D.Ing. / The construction industry has changed dramatically over the past thirty odd years. The following factors played a significant role in this change: (1) The building boom around the 1970s pressurized the industry to work faster. This was followed by periods of variation in workload, which have over the last number of years manifested in a permanent low demand for construction in South Africa. (2) Projects became larger and more complex. (3) An over-regulated labour environment not only leads to the downsize of organizations, but is a main contributor towards the increased use of subcontracting. (4) The time value of money causes owners to specify compressed project schedules and lowest price is often the only selection factor in the award of contracts. The shift in work from predominantly public sector towards the private sector, which by nature is more time conscious, is another factor pressurizing the industry to work faster. The industry has introduced amongst others the following measures to cope with these demands: (1) Main contractors are subcontracting more and more of the work. (2) The traditional in-series concept came under pressure - the management approaches became formal procurement concepts and design-build re-appeared. (3) New construction techniques such as fast-tracking and the movement towards factory produced elements in certain areas, for example precast concrete elements, reduced project schedules and replaced previously time consuming activities and counteracted to a certain extent the shortage of skilled tradesmen. The author argues that in the process to combat these external pressures, the following problems, amongst others, manifested: (1) Ineffective project procurement. (2) Unethical and unsound practices between main contractors and subcontractors. (3) Lack of quality and reliability of a substantial share of end-products. Another problem burdening the industry is historical, namely cultural differences between designers and contractors.
