM of an existing building can be developed and how it can be used in a retrofit project. The results reported in this study are partly based on a survey consisting of various survey methods and partly on a compilation of experiences from individuals who worked as either a surveyor or in retrofit projects where digital 3D models where used in one way or another. The survey consisting of different survey methods was carried out mainly through a literature study, whereas the collection of experiences was carried out in the form of an interview study. The conclusions that could be drawn from these results show that there are a variety of benefits associated with the use of BIM in retrofit projects. The most pronounced benefits relate to the communication between different participants within the project and participants that are affected by the project in various ways. These participants may include the tenants or the users of the property who often lack the knowledge and the experience of reading traditional blueprints in 2D. The implementation of digital 3D models would facilitate communication with these participants. Further to this the study presents a proposal for a method that can be used when creating a BIM for a retrofit project. This method consists of eight steps, carefully explaining what a client interested in a 3D model should consider in order to avoid the pitfalls that this study has been able to identify.

Full textSyftet med den här studien är att underlätta hållbart byggande genom användandet av BIM. Målet är att utreda vilka aspekter inom hållbart byggande som kan analyseras med fokus på i huvudsak BIM-verktyg, men också andra hjälpmedel. Studien bygger på litteraturstudier och intervjuer. I litteraturstudien undersöks aspekter som är betydelsefulla vid hållbart byggande genom att studera miljöcertifieringssystem som är tillämpningsbara i Sverige, samt vilka BIM-verktyg som finns att tillgå på marknaden för att analysera dessa aspekter. Litteraturstudien innefattar även begrepp rörande BIM och hållbarhet för att ge en klarare bild av dess innebörd. Intervjuerna har tillfört studien övergripande förståelse för branschen och vägledning i ämnet. Resultatet redovisas i en tabell, där de aspekter som är relevanta för hållbart byggande är listade. I tabellen går det även att utläsa vilka aspekter certifieringssystemen tar upp. Totalt visar studien på 132 aspekter fördelade inom sju delområden; Platsen, Vatten och Avlopp, Energi och Föroreningar, Material och Avfall, Inomhusklimat och Välmående, Stadens Gestaltning samt Genomförande och Förvaltning. I tabellen redovisas dessutom förslag på BIM-verktyg samt andra hjälpmedel som används vid analys av en specifik aspekt. Studien visar att en knapp majoritet av aspekterna, 55 procent, är möjliga att analysera med BIM-verktyg. Platsen är det delområde som visar flest aspekter som går att analysera med BIM-verktyg, 95 procent. Material och avfall resulterade i minst aspekter med endast tio procent. Sammantaget har studien undersökt 35 stycken olika BIM-verktyg. De aspekter som kräver andra hjälpmedel för analys genererar ofta information viktig för projektet ur hållbarhetssynpunkt, och går i många fall att integrera i BIM-modellen manuellt. Sammantaget medför det att projektet får en fullmatad BIM-modell med användbar information som följer projektet ända in i förvaltning och sedermera rivning och återvinning. Studien visar att hållbart byggande handlar om att ha en helhetssyn där flertalet aspekter ska beaktas för att uppnå hållbarhet. Det räcker således inte att bara se till exempelvis energihushållning för att anse att ett projekt är hållbart. För att analysera aspekter rörande hållbarhet krävs att relevant och riktig information om projektet insamlas. Då kan olika förslag utarbetas och jämföras för att ta fram det mest hållbara alternativet. Ett redskap för detta är BIM. BIM är definierat dels som en arbetsmetod, byggnadsinformationsmodellering, men också som en virtuell modell, byggnadsinformationsmodell. BIM underlättar samordningen av den insamlande informationen, både som arbetsmetod och som tekniskt verktyg. På så vis bidrar BIM till att uppnå syftet hållbart byggande.

Full textThis dissertation presents the technology within BIM and its implication in the architectural and engineering design process. Since the 60 s, aerospace and automotive industries have already revolutionized the way of project with the CAD, and manufacture with the assembly lines. In AEC, the CAD became BIM, a new way of project, build and manage, from conception till life cycle building. This brought a project and construction time reduction, cost and environmental impacts decrease foreseen in LEED and merged in BIM.
Este trabalho objetiva apresentar a tecnologia contida no BIM e suas implicações no processo de projeto da arquitetura e engenharia civil. A partir de 1960, as indústrias, aeronáutica e automotiva, já haviam revolucionado a forma de projetar com o CAD, e de fabricar com as linhas de montagem. Na Arquitetura, Engenharia e Construção, o CAD está evoluindo para o BIM (Building Information Modeling), uma forma de projetar, construir e gerenciar, da concepção ao habite-se, aplicável a todo o ciclo de vida da edificação. Dessa forma houve não só uma redução no tempo de projeto e construção, mas também em custos e impactos ambientais previstos em normas internacionais incorporadas ao BIM.

