This past January, the Lincoln Square Expansion Project brought the chilled water central plant online, which serves the entirety of the campus including a 31-story office tower, 41-story residential tower and 3-story retail podium. 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. It is a massive achievement accomplishing this task within a 3-year timespan. This immense project owes its success to the hard work and dedication of the men and women of our MacMiller team, and to that of the partners at Kemper Development Company and GLY Construction.
