Keeping roadheader excavation moving on North East Link — project photograph from the original case study

North East Link - Roadheader Spoil Removal

Keeping roadheader excavation moving

Continuous spoil removal behind a roadheader left no room for downtime or non-compliant plant. Six tunnel-spec dump trucks arrived configured and ready.

Tunnel-spec excavation for cross passage works — project photograph from the original case study

North East Link - Cross Passage Works

Tunnel-spec excavation for cross passage works

Cross-passage excavation inside an active TBM environment, where only fully tunnel-spec plant could go underground. An 8T breaker package was built for exactly that.

Precision grade control underground on North East Link — project photograph from the original case study

North East Link - Cut and Cover Tunnel Section

Precision grade control underground

Precise underground excavation needed grade control without GPS signal in confined conditions. Two reduced-radius Volvo excavators were configured with Trimble UTS control.

Supporting schedule-critical tunnelling excavation works — project photograph from the original case study

Lower Plenty Cut and Cover - Spark North East Link

Supporting schedule-critical tunnelling excavation works

Hard-rock production in a restricted excavation envelope against a fixed TBM breakthrough milestone. A short-stick 35t CAT with a Montabert hammer was configured for it.

Excavators, a skid-steer and crews working beneath a concrete deck between large concrete pillars during underground excavation

North East Link - Lower Plenty D-Walls

Maintaining TBM progress with a specialist rock saw

Cement-treated crushed rock up to 600mm thick was packing the blade and stalling the saw. We reconfigured the rock saw with tungsten-carbide pick teeth.

Eliminating manual reo cutting on D-wall breakout works — project photograph from the original case study

North East Link - Lower Plenty Cut & Cover

Eliminating manual reo cutting on D-walls

Reinforcing steel high on a D-wall face needed cutting inside a constrained shaft. A guarded excavator with rotating shears provided the reach for machine cutting.

Precision payload management on the Eastern Freeway Upgrade — project photograph from the original case study

Eastern Freeway - Bourke to Tram (EBTA)

Precision payload management

No space for a weighbridge on a constrained live site, with overloaded trucks the risk. Onboard weighing and 3D GPS came fitted to two excavators.

Specialist drilling support for Kananook Stabling Yard — project photograph from the original case study

Kananook Stabling Yard

Specialist drilling support

Unstable ground in a live rail corridor risked bore collapse. An excavator-mounted vibrator installed steel casings before auger drilling to maintain hole integrity.

Compact laser-controlled grading for confined infrastructure works — project photograph from the original case study

North East Link EBTA - Crane and Piling Pads

Compact laser-controlled grading

Crane and piling pads needed precise levels in a work zone too tight for a grader. A laser-controlled compact track loader did the trimming.

Cutting contaminated soil disposal costs by over $70,000. — project photograph from the original case study

Talbot Crescent Habitat Park

Cutting contaminated soil disposal costs by over $70,000

Contaminated soil disposal threatened the council's budget. An ALLU screening bucket on the client's excavator processed material on site, avoiding a larger screening plant.

Precision trenching in basalt for commercial works — project photograph from the original case study

Commercial concrete contractor - services trenching

Precision trenching in basalt

Services trenches through dense basalt risked slow excavation and overbreak with hammering. A diamond rock saw on the client's excavator cut precise edges instead.

Two Focus Machinery Cat excavators beside a rock face on the Eastern Freeway Upgrade, with a Hushtec-shrouded breaker and drum cutter

Eastern Freeway Upgrade - Burke to Hoddle

Low-noise rock excavation for night works

Night excavation near homes faced strict noise and vibration limits. Zero-swing excavators, a Hushtec-shrouded breaker and a drum cutter enabled work within those limits.

Supporting major rail breakthrough works — project photograph from the original case study

LXRP - Dandenong Rail Underpass Breakthrough

Supporting major rail breakthrough works

A tunnelling breakthrough beneath rail infrastructure needed continuous production in constrained conditions. Late-model excavators and specialist attachments arrived configured to the Ready-to-Dig standard.
