A modular integrated construction house does not have one fixed price per square metre. Modules are produced in a controlled factory, transported to the project site and installed on a permanent foundation. The quotation therefore depends on both the building itself and the work required to deliver, lift, connect and complete it. Prices advertised for basic container units, light-steel rural houses and high-standard concrete modular integrated construction buildings should not be compared without checking the same scope of supply.
Cost Factor | How It Affects the Quotation |
Size and layout | Larger floor area increases material and production volume. Multiple storeys, cantilevers, irregular plans and fewer repeated modules add engineering and fabrication work. |
Structure and materials | Steel or concrete module type, design loads, insulation, fire protection, facade, windows, roofing and corrosion protection determine the base manufacturing cost. |
Interior specification | Bathrooms, kitchens, MEP systems, doors, flooring and premium finishes can substantially change the factory-completion level and final price. |
Location and logistics | Factory-to-site distance, road restrictions, module dimensions, permits, sea freight, cranes and installation access affect delivery and lifting costs. |
Site and foundation | Land clearing, grading, drainage, soil conditions and the selected slab, crawl space, piles or basement are normally project-specific. |
Utilities and approvals | Water, electricity, sewage, local engineering, permits, inspections and code compliance may be included separately from the module supply. |
Scale and repetition | A larger project with repeated module types generally improves factory efficiency and can reduce the unit cost compared with a one-off custom house. |
Cost Package | Typical Scope |
Design and engineering | Architectural coordination, structural calculations, module splitting, shop drawings, MEP coordination and approval revisions. |
Factory production | Steel or concrete structure, floors, walls, roof build-up, insulation, doors, windows, finishes, MEP installation, testing and factory quality control. |
Logistics | Protective packaging, inland transport, oversized-load permits, port handling, sea freight, insurance and temporary storage where required. |
Site installation | Crane mobilisation, lifting plans, module positioning, structural connections, weather sealing, MEP connections and finishing of module joints. |
External works | Foundations, drainage, roads, landscaping, utility networks and site-built elements outside the module supply. |
A modular integrated construction module must remain stable not only in service but also during factory handling, road or sea transport and crane lifting. This can require temporary bracing, stronger lifting points, additional structural members and carefully detailed connections. High factory completion also moves bathrooms, kitchens, finishes and building services into an earlier stage of the cash flow. These items can make the initial module package appear more expensive than a basic conventional structural frame.
The correct comparison is the completed building on the same site and to the same specification. A low module price may exclude foundations, transport, cranes, utility connections, permits, local taxes and commissioning. A conventional construction estimate may also omit programme costs, financing, site supervision, weather delays or rework. Comparing only one square-metre figure can therefore produce a misleading result.
Factory production can run in parallel with site preparation, reducing the overall project programme. Repeated module types improve material planning, labour productivity and quality control. Less wet work may reduce site labour, temporary facilities and weather exposure. Earlier completion can also bring forward rental income or building use. These benefits are project-specific, but they explain why lifecycle value may be stronger than the initial purchase price suggests.
Operating cost also depends on the envelope and services specification. Continuous insulation, controlled air leakage, efficient HVAC and factory-tested plumbing or electrical systems can reduce energy use and later repair work. These savings should be assessed through actual thermal calculations, equipment selections and maintenance plans rather than assumed from the word “modular” alone.
Item to Confirm | Quotation Question |
Foundation | Is the foundation design and construction included, and who is responsible for geotechnical information? |
Delivery | Does the price include inland transport, sea freight, permits, insurance and unloading at the final site? |
Crane and access | Who supplies the crane, lifting plan, temporary road, working platform and traffic control? |
Utilities | Where is the supply boundary for water, power, sewage, data, HVAC and fire protection connections? |
Approvals | Are local design adaptation, permits, inspections, testing and certification included? |
Finishes and commissioning | Which interior finishes, appliances, final sealing, testing, cleaning and handover activities are included? |
A useful request for quotation should include the site address and nearest port, intended building use, total floor area, number of storeys, architectural plans, target module dimensions, design wind and seismic criteria, occupancy loads, fire requirements, thermal standard, interior finish schedule, MEP scope, delivery date and installation responsibility. Photographs or a logistics survey are helpful where access is restricted.
ZSJH can review this information and organise the proposal into clear commercial packages, such as structural module supply, factory-finished modules, delivered-to-port supply or a broader delivery-and-installation scope. Stating the inclusions, exclusions and technical assumptions makes competing quotations easier to compare and reduces the risk of unexpected site costs.
