Astaldi Construction Corp. announced on March 28 that it was voluntarily defaulting on four contracts with the Florida Dept. of Transportation. Included among those was a $108.3-million contract covering the 3.5-mile-long Section 7A for the $1.6-billion Wekiva Parkway project. Astaldi’s default on that project comes nearly a year after the contractor commenced work on April 1, 2018.
