DISCUSSION ON BIM IMPLEMENTATION IN PRE-ENGINEERED BUILDING (PEB) INDUSTRY

摘要

The adoption and implementation of Building Information Modeling (BIM) are still challenging for both the public and the private construction sectors. Nevertheless, studies and reports show a significant increase in the rate of BIM implementation and adoption in mainstream construction activities over the last five years as general tools and practices mature. In contrast, Pre-Engineered Building (PEB) construction, a specialized construction system, has not seen the same uptake in BIM implementation and adoption. The PEB system provides a very efficient approach for construction primarily industrial buildings, and it is due to this advantage that it has seen increased use over the last decade. This paper discusses the benefits, risks, and challenges involved in BIM implementation in PEB industry. The potential benefits and the most important challenges of implementing BIM in the PEB industry are examined by using a case study project. Given the existing nonflexible/non-BIM design process of PEB system, this paper argues that a significant amount of change orders and reworks costs could be eliminated in collaborative PEB projects (involving multiple construction disciplines) by defining a BIM workflow for the design and construction phases. In conclusion, this paper suggests a need for the development of a comprehensive BIM framework; which could be developed for PEB industry based on the similar existing BIM framework and processes used in the Pre-Fabricated building industry.
