Dissertations / Theses on the topic 'Autodesk Revit'

Building information modeling (BIM) is widely used in the construction industry today, and is fast becoming the standard for developers planning building projects. Industry leaders in the engineering and architecture business usually have well thought out and efficient ways of working within this field, but with ever increasing competition these companies are forced to continually find ways of streamlining their practices to stay ahead of the competition. There are often several different companies involved across multiple disciplines when it comes to the modeling of a building, and the different BIM tools available offer many ways for them to coordinate.   The purpose of this study is to examine whether one of the collaboration tools available in Autodesk Revit called Copy/Monitor could help to streamline the modeling process. The tests done of the collaboration tool were applied to a three-dimensional model of a building. Through practical use of the different functions, and compiled theoretical knowledge, the study shows that there are advantages of using this tool when planning multi-disciplined projects in Revit. The possibility of monitoring changes of elements when linking models is a powerful function and could prevent time consuming reworking later on in the project. It is of great importance however to note how the models are constructed, what type of project it is, as well as personal preferences when it comes to how the workflow should operate and what elements should be monitored.   Another purpose of the study was to give an explanation of coordinates in the software. Through theoretical compilation and practical tests the study shows that handling of coordinates when linking models works as the theory suggests. It is worth noting however that problems may arise in later stages of the project if the users that originally created the models are unaware of what the software’s different settings mean. There must be strict guidelines for how the coordinates should be handled from the start of the project, to avoid errors down the line that may be hard to identify and correct.
BIM-projektering är i dagsläget inget främmande inom byggbranschen utan används i de flesta byggnadsprojekt och är ofta ett krav från beställare. De främsta aktörerna inom teknik och arkitektur har vanligen inarbetade och väl beprövade arbetssätt inom detta område. Men eftersom konkurrensen i branschen ökar, och dessa företag har för intention att fortsatt ligga i framkant söker de alltid efter sätt att effektivisera deras arbete. Vid projektering av byggnader är det vanligt att flera olika aktörer är inblandade i multidisciplinära projekt. Det finns många BIM-verktyg på marknaden idag, och funktionerna för samverkan och koordination inom dessa är många. Denna studie ämnar utreda huruvida ett av de samarbetsverktygen som finns i Autodesk Revit kallat Copy/Monitor skulle kunna effektivisera arbetet med projekteringen. De tester som har gjorts av samarbetsverktygets funktioner tillämpades på en tredimensionell modell av en byggnad. Genom praktiska försök av funktionerna och sammanställd teoretisk kunskap visar studien att det finns fördelar med att använda detta verktyg i multidisciplinära projekt i Revit. Möjligheten att övervaka ändringar av element vid länkning av modeller är en kraftfull funktion som kan förhindra tidskrävande omarbetningar längre fram i projekt. Det har emellertid stor betydelse hur modellerna är uppbyggda, vilken typ av projekt det är, samt personliga preferenser när det kommer till hur arbetsgången ska se ut och vilka element som bör övervakas. Studiens syfte var även att ge en beskrivning av koordinater i programvaran. Genom litteraturstudier och egna praktiska försök visar studien att koordinathantering vid länkning av modeller fungerar som teorin beskriver. Det kan däremot uppstå problem längre fram i projekt om de användare som ursprungligen skapar modeller inte vet vad programvarans olika inställningar innebär. Det måste finnas tydliga riktlinjer för hur koordinater ska hanteras redan i början av projekt för att fungera felfritt i ett senare skede, annars kan dessa problem vara svåra att spåra.

