Use, climate, scale and deployment speed steer the first comparison. We translate those choices into a supplier brief; a local engineer and the selected supplier must still verify structural, fire and permit requirements for the actual destination.
Office, classroom, clinic or camp changes occupancy and interior scope.
Wind, snow, seismic, corrosion and thermal needs depend on location.
Count, dimensions, storeys and clear span affect system choice.
Supplier lead time, transport and site assembly must be compared separately.
A finished room module can reduce site fit-out, but it takes more shipping volume and needs suitable lifting access. A panelized system can pack densely, but joints, lining and weatherproofing demand more site work. Neither is a default winner. Record the route, crane, labor availability and local approval path before deciding.
List dimensions, finishes, MEP boundaries and items packed separately. The selected supplier should confirm revision and applicability.
Record core, thickness, thermal performance and full system fire evidence; neither a core label nor a marketing claim is enough.
Compare packing count, transport envelope, lifting method and site assembly responsibilities. Figures must come from the actual supplier proposal.
Local climate loads and permit route determine the design questions.
Write occupancy, room functions and any hygiene or accessibility needs.
Check route width and module dimensions in mm, 40HQ packing quantity where applicable, port handling, lifting points, crane availability and foundation readiness.
Request wall panel thickness in mm, thermal transmittance in W/m²·K and fire resistance in minutes for the proposed full system, including connections.
State which work happens at the supplier and which happens at the site.
Any certificate or performance claim must be checked against the shortlisted supplier's documents and the project context. ISO container terminology does not mean a modular building carries CSC approval.
Send the project constraints you have confirmed and the questions you need a supplier to resolve.
