Academic literature on the topic 'BIM-projektering'

<p>The 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. </p><p>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. </p><p>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.</p>

The construction industry depends on functioning logistics; if the logistics isn’tworking the construction site will risk to be interrupted due to material shortages orproblems with deliveries. Despite this, the construction industry is battling logisticproblems daily. This problem is very time consuming and costly for the companies.These theses are written for Peab Bostadsproduktion and investigate if it is possibleto focus on logistics earlier in the building planning process to reduce the problemsthat occur. Peab has partnerships with three companies that could be helpful for themin the work of reducing logistic problems. These three companies are Vico, BEAst andBIMobject.The thesis first section gives a general review of logistics, as well as the conceptsrelated to it. A general review of the above named partners is also given. In the firstsection the meaning of BIM is also explained. The core of the thesis consists of asurvey with craftsman from one of Peabs construction sites. The other main part isinterviews with officials from both the production side and from Peabs headquarters.The survey and the interviews have then been collected and analyzed. Based on theresult that was gathered, suggestions and solutions are presented and discussed.The work shows that many of the logistical problems that occur can be reduced orcompletely prevented by implementing these three in all Peabs own managementbuilds.

Denna rapport syftar till att bistå projekterings- och produktionspersonal med effektiviserande verktyg och metoder för att med BIM som bas öka och förenkla informationsutbytet. NCC använder idag BIM-metoder för projektering av projekt, däremot nyttjas inte BIM-metodernas fulla potential för samarbetet mellan disciplinerna i projekten.   För att undersöka behovet inom produktionen hölls intervjuer med personal från ett brett spektrum av åldrar och befattningar. Intervjuerna låg sedan till grund för kriterier till utvärdering av BIM-verktyg. Intervjuerna hölls även med personal med befattningar som projekteringsledare, modellsamordnare och konstruktör, för att med deras kunskaper utvärdera BIM-verktyg.   För att på ett verklighetsförankrat vis utvärdera digitala verktyg i form av BIM-verktyg modellerades ett hus i Tekla Structures 21.1 och Revit 2015. Även A- och K-modellerna för NCCs projekt Trollhättan 33, T33 fanns att tillgå för tester.   Från utvärderingarna utkristalliserades två program som författarna anser vara bäst i respektive stadium av byggprocessen i det studerade projektet, T33. Solibri Model Checker, SMC anses som bäst lämpat verktyg i projekteringsskedet och Trimble Connect anses bäst under produktionsskedet. Solibri Model Checker har bäst möjligheter för validering och kvalitetskontroller och Trimble Connect är ett verktyg där modeller och handlingar kan lagras för enkel kommunikation och samarbete i projektgrupper. Verktyget har även möjlighet att visuellt presentera modeller och handlingar på en dator, surfplatta eller mobiltelefon. De BIM-verktyg som utvärderades var: Solibri Model Checker v9.6 Autodesk Navisworks Manage 2016 Autodesk BIM 360 Glue Trimble Tekla BIMsight Trimble Connect<br>The 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

Byggbranschens effektivitet beror på många faktorer, en av dem är logistik. Välplanerad logistik kan bland annat minska slöseri av tid och kostnader. Studier har tidigare visat att ineffektiv tidshantering i byggbranschen förekommer oftare än i branscher. Examensarbetet har skrivits för att undersöka vilka problem kan förekomma i logistikprocessen och hur digitalisering kan förebygga problem i logistikflödet. Digitalisering som återspeglas i Building Information Modeling (BIM) skapar möjligheter för att uppnå ett effektivt logistikflöde. Rapporten innehåller två huvuddelar: Faktainsamlingen omfattar begreppet logistik och olika strategier relaterade till ämnet som Lean och Just In Time och tillämpningen av dem i byggbranschen. Jämförelser mellan olika standarder kopplade till förbättrad hantering och klassifikation av material tas upp, bland dessa BEAst och Coclass. Även BIM-projekteringens inverkan på logistik har teoretiskt undersökts med programvaran Vico Office och dess 4D samt 5D-funktioner. Den andra delen fokuserar på enkätundersökningar på byggarbetsplats och intervjuer med BIM-specialist, logistikchef, forskare med utvalda intervjufrågor. Frågorna är utformade efter respektive arbetsroll och alla svar finns transkriberade i slutet av rapporten som bilagor. All samlad information från enkätresultat och intervjuer redovisas i resultat och analys för att slutligen diskutera fördelar och nackdelar med BIM-projektering för logistiska ändamål. Rapporten föreslår mer användning av BIM-projektering i projekteringsstadiet för att effektivisera logistik i byggbranschen.<br>The efficiency of the construction industry depends on many factors, one of which is logistics. Well-planned logistics can, among other things, reduce waste of time and costs. Studies have previously shown that inefficient time management in the construction industry occurs more often than in other industries. This report has been written to investigate which problems can occur in the logistics process and how digitization can prevent problems in the logistics flow. Digitization reflected in Building Information Modeling (BIM) creates opportunities for achieving an efficient logistics flow. The report contains two main parts: The collection of facts covers the concept of logistics and various strategies related to the topic such as Lean and Just In Time and their application in the construction industry. Comparisons between different standards related to improved handling and classification of materials are addressed, among them BEAst and Coclass. The impact of the BIM design on logistics has also been theoretically investigated with the software Vico Office and its 4D and 5D functions. The second part focuses on surveys about construction workplaces and interviews with BIM specialists, logistics managers, researchers using selected interview questions. The questions are designed according to each work role and all answers are transcribed at the end of the report as appendices. All collected information from the survey results and interviews are presented in results and analysis to finally discuss the advantages and disadvantages of BIM design for logistics purposes. The report proposes more use of BIM design in the design stage to streamline logistics in the construction industry.

