Testing showing weaker-than-expected concrete in the main floor of Denver International Airport’s terminal has slowed construction on a massive renovation project and could delay completion by up to 10 months, according to a new report produced by the contracting team.
The extent of the delay — and the severity of problems with the 25-year-old structure’s original concrete — won’t be known until at least April, DIA spokesperson Stacey Stegman said. That’s when intensive testing of the concrete that is now underway is expected to be complete.
DIA expects that testing will shed light on the concrete’s load-bearing ability before contractors bring cranes onto the main floor of the terminal and begin erecting steel.
But a preliminary estimate by Great Hall Partners, the private consortium carrying out the $650 million renovation project, is that the concrete issues could delay the project by 209 work days.
That would equate to roughly 300 days when weekends and holidays are added in — or nearly 10 months beyond late 2021, the original target for completion.
