Louis Armstrong New Orleans International Airport Concourse D Expansion

Project Overview

As part of the airport’s nearly $357+ million Capital Improvement Program, The McDonnel Group provided construction services on several critical expansion and modernization projects including:

Concourse D Expansion
The Concourse D Expansion is an approximately 56,900 SF cast-in-place concrete and structural steel roof framed building addition. The entire new Concourse is located on the second level with the first level (or Apron) used for airline operations. The project also included the construction of a “Connector” building that connects the new Rotunda gate expansion to the existing concourse. This Connector portion provides space for future retail development.

The project scope included:

  • Addition of 6 new jet bridge gates to Concourse D, constructed of exposed structural concrete
  • All new interior finishes, carpet, resilient, and terrazzo flooring
  • A focus on passenger amenities and comfort with the addition of retail services and a large food court
  • Full integration of all communication and security systems with the airlines, FAA, TSA, and other airport-wide systems

The Concourse D Expansion was the recipient of:

  • 2012 Award of Excellence (American Concrete Institute, LA Chapter)
  • 2012 Overall Best Project Award (American Concrete Institute, LA Chapter)
  • 2011 Excellence in Construction Engineering Obelisk Award (ABC, Alabama Chapter)
Testimonial
Thank you for a job well done here at the Airport. Your team ought to be very proud for the difference they have made for our community. Thank you.

Lessons Learned

  • Roofing and Material Decking

Uplift pressures were outlined in the roofing specifications, however these pressures were calculated on the entire roofing assembly, which included the metal decking and all components installed to it (wood blocking included). Therefore, during the metal deck submittal process during preconstruction, the roof pressures must be reviewed for fastener patterns. Likewise, wood blocking attachment patterns must also be confirmed prior to installation of the new roof.

  • High Performance Coatings

If a project has in tumescent fireproofing and/or high performance paint coatings, then an epoxy-based primer will be required. The standard “”shop primer”” included in most subcontractor quotes is not compatible. It is cost beneficial to make sure the steel supplier understands this and provides a compatible epoxy primer following fabrication.

  • Epoxy Flooring

Most epoxy-based flooring systems require a concrete moisture content of less than 3 lbs. per 1000 SF. Since achieving this is nearly impossible in the environmental conditions of Southern Louisiana, a moisture blocker used. Specifications and flooring subcontractors’ scope of work must be reviewed closely to ensure that this issue is raised and resolved months in advance of the flooring installation.

  • EIFS

Any joint sealants between EIFS and “other” must be applied to the base coat and NOT the finish coat. In addition, reinforcing mesh MUST either be overlapped (typically at least 2″) OR in the case of heavy duty mesh where seams are butted, then a second thin layer is required over the butted seam. This mesh prevents the expansion joints from cracking.
