Emphasis on constructability rehabilitates precast concrete bridge quickly

On January 21, 2011, a fatal accident involving an 8200-gal. gaso- line tanker badly damaged the Beachline Expressway/SR 528 overpass at Courtenay Parkway/SR 3 in Brevard County, Fla. Re- storing the bridge to service required only 22 days, thanks to close cooperation and a focus on constructability.
Florida Department of Transportation (FDOT) officials concluded that the two easternmost of three spans on each of the side-by-side bridges were beyond repair. Because the overpass provides critical access to the Kennedy Space Center and nearby towns, the bridge had to reopen quickly.
Within 24 hours, FDOT summoned three contractors to a prebid conference at the site. The FDOT emergency-response team de- veloped the project’s scope, acquired the original plans, and es- tablished a maintenance-of-traffic plan. The job was awarded to Lane Construction Corporation in Maitland, Fla., with a bid of $2,191,000 and a schedule of 25 days.
“The ability to meet our schedule was the most important factor in our selection of subconsultants and suppliers,” said Gary F. Jera- bek, district manager for Lane Construction Corporation. FinLEy Engineering Group in Orlando was selected to design the repair and reconstruction work.
FinLEy submitted the initial precast, prestressed concrete AAS- HTO i-beam design to Lane within 12 hours after receiving the contract. The first beam was cast within 24 hours of the notice to proceed by Standard Concrete Products, Tampa, Fla. Final beam designs were complete within 36 hours. Read more…
