Abstract: A major Canadian utility company has recently added the dimension of time (4D) to its scheduling on four new facilities and rehabilitation hydroelectric projects using Delmia®. As-planned project schedule evolution is viewed on a Gantt chart, while progress is shown on the project's 3D mock-up. Each mock-up piece is matched to distinct schedule activities and according to project complexity and user type, a summary or detailed level is selected for simulation. With this new technology, now schedulers, estimators, engineers and managers can enhance internal standards by building quick-thinking schedules, reviewing project scenarios, providing insight on constructability, methods and optimizations, preventing safety hazards, choosing better materials and predicting costs in a more accurate fashion. 4D scheduling facilitates earlier knowledge about interfaces, existing conditions, access and material handling, reduces requests for information, accelerates change process and enables easier communications between stakeholders from pre-feasibility till end of construction phase.
