Industrially inspired A-planning using parameterized room objects (engelsk)
Abstract [en]

The digital wave that has engulfed the construction industry has in many ways changed how consultants work. The new working methods have created new conditions and opportunities for how architectural planning in construction can be conducted. Traditional planning is a project-oriented ETO process that can be compared with manufacturing of complex one-of-a-kind products (Jensen, 2014). Many consultants' business models based on the process gets criticized for not encouraging the reuse of solutions or development of their ways of working (Lidelöw, Stehn, Lessing, & Engström, 2015).

In the manufacturing industry, processes based on the concept of mass customization are used. The purpose of these processes is to improve the flexibility of the final product, at the same time as the standardization and economies of scale is preserved in the components (Jensen, 2014). Modularization and configuration is central within mass customization. These concepts along with automation formed the basis of the study. The concept intended to incorporate these influences into traditional A-planning, is called room objects. Room objects are parametrically driven objects that collect furnishings and equipment as modules in a BIM environment. In this study the room objects has been developed as products families with the intention and ability to meet the underlying needs (Jiao, Simpson, & Siddique, 2007). The needs consisted of room layouts gathered from reference projects and regulations and have been identified through case studies. The needs have then been revised in stages to ultimately result in the design parameters used in the construction of the room objects. In this thesis, the development of the room objects has been delimited against WC environments.

The technical use of the objects has been studied within the concept room objects. The result of the study is presented as a methodology for the use and management inside Autodesk Revit. A big part of the use consists of various tools in the form of scripts developed in the software Dynamo. The tools allow some operations within the use, and thus within the planning, to be automated. They also enable the creation of configurators outside of Revit that facilitates the configuration of the room objects.

The analysis and evaluation of the flexibility and usability showed of the room objects, shows that room objects as concept has the potential to work in the phase of A-planning. The flexibility and modularity of the room objects could within the context of the work meet 97 % of the designs given by reference projects and 100% of the designs given by the regulations. The limits of the adjustment possibilities are situated in complex room shapes that require an advanced parametric basis. The usability of the objects appeared to be limited by technical knowledge. The configuration of the room objects requires an insight of the parametric construction. The modification of the room objects requires the user to possess an understanding of parametric modelling at family level in Revit. The alteration of the scripts demands knowledge of visual programming. The potential is there to solve or manage these limitations through technical means and suitable project organization.

How the concept can be implemented purely in terms of the process should be further investigated. In this study, there has been a discussion of how the project group can be organized in order to fully utilize the benefits room objects can bring in terms of time savings, experience feedback and quality assurance.
