Abstract
This research looks at the sustainable construction project execution in Ghana and focuses on the influence of factors contributing to increase in projects execution cost, factors affecting project cost control, causes of materials waste generation on sites, materials waste generation effect on projects cost, and material cost reduction strategies in the building industry. The study employed stratified random sampling, simple random sampling and purposive sampling techniques in selecting the respondents. The study found that the influential factors that cause increase in project cost are fluctuation in price of raw materials (3.13) and unforeseen site conditions (3.03). The results also showed that unsuitable construction equipment and methods (2.96), shortage of skilled labour (2.80), and poor contract management (2.76) are the challenges in controlling a project cost increased. Furthermore, the lack of regular clerk supervision (33.3%), theft of materials (30.0%) and inability of site supervisor to read and interpret working drawings (20.0%) are the causal factors of waste generation. The findings also indicate that cost waste prevention activities (2.80), conducting periodic brainstorming session on how to reduce waste (2.73) and post jobsite waste reduction plan in central locations (2.70) are the waste reduction strategies on construction site. Based on the findings of the study, it is recommended that project managers should adopt acceptable management tools and measures, apply project waste reduction strategies and project cost control measures to enhance on project efficiency.
