| Legal basis | Contract / Building Regulations |
| Purpose | Systematic element-by-element review confirming every specified requirement has been met, tested, documented, and evidenced |
| Scope | Materials, workmanship, testing, regulatory compliance, commissioning |
| Evidence-based | Each item must reference evidence — a checklist without evidence references is an assertion |
| Building Regs | Must confirm Part A (structure), Part B (fire), Part C, Part E (acoustic), Part F (ventilation), Part L (energy), Part M (access) |
1. Specification Compliance — Systematic Evidence of Contract Fulfilment
The Specification Compliance Checklist links each specification requirement to the evidence that it was met. It provides a complete, systematic record that every specified material, standard of workmanship, test, and regulatory requirement has been fulfilled and documented. A complete checklist provides the client with assurance that the works comply with the contract.
The checklist bridges the gap between the Inspection and Test Plan, which sets out what will be checked during construction, and the as-built package delivered at handover. It confirms that everything that should have been checked was checked, that evidence exists for each requirement, and that any nonconformances or deviations have been formally recorded and dispositioned through the NCR process.
Building Regulations compliance must be addressed within the checklist. Each relevant Approved Document — Part A (structure), Part B (fire safety), Part C (site preparation), Part E (acoustic), Part F (ventilation), Part L (conservation of fuel and power), and Part M (access) — must have its requirements mapped to evidence. For Higher-Risk Buildings under the Building Safety Act 2022, this evidence forms part of the mandatory golden thread.
The bridge between ITP and as-built
The specification checklist is the bridge between the ITP and the as-built package — it confirms everything that should have been checked was checked. Start populating it from day one, not the week before handover.
2. Specification Compliance Checklist — Content
The checklist must cover every section of the specification and link each requirement to specific, verifiable evidence. Each row represents a single specification requirement and the columns track the evidence chain from requirement through to formal sign-off.
Where a requirement has not been met and a concession has been granted through the NCR process, the checklist must record the NCR reference and the approved deviation. The completed checklist provides an honest and complete picture of the as-built condition.
The following table sets out the minimum columns required.
| Column | Description |
|---|---|
| Section | Specification section and clause reference (e.g. NBS Z21/310 or employer's requirements section) |
| Requirement | The specific requirement stated in the specification — material, workmanship standard, test, or performance criterion |
| Evidence required | The type of evidence needed to demonstrate compliance — test certificate, inspection record, commissioning result |
| Evidence reference | Reference to the specific evidence document — certificate number, report reference, O&M manual section |
| Compliance status | Current status — Compliant, Non-compliant (NCR ref), Concession (NCR ref), Pending, N/A |
| Building Regs Part | The applicable Building Regulations Approved Document — Part A, B, C, E, F, L, M, or multiple |
| Outstanding actions | Any outstanding actions required to achieve compliance or obtain evidence, with target dates |
| Sign-off | Name, role, date, and signature confirming compliance for this requirement |
3. Common Mistakes
Not starting until the week before handover
The specification compliance checklist should be populated progressively throughout construction, not compiled retrospectively in the final week. Evidence gathered in real time is reliable; evidence reconstructed from memory and incomplete records is not. Start the checklist at the same time as the ITP.
Not requiring evidence for each compliance claim
A checklist that states “compliant” without referencing specific evidence is an assertion, not a demonstration of compliance. Every compliance claim must be backed by a referenced document — test certificate, inspection record, commissioning result, or approved NCR concession.
Not including Building Regulations compliance
The checklist must cover regulatory requirements as well as contractual specification requirements. Each item should identify the applicable Building Regulations Approved Document and confirm that the relevant regulatory evidence (building control inspections, test certificates, EPC) has been obtained.
Not addressing NCRs and deviations
Where a specification requirement has not been met and a concession has been granted through the NCR process, this must be clearly recorded in the checklist with a cross-reference to the NCR. Ignoring nonconformances in the compliance checklist creates a misleading record of the as-built condition.
Not sharing the completed checklist with the client at handover
The completed specification compliance checklist is a key handover document that provides the client with a single summary of compliance status across all specification requirements. Failing to include it in the handover package misses the opportunity to demonstrate comprehensive quality management.
4. Frequently Asked Questions
Does the checklist replace the building control completion certificate?▾
No — the specification compliance checklist and the building control completion certificate serve different purposes. The completion certificate confirms regulatory compliance as assessed by the building control body. The checklist confirms contractual specification compliance as managed by the contractor. Both are required for a complete handover.
What is the relationship to the O&M manual?▾
The specification compliance checklist references evidence documents, many of which also form part of the O&M manual content — product data sheets, test certificates, commissioning records, warranties, and maintenance schedules. The checklist provides the index; the O&M manual provides the detail.
Who should sign off the checklist?▾
The QA manager and site manager should sign off the checklist as a minimum. For higher-risk projects, the designer and client representative should also review and sign off. The sign-off confirms that the evidence has been reviewed and the compliance status is accurate.
How does the Building Safety Act 2022 affect this?▾
For Higher-Risk Buildings (HRBs), the Building Safety Act 2022 requires a golden thread of building information to be created and maintained. Specification compliance evidence forms a critical part of this golden thread. The checklist provides the structured record linking requirements to evidence that the BSA demands.
