For Tier 1 Consultants
Specialist trenchless input-without skin in the bid.
You're leading the design. Trenchless is one of several methods on the table. You don't have a deep specialist on the team - and bringing a contractor in this early creates conflicts you'd rather avoid.
You need someone who knows what tunnelling, microtunnelling, pipejacking, HDD, guided boring, pipe rehabilitation, and shaft construction can actually deliver in the ground we have - and isn't trying to win the build.
That's what HarkerWize is for.

Six Ways We Support Your Design
Engagement
Lump-sum or daily rate. Scoped to the gate or milestone. NDA standard. We work inside your team.
Deliverables
Memos, registers, GBR mark-ups, review reports. Written so your design team can use them directly.
Independence
We don't tender for the build. We don't have a parent contractor. What you see is what you get.
How It Works
Send us your alignment, your geotech, and the gate you're heading into. We'll tell you in plain language what we can add.
