"Trenchless cost blowouts aren't bad luck. They're baked in at concept stage."
UNDERGROUND INTELLIGENCE
The damage isn't done on site. It's done at the front end — when the right options were never on the table and the baseline was already too thin to defend.
You already know the pattern.
A scheme goes to tender with a method that "should work." Geotech is patchy, so the contractor prices the gap. ECI begins, redesign follows, the programme slips. A claim lands. Then another. Margin's gone before anyone has broken ground.
This isn't a one-off. It's a structural gap in how trenchless work gets framed, scoped, and priced. The same five failure points show up project after project.
01
Narrow options
Opportunity left on the table at concept stage.
02
Fuzzy constructability
ECI bias drives redesign and delay.
03
Geotech baseline gaps
Patchy GI weakens cost confidence.
04
Slow optioneering
Margins compress, programmes slip.
05
Contract complexity
3910 / 3916 / NEC / FIDIC amplify claims and method risk.
Every one of these is a margin-killer. Every one is fixable - but only if someone with a builder's instinct gets in early.
Forty years of hands-on trenchless delivery, now sitting on your side of the table. Not an academic. Not a generalist. Not a contractor with skin in the bid. We're not bidding the work - we're making sure it can be bid, built, and defended.
THE SOLUTION
HarkerWize. Built from the tunnel face up.
We plug in where influence is highest: pre-feasibility, concept, and the early design gates - across every trenchless method, from microtunnelling to shaft construction.
"We simplify the complex, so you can move forward with certainty."
PILLAR 01
Feasibility & Strategy
Make the right call before the design locks.
PILLAR 02
Design & Planning Support
Embed buildability before it's expensive to add.
PILLAR 03
Procurement & Delivery
Buy the right capability. Hold the contract together.
PILLAR 04
Digital Access & Project Intelligence
Decision-support products. See spotlight below ↓
WHAT WE DO
Compatible with NZS 3910 / 3916, NEC and FIDIC. We work the way your project is already structured.
DIGITAL ACCESS
Three products. One purpose: faster, smarter decisions.
Tools that complement, not replace, expert advice. Built from forty years of project experience - codified, so your team can use it on demand.
Planner
Method shortlist, risk, cost, CO₂e - in an afternoon.
Monte Carlo
P10 / P50 / P90 numbers funders accept.
AI-Enabled Platform
Project knowledge, sourced and audit-ready, in Teams.
THE STAKES
Both paths leave the same concept gate. One climbs. One slides. The fork is set before anyone breaks ground.
With HarkerWize
The path that climbs.
Without HarkerWize
The path that slides.
Two paths. One choice.
THE CALL
If this sounds like your project, let’s talk.
You stop firefighting trenchless risk. You start designing it out. That's the work. That's what HarkerWize is for.
