The evolution of the concept of sustainable development is used as a basis for advancing understanding of sustainable construction. Principles of sustainable construction are developed and divided into four 'pillars' - social, economic, biophysical and technical - with a set of over-arching, process-oriented principles, to be used as a checklist in practice. A multi-stage framework is proposed which requires the application of Environmental Assessment and Environmental Management Systems for construction projects.Sustainable, Development, Environment, Assessment, Management,
An opinion survey of South African architects, quantity surveyors, engineers and contractors regarding ethical behaviour within the construction industry reveals that South African contractors seem to possess a reputation for unethical conduct. The range of problems encountered includes collusion, bribery, negligence, fraud, dishonesty and unfair practices. While bribery in the form of payments and gifts is prevalent, fraud does not appear to be as serious a problem. Most construction professionals believe that the industry suffers from unfair tendering practices, as well as over-claiming and/or withholding payment for service delivery. Negligence arises mainly from poor documentation and poor workmanship. Incidents of collusive tendering encompass cover pricing and bid cutting by contractors, while the primary form of fraudulent behaviour is deceit and misinformation. The Organisation for Economic Co-operation and Development's bribery codes conditions could be used to counter unethical behaviour in the construction industry.Corruption, codes of conduct, professional ethics, business ethics, South Africa,
