The building industry are currently going through a huge alteration. The introduction of BIM (Building Information Modeling). Which also implements a lot of new ways of solving problems that building modeling can cause. This report is written for Uppsala University in cooperation with Temagruppen in Uppsala. However, it contains a comparison between two different systems that checks building models. Temagruppen invested in a new Swedish adaptation of a software called Solibri Model Checker. This Software controlling the availability in building models, it also introduces a new way of interaction between different instances during a building project. The definition of the report is availability in public buildings. A building model has been designed in Revit, then imported to Solibri Model Checker who controls the availability and creates a report of certain design fault. Interviews are given to get a look into how the work with availability controls currently works at Temagurppuen. This results in a discussion of benefits and disadvantages of the two different methods. The result finally shows that certain work can be more effectively done with Solibri Model Checker. But availability contains more than just disabled impairment. Visual- and cognitive impairment can’t still be controlled by just a computer software.

Utvecklingen och etablerandet av BIM vid projektering av ventilationssystem har förenklat arbetsprocessen för branschens projektörer. BIM har med 3D-objekt förändrat projekteringen i byggbranschen och har successivt etablerat sig och används av projektörer runt om i hela världen. 3D-modeller ger möjlighet att tidigt utföra beräkningar på blivande system och se om kraven som ställs blir uppfyllda.  Det vanligaste använda BIM-verktyget för projektering av VVS-system är MagiCAD, som är en tilläggsapplikation för både Revit och AutoCAD. MagiCAD i Revit-miljö är relativt nytt i byggbranschen som börjar etablera sig och används idag av VVS-projektörer i över 75 länder runt om i världen. Rapporten avser att testa tillförlitligheten för beräkningar i luftbehandlingssystem utförda i Revit MagiCAD. Resultat från traditionella tillvägagångssätt vid liknande beräkningar jämförs mot de resultat som genereras i Revit MagiCAD. Tillförlitligheten ansågs vara hög då resultat från både handberäkningsmetoder och MagiCAD var likvärdiga. Revit MagiCAD kan därför anses vara ett tillförlitligt beräkningsverktyg för distributionssystem i VVS-installationer. / The progress and establishment of BIM for designing ventilation systems have simplified the work process for the industry's projectors. With 3D objects, BIM has revolutionized the design in the construction industry and has gradually established itself and is used by HVAC and MEP designers around the world. 3D models provide the opportunity to perform calculations on projected systems early and see if the requirements are met. The main BIM tool for designing air distribution systems is MagiCAD, which is an application in both Revit and AutoCAD. Revit MagiCAD is relatively new in the construction industry but is also starting to establish itself and is today used by HVAC and MEP engineers in over 75 countries around the world. The report aims to test the reliability of calculations in air distribution systems performed in Revit MagiCAD. Results from traditional approaches in similar calculations are compared against the results generated in Revit MagiCAD. Reliability was considered high when results from both hand calculation methods and MagiCAD were equivalent. Revit MagiCAD can therefore be confirmed as a reliable calculation tool for distribution systems in plumbing installations.

Trots att Building Information Modelling (BIM) existerat i byggbranschen en tid är entreprenadföretagen inte långt fram i utvecklingen. BIM är en arbetsmetod som samlar all information om ett byggprojekt digitalt och att alla ingående aktörer samarbetar. Utvecklingen av BIM har hindrats på grund av en investeringskostnad och kunskapsbrist på entreprenadsidan. Detta leder till att det tar lång tid för företagen att införa BIM. Genom att skapa ett likartat arbetssätt frambringas tydligare riktlinjer. Detta ökar tryggheten och fler känner sig bekväma med att använda BIM och att lära sig den nya tekniken. Detta arbete undersöker om ett standardiserat arbetssätt kan vara till hjälp hos ett entreprenadföretag inom vidare införande av BIM med hjälp av programvaran Revit. Arbetet började med hjälp av litteraturstudier och kritisk granskning av referenser. Intervjuer från entreprenadföretaget har genomförts på ett semi-strukturerat vis för en bredare förståelse gällande den påbörjade implementeringen av BIM samt vilka arbetsmetoder som används idag. Det genomfördes studier av befintliga arbetsmetoder för djupare förståelse gällande vad som krävs vid framtagandet av ett standardiserat arbetssätt. Intervjuerna visar på att det är välkommet med ett standardiserat arbetssätt hos företaget. Det efterfrågas stöd för användningen av programvaran Revit och effektivisering av deras arbetsmetod vid mängdavtagning. Arbetssättet kommer agera i form av en manual som anpassas utefter företagets egna Revit-mall. I framtiden kan manualen användas i utbildningssyfte. Visionen är att allt flera på företaget skall kunna etablera arbetsmetoden successivt i deras framtida projekt. Detta bidrar där med till företagets framgång och utveckling på marknaden. / Though Building Information Modelling (BIM) has existed in the building business for a time the construction companies are not as far in the process. BIM is a working method that handles all the information included in the building project digitally and how everyone involved collaborate. The BIM progress has been constrained because of the investment costs and lack of knowledge in the construction companies. This concludes that it takes time to establish BIM into the companies. By creating a similar working method a clearer guideline will be generated. This will increase self-assurance and more will feel comfortable using BIM and learn the new technology. This essay investigates if an equivalent working method will be of use at a contractor company that are establishing BIM with the software Revit. This essay started with literature studies and critical reviews of references. Interviews at the construction company have been made in a semi-structured way for a wider understanding about the started implementation of BIM and what working methods they are currently using. Studies of existing working methods have been made for a deeper understanding considering developing an equivalent working method. The interviews show that an equivalent working method for the company is welcome. There are requests for software support in Revit and make the existing working method more efficient while making material quantities. The equivalent working method will act in form of a manual that is custom for the company’s own Revit template. I the future the manual can be used in educational purposes. Therefore contribute for the company’s prosperity and growth in the business market.

