Infrastructure and Industrial Contractors
Transportation Infrastructure Estimating Services
Tribuild supports transportation contractors with quantity takeoffs across heavy-civil scope: pavement, earthwork, drainage, structures, and MOT, built from the plan and profile so bid items are quantified to the drawings.
Heavy-civil transportation bids are pay-item driven. Tribuild builds quantity takeoffs from the plan, profile, and cross-sections, pavement by section and station, earthwork balanced from surfaces, and drainage, barrier, signage, and structural quantities counted, and aligns to the owner's schedule of bid items where one is provided.
Maintenance-of-traffic is quantified by phase, structural concrete and steel are carried by structure, and every deliverable ships with documented assumptions (including the field and subsurface risk that stays with the contractor) your team can price and defend.
What we estimate for transportation infrastructure
Highways and roadways
Roadway pavement and section quantities by area and station.
Bridges
Bridge concrete, steel, deck, and railing quantities by structure.
Tunnels
Tunnel lining and structural quantities where applicable.
Transit stations
Station structural and finish quantities by area.
Rail infrastructure
Track subgrade, ballast, and civil quantities (trackwork by others where noted).
Airport infrastructure
Airfield pavement and civil quantities by area and section.
Pavement
Asphalt and concrete pavement by area, section, and station.
Drainage
Storm drainage pipe, structures, and culverts by linear foot and unit.
Barriers
Guardrail, barrier, and attenuators by linear foot and unit.
Signage
Overhead and ground signage counted by unit.
Lighting
Roadway and structure lighting counted by unit with conduit.
Structural components
Retaining walls, abutments, and structural concrete/steel by quantity.
Utility relocations
Utility relocation quantities coordinated with the civil scope.
Sitework
Earthwork cut/fill, subgrade, and aggregate by volume and area.
Maintenance of traffic
MOT phasing quantities, signage, barrier, and temporary pavement by phase.

Frequently asked questions
Plans, profiles, cross-sections, the schedule of bid items (where provided), pavement and structural details, and specifications. Cross-sections drive earthwork.
Yes, where an owner schedule of quantities is provided, we align the takeoff to those pay items for direct bid entry.
Yes, MOT quantities (signage, barrier, temporary pavement) are separated by phase per the traffic-control plans.
Means and methods, final pricing, and any licensed engineering remain with the contractor and design team. We provide quantity estimating support.