Full textFire protection design in various projects is currently done in 2D-CAD where the files aresaved in PDF format. This was evident from the various interviews that took place inconnection with the report. This way of designing can cause various types of problems in theproject that occur for both the fire protection design and the others disciplines involved in thedesigning. When the fire protection design does not participate in using 3D-BIM in theprojects, collaboration of the models made by the architect or the BIM coordinator willcomplicate. The problems that may arise also consist of the possibilities not taken for BIMuse of the fire protection design. These opportunities and benefits can for example be a betterunderstanding of concepts and completed building, reduced time spent in the constructionphase, higher productivity and quality etc. [1]. There are also possibilities for the fireprotection design, where BIM facilitates the production of the fire protection plans and lifesecuritysystem drawings.Implementation of BIM in the fire protection design can be done in different ways. Followingthe literature studies, it has come to conclusion that BIM can be implemented in differentways for example by taking advantage of the various conditions that exist today. Theseconditions include different BIM software and BIM courses that makes it easier to implementBIM for the fire protection design. It is also possible to make proposals for the design of BIMin the specifications or in the CAD- and BIM manuals when procuring the various types ofcontractors. Requirements and rules can also be set by the government where a similarexample where made in the UK where the government demanded construction andinfrastructure projects to work with BIM at level 2 since April 2016 [2, 3].Boverkets byggregler can also make stricter requirements regarding the design by PBL andPBF, where they can demand that it should be done in BIM. Based on these problems,opportunities and conditions that exist today with the implementation of BIM in the fireprotection design, the transition will not be easy and will not be happening soon. But thisshould be done as BIM evolves all the time and then the transition from 2D CAD will be evenmore difficult in the future. Therefore, the fire protection design and the other disciplines inthe construction process should aim to work in 3D-BIM, as this is useful to all those who areinvolved in the project.

Full textThe potential for supplying large amounts of information throughout the construction process issomething BIM is mostly associated with. However, the practical use of BIM in facilitymanagement is minimal when compared to the project planning phase.Healthcare buildings are incredibly important and complex buildings in the society thatconstantly need to be maintained and this study addresses the potential of BIM and the use of asbuiltmodels to serve as a complement to today's and future facility management systems.This study has focused on finding out how the management of healthcare facilities uses andworks with BIM today and how they wish to work in the future. This has been done throughinterviews and document analyzes where a literature study forms the basis for the formulation ofthe questionnaires produced. The purpose has been to investigate what information a BIM asbuiltmodel (also called facility management model) must contain to be useable and useful in thefacility management.The theory of this study describes what BIM is and how the relationship with BIM and facilitymanagement looks. It also addresses the importance of sustainable information in open fileformats.The result of the collected data from the interviews shows that BIM is well known to facilitymanagement organizations but is not used to the extent desired. A few reasons for this are lackof; knowledge within the organization, influence in the construction process and workingmethods. All interviewees are positive to BIM and see the potential of using BIM models as theirdigital tools to visualize and manage information within the facility management. However have,in particular, the CAD/BIM representatives of the facility documentation difficulty in clearlyidentifying what information they want and thinks a lot of information in the models is better.The conclusion shows that organizations are dependent on evaluating their needs and findingbenefits with BIM in their facility management and then be able to set the right requirements forthe final delivery of the BIM model to be used in the facility management. The need to add,extract, update and modify information consistently, is something all interviewees sees as animportant question for the future.In the discussion chapter the problem arises about the fact that many interviewed thinks that themore information the BIM model contains, the better it is. The author's opinion is that the modelmust be adapted so that the right information is available.

Full textThis thesis aims to exemplify the information parameters necessary for Building Information Management in a better way will be able to implemented in the production phase. To achieve this goal, we have analyzed the development and use of Building Information Management through three different data collection methods; literature, observations and interviews. In this thesis we have extended us in the pros and cons and how Skanska Sweden AB may apply Building Information Management as a work tool in work briefings. This invasive treatment has led us to analyze the production custom information parameters as a production manager needs in its employment to take advantage of Building Information Management. We believe that the use of a BIM model complements the production manager's leadership skills, which makes it easier for him/her to convey information to skilled workers, then the visualization facilitates understanding of the task. More about the conclusions we have reached, the reader can take part of this thesis.

