Energy International Corporation along with partner BLE Group, UK has been selected to design, manufacture and install a system of fire and smoke safety curtains for a 21,000m2 (226,000 Sq. Ft.). Cargo terminal, and two maintenance hangars including, what will be, the world’s largest aircraft maintenance hangar when completed later this year.
“We are proud that we were chosen to be a part of this very important project,” said Allie Bazzy, President of Energy International Corporation. “Thanks to the dedication and perseverance of our Qatar team we have demonstrated that Energy International is the company to call on when there is a need for innovative engineering solutions, no matter the size of the project.”
The cargo terminal and new maintenance hangars are part of the first phase of the construction of the New Doha International Airport (NDIA), a QAR 8.5 billion, three phase project, scheduled to be completed in 2015. The new airport will also feature two of the longest runways in the world including a 4,850 meter (15,912-foot) airstrip designed specifically to accommodate the new Airbus A380-800 superjumbo jet.
The 186,000 m2 (2,000,000 sq. ft.) main facility will be the new central maintenance hub for Qatar Airways’ International fleet. The fully-air conditioned hangar will have the capability of accommodating five A380s, three A340-600s and four A320s simultaneously.
The main structure, standing approximately 45 meters (150 feet) tall and spanning 550 meter (1,800 feet), features a column-free design, the work of world renowned architectural and design firm, Ghafari. The main floor will house heavy and light maintenance bays. A workshop building at the rear of the facility will provide specialized maintenance and automated spare parts storage.
The Energy International Qatar team will provide materials and field project construction management on the project, working with BLE Group to design a custom solution for the fire and smoke curtains.
“The column-free design posed some interesting challenges,” Said Ammar Assi, Manager of Energy International’s Qatar office. “That’s why we chose to partner with BLE Group, a leading expert in fire protection systems, to assist us in designing and executing a unique solution to fit this unique design.”
The curtains, made of treated fabric, will be mounted to the bottom of the main roof decking and secured to the roof truss supports. The system is not only designed to suppress fire and smoke, but is also specified to withstand winds of up to 130 kph (80 mph).
“What made this job challenging is the curtains had to be designed so that the facility’s HVAC ducting, electrical conduits and sprinkler feed system, among other things, could pierce through the curtains without affecting their integrity,” said Assi. “This required the development of a special process to cut the fabric and secure it firmly to the ducting and piping.”
The hangar project is just one of many NDIA projects that Energy International is currently involved in. EIC is also supplying a number of components to the new 510,000 m2 (1.6 million sq. ft.) passenger terminal including ceiling fans, pre-cast oil interceptors and a number of different types of drains.
