Quality, reliable construction is what you’ve come to expect from Great Southwestern Construction on any transmission project.

We have completed over 100 transmission projects ranging from 69kV through 500kV, and more than 1,000 miles of optical ground wire (OPGW).

While maintaining good relationships with landowners and respecting and addressing environmental concerns on right-of-ways, we have completed projects in some of the most challenging of conditions. From farmland to mountains, in solid rock or crossing bays, on flat sandy soil or on steep rocky inclines, using helicopters or barges, we get the job done.

We have experience with structures from 60’ wood poles (including phase raising) up to 280' steel structures. We construct steel lattice towers and tubular steel poles using both direct embedment and steel reinforced concrete caissons in a wide variety of soil conditions.

We team with some of the best engineering firms in the country to ensure the client is getting the highest quality projects performed by a confident design/build partnership.

Our Procurement Department has a broad understanding of how to order, package and expedite every facet of transmission line material and assembly units. We have been solicited on numerous occasions to assist utilities in how to optimize their procurement processes.

We have assisted in transmission storm restoration for numerous clients across the southern states including: Entergy, South Mississippi Electric, Oklahoma Gas & Electric and Florida Power & Light to name a few.
