Analysis of the Implementation of VDC from a Lean Perspective: Literature Review

Abstract

VDC (Virtual Design and Construction) models are seen as an important tool in the AEC (Architecture, Engineering and Construction) industry. The VDC methods allow stakeholders to integrate and transmit information throughout the project life cycle, in order to meet customer requirements. Furthermore, VDC is seen as a new approach that will help the AEC industry in achieving Lean principles by eliminating waste, reducing costs, improving productivity and creating positive results within the projects. The Lean philosophy can be used as a conceptual framework for the implementation of VDC, because the impacts of VDC can be associated directly with Lean Principles. Despite the importance of VDC, its implementation is based on anecdotes and beliefs from past projects making it difficult for the industry professionals to formalize implementation lines (factors and metrics) and apply them throughout the project. This research aims to analyze the current implementation of VDC from a Lean perspective. Our analysis includes studies – in the form of surveys, interviews, case studies, literature reviews and implementation guides– that have been conducted in order to assess the implementation and impact of VDC in the AEC industry. The results highlight the importance of the VDC implementation (benefits and obstacles), the lack of tools to identify strategies for successful implementation and the connection between VDC and the lean philosophy.
