Global concerns over climate change and sustainability have
spurred the need for green buildings in the construction
industry. In Singapore, all new buildings and major building
renovations should achieve the minimum Green Mark standard,
as mandated by legislation in 2008. Since project managers
play an important role in the success of construction projects, it
is therefore essential to identify the critical knowledge and
skills that a project manager needs to effectively execute a
green construction project. As a result, the objectives of this
study were (1) to identify the essential knowledge and skills
required to be a competent project manager of green
construction projects; (2) to discover the challenges that project
managers encounter in managing green construction projects
and determine critical knowledge areas and skills that can
respond to the challenges; and finally, (3) to provide a
comparison of critical knowledge areas and skills between
traditional and green construction projects.
