Mounting choice affects everything: structure, aiming, spill control, and long-term maintenance cost. This guide gives a fair comparison framework and the evidence to request so the project remains buildable and maintainable.
- Point clé #1 : Roof-mount can be elegant but can hide structural and access risks.
- Point clé #2 :Pole-mount often wins on aiming flexibility and serviceability.
- Point clé #3 :Define evidence early to avoid redesigns and handover disputes.
Table des matières
Dans les cas suivants
Use this guide when selecting mounting strategy for new stadiums or retrofits with existing grandstand/roof structures.
Typical scenarios
- New builds: you can design structure and routes for the lighting from day one.
- Retrofits: roof capacity and cable paths may be constrained.
- Neighbor-sensitive sites: mounting geometry affects glare/spill angles.
- High access cost: maintenance strategy can dominate TCO.
Exigences clés / indicateurs clés
Use these metrics to compare mounting options in a buildable and maintainable way.
| Factor | Quelles sont les conséquences ? | Pourquoi est-ce important ? | What to verify |
|---|---|---|---|
| Structural capacity | Safety and approvals. | Roof structures require verification. | Structural confirmation / check request. |
| Aiming geometry | Glare/spill risk. | Bad geometry forces high tilt. | Max tilt policy + aiming table. |
| Cable routing | Buildability. | Hidden routes create delays. | As-built route records and diagrams. |
| Maintenance access | Lifecycle cost. | Access is the real cost driver. | Access plan + SOP + spare strategy. |
| Commissioning evidence | Acceptance and disputes. | Fixed poles limit options. | Aiming table + photos + deviation log. |
Definitions
Roof-mounted lighting attaches to roof/truss structures; pole-mounted lighting uses standalone poles around the field. The best choice depends on structure, aiming geometry, and lifecycle maintenance access.
Practical targets
Typical guidance (always follow tender text):
- Roof-mount must have confirmed structural capacity and defined cable pathways
- Pole-mount must validate spill/glare and aiming within defined tilt limits.
- Both need an access/maintenance plan and an auditable sign-off pack.
Déroulement étape par étape
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
- Roof structure drawings (if roof-mount) or pole constraints (if pole-mount).
- Site boundaries and spill/glare constraints.
- Access method and safety rules.
Design decisions
- Select mounting option based on buildability and maintenance, not only aesthetics.
- Define aiming policy and verify through calculation.
- Define evidence pack requirements at handover.
Verification & sign-off
- Structural confirmation (roof-mount), aiming table, as-built routes, and SOP.
Erreurs courantes
- No structural confirmation for roof-mounted projects
- No access plan (maintenance becomes a crisis later).
- Ignoring glare angles created by roof geometry.
- No as-built route documentation.

FAQ
Is roof-mounted lighting always better than pole-mounted?
Not always. Roof-mount can reduce pole count and improve aesthetics, but it creates structural, access, and glare-angle challenges depending on geometry.
When does pole-mounted win?
When you need flexible aiming, easier maintenance access, or when roof structure cannot support loads or routes.
What is the biggest risk in roof-mounted projects?
Underestimating structural load/pathways and access for maintenance, leading to delays and long-term service challenges.
How do I compare options fairly?
Compare on constraints: structural capacity, aiming limits, spill/glare behavior, installation pathways, and maintenance cost over time.
What should the sign-off evidence include?
Structural confirmation, aiming table, as-built routes, and maintenance SOP/access method.
