Aeronautics Manufacturing Design & Construction

Location: Marietta, Ga.

Client: Lockheed Martin Aeronautics Co.

Burns & McDonnell has completed several projects every year for Lockheed Martin Aeronautics Co. at its Marietta, Ga., plant for the past 10 years. Projects range from precision controlled paint and coating facilities for the aircraft manufactured at this plant to chilled water plant retrofits to replace chillers, create primary-secondary pumping systems, and HVAC modifications to adapt to new product and program requirements. Burns & McDonnell provides studies, inspection services, engineering services and construction services to Lockheed Martin at the Marietta plant. Examples of recent projects:

Building L-64 Coating Facility

This building was built in two phases eight years ago by Burns & McDonnell. It has three chiller plants, each dedicated to a single hangar bay. To improve energy savings, a retrofit project piped all three of the chiller plants together to form a single primary-secondary pumping system. This modification allowed for the elimination of one 500-ton chiller. The new secondary pumps were provided variable frequency drives for increased optimization of water flow.

Building L-41 Chiller Plant

This chiller plant, along with an adjoining chiller plant, serves an existing five-story office lean-to between two hangar bays used to service up to six C-5 Galaxy airlifter for maintenance or retrofitting. The chiller, cooling tower, chilled water pump and condenser water pump are being replaced with a new, high efficiency chiller, package cooling tower and new pumps. The replacement chiller is part of an existing primary-secondary pumping arrangement and must be piped in to continue the efficient energy savings and in a manner that allows for effective maintenance of the new equipment.

Building L-65

This building is a high-tech computer simulation and testing facility that is frequently modified by Burns & McDonnell for the newest technology and aircraft programs being provided for the armed forces aviation needs. This requires physical building renovations, new HVAC equipment, modified fire suppression systems, electrical systems and improvements in efficiency whenever possible. Due to the differing security clearances of each program the systems have to be tailored to their needs with sound deadening designs and security considerations not normally found in other buildings.
