Inside the new SkyWest Maintenance Hangar Facility.

Commonwealth Electric Company of the Midwest’s (CECM) team in Tucson, Arizona, is working on completing a $3.75 million electrical contract with Big-D Construction Southwest for SkyWest Airlines. The new SkyWest Maintenance Hangar Facility, located on Tucson International Airport property, consists of a 32,700-square-foot office and parts area, a 30,000-square-foot shop area, and a 100,000-square-foot hangar area.

The airport taxiway, with new airport lighting, feeds into a large apron area with 40-foot LED pole lights to house large airplanes. The hangar itself, which reaches 70 feet above the floor, has three large sliding bay doors that can fully open to house and service up to six large aircraft. The office and parts area serves both SkyWest office personnel and parts supplies. The new shop area is equipped with various machines, equipment, and power receptacles, including many overhead power cord drops, to support interior repairs, parts painting, and other functions.

The project is powered by a 3,000-amp, 480-volt Service Entrance Section (SES), which includes a distribution switchboard, panelboards, and step-down transformers throughout the building. It also features several emergency inverters, an Uninterruptible Power Supply (UPS), a natural gas generator, cable trays, and special systems rough-ins. The structured cabling system for the entire facility was a separate contract with the owner and was managed by Project Manager Freddy Carlisle and Foreman Rudy Martinez, along with their low-voltage crew. The building also contains a complete fire alarm system, a hangar infrared (IR) detection system, and a Distributed Antenna System (DAS) to meet building code coverages.

We would like to recognize and express our appreciation to General Foreman Mat Merriman, Foreman Collin Deputy, and a dedicated field crew of 28 electricians at peak size. This hardworking team has been putting in 58 hours per week since the end of October, overcoming steel building and other delays, to complete the project on schedule with a March 2025 completion date.