Att kunna exportera färdiga modeller direkt från Revit till IDA är av stor betydelse för att kunna jobba effektivt med energisimuleringar. Denna rapport ger en bakgrundsbeskrivning till hur IFC har uppkommit och är uppbyggt. Dock ligger huvudfokus på hur Revit kan implementeras i arbetsflödet, där både hur IFC-filer överförs mellan programmen och felsökning av problem med befintliga Revitmodeller beskrivs. IFC-filer är dagens standard för att överföra data mellan olika instanser under byggprocessen, det är ett programoberoende format som möjliggör samarbete mellan olika programvaror. Dagens standard är IFC4, men det vanligaste formatet idag är IFC2x3 då det nya formatet ännu inte har implementerats i alla programvaror. Vilken geometri och information som ska exporteras från Revit till IDA är ett omfattande arbete att ta reda på och ställa in. Därför innehåller denna rapport både en lathund för exportering, men även flera filer för automatisk inladdning av korrekta exporteringsinställningar i Revit. För att kunna genomföra en energisimulering krävs det att rummen är förslutna för att undvika extrema köldbryggor som kan uppstå om väggarna inte är ordentligt anslutna med taket och golvet. Därför finns flera åtgärder beskrivna för att undvika fel i simuleringen, bland annat kring problem med fönster, dörrar och problem med lagerhantering. Beskrivningen utgår ifrån att användaren inte har tidigare erfarenhet av Revit. Guiderna har testats på en gymnasieklass i ämnet CAD där resultatet visade att en stor del av lathunden kan användas av en nybörjare. Dessutom studeras skillnader i Revits verktyg för simulering mot IDA. Där samma modell simulerades på åtta olika platser och standardavvikelsen mellan resultatet beräknades, detta gav ett koefficientintervall på ± 4 %, dvs. att en simulering i IDA inte bör avvika med mer än ± 4 % i jämförelse med den som gjordes i Revit. Liknande resultat uppmättes när simuleringsskillnader i dörrar och fönster simulerades. Där en stor glasyta på en vägg kommer generera ett koefficientintervall på 3 %. Om fönstren ersätts av dörrar kommer avvikelsen att minska något till strax under 2 % sett till alla väderstreck.
It is extremely important to be able to export models directly from Revit to IDA for the energy simulations to be efficient. This report has a background description about how the IFC-format has been developed and how it is structured. However, the focus in the report is on how Revit can be implanted in the workflow, where both export and troubleshooting from Revit are described. IFC is the standard today to export data between various parts during the construction process and it is a format that is program independent, which means that it works across different applications. The current version of IFC is IFC4, but IFC2x3 is still the most used version since not every program has support for the new IFC4 format. It is extensive to figure out which data IDA requires for energy simulations, therefore this report contains both a tutorial for export settings and a file for automatic set correct export settings in Revit. To succeed with the energy simulations a requirement is that the space in the building is enclosed with walls, floor and roof, otherwise extreme thermal bridges will cause incorrect simulations. Therefore, there are several workarounds described in this report to correct these problems, including problems with windows, doors and problems with storage facilities . The description in this report is written with the assumption that the user do not have any experience with Revit. The guides were tested on a class of high school students that are studying the course CADCAD02. The result showed that when a problem occurs with a model it can easily be solved with the support from this report. Further differences between simulations in Revit and IDA were tested. The same model was simulated in eight different places and the standard deviation was calculated, this gave the coefficient range ±4 %, i.e. a simulation in IDA should not differ more than 4 % from the simulation in Revit. Similar results were found with the simulations of windows and doors, even though the difference was slightly lower.

Byggnadsinformationsmodellering (BIM) är det informationshanteringssystem som de flesta konsultföretag och beställare strävar att implementera. Många har redan tillämpat BIM-metodiken som en del av byggprocessen. Eftersom tekniken går framåt tvingar detta också individen att utvecklas. Svårigheter uppstår när tekniken går framåt utan att den implementeras på rätt sätt av branschen. Problem finns i överföringen av information mellan olika parter. Ett av dessa problem är vid mängdavtagningar och kalkyler. Ett företag som ligger i framkant i utvecklingen och gärna vill effektivisera processen är Sweco Architects i Uppsala. De vill med hjälp av detta examensarbete undersöka beställarens krav och önskemål gällande kalkylering och mängdavtagning. Examensarbetets syfte är att med hjälp av en intervjustudie visa vad beställaren tycker behöver förändras och förbättras inom kalkylering och mängavtagningar från projektören. Målet med arbetet blir att med hjälp av intervjustudien ta fram en metodik till projektören som följer beställarens kravställning. Metodiken riktas in mot programvaran Autodesk Revit. Slutsatsen av arbetet är att en tydligare dialog mellan beställare och projektör behövs för att kunna förbättra mängdavtagningarna, men även en bättre arbetsmetodik för litterering. För att säkerställa detta bör en branschstandard upprättas men tills dess måste kravställningen bli tydligare.

