Reinforced concrete construction entails substantial support work and formwork activities, which expose workers to, inter alia, work at elevated heights, ergonomic hazards, and hazardous chemical substances. Furthermore, support work and formwork are required to support and or restrain substantial loads and forces, is dependent upon a range of resources, and is influenced and contributed to by a range of stakeholders. Consequently, the integration of design and construction, scientific designs, the implementation of documented Quality Management Systems and H&S programmes, and optimum appropriate education and training are essential. Certain categories of problems relative to support work and formwork such as damaged components, inadequate design, and inadequate erection are experienced more frequently than others; GCs adopt an informal approach to support work and formwork; in general, recommended support work and formwork interventions can be deemed to be taken between rarely to often / often; although scientific calculations can be deemed to be undertaken, not all support work and formwork designs are scientific; quality management is more informal than formal; contractors management and supervision contribute more than designers to overall quality assurance; designers do influence support work and formwork; contractors management and supervision contribute more than designers to design, quality assurance, quality control, and maintenance of support work and formwork; GCs experience support work / formwork and structures related problems infrequently as opposed to frequently, and support work, concrete, and H&S problems do occur. Recommendations to realise an improvement in performance include: supervisory training courses; safe work procedures; implementation of documented Quality Management Systems and H&S programmes, and the development of codes of practice.
