Port St. Joe to Callaway
230kV Rebuild

Type: Transmission
Scope: 34 miles of 230kV
Location: Port St. Joe, FL
Client: Duke Energy

Hurricane Michael made landfall on October 10th, 2018 near Mexico Beach, Florida. Duke Energy’s 230kV 34-mile PX line from Port St. Joe to Callaway was damaged beyond repair. On November 15th, Irby was awarded the job from Duke with three months to remove and rebuild the line. Our preconstruction meeting was held in Wildwood, FL, on November 19th and work officially began on December 3rd.

Rufus Killen led field operations over seven subcontractors: Aldridge Electric, A&J Steel, HeliService Powerline Solutions and FireHawk Helicopters, ROW Masters, Probst Electric, and Thomasson Company. Gerald and Tammy Westmoreland ran all office operations while still handling their other Irby job assignments. Working six days a week, 12 hours per day, we were able to beat the scheduled completion time with no injuries and no environmental incidents. At the busiest time of the project, we had 220 crew members consisting of wire/tower removal crews, four drilling crews, multiple framing/setting crews spread over four yards, three helicopters (one BlackHawk and 2-MD500s), wire crews, one eagle’s nest, two boats, and well over 10,000 mats. With all the devastation, logistics and housing was an issue, many crew members driving over an hour and a half each way to the line.

We are proud of a few milestones- Day 39: 328 holes drilled and bases set; Day 43: all pole tops framed and set; Day 64: grounds removed and line turned over to Duke. Probst Electric averaged pulling and clipping a mile of wire a day with the help of two helicopters.

AEP Oklahoma

Type: Substation
Scope: 
Rebuild entire 22 breaker 138kV Substation Yard
Location: Oolagah, Oklahoma
Client: AEP Oklahoma

Irby Construction was awarded this project in October of 2017. The project consists of complete demolition of a 22-circuit breaker ring buss and construction of a new 22 breaker ring buss in sections. This project is unique in the way that it is being constructed. This project involved installing two new 138kV bays on the outside of the existing station and transferring lines to the new bays. Once the lines were transferred demolition on the existing substation work could commence. Irby is building and demoing one entire bay at a time due to extreme outage constraints. This project takes immense coordination with AEP and everyone onsite. Irby has been through 19 outage plans to accommodate the construction on this project. This station is key infrastructure for AEP. This project provides electricity to the entire Tulsa, Oklahoma area as well as sections of Kansas City.

Irby continues to make the outages as requested by AEP. Irby has also worked very hard to achieve AEP’s & Irby’s goal of Zero Harm on this project and will continue to do so.

Start Date: November 2017
Completion Date: November 2019

Type: Substation
Scope: Replacement of six 138kV breakers
Location: Fredericksburg, TX
Client: Lower Colorado River Authority

Irby Construction was awarded the Gillespie Substation project in February of 2018. The scope included the replacement of six 138kV oil-filled circuit breakers with six new 145kV 3000A 40kAIC circuit breakers. This project also included replacing all the busswork and jumpers on the high side as well as installing new control cable, and junction boxes at each breaker stand. From there we were to wire the existing cable in the new junction box to the new breakers.

This project also consisted of testing 108 CT’s on all the new breakers and providing test reports to LCRA. Irby contracted out to Electrical Reliability Services, Inc., to perform testing and commissioning services. 

Throughout this project, Irby was able to display its craftsmanship specifically pertaining to aluminum busswork, bending and termination, as well as control cable installation and termination. 

Start Date: March 2018

Lonestar Transmission Substation  

Type: Substation
Scope: 345kV Motor Operator Installation Project 
Location: Sweetwater, Albany, Hillsboro, & Corsicana, TX
Client: NextEra Lonestar Transmission

Irby Construction was awarded a series of upgrade projects from NextEra Lonestar Transmission to retrofit 120 MOABs on existing hand-operated 345kV switches. The project consisted of upgrading four major transmission stations with the maximum distance between them being 270 miles apart. The stations are: Novaro Switch Station, Sam Switch Station, West Shackelford Switch Station, and Claytonville Switch Station.

This project took daily, if not hourly, coordination/communication between Lonestar Transmission Construction Representatives and Irby’s onsite foreman to ensure outages were delivered to multiple stations in one day. Irby worked Monday through Saturday, eight hour days to accomplish the replacement and installation of motor operators per the stringent outage schedule. This project had Irby on its toes at all times due to all the transportation between the stations to perform the swap outs during the outages.  

Irby performed the construction to Lonestar’s strict standards of craftsmanship and safety without incident. 

Start Date: July 2018
Completion Date: January 2018
