We pride ourselves on delivering the highest quality service, by bringing all 3 phases of electrical contracting together: Safety, Service and Productivity.

Three Phase Line Construction, Inc. (3Phase) located in Farmington, New Hampshire has been serving the electric utility industry since 1996. Our highly skilled professionals, extensive fleet equipment, and an unprecedented work ethic represent best in class.

3Phase Line’s expertise lies in substations and switchyards, transmission services, distribution and telecommunications, and are all constructed while maintaining the strictest environmental and safety compliances. The company was created by partners who each worked 20+ years as linemen crisscrossing the country working on a full array of energy projects. They built the company’s culture on a foundation of keeping the workers safe, well equipped, and fully supported. That culture remains with 3Phase to this day and permeates every division, project, and crew of the company.

In 2007, 3Phase was acquired by MasTec, a publicly owned, multi-national infrastructure construction company. The change in ownership allowed 3Phase to keep its existing culture while adding an unequaled financial base and senior management support to broaden and improve our operations.

After 16 years of operations, 3Phase has a corporate resume showing successful completion of projects in all areas of distribution, substation, transmission, and communication work. We pride ourselves on delivering the highest quality service by bringing all “3Phases” of electrical contracting together: Safety, Service and Productivity. We have a proven track record of completing projects on time or ahead of schedule and within budget, while delivering the highest level of customer satisfaction.

3Phase is a member of the OSHA Electrical Transmission & Distribution Safety Partnership and National Electrical Contractors Association (NECA).

3Phase is a signatory International Brotherhood of Electrical Workers (IBEW) contractor with a federally recognized Lineman Apprenticeship program.
