Our services

01

Basement Excavation & Bulk Earthworks

CBEM carries out basement excavation and bulk earthworks for building sites and subdivisions, from bulk cut and fill to detailed excavation and final trimming.

Scope of works

  • Site preparation and bulk excavation
  • Cut and fill, including placement of engineered fill
  • Detailed excavation to formation levels
  • Material handling, removal and site trimming

Construction

Before excavation starts, we review ground conditions, locate existing services and plan site access. We stage the excavation to suit the ground support system and keep erosion controls in place as work progresses.

Quality checks

We check excavation levels and arrange geotechnical inspections and fill compaction testing as specified for the project.

Shoring & Piling

We install shoring and piles for excavation support and building foundations, working to the structural and geotechnical design.

Scope of works

  • Excavation support and retaining systems
  • Foundation piling to the specified design
  • Staged excavation and support installation

Construction

We plan rig access, working platforms and the excavation sequence with the project engineers, taking account of nearby structures and services.

Quality checks

We maintain installation records and arrange the inspections and testing specified by the engineer. If ground conditions differ from the design assumptions, we refer them to the engineer before proceeding with the affected work.

03

Stormwater Drainage & OSD Systems

We install stormwater drainage and on-site detention systems, including pipes, pits, storage structures and outlet controls.

Scope of works

  • Stormwater pipes, pits and drainage structures
  • On-site detention storage and outlet controls
  • Connections to approved discharge points
  • Trench backfilling and surface reinstatement

Construction

Drainage levels and alignments are checked against other services before installation. The work is staged with earthworks and road construction to maintain access and avoid clashes.

Quality checks

Before backfilling, we check bedding, pipe levels and connections. We also check detention system components against the approved drawings and provide inspection, test and as-built records at handover.

Sewer & Water Infrastructure

We carry out sewer and water infrastructure works for subdivisions and civil developments, from trench preparation and pipe laying to backfilling and reinstatement.

Scope of works

  • Trenching, bedding and pipeline installation
  • Sewer maintenance structures and water fittings
  • Backfilling, compaction and reinstatement
  • Connections to existing networks

Construction

We plan the work around existing services and the asset owner’s inspection stages. We engage the required authorised providers for work on authority assets and connections to existing networks.

Quality checks

Testing follows the asset owner’s requirements and may include pressure or leakage tests, sewer CCTV and compaction tests. We compile the construction records needed for acceptance.

05

Roadworks & Pavements

We build roads and pavements for subdivisions and development access, including subgrade preparation, granular pavement layers and asphalt surfacing.

Scope of works

  • Subgrade preparation and trimming
  • Placement of pavement subbase and base layers
  • Asphalt surfacing
  • Pavement tie-ins and reinstatement

Construction

We sequence pavement construction around underground services and crossings, and plan site access and traffic arrangements around the roadworks.

Quality checks

We check pavement materials, layer thicknesses, compaction and levels. Inspections and testing are completed at the specified stages before the next layer or surface is placed.

Kerb, Gutter & Concrete Works

We construct kerb and gutter, footpaths, crossings and associated concrete works for subdivisions and civil projects.

Scope of works

  • Kerb and gutter
  • Footpaths, shared paths and access crossings
  • Associated concrete slabs and minor civil structures

Construction

The work covers set-out, base preparation, formwork and reinforcement where needed, followed by placing, finishing and curing the concrete.

Quality checks

We check levels, drainage falls, dimensions and finish against the drawings. We arrange pre-pour inspections and concrete testing as specified for the project.

07

Retaining Walls

We build retaining walls for subdivisions and civil projects, including foundation preparation, wall construction, drainage and backfill.

Scope of works

  • Foundation excavation and preparation
  • Wall construction to the specified system
  • Drainage behind retaining structures
  • Backfilling and compaction

Construction

We build to the engineered wall details and stage the work with surrounding earthworks. Where specified, we arrange foundation inspections before building the wall.

Quality checks

We check wall alignment, drainage and backfill as work progresses. We arrange the engineer’s inspections and compile the required completion records.

08

Demolition & Remediation

CBEM carries out demolition and site remediation for residential and civil developments, preparing sites for earthworks and construction.

Scope of works

  • Demolition of existing buildings and structures
  • Removal of redundant slabs, pavements and footings
  • Contaminated soil excavation and disposal
  • Coordination of asbestos and hazardous material removal

Construction

We review site conditions, service disconnections and the demolition sequence before work starts. Dust, noise and access controls are planned around neighbouring properties. Remediation follows the project requirements, with licensed specialists engaged where required.

Quality checks

We coordinate waste classification, disposal records and the inspections required for the work. Environmental consultants carry out validation sampling where specified, with clearance and validation documentation provided before the next stage begins.
