Supervisors and Independent Certifier Services

Service Overview​

Supervisors and Independent Certifier Services

We provide NEC Supervisor (sometimes referred to as Supervisor) who is independent to the Project Manager and is responsible for monitoring, witness testing, compliance and ensuring that all works carried out are in accordance with the contract.

Our Supervisors will:

  • ensure that your contractors meet the highest quality standards set out in the Scope of Work.
  • issue instructions to search for any defects in the work.
  • take responsible for issuing Defects Certificates.
  • bring systematic thinking, proactive approach and effective teamworking to every project.

The Independent Certifier or Commissioner role is similar to the Clerk of Works role. It is a role principally used on JCT, PFI, or PPP projects to assure the principal stakeholders that the works are being completed according to the client’s standards, specification, and schedule as provided within the legal documents.
