Multi-Goods Storage Steel Warehouse Facility, Wattala – Pre Fabricated (32,000 SQUARE FEET)

Delivered as a full civil and structural development supporting multi-product storage operations.

Challenge

Strategically located within a key logistics corridor, this 32,000 sq.ft. warehouse required a structurally robust and highly adaptable design capable of accommodating diverse product categories and dynamic loading conditions.

Site Preparation & Earthworks

The project commenced with soil testing, excavation, and compaction works to establish a stable formation level for foundation construction.

Ground engineering included:

• Site leveling and grading
• Excavation for foundation pads
• Compacted sub-base preparation
• Underground drainage layout installation

Foundation & Substructure

The foundation system comprised reinforced concrete pad and pedestal foundations designed for heavy structural loads.

Works included:

• Precision anchor bolt cage installation
• Reinforced concrete pad foundations
• Pedestal column construction
• Structural concrete curing and strength verification
• Integration with slab reinforcement system

Industrial Flooring

The floor slab was engineered for static equipment loading and long-term durability.

The slab construction included:

• Heavy-duty steel reinforced concrete slab with C25 ready mix concrete 
• Anti-crack reinforcement detailing
• Control joints
• Surface hardener finish
• Integrated cable trench system

Structural Steel Superstructure

The superstructure was executed using a Pre-Engineered Steel Portal Frame system optimized for medium-span industrial storage.

Structural elements included:

• Tapered steel columns ( H Irons with Nut and Bolt System )
• Fabricated rafters
• Z-section roof purlins
• C-section wall girts
• Sag rods
• Cross bracing for wind resistance
• Fully bolted structural connections

Roofing & Thermal Performance

The roofing assembly was engineered for tropical heat and heavy rainfall exposure.

The roof build-up included:

• Zinc-Aluminium (Alu-Zinc) roofing sheets
• MCFOIL radiant barrier insulation system
• Z-purlin support grid
• Ridge caps with sealed weatherproof joints
• Industrial flashings at roof transitions
• Fabricated box gutters
• Eave gutters
• Downpipe rainwater discharge network

Complete construction lifecycle executed under single contract.

Cladding & Completion

The building was fully enclosed using corrosion-resistant wall cladding supported by C-girts, incorporating ventilation provisions and secure access openings.

This project clearly demonstrates full lifecycle civil and structural construction delivery.