L’elaborato di tesi verte nello studio dell’applicazione della modellazione BIM in costruzioni esistenti. Sono stati presi in considerazione diversi casi di studio: dallo lo studentato di Atene, sviluppato nell’ambito del progetto H2020 Pro-GET-onE, agli edifici posti al “Villaggio Costanzo Ciano” ed al quartiere “Pilastro” di Bologna. Attraverso i software BIM di Autodesk, Revit e Robot Structural Analysis è stato creato dapprima un modello “prototipo” aventi caratteristiche comuni con gli edifici popolari nati nel secondo dopoguerra e successivamente adattato ai casi di studio. Si andrà quindi a valutare come, grazie al vantaggio dell’utilizzo del processo BIM, si sia in grado di effettuare valutazioni di prestazioni e miglioramenti sismici in breve tempo. Il fine lo possiamo quindi ricondurre nel riconoscere le criticità dell’applicazione della modellazione BIM su costruzioni esistenti.

Den tekniska utvecklingen går fort fram. Tillämpandet av BIM (Byggnadsinformationsmodellering) blir allt vanligare inom byggsektorn. Dock halkar förvaltningen efter i utvecklingen, i jämförelse med byggprocessens tidiga skeden, projektering- och produktionsskedet. BIM i förvaltningen är väldigt omtalad men ännu har det inte implementerats i stor utsträckning. Detta arbete handlar om att undersöka huruvida digitaliserat förvaltningen är idag samt om mjukvaran BIM 360 Ops kan vara ett effektivare alternativ. BIM 360 Ops är en mjukvara skapad av Autodesk som riktar sig in på förvaltning. Genom intervjuer med Diagona AB, Fabege, HSB, Uppsala Kommuns fastighetsaktiebolag (UKFAB), Akademiska Hus, Locum, Stockholmshem samt FastPartner, får man en inblick i hur dessa företag går tillväga i dagsläget, vilka kunskaper det finns kring BIM hos förvaltare samt vad som saknas i förvaltningen. Här analyseras programvaror som respondenterna använder sig av, för att få en större uppfattning kring arbetsgången i förvaltningen. Ett detaljerat tillvägagångssätt av mjukvaran BIM 360 Ops demonstreras för att visa hur programvaran fungerar och för att upptäcka eventuella svårigheter, fördelar samt nackdelar med programmet. Resultatet visar att ingen av de intervjuade utnyttjar BIM i förvaltningen. Företagen strävar efter att digitalisera förvaltningen, men ännu inte åstadkommit det fullständigt. Intresset för BIM i förvaltningen finns, dock har många förvaltare brist på kunskap om byggnadsinformationsmodellering. Denna studie uppmärksammar digitalisering av förvaltningsskedet och genomgår undersökning kring programvaran BIM 360 Ops som frambringar BIM i förvaltningen.
The technological development is progressing rapidly. The application of BIM (Building Information Modeling) is becoming increasingly common in the construction sector. However, the property management slips behind in the development, in comparison with the early stages of the construction process, the design and production phase. BIM in the property management stage is frequently spoken about but BIM has not yet been implemented to a greater extent. This study aims to examine how digitalized property management is at present times and if the software BIM 360 Ops can be a more efficient alternative. BIM 360 Ops is a software created by Autodesk that targets the property management stage. Through interviews with Diagona AB, Fabege, HSB, Uppsala Kommuns fastighetsaktiebolag (UKFAB), Akademiska Hus, Locum, Stockholmshem and FastPartner, an insight on how these companies are proceeding at present times, which knowledge managers have about BIM and what is lacking in the management stage is brought forward. The software which the respondents use is analyzed in order to gain a greater understanding of different workflow used in the management stage. A detailed approach of the BIM 360 Ops software is demonstrated to show how the software works and to detect any difficulties, advantages and disadvantages of the software. The result shows that none of the interviewees use BIM in the management stage. The companies strive to digitalize the management stage, but has not yet fully accomplished it. There is interest in BIM in the management stage, however, many managers lack knowledge of Building Information Modeling. This study draws attention to the digitalization of the property management stage and presents a thorough study on the BIM 360 Ops software which brings forth BIM in the management stage.

