Substructure Design in Taunton SW — Engineering Everything Below Ground

Substructure design is needed for basement conversions, commercial substructures, retained excavations, and any project where the below-ground elements must be engineered as a whole. It suits clients who want one team to design and build the entire substructure.

Typical substructure design projects include domestic basement conversions, commercial basements and underground car parks, retained excavations, and foundation packages where the below-ground elements are complex.

Substructure design covers the structural engineering of everything below ground level: foundations, basement walls and slabs, retaining walls, and the waterproofing specification. Our in-house team designs the full substructure as a coordinated package, so the foundations, walls and waterproofing work together rather than being specified in isolation by different parties.

We assess the ground and the structural requirements, then design the full substructure — foundations, walls, slabs and waterproofing — as a coordinated package. The design is issued for building control approval, and the same team constructs it. We coordinate the whole sequence from design to DPC.

Substructure design cost is typically included within the overall package. The total cost depends on the complexity of the below-ground elements, the ground conditions, the size of the structure and the waterproofing requirements. We provide a fixed quote within 48 hours of the site visit.

Does substructure design include waterproofing?

Yes. Because we design the full substructure as a coordinated package, the waterproofing specification is included alongside the foundations, walls and slabs. This ensures the below-ground elements work together rather than being specified in isolation.
