Unknown ground
Made ground, clay movement, trees, groundwater and previous structures can change the safe excavation or foundation strategy.

The direct answer
Groundworks & Foundations: what matters most?
Good groundworks convert drawings and site conditions into a stable, buildable platform. That means controlling excavation, levels, water, bearing ground, access and spoil—not simply digging to a nominal depth.
Our first survey focuses on the variables that change method, risk and price. The written scope then states the included work, important assumptions and the information or approvals still required.
Real A Jones project photographyTypical scope
What we can include
- Site set-out and reduced-level excavation
- Strip, trench and engineered foundations
- Oversites, sub-bases and concrete preparation
- Drainage, service ducts and attenuation
- Spoil management and site clearance
- Ground beams, slabs and retaining structures
Every site is different. The quotation—not a generic web list—defines the final package.
Devil in the detail
Four issues worth resolving before work starts.
Good planning makes risk visible while there is still time to change the method.
Levels & water
Finished levels, falls and drainage routes must work together before concrete or paving fixes them in place.
Access & sequencing
Machine size, haul routes, temporary support and spoil removal affect programme and cost as much as the excavation volume.
Inspection points
Building Control and design-team checks need to be planned into the sequence, with excavations kept safe and ready to inspect.
How the work progresses
A six-stage route from question to handover.
The exact construction changes; the discipline of resolving information before burying it does not.

Plan with better information
Use a calculator, then let the site visit replace assumptions.
Our tools organise quantities and project details without pretending to be a quotation. Results make the first survey more useful.
Frequently asked
Groundworks & Foundations questions
Clear answers before commitment make the survey, quotation and build easier to compare.
What do groundworks include?
Depending on the project, groundworks can include site clearance, excavation, foundations, drainage, service ducts, sub-bases, concrete slabs, retaining walls and preparation for the main build or finished surface.
How deep do foundations need to be?
There is no safe universal depth. Soil, trees, nearby structures, loading, drainage and the engineer or Building Control requirements all matter. We price against the actual design and site evidence.
Can you handle excavation and spoil removal?
Yes. We plan machine access, segregation, loading, grab or haulage requirements and lawful disposal as part of the work rather than leaving spoil as an afterthought.
Do you work from structural drawings?
Yes. We coordinate the construction sequence with structural and drainage information and flag unclear details before they become buried problems.
