Development and analysis of an automated performance code checking workflow

Abstract This study aimed to evaluate the applicability, accuracy, and challenges involved in the automated checking of design requirements specified by a Performance Code (PC) using a BIM (Building Information Modeling)-enabled model checker software application. Specific goals include: (a) definition of a workflow for the parameterization of a set of computational rules addressing part of the PC design requirements, (b) testing and evaluation of the proposed parameterization using a BIM model of a real large-scale housing project, and (c) comparison of accuracy and checking times between manual and automated methods. The research team developed and tested the automated checking of approximately one-third of the requirements. Findings indicate a substantial checking time decrease and an increase in the number of nonconformities detected through the automated method in comparison to the traditional technique of compliance assessment.
