Allegheny County Airport Authority (ACAA) has selected Gensler and HDR to design a landside terminal as part of the $1.1bn Pittsburgh Airport modernisation programme in the US.

Gensler and HDR have signed a joint venture (JV) agreement to design and deliver the terminal Pittsburgh Airport modernisation programme.

The JV will work in cooperation with Luis Vidal + Architects of Spain to consolidate check-in, ticketing, security, and baggage operations into a single facility. HDR will oversee the design’s engineering implementation.

Under the $15m design contract, the team is expected to submit a preliminary design by early next year.

ACAA CEO Christina Cassotis said: “We are confident that we have assembled a world-class team with the vision, knowledge and experience necessary to work with all of our partners in building Pittsburgh’s airport: an airport that will transform the travel experience now and into the future and continue advancing our region.

“Under the $15m design contract, the team is expected to submit a preliminary design by early next year.”

“Our selection team has carefully researched best airport design and modernisation practices and worked to review qualifications of the firms, their proposals and references.”

From a group of 11 firms, the companies were selected based on their experience, team composition and responsibilities, design and management approach, quality assurance and cost control, and DBE/local participation.

Gensler has offices in 46 cities worldwide, designed the 32-storey Tower at PNC Plaza in Downtown Pittsburgh, as well as Incheon International Airport in Korea.

HDR’s design works included modernisation of the Honolulu International Airport, and locally, the Greenfield Bridge replacement project.

Luis Vidal + Architects is currently working at the international airports of Denver, Boston Logan, and Dallas Fort Worth. The company has offices across Spain, the UK, Dominican Republic, Chile, and the US.

Construction work under the Pittsburgh Airport modernisation programme is expected to begin next year, with the new terminal set to open in 2023.
