Preparing Your Site for the Delivery and Installation of Prefabricated or Container Houses
1. Complete a Site Survey Before Delivery
A site survey provides the information needed to assess whether the proposed location is ready for delivery and installation.
The survey should review:
The proposed installation location and site boundaries
Ground conditions and the general condition of the installation area
Site levels, drainage, and potential water accumulation
Available working space around the building
The locations of nearby buildings, trees, walls, utility poles, and overhead lines
Access for transport vehicles and lifting equipment
The planned positions of utility connection points
Any restrictions that could affect unloading, lifting, assembly, or final positioning
Site information should be recorded clearly and compared with the approved project drawings. Where soil conditions, foundations, drainage, structural interfaces, or other technical matters require professional assessment, the project owner should obtain confirmation from the relevant qualified local professionals.
2. Check the Transport Route and Site Access
The transport route should be reviewed before dispatch. A route that appears suitable for ordinary vehicles may present restrictions for larger transport equipment or a prefabricated building component.
The review should consider:
Road width and turning areas
Low bridges, tunnels, gates, and overhead obstructions
Sharp bends, steep slopes, narrow sections, and soft ground
Road surface and seasonal access conditions
Vehicle height, width, length, and manoeuvring requirements
Local traffic restrictions, permits, and access rules
The final approach from the public road to the unloading position
Coordination with road authorities, property managers, or neighbouring landowners where necessary
The transport plan should be based on the actual dimensions and handling requirements confirmed in the project documents. Local transport specialists should verify route suitability and any required permissions before the shipment is arranged.
3. Prepare a Suitable Unloading Area
The unloading area should be available, clear, and accessible when the shipment arrives. It should provide enough space for the transport vehicle, lifting equipment, installation personnel, and safe movement around the building.
Before delivery, confirm that:
The unloading area is free of stored materials, vehicles, debris, and other obstructions
The ground is suitable for the expected site activities and equipment
The area is reasonably level or has been prepared according to the approved plan
There is sufficient clearance for lifting and positioning
A safe separation can be maintained between workers, vehicles, and lifting operations
Temporary barriers, signs, lighting, or traffic controls are available if required
Weather and ground conditions will not create unnecessary handling risks
If the planned unloading area changes, the revised arrangement should be reviewed before the vehicle arrives. Do not assume that an alternative area will be suitable without checking access, ground conditions, lifting clearance, and installation sequence.
4. Confirm the Foundation or Installation Surface
The foundation or installation surface must be ready before the building is delivered. Its form and requirements depend on the approved design, site conditions, and product configuration.
The project team should confirm:
The foundation or support arrangement shown in the approved drawings
Dimensions, levels, and positions of relevant support points
The condition and cleanliness of the installation surface
Drainage provisions and the treatment of surface water
The location of reserved openings, anchors, fixings, or connection points where applicable
Tolerances and interfaces that must be checked before placement
Whether local engineering or inspection approval is required
Foundation, soil, structural, and load-related matters should be reviewed by qualified professionals responsible for the project. Do not rely on general installation guidance where local ground conditions, building regulations, or project-specific structural requirements apply.
5. Coordinate Lifting and Final Positioning
Lifting and positioning should be planned before the building or components arrive. The lifting method must match the approved handling information and the equipment available at the site.
The lifting plan should address:
The lifting equipment required for the confirmed load and reach
Ground conditions and equipment setup locations
Lifting points or approved handling locations
Rigging, slings, spreader equipment, and other accessories
Clearances from buildings, trees, overhead lines, and other obstructions
Communication between the lifting operator, signal person, and installation team
Wind, rain, visibility, and other weather conditions
The sequence for lifting, aligning, securing, and releasing the load
A controlled exclusion zone around the lifting operation
Lifting operations should be carried out by competent personnel using suitable equipment and procedures. The final method must be confirmed by the responsible lifting professional and comply with applicable local requirements.
6. Coordinate the Assembly and Installation Sequence
Installation is more efficient when the project team agrees on the work sequence before delivery. This is particularly important when several trades or contractors will work on the same site.
Before installation, clarify:
The planned arrival and unloading sequence
Which team is responsible for each installation activity
The order of structural assembly, enclosure work, interior work, and finishing
The timing of equipment and material deliveries
Areas reserved for temporary storage
Required tools, access equipment, and temporary facilities
Inspection points before the next installation stage begins
The process for recording changes, defects, or incomplete work
All parties should work from the same approved drawings and instructions. Any changes to the installation sequence should be communicated to the project manager and reviewed for their impact on safety, quality, access, and utilities.
