Three things to know
- Distinguish the intended use and loading of each area.
- Connect target levels with entrances and surroundings.
- Earthworks do not automatically include the finished surface.

Match the base to the intended use
Start with the intended use and surface. Provide the base specification for that particular area rather than borrowing a universal thickness from another project. Split the quote into removal of existing layers, excavation, material, base preparation and the finished surface. Each stage should have a clear completion point.
Establish connecting levels before excavation
Show the door threshold, gate, adjacent pavement, ground and any other points the new area must meet. Include the future surface level and the specified layers. Today’s garden level may not be the target.
Arrange setting out and handover by the responsible person. Changes to the final material or level need agreement before proceeding, as they can affect excavation and material deliveries.
Separate the three stages and their contractors
Distinguish excavation and removal of existing layers, construction of the specified base and the final surface. Define the result of each stage. If different firms are involved, agree their requirements before the first starts.
The quotation should show whether you are ordering excavation alone or also supply and construction of the base layers. Identify who supplies materials and who accepts the prepared area. Use the actual design for the build-up and required checks.

| Stage | Information before work | Handover agreement |
|---|---|---|
| Earthworks | Scope, levels, existing layers and services | Required geometry and condition |
| Base | Layer design and material requirements | Completion and specified checks |
| Surface | Confirmed material and connecting details | Edges, transitions and the agreed result |
| Transport | What leaves, arrives and where it unloads | Quantity, handling and timing |
Include water, services and surrounding structures
Identify downpipes, chambers, known wet areas and services beneath the area. Water management must be part of the design in relation to the house and surroundings. Simply raising the surface without establishing the consequences is not a complete brief.
Show edges, roots and nearby structures. If something must remain, the design needs to account for it. Photographs alone cannot establish the technical suitability of every detail.
Keep deliveries clear of earlier work
Plan removal and incoming materials around loading and unloading space. If a vehicle cannot reach the work, define the additional handling. Delivery does not automatically include spreading or constructing the layers.
Before ordering, confirm that unloading space is available and establish how material reaches the area. If removal and deliveries share a route, they need one timing plan. Using several contractors does not resolve this by itself.
Compare quotations item by item
Before comparing totals, check removal of existing layers, excavation, loading and disposal. Then compare material supply, on-site handling, base construction and the finished surface. An item missing from one quotation may mean a different scope.
You can write: “I am preparing a [terrace / path / driveway] of [dimensions] for [use]. The final surface will be [material]. The layer design and levels are [attached / not yet available]. I need [excavation, removal, base, surfacing]. The next stage is by [contractor].” Attach current-site and access photographs.
Frequently asked questions
Can a path and driveway use the same excavation?
There is no universal answer. The design depends on use, ground conditions and the specified construction.
Does base preparation include the finished surface?
Only if agreed. Separate earthworks, layers and surfacing, and identify the contractors.
How do I enquire without a layer design?
Send your intention and available information and identify the missing design. Complete it before the particular construction is carried out.
Who confirms readiness for surfacing?
Agree the responsible person and acceptance conditions using the design and the next contractor’s requirements.
Request the scope you actually want completed
Send dimensions, use, intended surface and any available design. Say whether you need excavation only, a prepared base or subsequent construction as well.
