certification auditor
A company which reviews a built object's qualifications to receive an official certification.
A certification auditor is a firm, company, or organization that reviews various features and qualities of a built object (usually after construction is finished), and determines its eligibility for any official certification.
The auditor must generally have independent standing, without close ties to companies responsible for development, construction, or design, so as to provide a trustworthy and objective assessment.
The review determines whether the built object meets the conditions for an official certification. A sustainable design consultant advises a project team on achieving environmental efficiency and certification, while the auditor assesses eligibility for the certification itself.
