Warehouse Design in Al Ghail Industrial Zone

Al Ghail is administered by RAKEZ, with building permits processed through RAKEZ's technical department. Structural and MEP drawings for warehouse construction are submitted to RAKEZ's permits team, with RAK Civil Defence conducting independent fire safety review for all buildings above a threshold size. FEWA (الهيئة الاتحادية للكهرباء والماء) supplies electricity and water to Al Ghail from its inland RAK network, with HV supply at 33kV available for the zone's large industrial consumers. The distance from coastal FEWA substations means that new connections for very large facilities (above 5 MVA) may require FEWA network planning confirmation at an early design stage to ensure grid capacity availability.

The Hajar Mountain geology that characterises Al Ghail Industrial Zone creates the UAE's most technically interesting geotechnical profile for warehouse construction. Founding conditions range from residual soils (silty sands derived from ophiolite weathering) to near-surface rock at 0.5–1.5 metres depth — meaning excavation for column bases sometimes requires rock breaking, adding programme and cost relative to coastal sandy subsoil sites. Where rock is present at shallow depth, pad foundations can achieve exceptional bearing capacity (exceeding 1,000 kN/m² on fresh ophiolite), enabling lightweight substructures for even the heaviest warehouse facilities. The dry, low-humidity climate of the mountain foothills reduces concrete carbonation risk, allowing nominal cover specifications below those required in coastal saline zones.

Al Ghail Industrial Zone's position at the Hajar Mountain foothills gives it the lowest ambient dust loading of any UAE industrial zone, benefiting air filtration system design for manufacturing warehouses: intake filter banks can be specified at coarser efficiency grades (EU4 versus EU7 required in coastal zones), reducing pressure drop, fan power, and maintenance intervals for mechanical ventilation systems. Quarry vehicle access routes from nearby RAK stone quarries pass through Al Ghail Industrial Zone's road network, requiring heavy-duty road pavement design on access roads serving plots adjacent to these routes, with pavement structural assessment using equivalent standard axle calculations for the quarry truck fleet. Seismic design in Al Ghail must address the zone's mountain proximity: peak ground acceleration values for RAK's northern zones are higher than the UAE coastal average, with importance factor 1.5 applied to warehouse buildings housing hazardous materials under the UAE Building Code seismic loading provisions. Rockfall risk assessments are required by RAKEZ for warehouse buildings sited on plots closest to the Hajar Mountain face, with RAKEZ's geo-technical advisory noting the potential for boulder displacement following extreme rainfall events in the wadi catchments above the zone. Limestone aggregate sourced from local RAK quarries is widely used in concrete mixes for Al Ghail warehouse construction, providing a cost-competitive local material with adequate aggregate impact value for structural concrete specification.
