Corbett-Sugar-Quarry 500kV Transmission Line
Scope: 68.3 miles of 500kV
Location: Palm Beach, Broward, and Miami-Dade Counties, FL
Client: NextEra Energy Resources
Irby Construction was awarded the Corbett – Sugar – Quarry 500kV Transmission Line Project on January 16th and immediately started work.
The project runs 69 miles from the Corbett and Sugar substations in Palm Beach County down to the Quarry substation in Miami-Dade County. It is a 500kV, single circuit, triple bundled line carrying 1272 ACSR/AW, (one) .472” OPGW, and (one) 7#8 AW OHGW.
The full scope of work also includes surveying, clearing the right-of-way, building access roads and structure pads, installing drilled pier foundations and anchor piles, and setting steel H-Frame structures and 3-pole concrete deadends. The majority of this line traverses through the environmentally sensitive Florida Everglades.
Unique to this project will be the construction of 15 miles through canal waterways utilizing barges, concrete pump lines, and amphibious equipment. This project will serve as a critical tie between two 500kV substations to increase reliability on the Florida Power & Light grid. Construction began on January 22, 2018 and is scheduled to complete in May of 2019.
Start Date: January 2018
Completion Date: In progress
