A scope takeoff checklist by CSI division

The divisions estimators most often under-scope on commercial work, and the question to ask on each one before the bid goes out.

Already a customer? Log in

A scope list is only useful if it is complete. These are the divisions where scope most often goes missing on commercial and institutional bids, and one question to ask on each before you send packages.

01 General Requirements

Who is carrying temporary facilities, cleanup, and closeout documentation? If it is not on a sub, it is on you.

03 Concrete

Are slab-on-grade, foundations, and site concrete split the way your subs bid them? Vapor barrier and under-slab insulation are the usual orphans.

05 Metals

Miscellaneous metals — railings, embeds, lintels — are frequently excluded by the structural steel bidder. Confirm who has them.

07 Thermal and Moisture Protection

Roofing warranty terms and flashing at penetrations. The spec section usually says more than the roof plan does.

08 Openings

Hardware, glazing, and hollow metal frames are three different subs on many jobs. Make sure the frames are not counted twice or zero times.

09 Finishes

Floor prep and moisture mitigation. Almost always a scope fight later if it is not written down now.

22 / 23 / 26 Plumbing, HVAC, Electrical

Controls, commissioning, and low-voltage. Ask which bidder is carrying each, in writing.

31 / 32 / 33 Earthwork, Exterior, Utilities

Where does the site sub stop and the utility sub start? Five feet outside the building is a real answer; “at the building” is not.

Working from a draft

PreConstruct reads the plans and specs and drafts the scope list by division, with the source page on each line, so this checklist becomes a review instead of a blank sheet. See AI Scope Takeoff.
