For contractors, certification is often a condition of tender. Public clients and principal contractors use ISO 9001, ISO 14001 and ISO 45001 to pre-qualify bidders, and anti-bribery controls are increasingly requested on public projects.
Industry Challenges
- Tender and pre-qualification requirements
- High-risk site activities and temporary sites
- Subcontractor and supplier control
- Environmental impacts: dust, noise, waste, runoff
- Bribery risk on public contracts
