A four-day enclosure timeline is the kind of number that invites skepticism, and it should — a schedule claim is only useful if you know precisely what it covers. PanLbilt's demonstrated example was a 2,475 SF two-story shell closed in four days of on-site assembly. Here's what that means in practice.
What's inside the four days
The four-day window covers the field assembly sequence once panels arrive on a prepared foundation: setting and connecting wall panels, installing the second-story floor and framing, and enclosing the roof. In PanLbilt's own build sequence, that breaks down roughly as:
- Days 1–2 — wall and floor panel assembly
- Days 3–4 — second-story assembly and roof enclosure
By the end of day four, the structure is a closed shell — weathertight, with the building envelope complete.
What's outside the four days
This is the part schedule comparisons often blur, and it's worth being explicit about. The four-day figure does not include:
- Engineering review — confirming drawings, elevations, loads, code criteria and openings before panels are fabricated
- Panel fabrication — the factory production run for the project's numbered panels and connection details
- Logistics and foundation readiness — shipment coordination, crane access, staging and a prepared, inspected foundation waiting on-site
- Interior fit-and-finish — in PanLbilt's demonstrated project, occupancy readiness followed roughly 30 days after the shell closed
None of that is unique to panelized construction — every method has design, fabrication or procurement lead time before the first stick or panel goes up. The point of isolating the four-day figure is that it's the portion of the schedule where panelized assembly diverges most from conventional framing: less sequential trade work, less weather exposure, less time the structure sits open.
How to compare it fairly against your current method
The right comparison isn't "four days versus how long framing usually takes" as a generic industry figure — it's four days versus your project's current framing sequence, on the same square footage, stories and site conditions. A useful way to structure that comparison:
| Decision factor | Your current baseline | What to model against PanLbilt |
|---|---|---|
| Enclosure schedule | Your current framing-to-dried-in timeline | Panel fabrication lead time + field assembly window |
| Weather exposure window | Time structure sits open during framing | Reduced exposure during the shorter assembly window |
| Field labor sequencing | Sequential multi-trade framing crew | Crane-set assembly crew requirements |
| Fabrication lead time | Material ordering and delivery schedule | Factory panel fabrication timeline |
This is the same framework used in PanLbilt's own field proof section — the goal isn't to claim panelized construction beats every method on every project, but to give you the inputs to run the comparison against your specific numbers.