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.

The Autodesk Revit software has been increasingly used in architecture due to the advantages brought about by the incorporation of BIM technology, which combines all the information representing a real building into a single virtual model. However, its capabilities have not yet been fully explored, such as in building simulations, for which Revit lacks detailed thermal analytical features. Thus, this study aims to examine the reliability of the interoperability between Autodesk Revit 2016 and EnergyPlus 8.4.0 by using Revit models for thermal simulations in EnergyPlus, one of the most commonly used tools for this purpose. The methodology consists of case studies targeting building models based on Case 600, from ASHRAE Standard 140, and Casa Eficiente Project, located in the city of Florianópolis, Brazil. The digital models of both buildings were produced in Revit with different modelling processes (conceptual mass or building elements with rooms or spaces) and software settings. All of these BIM models were exported in IFC, gbXML and IDF file formats and later converted through the use of additional tools in order to be opened in EnergyPlus. Such files were compared with the reference model of each building produced directly in EnergyPlus, using SketchUp containing the plug-in Legacy OpenStudio, in order to check for any distortions occurring in the process of data transfer when performing model exports and conversions. This comparison was based on parameters defined for geometry, simulation settings (materials thermal properties, building use and occupation etc.) and simulation results containing outputs of monthly internal temperatures for the thermal zones of each model. The results showed variations and similarities among the different types of modelling, export processes, and file formats used, revealing that distortions in data transfer become larger the more complex the building model is. This study points out conceptual mass models from gbXML files regardless of the export mode out of Revit as a viable alternative to be used in conjunction with EnergyPlus, as they preserve the geometrical accuracy of the building, even as some Revit default settings may be transferred over, thus failing to reflect some of the aspects of the real built environment. However, it was found that Revit models in general are not recommended for these types of exports due to the resulting rework needed for correcting files. It was concluded that the interoperability between Autodesk Revit and EnergyPlus is not perfect, as their combined use allows for data transfers that make possible the thermal simulation of buildings, however, in this exchange there are distortions in the exported geometries and lack of the necessary data for correct simulation in all exported models.
O programa computacional Autodesk Revit tem seu uso crescente na prática de projetos de arquitetura devido às vantagens pela incorporação da tecnologia BIM, a qual reúne todas as informações que representam uma edificação real em um único modelo virtual. Contudo suas capacidades ainda não são totalmente exploradas, inclusive no âmbito de simulação computacional de edificações no qual o programa carece de ferramentas para análises térmicas detalhadas do ambiente construído. Portanto, este estudo objetivou analisar o grau de confiabilidade da interoperabilidade entre os programas Autodesk Revit 2016 e EnergyPlus 8.4.0, para verificar o uso de modelos digitais de edificações criados no Revit em simulações térmicas realizadas na ferramenta EnergyPlus, uma das mais difundidas para este fim. A metodologia consistiu em estudos de caso com modelos de edificações baseados no Case 600, da norma ASHRAE Standard 140, e no Projeto Casa Eficiente, localizado em Florianópolis. Os modelos digitais de ambas as edificações foram produzidos no Revit com diferentes processos de modelagem (massas conceituais ou elementos de construção com ambientes ou espaços inseridos) e configurações do programa. Todos estes modelos BIM foram exportados nos formatos de arquivo IFC, gbXML e IDF e posteriormente convertidos para a extensão suportada pelo EnergyPlus, com o auxílio de ferramentas adicionais, para serem abertos no programa. Tais arquivos foram comparados com o modelo de referência de cada edificação produzido diretamente no EnergyPlus, por meio do programa SketchUp com o plug-in Legacy OpenStudio, para verificar as distorções na transferência das informações quando foi realizada a exportação e conversão dos modelos. Esta comparação foi feita com base em parâmetros definidos para as geometrias, configurações de simulação (propriedades térmicas dos materiais, padrões de uso e ocupação, entre outros) e resultados das simulações com valores de saída para as temperaturas internas mensais das zonas térmicas de cada modelo. Os resultados demonstraram variações e similaridades entre os tipos de modelagem, de processo de exportação e de formato de arquivo utilizado, cujas distorções na transferência dos dados são maiores quanto mais complexo for o modelo da edificação. A pesquisa apontou que os modelos de massas conceituais provenientes de arquivos gbXML, independentemente do modo de exportação a partir do Revit, configuraram-se como alternativa mais viável para utilização no EnergyPlus, por se manterem mais próximos à geometria da edificação, ainda que sejam transferidas configurações padrão do Revit que podem não retratar a realidade do ambiente construído. Porém, foi verificado que, de maneira geral, os modelos digitais do Autodesk Revit não são recomendados para esse tipo de exportação devido ao retrabalho diante da necessidade de correções nos arquivos. Concluiu-se que não é perfeita a interoperabilidade entre os programas computacionais Autodesk Revit e EnergyPlus, pois existe a possibilidade de transferência de informações para simulações térmicas de edificações, entretanto nesta troca há distorções nas geometrias e falta de dados necessários para a correta execução da simulação em todos os modelos exportados.

