A submittal is the package a contractor sends to the design team for review before work is fabricated or ordered: shop drawings, product data, samples and sometimes calculations or certifications. Each one is logged against a specification section, reviewed by the architect or engineer of record and returned with a stamp that says whether fabrication can proceed; Plumb reads its shop drawings against 14 categories before it goes.
The stamps vary by firm but come down to four responses. Approved, or no exceptions taken: build it as drawn. Approved as noted: build it with the reviewer's marks incorporated, no resubmittal required. Revise and resubmit: the package goes back to the shop, gets corrected and re-enters the queue. Rejected: it does not meet the contract documents and starts over.
Every cycle restarts the reviewer's clock, which many contracts measure in weeks, and fabrication waits for the stamp. The usual causes of a resubmittal are documentation gaps rather than design problems: a missing finish callout, a material grade that disagrees with the schedule, a detail that contradicts a general note.
How Plumb uses the term
Tier 2 — Submittal Readiness Review checks a package for engineering readiness and submittal completeness before it leaves the shop, every finding placed on the sheet it came from. It is on every plan, including Anytime Review. See /pricing.
