An Integrated Construction Management Approach for Addressing LEED Project Challenges

Abstract

Notwithstanding the progress that has been made in the Leadership in Energy and EnvironmentalDesign (LEED)

A conceptual model of subcontractor development practices for LEED projects

“…In order to improve the environmental performance of buildings, LEED rating systems provide four building certification levels (namely, platinum, gold, silver and certified) that meet six credit categories, namely, location and transport, sustainable sites, water efficiency, energy and atmosphere, materials and resources and indoor environmental quality (USGBC, 2013). However, due to the evolving nature of the LEED process, SC risks result in delays, cost overruns and inability to obtain LEED certification (Ofori-Boadu et al , 2016a, b; Li et al , 2011; and Anderson, 2012). This is because SCs do not understand LEED requirements and are unwilling to invest additional resources for success (Ofori-Boadu et al , 2016a, b).…”

This is because SCs do not understand LEED requirements and are unwilling to invest additional resources for success (Ofori-Boadu et al , 2016a, b). The delivery of capability of GCs is highly dependent on SC performance, particularly for projects with additional environmental performance requirements such as LEED projects (Fagbenle et al , 2018; Ofori-Boadu et al , 2012).…”

“…LEED commercial rating systems include the following: building design and construction, interior design and construction and operations and maintenance. Due to the evolving nature of the LEED certification process and the learning curve associated with LEED project delivery, SC risks result in delays, cost overruns and inability to obtain LEED certification (Ofori-Boadu et al , 2016a, b; Li et al , 2011; and Anderson, 2012). Ofori-Boadu et al (2016a, b) noted that SCs are the primary source for both technical and managerial challenges associated with LEED projects because they did not understand LEED requirements and are unwilling to invest additional resources to ensure LEED project success.…”

Nevertheless, with the global push for green built environments, successful GCs need a network of high-performing SCs to ensure LEED certification is achieved within pre-defined quality, budget, time and environmental performance targets.…”

“…Hollobaugh (2011) and Ofori-Boadu et al (2016a, b) noted that contractors should protect themselves and minimize SC risks on LEED projects through: additional prequalification requirements; extensive LEED project documentation; inclusion of LEED-specific clauses in SC agreements; implementation of LEED checklists and standard procedures and LEED-specific onsite training. SCs with a good working understanding of the LEED certification standards and a plan for achieving these standards will be better prepared to meet LEED project needs and be more attractive to GCs engaged in the development of green buildings (Tijsseling, 2009).…”
