Before a container house arrives, prepare a stable, drained, accessible site with foundations designed for the unit, its intended use, and local ground conditions. Confirm the building layout, delivery route, utility connections, lifting plan, and local permit requirements before finalizing the groundworks. At Hongshun Guangju, we recommend coordinating these details with your supplier and local construction professionals early, because site requirements depend on the specific unit and project. This guide explains what to assess, what to prepare, and what to confirm before installation.
This guide is for property developers, contractors, project buyers, and other teams planning to install a modular or container-style building. It can help you organize site questions before requesting a quotation or scheduling delivery. It is not a substitute for a site survey, structural design, geotechnical advice, or local approvals. Use project drawings and advice from qualified local professionals to determine final specifications.
Site preparation should begin with the intended building layout, not with excavation. Ask your supplier for the unit’s overall dimensions, weight, support locations, connection points, and any installation or lifting instructions available for the selected model. Compare that information with the site plan, access constraints, planned foundations, and utility routes.
For orientation only, common shipping-container lengths are approximately 6.06 m for a 20-foot container and 12.19 m for a 40-foot container. Container-style buildings can differ in length, width, height, and structural configuration, so do not use these figures as final setting-out dimensions. Confirm the exact dimensions and support points on the approved product drawings before marking the site.
Review ownership boundaries, access rights, planning rules, building permits, and any restrictions on temporary or permanent structures. Requirements vary by location and intended use, so confirm them with the relevant local authorities or project professionals. Also check for underground services, overhead power lines, drainage easements, and neighboring structures that could affect excavation or lifting.
Assess the ground for uneven areas, soft or disturbed soil, standing water, slopes, and signs of erosion. Where ground capacity or stability is uncertain, request an appropriate site investigation or professional assessment before choosing a foundation. Photos and measurements can help your supplier and local contractor discuss constraints, but they do not replace a technical survey.
Set out the proposed building footprint using the supplier’s confirmed dimensions and the project drawings. Allow for doors, stairs, ramps, service connections, maintenance access, and any required separation from boundaries or other buildings. Check that the planned foundation positions align with the unit’s designated support points; do not assume that the floor can safely bear on arbitrary locations.
Foundation options may include concrete pads, strip foundations, a slab, or other engineered supports. The appropriate choice depends on factors such as soil conditions, unit configuration, loads, local frost or flood conditions, and intended occupancy. Have the foundation design confirmed by a qualified professional familiar with local requirements and the supplier’s support-point information.
Plan how rainwater will move around and away from the building, while avoiding discharge onto neighboring property or into unsuitable areas. As an illustrative layout reference, a fall of 1:100 is equivalent to 10 mm per metre; it is not a universal drainage specification. A site professional should determine suitable grading and drainage based on local conditions, accessibility needs, and applicable rules.
Remove unsuitable surface material only as directed by the project design, and prepare the working area so it remains stable during delivery and installation. If the site is exposed to heavy rain or temporary construction traffic, discuss whether temporary drainage, ground protection, or a different installation schedule is needed. Do not cover drainage features or service access points with the foundation or finished landscaping.

Map the delivery route from the public road to the installation position. Check gate openings, turning space, overhead clearance, road or bridge restrictions, ground firmness, and any obstacles that could prevent the transport vehicle or lifting equipment from reaching the site. Measure the narrowest points and share photographs with the supplier or logistics provider.
Confirm the unloading method, required equipment, and work area before dispatch. The lifting plan should account for the actual unit, lifting points, equipment capacity, ground conditions, and the space needed to position equipment safely. Keep people, vehicles, and stored materials clear of the planned work zone in accordance with the lift plan and site safety procedures.
Plan electrical, water, wastewater, communications, and other required services before foundations or access routes are completed. Confirm the connection locations and entry points against the unit drawings, and have utility work completed or prepared by appropriately qualified local trades. Where services will be buried, coordinate their routes and protection before backfilling.
Before delivery, check that the foundation is complete, accessible, and ready for installation; the route is clear; and the project team has the latest drawings and installation information. Verify key dimensions and levels with the contractor responsible for the work. If weather, ground conditions, or site access have changed, reassess whether delivery or lifting should proceed.
| Area | What to Confirm |
|---|---|
| Approvals | Local permits, land-use conditions, boundaries, and service constraints |
| Ground | Stability, levels, drainage, and need for professional ground assessment |
| Foundation | Design, support locations, finished levels, and compatibility with the unit drawings |
| Access | Route dimensions, turning space, overhead clearance, and equipment working area |
| Utilities | Connection points, routes, installation responsibility, and inspection requirements |
| Delivery | Transport timing, unloading method, lifting plan, and site readiness |
Keep one coordinated package of current information: site plan, measured access route, ground photographs, utility locations, local constraints, and supplier drawings. Share it with the supplier, contractor, and logistics provider so each party can identify questions before work begins. Record who is responsible for permits, foundations, service connections, unloading, and final inspections.
For procurement, provide the supplier with the intended use, site location, quantity, preferred layout, delivery constraints, and any known ground or utility issues. This helps the supplier assess whether the proposed unit and delivery approach fit the project scope. If the information is incomplete, identify assumptions clearly and resolve them before confirming production or transport arrangements.
At Hongshun Guangju, we can discuss container house configuration, project dimensions, product drawings, and installation-related information available for the selected solution. Our team can help clarify the product details your contractor may need when reviewing foundations, access, and utility coordination. Site engineering, permits, and local construction work should be confirmed with qualified professionals in the project’s jurisdiction.
When you contact us, share your intended application, approximate quantity, location, target dimensions, and any site drawings or access photographs you have. We can review the product-side requirements and help identify information to confirm before quotation and delivery planning. This early coordination can make it easier for your project team to plan the right next steps.
A container house site is ready only when the unit requirements, ground conditions, foundation design, drainage, delivery access, lifting arrangements, utilities, and local approvals have been coordinated. Start with confirmed product drawings, assess the site, and have project-specific foundations and drainage reviewed by qualified local professionals. Then verify access and responsibilities with your supplier and installation team before dispatch. To discuss a project with Hongshun Guangju, prepare your basic site information and unit requirements so we can help you review the product details relevant to planning.
