An Investigation Into The Use Of Building Information Modelling And Its Impact On Construction Performance Within Ghanaian Construction Industry

Abstract

Building Information Modelling (BIM) is a key computer aided technology that can facilitate construction productivity enhancements through the removal of numerous construction inefficiencies. This study investigates the use of BIM and its impact on construction project performance in Ghanaian architecture, engineering and construction industry. A cross-sectional survey design was adopted for the study. Self-administered questionnaires were used for data collection from architects, structural and civil engineers, project managers, quantity surveyors, contractors and general foremen in Greater Accra, Ashanti and Western Regions. Purposive sampling technique was used to elicit information from 300 participants. Data was analysed through the use of multiple response analysis, relative importance index (RII), principal component analysis and descriptively analysis. The results indicated that experts in the construction industry obviously agreed that the use of BIM has a great impact on construction project performance. Increase productivity, improve product quality and create customer value, help in removing barriers and constraints, reduce time of project design and shop drawings, improve communication effectiveness, provide accurate cost estimation and take off materials, reduce conflicts and number of claims, reduce defects in the construction phase, increase collaboration in project design were considered by the respondents as the most important factors for project performance improvement. It is recommended that experts and stakeholders should encourage the use of BIM technology in Ghanaian construction industry to improve construction project performance to meet customer satisfaction and also boost the infrastructural development.
