Write the product requirements before names
Start with the intended use and whether the building is temporary, relocatable or meant to stay. Record floor area, clear height, room count and the service life the buyer expects. A 12 ft by 40 ft module and a 24 ft by 60 ft assembly are different purchases even when both are called modular. Add the transport envelope: travel width and travel height are separate route constraints. Give the carrier the actual loaded dimensions and ask it to confirm route, permits and unloading equipment; the project lift planner must confirm the crane lift plan.
Supplier matching then asks factories for the same brief. FramePoint Sourcing sends the written use, dimensions, quantity and destination to manufacturers of alternative systems. Replies are lined up only after each one states what is included. A homepage product family is not treated as an approved project solution.
