Perception of Consultants and Contractors to Performance Factors of Construction Projects

Abstract

Due to various problems and challenges of construction industry especially in the production and delivery of sustainable infrastructure, performance of construction projects has become an issue of concern not only to contractors and professionals but other stakeholders including clients, project sponsors and end-users. This is due to complexity of construction process, innovation in the use of raw materials and machinery, new construction management techniques and more importantly, change in the demand of clients. Thus, this research evaluates performance indicators for construction projects from the perspective of consultants and contractors. This is to improve construction project performance with a view to enhancing the quest of construction industry of contributing positively to the economy and overall growth of the nation. Using quantitative approach, data were collected through close-ended questionnaires administered on a group of learned consultants and contractors with sufficient knowledge and experience of the construction industry. From the analysed data, there is a significant difference in the perceptions of consultants and contractors regarding factors affecting performance of construction projects. To consultants, general time factors and conformance to specification are the most important performance indicator for project success while from contractors’ view, cost factors including delay in payment from owner to contractor is a major critical success factor. The two groups unilaterally agreed that bringing about the best planning and scheduling technique before and during construction would assist in improving performance of construction projects in the country.
