Construction Site BIM Requirements

Construction are characterized by some overall requirements (e.g. quality, expected time and cost compliance, productivity, profitability, workers’ health and safety) to be satisfied. The necessary process to fulfil these requirements should start from the construction site design phase. The aim of the research is the implementation of construction site information in BIM models in order to support the execution phase design since the early stages of the project. These information concern, among the others, the choice optimization of site plants and equipment (i.e. construction site facilities), during the design phase. For this purpose, the creation of a BIM database of construction site facilities is needed. Each record of the database has thus to discharge a panel of BIM construction site requirements, each of them characterized by a set of physical and operational parameters whose relationships with project information lead the choices of the site designer. The methodology for the identification of these kind of BIM requirements has followed these steps: (i) definition of a set of information characterizing building elements/materials from a construction site point of view; (ii) construction site facilities identification and classification; (iii) first investigation in order to assess which is the adequate detail level of site plants and equipment graphic representation in order to create the above mentioned database. A case history is presented in order to show how BIM is useful for construction site designers to optimize their work, sharing information with the other figures involved in the construction process.
