Most of the construction projects undertaken are more complex in nature, demanding greater
skills and technologies. In the past two decades, subcontracting has been utilized extensively in
construction industry. Hence, subcontractor is a key person to assure the success of a construction project
although many issues involved in subcontracting practice and rarely acknowledged. The reliance of ma in
contractors on subcontractors to execute major portions of construction work makes the success of
construction projects highly susceptible to the performance of subcontractor organizations. Early
researches picked out those subcontractors are not being fully utilized due to various issues. As a result,
subcontractors are subjected to put tremendous pressures on project performance in terms of quality, time
and cost in construction industry. Therefore, in construction industry, there is a gap between the required
performance level and the current performance of subcontractors. Thus, this study attempts to fulfill the
gap between required and current performance of subcontractors by investigating subcontractors’ issues
on the project performance in terms of t ime, cost and quality. Literature review indicated number of issues
with subcontractors that had adversely influenced the performance of a construction project. The study
was adopted survey approach to fulfill the research objective. The structured questionnaire which was
developed by supporting literature findings was distributed among main contractors and sub-contractors.
Relative Important Index was adopted to analyse and evaluate the collected data. The results revealed that,
selection method, critical site coordination, labour migration, delay payment and site safety wer e
respectively significant on subcontractor performance. Further, it was identified there is a positive
relationship between attitudes of main contractor and subcontractor. The paper describes the mitigation
measures that could be used to maximize the performance of construction projects in terms of time, cost
and quality, while enhancing the performance of subcontractors
