Abstract

The socio-economic environment in developing countries has often posed problems in completing projects on time. Additional costs are often incurred. The results of surveys carried out in construction companies in the Republic of Congo confirm the existence of shortcomings in the management of construction projects in developing countries. We propose a scheduling approach that can be used to plan projects for which effective financing is not assured before work begins, or for which management would be difficult with traditional scheduling methods (PERT and GANTT) because of financial difficulties. This is the PERT-ISSCD (Programme Evaluation and Review Technique - Improuved Sub-Structure Chaining Diagram), which is the combination of PERT (programme evaluation and review technique) and ISSCD (Improuved Sub-Structure Chaining Diagram). The application of PERT-ISSCD to an R+1 construction project with uncertain financing resulted in a completion time of 128 weeks and 152 days in the context of resource mobilisation based on the client's monthly savings.
