Project planning
The finished room footprint is only part of the site plan.
Mark delivery access, unloading position, expansion zones and installation equipment areas.
Coordinate support locations, floor levels and utility entries with the model drawing and local professionals.
Agree who supplies installation labor, performs connections and completes testing and required inspections.
Transport and deployment
Start by confirming the actual product format. SunlitTec’s T-series references describe expansion-box and folding formats; the current model drawing should establish the frame, room layout, packed state and expanded state for your order. An expandable container house brief should specify these points rather than assume a standard freight-container construction.
Use the table to compare like-for-like dimensions. Send the customization team your available site envelope and required equipment, then compare the quotation with the container and prefab format checklist.
Before you inquire
No. Compare deployed dimensions with deployed dimensions and packed dimensions with packed dimensions. Ask for usable interior area separately.
The project still needs the agreed supports, services, assembly checks, commissioning and local approvals. Confirm readiness responsibilities before dispatch.
