| 1. Define the Application |
Confirm how the mobile container will be used and where it will be installed. |
Site office
Accommodation
Classroom
Retail unit
Sanitary unit
Typical design inputs include occupancy, floor area, climate, wind exposure, utility connections, fire-risk category, and expected service life.
|
Project brief, site photographs or drawings, intended-use statement, local planning requirements, and utility specifications. |
1–5 business days for a clearly defined project. |
Use local building, fire, accessibility, electrical, and sanitation rules as design inputs rather than treating the unit as a standard freight container only. |
| 2. Select the Container Format |
Choose the transportable module size and whether it will be used as a single unit or a connected system. |
Common external ISO container footprints are approximately:
• 20 ft: 6.06 m × 2.44 m
• 40 ft: 12.19 m × 2.44 m
• High-cube versions: approximately 2.90 m external height
Internal dimensions vary by construction, insulation, doors, and service equipment.
|
General arrangement drawing, dimensional drawing, connection details, lifting points, stacking limits, and transport weight statement. |
2–7 business days for preliminary layout selection. |
Verify road, port, crane, and final-site access limits. A high-cube or heavily fitted module may exceed local transport-height or weight limits. |
| 3. Confirm Technical Specifications |
Freeze the structure, envelope, interior finishes, openings, equipment, and utilities. |
Typical specification items include insulated wall and roof panels, floor loading, windows, doors, HVAC capacity, plumbing fixtures, lighting, sockets, distribution boards, kitchen or sanitary equipment, and corrosion protection.
|
Approved shop drawings, material schedule, structural calculations where required, electrical single-line diagram, plumbing diagram, equipment datasheets, and finish schedule. |
3–10 business days, depending on customization. |
Check that the selected materials and systems are suitable for the destination climate, including humidity, temperature range, salt exposure, snow, wind, and seismic conditions where applicable. |
| 4. Establish the Import Classification |
Ask the customs broker to determine the correct classification for the complete shipment and any separately shipped equipment. |
Classification can differ according to whether the shipment is an empty container, a prefabricated building module, a steel structure, furniture, electrical equipment, HVAC equipment, or sanitary fittings. |
Commercial invoice, packing list, product description, material composition, declared value, country of origin, transport document, and any required import permits. |
Usually 3–10 business days before shipment if the documentation is complete. |
Do not rely on a generic container code without broker confirmation. The importer remains responsible for accurate declaration, duties, taxes, and restricted-goods checks. |
| 5. Review Destination-Country Compliance |
Confirm whether the module requires approval as a building, electrical installation, transportable structure, workplace, accommodation unit, or combination of categories. |
Common review areas include structural safety, fire resistance, thermal performance, energy efficiency, ventilation, accessibility, plumbing, wastewater, electrical safety, and local occupancy rules.
|
Certificates or test reports required by the destination authority, structural design documents, fire-performance evidence, electrical test records, and installation manuals. |
2–8 weeks is common for authority review, but the period varies significantly by country and project type. |
Obtain written confirmation from the local authority, licensed engineer, architect, or compliance consultant before production of highly customized units. |
| 6. Verify Electrical Compatibility |
Match the electrical system to the destination supply and local installation rules. |
Confirm nominal voltage, frequency, phase arrangement, plug and socket type, protective devices, earthing method, cable requirements, ingress protection, emergency lighting, and generator or solar integration if applicable.
|
Electrical schematic, load schedule, insulation-resistance test, continuity test, protective-device test, equipment manuals, and local inspection records where required. |
1–3 weeks for specification and document review. |
Do not energize the module until a qualified local electrician has checked the incoming supply, earthing, protection, and final connections. |
| 7. Confirm Manufacturing and Quality Control |
Approve the final drawings and define inspection points before fabrication begins. |
Suitable checkpoints include frame inspection, welding inspection, dimensional inspection, insulation and sealing review, water-ingress check, equipment commissioning, finish inspection, and final packing review.
|
Signed drawing approval, inspection and test plan, material certificates where applicable, factory inspection report, punch list, photographs, and final packing list. |
Typical production is 4–12 weeks after design approval, depending on quantity and customization. |
Record all deviations before dispatch. Confirm serial or unit references, component quantities, spare parts, keys, manuals, and loose items against the packing list. |
| 8. Prepare Export and Shipping Documents |
Coordinate the shipment method, delivery term, insurance, and customs responsibilities. |
Possible transport arrangements include containerized sea freight, breakbulk shipment, flat-rack transport, or specialized road delivery. The correct option depends on module dimensions, weight, lifting points, and destination access.
|
Commercial invoice, packing list, bill of lading or sea waybill, certificate of origin if required, insurance certificate, export declaration, fumigation or wood-packaging evidence where applicable, and lifting instructions. |
1–3 weeks for booking and document preparation; ocean transit varies by route. |
Confirm whether freight is quoted for one complete module or for knocked-down components. Check port handling, demurrage, customs clearance, inland haulage, and unloading costs. |
| 9. Prepare the Destination Site |
Make the foundation, access route, utilities, drainage, and lifting area ready before arrival. |
Site preparation may include a level concrete slab, strip foundations, screw piles, or other engineered supports. Requirements depend on soil, local frost depth, drainage, wind, seismic conditions, and structural loads.
|
Site survey, foundation plan, soil information where required, utility connection plan, drainage plan, lifting plan, and local permit documents. |
2–8 weeks, depending on civil works and permitting. |
Measure gate widths, turning radii, overhead clearances, road restrictions, crane reach, ground bearing capacity, and the distance from unloading point to final foundation. |
| 10. Delivery and Unloading |
Arrange safe access, traffic control, lifting equipment, and qualified personnel. |
Common equipment includes a suitable mobile crane, truck-mounted crane, forklift for approved loads, lifting beams, spreader equipment, slings, and rated shackles. Equipment capacity must be based on actual module weight and lifting radius.
|
Approved lifting plan, lifting-point details, weight statement, risk assessment, method statement, delivery booking, and local road or traffic permits where required. |
One day for unloading is common when access and equipment are ready. |
Never lift from unapproved points or by improvised methods. Keep personnel outside the suspended-load exclusion zone and follow local occupational-safety rules. |
| 11. Installation and Connection |
Position, level, connect, seal, and commission the module or modular group. |
Installation may include anchoring, joining modules, installing stairs or ramps, connecting power, water, drainage, HVAC, fire systems, data, and external weather seals.
|
Installation manual, anchor details, connection drawings, commissioning records, electrical and plumbing test results, fire-system records, and local sign-off documents. |
1–10 days for a simple unit; larger multi-unit projects may require several weeks. |
Check level, anchor torque, water tightness, door and window operation, drainage slope, electrical protection, HVAC operation, emergency exits, and accessibility features. |
| 12. Final Acceptance and Handover |
Complete the inspection, resolve defects, and obtain approval for use. |
Handover should cover structure, finishes, equipment, utilities, safety systems, spare parts, cleaning, operating instructions, maintenance intervals, and warranty responsibilities. |
Handover checklist, as-built drawings, operation and maintenance manuals, inspection certificates, warranty terms, training record, final invoice, and defect close-out report. |
1–5 business days for inspection and close-out of a standard unit. |
Document the condition at handover and identify which items are covered by the supplier, installer, importer, building contractor, or local utility provider. |
