Scope checklists by trade: all 25, one index

Each of the 25 checklists below covers one trade's real scope — what's actually theirs, what's routinely written into someone else's section instead, and what gets missed because of it. They're grouped by CSI MasterFormat division, same as a project manual, so if you already know which division your dispute lives in, you can go straight there.

Six of these boundaries come up often enough — and cut across enough trades — that they got their own longer, deeper treatment instead of a paragraph inside a trade page. Those are linked at the bottom, under "Read further."

Division 02 — Existing Conditions

Trade	Where it usually bites
Demolition	The designated-substances survey is the real bid, not the demolition drawings

Division 03 — Concrete

Trade	Where it usually bites
Concrete forming	Who owns placing and vibration decides who owns honeycombing found at strip
Reinforcing steel	Embeds — anchor bolts, sleeves, connection plates — sit in no trade's scope more often than any other single gap
Concrete supply	The exposure class table that sets your mix price is usually on the S-sheets, not in the concrete section
Concrete finishing	The FF/FL numbers that actually price the job routinely hide in Division 01

Division 04 — Masonry

Trade	Where it usually bites
Masonry	Loose lintel supply is steel's, installation is masonry's — on most sets, not all

Division 05 — Metals

Trade	Where it usually bites
Steel	Base plate grouting is the single most litigated gap between steel and concrete
Miscellaneous metals	A bollard on the civil sheet, a ladder on the mechanical detail — none of it lives near the metals spec

Division 06 — Wood, Plastics and Composites

Trade	Where it usually bites
Rough carpentry	The backing every other trade assumes you'll frame in is never handed to you as a list
Millwork	Backing is drywall's material, but its location comes from millwork's own shop drawings

Division 07 — Thermal and Moisture Protection

Trade	Where it usually bites
Waterproofing	A 14 to 28 day concrete cure precondition, stated once, can own your whole schedule
Roofing	The curb sizes that drive your flashing labour usually sit in someone else's section
Firestopping	Divisions 21–28 routinely disclaim it at their own penetrations by default
Cladding	The panel schedule prices the panels — not everything around them

Division 08 — Openings

Trade	Where it usually bites
Doors and hardware	Whether this trade installs what it supplies changes tender to tender
Glazing	Slab-edge fire safing at curtain wall gets claimed — or disclaimed — by two packages at once
Specialty doors	The run from disconnect to motor gets argued on nearly every job that has one

Division 09 — Finishes

Trade	Where it usually bites
Drywall	The Level 5 finish clause is hiding in the painting section
Flooring	Moisture testing decides who pays, and the curing-compound clause is in concrete's section
Painting	The clause deciding whether Level 4 drywall finish is acceptable is written here, not in drywall's section
Interior finishes	Demountable partitions are routinely a separate supplier-installed system hiding inside this section

Division 14 — Conveying Equipment

Trade	Where it usually bites
Conveying equipment	The hoistway tolerance clause is the single most common delay claim on an elevator job

Divisions 21–23 — Mechanical

Trade	Where it usually bites
Mechanical	Every scheduled unit needs a starter, VFD or disconnect, and the schedule almost never says whose

Division 26 — Electrical

Trade	Where it usually bites
Electrical	The Division 23/26 starter boundary and fire alarm's four duties both live here

Divisions 31–33 — Site and Infrastructure

Trade	Where it usually bites
Site work	The geotechnical report is the real bid document, and the rock line depends entirely on how "rock" is defined

Some boundaries above show up often enough, and cross enough trades, to deserve more than a paragraph:

• The Division 23/26 boundary, exhaustively — starters, VFDs, disconnects, duct detectors, and interlock wiring, checked unit by unit.
• Fire alarm's four duties — why bids miss one — device installation, wiring, programming, and verification, and why the last two fall through together.
• The geotechnical report as the real site-work bid document — rock, unsuitable material, dewatering, and how to read one in 20 minutes.
• How construction scope disputes actually get resolved — the patterns that repeat across every trade above, in one piece.
• Construction tender terms, for Canadian ICI subcontractors — the vocabulary these checklists assume you already know.
• CCDC contracts, plainly — what a subcontractor actually needs to know about the standard-form contract most of these tenders sit on.