This diploma thesis focuses on processing and data collecting for the use of creating functional 3D informating model that we call BIM (Building Information Modelling) which is getting more and more attention throughout building industry and it is used by all of the participants in the industry from designers and architects to those who are dealing with building installations. This process is slowly getting into legislations of many countries including Czechia. The thesis is divided into two parts where one of them is describing the Building Information Modeling in general and the other part is describing the work which is behind the colleting good data which is needed when making the 3D documentation in Revit software which is wildly used for designing building constructions. Practical part of the land surveyor´s work is devided here into two parts where one of them is dedicated to collecting data by laser scanning process, GNSS and measuring by total station and levelling machine. Second part focuses on the description of the data processing in order to make 3D model. The example of the output production data is the BIM 3D model of the family house in selected level of detail and besides that we also have the visualization of both interior and exterior and 2D simplified building documentations.

BIM (Building Information Modeling) är idag ett vedertaget begrepp inom byggprojektering.En viktig styrka med BIM är möjligheten till koordinering mellan samtligaaktörer i projektet. BIM-verktygen bygger på parametrisering vilket innebär att modellensobjekt har en stor uppsättning data kopplad till sig. Objektens egenskaperkan ändras genom att justera parameterdatan. Parametriseringen medför också attdata relativt enkelt kan nås, extraheras och styras av externa program. Det är i dettasyfte som implementeringen av grafisk programmering fyller en viktig funktion. Medhjälp av grafisk programmering kan flera operationer i BIM-arbetet automatiseras.Därmed finns potentialen att spara värdefull tid för byggprojektören. Autodesk Revit är ett av de verktyg som dominerar BIM-marknaden. I Revit kananvändaren designa och dokumentera ett byggprojekt i alla dess faser. Sedan någraår tillbaka finns det ett tillägg till programmet som heter Dynamo. Dynamo tillåteranvändaren att styra Revit med hjälp av skript i en användarvänlig grafisk miljö.I denna uppsats redogörs för Dynamos möjligheter och begränsningar applicerat påväletablerade arbetsmoment inom byggprojektering. Här redogörs för optimeringspotentialenoch lämpliga användningsområden. Slutsatser som dragits grundar sig ihög grad på en empirisk undersökning där ett antal grafiska skript har skapats ochutvärderats. Resultatet visar på att fl era vitala moment i byggprojektörens vardagliga arbetsflödekan effektiviseras med hjälp av införandet av grafisk programmering. Med effektiviseringavses i detta fall primärt tidsbesparingar som bidrar till ökad ekonomiskhållbarhet för byggprojekteringsföretaget.
BIM (Building Information Modeling) is today a proven concept in construction design.An important strength with BIM is the possibility of coordination between allactors in the project. The BIM tools are based on parameterization, which meansthat the model's object has a large set of data attached to it. The properties ofthe objects can be changed by adjusting the parameter data. Parameterization alsomeans that data can be easily accessed, extracted and controlled by external applications.It is for this purpose that the implementation of graphic programming playsan important role. With the help of graphical programming, several operations inthe BIM work can be automated. Thus, there is the potential to save valuable timefor the construction projector. Autodesk Revit is one of the tools that dominates the BIM market. In Revit, theuser can design and document a construction project in all its phases. For a fewyears back, there is an addition to the program called Dynamo. Dynamo allows theuser to control Revit using scripts in a user-friendly graphical environment.This essay explains Dynamo's possibilities and limitations applied to work processesin building design. It describes the optimization potential and appropriate applications.Conclusions are mainly drawn based upon the generation and evaluation ofgraphical scripts. The result shows that several vital moments in the construction projector's dailywork ow can be rationalized through the introduction of graphic programming. Rationalizationmeans time savings that contribute to increased economic sustainabilityfor the construction company.

