Commercial HVAC and Mechanical Estimating Services
Tribuild takes off HVAC and mechanical by system: ductwork by weight and area, piping by size and linear foot, and equipment counted by tag, with air devices, controls, and insulation carried so the full mechanical scope is priced.
Mechanical bids ride on ductwork weight and piping length. Tribuild takes off HVAC and mechanical by system, duct by weight and area by gauge and pressure class, hydronic and refrigerant piping by size and linear foot, and equipment counted by tag from the schedules.
Air devices, dampers, controls, insulation, and supports are carried per the documents, TAB is allowed by device count, and every deliverable ships with documented assumptions your team can price and defend.
What we estimate for hvac and mechanical
Ductwork
Supply, return, and exhaust duct by weight/area by gauge and pressure class.
Duct fittings
Elbows, transitions, and taps quantified with the duct runs.
Air devices
Diffusers, registers, and grilles counted by type from the schedule.
Dampers
Fire, smoke, volume, and balancing dampers counted by type.
HVAC equipment
RTUs, AHUs, VAVs, fans, and split systems counted by tag from the schedule.
Controls
Control devices and points counted/allowed per the sequence and schedule.
Hydronic piping
Chilled- and hot-water piping by size and linear foot with fittings.
Refrigerant piping
Refrigerant line sets by size and linear foot.
Steam and condensate
Steam and condensate piping by size and linear foot where applicable.
Insulation
Duct and pipe insulation by area and linear foot per the spec.
Supports
Hangers, supports, and seismic bracing by allowance/linear foot.
Accessories
Access doors, flex, curbs, and specialties counted by unit.
Testing and balancing
TAB scope allowance per the number of devices/systems.
Demolition
Removal of existing mechanical quantified for disposal.

Frequently asked questions
Mechanical plans, equipment and air-device schedules, control sequences, piping and duct details, and specifications. Schedules drive equipment and device counts.
By weight and area by gauge and pressure class, with fittings carried, so fabrication and installation labor are priced correctly.
Controls are counted/allowed per the sequence and schedule, and testing-and-balancing is carried as an allowance per device/system count.
Yes, each piping system is measured on its own by size and linear foot with the appropriate insulation.
