Late construction-type decisions can trigger additional fire-rating requirements, testing and engineering judgements. Here's why confirming the approach early matters for modular projects.
Construction type helps consultants define project requirements. For a modular manufacturer, it also affects major cost drivers from the outset, particularly fire-rating requirements.
The key lesson: Confirm the construction type early and review the applicable fire ratings, listed assemblies and code requirements with the modular provider. This helps the team identify gaps before they become late testing, engineering judgements or schedule problems.

Construction type is more than a consultant's classification.
For the modular manufacturer, it establishes requirements that can affect cost, fire-rating coordination and delivery timing.
Early alignment allows the design and manufacturing teams to review the requirements together, before changes become more disruptive.
