Interior Finishes and Architectural Trades
Doors, Frames, and Hardware Estimating Services
Tribuild builds your opening count from the door schedule: doors, frames, and hardware sets carried opening by opening, with fire ratings, electronic hardware, and access-control coordination flagged so nothing on the schedule is missed.
Division 08 is a scheduling problem before it's a pricing problem. Tribuild builds your opening count directly from the door schedule (every opening carried with its door, frame, and hardware set) and reconciles it against the plans so the count you bid matches the count you'll buy.
Fire ratings are verified opening by opening, electronic hardware and access-control openings are flagged for coordination, and every deliverable ships with a reconciled opening-by-opening schedule and documented assumptions your team can price and defend.

Frequently asked questions
The door schedule, hardware schedule/sets, floor plans, frame and jamb details, and specifications. The schedule drives the opening count and hardware assignment.
Yes, hardware is quantified by hardware-set number so each opening is priced to its specified set rather than a generic allowance.
Rated openings are flagged and verified against the schedule with rated doors, frames, and hardware carried accordingly.
Openings with electrified hardware are flagged and quantified; low-voltage device scope is coordinated but typically provided by the security trade.
