Matrix NAC: supporting critical infrastructure through union labor since 1986

The direct hire union division of Matrix Service Company, Matrix NAC has provided procurement, construction, maintenance and repair services to the energy and industrial markets across North America since 1986. Our unparalleled commitment to safety, quality and client success has made us an employer and provider of choice throughout the years, as well as earned us industry recognition year after year.

Parent company Matrix Service Company began its union operations through Matrix NAC in 1986, but Matrix NAC increased its experience and capabilities exponentially through its acquired businesses which include S.M. Electric and Kvaerner North American Construction. This proud legacy extends as far back as 1946. Today, Matrix NAC enjoys a long-standing reputation for excellence across a host of services including large capital construction, oil and gas storage, power generation, power delivery, integrated iron and steel and refinery and petrochemical work.

We maintain strong relations with national labor groups with active participation in the National Maintenance Agreement Policy Committee and other labor management committees and associations, both on local and national levels. These crucial relationships support North America's craftspeople and ensures that we effectively staff projects with the most qualified craftsmen on the continent.

Community Involvement

We go above and beyond corporate responsibility to make sure we touch lives, affect the community and help those in need. From supporting the United Way to local food drives and holiday gift collections, Matrix employees are passionate about giving back and supporting our communities.
