How to inspect a GRP platform or walkway
A practical visual-inspection route for GRP walking surfaces, supports, fixings and edge protection—connecting observations to controlled records and competent technical review.
The central principle
Observe, record, report—and isolate the route if it appears unsafe.
GRP access systems are low maintenance, not inspection free. Regular visual checks protect the route, establish a useful condition history and identify changes that need competent review.
Begin with the project O&M manual, as-built information and site inspection plan. The inspection frequency, acceptance criteria and remedial action must remain project and asset specific.

Visual condition, traceable evidence and prompt escalation.
A GRP platform or walkway may be low maintenance, but it is not inspection free. Regular visual checks help keep the access route safe and preserve a useful record of its condition.
Begin with the project O and M manual, as-built drawing and site inspection plan. Confirm the system you are inspecting, its intended use, any known changes and whether access can be completed safely. If the route appears unsafe, isolate it and follow the site reporting procedure.
Start with the approach. Check that the route is clear, lighting is adequate and there is no standing water, ice, oil, debris or other contamination that could affect footing. Internal grating can normally be cleaned with a stiff broom. Water may be appropriate externally, but always follow the project guidance and environmental controls.
Inspect the walking surface. Look for cracks, broken bars, exposed fibres, heavy impact marks, distortion, unusual movement or worn anti-slip surfacing. Check that every panel remains correctly seated and supported, with no unexpected gaps or rocking edges.
Look at the fixings and joints without dismantling the system. Record anything missing, loose, damaged, corroded or disturbed. Do not improvise a repair or substitute a component without an approved technical review.
Check the supporting profiles, brackets and interfaces with the surrounding structure. Look for accidental damage, movement, unauthorised cutting or drilling, and any change to the equipment or loading around the route.
Inspect handrails, guardrails, gates, stairs and ladders included in the access system. Check continuity, stability, connections, edge protection and the condition of treads and landings. Any evidence of impact, movement or an altered arrangement should be reported.
Photograph and record the location, condition and date. Compare the finding with the previous inspection where possible. Vital O and M guidance requires regular visual inspection and immediate reporting of damage.
The inspector should not make a structural judgement beyond their competence. Isolate unsafe areas and obtain project-specific technical advice before repair or return to service.
