CO Airport Project Delayed Over Concrete Issue


Work at the Denver International Airport is facing what could be a 10-month delay after finding that the concrete in the main floor is weaker than expected.

The extent of the delay and the severity of the problem, however, won’t be known until at least April, according to spokesperson Stacey Stegman, the Denver Post reports.

The Project

The concrete issue was found in the $650 million Great Hall part of the project, one that totals an estimated cost of $1.5 billion that is headed by private partner Ferrovial Airports.

Work is being overseen by Saunders Construction, with the expansion originally slated for completion in 2021. Overall, this project is part of a $1.8 billion deal for the Jeppesen Terminal that was struck last year with Great Hall Partners.

For the airport’s expansion, DIA officials are looking to expand the current traveler capacity—which stands at 50 million annually—to 80 million. In 2016 alone, 53.8 million travelers passed through the DIA.

Currently, the DIA has 107 regular gates and 42 “apron load” positions, according to the Post. The apron load area allows passengers to board smaller planes on the tarmac. The proposed expansion would increase the total of regular gates by 36 percent.

The airport currently serves United, Southwest and Frontier, along with smaller airlines.

In January 2018, Turner Construction and Flatiron Construction were announced as the companies that would be building two new hubs for the airport, with the capacity for three more, as well as 16 new gates and installing additional pavement. Concourse A will expand by 530,000 square feet, and Concourse B will see the addition of 91,000 square feet.

The project is still in Phase No. 1, which was originally slated to run to the summer. In this phase, the plan was for workers to tear down walls and extend the “floor plate” of the upper level by about 30 feet into the atrium. Baggage offices on Level 5 are also set to be redone.

What Happened

Officials said that early testing of the concrete’s compressive strength was lower than what the project’s plan specified, so the area began undergoing intensive testing, which is now underway. The DIA notes that the testing needs to be done before cranes can be brought onto the main floor and begin erecting steel.

The preliminary estimate says that the project could be delayed by 209 work days—roughly 10 months total.

“The projected schedule represents their estimates but does not include the airport’s review and analysis or ways to mitigate” the problem, said Stegman.

“The issue cannot be fully known or realized until April when the testing is completed and the airport is able to review and analyze the results with Great Hall Partners.”
