YOUR GROUNDWORKS ENQUIRY
Planning your groundworks job
Request groundworks for an agreed building or drainage proposal with site evidence, assets and access considered.
What to include in your enquiry
- Project and drawings
- Known services drains and surveys
- Access levels and disposal
What should the quote cover?
Specify investigation, excavation, protection, foundations/drainage design, spoil and reinstatement.
Can broad local geology set the foundation or soakaway design?
No. Actual site conditions, loading and water-route assessment are needed before specifying the work.
Local property and responsibility checks
The October 2023 flood investigation is historical context. Establish present levels, outlets, ground evidence and public assets for the actual plot.
- Project and drawings
- Known services drains and surveys
- Access levels and disposal

Groundworks begins with a site-specific plan
Quick answer
Request a quote for excavation, foundations or other defined groundwork, with the design, ground information and site access considered together.
Describe the project served by the work: extension foundations, a new drainage route or preparation for another structure. Excavation is a construction stage, not a substitute for a design. Soil, existing buildings, trees, utilities and access can affect the proposal. Ask what information is needed before a price is confirmed. A standard trench depth or area rate is not proof of suitability. Keep the intended result and design responsibilities clear before machines arrive.
Ground conditions and foundation design
The foundation arrangement needs assessment for the actual building and ground. Existing structures and nearby features can change requirements. Ask who provides investigation and design, what assumptions remain and which findings require review. Do not dig inspection holes yourself near structures or services to prepare a quotation. HSE warns that excavations can undermine adjacent structures. Appropriate support and precautions need planning. The builder should work to the assessed design and relevant inspection requirements rather than a generic local rule.

Buried services and safe excavation
HSE’s underground-services guidance sets out planning, identifying services and safe excavation. Records help but do not certify every exact route or depth. Ask how the contractor obtains and checks relevant information before work. Unknown or conflicting findings need resolution through the appropriate operator and professionals. Keep people away from the active work area. This site does not locate utilities or give a household digging method; a completed enquiry does not authorise excavation around an unidentified asset.
Find the asset and an assessed drainage outlet
Locate actual buried assets and establish an assessed drainage outlet before excavation. Anglian Water’s public-asset route and property-specific ground evidence are separate requirements; a historic flood or geology overview is not a design test.

Plan delivery access and adjoining protection
Describe the final approach, gate width, parking, unloading and adjoining protection needs. The county transport plan maps Stowmarket’s road context but does not guarantee plant access or a delivery time for the site.

Groundworks costs and discoveries
Ask before commissioning
Compare setting out, excavation assumptions, disposal, specified construction, testing and reinstatement. Ask who confirms utilities and discharge permissions and how unexpected ground conditions will be agreed before extra work.
- What design and site information governs the work?
- How are services, safety and inspection stages handled?
- Who approves discoveries, disposal and reinstatement costs?
Inspection records and completion
Plan the relevant inspections before concealed work is covered and retain the as-built information, findings and approvals where required. Ask which stage is being handed over and what remains for later trades. Keep maintenance access and installed drainage details available. For an enquiry, send postcode, project purpose, current design stage and known site constraints. We review suitable local requests; sending details does not book machines, grant permission or guarantee conditions can be determined without assessment.
