Development of a new $90 million terminal at Lafayette Regional Airport is proceeding, with new design details being unveiled this week and a key personnel decision likely to follow the week after.

Airport Director Steven Picou said the public, at the Airport Commission’s regular meeting on Wednesday, will be able to view the interior layout, including locations of concessionaires, restrooms, checkpoints and other features. More specific details will follow the selection of a “construction manager at risk,” which is a private consultant that will manage construction for a guaranteed maximum price.

Picou said a special public meeting to select the manager is planned for Nov. 15, although he added the date isn’t finalized. Picou said two joint-venture firms responded to the airport’s request for qualifications in September, but he did not want to name them ahead of the selection.

The selected firm will round out a team of consultants that includes Heery International, which is overseeing the overall project on behalf of the commission, and architecture firm RS&H.

A previous solicitation for construction manager was issued in May, but the commission withdrew it in part to ensure that state lawmakers approved capital outlay funds for the 120,000-square-foot terminal. The legislature last summer approved $13.5 million in current and future funding. Another $32.6 million will come from a temporary one-cent sales tax that was collected for eight months in 2015. Federal grants and loans will make up the remaining amount.

State law requires selection of a construction manager prior to completion of the schematic design, which amounts to 30 percent of all design work. That milestone is expected before the end of the year, according to the request for qualifications. A construction schedule will be set once the manager is in place.

Lafayette Regional Airport was the fourth busiest in Louisiana in 2016 in terms of enplanements, according to the Federal Aviation Administration, but Picou said it currently operates with the smallest square footage.

“Every other airport in the state of Louisiana that has air carrier operations has had a terminal remodel or brand new terminal. Lafayette has not,” Picou said. “It’s kind of our turn.”

Separately, the Lafayette Consolidated Government Council on Tuesday will vote on the commission’s 2018 budget, which projects $12.1 million in revenue and $7.3 million in expenses. Picou characterized it as a “no big fireworks” budget.
