Optimized structural design of Plug &amp; Play Core© modular stadia during preliminary design

Modular construction is the on-site assembly (installation and connection) of factory made units (Lawson et al., 2014). It allows fabrication of structural components to be moved from the building site to controlled environments. Ballast Nedam adopted modular construction as a key business strategy for the future (Ballast Nedam, 2014). Plug & Play Core is the modular and reusable structural core of a stadium. After realization, the inner core of the stadium can be easily disassembled, transported to another location and reused. Various stadium layouts can be realized, making the concept easily adaptable to the (varying) demands of the client/architect. The Plug & Play Core structural design needs to be easily adaptable to changing (tender) demands. At the same time the design process needs to be quick(er), resulting in more time for actual integral design. The design itself should primarily comply with safety codes, while the financial consequences of structural design decisions on other integral design aspects should be clear. An optimized design process in the form of a structural design tool is proposed to solve these challenges. The design tool should integrate FEM software for structural verification. First a literature search is performed to obtain necessary background information. After, a short summary of key design aspects regarding Plug & Play Core is presented. Then the design tool called Toolbox is explained in the form of a design manual. The main part of the report is ended with a case study of a demountable upper tier for the FIFA WC2022 Al-Wakrah stadium in Qatar. In that chapter the Toolbox design tool is applied to real project data. It is found that the integral design process of Plug & Play Core modular stadia can be optimized by the use of a design tool like the Toolbox. Early-stage consideration of full life-cycle design aspects via a cost analysis in combination with standardized structural analysis, makes the design process quick(er) and allows the designer to generate various design alternatives in a relatively short amount of time. This results in more time for integral optimization of the design. The case study insinuates that cost savings could be achieved by application of the Toolbox, making Plug & Play Core modular stadia more appealing regarding traditional construction alternatives.
