1. 1

   Initial enquiry

   Tell us about your project through the contact form, including any drawings or photographs you already have.

2. 2

   Review of information

   We review the available information — existing drawings, architectural proposals, site measurements and photographs — and confirm what is needed.

3. 3

   Quotation

   We agree the scope and fee with you before any design work begins, so you know exactly what will be provided.

4. 4

   Design and checking

   We carry out the agreed calculations, drawings or specifications, checked against the relevant standards.

5. 5

   Issue of deliverables

   The agreed drawings, calculations or design notes are issued to you electronically, ready for your builder or building control.

• Architectural drawings of the proposed work
• Any existing foundation or structural information
• Ground conditions information where available
• Site photographs and access details

• Foundation and groundworks layout drawings
• Setting-out dimensions and levels
• Coordination notes for the groundworks contractor

Foundation depths and widths depend on ground conditions, which can only be confirmed by excavation or investigation on site. Layouts are designed on the best available information, and building control will typically inspect the excavations before concrete is poured. Foundation engineering design itself is covered by our foundation design service.

Is this the same as foundation design?

The layout sets out where foundations go and how the work is set out on site. The engineering design — sizes, depths and reinforcement for the ground conditions — is our foundation design service, and the two are usually provided together.

Who checks the foundations before concrete is poured?

Building control normally inspects the excavations. Our drawings give them and the contractor the information they need.

Can you coordinate foundations with new drainage?

Yes — foundations and drains often compete for the same space, so we coordinate them on one set of drawings.
