EEC - Engineers architects surveyors builders

Experience, Efficiency, Commitment

Experience the Design/Build advantage with Eggart Engineering and Construction. Founded in 1998, EEC has a staff of over 40 professionals ranging from structural and civil engineers, architects, and surveyors, to CAAD craftsmen, construction administration personnel, tradesmen and laborers.

Most Importantly, We build what we design. Our vast spectrum of clients and customers enjoy single source accountability. EEC is the one company there from the beginning stages of conception and design, to the final walkthrough and punch list of a new facility. We provide high quality workmanship, exceptional communication, unmatched customer service, and efficiency gained only through our years of experience.

In 2012 Eggart Engineering and construction was ranked as the 16th largest commercial contractor in the state of Montana, based solely on the value of permits pulled. Quentin Eggart, founder and President, credits this success to the combined experience and creativity of the team he has built over the past decade.

"Everyone is under one roof, and everyone works together. There is a level of accountability there that can’t be created when working with someone across state lines or even across town. Architecture, Engineering, Surveying, and finally construction services melding together efficiently will yield a superior product in a more timely manner. At the end of the day it’s about the client. Essentially our team is able to provide value engineering and timelines that our competition cannot, and that’s been a big part of our growth."
