Projects Examples
Hurricane Ike Restoration Work, Texas New Mexico Power
On September 13, 2008 Hurricane Ike hit Galveston Texas as a strong category 2 hurricane with winds of 110 mph. Once a category 4, Ike was recorded as the third costliest U.S. hurricane on record. Hurricane Ike’s unusually large wind shear caused massive power outages throughout Texas and Louisiana. Texas New Mexico Power, a provider of electrical transmission and distribution services to approximately 115,000 customers in the Gulf Coast region completely lost power to this region. TNMP contacted Wilson Construction Company to aid in the hurricane response. Wilson deployed personnel from various states to assist TNMP in their hurricane Ike restoration efforts. Wilson crews were on-site and ready to work Monday, September 15th. Crews and Equipment were brought in from as far as Spokane, WA. Crews worked long hours and through hazardous conditions to get power restored to the region. As with all Wilson projects, “Safety is priority one”, thanks to excellent safety leadership and positive attitudes from crew members, Wilson completed its restoration efforts with 180,000 man hours and no recordable injuries!
Pole Replacement, Bureau of Indian Affairs (BIA)
Wilson Construction crews replaced approximately 340 69kV transmission poles and approximately 520 12.47 kV distribution poles. Aside from three (3) wood service poles, all pole replacements were from wood poles to steel poles. Wilson Crew's performed the majority of work under energized conditions in rough terrain, requiring special desert equipment, during extreme summer heat temperatures. Additional pole replacements were added to the scope of work and at completion Wilson Construction crews had replaced over 948 poles and procured and provided all materials for the project.
Pole Replacement, San Diego Fire Storm, San Diego Gas & Electric
Wilson Construction Crews worked 16-20 hours per day and totaled 17,000 accident free man hours under the extreme fire conditions of the 2007 San Diego fires. Extreme heat from the fires required crews to replace hundreds of transmission and distribution poles; including single poles, H-frames, wood and steel poles, along with risers and URD Primary and Secondary Conductor. Rough terrain and difficult access areas required crews to work off baker boards, hand digs, and helicopters to set poles.
HMC Primary/Secondary Wire Installation, Salt River Project
Wilson Construction crews have pulled over 4.5 million feet of primary and secondary conductor up to 750 MCM CU in residential and commercial developments over that last two years for Salt River Project in Arizona. Crews were also responsible for terminating and energizing conductors and transformers. Wilson Construction crews have been responsible for organizing and inventorying customer provided material allowing for efficient cost savings and a return of surplus material.
Electrical Distribution Upgrade, Phase II, Texas A&M University
This project included the installation of Owner furnished equipment consisting of one 138kV-20 MVA transformer, 12 lineups of 15kV metal-clad switchgear and seven metal-enclosed power factor correction capacitor banks. Additionally, we constructed two 15kV switching station buildings with vaults and over 14,000 feet of 15kV underground duct bank including telecommunications. This project also included furnishing and installing over 150,000 feet of 15kV cable and over 20,000 feet of fiber optic cable. We furnished installed a 138kV substation bay including power circuit breaker and completed other miscellaneous modifications to the distribution system.
Main Electrical Substation Replacement Sacramento Regional Waste Water Treatment Plant
This project included the construction of 4.16kV and 12kV substations, and an underground distribution system, including, installation of foundations and associated steel structures, installation and connection of all major equipment including power transformers and power circuit breakers.
Other key components were the construction of main substation switchgear building, installation of ductbanks and 15kV power cables between 69/12kV power transformers and 15kV switchgear. Installation of all controls systems and underground fiber backbone for local remote operation of all Main Substation equipment, including modifications to appropriate ACCs. Oxygen Plant Substation site preparation includes demolition and replacement of the existing parking area. Additionally, construction of the Oxygen Plant Substation switchgear building and installation of duct banks between 5kV cables from the 12/4.16kV power transformers to the 5kV switchgear.
Design/Build Electrical Upgrade, Kirtland AFB, NM
Wilson's Sacramento office was awarded the 1999 Contractor of the Year Award by the Corps of Engineers, South Pacific Division for outstanding performance on this project.
It was a complex design build project to upgrade and place underground approximately eight miles of the existing electrical distribution system and renovate two substations at Kirtland AFB, New Mexico. Also included was the undergrounding of several miles of communications fiber and copper cable and cable television. As a design build project, close coordination was required and achieved between engineer, contractor and owner.
