Request Installation DocumentsPrepare the Site and Foundation
Before Units Arrive
Most installation problems are caused by poor site preparation, not by the container unit itself. Before delivery, the site team should confirm ground level, foundation points, drainage direction, unloading access and utility connection positions.
Site preparation: level ground, concrete foundation points, drainage slope, truck access and unit placement area.
- Level and compact the installation ground before unloading.
- Prepare concrete blocks, strip foundation, slab foundation or other approved support according to project design.
- Confirm all foundation points are aligned with the final layout.
- Plan drainage direction to avoid water accumulation under or around the units.
- Keep enough space for truck access, crane operation, forklift movement and temporary storage.
- Mark water inlet, drainage outlet and electrical connection points before installation starts.
Important: Foundation design should be checked by the buyer, local engineer or project contractor according to local soil conditions, wind load, usage requirements and regulations.

Installation Crew Planning
Installation requirements depend on product type, unit size, site condition and assembly method. A small local team can usually support standard positioning and basic assembly, while flat pack and foldable units may require lifting equipment and more coordinated site work.
- Wrenches, screwdrivers and spanners
- Electric drill and cutting tools
- Measuring tape and level tools
- Sealant gun and waterproofing tools
- Ladders, scaffolding or working platform when required
- Crane or forklift depending on unit weight and unloading method
- Lifting belts, hooks and rated lifting points
- Guide ropes for positioning
- Temporary supports if required by the assembly sequence
- Site supervisor for layout and safety coordination
- Skilled workers for frame and panel assembly
- Qualified electrician for final electrical connection

Request Pre-Assembly ChecklistStandard Container Unit
Installation Process
Standard container units are normally faster to position and connect because the main structure is already assembled or semi-assembled before shipment. The key work on site is foundation placement, leveling, alignment, joint sealing and final inspection.
Position the unit on the prepared foundation points.
Check level, alignment and door/window opening condition.
Connect adjacent units if a multi-unit layout is required.
Seal roof joints, side joints and connection points according to the installation reference.
Inspect interior finish, accessories, doors, windows, lights and sockets before handover.
Accommodation units, container offices, guard rooms, site cabins and small modular buildings where fast site setup is required.

Assembly Process
Flat pack container units are designed for efficient shipping and on-site assembly. The assembly sequence should follow the supplied drawings to ensure correct frame alignment, panel installation, roof fixing and waterproof sealing.
Flat pack units ship in compact stacks. Frame, columns, wall panels and roof components are assembled on site in sequence.
Place and level the bottom frame on the prepared foundation.
Install columns and check vertical alignment.
Install wall panels according to the panel sequence.
Assemble roof frame and roof panels.
Install doors, windows and accessories.
Apply sealing, check fixing points and complete interior finishing checks.
Panel sequence, bolt fixing and roof sealing should be checked carefully during installation. Incorrect sequence may increase assembly time and cause rework.

House Installation Process
Foldable and expandable container houses are suitable for projects that require fast deployment, relocation or temporary accommodation. Compared with flat pack assembly, the main installation work is lifting, unfolding, locking, fixing and connection checking.
Place the folded unit on the prepared foundation or support points using rated lifting equipment.
Open the side sections or folding structure according to the required sequence.
Fix locking points, check structure, seal joints and prepare utility connection.
Temporary camps, emergency housing, remote site offices and projects where fast setup and relocation flexibility are important.
