What is the role of an OPC mission?
As a project coordinator, the OPC mission has the role of optimizing the construction phase. It also allows to ensure the respect of the costs and deadlines approved upstream by the project owner. The presence of an OPC is justified when the project is established in separate lots but also in

What is the content of the OPC mission?
THE PRELIMINARY PHASES STUDIES AND PREPARATION OF THE BUILDING SITE
It is about an analysis of the contractual documents: the acts of engagement, the plans markets, the technical specifications, the CCAP. The OPC studies the difficulties and the specific requirements of the construction project and manages the administrative formalities required for the good preparation of the building site.
During the preparation phase the coordinator will analyze the elementary tasks by WBS hierarchical level and by lot. The OPC will organize the sequence of tasks and confirm a critical path. This phase also allows the establishment of a detailed schedule of studies, supplies, works and the chronological intervention of the works companies present on the site. The planning established by the OPC must integrate all the interfaces for the good coordination of the companies.
THE PHASE OF PILOTING AND COORDINATION OF THE BUILDING SITE
The OPC must harmonize the interventions of the various trades and service providers. He holds site meetings between the various participants, and ensures the distribution of the reports. The OPC must imperatively recalibrate the various phases of its planning with the respective progress of each task and to evaluate the analysis of the gaps between what was planned and the
THE PHASE OF RECEPTION OF THE WORKS
The completion of the works is initially the subject of visits prior to the preliminary operations of receptions called OPR with the organization of the tests. The reception of the works, formalized by the signature of a PV, generates the period of guarantee of perfect completion that the OPC must
also supervise with the trades.
Considering the certification of some works, the OPC must contribute in the planning of these objectives in the general planning of the operation.
The OPC has a strategic role allowing to control the prices of the operation. The non-observance of deadlines or defects sometimes have financial consequences that the project owner may want to charge him.
