Identifying waste in virtual design and construction practice from a Lean Thinking perspective: A meta-analysis of the literature

Abstract

In recent years, the Architecture, Engineering, and Construction (AEC) industry has broadly expanded the use of Virtual Design and Construction (VDC),
particularly Lean Construction methods, to deliver value to their customers. VDC includes the use of Production Management using Lean methods as an
integral part of the defining theory and method, and multiple case studies have concluded that the greatest performance improvement is achieved by
implementing both initiatives together. This paper reviews extensive literature of VDC and Lean Construction with the intent to show benefits in the
application of Lean Construction in the actual practice of VDC and to provide examples of waste and opportunities for improvement in projects if Lean
methods are applied. This study found that use of Lean methods can help to reduce waste within the VDC process, in the phase of information flow
(process view). Specifically, our main finding from this study was that only five types of waste represent 80% of the referenced occurrence of waste in
VDC processes, which suggests that if teams use Lean Methods and focus on elimination of these types of waste (i.e., motion (excess), inventory (excess),
overproduction, waiting and employee knowledge (unused)), teams can improve VDC practices dramatically.
