Professional PFI Services & Technical Governance.
From Notice to COC.
We provide the “Technical Bridge” Building Managers need to navigate the PFI lifecycle. From Direct PFI Inspections for medium assets to Independent Audit & Coordination for large-scale commercial projects—we ensure TR-78 compliance while protecting your Sinking Fund.
Direct PFI Service
Technical Coordination & Audit
From BCA Notice to Certificate of Compliance (COC).
Stage 1: Inspection & Analysis (Submission)
We handle the TR-78 digital scan and RFI-led data verification. For large assets, we disqualify “Hobbyist” quotes and audit hardware specs before you sign a contract.
Stage 2: Repair & Cost Control (The BOQ)
We convert defect data into a measurable Bill of Quantities (BOQ). We act as the “Eyes on Site” for the PE’s Certificate of Supervision (COS), ensuring you only pay for necessary repairs.
Stage 3: Final Verification (COC)
We conduct final “Before vs. After” verification scans to provide the legal proof required for the PE to sign the final Certificate of Compliance.
Bridging the Gap for PEs and RFIs.
RFI Data Auditing: We assist the PE by managing the Registered Facade Inspector (RFI) workflow—filtering thousands of drone images into actionable defect logs.
Construction-Led Supervision: Our background in the built environment ensures that in the Repair Phase, your contractors are held to the exact specifications required for a smooth COC sign-off.
Moving Beyond the Drone Data Report.
Most drone firms stop at the data report. Greener Air specializes in the Built-Environment FM field. We stay involved during the rectification works to ensure materials and methods match the PE’s requirements. This independent coordination reduces “Repair Bill Shock.
