Belgian site-safety cascade: who checks each subcontractor in the chain?

A subcontractor list is not only a commercial overview. On a Belgian temporary or mobile construction site, safety duties cascade through the execution chain. The practical challenge is to identify who contracted whom, which measures apply and who must intervene when a lower-tier company does not comply.

Draw the contractual chain

Start with the project supervisor responsible for execution, then list each contractor and its direct subcontractors. Record legal entities rather than informal crew names. Add the contract, scope, site dates and responsible contact for every link.

The Belgian FPS Employment guidance explains that the project supervisor must comply with safety measures and ensure compliance by contractors, subcontractors and workers. A contractor must comply and ensure compliance by its direct subcontractor and the chain below it. A subcontractor has duties toward its own direct subcontractor and workers.

Separate checks from presence registration

CheckInAtWork or another attendance record can show who registered. It does not prove that inductions, risk controls, equipment, permits or contractual safety clauses are complete. Keep presence, qualification and safety evidence as separate facts with their own owners.

Define the escalation path

For each missing item, name the direct contracting party that must act, the site owner who can pause access and the evidence needed to clear the exception. Do not rely on a message forwarded through several tiers without a responsible sender and deadline.

Keep software within the legal boundary

Construction software can display the chain, expiries, tasks and evidence. It cannot decide legal responsibility by itself or replace the safety coordinator and competent people. Configure permissions so sensitive worker documents are only visible to those who need them.

Review whenever the chain changes

Repeat the check before a new lower-tier subcontractor starts, when scope changes or when a company brings additional personnel. Archive the decision with the project, but consult current official guidance for the applicable site.

Run a pre-start chain review

Two working days before a lower-tier company starts, review the chain with the site manager. Confirm the direct contractor, scope, named supervisor, required evidence and open exceptions. Ask who can deny or pause access if an item remains unresolved. Record the decision rather than marking the whole company “compliant” indefinitely. A later crew, task or piece of equipment may need a new check. If a company is replaced, close its open access and evidence tasks without deleting the historical record. This makes the chain useful during an incident investigation and avoids treating a stale spreadsheet as a live safety decision.