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.

This thesis has examined the Tekla Structures modeling software and answered the question of whether it could act as a suitable modeling program for the design department at Bjerking AB in Uppsala. The method used in this work is a case study of a previous project with existing basis to work form. The demarcation of the study was to examine only the usability of the foundations of in situ concrete.  The work examined three main areas within the design process. The first was to model the concrete elements then to model the reinforcing and ultimately production of the drawings. Because Autodesk Revit was the existing modeling program in the Department conducted the evaluation as a comparison between the two programs. The condition was that all three main parts would be made in the same program.  The results showed that Tekla Structures has great potential in the field of concrete modeling, and that it is a suitable modeling program to use for projects thats include foundations in situ concrete. The study has also shown the programs benefits to model reinforcement in 3D in these types of projects.
Detta examensarbete har granskat modelleringsprogrammet Tekla Structures och besvarat frågan om huruvida det kan fungera som ett lämpligt modelleringsprogram för konstruktionsavdelningen på Bjerking AB i Uppsala. Metoden som har använts i arbetet är en fallstudie av ett tidigare genomfört projekt med befintliga underlag att utgå ifrån. Avgränsningen i studien har varit att endast undersöka användbarheten i grundkonstruktioner av platsgjuten betong. Arbetet undersökte tre huvudområden inom projekteringsprocessen. Det första var att modellera betongelement sedan att modellera armering och till sist framtagning av ritningar. Eftersom Autodesk Revit var det befintliga modelleringsprogrammet på avdelningen genomfördes utvärderingen som en jämförelse mellan de två olika programmen. Förutsättningen var att alla tre hvududelarna skulle göras i ett och samma program.  Resultatet visade att Tekla Structures har stor potential inom området betongmodellering, och det är ett lämlpligt modelleringsprogram att använda för projekt som innefattar grundkonstruktioner i platsgjuten betong. Studien har även visat programmets fördelar med att 3D-modellera armeringen inom dessa typer av projekt.

The main aim of this master thesis is utilization of the laser scanning technology in the field of information modelling of historical objects (HBIM). The optimal workflow of creating the information model in the Autodesk Revit has been demonstrated. The workflow deals with the historical value of the object. For the purposes of this work, the object of the mausoleum Fabara has been selected. Furthermore, the master thesis focuses on the possibilities of publishing the resulting model.

Examensarbetets mål var att utforma två förslag på ett musik- och konsthus för placering i Växjösjön. Konstruktionen ämnas vara flytande och mobil.Gemensamt undersökte författarna byggnadens förutsättningar och möjligheter, i syfte att underlätta utformningsprocessen. Författarna utformade var sitt förslag. Det resulterade i två förslag med skilda arkitektoniska särdrag, skapade utifrån gemensamt stipulerade avgränsningar.Det ena förslaget är utformat med hjälp av geometriska former med raka sidor. Det kontrasterar mot det andra förslaget som har organiska och mjuka former.
The purpose of this thesis was to produce two alternative architectural designs, of a building, that will house various exhibitions and activities. Mainly those will be culture related; music and arts. The building is to be located in a Swedish lake, called Växjösjön, and the structure is intended to be placed on a floating hull.Initially the authors investigated, and discussed, what possibilities and limitations that were associated with the building. The authors then, separate from one another, created one alternative design each.The first of the two designs found its inspiration in different geometrical shapes, whereas the other was more of an organic design with a smooth and flowing architecture.
De digitala ritningarna finns att tillgå från författarna på begäran.

