Concrete mix failures force re-pours; FAA rejects defective panels, extending project timeline
Summary
Contractor mix issues have led to removal and replacement of multiple concrete panels on the apron; the FAA and airport QA have required rework at contractor expense and staff estimate concrete will need standard cure periods before reopening.
Staff reported repeated failures in concrete panels on the apron project after pours produced cracks and did not meet specified flexural strength. The contractor has removed and re-poured panels multiple times; staff and FAA inspectors have refused to accept failing panels and the cost of removal rests with the contractor.
"The concrete panels continue to fail... The FAA won't accept it. I won't accept it. So they have to tear it out," the director said. A construction presenter added the specification calls for 14 days after paving before opening unless flexural-strength tests allow earlier use; the full 28-day strength curve remains part of the quality program.
Board members and staff said crews are pouring in multiple night shifts to complete the remaining concrete work; the airport QA manager and an independent third-party testing firm oversee acceptance and the airport has the final say on pass/fail for panels. Staff emphasized that repeated rework increases schedule risk but noted contractor bears removal costs.
