Project Overview
This 22,000 m² logistics hub is located in Dubai South (DWC) Free Zone, UAE. Completed in 2023, the project serves as a regional distribution center for a global logistics company. The facility required a massive clear-span warehouse with integrated office mezzanine, fire-rated construction, and design for extreme ambient temperatures (up to 50°C).
The structure features 50-meter clear-span bays (total 220m length × 100m width) with 18 meters eave height. Total steel consumption: 850 tons of Q355B and Q420B high-strength steel. The design accounts for UAE Building Code (adopted IBC 2018), Dubai Municipality requirements, and extreme temperature service conditions (50°C ambient, 70°C roof surface temperature).
All structural design was carried out in accordance with UAE Fire & Life Safety Code (2018), IBC 2018, and BS 5950. Our engineering team provided full calculations, fabrication drawings, and Dubai Municipality submission documents. The client appointed a UAE-based consulting engineer for design review and authority approval.
Project Challenges
1. Extreme Temperature Design (50°C Ambient). Dubai's summer ambient temperature reaches 50°C, with roof surface temperatures exceeding 70°C. Steel strength reduces at elevated temperatures (per BS 5950 Part 1, Table 1 — steel yield strength at 50°C: 95% of room temperature value). We upgraded all primary members to Q420B steel (420 MPa yield) to maintain adequate load capacity at design temperature.
2. 2-Hour Fire Rating Requirement. Dubai Municipality requires 2-hour fire rating for logistics warehouses >10,000 m² (UAE Fire & Life Safety Code Clause 4.2.1). We applied intumescent paint (2-hour rating per BS EN 13381-8) to all primary steel members. The mezzanine floor system used 2-hour fire-rated composite deck + concrete slab.
3. 50m Clear-Span Requirement. The client required 50m clear span bays to accommodate 40-foot container stacking (6-high) and automated guided vehicles (AGV) movement. This required careful design of the main rafters (H1200×400×20×36) with mid-span splice connections designed for both moment and shear transfer.
4. UAE Customs and Free Zone Documentation. Dubai South Free Zone has specific import documentation requirements. All steel members must be accompanied by a Certificate of Conformity (CoC) issued by an UAE-authorized inspection agency. We coordinated with SGS Dubai to perform pre-shipment inspection and issue CoC for all 68 containers.
Our Solution
Design Phase: Our engineering team developed a 3D structural model of the 220m × 100m × 18m logistics facility. The model accounted for UAE Building Code (IBC 2018 adopted) wind loads (1.5 kPa roof, 2.0 kPa walls — enhanced for Dubai's frequent dust storms), a 1.2 kN/m² roof live load, and a 6.0 kN/m² floor live load for 40-foot container stacking.
Fabrication: All H-sections were CNC-cut from Q420B steel plate (for temperature service). The fire-rated coating system: 1×125μm intumescent base coat (2-hour rating), 1×80μm polyurethane topcoat (UV-resistant, suitable for Dubai's intense sun). All bolted connections use hot-dip galvanized 10.9/S grade bolts (galvanizing prevents bolt seizing at high temperatures).
Mezzanine Office Design: The 3,000 m² mezzanine office uses composite steel deck (150mm deep) + 130mm concrete slab. The floor system provides a 3.0 kN/m² live load for office use. Fire rating: 2-hour (BS EN 13381-8). The mezzanine also includes fire-rated staircases (2-hour) and fire-rated elevator shaft (steel encased in fire-rated drywall).
HVAC-Ready Roof Structure: Dubai's logistics warehouses require massive HVAC systems. We designed the roof structure with equipment support platforms (capable of supporting 5-ton HVAC units at 15m spacing). All roof penetrations for HVAC ducting were pre-fabricated with flanged openings and curb details.
Steel Structure Design
Portal Frame Design to BS 5950 (UAE Adoption)
The portal frame was designed as a moment-resisting frame with pinned-base conditions (to simplify foundation design). Column spacing: 10 meters. The frame provides 50m clear span with 18m eave height. Q420B steel was used for all primary members to maintain adequate load capacity at 50°C design temperature (steel yield strength derating per BS 5950 Table 1).
Wind Load Analysis (UAE Building Code / IBC 2018)
Dubai's wind load calculation follows IBC 2018 (adopted by UAE). Basic wind speed: 45 m/s (150 km/h, Category 3 tropical storm equivalent). The design applied both static and dynamic wind load cases, with special attention to roof cladding suction loads during dust storms (frequent in Dubai summer).
Fire Rating Design (UAE Fire & Life Safety Code)
For 2-hour fire rating, we applied intumescent paint to all primary steel members. Intumescent paint expands when exposed to fire (200-300°C), creating a char layer that insulates the steel and maintains load capacity for 2 hours. The mezzanine floor system used 2-hour fire-rated composite deck (BS EN 13381-8 certified).
Container Stacking Load Design
The warehouse floor is designed for 6-high 40-foot container stacking (maximum 6×30.5 tons = 183 tons per stacking position). Floor live load: 6.0 kN/m² (UAE Building Code Table 1607.1). The foundation design used 2.0m × 2.0m × 1.5m deep reinforced concrete pads (40 MPa concrete) to distribute container stacking loads to the ground.