En stor del av projekteringsskedet är framtagandet av bygghandlingar, främst ritningar i 2D. En modernare metod är istället att samla all information om ett byggnadsprojekt i en samordnad 3D-modell, så kallad BIM-modell. Building Information Modeling (BIM) är en välkänd projekteringsmetod som bygger på att digitala 3D-modeller innehåller tillräcklig information för att beställas och produceras i fysisk form. Modellen består av parametrar som representerar olika egenskaper och när en parameter ändras uppdateras modellen automatiskt. Parametrarna kan nås och modifieras av insticksprogram, så kallade plug-ins som utökar den ursprungliga programvarans funktionalitet med hjälp av programkod. Grafisk programmering är en modern programmeringsmetod med ett visuellt gränssnitt som underlättar för oerfarna användare. Med hjälp av grafisk programmering kan parameterstyrning av 3D-modeller effektiviseras och värdefull tid sparas. Av denna anledning har Dynamo, ett plug-in utvecklat av företaget Autodesk för Revit, studerats för att ta fram ett så kallat skript som automatiserar 3D-modelleringsprocesser i Revit kopplat till placering av armering i pålfundament. Dessutom har möjligheter till standardisering undersökts, samt för- och nackdelar med metoden. I detta examensarbete redogörs för potentialen med Dynamo och de skript som skapats genom en empirisk studie. En enklare fallstudie utfördes för att kunna åskådliggöra graden av tidsbesparing gentemot motsvarande arbete manuellt i Revit. För att komplettera armeringsskripten togs beräkningsmallar fram som, enligt fackverksmetoden och Eurokod 2, försåg skripten med korrekt indata. Resultatet av projektet visar på att Dynamo och grafisk programmering kan effektivisera armeringsplacering i pålfundament. Graden av effektivisering beror på varje enskilt fall, men fallstudien visade på ca 85–90% sparad tid. En generell slutsats pekar mot att ju mer komplicerad utformning av armering desto mer tid finns att spara. Då grafisk programmering bygger på automatisering av arbetsprocesser av upprepande karaktär finns stor potential för att standardisera projektering med hjälp av dynamoskript. Företag kan då skapa rutiner som ökar kontinuitet och kvalitet i sina projekt. Automatiseringen leder även till färre mänskliga fel och utförandet blir effektivare. Uppdragsgivaren uppmanas att vidareutveckla metoden genom att implementera tydliga rutiner vad gäller 3D-modellering med grafisk programmering, samt undersöka möjligheten med automatiserad armering i andra bärande konstruktioner.
Most of the time spent on project planning is dedicated to the development of construction documents, mainly 2D-drawings. A more modern method is to gather all information about a building project in a coordinated 3D-model, so called BIM-model. Building information modelling (BIM) is a well-known design method based on a digital 3D model having enough information to enable procurement work and actual production. The model consists of parameters that represent different properties and when a parameter is changed, the model is updated automatically. These parameters can be accessed and modified through external programs, so called plug-ins that extend the original software’s functionality using program code. Visual programming is a modern programming method which utilizes a visual interface that favours users with little or no experience. Using visual programming, parameter control can be made more efficient and save valuable time. For this reason, Dynamo (a plugin developed by the company Autodesk for Revit), has been studied to create a so-called script that automates 3D modelling processes in Revit linked to placement of reinforcement in pile caps. In addition, possibilities for standardization have been investigated, as well as the advantages and disadvantages of the method. With this project, the potential of Dynamo and the scripts created through an empirical study is described, where a relatively simple case study is carried out in order to illustrate the amount of time saved through visual programming compared to corresponding work manually done in Revit. Furthermore, calculation templates were created, according to the strut and tie model and Eurocode 2, to provide the script in Dynamo with the correct inputs. The result shows that Dynamo and visual programming can make placement of reinforcement in pile caps more efficient. While the degree of efficiency is case dependent, the case study showed an overall 85-90% time saving. A general conclusion suggests that the more complicated rebar designs, the more time there is to be saved. Since visual programming is based on the automation of repetitive processes, there is great potential to standardize structural design with the help of Dynamo scripts. Companies can thus create routines that increase continuity and quality in their projects. The automation also leads to fewer human errors and a more efficient execution. The client is advised to further develop this method by implementing explicit routines regarding 3D modelling with visual programming and investigate the possibilities of automation of reinforcement design in other load-bearing structures.

