Bunkhouse Manufacturing | Est. 1982 | 800+ Fleet
Engineered Accommodation for India’s Most Demanding Project Sites
JP Singhal & Company manufactures and supplies fully furnished bunkhouses and PORTA cabins built to IS 2062 standards — customised for oil & gas, renewable energy, and infrastructure projects anywhere in India.
800+ Units in Fleet | 9 Standard Sizes | Custom Dimensions Available | 40+ Years Manufacturing Experience
When industrial projects mobilise to remote locations — oil fields in Rajasthan’s Thar Desert, renewable energy installations in Gujarat’s Rann of Kutch, or drilling operations in Tripura’s forested northeast — the quality of worker accommodation directly impacts project productivity, personnel retention, and HSE compliance scores.
Singhal Group of Companies (JP Singhal & Company) has been manufacturing bunkhouses and PORTA cabins since 1982. With over 800+ fully furnished units in active fleet and decades of deployment experience across India’s most challenging terrains, we are one of India’s most experienced and asset-rich bunkhouse manufacturers and suppliers.
Our bunkhouses are not prefabricated boxes. They are engineered modular structures built to IS 2062 Grade ‘B’ structural steel standards, insulated to maintain habitability in extreme temperatures, fitted with concealed FRLS copper electrical wiring, and finished with quality interior panelling — delivering a workspace or living space that your personnel will actually want to use.
We supply bunkhouses for every accommodation category: senior management single-occupancy cabins with private bathrooms, multi-man worker bunkhouses (2, 4, 6, and 8-man), specialised facility units (kitchens, dining halls, recreation rooms, offices, dry stores with chillers, toilet blocks, and pump rooms), and site-specific custom configurations.
Every unit can be delivered fully furnished with custom MDF furniture, installed and commissioned on-site, and maintained for the duration of your project. Our fleet is available on rental or purchase basis, with transportation, installation, and post-commissioning maintenance included in our turnkey offering.
For EPC contractors, oil & gas operators, renewable energy developers, and government project agencies — Singhal Group’s bunkhouse manufacturing capability eliminates the accommodation problem entirely, letting you focus on project execution.
Bunkhouse Manufacturing — Technical Capability
Structural System
Singhal Group bunkhouses are built on a heavy-gauge welded steel framework. The base frame uses ISMB 150 or ISMC 150 sections with 3mm thick fabricated C-section cross members. Main cross members are supported by ISLC 75 and ISA 45×45×3 sub-cross members for enhanced floor load capacity. Skids (ISMB 200 or ISMB 300) are available as optional upgrades for sites requiring elevated placement.
Shell & Envelope
Exterior walls and roof use 1.6mm thick corrugated MS sheet to IS 2062 Grade ‘B’ specification. Corner pillars are 5mm thick profiled sections. All exterior sheets are zinc phosphate primed for corrosion resistance, continuously welded at top and base junctions, and sealed at all gaps to prevent moisture ingress. Self-draining roof with adequate camber ensures rainwater drainage in monsoon conditions.
Insulation System
50mm thick rock wool or glass wool insulation in all walls, with the same applied to the roof when pre-laminated particleboard is used. This thermal performance maintains internal comfort in both the extreme desert heat of Rajasthan (50°C+) and cold winter conditions without excessive air conditioning energy consumption.
Interior Finishes
Ceiling: 14mm mineral wool tiles (Armstrong/Saint Gobain/Daiken) or 9mm pre-laminated particle board. Interior walls: 12mm pre-laminated MDF or particle board (Greenlam/Bajaj/Anchor). Floor: 20mm Bison Panel cement-bonded board with 2mm thick PVC vinyl flooring (LG, Royal House, Armstrong, or Wonder). Corner sections sealed with powder-coated aluminium profiles for a finished appearance.
Electrical System
Concealed wiring for 220–240V, 50Hz, single or 3-phase AC supply. FRLS copper cables from Polycab, Finolex, KEI, or Havells. MCB distribution box and ELCB/RCCB protection. Branded accessories (Anchor, ABB, Havells, Schneider). Weatherproof external connection points.
Doors & Windows
Main entry: heavy-duty wooden flush door, externally opening with concealed closer. PPGI sheet exterior laminate, decorative interior laminate, waterproofed edge profiles, mortise lock with dual-side handles. Windows: sliding aluminium anodised or powder-coated, 4mm tinted glass, MS safety grills, PVC or SS mosquito nets.
Painting
Exterior: one coat epoxy primer + two coats high-grade polyurethane paint. Bottom frame: bitumen paint for corrosion protection. Custom colour schemes and client corporate livery available on request.
Furniture (Optional)
Custom MDF modular furniture with decorative laminates. Configurations include bunk beds, desks, wardrobes, locker systems, dining furniture, and office workstations. Toilet accessories from Cera and Hindware.
