The Scope Gap Index / Division 13
Division 13 · Special Construction · Q3 2026
39 Division 13 packages across 21 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 13 packages across 21 projects, 17 July to 30 September 2026
of 39 had at least one flag from Scope Agent
flags in total: 191 inferred, 38 coordination
packages flagged for testing, inspection and certification, all 18 as inferred
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
Prefabricated structures, modular units, pools. Scope Agent flagged an anchor, embed or connection in 20 of 39 packages, 18 as inferred: the modular box lands on the foundation and the documents don’t say who sets the anchor bolts or who grouts the gap. Testing is second at 18, every one inferred: the pool pressure test, the factory inspection of the module, the third-party certification the building department wants to see.

“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 (25 of 39) is left out; see the method note.
Beyond the ranking
Of 229 flags, 191 were inferred and 38 coordination. A special construction package is usually a manufacturer’s scope, written around the product, and the site work that receives the product is where the flags land.
Thirty-four packages had at least one flag, 87 percent. As with equipment, a package that reads supply and deliver gives Scope Agent nothing to flag. The setting, connecting and testing live somewhere else, or nowhere.
Blocking, backing and support drew 15 flags, 11 inferred and five coordination. Sealants drew 11, ten inferred and three coordination. The joint where the modular unit meets the site-built corridor, the sealant at the pool coping, the backing for the prefabricated canopy. Each one is a hand-off the documents show without naming.
The items in detail
The six jobs flagged most often, after the generic supply-versus-install topic. Check your own documents before assuming a flag is right.
Anchor bolts and embeds in the foundation for the prefabricated structure, the connection between modules, the pool shell to the deck, the service connections to the unit. Eighteen inferred, five coordination. Name who supplies and sets each anchor, who surveys it, and who makes each connection.
Factory and field inspection of modular units, the pool pressure and leak test, third-party certification, the engineer’s letter the authority wants. All 18 flags were inferred. Make each test and certificate a deliverable with a named trade.
Temporary support for modules during set, backing in the module walls for site-installed items, the bearing for a prefabricated canopy. Eleven inferred, five coordination. Say who supports what and until when.
The joint between modules and between module and site-built work, the pool coping sealant, the flashing where the prefabricated roof meets the main roof. Ten inferred, three coordination. Name the trade that seals each interface.
Foundation tolerances the module setter needs, the gap between modules, the pool shell against the deck finish. Ten inferred, one coordination. State the tolerances and who verifies before the set.
Protecting set modules before the envelope is closed, and protecting the finished pool through the rest of the job. All six flags were inferred. Say who protects and for how long.
Method
39 scope packages classified to MasterFormat Division 13, generated by Scope Agent between 17 July and 30 September 2026 on 21 of the 24 projects in the quarter’s cohort. Nine carried the trade label special construction, eight prefabricated structures, seven modular manufacturers, and nine a pool or swimming pool label. Six more 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.
39 packages on 21 projects clears our 20-package threshold for publishing a division, and one package moves a share by about three 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.
Upload your drawings and specs. Scope Agent flags the inferred and coordination scope before the bid leaves your office, and your estimator decides what’s real.
