Abstract
Performance of construction projects is 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, variation in requirement from clients. Thus, this
research evaluates factors affecting performance of construction projects from the perspective of
consultants and contractors, in order to enhance the quest of the construction industry in
contributing positively to the growth of economies. Using quantitative approach, data were
collected through close-ended questionnaires administered on a group of learned and experienced
consultants and contractors who are based within the study area. 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.
