This paper deploys value stream mapping (VSM) as a lean methodology to investigate and compare the process differences between a Canadian precast project and a Chinese precast project as a basis for improvements in reducing process waste.

This paper presents an Agent-Based and Discrete-Event model that allows project controllers to simulate current or future project states within the Weekly Work Plan (WWP) of the Last Planner System (LPS) in order to orient the project activities and performance as desired.

The client plays a vital role in driving and setting the project framework thus greatly influencing the successful implementation of lean. This study aims at identifying the status of the characteristics, behaviors and practices of Middle Eastern construction clients.

What are the attributes that affect value generation, enhancement, and optimization on projects? The research conducted in this paper shows that project value is not easily understood, it is connected to multiple attributes that shape the dynamic and evolving nature of value.

Since the introduction of the Transformation, Flow, and Value (TFV) theory, the lean construction community has widely invested in research to understand and analyse effectively the concept of value in design and construction. This paper thus aims at exploring and assembling the different attributes influencing value in construction.
