NAS Certification for
Groundworks & Civils Contractors.
Groundworks and civil engineering contractors work in high-risk environments under CDM Regulations, environmental legislation, and strict health and safety obligations. NAS provides independently assessed business compliance certification — giving main contractors, house builders, and infrastructure clients verifiable evidence of your compliance standards.