The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH &amp; Co. KG and this report has been made for their Swedish division Layher AB.  The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn’t able to withstand the loads. The main problem is the greater snowloads which has been proofed to be the most unfavorable load for the Kedertruss. Apart from the commission from Layher AB a parametric controlled model of the Kedertruss has been made in Revit Structure

This Degree project summarizes how it is to work in the CAD program Revit Architecture. This was done because AQ Arkitekter in Eskilstuna is interested in how Revit works. Especially compared to AutoCad which is the software they are using today. Will their work become more efficient with the new software? The starting point was to find out how it is to work with Revit when you only used AutoCAD Architecture before. The purpose with this Degree project was to investigate whether it was possible to provide all the drawings required in a construction project that AQ Arkitekter normally produce in AutoCAD. Most of the study was done on my own with some help of outside contacts. Drawings from an already completed construction projects were produced in Revit to really see if it was possible to obtain the required drawings. The final results were a summary of the Revit features and how to generate drawings. The two programs were compared to see the disadvantages and advantages of the programs. In the end, the Degree project did become a complete report, which gives an overview of Revit and its functions.

The society strives for sustainable development, in the construction industry it is expressed through sustainable building. Energy and LCC analyzes increases the ability to make conscious decisions in the process. A problem in the construction industry is that energy and LCC analysis is not used to the desired extent, as they are perceived as complicated and time consuming. The report aims to achieve a more sustainable building through increased use of energy and LCC analyzes.The goal is to show how BIM can be used to improve the efficiency of the energy and LCC analyzes. The study was conducted with a literature review and a case study to answer which information that is required in a BIM model to perform energy and LCC analyzes. The study also shows which software can be used in BIM based energy and LCC analyzes and how the analyzes can be carried out efficiently. The result shows that effective analyzes may be performed if the BIM-model contains the relevant information for making analyzes. Information not necessary for the analysis complicates the procedure. There are a variety of software that manages energy and LCC analyzes differently. The Software’s are optimized for different BIM platforms and they use various file formats for the transfer of information. Effective analyzes are achieved by following a proven method or guide with few steps in the workflow. Through knowledge of the capability of the used file format, the right information can be added to the model at the right point in the process of analyzes without loss of information. To increase the use of energy and LCC analyzes, an integration of the analysis tools into the BIM platforms would be necessary. / Samhället strävar efter ett allt mer hållbart byggande som reducerar påfrestningarna på miljön. Energi- och LCC-analyser(LifeCycleCosting, eller Livscykelkostnad) ökar möjligheten att fatta medvetna beslut i processen. Ett problem inom byggbranschen är att energi- och LCC-analyser inte används i önskad utsträckning då de upplevs som komplicerade och tidskrävande. Syftet med rapporten är att få ett mer hållbart byggande genom en ökad användning avenergi- och LCC-analyser. Målet är att visa hur BIM kan användas för att effektivisera energi- och LCC-analyser. Studien har gjorts med en litteraturstudie och en fallstudie för att besvara vilkeninformation som krävs i en BIM-modell för att utföra energi- och LCC-analyser. Studien visar även vilka mjukvaror som kan användas vid BIM-baserade energi och LCC-analyser och hur analyserna kan utföras på ett effektivt sätt. Resultatet visar att effektiva analyser kan genomföras om BIM-modelleninnehåller relevant information för att göra analyser. Annan informationkomplicerar analysförfarandet. Det finns en stor mängd olika mjukvaror somhanterar energi- och LCC-analyser på olika sätt. Mjukvarorna som kan göra energianalyser är optimerade för olika BIM-plattformar och använder olika filformat för informationsöverföring. Genom kunskap om filformatens kapacitet, kan rätt information tillföras modellen vid rätt moment i analysprocessen utan att information går förlorad. För att göra effektiva analyser, är användandet av en beprövad metod eller guide önskvärt. En möjlighet för att öka användandet av energi- och LCC-analyser, skulle vara att en integration av analysverktygen in i BIM-plattformarna utvecklades.

The regulations for energy consumption are consistently getting more and morestrict. This leads to a higher customer demand for energy analysis early in the buildingdesign process. Many building planners and architects use powerful modeling softwareto visualize their projects. These digital models contain sufficient information aboutthe building’s physical characteristics for reliable energy analysis. This report evaluatesthree different energy analysis software tools and their compatibility with themodeling software Autodesk Revit Architecture. The results in the report are basedon simulations made with a fictional model in the different tools. Some of the resultsobtained from the different programs are not consistent and because of the difficultiesin evaluating these differences the usefulness is limited. Based on several criteria thesoftware have been evaluated and a recommendation for the company Tema has beenproduced. Due to the complexity of energy analysis, the software requires certainpre-knowledge of the subject by the user to perform an accurate analysis. Inconclusion, the software which is best suited for preliminary energy analysis is,according to the author, VIP-Energy because of its efficiency and credibility.
