Southwest Airlines Maintenance Expansion

As a mechanical and plumbing engineering firm on Jacobs Denver International Airport (DEN) on-call A/E design team, 360 Engineering has completed several projects at DEN. For the expansion of Southwest Airlines maintenance storage area in Concourse C, the firm provided mechanical, plumbing, and fire protection engineering for the buildout of 16,400 square feet of space. The space included offices, conference room, break room, locker/shower rooms, a tool box storage area, an oxygen room (with dedicated exhaust system), and a 6,000 square foot material storage/staging area.

360 Engineering’s involvement began with initial site planning and coordination to observe existing mechanical, plumbing and fire projection systems. During the design phase, existing mechanical and plumbing systems were modified to support the remodeled areas. The design challenge during this project was trying to provide full capabilities for the space while dealing with limitations of the existing systems at DEN. Existing hydronics were approaching capacity and the team was tasked with providing outside air for Southwest’s parts/storage area where forklifts operated.

For fire protection, performance specifications were provided for the design/build fire protection contractor to use. Finally, construction administration services were provided including the review of submittals, answering any RFI’s, OAC meetings, and final punch walk with report.
