Determining The Effects Of Adopting
Green Construction Site Practices On
Project Performance In Nigeria.
PhD thesis, Universiti Sains Malaysia.
Abstract
The negative effects of traditional construction practices on the environment
has resulted in increased advocacy for green construction site practices to be adopted
in developing countries. Despite the advocacy for the adoption of green construction
site practices, the rate of adoption is still low and this has been attributed to
uncertainties regarding project performance, and lack of attention given to project
complexity. This study is aimed at determining the effects of adopting green
construction site practices on project performance taking into consideration project
complexity. The deductive research approach was adopted using correlational research
design, and the survey method was used for data collection. The questionnaires were
self-administered. Non-probability sampling technique was used in this study for a
population of 227 projects and 168 usable responses were collected with a response
rate of 78%. The collected data were analysed using descriptive statistics (mean score)
and the partial least squares-structural equation modelling. All the green construction
site practices had high rates of adoption. It was observed that all the green construction
practices studied had significant effects on project performance of construction
projects except for site layout planning and development. The findings also indicate
that project complexity moderates 2 out of the 6 hypothesized moderating relationships
but weakens the relationship. The highest moderating effect is the effect of project
complexity on the relationship between stormwater management and project
performance.
