Things to check in Belfast
Noise
Fans and grilles are selected and attenuated to keep noise down.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Access and parking
Town-centre jobs in Belfast often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
