Building information modeling: A new frontier for construction engineering education

Abstract

Building Information Models (BIM's) are 3D parametric, virtual representations of the built environment. These models can contain the same amount of information as present in an actual building. They are also capable of representing specific details to facilitate extended analysis as needed ahead of construction. For example, all the performance parameters of specific materials such as concrete masonry units or fabricated structural steel are linked to particular installations within the BIM. This allows for the possibility of integrated engineering design such as finite element analysis. Consequently, as BIM technology progresses and improves, it has important implications for the practical and educational aspects of construction engineering. This paper explores the link between BIM implementation and onsite construction activity as experienced in a classroom setting. Starting with the design of a 36-unit multifamily residential project, students used BIM software to avoid conflict and enhance coordination ahead of actual construction. Live cost data were used to guide and inform the design process. This allowed students to make changes to building assemblies and components with an understanding of overall cost and schedule impact. Importantly, cross-discipline integration between design and construction dramatically decreased the time needed for cost estimating, planning and scheduling. It also facilitated reductions in consultant billings for specific civil, structural, and MEP design services. Through a case study approach, this paper validates the use of Building Information Modeling as an integrated format for construction education. It demonstrates the advantage which a comprehensive interface can provide to an engineering student; one which depicts the integration between design and construction services. In such an environment, students are able to simultaneously comprehend both how the building is designed, and how it will be constructed. While additional research regarding the use of BIM's is underway by the authors, the findings contained herein point towards a larger role for its use in future projects and education. © American Society for Engineering Education, 2007.
