Abstract
The construction industry has been associated with deteriorated and
adversarial working relationship among supply chain partners. This has been
reported to affect the industry performance in terms of cost. In other word, projects
attained significant cost performance through working relationships of the supply
chain (SC) partners in construction. This study aimed at developing a model for the
mediation role of ethical practice on a relationship between relationships quality (RQ)
and cost performance of Multifarious Infrastructure Projects (MIPs) in Nigeria. Four
main attributes of RQ were identified from extent literature as trust, commitment,
teamwork and performance satisfaction (PS). The study introduced ethical practice as
a mediating construct with two-dimensional measure as pre-contract ethical practice
(PreCEP) and post-contract ethical practice (PoCEP) to mediate the relationship
between RQ as the independent variable (IV) and cost performance (CP) as the
dependent variable (DV). Using purposive non-probability sampling technique, 289
valid quantitative sample data were collected. The study focused on key informants
such as directors and managers within several organizations involved on multifarious
infrastructure projects (MIPs) in Nigeria.
