Constructability practices in construction industry in Muscat: case study

This study aims to review the concept of constructability and evaluate the level of implementation of constructability practices in the construction industry in Muscat Governorate. One hundred and ninety questionnaires were distributed, and 85 complete responses were received, including 10 from owners (12%), 64 from consultants (75%) and 11 from the contractors (13%). The results showed that owners, consultants, and contractors recognize, support, and practice constructability efforts. 45% of the respondents said that constructability efforts typically begin in preconstruction planning, which shows a positive awareness that constructability efforts must start at the earliest stage of a project’s life cycle. In addition, 60% of the respondents indicated that they performed constructability by following a constructability procedure during the design stage. All the respondents agreed that constructability implementation obstacles continued to exist in construction projects in Muscat and the cost and time associated with the implementation of constructability review practices are the most dominant obstacles. Although constructability has been recognized in Muscat’s construction industry, the level of constructability awareness and improvement in cost and time estimation and quality requirements are developing.
