Underground Utility Estimating and Takeoff Services
Tribuild takes off wet and dry utilities from the civil plans and profiles: pipe by size and linear foot, structures counted by type, and trenching, bedding, and restoration carried so each utility run is priced from surface to invert.
Utility bids are priced from the profile, not just the plan. Tribuild takes off wet and dry utilities from the civil plans and profiles (pipe by size and linear foot with real depths) and derives the trenching, bedding, and backfill each run actually needs.
Manholes, catch basins, hydrants, and valves are counted from the schedules, wet and dry systems are kept separate, surface restoration is quantified by type, and every deliverable ships with documented assumptions (including the subsurface risk that stays with the contractor) your team can price and defend.
What we estimate for underground utilities
Domestic water
Domestic water main and services by size and linear foot with fittings.
Fire water
Fire service and loop piping by size with thrust blocks and fittings.
Sanitary sewer
Gravity sanitary piping by size and linear foot with depth from the profile.
Storm drainage
Storm pipe by size and linear foot with depth and slope from the profile.
Natural gas
Gas main and service piping by size and linear foot.
Electrical duct banks
Concrete-encased and direct-bury electrical duct banks by linear foot and configuration.
Communications duct banks
Telecom duct banks and innerduct by linear foot.
Manholes
Sanitary, storm, and electrical manholes counted by type and depth.
Catch basins and inlets
Catch basins, inlets, and area drains counted by type.
Hydrants
Fire hydrants and assemblies counted by unit.
Valves and structures
Gate/butterfly valves, vaults, and utility structures counted by unit.
Trenching
Trench excavation by linear foot and volume by depth from the profiles.
Bedding and backfill
Pipe bedding and select backfill by volume per the trench detail.
Utility restoration
Surface restoration over trenches by area and type.

Frequently asked questions
Civil utility plans and profiles, the structure schedule, trench and bedding details, and specifications. Profiles drive depth, trenching, and bedding quantities.
Yes, water, fire, sanitary, and storm (wet) plus gas, electrical, and communications duct banks (dry), each quantified by size and linear foot.
Yes, trench volumes and bedding/backfill are derived from the pipe profiles and trench details, not a flat assumption.
Yes, manholes, catch basins, hydrants, and valves are counted, and surface restoration over trenches is quantified by area and type.