Building Information Modeling (BIM) är en relativt ny arbetsmetod i byggbranschen som allt fler företag anammar i sina olika projekt. Med hjälp av BIM kan projektets arbete effektiviseras redan i ett tidigt stadie. Då man till exempel kan utföra kollisions kontroller i skapade 3D modeller de olika aktörerna i mellan redan i projekteringsfasen och på så vis undvika problem när byggarbetet väl har startat. BIM processen består av tre delar. De kallas 3D, 4D och 5D vilket omfattar 3Dmodulering, tidplanering och kostnadskalkylering. I denna rapport riktas fokus på tidplaneringsfasen för att ge en bild av hur arbetet skulle kunna bli bättre om BIM användes för att tidplanera och dess hinder i utvecklingen i användningen av BIM. För att få en uppfattning av hur det var att planera utfördes en jämförelse av Gantt planering och Flowline planering. Där en Flowline planering upprättades från en befintlig Gantt planering för att se hur de olika metoderna skiljer sig åt.<br>Building Information Modeling (BIM) is a relatively new method of working in the construction industry that more and more companies embrace in various projects. With the help of BIM project work efficiency can be increased at an early stage. For example, I can perform collision checks in the created 3D models of the various players already in the planning phase, this can help avoiding problems when the construction work has started. BIM process consists of three parts. They are called 3D, 4D and 5D and include 3D visualization, scheduling and costing. In this report the focus is mostly on time planning phase to provide a picture of how the work could be better if the BIM was used to planning and its obstacles in the development of the use of BIM. To get an idea of how the planning was carried out as a comparison of the Gantt planning and Flowline planning was made. Where a Flowline plan was established from an existing Gantt planning , then to see how the methods are different from each other.

This report brings up the question - ”Is BIM profitable when planning a single-family home?”. The methodology for finding the answer to this question is firstly to state the definitions of BIM and the company that is projecting by using the BIM-model. The answer is then obtained by analyses of the factors of profitability with respect to: time, opportunity of revision, problem visualization, preference adjustments and energy. A BIM-model has been made simultaneously as the writing has proceeded to get a perception of how a BIM-model really matters for the analysis. The analysis shows that the answer for the question depends on further factors. The factors that are mostly discussed are the company’s intentions and the complexity of the house. However, the answer to the question is no for most types of single-family homes.

Begreppet BIM (Byggnadsinformationsmodellering) har kommit långt inom husbyggnadssektorn och installationsbranschen medan anläggningsbranschen har legat efter i utvecklingen. Idag är anläggningsbranschen i stort behov av effektivisering och erfarenhet inom området BIM. Bristfällig kompetens och dålig information utgör några risker som behöver lösas för att få fart på utvecklingen. Detta examensarbete är utfört åt Trafikverket i Stockholm och genomfördes som en intervjustudie med totalt 12 olika ansvariga från både interna och externa företag. Varje person som intervjuades hade en koppling till de anläggningsprojekt vi fått som uppgift att kartlägga. Syftet med examensarbetet är att kartlägga vilka BIM-relaterade arbetsmetoder som redan används inom Trafikverket och hur de tillämpas med avseende på risker och projektering. De risker som kommer att undersökas är vid projektets utförande- och projekteringsskede samt en liten överblick på förvaltning och standardisering. Resultatet ska användas som underlag i framtagandet av ett gemensamt arbetssätt för BIM på Trafikverket. Resultatet visar att det saknas en tydlig definition av BIM. Studien visar att de främsta användningsområdena där BIM kan användas i anläggningsprojekt är anläggningsinformationsmodell, maskinstyrning, kalkylering, tidsplanering, visualisering och samgranskning. Slutligen ska byggnadsinformationsmodellen kunna användas som relationshandling för förvaltning. Ett flertal risker har tagits upp inom användningsområdena som tex hinder vid implementering av BIM. Användningen av BIM kommer att växa i framtiden och med ny teknik fås nya möjligheter och affärsmöjligheter som kan generera en stor mängd nya affärer i branschen. BIM kommer att skapa en gemensam plattform som kontinuerligt uppdateras och på så sätt skapar många nyttor för Trafikverket. Projekteringen blir effektivare och håller högre kvalité samt bidra till en bättre produktionsprocess.<br>The concept of BIM (Building information modelling) has come a long way in house construction and building services industry while the infrastructure sector has remained behind in development. The infrastructure industry is in great need of efficiency and experience in the field of BIM. Lack of skills and poor information pose some risks that need to be solved in order to boost the development. This thesis is done in the Swedish Transport Administration in Stockholm and was conducted by an interview with a total of 11 liable people from both internal and external companies. Each person who were interviewed had a connection to the infrastructure projects that we have been tasked to identify. The purpose of the thesis is to identify what BIM-related working methods already in use within the Swedish Transport Administration and how they are applied with respect to risks and planning. The risks that are investigated are in the project design, planning and construction stage. We also provide a small overview on management and standardization. The results will be used as a basis in the development of a common approach for BIM in the Swedish Transport Administration. The results show that there is no clear definition of BIM. The study shows that the main areas of BIM can be used in the infrastructure project machine control, accounting, scheduling, visualization and review. Finally, the building information model can be used as a relational document for management. Several risks have been addressed within the fields of application and obstacles in the implementation of BIM. The use of BIM will grow in the future and with new technology available, new opportunities and business opportunities occur that generates a large amount of new business in the industry. BIM will create a common platform that is continually updated and thereby create many benefits for the Swedish Transport Administration. The designs are more efficient and have higher quality and contribute to an improved production process.

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.
