You hold the budget. You carry the risk.
The decisions in front of you deserve the right voice in the room.
For Asset Owners & Scheme Funders
Independent specialist input for the people funding tunnelling and trenchless schemes — anywhere in the world.
You have a scheme to deliver. The work runs underground. The decisions are big.
Where You're Standing
You have an asset to renew, a corridor to unlock, a network to extend, or a resource to reach. The route runs underground, the methods are specialist, and the decisions you make in the next few months will shape the cost and outcome for years. You've briefed your consultant and asked for options.
Optioneering is a long road by necessity. Consenting requires alternatives to be considered and discounted on the record, so the chosen scheme can be defended if challenged. The risk isn't that options get studied. The risk is that without specialist input at the table, the wrong options stay live for too long, the buildable ones don't get the depth they need, and the path to a fundable, defensible scheme takes more time and cost than it should. Fees grow. Programmes shift. The board begins to ask questions.
This isn't anyone's fault. Tunnelling and trenchless work sits at the specialist end of a wide engineering field, and most design teams don't have someone who has actually built it sitting at the table. Without that voice in the room, optioneering naturally widens before it narrows, and unbuildable ideas survive longer than they should. The cost shows up in your budget, your programme, and your board papers.
What if you had an independent specialist sitting on your side of the table — someone with decades on the tools, who can tell you in the first conversation which options are real, which need more work, and which can be set aside?
The Shift
That's HarkerWize. Independent of your consultants. Independent of your contractors. Working only for you.
01
Problem definition
We help you sharpen the brief before the project gathers momentum — clear problem statement, defined constraints, agreed success criteria. The whole team works better when the brief is precise.
02
Option development & refinement
We work alongside your design team to bring constructability thinking into every option on the table. Buildable ideas get strengthened. Less viable ones get identified earlier, so the strongest options move forward with confidence.
03
Cost confidence for funding
P50, P70, P90 cost ranges your funders, board, or treasury can defend. Backed by Monte Carlo modelling and decades of delivery data — built to stand up to scrutiny.
04
Business case support
Trenchless and tunnelling sections of business cases — written or reviewed for funder requirements, treasury rules, infrastructure commission templates, or whichever regime applies in your jurisdiction.
05
Consenting & approvals strategy
Understanding what regulators, neighbours, and stakeholders will scrutinise — and what to address upfront. A clearer path to the approvals you need.
06
Procurement strategy
Choosing the right contract model, the right packaging, the right risk allocation. Getting the work to market in a form that draws strong bidders and sets the project up to succeed.
What We Bring to the Owner's Table
The Owner's Difference
Two ways the next twelve months play out.
Without HarkerWize
- Optioneering takes longer than expected as scope grows.
- Less buildable options stay live longer than they should.
- Cost confidence in the business case is harder to defend.
- Consenting risks emerge late and reshape the programme.
- Cost and time pressure builds before construction begins.
With HarkerWize
- Optioneering closes faster with clearer direction.
- The strongest options get the depth they deserve.
- Funder-ready cost ranges in the business case from day one.
- Consenting risks identified early and addressed in design.
- A defensible scheme heading to market with confidence.

Mining & Resources
Access declines, ventilation tunnels, conveyor drifts, ore passes, dewatering schemes. Mine operators and resource sector clients across hard-rock and soft-ground environments.
Transport & Major Infrastructure
Road and rail tunnels, service crossings, utility relocations. Road controlling authorities, rail operators, port authorities, airport operators.
HarkerWize works with asset owners and scheme funders on tunnelling and trenchless projects across multiple sectors and jurisdictions.
New Zealand-based, globally engaged. Work spans local utility schemes through to multi-kilometre infrastructure tunnels for international clients across multiple sectors.
How We Engage With Owners
Strategic Advisory
Retained or per-project advisory across multiple schemes. We sit alongside your infrastructure or capital projects team as the trenchless and tunnelling specialist on call. Scope: from problem definition through to handover.
Project-Specific Support
Engaged on a single scheme — feasibility, business case, procurement, or delivery. Lump-sum or daily rate, scoped to the gate or milestone. NDA standard.
Independent Review
An independent specialist view on constructability, cost, programme, or risk for a scheme you're about to commit to. Useful when stakes are high and decisions are imminent — a second perspective from someone who has built the work.
Digital Decision Support
Faster answers, even before you brief a consultant.
The TrenchlessIQ platform gives asset owners decision support in hours, not months. Drop in your alignment, your constraints, your project context — get a method shortlist, indicative cost ranges, risk red flags, and CO₂e comparisons before you spend a dollar on consultant fees.
Whether you're shaping a new infrastructure scheme, working through feasibility, or building the case for funding — start with a conversation. We'll tell you in plain language whether HarkerWize can help, and how.
