Application of subcontracting as a quality improvement tool for building constructions in Sri Lanka

Abstract

Research on the necessity of subcontractors’ incorporation in quality improvement in construction is scarce globally, especially in the Sri Lankan context. Thus, this research aimed to evaluate the applicability of subcontracting as a quality improvement tool for building constructions in Sri Lanka under the traditional procurement path. The qualitative approach with semi-structured interviews using experts for the data collection through three qualitative Delphi rounds was used. The collected data were analysed using manual content analysis. Selection, communication, productivity, time schedules, payments, and safety relating to subcontractors are the key elements to be considered when enhancing subcontractors’ contribution to the quality improvement of building constructions. This study fulfilled the literature gap to evaluate the applicability of subcontracting as a quality improvement tool for building construction, especially in Sri Lanka.
