Prefab and folding-house project by PT KWD

Modular design and rapid deployment

Custom dimensions, layouts and envelopes

For offices, accommodation and project camps

Specifications

Modules, structure and envelope configured for the use

A prefab building is a complete system. Final dimensions, loads, fire performance and insulation must be confirmed for the location, use, logistics and local approvals.

Parameter	Common range / note
Envelope thickness	Common sandwich panels 50–100 mm; selected for insulation and fire requirements
Module width	Commonly approx. 2.4–3.0 m; adjustable for layout and transport
Module length	Commonly approx. 5.8–6.0 m; combined length developed for the plan
Primary material	Structural steel or cold-formed steel frame with color steel sandwich-panel envelope
Surface finish	Anti-corrosion primer and topcoat; hot-dip galvanizing optional for the environment
Color range	Wall, roof and trim colors confirmed against color cards and material MOQ
Design references	Structural checks may use SNI 1727:2020, SNI 1729:2020, SNI 7971:2013 and local seismic requirements. This is not a certification claim for an unconfirmed project

Production

From module detailing to pre-assembly inspection

Primary structure and envelope components are prepared in the factory to reduce wet work and improve installation control on site.

01
**Brief and layout**
Confirm occupants, functions, doors, windows, services and logistics.

02
**Component fabrication**
Frames, connectors and panels are produced from coordinated drawings.

03
**Module pre-assembly**
Dimensions, interfaces, openings and key trim details are checked.

04
**Packing and dispatch**
Packing follows the intended unloading and lifting sequence.

Installation

Foundations, connections and waterproofing shape long-term performance

Site installation must follow structural design, the lifting plan and local safety rules. Building services and fire systems require coordination by the relevant specialists.

01
Verify foundation levels, anchors, drainage falls and the lifting area.
02
Place numbered modules and complete structural, floor and roof connections.
03
Seal panel joints, roofing, openings and penetrations against water ingress.
04
Complete electrical, plumbing, fire, grounding and pre-handover checks.
