Before the line runs: a modular plant's front end
A new Arizona plant for modular homes asked Common Ground to look at how it should take in and price its leads. I led that analysis, and I treated the front end as the part of the business that protects the line.
The seat
This was a Common Ground engagement, July to August 2026, and I led it. I tested the plant's business from several seats before handing leadership a document to adopt.

What I was brought in to decide
The client is a company spinning off into volumetric modular homes. It designs, builds and sets them from its own factory line in Arizona, aimed at workforce and low-income housing, and a new plant is coming online. The company stays unnamed here.
It brought in Common Ground to do an initial analysis of its business model, with the plant's front end at the center. How does it read a lead, put an early price on it, and steer a developer toward a signed feasibility agreement? A factory is a fixed cost whose line has to keep running. What keeps it running gets decided on the first calls and with the first number, well before a box is built. Its chief executive brought in most leads through his own network, and he wanted the front end designed before he chose who would run it.
What we did
- I skipped the memo around the hypothetical project in the brief. Instead I took a real two-story rental community of about 200 units, one I had bid before through the plant, and ran it as if it were live. I took it from the first thin lead through to a drafted feasibility agreement. Every recommendation therefore had to stand up to real plans and a real local trade market.
- We laid out the front end as a pipeline with gates between stages. The stages are intake with a first call, a free rough estimate, a paid feasibility package, and last a handoff to preconstruction. Every stage has an entry test, a named output and a gate decision.
- We divided every budget in two. Common costs are the same whoever builds the units. Vertical delivery is where stick framing, panel systems and volumetric modular truly compete. That lets a developer compare methods on the one scope where they differ.
- The estimate came out of Kanopi, LÏEF's estimating engine. Two blind quantity takeoffs were run separately and reconciled against each other. Its band is plus or minus 15 percent, and its exclusions are printed on its face. A figure for comparison, recalled from an earlier project, turned out to run high by double digits against the original document, and we caught it before the number shipped. Source before memory became a written rule, and never tune an input to hit a target sits next to it.
- Schedule led every page. A factory builds units indoors while the site is being graded, and at this scale the cost of carry, interest and rent not yet collected outweighs a small gap in construction cost.
- Everything deeper than the rough estimate sits behind a fixed-fee feasibility agreement. The fee is nonrefundable once work starts, the work is delivered within 21 days, and the fee is credited 100 percent against a build contract signed within 180 days. The fee itself tests whether a developer is real.
- I tested the business behind the plant from five seats. They were plant operations, housing finance, tax and incentives, then labor cost and technology. Each seat left leadership one open question from me.
Results
- The analysis took one week to deliver. The core package was built on the day the brief came in.
- In the worked example, the factory route ran about 14 months. The two site-built routes ran 18 to 19 months. For that reason schedule opens every page of the pitch.
- Leadership got two things to adopt: an operating document for the front end and a risk register for pursuits. Common Ground put nothing in place, because the work was analysis.
The lesson
Build the front end that protects the line before anything else. A pipeline with no qualification gate exposes the factory to every unqualified lead.
