Submittal packages for CaptiveAire CORE and TANK — every pipe piece tagged, drawn true to scale, and verified against the controlling design manual before it ships. Reviewed by David Gull, backed by 20 years in fire protection and extensive hands-on CORE and TANK experience.
Keep your existing service software. Bring me the project.
Three real reasons kitchen suppression packages come back. Each one costs you a resubmittal cycle and a schedule slip. Finding them is the job.
The drawing, the parts list and the calculation cannot disagree.
Every pipe piece is tagged, dimensioned and true to scale. The 30° reviewer view is derived and locked from that same arrangement, so the two can never drift apart. Then installed length is checked against the manufacturer's controlling design manual — cited by revision number — and the sheet reads PASS, or it does not leave my desk.

- Controlling design manual — TANK DIM A0029342, June 2026, Rev 25
- Manufacturer job file — hood sizes and MFP date of record
- Order application letter — cited by date and page
- Operating-mode comment — cited by date and page
- Physical-parts ledger — PIPE-02 / PIPE-03, reconciled to this sheet
- Issue history — every revision logged with its reason for change
Example sheet, taken from a real single-cylinder TANK arrangement with the client identifiers removed. Every figure above comes out of one model — change a single pipe piece and the developed length, the flow tally, the parts ledger and the reviewer view all move with it.
Pipe lengths are measurements, not a sketch
Drawn at 1" = 1′ with every piece true to scale, so developed length is something a reviewer can check instead of take on faith.
The isometric is derived, not redrawn
The 30° view is generated from the scaled arrangement and locked to it. Two views of one job cannot contradict each other, because there is only one model.
Installed length checked against the DIM
Installed length against calculation basis, tested to the controlling manufacturer manual at a stated revision. It reads PASS or the package does not ship.
Every number traces to a cited source
The manifest names each source document by date, page and revision. A reviewer with a question can follow it back instead of returning the package to ask.
Sheet index.
It ships under your title block, not mine.
Your company name, your address, your license, your sheet numbering. I don't appear on the package and I never contact your customer. To the owner and the AHJ, your shop produced it — which is as it should be, because your shop is the one accountable for it.

Does it need a PE stamp?
This is the first question every contractor asks, so here is the answer before you fill out anything.
What I do
- Prepare complete, code-correct submittal packages ready to hand to the AHJ
- Produce a scaled piping arrangement with a derived 30° reviewer view, verified against the controlling manufacturer DIM
- Cross-check appliance schedules, nozzle listings, coverage and flow points
- Reconcile a physical-parts ledger against what the drawing actually calls for
- Assemble cut sheets, UL listings and completed jurisdiction forms
- Deliver it all under your title block, your sheet numbering and your preparer's name
- Write the responses when a reviewer returns comments
What I don't do
- Seal drawings or act as engineer of record
- Perform the installation, or certify work I didn't witness
- Pull your permit or submit under your license
- Promise an approval — that decision belongs to the jurisdiction
Three steps, in this order.
The standalone technical review is $99, paid upfront. Submittal preparation is quoted separately.
Send what you already have
Hood drawings, equipment cut sheets, a site photo, a reviewer's comment letter — whatever exists. Incomplete is normal and it is not a problem.
Takes you 5 minutesI find the gaps and price the work
A written list of what's missing or inconsistent, whether your AHJ needs a seal, and a fixed quote for the package. That's the $99 review. The findings are yours whether or not you hire me to build it.
Within 24 hoursYou approve, I build and verify the package
Sheets, ledger, cut sheets and forms come back coordinated and submittal-ready, with the calculation reading PASS. If a reviewer returns comments on my work, I correct and re-issue.
48 hours to 5 business daysOne published price. Everything else is quoted.
A single-cylinder line in a convenience store and a multi-hood hospital kitchen are not the same job, and I would rather quote yours than average it. So the review has a price — and the review is what tells you the cost of the work.
A written gap list, a seal determination for your jurisdiction, and a fixed quote for the package. The findings are yours either way — take them and fix it in house if you'd rather. It's a paid review, not a sales call.
Start a review →Quoted in writing before anything starts.
No hourly billing, no change orders you didn't agree to, and no invoice that arrives larger than the number you approved.
- Quote Fixed, in writing, before work begins. It comes out of the $99 review, so it's priced against your actual drawings rather than a guess.
- Turnaround 48 hours to 5 business days, depending on hood count and whether your jurisdiction reviews in house or sends it to a third party. The quote states the date.
- Rollouts Repeat store formats and multi-site programs get a fixed per-site rate once the first site is verified.
- Questions Your written technical findings are included in the $99 review.
Revisions until approved — no additional charge
On any package I signed off and issued to you as final: if a reviewer returns a comment on my work, I correct it and re-issue at no cost, for as many cycles as it takes. Two things sit outside that, and I'll tell you which before touching anything — changes on your side after issue (equipment swapped, hood drawing revised, an appliance added) and requirements introduced after the fact that were not in effect when the package went out. Those get quoted, not absorbed.
Preparation begins after your quote is accepted and paid, and all required inputs are complete. Jurisdiction response times are outside my control and are not included in turnaround. All permit, AHJ, third-party review and submission fees are excluded and paid by the installer. I prepare and verify documentation; the approval decision belongs to the authority having jurisdiction.
Tell me what you're stuck on.
Two fields to start. Project details only if you have them handy — I'll ask for whatever is missing.