Fabrication Process
Q420B Steel Fabrication
Q420B high-strength steel requires careful welding procedure qualification (WPQ). All welds were performed using low-hydrogen electrodes (to prevent cold cracking in high-strength steel). Preheat temperature: 120-150°C (per BS EN 1011-2). All welds were 100% UT-inspected. Post-weld heat treatment (PWHT) was performed for thick plates (>40mm) to relieve residual stresses.
Fire-Rated Coating Application
Intumescent paint application requires strict environmental control: temperature 10-35°C, relative humidity <85% (per manufacturer's specification). Each coat was allowed 24-hour flash-off time. DFT: 1,200μm (intumescent base coat) + 80μm (polyurethane topcoat). Coating thickness was verified using a dry-film thickness gauge (SSPC-PA 2).
HVAC Platform Fabrication
Roof-mounted HVAC platforms were fabricated from H250×125×6×9 steel sections (Q235B, adequate for platform loads). All platforms were hot-dip galvanized after fabrication (to prevent corrosion from HVAC condensate). Platform dimensions: 2.5m × 1.5m (suitable for 5-ton HVAC units). Curb details for roof penetrations were pre-fabricated with flanged openings.
Quality Control
Laotie Steel operates an ISO 9001:2015 certified quality management system. For this Dubai project, we implemented additional QC protocols for high-temperature service and fire-rated structures.
Material Quality Control: Q420B steel plates were verified for chemical composition (spectrometer analysis) and mechanical properties (tensile test, impact test at -20°C). All mill test reports (EN 10204 3.1) were cross-referenced to finished members. Q420B welding consumables were stored in heated cabinets (to prevent moisture absorption).
Fire Rating Quality Control: Intumescent paint application was verified by an independent inspector (SGS Dubai). Coating thickness measurements: 8 points per member (minimum). Fire test certificate: The intumescent paint system was tested per BS EN 13381-8 and certified for 2-hour fire rating. All test reports were submitted to Dubai Municipality.
Dimensional Quality Control: Pre-shipment trial assembly verified that all 50m-span rafters aligned within 5mm tolerance. We used a total station (Leica TS07) to verify the alignment of all column base plates and rafter splice connections.
Packing & Shipping
For this 850-ton structure, we developed a comprehensive container loading plan. The shipment consisted of 68 × 40ft high-cube containers, sequenced to match the client's erection schedule (Phase 1: Mezzanine office, Phase 2: Warehouse main frame, Phase 3: Cladding and HVAC platforms).
Container Allocation: 18 containers for main H-sections (columns and rafters), 28 containers for secondary members, 12 containers for cladding system (Colorbond sheets suitable for UAE's UV intensity), 6 containers for mezzanine components, 4 containers for fasteners, sealants, and fire-rated consumables.
Protection: All hot-dip galvanized members were wrapped in VCI paper. HVAC platforms were pre-assembled and shipped as units (to reduce on-site assembly time). All intumescent-painted members were wrapped in protective foam (to prevent coating damage during transport).
Documentation: Each container received a detailed packing list in English and Arabic (as requested by Dubai Customs). All documents were pre-arranged: Certificate of Conformity (CoC) by SGS Dubai, UAE Customs import declaration, Dubai Municipality pre-approval certificate, and Mill Test Reports (EN 10204 3.1).
Installation Guide
Foundation Preparation
The client's local Dubai contractor poured reinforced concrete foundations per our foundation reaction report. Dubai's soil condition: sandy desert with 150-200 kPa bearing capacity. Foundation design: 2.0m × 2.0m × 1.5m deep reinforced concrete pads with M42 anchor bolts. Foundation concrete strength: Minimum 40 MPa (UAE Building Code).
Main Frame Erection
Week 1-3: Main portal frame columns and rafters for all bays. Each column base plate uses 12× M42 anchor bolts. Column verticality is adjusted using laser plumb-bob and shim packs. Rafter-to-column connections use 10.9/S friction-grip bolts. A 100T mobile crane was used for member lifting (50m span rafters require careful lifting planning).
Mezzanine Installation
Week 4-6: Mezzanine floor beam and deck installation. Composite steel deck sheets are roll-formed on-site (using our supplied roll-forming machine) to minimize joints. Concrete pouring: 130mm thickness, 40 MPa concrete (pumped from ground level).
Cladding and HVAC Platform Installation
Week 7-10: Roof and wall cladding. Week 11-12: HVAC platform installation and roof penetration sealing. All HVAC platforms were pre-assembled in the factory — on-site installation only requires bolting to pre-welded roof brackets.
Erection Speed
A 20-person erection crew achieved 800 m² per day for the main frame, and 600 m² per day for cladding. Total on-site erection time: 75 working days. The client's project manager reported that the pre-galvanized and pre-painted members saved significant on-site finishing time (estimated 30 days saved compared to site-finished structure).
