The Scope Gap Index / Division 04
Division 04 · Masonry · Q3 2026
22 Division 04 packages across 20 projects, generated between 17 July and 30 September 2026 for Provision customers, ranked by how often each job got flagged. Model flags, checked by a person on fewer than one item in a hundred. Where to look, not proof.
Division 04 packages across 20 projects, 17 July to 30 September 2026
of 22 had at least one flag from Scope Agent
flags in total: 556 inferred, 120 coordination
jobs flagged in more than three-quarters of the packages, the densest ranking of any division
Inferred means Scope Agent judged the job necessary and found no scope naming who does it. Coordination means it judged the job to sit between two trades. Neither is a confirmed omission on that project.
Ranked
Masonry has the densest ranking on the Index: nine of the sixteen topics were flagged in 17 or more of the 22 packages. Penetrations lead at 20 of 22, and every one of the 20 carried an inferred flag. The masonry package describes the wall. It doesn’t say who sleeves the duct through it, who sets the lintel over the opening, or who puts up the scaffold to lay the top course.

“Inferred” and “coordination” count packages with that kind of flag, and a package can have both, so the two columns can add to more than the total. The generic supply-versus-install topic (20 of 22) is left out; see the method note.
Beyond the ranking
Of 676 flags, 556 were inferred and 120 coordination, more than four in five. A masonry package is usually one sub on one wall, so there’s rarely a second trade in the argument. The documents just don’t say who does the job next to the wall.
Masonry is the scaffolding trade, and Scope Agent still found 18 of 22 packages silent on it: 18 inferred flags, none coordination. Who supplies, who erects, who engineers it above the threshold height, and whether the siding sub gets to use it afterwards. One sentence each.
Openings, cutting and patching drew 17 flags, and 14 of those were coordination flags, the highest coordination count in the division. Lintels, frames built in as the wall goes up, the hollow-metal frame the door sub delivers late, the block cut around the electrical sub’s box. Each one is a hand-off, and the documents show the opening without naming the hands.
The items in detail
The nine jobs flagged in more than three-quarters of the packages. Check your own documents before assuming a flag is right.
Sleeves through the block for mechanical and plumbing, block-outs for ducts, coring after the wall is up when a sleeve was missed, and firestopping every one of them in a rated wall. Twenty inferred, six coordination. Say the mason builds in sleeves supplied by each trade, require a combined penetration drawing before the wall starts, and name who firestops.
Wall ties to the backup, anchors for the steel sub’s relieving angles, the embed for the handrail post, bearing plates for joists. Nineteen inferred, 13 coordination. Put the anchor and embed schedule in the masonry scope, name who supplies each item and who sets it.
Through-wall flashing, weeps, control joint sealant, the joint between the masonry and the window frame. Eighteen inferred, ten coordination. Say whether the mason installs flashing supplied by the waterproofer or the reverse, and who seals the control joints.
Getting block, brick and mortar to the working deck on every floor. Eighteen inferred, one coordination. State who provides the hoist or the forklift, who loads the floors, and whether the mason’s price carries it.
The scaffold itself: supply, erection, engineering, inspection and dismantle. All 18 flags were inferred. Name the trade, name the duration, and say which other trades may use it.
Plumb and level tolerances the glazing sub will hold the mason to, coursing to match the door frames, the interface with the stone veneer. Seventeen inferred, four coordination. Specify tolerances by element and say who measures.
Temporary bracing of walls during construction, bearing for lintels, support for built-in items. Fifteen inferred, eight coordination. Say who braces, to what standard, and when the bracing comes down.
Building frames in, forming openings for louvres and equipment, cutting block around what other trades install late, patching afterwards. Thirteen inferred, 14 coordination. Decide whether the mason builds every opening on the drawings or cuts them later, and who pays for the cutting.
Removing existing masonry on renovation work, cutting new openings in old walls, and hauling off cut block and mortar waste. Seventeen inferred, two coordination. Put demolition of existing masonry in one scope and waste removal in the mason’s.
Method
22 scope packages classified to MasterFormat Division 04, generated by Scope Agent between 17 July and 30 September 2026 on 20 of the 24 projects in the quarter’s cohort. Nineteen carried the trade label masonry. Three carried a customer-specific label we couldn’t map to a standard trade; they’re counted here because the package itself was coded to the division. A package is one trade on one project, as it stood at quarter end. An item counts when Scope Agent flagged it as inferred or coordination. We grouped the items into sixteen topics by keyword, and one item can land in more than one topic.
Twenty-two packages on 20 projects clears our 20-package threshold for publishing a division. It’s small enough that one package moves a share by about five points, so treat the ranking as an order and the percentages loosely. These are Provision customers’ projects, and the numbers describe this sample only. A flag is Scope Agent’s judgment, checked by a person on fewer than one item in a hundred, so some flags will be wrong. We’ll update it every quarter.
