ROLES OF QUANTITY SURVEYORS IN THE SUSTAINABILITY OF THE CONSTRUCTION INDUSTRY

The construction industry is increasingly under scrutiny for its environmental impact, prompting a shift towards sustainable construction practices. Despite their pivotal role in cost management, Quantity Surveyors (QS) have been acclaimed to have limited participation in enhancing sustainable construction practices. Hence, this study investigates the role of QSs in promoting sustainable construction (SC) and the challenges they face in advocating for sustainable construction within the South African industry. The study employs a qualitative research methodology, utilizing semistructured interviews to capture in-depth insights from experienced QSs. A purposive sampling technique was adopted, targeting ten QS professionals with at least three years of industry experience. Data was collected through interviews and analysed using thematic analysis, identifying key trends and perspectives. Findings revealed that QSs can integrate sustainable construction principles into cost estimation, financial feasibility studies, and life-cycle costing (LCC) to encourage eco-friendly investments. However, challenges such as clients’ preference for short-term savings over long-term sustainability benefits and the slow adoption of green materials due to supply chain constraints hinder their efforts. The research also high-lights the need for regulatory support and continued professional development to equip QSs with expertise in green building materials, energy-efficient technologies, and sustainable procurement strategies. The study underscores the necessity for collaborative efforts between QSs, architects, engineers, and policymakers to drive sustainable construction. It recommends policy interventions, client education on sustainable benefits, and enhanced training in sustainability for QSs to bridge the existing gaps.
