Implementation of Building Information Modeling (BIM) in Modular Construction: Benefits and Challenges

TLDR

Modular construction builds prefabricated units offsite, offering workforce savings, lower GHG emissions, faster schedules, and higher quality, but requires extensive pre‑project planning and cross‑disciplinary coordination. The study explores how Building Information Modeling can address these coordination challenges. Case studies show that BIM implementation in modular construction yields clear benefits and also reveals specific challenges.

Abstract

Modular Construction consists of one or more structure units fabricated in a manufacturing plant away from the jobsite. In the building industry, prefabricated modules are normally completed with trim work, electrical, mechanical and plumbing installed. Previous studies have proved that Modular Construction provided many advantages to the built environment, including the reduction of need for workforce, the reduction of onsite Green House Gas (GHG) emissions, and the improvement of construction schedule and product quality; however the extensive demand of pre-project planning and coordination among members of cross-interdisciplinary professionals have significantly impeded the application of this technique. With the recent development of Building Information Modeling (BIM), these challenges could be overcome through the BIM platform. Through case studies the benefits and challenges of implementing BIM in modular construction are clearly identified.
