Site uncertainties
With a YES, NO or UNSURE, please indicate if design and cost methods in South African construction Industry needs new Innovative ways of improving the performance of construction projects
With a YES, NO or UNSURE, please indicate if contracts that encourages more collaboration and eliminate problems between professionals and the contractor and subcontractors may improve the performance of public projects?
Please add any comment that you feel will contribute to the study of project's performance and thank you for your participation.
