The Crane Aerospace & Electronics facility in Lynnwood is one of our area’s more established aerospace suppliers. Auburn Mechanical was the mechanical contractor on their new 12,000-SF building to develop and test the fuel flow meters used to measure the amount of fuel an aircraft’s jet engines use. These fuel flow meters are part of the LEAP-X engines that will power the Boeing 737 MAX jets. This industrial facility had several unique components that made up the mechanical scope of work, such as a Cryogenic Chiller that was capable of cooling to -87 degrees, stainless steel jet-fuel piping capable of delivering fuel at 325 degrees, and underground, welded containment piping. This project took a high degree of care due to the unique equipment and systems, aggressive schedule, and design challenges.
This design-build project was the new construction of three residential towers, a podium, and four stories of above-ground parking. The completed project is 877,000 SF. The structure consists of post-tensioned concrete on a deep pile foundation and is a mixed-use development. The project utilizes in-slab PEX water piping, which is all pre-fabricated as is the majority (95%) of D/W/V piping. The use of the Trimble device for in-slab MEP activities rapidly expedited the layout time while 3D modeling increased MEP coordination and productivity allowing us to forecast conflicts (of all types, architectural, structural, etc.) ahead of time and design accordingly.
The Project Auburn worked on this complete renovation of the Bill & Melinda Gates Foundation’s former headquarters into 80,000 SF of biotech lab and office space. The project included lab infrastructure for levels 2 and 3 for future tenants.
Phase-1 Auburn was responsible for the complete plumbing design and full 3D MEP Coordination.
Phase-2 Construction To meet this aggressive six-month schedule, Auburn completed more than 6,000 man hours of rough-in in less than eight weeks. To accomplish this, Auburn employed the use of the Trimble MEP Robotic Total Station and prefabrication at a level that is rarely engaged. The Trimble allowed for the layout of the overhead pipe racks to be completed for level 1 in one day, with simultaneous integration into 3D spooled drawings for prefabrication. These racks carry as many as ten lab services including NG, CA, CO2, VAC, D.I., LCW, LHW, TW, & Acid W&V. The complete overhead rack system was installed in four days by a crew of three, totaling over 2,800 linear feet of pipe. General Contractor: BNBuilders
Hoa Mai Gardens is a new 111-unit, low-income-housing apartment complex in the Yesler neighborhood of Seattle. The project was for the Seattle Housing Authority, and Auburn was the design-build and full-mechanical contractor. Other features of the project include a rainwater harvesting system that provides water for the toilets and the solar-powered boilers.
The project consisted of disconnecting and removing existing equipment and refurbishing the entire building with all new equipment, fixtures, plumbing, HVAC piping, and ductwork. New equipment included energy lab rooftop air-handling units, boilers, multi-stack chillers consisting of five each, chilled water and heating water pumps, heat pumps, humidifiers, fan coil units, exhaust fans, and chilled-water ceiling panels. 3D CAD drawings were used for coordination between all trades.
This 90,000-SF hospital includes an emergency department; diagnostic imaging; three operating rooms; two gastrointestinal rooms; 25 patient beds; two labor, delivery, and recovery rooms; a cafeteria; administrative space; and an 8,000-SF cold shell for build-out of 13 future patient beds. It is the first LEED-Certified hospital in Washington State.
The project included installation of four Fanwall air-handling units and a VAV air-distribution system; a Phoenix Theris System for controlling room climate and pressurization; and two 200-ton air-cooled chillers for generating chilled water and three condensing boilers providing heat for hot water.
Auburn provided plumbing and piping for the new 45,000-SF medical office building. The three story, concrete-tilt-up building houses rooftop equipment and a VAV unit on each floor. Also included in the project was a new 105,000 SF, four-level parking structure with over 310 stalls
The rental car facility includes an extensive storm-water-drainage system that culminates into a 3-million-gallon detention vault fed by 2-16 inch stormwater mains. The facility will ultimately support offices for ten rental-car companies and 5,000 parking spaces throughout the five-story garage. In addition, the new, quick-turnaround facilities will dispense over 100,000 gallons of gasoline stored on site through 48 pumps, as well as a stainless-steel piping system designed to supply windshield washer fluid.
Auburn worked on the new construction of Seattle’s Emergency (911) Operations Center and the state’s largest fire station. Specialty installations included a vehicle-exhaust system and a cooling system for the operations center. The project received LEED Silver designation and includes a rainwater reclaim for irrigation and vehicle washing.
The Seattle Academy CUB is the home of their district’s middle school students. The structure includes a gym, commons space, administrative space, roof access, and one level of underground parking. The project is targeting LEED Gold Certification with its goal of sustainable construction.
