Through the approval a $20.75-million contract for URS Corp. of Dallas to begin the preliminary design work for the renovation of Terminals A, B, C and E, which opened with the Airport in 1974, DFW International Airport’s Board of Directors began an eight-year renovation process.

The final costs of the DFW Terminal Development Program are still in review, but initial estimates place the cost somewhere between $1.5 billion and $2 billion, with funding to come from bond sales, available capital and other sources.

The renovation project includes facelifts for passenger areas including ticketing, security and concessions. Plans also call for the replacement of terminal systems such as electrical, plumbing, heating and cooling, security, conveyance and telecommunications.

Current plans call for construction to begin in early 2011. Terminal A will be the first terminal completed, in 2014, and the entire project should be complete by the end of 2017. The construction phase requires one-third of each terminal to be shut down at a time.

Design concepts call for the consolidation of concessions areas into villages reminiscent of DFW’s International Terminal D, which opened in 2005 at a cost of $1.2 billion.
