Confirm the system before comparing prices
The term flat-pack can describe a compressed set of roof and floor cassettes with wall panels, or a more completely demountable kit. Ask exactly how the columns, frames, panels and services arrive and which operations must be completed on site.
- What are the external module dimensions?
- Is the frame bolted, welded or a combination?
- How many storeys is the quoted system designed for?
Check the engineering basis
A standard module still needs project-specific verification. The supplier should identify the design loads, steel grade, coating system, floor load and structural documentation that form the quotation.
- Which wind, snow and seismic values are assumed?
- Which structural standard will be used?
- Are calculations and connection drawings included?
Define the complete supply scope
Frames and sandwich panels are not a complete building. Clarify doors, windows, floor finish, flashings, gutters, sealants, fasteners, electrical items, plumbing, sanitary fixtures, HVAC provisions and spare materials.
- Are all joining accessories and weather seals included?
- Which electrical voltage and socket standard are supplied?
- Are bathrooms or kitchens factory prepared or site installed?
Verify packing and logistics
Loading capacity changes with panel thickness, bathroom content, loose accessories and protective packing. Request a preliminary packing concept before relying on a freight budget.
- How many sets are expected per 40-foot high-cube container?
- Will every package be marked by module and installation sequence?
- Who prepares the packing list and export documentation?
Plan site assembly and handover
The buyer should know the foundation tolerance, crane requirement, storage area, crew size and weather-protection method before dispatch. Installation manuals must match the delivered system rather than show a generic product.
- Is an installation supervisor available?
- What must the local team prepare before arrival?
- Which inspections and handover documents are included?
