Warehouse Design in Hamriyah Free Zone (HFZA)

HFZA's building permit process is fully administered through the Hamriyah Free Zone Authority's own engineering and permits department, bypassing Sharjah Municipality's standard Basher platform. Warehouse construction applications are submitted to HFZA's technical review team, which assesses structural, MEP, and fire system drawings against HFZA's published building code and international standards. The free zone authority also coordinates civil defence compliance through its internal safety department before any building permit is issued. SEWA (هيئة الشارقة للكهرباء والماء) provides electricity and water to HFZA's landside precincts from its Hamriyah sub-district infrastructure, with power supply available at LV 400V for standard warehouses and 11kV HV for heavy industrial consumers. The Hamriyah port-side quay areas operate under separate infrastructure arrangements coordinated with HFZA's port operations.

The engineering challenges in HFZA are shaped by its coastal northern Sharjah location on reclaimed and compacted land adjacent to the Arabian Gulf. Ground investigation across different HFZA precincts reveals variability in founding conditions — from competent calcarenite/sandstone in older precincts to loose hydraulic fill in newer reclaimed areas — requiring project-specific geotechnical investigation before foundation system selection. Chemical industry tenants in HFZA drive bunded containment slab design with impermeable lining systems to meet UAE environment agency requirements for secondary containment. Heavy fabrication workshop buildings require crane girder design for 20–50 tonne EOT (electric overhead travelling) crane loads, with significant implications for column and foundation sizing.

HFZA's on-site fire brigade and emergency response team provides a higher baseline fire safety infrastructure than most UAE industrial zones, enabling a design fire engineering approach that justifies extended travel distances and reduced sprinkler density in some warehouse configurations through performance-based fire safety assessment. This approach requires a formal Fire Engineering Report prepared by a UAE Civil Defence-registered fire safety consultant and accepted by HFZA's safety department before permit issuance. Bulk liquid storage tanks adjacent to covered warehouses in HFZA must comply with API 650 welded steel tank design standards with secondary containment bunded areas calculated to hold 110 percent of the largest tank capacity plus a 24-hour rainfall volume calculated from Hamriyah's local intensity-duration-frequency rainfall data. Berth-side warehouses at HFZA's industrial quay use chemical-resistant polymer concrete channel drain systems rated for concentrated sulphuric acid and sodium hydroxide splash, connected to dedicated trade effluent treatment systems before discharge to HFZA's central wastewater network. Overhead travelling cranes in HFZA fabrication facilities are commissioned under Lifting Operations and Lifting Equipment Regulations (LOLER) equivalent UAE Standards, with safe working load (SWL) test certificates issued by an approved third-party inspection authority before handover to the tenant.
