Detailed civil excavation

Specialist excavation around live services, trenching, site cuts and formation work for principal contractors in South East Queensland. The first cut has to be the right cut so the pipe and the concrete that follow actually fit the drawings.

Built for sites where tolerances matter

Anyone can drop a 20-tonne excavator in a paddock. You don’t need bulk earthmoving; you need surgical precision where millimetres dictate whether the pipe laser hits the invert and the formwork drops straight.

From live water and sewer tie-ins to complex trenching alongside rail corridors like the Beerburrum to Nambour (B2N) upgrade, we integrate into your program. We turn up induction-ready, manage our own SWMS, and hand over trenches that are shored, dewatered and clean enough for the next trade to move without arguing. Deception Bay based — Brisbane, Moreton Bay and the Sunshine Coast.

What we excavate

  • Underground utility trenching and shoring SEQ
  • Excavation around live services — Brisbane & Moreton Bay
  • Water, sewer and stormwater drainage trenches
  • Precise site cuts and pad preparation — Sunshine Coast
  • Benching and battering near live assets
  • Rail corridor civil work and easements
  • Pit, manhole and structure boxes
  • Bedding trim, backfill, compaction and restore

Rail possessions. The clock is the constraint.

A track possession is when the operator takes a section of railway out of service so civil work can happen without a train through the cut. On the Beerburrum to Nambour (B2N) footprint that window sits with the principal and Queensland Rail — not with the trade crew. We work inside it.

Possessions are usually nights and weekends, booked months ahead, and they end when the last possession minute ends. Last train in, first train out. The trench has to be shored, plated or backfilled so the road can be handed back. There is no “finish in the morning.” Adjacent roads and live services stay live. Plant swing, spoil and people stay inside the pegs.

  • Principal holds the occupancy — we hit the marks inside it
  • Night and weekend windows, not a paddock shift
  • Live adjacent track, drainage and utilities
  • Handover before the first train, not after

That is why we do not publish an hourly rate for rail corridor civil work. A possession that overruns is program drag. Send the drawings and the occupancy window.

How a typical day runs

Pre-start and permit to excavate. Confirm the mark-up. Open to the design invert, leave a clean batter or a boxed trench, and keep the spoil where the next trade can live with it. We work to the principal’s SWMS and plant — or tell you early if the ground wants a different machine. Insured, SWMS and site induction ready.

Rock, running sand and unidentified services change the price. That is why this page does not list an hourly figure. Send the drawings and the window; we will send a number that belongs to that job.
