Local points to consider
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Access and parking
Town-centre jobs in Gravesend 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.
Coordination
Ceiling, lighting, sprinkler and electrical layouts are coordinated early.
Working hours
Most Gravesend businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
