Operational Delay Factors at Multi-Stages in Thai Building Construction

Abstract

This paper presents the results of a survey carried out to investigate the severity index in terms of impact level and occurrence frequency of operational delay factors for high-rise building construction in Thailand. The construction phase is divided into five major stages namely piling, structural, architectural, electrical and mechanical (E&M), and sanitary stages. A process for factor identification was rigorously designed to ensure the comprehensiveness and reliability of the factors in each stage. Respondents were carefully selected from Construction Management (CM) consultants and general contractors with a minimum working experience of ten (10) years in the building construction sector. The delay factors were analysed and ranked according to their severity index. This facilitated the comparison of perceptions of the CM consultants and general contractors on delay factors at each construction stage. The factors were also thoroughly examined to determine the critical factors at each stage. It is expected that the critical factors identified in this survey would serve as a warning light to prevent operational delay factors in the building construction sector in the future.
