Wind Load (EPA) & Foundation Center

High mast poles are structural systems. This page standardizes what to prepare and what to request (calculations + drawings + foundation checklist).

Run the Structure Bundle

Follow the structure-ready sequence.

Required inputs (copy/paste)

Project location:
Pole height (m):
Luminaire quantity per mast:
Luminaire projected area (if known) / model:
Wind speed / wind zone (or local code reference):
Terrain / exposure category (if specified):
Topography notes (coastal, open plain, hillside):
Lowering device required? (yes/no):

Deliverables to request

  • Structural calculation package (local standard compliance stated).
  • General arrangement drawings: pole, base plate, anchor bolts, lowering device (if any).
  • Foundation checklist: foundation type, bolt cage details, rebar schedule (or required inputs).
  • Material & protection: steel grade, galvanization thickness, coating (if required), fasteners.
  • Quality records: weld inspection, dimensional checks, traceability.

RFQ clauses (copy/paste)

  • Supplier must provide structural calculations and confirm compliance with the applicable local standard/code.
  • Supplier must provide drawings for pole, base plate, anchor bolts, and lowering device (if required).
  • Supplier must provide a foundation deliverables checklist and state required site inputs (soil, constraints).
  • All assumptions must be stated (wind zone, exposure, luminaire area, safety factors).

Acceptance & handover records

  • As-built drawings / final drawings set
  • Material certificates + galvanization/coating records
  • Inspection records (welds, dimensions, fasteners)
  • Lowering device commissioning and maintenance instructions (if used)