Full textThe Transportadministration wants to find out how to implement BIM (Building informationmodeling) as a way of working in their organization during design, constructionand management. The purpose of this study is to find out how BIM-models areused in communication today and how it can be developed. There are a few people today in the construction industry who have experience of working with BIM. Even in projects who work with BIM there is always a need for a BIM-coordinator who holds the strings. To get a good end result the communication within the project must be good. A condition for this is that all the involved parties have the same goals with the project, such as keeping the schedule better. Those who lack experience of working with BIM-models must be given a chance to understand it in order to be able to share their experience and knowledge with others. Knowledge must be enhanced and it will take time. It is important that there is not too much focus too much on technology because BIM is about more than just technology. First and foremost one must be clear about the ones goals of working with BIM. From this one can then define a process and ultimately decide which technology is best suited for this process.

Full textIn a BIM-project several intelligent 3D-models is being created. The 3D-models contain both geometries and information. Each discipline creates models containing their building and installation components. By coordinating the models from all the disciplines, a BIM-model of the entire project is being created. A prerequisite for the design to be effective is that the models have a good quality. Today there are good opportunities to facilitate the work of quality assurance, since more and more buildings are designed in 3D. There are several softwares for merging and checking models. In addition to detecting collisions and quality defects, the software can do several tasks to make projects more effective. One feature is the ability to virtually walk around in the building before it is constructed. It is also possible to measure distances, draw and make notes in the model and its views, which is helpful when it will be reviewed by the various disciplines. The background to this thesis is that the consultancy Byggteknik AB would like to know what software for coordination that meets their needs best. By implementing the software, they want to be able to assume responsibility for coordination in future BIM-projects. The question for this thesis is: What software is best suited for the consultancy Byggteknik AB? To answer the question a case study was conducted. In the case study three different softwares for quality and collision checks was being compared. The softwares being compared were Autodesk Navisworks Manage, Solibri Model Checker and Tekla BIMsight. The answer to the question, presented in this report, is that Autodesk Navisworks Manage in the current situation is best suited for Byggteknik AB.

Full textBuilding Information Modeling, BIM is a complex idea which has varying meaning depending on where in the building process it is used. There is no simple definition of how the working with BIM is applied and consists of many areas of activity. This report is based upon the study of available literature and interview questions, which both have set the ground for the result and conclusions presented. These have aimed to investigate how digital information processing can be applied in the facility management for a building and furthermore, how inventory of an already built building can be improved by today’s technology. By studying what´s already have been written on the subject and contacting people who works in the building consulting business or building facility management, a combination of available techniques is presented. The bottom-line is that BIM (Building Information Modeling) is a modern working method which can be used by all disciplines for applying information to a project, and which also can be used progressively into production, facility management, rebuilding and renovation, and finally deconstruction. Inventorying of an old building which lacks data can be recreated by the use of laser scanner technique and gives a reliable collection of data, which afterwards is processed in a CAD program. Studies have been made in order to find a way for localizing inbuilt material without making any permanent damage to the building construction.

Full textPurpose: The purpose with our thesis is to analyze to what extent BIM is used in the calculation work, and how to overcome the obstacles of implementing BIM in the calculation work. Method: We have used literature analysis and a number of qualitative interviews. Findings: The outcome of our thesis is that there are several obstacles to overcome in order to increase the implementation of BIM in the calculation work. One of the obstacles is that BIM structures are missing in the specifications from the clients and if they are included they do not live up to the standard necessary. Further obstacles are the juridical and technical problems alongside with the industry’s resistance towards new techniques. Insufficient education in BIM tools, and the lack of a common industrial standard are problems as well as there’s a need to help the involved operators acquire knowledge that BIM is a tool that everyone can benefit from. Implications: BIM has the potential to give more precise, more timesaving and more accurate calculations in the calculation work. When analyzing our work, we feel that Peab is on the right path. They don’t wait for the clients to give them a useful BIM structure together with the tender documentation. Instead, the management have decided to make geometrically correct structures themselves that are useful to the calculation engineer. They have realized the importance of providing the calculation engineer with the proper digital tools and education of these tools so that they can benefit from the advantages BIM can give in the calculation work. In order to drive the implementation of BIM forward, there might be a need for some workarounds in the form of national rules about standardizations are to be formed. These standardizations can make it possible to ease the process of implementing BIM and that these standardizations can overcome obstacles in the information exchange between the clients. To increase the use of BIM it’s recommended that a BIM coordinator is selected, who can make demands on the various clients about how files and documents should be designed in order to be able to use them, not just in the calculation stage but also further into the project. In order to drive the implementation of BIM forward, a solution to the juridical obstacle are needed. As it is now, rules to include digital information in the acts are missing in the standard documents. Changes need to be done in order to attach the contractor and the client`s responsibility and usufruct of content in the delivery of digital information. Limitations: We have limited ourselves to only analyze how BIM are used today and how it may be used in the calculation work in the future.
