Abstract
Engineering errors (e.g., missing information and ambiguities) in isometric drawings result in significant labor productivity loss and schedule delays in industrial modular construction projects. Given this background, this paper aims to assess the influence of requests for information (RFIs) on module construction duration using computer simulation. In particular, pipe installation tasks are of interest in this paper due to the large number of RFIs related to pipe designs occurring in many modular construction projects. A hybrid modeling approach combining discrete event simulation (DES) and continuous simulation (CS) was used to model the piping work of a module construction project in Alberta, Canada, considering the impacts of RFIs on construction duration. Through simulation, it was assessed that RFIs will increase the piping work duration by 8% on average on the most-likely scenario of the project.
