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's sat in that seat - who knows what trenchless methods can actually deliver in the ground you have and isn't trying to win the build.
That's what HarkerWize is for.
