Fire sprinkler systems in Jumeirah Lakes Towers (JLT) 

Fire sprinkler systems in Jumeirah Lakes Towers (JLT): local context

Jumeirah Lakes Towers is a DMCC free-zone district of around 80 towers arranged in clusters around artificial lakes, opposite Dubai Marina along Sheikh Zayed Road. Built mostly in the late 2000s, it mixes office, residential and hotel towers with ground-level retail and clinics. Manolia completed the MEP works for the Armada hotel tower (G+50) and MEP for the Armada surgical centre here.

• Construction and modification approvals run through DMCC's building authority channel rather than Dubai Municipality, with Civil Defence review of fire and life safety drawings; the exact steps depend on the cluster and works.
• Healthcare fit-outs, such as surgical centres, need dedicated fresh-air AHUs, pressure cascades between clean and dirty areas, medical gas coordination and essential power arrangements.
• Clusters share podiums and access roads, so loading bays, hoist time and crane positions are negotiated with neighbouring towers and cluster management.

Building types we serve in Jumeirah Lakes Towers (JLT)

For high-rise towers, the work concentrates on pressure-zoned water and drainage stacks, riser and plant-room coordination, stair pressurisation and a cooling source sized for diversity across dozens of typical floors.

Scope of work

• Review of the consultant's fire strategy and hazard classification for each occupancy, then hydraulic calculations confirming pump duty, pipe sizing and the most remote design area.
• Preparation of sprinkler shop drawings showing head layout against reflected ceiling plans, beams, bulkheads, diffusers and light fittings, submitted for consultant and Civil Defence review.
• Supply and installation of fire pump sets (electric duty, diesel standby and jockey pump), controllers, suction and delivery headers, test lines and flow-measuring arrangements.
• Installation of risers, floor control valve assemblies with flow and tamper switches, drain and test stations, and zone isolation so floors can be serviced without shutting the building.

Systems we install

• Dry-pipe or pre-action systems for unconditioned car parks, loading docks or areas where water damage is critical.
• Pressure-reducing valve stations for high-rise pressure zoning on tall risers.

UAE site and climate challenges

• Fire water tanks on roofs and in exposed pump rooms can reach high temperatures in summer, encouraging bacterial growth and corrosion. We specify insulated or shaded tanks, coated internals and ventilated pump rooms so stored water and diesel engines stay within manufacturer limits.
• Diesel fire pumps lose output in high ambient air and hot plant rooms. We check engine derating against summer room conditions near 46–50°C and size ventilation and radiator airflow so the pump still meets its rated duty when the room is hottest.
• Grooved versus threaded pipework: grooved systems install faster and simplify future modification, while threaded small-bore branches suit tight ceiling voids; most projects use a combination by pipe size.
