4D Scheduling Using Delmia~? and Microsoft Project~? on Hydroelectric Construction Projects

摘要

A major Canadian utility company has recently added the dimension of time (4D) to itsscheduling on four new facilities and rehabilitation hydroelectric projects using Delmia?. Asplannedproject schedule evolution is viewed on a Gantt chart, while progress is shown on theproject's 3D mock-up. Each mock-up piece is matched to distinct schedule activities and accordingto project complexity and user type, a summary or detailed level is selected for simulation. Withthis new technology, now schedulers, estimators, engineers and managers can enhance internalstandards by building quick-thinking schedules, reviewing project scenarios, providing insight onconstructability, methods and optimizations, preventing safety hazards, choosing better materialsand predicting costs in a more accurate fashion. 4D scheduling facilitates earlier knowledge aboutinterfaces, existing conditions, access and material handling, reduces requests for information,accelerates change process and enables easier communications between stakeholders from prefeasibilitytill end of construction phase.
