Summary

Who orchestrates a construction project's success, transforming architectural dreams into concrete reality? The Direction de l’Exécution des Travaux (DET). Working behind the scenes, the DET harmonizes design and reality, acting as the guardian of best practices between the client, project manager, and stakeholders. Discover the essential, influential role the DET plays in turning a concept into a tangible structure.

Step 1: Completion of the work

The Construction Project Management (CPM) department is an internal organization within each construction project, headed by the Construction Manager or, in some cases, the Fire Safety System (FSS) coordinator. The CPM ensures the transformation of architectural visions into reality . Its role extends beyond mere on-site activities. It embodies the guarantee of faithful and high-quality execution of construction projects.

Established by the MOP law of 1985 and reinforced by the decree of November 29, 1993 , the DET is a mandatory device for all construction projects.

Who is the MOE and what are its roles?

The Project Manager (MOE) is at the head of the DET , and coordinates and supervises all phases of the project, from genesis to delivery.The roles of the MOE are as follows:

  1. Monitoring of works : the project manager ensures constant supervision to guarantee the progress and quality of the works, adapting the project to the realities on the ground if necessary.

  2. Compliance check: it validates the suitability of the work with the standards and urban planning authorizations, an essential step for the final validation and associated guarantees.

  3. Financial management : he develops a provisional budget and rigorously monitors expenses to control costs and anticipate additional financing needs.

Distinction between the Project Owner (MOA) and the Project Manager (MOE)

The Project Owner (MOA) is the client of the project , the one who finances and defines the needs of the construction project, while the Project Manager (MOE) is responsible for the design and supervision of the execution of the work , ensuring that the project meets the specifications of the MOA and the standards in force.

The importance of collaboration in the mission of the Works Execution Directorate (DET)

The Works Execution Department (DET) is not limited to rigorous monitoring and management of construction phases. It also embodies a dynamic collaborative space between key project stakeholders, a true driving force for delivering a project that meets expectations, both in terms of quality and deadlines.

Verification and documentation process

The accuracy and fidelity of the execution in relation to the initial plans are ensured by a meticulous verification process, which constitutes the core of the DET. This verification is based on a thorough comparison of contractual documents, such as plans and specifications, with the actual work carried out on site .In parallel, the documentation produced under the direction of the Project Manager, particularly work orders and meeting minutes, accurately captures the project's evolution and adjustments. Regular site meetings provide a favorable environment for exchanging ideas and adapting strategically to unforeseen events, thus strengthening the project's documentation base.

Collaborative dynamics and dispute management

The effectiveness of the Project Management Team (PMT) relies on close and proactive collaboration between the project manager, the client, and the contracted companies . This interaction allows for the alignment of visions, the unification of efforts, and the collective overcoming of challenges, contributing to the smooth progress and success of the project. In the event of disagreements or disputes, the project manager's role as mediator becomes crucial. Their ability to offer informed advice and initiate constructive solutions enables the project to navigate turbulence, ensuring continuity while maintaining quality and adherence to deadlines.To facilitate this collaborative dynamic and the effective management of disputes, it is essential to have the right tools for optimal document organization and communication. These tools provide a centralized platform for information sharing, ensuring that all stakeholders remain informed and engaged throughout the project.

Technology at the heart of collaboration

Collaboration within the framework of the Works Execution Management (DET) finds a formidable ally in digital tools for construction. A solution like Trimble Field View improves site monitoring thanks to its real-time data collection capability, while Viewpoint For Projects centralizes documents and facilitates the history of all building-related documentation.This type of software enhances transparency, accelerates problem-solving, and optimizes decision-making, playing a key role in improving the quality of work and meeting deadlines. Its integration into construction processes represents a step forward toward more connected and efficient working methods.As you will have gathered, the Construction Execution Department (DET) is essential to the smooth running and success of construction projects. It ensures faithful execution of the plans, rigorous document management, and effective mediation in disputes, while fostering close collaboration among all stakeholders. The integration of advanced technologies strengthens this mission by offering solutions for seamless communication and optimal project management. Thus, the DET plays a vital role in transforming construction projects into concrete structures.
