FAQ

What does a tunnelling & trenchless consultant do?

We provide expert guidance on project planning, feasibility, design, cost estimation, risk management, construction methods, program allowances and safety considerations for tunnelling and trenchless projects.

Do you use digital tools or AI – and does that replace a tunnelling consultant?

HarkerWize uses bespoke digital tools, including the TrenchlessIQ app and a secure inhouse knowledge platform that utilises an AI based NLP to enable question based research of your project to speed up knowledge transfer.
TrenchlessIQ helps screen trenchless and tunnelling options, identify key risks, and provide indicative cost and CO₂e ranges. These tools do not replace specialist advice – they support it. We still work closely with clients to interpret results, develop construction schemes, and ensure that what’s developed maximises opportunities, is buildable, safe, and commercially robust.

At what stage should I engage a tunnelling consultant?