A prefabricated timber frame house previously built by Villafabriken AB has been modeled in Autodesk Revit Architectural, a 3D-program based on BIM-technology. This has been done tosee if it’s possible to produce the publications that Villafabriken demands from the designengineer’s work, and examine which possible extra values that may arise compared to traditional 2D-CAD drawing.BIM is short for Building Information Modeling. Everything is stored in a single database and a change in the project file is automatically updated across the project. BIM provides more than just drawings since information from the model can be retrieved in various ways such as lists and quantity schedules.It was possible to produce the publications that Villafabriken demanded using Revit, but BIM doesn’t only mean a new way of drawing, it also require a change in the company’s process were the information from the model is being used.

BIM står för Building Information Modeling. Det är en ny teknik för att konstruera en virtuell modell av en byggnad i digitalt format. De stora fördelarna med BIM är att alla komponenter som läggs till i modellen innehåller information. Av informationen genereras automatiskt de handlingar och listor som behövs. Dessutom fås presentationsmaterial i form av 3D-modeller utan något extra arbete. Undersökningen behandlar ett företag och varför de inte genomfört en övergång från 2D-CAD till BIM och syftet är därför att visa dem vilka effektiviseringsmöjligheter som finns.

In questo elaborato ho voluto approfondite la tematica dell’organizzazione della sicurezza in cantiere attraverso la metodologia di progettazione BIM. Il BIM sta prendendo sempre più piede sia all’estero che in Italia ma spesso viene usato per progettare costruzioni intesi come edifici. Obbiettivo dell’elaborato è di espandere “lo stile di pensiero” BIM alle fasi cantieristiche che precedono la costruzione dell’edificio. Questa possibilità viene offerta, e qui approfondita, da Solibri Model Checker. Dopo un’introduzione per capire cosa si intenda quando parliamo di BIM e un successivo inquadramento normativo; ho scelto di esporre un esempio concreto, pertanto il primo passo è stato selezionare il caso di studio a cui applicare la ricerca. Usando Autodesk Revit, ho sviluppato non solo il modello dell’edificio ma anche il modello 3D del cantiere e delle diverse fasi prese come esempio (fase di allestimento del cantiere, di scavo, getto delle fondazioni e costruzione delle murature) per avere un modello completamente parametrizzato. In accordo, poi, con Harpaceas, casa di distribuzione in Italia di Solibri, è stata approfondita la conoscenza del Software per ricercarne una metodologia che si avvalga del Code Checking non solo per l’edificio, ragione per cui nasce il software, ma anche le interferenze e le problematiche inerenti alle fasi costruttive, macchine, attrezzi e rischi riguardanti il cantiere. Alla base di questa scelta c’è la volontà di applicare il pensiero BIM fin dalle fasi preliminari del progetto in ossequio ai disposti normativi in materia di sicurezza; per avere un controllo completo dei rischi e delle problematiche non solo della costruzione ma anche l’ambiente che la circonda. Grazie a questo lavoro di ricerca è stato reso possibile analizzare alcuni fattori importanti dell’organizzazione del cantiere attraverso un modello di pensiero innovativo e all’avanguardia.

Reducing and managing the environmental impacts of building structures has become a priority of building stakeholders and within the architecture, engineering and construction (AEC) community; although, conflicting approaches and methods to combat the issues are present. For example, green building standards are widespread throughout the world; however each one has its own characteristics and consequently its own specific requirements. While all have proven to be effective rating systems and have similar requirements, the distinguishing characteristic that separates them is their treatment of performance and prescriptive metrics. The feature they all severely lack or currently limit is the inclusion of strict engineering evaluation through energy simulations; hence, the reason why they fail to offer procedural steps to meet performance metrics. How can design professionals design energy efficient buildings with such constraints? Fortunately, advances in technology have allowed design professionals access to content found in Building Information Modeling (BIM). However, extracting pertinent information for specific use in energy analysis is problematic because BIM software currently available is filled with interoperability issues when placed in external software for energy analysis and energy analysis software itself is created with many assumptions that affect the tabulated energy results. This research investigates current building rating systems, determines how current professionals meet energy requirements, and prove that it is possible to create an add-on feature to Autodesk Revit that will allow design professionals to extract the needed information to meet energy goals with actual prescribed methods of mechanical systems selection and evaluation.
