Abstract
This chapter investigates the difference in productivity performance between green and conventional construction projects, the significant factors affecting the productivity of green construction projects, and some feasible solutions to improve green construction productivity. The findings of this chapter reveal that green construction projects have experienced productivity issues and that the delays caused by these issues occur more frequently than in conventional construction projects. The findings also show that only 22.0% of conventional construction projects have encountered productivity issues, while green construction projects almost doubled that figure to 42.8%, with the percentages of the project delays caused by productivity issues being 54.2% and 77.3% for conventional and green construction projects, respectively. This chapter further identifies the top five productivity factors for green construction projects, which are “workers’ experience,” “design changes,” “technology,” “workers’ skill level,” and “planning and sequencing of work.” In addition, the results of this chapter indicate that “standardized design,” “investment in new tools and equipment,” and “consultants’ or superintendents’ on time checking, receiving and approving of design documents” are the top three useful solutions for improving productivity in green construction projects.
