An investigation on the impact of subcontracting system on the eventual quality of construction facilities in Swaziland - an exploratory study

Abstract: The construction industry is a key sector in the development and economic growth of Swaziland, however, the industry has not escaped the challenges facing other countries worldwide in terms of delivering construction projects of good quality as stipulated in the contracts. This paper assess the extent to which subcontracting in Swaziland has contributed to the apparent poor quality workmanship in the construction industry. The data used in this paper were derived from both primary and secondary sources. The secondary data was collected via a detailed review of related literature. The primary data was collected through a well-structured questionnaire which was distributed to construction stakeholders namely: Contractors, Sub-contractors, client (Government), Consultant representatives (Quantity Surveyors, Architects, Civil engineers, Project Managers and Electrical and mechanical Engineer). Only organisations registered with the ministry of public works and transport in Swaziland and other professional bodies were surveyed.100 questionnaires were distributed and 80 were completed and returned and used for the survey, it represented 80% response rate. Data received from the questionnaires was analysed using descriptive statistics procedures. Key findings from the study revealed that the major factors affected by subcontracting are poor quality, material wastage,high level of reworks and level of disputes and conflict. Major factors contributing to poor quality problems in costructed facilities were the superior/subordinate relationship, delayed payment from main contractor, poor relationship betwen main contractor and lack of subcontractor training. Findings on how quality can be improved in subcontracted projects were skilled workforce, training and education, good communication between parties and management commitments were major key. Investigating the extent to which subcontracting in Swaziland has constributed to the apparent poor quality workmanship in the construction industry will provide knowlegde on the problem and hence the study
