Purpose - This paper is aimed at identifying the common approaches for improving constructability and evaluating their effectiveness of implementation. Design/methodology/approach - A comprehensive survey has been carried out on contemporary literature, i.e. from 1990 onwards, to trace the development of the buildability and constructability concepts and the common approaches of improvement. Findings - Results show that buildability is mainly concerned with design, quality of built products, ease of construction, as well as efficient and economical construction. Constructability emphasises integration of construction knowledge and experience at various project stages; optimisation of different project requirements to achieve overall goals; and ease of construction. Therefore, "constructability" embraces the concept of "buildability". The implementation of Quantified Assessment, Constructability Review and Constructability Programmes are the three commonly adopted approaches. Practical implications - Improvement measures should be implemented at the design stage, whereas improved constructability would eventually bring about tangible benefits in terms of time, cost, quality and safety. The Quantified Assessment approach appears to be the most practicable way of improving constructability. Originality/value - Up till now, there have been very limited studies providing an evaluation of different approaches for improving constructability. The study has offered an insight into the commonly adopted improvement measures, highlighting proven success cases, hence enabling effective strategies to be developed for enhancing constructability.
