PERFORMANCE OF SUSTAINABLE CONSTRUCTION PROJECTS: A CONTRACTOR’S VIEWPOINT

Achieving stakeholder satisfaction and attaining the objectives are considered indicators of success in construction projects. Performance criteria may consist of one or more indicators influenced by project's stakeholders and characteristics. This study uses an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to determine the key indicators affecting project performance from the contractors’ viewpoint. A set of 120 structured quantitative questionnaires survey were distributed to actively registered G7 contractor companies in Pulau Pinang. Ten hypothesized factors consisting of 42 indicators were measured using a five-point Likert scale and subsequently analyzed using SPSS software. Results of EFA showed eight re-evaluating affected factors of construction project performance in Pulau Pinang; most notably, factors such as Labor, equipment, consultant, and contract (LCC) which consists of fifteen indicators, giving factors loading of 0.495 to 0.804, Eigenvalues (20.5), and variance (48.9%). Based on stakeholders’ perspective, CFA identified four statistically significant project performance factors: LCC, People, Time, and Project characteristic with factor loading and covariance values > 0.7 and < 0.8, respectively. By pinpointing these factors and validating them via a dual-phase statistical approach, this study provides actionable insights for enhancing performance in sustainable construction projects, offering practical value to stakeholders and contractors in similar contexts, particularly during difficult situation in project delivery.
