AI-Powered and Estimator-Reviewed CSI Division Takeoffs
OSTE combine fast AI tools with hands-on construction expertise to deliver precise, CSI MasterFormat-aligned quantities for all CSI divisions in 48–72 hours.
We understand the pressure behind every bid conflicting schedules, missed accessories, and the hidden costs of a count done too fast. That’s why every OSTE takeoff is reviewed by an experienced estimator, fully marked up, and delivered with clear exclusions and assumptions you can stand behind at any scope review.

Our Mission, Vision & Core Values
MISSION
Deliver precise, CSI MasterFormat-aligned takeoff quantities that save estimators time, eliminate hidden scope risks, and let them focus on the parts of bidding that actually move the needle – pricing, value engineering, and building client trust.
VISION
Become the default “send us your plans when you’re slammed” partner for US specialty subcontractors and general contractors. We aim to expand CSI coverage across every division and keep pricing fair and sustainable so good estimators never have to choose between burnout and bad bids.
CORE VALUES
Transparency Over Speed
Every takeoff includes marked-up PDFs showing exactly what was counted, plus clear exclusions and assumptions.
Accuracy Through Review
AI handles the repetition; construction-experienced estimators handle the judgment.
Sustainable Pricing
$89 flat per division because we want repeat customers, not one-time transactions.
No-Nonsense Accountability
If something’s off, we own it and fix it – fast.
Why Our Approach Actually Works in the Field
We didn’t build this from a tech playbook. We built it from the trenches of commercial estimating – where schedules contradict specs, hardware gets missed, and midnight counts cost real money.
Division 08 & 10 Specialists
Deep focus on doors, frames, hardware, toilet partitions, lockers, wall protection - the items where schedules fight plans and specs fight reality. We cross-check everything so you don't get surprised later.
CSI Structure from Day One
Quantities organized by MasterFormat so your team, subs, suppliers, and architects are all on the same page during RFIs and scope reviews.
Industry-Tuned Process
We understand VE cycles, addendum timing, and how missed quantities turn a winning number into a losing one. That's why every report is estimator-reviewed - not just auto-generated.
