Volumetric Modular Units

Best-fit project conditions

Repeatable hospitality or accommodation rooms
Projects where reducing on-site fit-out is important
Sites with verified routes, crane access and suitable module geometry

Basic form

Three-dimensional modules are manufactured and may be substantially fitted out before transport. Modules are delivered, lifted onto prepared foundations or supporting structures, connected and completed at their interfaces.

Design inputs

Module grid, room repetition and transport envelope
Site-specific structural and stability requirements
Fire and acoustic compartment interfaces
Envelope continuity and inter-module weather seals
MEP connection strategy and commissioning
Route survey, lifting plan, foundations and tolerances

Factory and site work split

Area	Possible factory scope	Site scope and interface
Module structure	Three-dimensional frames and internal assemblies may be produced in controlled conditions.	Modules are set, connected and tied into the project structure.
Interiors	A higher level of lining, fixtures and finishes may be possible.	Interfaces, damage repair and final completion remain.
MEP	In-module services can be installed and tested to an agreed point.	Risers, mains, utilities, connections and commissioning are coordinated locally.
Envelope	Module faces may be substantially complete.	Joints, interfaces and external continuity require site completion and verification.

Scope and responsibility

China supply coordination

Coordinate the selected system, supplier information, quality planning, export packing and agreed delivery support.

Locally licensed professionals

Confirm project criteria, adapt and verify design, interpret local requirements and provide required professional sign-off.

Local contractor

Control foundations, access, safety, temporary works, unloading, assembly, services, testing and local workmanship.

Owner

Provide the brief, site rights and information, appointments, approvals, decisions, funding and project governance.

Engineering documents

Module and interface design criteria
Transport and lifting information
Foundation, support and tolerance interfaces
Inter-module structural, fire, acoustic and weather details
MEP connection and commissioning schedule
Module inspection and handover records

Quality-control planning

Frame geometry and accumulated tolerances
Concealed services and pre-close inspections
Finish protection and defect recording
Functional testing before dispatch where included
Transport bracing and release checks

Packing and logistics

Module dimensions and legal route limits
Route survey and transport permits
Weather and finish protection
Lifting points, spreaders and crane planning
Delivery sequence with minimal site storage

Installation interfaces

Verified foundations and survey controls
Crane and exclusion-zone planning
Temporary and permanent connection sequence
Inter-module sealing and fire/acoustic continuity
MEP connection, testing and commissioning

Main limitations

Lower transport density than panels or kits
Route and crane constraints can govern module size
Late changes can affect completed interiors and services
Accumulated tolerances need close control
Factory completion does not remove local permits, inspections or contractor duties

Procurement questions

What percentage and scope of finish is actually completed?
What route and lifting assumptions set module size?
How are inter-module fire, acoustic and weather interfaces verified?
Who owns transport damage risk at each handover point?
How are foundations and module tolerances coordinated?
Which tests are repeated after site connection?
