Site supervision: practical definition

The query what is site supervision usually appears right before construction starts. It is the technical control of execution to ensure what is built matches the approved project.

It is not an administrative formality: it is an ongoing role of review, coordination, and decision-making during works.

What tasks it includes day to day

It includes site visits, issue resolution, verification of materials and construction solutions, and coordination with contractors and suppliers.

It also helps anticipate cost and timeline deviations before they become major problems.

Why it directly affects final quality

Without active technical supervision, decisions become fragmented and error risk grows. Late correction is usually more expensive.

At BAU, we treat site supervision as an essential project stage to protect architectural quality and financial control.
