Subcontracting: Document control across the entire contractor chain

When a contractor passes part of the work on to other companies through subcontracting, each tier adds workers, equipment, documents and risk. The challenge is to ensure that everyone meets the same requirements and to know, at any given moment, who is working on your premises.

In brief

How to control subcontracting

Construction, energy and industry often work with chains of several tiers. These rules keep them under control.

01

The full chain on record

Each company stays linked to the company that hired it directly, at every tier of the chain.

02

Requirements at every tier

Document requirements apply to everyone, according to activity and risk. Each company is responsible for its own workers and subcontractors.

03

Contractor approval before mobilisation

No company enters the site without validated documentation, even at the third tier of subcontracting.

04

Traceable decisions

The platform records who submitted, validated and approved each document.
