تصميم المستودعات في JAFZA — Jebel Ali Free Zone

Warehouse construction within JAFZA is governed by a two-tier permit process. JAFZA's own Engineering and Projects division reviews all building applications, including structural drawings, MEP coordinated drawings, and fire protection layouts, before issuing the zone-level NOC. A separate Civil Defence NOC from the Dubai Civil Defence and Fire and Rescue Authority (DCDFIRA) is mandatory for fire suppression and life safety system approvals, required before JAFZA will issue the building completion certificate. Structural permit submissions to JAFZA must follow the zone's published technical guidelines, which specify minimum plot coverage ratios, maximum building height (typically 30 metres for standard warehouse clusters), mandatory setback distances from zone roads, and dock leveller bay count requirements relative to GFA. Warehouse occupiers in JAFZA must hold a JAFZA trade licence, and the permit process is linked to the company's registered activity scope — a logistical step that experienced consultants co-ordinate with JAFZA's company registration team from the outset.

Structural engineering demands in JAFZA are driven by the logistics sector's appetite for high-bay racking systems. Clear internal heights of 12–18 metres are common for modern distribution centres, with some hyperscale fulfilment facilities reaching 24 metres to accommodate very narrow aisle (VNA) automated storage and retrieval systems (ASRS). Such heights require heavy-gauge portal frame sections — typically 600–800 mm deep fabricated plate girder rafters at 6–7.5 metre frame spacing — with moment-resisting base plates and heavy anchor bolt groups cast into reinforced pile caps. Concrete floor slab design for high-bay racking must achieve TR34 FM2 or FM1 flatness tolerances (Defined Floor Flatness tolerances Ff ≥ 50, Fl ≥ 30 for FM1), requiring laser-screeded superflat finishes placed in narrow bay strips with controlled saw-cut jointing to manage shrinkage. Subsoil beneath JAFZA is predominantly sandy hydraulic fill placed over dredged marine sediment during the port and zone reclamation programme; pile foundations — driven precast or bored cast-in-place — are near-universal for warehouse structures, with design working loads governed by site-specific geotechnical investigation reports.

MEP infrastructure in JAFZA warehouses reflects the zone's heavy logistical demand. DEWA (Dubai Electricity and Water Authority) supplies electricity to JAFZA, with large warehouse facilities — above approximately 5,000 kVA connected load — served by high-voltage 11 kV supply from DEWA's JAFZA zone substation network, requiring a tenant-owned primary substation room within the building. Dock levellers, powered roller conveyor systems, and automated dock management equipment create peak electrical demand profiles that must be carefully modelled in the load schedule to avoid over-sizing the DEWA supply application. Fire suppression design in JAFZA warehouses follows NFPA 13 for in-rack and overhead sprinkler systems, with commodity classification and racking configuration driving remote area calculations. DCDFIRA's approval of fire suppression shop drawings is required before installation begins, and DCDFIRA's final inspection certificate is a mandatory prerequisite for JAFZA's building completion sign-off. Emergency generator provisions and UPS systems are standard for logistics control rooms and dock management offices, sized to maintain refrigeration continuity in temperature-controlled sections serving pharmaceutical cold chain or food distribution tenants. Customs-bonded warehouses in JAFZA must incorporate Federal Customs Authority-compliant perimeter fencing, CCTV coverage, and secure access control — requirements that affect the building envelope design, site boundary wall specification, and MEP infrastructure budget from the earliest design stages.
