In June 2024, Irby Construction broke ground on the Destin Resiliency and Rebuild Projects, an initiative designed to enhance the system’s reliability and capacity for Florida Power & Light (FPL). The job involved rerouting and upgrading Destin’s primary transmission line to increase ampacity and reinforce the grid in one of the Gulf region’s most critical corridors.

The scope included installing new large concrete poles and realigning the transmission path through a densely developed, high-traffic area. Given the job’s visibility and location, Irby implemented strategic night shifts and coordinated closely with local stakeholders, including business owners, to minimize disruptions. 

To avoid costly substation shutdowns, Irby partnered with MG Dyess, a Quanta Services sister company, to perform energized work. This approach eliminated the need for outages and ensured continuous power delivery throughout the construction period.

Extensive pre-construction planning with FPL and early outreach to the local community helped streamline execution. Night construction allowed the crews to stay on schedule without impacting daytime traffic.

Completed on time and under budget, with zero safety incidents, this job delivered significant system upgrades and addressed a long-standing infrastructure need, improving overall grid resiliency for FPL customers.

This project included construction of 8.3 miles of 115kV/69kV line on the Mosaic Mine property in order to reroute an existing line around a future mine site.

The scope of work included setting 67 concrete poles and pulling 6.4 miles of 230kV, with 1.9 miles of 69kV underbuild. Irby also removed 33 structures and 4.5 miles of wire as part of the re-route.

We partnered with fellow Quanta sister company MG Dyess to build a permanent road throughout the right of way and to mat wetlands.

Because road construction was underway at the same time as the T-line work, coordination between the two companies on site was essential to its success. In addition to weekly calls with MG Dyess, the ability to complete the project efficiently required communication and coordination at the field level. Irby and MG Dyess superintendents were key players in the project’s ultimate success.

Thanks to this highly effective collaborative relationship, the work was completed on time and on budget.

Start Date: October 2023
Completion Date: April 2024
