Services
Specialist tunnelling and trenchless advisory across the full project lifecycle.
Independent. Practical. Built from forty years on the kit.
We support owners and design teams from concept through delivery — starting with the ground, ending with a bid that goes out cleaner than it would have without us.
Four pillars. Engage at any stage. Early involvement pays back most, while constructability still costs nothing to change.

PILLAR 01
Feasibility & Strategy
Make the right call before the design locks.
WHAT WE DELIVER
THE OUTCOME
detailed design starts with options properly tested, a brief that survives tender, and cost confidence the funder can stand behind..
PILLAR 02
Design & Planning Support
Embed buildability before it's expensive to add.
- Option assessment through concept and detailed design
- Safety in Design workshops from G1
- Construction Execution Plans — method, sequence, risk
- Independent constructability review at design milestones
WHAT WE DELIVER
THE OUTCOME
The design that goes to tender is one a contractor can build — without redesigning it under ECI. The methodology stands up to scrutiny from regulators, neighbours, and counsel.
- Equipment selection matched to site, project and ground considerations
- Tender evaluation on capability, safety, and value
- Contract negotiation under 3910, 3916, NEC, FIDIC
- Pre-bid WorkSafe documentation (PHMP, PCP)
- Mobilisation and start-up assurance
PILLAR 03
Procurement & Delivery
Buy the right capability. Hold the contract together.
WHAT WE DELIVER
THE OUTCOME
The right team mobilises on the right kit with the right paperwork. Claims that would have arrived don't. Relationships hold because the contract was built to flex.
PILLAR 04 — Digital Access & Project Intelligence
Delivered through our product suite — Planner, Monte Carlo and the AI-Enabled Platform. Subscription products, separate from the consulting above.
