The Scope-Split Checklist — Every Line Gets an Owner
Every modular purchase arrives holding a brochure. Run its scope through these six tests before you sign: the honest verdict each produces, and what to do with the lines that pass.
| The test | How it runs — and what it decides |
|---|---|
| "Show me the split: every element of the finished building, assigned to a named engineer." | The split test — the document test. Box, foundation, seams, laterals, site-built elements, each with a designer of record. A split that exists as a contract exhibit passes. A split described as "standard" or "handled" has told you its real state: it will be authored later, by events, at your prices. |
| "Which regime approves this factory work for my state — and where is the label paperwork?" | The regime test. The answer names a state program or its recognized agency, an approval of this plant's design for your state, and the label each unit will carry. "Approved in our home state" for a project in yours is the market's most common approval trick, and this test is its whole cure. |
| "Who designs my foundation — from what soils basis, against which published loads, delivered when?" | The loads test. The site engineer designs to the plant's loads and anchor pattern; both documents — the geotechnical basis and the plant's load publication — have dates. A foundation promised before either exists is a guess with a signature on it. |
| "What is the largest unit, and what does its route legally allow?" | The road test — the envelope examination. Dimensions checked against every jurisdiction on the actual route, with the carrier's survey and permits named. A seller who must "check with logistics" has measured the road the way you are about to pay for it: later, and urgently. |
| "Who details, who performs, and who inspects the marriage lines — before they are closed?" | The seam test. Three names per crossover class — structural, water, waste, electric, HVAC, fire continuity. Fluency here is the good that modular marketing counterfeits; this test assays the metal. |
| "What does my local counter still permit and inspect — and which of its approvals gate my date?" | The counter test — the one about the schedule. Foundation permit, set inspection, crossover sign-offs, occupancy — sequenced against the delivery. An honest seller maps the counter's gates onto your calendar. A seller who calls the building "pre-approved" has graded your credulity instead. |
Then, the Doors
Whichever offers survive the six tests, the last step is the same: compare them against the published methodology — and start with the evaluated firms whose answers to these tests are stated on this site, crossing by crossing: the five evaluated firms.
Who Publishes This Directory
Published by Apex Grid Engineering PLLC. The firms evaluated and listed on this site today are the publisher's own family of brands — this is an affiliated directory, not a neutral referee. The methodology below is the standard any engineering firm can be measured against, and it is the standard we hold our own firms to in public. Presentation order on this site is the publisher's choice and an experiment in what helps buyers decide — it is not an objective quality verdict, and no firm pays for placement. Coverage claims are limited to licensure the operator's bench actually holds, stated per state. No reviews, ratings, or project claims are published for any firm unless they can be documented — this site explains how a buyer should judge a modular purchase and publishes the publisher's methodology assessments; it does not publish customer reviews, and you will find none invented here.
Operated by Apex Grid Engineering PLLC. Founder & CEO: Jeremy “Chico” Mills — serial entrepreneur and USAF veteran. Jeremy is the founder and chief executive; he is not a licensed professional engineer, and no page on this site implies otherwise. The engineering behind the listed firms is performed and sealed by their licensed PE benches.
