The success of our projects depends on the quality of the subcontractors and suppliers we work with. We therefore assess firms that will join our approved list with transparent criteria and aim to build long-term partnerships.
Evaluation criteria
- References in similar work and completed contracts
- Occupational health and safety records, accident statistics and employee training certificates
- Financial capacity and documents showing no tax or social security debt
- Quality certificates (ISO 9001 preferred) and technical capacity
- Compliance with environmental legislation and waste management practices
Application process
Send your company, field of activity and references through the form on the Get a Proposal page. Our procurement and project teams assess your application within 10 working days; a site visit and quality audit are carried out for suitable firms. Approved firms are re-evaluated annually.
Payment and cooperation
Payment certificates are paid within 30 days on the schedule in the contract and with complete documents. Project-specific occupational safety training is given to all subcontractor employees before they enter the site.
