In the wake of the implementation of the Building Safety Act 2022 (BSA), the days of the “box-ticking” handover are over. For Principal Contractors and M&E Contractors, “finished” no longer means just completing the physical build, it means proving a safe, occupiable building through a validated, digital Golden Thread of information.

If you are working on Higher-Risk Buildings (HRBs), those at least 18 metres tall or 7 storeys and AND containing at least 2 residential units, the documentation you provide is now a statutory requirement for legal occupation. Without the right evidence at Gateway 3, the Building Safety Regulator (BSR) will not issue a Completion Certificate, and the building cannot open.

The New Reality: From Compliance to Demonstration

The BSA shifts the industry from “minimum compliance” to demonstrable safety. This transition is governed by the BSR, who now holds the power to stop projects in their tracks if the documentation doesn’t measure up.

To navigate this, industry leaders are focusing on three core pillars:

1. The Golden Thread: A continuous, digital record of a building’s design, construction, and management.
2. Accountable Persons: Clearly defined roles (Principal Designer, Principal Contractor, and Principal Accountable Person) who are legally liable for safety.
3. The Gateway Process: Three mandatory “hard stops” where safety must be evidenced to move forward.

What Needs to be Evidenced at Completion?

As projects reach Gateway 3 (Completion), the technical burden falls heavily on those providing construction documentation as a “single source of truth” that proves the as-built reality matches the approved design.

1. The Digitised Golden Thread: The Act mandates that information be stored and managed digitally. This isn’t just about PDFs on a USB stick; it’s about structured, searchable, and interoperable data.

• Building Handover Manual and O&M Manuals: Must be digitally indexed and asset-based.
• Health and Safety File (CDM 2015): a primary source of information for the Golden Thread
• CIBSE TM31 Log Books: Essential for proving that life-safety systems (smoke extract, sprinklers, alarms) are commissioned and operational.

2. The Regulation 38 File (Fire Safety Information):Perhaps the most scrutinised document at handover. You must provide comprehensive fire information, including:

• As-Built Evidence: Precise records of fire-stopping, cavity barriers, and structural protection.
• Photographic Proof: The BSR increasingly expects GPS-tagged photographic evidence of “hidden” safety elements before they are covered up.

3. Competence & Declarations: At completion, the Client, Principal Designer, and Principal Contractor must sign a Completion Declaration. This confirms that the building complies with all regulations. To back this up, contractors must evidence the competence of their entire supply chain, ensuring every sub-contractor providing safety-critical info is qualified to do so.

How Structured Documentation Supports Compliance

A “dump” of manufacturer data sheets is no longer acceptable. The BSR requires structured documentation which actively proves safety, this ensures:

• Clarity: Safety-critical data is flagged and easy to find eliminating the “information Gap”
• Consistency: Information is aligned across mechanical, electrical, and structural disciplines.
• Longevity: The Principal Accountable Person (PAP) receives a package that feeds directly into the Building Safety Case Report, allowing them to manage risks throughout the building’s lifecycle.

Mitigating Risk with Dewick & Associates

For many contractors, the administrative and legal weight of the BSA represents a significant project risk. Dewick & Associates acts as your technical partner to bridge the gap between standard construction files and BSA 2022 compliance.  Our engineering-led approach ensures that we understand the M&E systems we are documenting, allowing us to identify gaps in the Golden Thread before the BSR does. We ensure that your documentation isn’t just a pile of paper, but a high-performance asset that secures your Completion Certificate and protects your professional liability.

How we support your handover:

• Technical Authoring: We don’t just collect folders; we write the content. Our engineering background allows us to produce authored narratives and verified data that the BSR demands.
• Digital Management: All Building Handover Manuals, O&M Manuals, H&S Files and Reg 38 Files are hyperlinked, searchable, and audit-ready.
• As-Built Verification: We can coordinate the collection of photographic evidence for fire-stopping, integrating it directly into your compliance dossiers.

Don’t let documentation be the bottleneck that resets your 8-week BSR approval clock. Ensure your handover is an asset, not a liability.

Note on Regional Application: While the BSA 2022 applies in full to England, Wales operates under its own version with a broader scope (HRBs include any building 18m+ with at least 1 residential unit). Scotland and Northern Ireland maintain their own distinct building regulations (Building Act 2003 and 2012 respectively).
