Corbett-Sugar-Quarry 500kV Transmission Line

Type: Transmission
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

Hurricane Irma

Hurricane Irma

Hurricane Irma

Type: Emergency Restoration
Scope: Over 300 Linemen 
Location: Various parts of Florida

As Irby Crews were wrapping up work in Texas following Hurricane Harvey, Hurricane Irma made landfall as the first Category 5 hurricane of the 2017 Atlantic hurricane season. On September 10 Irma’s winds reached 185 mph in Cuba. It was the most intense Atlantic hurricane to strike the United States since Katrina in 2005.

Less than one month after Harvey, but after that same amount of time on the job restoring power, Irby crews packed their bags and headed for Florida rather than going home.

“We had several crews working on a lot of different types of jobs before Hurricane Irma hit, but once we knew that she would hit Florida, they all sprang into action,” Brent Croft, General Superintendent said. “We had crews down in Southern Florida before the hurricane even made landfall so that they could be ready to work immediately after it passed over them.”

More than 300 Irby men performed work during the 2017 hurricane season. Many of those men worked both Hurricane Harvey and Hurricane Irma back to back. In total, Irby teams logged 114,000 restoration man-hours this hurricane season alongside many fellow Quanta companies.

Hurricane Harvey and Irma caused mass destruction to numerous regions in and surrounding the U.S. According to estimates from Moody’s Analytics, damage and lost productivity cost as much as $200 billion.

Hurricane Harvey

Type: Emergency Restoration
Scope: 114,000 restoration hours
Location: Various parts of Texas and Louisiana

On August 25, 2017, Hurricane Harvey made landfall near Rockport, Texas as a Category 4 hurricane. Harvey was the first major hurricane of the 2017 Atlantic hurricane season. It was devastating. Winds as strong as 130 mph left extensive damage to power infrastructure in their wake along the Gulf Coast from Rockport to Southeast Texas and into Louisiana.

Irby Construction crews were prepared before the storm hit. As Harvey made landfall, caravans of bucket trucks drove toward Texas, so the power restoration process could begin as soon as rain and winds subsided.

“Emergency restoration is both the most grueling and the most gratifying work Irby linemen address,” said Chris Swindoll, Superintendent. “Restoring power is often restoring some sense of normalcy for communities hit by these storms. It’s a process we’re proud to be a part of.”

More than 300 Irby men performed work during the 2017 hurricane season. Many of those men worked both Hurricane Harvey and Hurricane Irma, a storm that followed just days later, back to back. In total, Irby teams logged 114,000 restoration man-hours alongside many fellow Quanta companies.

Hurricane Harvey and Irma caused mass destruction to numerous regions in and surrounding the U.S. According to estimates from Moody’s Analytics, damage and lost productivity cost as much as $200 billion.

Comanche Solar Project 34.5/230kV Substation and Interconnection

Comanche Solar Project 34.5/230kV Substation and Interconnection

Comanche Solar Project 34.5/230kV Substation and Interconnection

Type: Substation
Scope: Construction of 34.5/230kV substation, 2.5 miles of 34.5kV interconnection, and an underground 230kV transmission line
Location: Pueblo, CO

Client: CG Power Solutions USA

Irby Construction was contracted by CG Power Solutions USA under an EPC agreement to build the Comanche Solar Project substation and a 2.5 mile 34.5kV interconnection between the east and west solar panel fields of the 120MW generating facility. The scope also incorporated the installation of a 230kV underground transmission line from the substation to Xcel Energy’s generation plant, Comanche Generation Station.

Irby crews mobilized for construction of the greenfield substation in December of 2015, completing the project just six months later. Irby captured construction of the substation via a live stream camera mounted on our construction trailer. CG Power project management teams had 24-hour access to the site and was able to monitor progress from remote locations.

As one of the largest solar farms in the nation, the Comanche Solar farm generates enough power to energize over 31,000 homes east of the Rocky Mountains. Within its 25 year life, Comanche Solar is estimated to produce more than 6 billion kilowatt hours of clean solar energy and is expected to reduce CO2 emissions by approximately 3.5 million tons. This is the equivalent of taking more than 54,000 passenger vehicles off the road. Irby is proud to be a part of this project.

Start Date: December 2015
Completion Date: May 2016

Marshall Ford to Lago Vista 138kV Transmission Line

Marshall Ford to Lago Vista 138kV Transmission Line

Marshall Ford to Lago Vista 138kV Transmission Line

Type: Transmission
Scope: 1.3 miles of 138kV
Location: Austin, TX

Client: Lower Colorado River Authority

Irby Construction was contracted by the Lower Colorado River Authority (LCRA) to replace a 1.3 mile segment of line over the waters of Lake Travis outside of Austin, TX. In March of 2016, Irby began construction on the Marshall Ford to Lago Vista project. The scope included replacing the existing 1233 kcmil ‘Yukon’ ACSS with single 3M Hudson ACCR 1158 conductor.

The entire project included the rebuild and upgrade of the existing 14.5 miles Marshall Ford to McNeil 69kV electric transmission line to a 138kV electric transmission line in its existing 100 ft wide right of way in northwestern Travis County, TX. The two existing lattice towers on either side of the lake remained in place, without required modifications. Due to significant population growth in northwest Austin, in both Travis and Williamson Counties, this project was a necessity to ensure reliability. Irby Construction successfully completed this project in April of 2016.
