fra Skitsebaseret Design til Computational BIM: Objektdesign med Dynamo

Abstract

Rapporten indledes med en betragtning af den danske byggebranche anno 2015. Det beskrives hvordan der med paradigmeskiftet fra 2D dokumentbaseret projektering til 3D objektbaseret, er sket en teknologisk udvikling. Der opleves imidlertid udfordringer med arbejdet med Autodesk Revit som det primære BIM-værktøj for objektbaseret parametrisk modellering. Disse udfordringer søges gennem rapporten løst med Dynamo, hvilket leder hen mod den initierende problemformulering: ”Hvordan kan Dynamo løse virksomheders oplevede problemer med bygningsmodellering i Revit og ændrer det på et eksisterende workflow ved projektering?” Gennem en problemanalyse undersøges virksomhedernes oplevede problemer og et nøgleproblem udvælges som genstandsfelt for den senere bearbejdning. Dynamo undersøges som værktøj, og der udvikles eksempler på løsning af problematikker, som argument for at det kan løses med Dynamo. Ud af analysen belyses det, hvordan man kan beskrive anvendelsen af Dynamo for en automatiseret proces, som et arbejde med Computational BIM. I forhold til traditionel projektering som en skitsebaseret proces, gives der eksempler på potentialer ved at anvende ny teknologi som middel til et optimeret workflow. Der undersøges specifikt hvordan Dynamo kan løse en opgave med at optimere et workflow omkring et dimensionerende varmetab og et automatiseret design af bygningsobjekter. Dette problem er skrevet direkte ind i rapportens endelige problemformulering: ”Hvordan kan der med Dynamo udføres et automatiseret workflow med varmetabsberegning og design af bygningsobjekter?” Resultatet af rapportens bearbejdning er udviklingen af en prototype, der besvarer problemformuleringens hovedspørgsmål. Gennem Contextual Design metoden arbejdes der med udvikling af et system, hvor konceptuelle modeller og sekvens beskrivelser anvendes som storyboard for den endelige løsning. Arbejdet med Dynamo giver en indikation af, at der ikke kræves programmeringserfaring, for at kunne udvikle simple og mindre komplicerede løsninger. Afslutningsvis konkluderes det at den udviklede prototype skaber et optimeret workflow for faggrupperne ved projektering, samt udfører en automatiseret proces af en varmetabsberegning. Prototypen skal ses netop som en udvikling af løsning, og ikke et færdig system. Kernen for løsningen har været at udføre et proof-of-concept, hvor funktionaliteten af Dynamo undersøges. Konklusionen er at Dynamo egner sig til at tage over, hvor der opleves problemer med funktionalitet i Revit. Som implementering og perspektivering omtales vigtigheden for virksomheder i at følge nye teknologier og tillære sig egenskaber for disse. Det kan betyde meget for en virksomhed, dels at være parat til mulige paradigmeskift eller nye teknologier, og dels for at give dem en competitive edge.

The report begins with a reflection on the Danish construction industry anno 2015. It describes how the paradigm shift from 2D document-based design to 3D object-based, has caused a technological development. Challenges are however experienced when working with Autodesk Revit as the primary BIM tool for object-based parametric modeling. These challenges are through the report sought to be solved by using Dynamo, which lead towards the initiating problem formulation: "How can Dynamo solve the current problems experienced by companies when using Revit for building modeling and change an existing workflow for design?" Through a problem analysis several companies experienced problems are examined from where a key-problem is chosen as a field for later processing. Dynamo is investigated as a tool, and examples of solving problems are developed that argument that it can be solved with Dynamo. Out of the analysis, it is emphasized how to describe the use of Dynamo for an automated process as a work in Computational BIM. Compared to traditional design as a sketch-based process provides examples of the potential of using new technology as a means to an optimized workflow. It specifically examined how the Dynamo can solve a problem of optimizing a workflow around a dimensioning heat-loss and an automated design of building objects. This issue is written directly into the report's final problem-formulation: "How can Dynamo be used to perform an automated workflow with heat-loss calculation and design of building objects?" The result of the report processing is the development of a prototype that answers the problem-formulation main issues. Through the use of Contextual Design methodology a system in which conceptual models and sequence descriptions using as a storyboard for the final solution is developed. Working with Dynamo gives an indication of that no programming experience is required in order to develop simple and less complex solutions. Finally, it is concluded that the developed prototype creates an optimized workflow of professions by design, as well as performing an automated process by a heat-loss calculation. The prototype should be seen just as a developing solution, and not as a complete system. The core of the solution has been to perform a proof-of-concept where the functionality of Dynamo is examined. The conclusion is that Dynamo is suited to take over where functionality problems are experienced in Revit. As implementation and perspectives discussed the importance for companies to follow new technologies and learning compulsive, their properties. It can mean a lot to a company and to be prepared for possible paradigm shift or new technologies, and partly to give them a competitive edge and.
