Lincoln Square – Expansion Phase 2
Bellevue, WA / 1,500,000 SF
The new 1.5 million square feet, mixed-use development in the heart of downtown Bellevue will provide visitors Class A offices, including 6 floors of well-designed underground parking, luxury residences, new hotel, upscale retail-driven restaurants and 16 cinemas. The central plant consists of (4) 750-ton centrifugal water chillers that are interconnected with the 3,000-ton cooling tower located at the top of the office tower structure. These systems are connected via 18” carbon steel condenser water piping with (2) 100 horsepower pumps moving thousands of gallons of condenser water several hundred feet between these massive pieces of equipment. The chilled water distributes to the podium and towers via a network of pumps and thousands of feet of carbon steel and copper piping serving a range of air handlers, fan coil units, water source heat pumps and compressor racks. This central plant provides enough cooling to serve the needs of 13 commercial kitchens and restaurants, 120,000 SF of retail and common areas, 227 hotel rooms, 220 residential apartments and over 700,000 SF of office tower space. This facility will serve the cooling needs of over 6,000 people and a total of 1.6 million SF.
The MacDonald-Miller team adeptly addressed the unique needs of a mixed-use facility, providing an innovative concept and design, purchasing millions of dollars in equipment, fabricating tons of steel pipe and supports, and engaging thousands of man-hours to install one of the largest commercial central plants in the Pacific Northwest.