7. Prepare Water, Electrical, and Other Utility Interfaces
Utility connections should be planned before installation so that the relevant connection points are available when required. The exact arrangement depends on the approved product information and project design.
The project team should confirm:
The locations of water, drainage, electrical, communications, and other interfaces
The route and protection of incoming and outgoing services
The availability of temporary power or water during installation, if needed
The responsibilities of the building supplier, contractor, and local utility specialists
Required inspections, testing, approvals, and connection procedures
Protection against water ingress, damage, contamination, or unauthorised access
The final connection sequence in relation to installation and commissioning
Electrical, plumbing, drainage, and other regulated work must be completed or checked by appropriately qualified local professionals. Connections should follow the approved project documents and applicable local requirements.
8. Establish Site Safety Controls
A safe installation site requires preparation before the transport vehicle and lifting equipment arrive.
The site safety plan should address:
Site induction and access control
Personal protective equipment
Vehicle and pedestrian separation
Lifting exclusion zones
Working at height and access equipment
Manual handling and pinch-point risks
Temporary electrical supplies and cable management
Weather monitoring and stop-work conditions
Emergency contacts, first-aid arrangements, and evacuation procedures
Fire prevention and safe storage of materials
Housekeeping and waste removal
The site manager or responsible contractor should communicate the safety rules to everyone involved. Local occupational health and safety requirements must be followed, and any task-specific risk assessment should be completed before work begins.
9. Prepare the Project Document Pack
A complete document pack helps the installation team work from consistent information and supports a clear handover.
Depending on the project, the pack may include:
Approved layout and installation drawings
Product specifications and handling instructions
Packing lists and component schedules
Transport and unloading arrangements
Lifting information and site-specific lifting plans
Foundation or installation-surface details
Utility interface drawings
Installation sequence and work instructions
Inspection and testing records
Care, maintenance, and operating information
Applicable permits, approvals, or inspection records
Contact details for the project owner, contractor, supplier, and technical representatives
The document pack should be reviewed for consistency before delivery. Only verified documents relevant to the actual product and project should be issued to the site team.
10. Inspect the Shipment on Arrival
An arrival inspection should take place before unloading is completed or installation begins. The inspection helps identify visible transport damage, missing items, or discrepancies at an early stage.
The receiving team should check:
The condition of the packaging and external surfaces
Signs of impact, deformation, moisture exposure, or other visible damage
Product identification and shipment references
The quantity of units, components, and accessory packages
The packing list against the items received
The condition of lifting points or handling areas
Any loose, damaged, or missing components
Photographic records of the shipment and unloading process
If a problem is found, record it promptly with photographs, descriptions, shipment references, and the names of the relevant parties. Do not conceal, repair, or discard potentially affected items before the issue has been reviewed through the agreed project process.
11. Complete Handover and Installation Records
After unloading and installation, the project team should complete a documented handover. The handover confirms what has been received, installed, inspected, or left outstanding.
The handover record may include:
Delivery and unloading date
Condition report and photographic records
List of received and outstanding items
Installation progress and inspection results
Utility connection and testing records
Open issues, agreed corrective actions, and responsible parties
Final drawings or updated site records where applicable
Maintenance and operating information
Signatures or acknowledgements required by the contract
The handover should reflect the actual condition of the project. It should not be treated as confirmation that all technical, regulatory, or professional approvals have been completed unless those approvals have been formally issued by the responsible parties.
12. Use a Pre-Delivery Readiness Checklist
Before dispatch, confirm that the project team has reviewed the following:
The site survey and access route
The unloading and equipment setup area
The foundation or installation surface
Lifting and positioning arrangements
The assembly sequence and contractor responsibilities
Utility connection interfaces
Site safety controls
The approved project document pack
Delivery contacts and communication procedures
Arrival inspection and handover arrangements
Local permits, inspections, and professional confirmations where required
A documented readiness review allows unresolved issues to be addressed before they affect delivery or installation.
Conclusion
Preparing the site in advance is an essential part of a successful prefabricated or container house project. Clear information, coordinated responsibilities, suitable access, a ready installation surface, safe lifting arrangements, and complete records help the delivery and installation process run in a controlled manner.
Every project is different. Final decisions should be based on the approved product documentation, project drawings, contract requirements, site conditions, local regulations, and confirmation from the qualified professionals responsible for transport, lifting, foundations, utilities, safety, and inspection.
