What you receive

- Mechanical quantity takeoff workbook (Excel- quantities only, no pricing)- Marked-up drawings showing measurement locations and routing- Written summary of scope interpretation, assumptions, and exclusions (including rationale for judgement-based quantity decisions)- Flattened PDF snapshot of baseline quantities for reference

Method and Background

Takeoffs are prepared manually by a former commercial HVAC installer and estimator, with scope interpretation based on how projects are actually built- not automated extraction.The focus is on constructability-aware quantities that align with how projects are actually built, informed by over a decade of field and preconstruction experience in the San Francisco Bay Area, supporting commercial projects across office, TI, and institutional work.

Pricing & Engagement

Pricing is project specific
Takeoff packages are scoped and quoted after a brief review of the drawing set. Most projects are reviewed and quoted within one business day.Fees are based on:
- Drawing set size & complexity
- System density & scope clarity
- Required turn-around timeTypical takeoff delivery is 2-5 business days with expedited options available.This service is intended for professional estimating teams who value accuracy, documentation, and schedule reliability over automated quantity extraction.
