Denver International Airport South Terminal Redevelopment, United States of America

Denver International Airport South Terminal Redevelopment

Denver International Airport's (DIA) South Terminal Redevelopment Program (STRP) launched in October 2011 to increase the overall passenger and aircraft handling capacity T the airport.

"DIA is the world's 10th busiest airport, handling 53.2 million passengers in 2012."

The $544m project includes the construction of a new Westin Hotel and conference centre, a Public Transit Centre (PTC) and a Public Plaza at the terminal. It is expected to be finished by 2015.

The project will create 1,000 jobs, including 700 in construction and design, and 200 permanent jobs in the hotel.

DIA is the world's 10th busiest airport, handling 53.2 million passengers in 2012. The airport is owned and operated by City & County of Denver Department of Aviation.

History of the South Terminal Redevelopment Program at DIA

The STRP project was first designed by Santiago Calatrava. The original design included the plan to construct a signature bridge over Peña Boulevard for a FasTracks commuter train.

The Regional Transportation District (RTD) identified, during an inspection in April 2011, that the construction of an elevated rail line would be cheaper than that of a signature bridge. The estimated cost for the signature bridge was $22m while the rail line will cost just about $1.4m.

The design concepts for the STRP project were revised accordingly in January 2012. The revised plan includes the construction of an elevated rail line over Peña Boulevard and a reduction in the size of the train station and hotel at the terminal, while reducing the project's original cost from $650m to $544m.

Details of the DIA South Terminal Redevelopment Program

The terminal design will be based on LEED (Leadership in Energy and Environmental Design) standards.

The 433,000ft² Westin hotel will have 14 floors and 519 guest rooms. It will feature a grand lobby, which will provide views of the mountains and runways at the airport. It will also feature a restaurant, gym, a fitness centre and an indoor pool.

The saddle at the centre of the hotel is designed to maintain sight lines to the terminal's signature peaked roof.

The conference centre will cover an area of 10,000ft² and have 12 meeting rooms. It will be used for meetings, banquets, conventions and trade shows. An area of 16,000ft² will be covered by three ballrooms.

An escalator will be installed in the centre of the Plaza to facilitate passenger movement to four levels, from the PTC level to the main floor of the Jeppesen Terminal.

The existing concourse baggage and train systems will be also improved as part of the project.
