Toth & Associates Restores Power to 1,500 People 18 Days ahead of Schedule
Restoring a 60-year-old transmission system in just 30 days with PLS-CADD
About our customer
Toth and Associates, Inc.
Rebuilding a storm-damaged transmission line faster
Established in 2003 and headquartered in Springfield, MO, Toth and Associates, Inc. is a full-service consulting engineering firm serving clients across the United States. After a major storm with winds exceeding 100 miles per hour destroyed 120 transmission poles, Toth was engaged by Prairie Power Incorporated to accelerate transmission line design and rebuild a 60-year-old system across a 6.5-mile corridor in Illinois. Using PLS-CADD and updated field reports, the team streamlined design revisions to support faster, safer power restoration.
Key Takeaways
24-hour turnaround for initial transmission line design
30-day rebuild of 6.5-mile transmission area
18 days saved on the transmission rebuild schedule
1,500 people with power restored
Flexible digital design
Toth and their utility partners worked under an aggressive timeline to rapidly develop plans for a safe and efficient electrical line rebuild. Emerging supply and delivery constraints forced the design team to repeatedly respot, respan, and realign the design based on material availability. Using Bentley’s PLS-CADD, the team created, tested, and refined the design to guide construction, allowing teams to complete reconstruction and restore power to 1,500 homes 30 days after the storm.
Solutions
Real-time coordination across project teams
Engineers, field workers, construction teams, and regulators worked together in real-time to redesign the storm-damaged transmission line while maintaining safety and reliability requirements.
Faster transmission design decisions
PLS-CADD’s automated design functions sped up optimization, bidding, material sourcing, and construction phases—with a project completion 30 days after the storm and 18 days ahead of schedule.
Rapid Response
Using PLS-CADD, Toth and their colleagues quickly developed a digital model for the safe and efficient replacement of the electrical line, with initial design completed a day after the storm.
This restoration project demonstrates what can be accomplished when expertise, innovation, determination, and the right tools come together to serve a community in need.
