A Submittal Readiness Review is Plumb's Tier 2 review. It includes Tier 1 plus engineering readiness and submittal completeness against the applicable jurisdictional profile: whether the package carries what a submittal reviewer, an engineer of record or a building department will expect to find, such as calculations, seals, product data, quality-control and special-inspection requirements, and the open items that would otherwise come back as an RFI.
The boundary matters. Tier 2 checks whether the information required for review is present and consistent. It does not perform the engineering review, judge whether a design is adequate or decide what a jurisdiction will accept. Anything that needs a code or engineering determination is isolated and flagged for the engineer or architect of record and the authority having jurisdiction.
The deliverable is the same as Tier 1: a marked-up PDF, an Excel comment log and an online viewer, every finding placed on the sheet it came from and marked PE-Review-Required or not.
How Plumb uses the term
Tier 2 is for permit-bound work, engineering submittals and anyone who reviews submittals for others. It is available on every plan, including Anytime Review, and the deliverable arrives within 24 hours. See /pricing and how it works.
