Infrastructure and Industrial Contractors
Water and Wastewater Construction Estimating
Tribuild supports water and wastewater contractors with multi-discipline quantity takeoffs: process concrete structures, process piping and equipment, and mechanical, electrical, and I&C scope, built from the drawings for treatment-plant and pump-station bids.
Treatment-plant bids are multi-discipline by nature: process concrete, piping, equipment, mechanical, electrical, and I&C on one job. Tribuild quantifies each process area: cast-in-place structures by volume with reinforcing and waterstop, process piping by material and service, and equipment counted by tag.
Mechanical, electrical, I&C, and sitework are carried for the disciplines approved for delivery, and every deliverable ships with documented assumptions (including the field and existing-plant risk that stays with the contractor) your team can price and defend.
What we estimate for water and wastewater contractors
Water-treatment plants
Treatment-process structures and systems by area and discipline.
Wastewater-treatment plants
Wastewater-process structures and systems by area and discipline.
Pump stations
Pump-station structure, pumps, and piping counted and measured.
Lift stations
Lift-station wet well, pumps, and controls counted by unit.
Process piping
Process and yard piping by size, material, and linear foot.
Process equipment
Clarifiers, blowers, screens, and process equipment counted by tag.
Tanks and basins
Cast-in-place and package tanks/basins by volume and unit.
Concrete structures
Process concrete (walls, slabs, channels) by volume with reinforcing and waterstop.
Underground utilities
Yard piping and utilities by size and linear foot.
Valves and pumps
Process valves and pumps counted by type, size, and rating.
Mechanical systems
HVAC and plant mechanical scope by system.
Electrical systems
Power and distribution for the plant by system and count.
Instrumentation and controls
Instruments, SCADA tie-ins, and control points by loop/point.
Sitework
Earthwork, yard piping, and site improvements by volume and area.

Frequently asked questions
Process, structural, mechanical, electrical, and I&C drawings, the equipment list, P&IDs, civil/yard plans, and specifications. These support a multi-discipline takeoff.
We quantify the disciplines approved for delivery on the engagement (process concrete, piping, equipment, mechanical, electrical, I&C, and sitework) and state which are included.
By structure and volume with reinforcing and waterstop carried, since water-holding structures have detailing that drives cost.
Means and methods, final pricing, and licensed engineering remain with the contractor and design team.
