Division 8 is the CSI MasterFormat section for Openings. It includes doors, frames, windows, storefronts, curtain walls, skylights, louvers, glazing, and the hardware required to operate them. It is one of the most code-sensitive scopes in commercial construction.

How long does a Division 8 takeoff take?

For a typical commercial project, a skilled Division 8 estimator can complete a full takeoff in 2–4 business days. The timeline depends on the number of openings, hardware complexity, and drawing quality. AI-assisted workflows can reduce turnaround further. OSTE.AI typically delivers bid-ready Division 8 takeoffs within 48–72 hours.

What is included in a Division 8 takeoff?

A complete Division 8 quantity takeoff includes doors, frames, windows, storefronts, glazing systems, louvers, and door hardware schedules. Each opening is quantified by type, size, material, fire rating, and hardware set. Deliverables are usually organized by CSI subsections such as 08 11 00 Metal Doors and Frames, 08 14 00 Wood Doors, 08 41 00 Entrances and Storefronts, and 08 71 00 Door Hardware.

How much does a Division 8 takeoff cost?

The cost of a Division 8 takeoff depends on project size, drawing complexity, and turnaround requirements. Outsourced Division 8 estimating services typically range from under $100 to several hundred dollars per project. OSTE.AI offers Division 8 takeoffs starting at a flat $89 per division, per project, with standard turnaround times of 48–72 hours.

What is a hardware set in Division 8?

A hardware set is the grouped list of components required to operate a door. This may include hinges, locksets, exit devices, closers, thresholds, weatherstripping, kick plates, silencers, and electrified hardware. Hardware sets are identified in the Division 8 specifications and assigned to openings in the door schedule.

Can AI handle a Division 8 takeoff on its own?

AI can automate repetitive parts of a Division 8 takeoff, including door tag detection, schedule extraction, and quantity organization. However, experienced estimators are still needed to review fire ratings, specification conflicts, hardware coordination, and addenda changes. The most accurate results come from a hybrid workflow that combines AI speed with human quality control.
