A study of measures to improve constructability

Abstract

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.

Contribuição ao estudo de medidas para melhoria de construtibilidade no processo de projeto de empresa construtora

“…Como parte da análise das questões de construtibilidade na empresa, apresentam-se resumidamente abaixo algumas das diretrizes de construtibilidade atendidas pela construtora, conforme são apresentadas na literatura (WONG, 2007;AMANCIO, 2010;), e as mesmas são comparadas com a postura da empresa estudada dentro do processo de projeto:…”

“…De maneira sintética, o trabalho parte da noção de construtibilidade conforme apresentado por Wong, et al (2005), para quem o conceito é apresentado de maneira demasiadamente ampla na literatura recente, e sugere que medidas associadas ao processo de projeto das edificações configurem um aspecto específico dos problemas de construtibilidade. Nessa linha de raciocínio, Rodriguez e Heineck (2003), indicaram critérios de melhoria de construtibilidade que podem ser adotados na etapa de projeto, destacando a necessária integração entre projeto e obra.…”

Status of Industrialized Building System Manufacturing Plant in Malaysia

“…However, the concept of constructability started in the late 1960s to integrate the optimum use of construction knowledge and experience in the conceptual planning, detail engineering, procurement, and conduct field operations in phases to achieve the overall project objectives; and ease of construction [5]. The constructability concept has been extensively developed and applied in US, UK and Australia as well as in Malaysia where numerous studies have proved that constructability concept manage to save cost and time in the process of completion of the projects [6][7][8].…”
