Constructability Concepts and Enhancement Capabilities of Construction Site Team Members in Obafemi Awolowo University, Ile-Ife, Nigeria

Abstract

The application of constructability principles is as important as the principles themselves, and the construction site is where the application can be carried out. The integrated efforts required to improve constructability on construction sites can be derived from project members’ team work. Constructability is a team effort making it imperative to have the team collectively define constructability challenges, opportunities and solutions; owing to the need to share construction innovations within and across site team members. In spite of this, few researches have been done related to constructability enhancement at the construction stage by the construction site team members. To address this, a total of 60 questionnaire were administered to site team members on construction sites in Obafemi Awolowo University with a response rate of 70%. Percentage frequency was used together with Relative Importance Index (RII) to analyse the data that was collected. Findings show that respondents have practical knowledge of constructability concepts and are capable of implementing them on construction sites. Effective planning of access to site ranked 1st with RII of 0.929 among the technical capabilities of the respondents; and also the capabilities of site engineers and resident builders to keep progress and quality management records ranked 1st among their constructability enhancement capabilities.

Keywords: Constructability, constructability concepts, constructability enhancement techniques.
