WHAT IS A CONSTRUCTION WORKS EXECUTION MANAGER?

The Construction Works Execution Manager—also known as the technical site manager or quantity surveyor—is the professional responsible for overseeing the proper execution of work on a construction site. Their main role is to ensure that the construction work is carried out in accordance with the approved project, complies with current regulations, and guarantees the quality and safety of the building.
