  • Section is sloped or uneven and needs levelling before construction
  • Design levels on the plans do not match the natural ground
  • Too much cut material with nowhere on-site to put it
  • Not enough fill on-site and material needs to be brought in
  • Wet or soft ground that will not hold a level once shaped
  • Existing fill or spoil on the site of unknown quality

Define the work

Balance the cut, fill and material movements

01

Site walkover and level check against the design or consent drawings

02

Setting out cut and fill zones from survey pegs or plan references

03

Bulk cutting of high ground and placement of fill in low areas

04

Balancing cut-to-fill volumes on-site where the ground allows it

05

Cartage of surplus spoil off-site or import of fill where volumes don't balance

06

Compaction of placed fill in layers appropriate to the intended use

07

Rough grading to the levels shown on the plan

08

Erosion and sediment control measures while earthworks are underway

From site assessment to completion

From survey levels to a shaped site

  1. 01

    Plan review

    We check the engineered plans or consent conditions against the existing ground so cut and fill volumes are understood before machinery arrives.

  2. 02

    Setout

    Levels and boundaries are marked out on-site using survey pegs or reference points supplied by your surveyor or designer.

  3. 03

    Cutting and filling

    High points are cut back and the material moved to low points, balancing volumes where the site allows to reduce cartage.

  4. 04

    Compaction

    Fill is placed and compacted in layers, particularly under areas that will carry a building platform, driveway or hardstand.

  5. 05

    Trim and check

    Final levels are trimmed and checked against the plan before the site is handed over to the next trade.

Working conditions

Equipment and access for bulk earthworks & site cut-to-fill

Machine selection depends on the volume of material, how far it has to move around the site, and ground conditions on the day. Larger open sites suit different plant to tight urban sections, and we choose accordingly rather than running one setup for every job.

Plan around the work

Bulk earthworks are noisier and more visible than most other trades on a build, with machinery and truck movements over several days depending on volume. We plan truck timing around narrow streets and neighbouring properties, and sequence the work so surveyors and following trades aren't held up.

Get the detail right

Bulk Earthworks & Site Cut-to-Fill: decisions that matter

Getting cut and fill volumes wrong is expensive to fix once concrete or framing is in the ground, and poorly compacted fill can lead to settling under a slab or driveway years later. Reading a level correctly, compacting fill properly and managing where the water goes during the works all take equipment and judgement most property owners don't have on hand.

What does cut-to-fill actually mean?

It means moving material cut from the higher parts of a site to fill the lower parts, so the finished ground matches the design levels without bringing in or taking away more material than necessary.

Will the cut and fill balance perfectly on my site?

Not always. It depends on the natural slope and the design levels required. Where it doesn't balance we either cart surplus spoil away or bring in fill, and we'll flag this early once we've checked levels against the plan.

Do I need an engineer involved?

For most consented builds and subdivisions, yes — your designer or engineer sets the finished levels and any fill specifications. We work to those specifications rather than deciding levels ourselves.

How long does bulk earthworks take?

It depends on the site size, volume of material and access. A straightforward residential section is typically quicker than a multi-lot subdivision, and weather can affect the programme on clay-heavy Canterbury ground.

Can you work around a slope that's too steep for normal access?

We assess access and slope during the site walkover and choose machinery suited to the conditions. Very steep or restricted sites may need a different approach, which we'll discuss before quoting.
