The steps for a project in Darlington
Brief
We agree the use, occupancy, hours and budget. For sites in Darlington we confirm access and parking beforehand.
Survey
We measure the space and record fabric, glazing and services.
Calculate and design
Loads are calculated and a system designed.
Specify
You receive drawings and a specification.
Local points to consider
Coordination
Ceiling, lighting, sprinkler and electrical layouts are coordinated early.
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.
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 Darlington 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.
