Causal modelling construction project performance

This research concerns a quantitative examination of the causal effects of the antecedents of project performance. Congruous with a multivariate perspective, project performance has been conceived as a function of the external and site environments, the project site organisation-and-management and site personnel. The conception has culminated in a postulated partial causal model grounded on a priori conceptual-theoretical considerations. Verification of the causal model demands the testing of a network of eleven causal hypotheses using the path analytical technique. Mixed results have emerged with six causal hypotheses supported, one partially supported and the remaining four unsupported by data. The implications on policy decision making by site management have been considered. The assertion is that manipulative actions on the site integrative mechanism, on-the-spot task structuring and perceived site environmental uncertainty, conducted within a synergistical framework, would impart a cumulative promotory effect on project performance.
