Electric and Gas Utilities

History:
Merrick has provided professional services to the electric and gas utilities since the company’s inception in 1955. Merrick’s focus in the early years was on surveying and design services for electrical transmission and distribution projects throughout the Rocky Mountain region. Most notably Merrick successfully completed a 150-mile 500Kv line for the U.S. Department of the Interior’s Bureau of Reclamation. The staff grew as the company’s reputation for excellence expanded. Merrick’s professional service capabilities were adapted to meet their customer’s needs for full engineering, procurement, and construction management services.

Today:
Today Merrick offers a full range of professional services for the electric and gas utility industry service areas including generation, substation design, surveying & mapping and high pressure gas design.
