Below grade is its own trade.
We're building the next generation of software for underground utility contractors — from AI-powered plan reading, project management and construction intelligence, to field calculators, estimating, scheduling and planning tools. The future of underground construction is here.
Construction intelligence for the office. Field calculators for the hole. Both built for the same scope of work — and nothing else.
Your underground construction engineer, estimator, and project advisor.
Ask questions the way you'd ask your senior PM.
Request early access →Every calculation an underground contractor reaches for — organized in one place.
Built to work where the work happens.
TrenchLineCalcs.com →Every calculation, recommendation, and project document is developed using recognized engineering references, published standards, and accepted industry practices.
Every result can be traced back to its formulas, assumptions, references, and intended application — creating a transparent record that supports confident project decisions.
Trusted references. Transparent assumptions. Defensible decisions.
