Purpose and Procedure for Drafting the Document
What Is a Hidden Works Acceptance Certificate?
A hidden works acceptance certificate is a formal document used to accept concealed construction works (such as reinforcement, waterproofing, or MEP installations) before they are covered by subsequent layers.
Why Use This Template?
This template provides a structured format for documenting the inspection and acceptance of hidden works, including project information, work details, inspection findings, and signatures from all parties.
Key Features
The certificate includes sections for project information, hidden works details, inspection findings, acceptance decision, and attachments. It supports multiple work items and photo evidence.
Construction Quality Assurance
Contractors and inspectors use this certificate to formally accept concealed works, ensuring that they meet design specifications before being covered.
Regulatory Compliance
Many building codes require formal acceptance of hidden works. This certificate provides documented evidence of compliance.
Contractual Handover
The certificate serves as a contractual record that the contractor has completed the works to the satisfaction of the inspector and project engineer.
Future Reference
The certificate, along with attached photos, provides a permanent record of the condition of concealed works for future maintenance or renovation.

Frequently Asked Questions about Photo Reports and Photo Tables
What types of works are considered hidden works?
Hidden works include reinforcement, waterproofing, MEP installations (ductwork, plumbing, electrical conduits), and any other works that will be concealed by subsequent construction layers.
Who signs the acceptance certificate?
Typically, the contractor, inspector, and project engineer sign the certificate. Additional parties may be required depending on the project.
Can I add multiple work items to one certificate?
Yes, the template allows you to add multiple hidden works items, each with its own description, location, type, and status.
Is photo evidence required?
Photo evidence is highly recommended and the template includes a dedicated photo collection field. Photos provide visual proof of the condition of works before covering.
What happens if the works are not accepted?
If the works are rejected or accepted with conditions, the certificate documents the reasons and required corrective actions. Works must be re-inspected after corrections.
