Shop drawing review already costs a shop a checker's hours on every package, and it costs the project a resubmittal cycle every time a package bounces off the engineer. Plumb's Anytime Review is $25 for 10 sheets, priced from the page count before you pay, with a marked-up PDF, an Excel comment log and an online viewer back within 24 hours.
What a shop pays now
Most shops already pay for drawing review. It is just not on an invoice. It is the checker, the senior detailer or the owner reading the package before it goes out.
How long that takes depends on the package. As an illustrative range, not data: two to four hours for a short package of a dozen sheets, and a full day or more for a forty-sheet package where the schedules, sections and bill of materials all have to agree with each other. Those hours, at the loaded rate of the person doing them, are what one check of one package costs today, before anyone asks whether the check was thorough.
Two things make that cost higher than it looks. The person doing the check is usually the most expensive person in the drafting room. And the check is the task that gets squeezed when the shop is busy, which is exactly when the most packages are going out. A package that leaves with a rushed check is the one that comes back.
What a bounced package costs the project
When the engineer of record returns a package marked revise and resubmit, the cost moves off the shop's timesheet and onto the schedule.
The detailer reworks the sheets. The package goes back through the general contractor's submittal log and waits for the engineer's review again. Material that was going to be ordered off the approved drawings waits with it. If the shop had a slot on the floor for the job, the slot moves or something else fills it. None of that is billed to anyone, which is why it rarely shows up in a cost comparison, and all of it is real.
Each cycle also costs the engineer time, and engineers remember which shops send packages that need two or three passes. That is a reputation cost, and it is the hardest one to put a number on.
Most of what bounces a package is documentation, not engineering: a dimension chain that does not close, a weld symbol with no size, a material grade that differs between the general notes and the bill of materials, a sheet the index lists that is not in the set. Those are the things a second read is for, and they are what the 14 categories are built around.
What Plumb charges
Plumb's pricing is per sheet, and one sheet is one page of the PDF you upload. There are no per-user fees. Every plan comes back within 24 hours with the same deliverable, described below.
Anytime Review
One package, no subscription. $25 covers the first 10 sheets. Every sheet past that is $2.00, on the same checkout. The price is computed from the page count before you pay, so the whole number is on the screen first, and nothing is billed afterward. No upload is refused for being too large.
Anytime Review covers Tier 1 — Buildability Review and Tier 2 — Submittal Readiness Review. It fits a shop that wants to see what a review looks like on its own package, or one that only sends out a few packages a year.
Standard, Shop and Studio
The monthly plans are for shops with steady volume. Each includes a sheet allowance per month, and unused sheets roll over one month.
- Standard: $199 a month for 100 sheets. Tier 1 and Tier 2.
- Shop: $499 a month for 300 sheets. Tier 1, Tier 2 and Tier 3 — Specification Correspondence Review, with the Spec Library.
- Studio: $1,199 a month for 750 sheets. Tier 1, Tier 2 and Tier 3, at the lowest per-sheet rate.
Sheets beyond the allowance are $1.50, the same rate on every monthly plan and every tier, added to the next invoice. An upload over the allowance shows the extra sheets and their cost before it goes in; nothing is held. Plans can be changed in either direction mid-month; the difference is prorated and shown before you confirm. Annual prepay is offered by email, twelve months for the price of eleven.
The free first month
The first month of a first monthly plan is free: 30 days or 50 sheets, whichever comes first, card required. The plan is not charged during the trial, and it can be cancelled from the dashboard before the trial ends. The trial starts at /free-month.
Tier 3, against a spec
Tier 3 — Specification Correspondence Review compares the package against the project specification you supply. It is included on Shop and Studio. Two charges apply on top of the plan: $200 once per specification to parse it into your private Spec Library, where it is reused on every later Tier 3 review for that client, and $0.15 per sheet reviewed against a parsed spec, on the next invoice. The per-sheet fee is not charged during the free month. The parse is a separate purchase, charged when you buy it.
Enterprise
Above Studio volume, or for a company with its own review standards, pricing is by conversation: volume sheet pricing, onboarding and spec parsing included, a dedicated SLA on request. The conversation starts at hello@plumbreview.com.
What is included at every price
The deliverable is the same on every plan. Tier 3 adds a specification section and a compliance matrix.
- A marked-up PDF. Each finding is a numbered bubble on the sheet it came from, linked to a detail card in an appendix at the back. Every finding carries one of five severities (Critical, Major, Minor, Comment or Advisory) and is either flagged PE-Review-Required, meaning it needs a licensed engineer's judgment, or not.
- An Excel comment log, one row per finding, with sheet, severity and the text of the finding, for the shop's own tracking or for a submittal response.
- An online viewer on your dashboard, so the review can be read without downloading anything.
- Delivery within 24 hours of upload. An email says when it is ready.
Every page of the PDF carries a reliance notice. Plumb is not an engineer and does not approve, certify or stamp anything; findings that cannot be backed by what is on the drawing are left out before delivery, so the list is shorter and each item can be taken to the detailer. How it works walks through the upload and what comes back, and the sample review is a real review of a commissioned louver package, so the deliverable can be judged before paying for one.
Which price fits which shop
Anytime Review fits a shop with a few packages a year, or one that wants to try a single package before committing to anything. The monthly plans fit steady volume; the overage rate is the same on all three, so going over an allowance is not a penalty, and the difference between them is the per-sheet rate and whether Tier 3 is included. A shop with spec-driven contracts lands on Shop or Studio, because that is where the Spec Library lives. Everything above that is a conversation.
The number to compare against is not the subscription price. It is the checker's hours on every package, plus the cycles the shop does not control.
