Controlled fill placement and compaction after demolition, excavation or utility works — the strongest control happens before the trucks arrive, not after the last layer is buried.
Approved fill · layers · tested density
Placement, compaction and records — supply and testing kept explicit
The scope can include drawing/formation review, backfill-limit confirmation, controlled delivery and spreading, moisture conditioning, layer-by-layer compaction, controlled work beside sensitive interfaces, testing coordination, rework/retest handling and final survey/handover documentation.
Material supply, haulage, water, testing, survey, geotextile, ground improvement, permanent drainage, temporary works, authority fees and re-testing aren't assumed automatically — the quotation identifies which party owns each item.

Unsuitable ground, unresolved services or unapproved material shouldn't get buried beneath subsequent layers.

Hold points
If a loose layer is too thick for the material and equipment, the surface can appear firm while deeper material remains under-compacted. Lift thickness comes from the specification, approved method, manufacturer guidance or first-layer verification — never a generic website range.
Moisture conditioning
Plant selection
Sensitive interfaces
A density result proves the tested spot, not the whole layer — testing frequency and rework provisions factor directly into programme and cost.

Records & handover
An itemised, project-specific quotation reflects the confirmed material, void geometry, testing regime and handover documentation.
The method is selected after reviewing the structure, access, and risk — not chosen because it's the tool on the truck that day.
The method, sequence and controls are confirmed from the actual site condition before any machine or tool is mobilised.
Cutting, scanning, temporary support, lifting and waste handling coordinated under one plan, not fragmented between separate contractors.
Scope, exclusions, assumptions and handover condition are stated in the quotation — not hidden inside a single lump-sum line.
Controlled fill placement, moisture conditioning, layer-by-layer compaction and testing coordination — material supply, haulage and laboratory testing are stated separately unless expressly included.
Potentially, if segregated and shown suitable for the intended zone — same-site origin alone doesn't prove suitability.
Only for defined non-structural uses after controlled crushing and project acceptance — never automatically approved backfill or sub-base.
Set by the project specification and reference method — never a generic "95%" figure applied without the specified test method, frequency and acceptance party.
No. A density result proves the tested location, not automatically the entire lift — test frequency and coverage are set by the project procedure.
Only with stand-off, sequence and method confirmed by the issued design and responsible engineer — never assumed safe by default near sensitive structures.
The area is reworked and retested per the project non-conformance procedure — it isn't covered or built upon until it passes.
From the specification, approved method, manufacturer guidance or first-layer verification — specific to the material and plant, not a generic range.
