Most handover disputes are evidence disputes. This guide defines a practical sign-off pack that links acceptance criteria → commissioning records → as-built documentation—so acceptance becomes predictable.
- Key takeaway #1: If it isn’t documented, it didn’t happen—sign-off depends on evidence.
- Key takeaway #2:Aiming tables and commissioning logs are the core of acceptance, not optional extras.
- Key takeaway #3:As-built BOM/routes + photos reduce future downtime and maintenance cost.

When this applies
Use this guide when you want predictable acceptance for stadium/sports lighting—especially for retrofits, multi-scene controls, or projects with strict constraints.
Typical scenarios
- Owner sign-off: needs clear evidence and repeatable method.
- Retrofits: as-built documentation prevents future uncertainty.
- Multi-scene controls: commissioning records are essential.
- Auditable projects: public-sector or consultant-led approvals.
Key requirements / metrics
These pack elements turn “handover” into a controlled process.
| Pack item | What it affects | Why it matters | Minimum evidence |
|---|---|---|---|
| Acceptance method | How pass/fail is determined. | Prevents disputes. | Grid + scenes + rules. |
| Calculation evidence | Design intent. | Aligns tender to design. | Report + assumptions. |
| IES/LDT register | Traceability of optics | Prevents wrong files/versions | Register + versions. |
| Aiming table | As-built aiming. | Controls glare/spill | Tilt/azimuth + photos |
| Commissioning logs | On-site verification. | Records deviations and fixes. | Scene tests + approvals |
Definitions
A sign-off pack is the evidence bundle that proves compliance and makes future operation maintainable. It links what was required → what was designed → what was installed → what was verified.
Typical target ranges
Minimum pack target: everything required for acceptance and maintenance.
- Include as-built BOM/version list and route documentation for long-term maintainability.
- Include photos at key interfaces (aiming, glands, JBs) to reduce future troubleshooting time
Step-by-step workflow
Workflow: define tier → map constraints → test 4/6/8 pole options in calculation → choose option with best risk profile → lock aiming limits and sign-off deliverables.
Inputs to collect
- Tender acceptance method and targets
- Site boundaries and spill/glare constraints.
- Access method and safety rules.
Design decisions
- Define the pack as a tender requirement
- Standardize templates used by installers and commissioners.
- Define who signs off each part and when.
Verification & sign-off
- Complete checklist + signed logs + as-built documentation delivered.
Common mistakes
- Collecting evidence after the fact (missing photos/logs).
- No IES/LDT version control.
- Aiming adjusted on site without records.
- No as-built BOM/routes for future maintenance

자주 묻는 질문
What is a stadium lighting sign-off pack?
A structured set of documents and records that prove the installed system meets the tender requirements and can be operated and maintained.
Why do projects fail at handover?
Because evidence is missing: measurement method, aiming tables, commissioning records, and as-built documentation.
What should be in the minimum sign-off pack?
Acceptance criteria, calculation report, IES/LDT file register, aiming table, commissioning logs, as-built BOM/routes, and maintenance/spares plan.
Should I include photos?
Yes. Photos make installation and aiming evidence defensible and speed up future troubleshooting.
How do I make sign-off predictable?
Define the pack in the tender and use checklists and templates during commissioning.
