Subcontractors, quality of work, flexibility, construction industry, rework


Every stakeholder’s intention in a project is to have the best quality and minimize rework. But there are  hurdles that come up during the stages and processes of a project that can compromise the quality if not handled correctly. This study aims to identify the influencing factors that affect subcontractors’quality of work and the impact of flexibility. Construction professionals from Poland and Nigeria participated in the survey. Descriptive statistics using IBM SPSS software version 27 was used to analyse the data.

The results obtained shows that there are several variables influencing subcontractors’ quality of work, the overall ability of the subcontractor to ensure that the project meets the basic function of the end user's needs and intents, the degree to which the construction operations meet the design standards and specifications, strict adherence to quality assurance plan on general performance, subcontractor's ability to complete the contract on the completion date and the ability of the subcontractor to carry out the construction work with little rework, were identified as the major factors that affect the quality of work. Further analysis shows that the impact of flexibility on the subcontractors’ quality of work could increase the smooth operation of the construction processes, increase compliance with the quality specifications, helps in effective decision making and effective functioning, limit non-conformities between planning and realization of work, and reduction in rework errors. The main contractors sometimes substitute or chnage the subcontractors. This study identify poor quality of work, failure to meet the deadline, use of inappropriate material and non-conforming to quality standards as some of the reasons for this change.
