Duke Construction and Excavation was established in 1995 with family members Jim Dukart (father), Steve Dukart and John Dukart, two of Jim's sons.

Our first equipment purchase was a 1984 Mack dump truck. Steve and John were currently working for an excavation contractor. Steve was a jobsite foreman for six years and John was a truck boss for three years. John resigned and stepped into their own 1984 Mack dump truck and hired out to local excavation contractors. After one year, Steve decided to leave his foreman job and join John as owner/operators for Duke Construction and Excavation.

With the purchase of a 315 cat excavator, we did jobs from new residential site work to cleaning up properties from the big flood of 1996 to putting in new horse arenas. As the year went on and now with two big home builders as customers and doing sixty dig outs a year, we turned to oldest brother Mike Dukart for help. Mike had 6 years of experience in excavation and demolition.

Now with three brothers as partners, any one of us could operate, lay pipe, or drive truck. As the residential construction market declined in the late 1990's we turned to doing commercial site work. With many pieces of equipment, a 10 man crew and Lisa Dukart as office manager, we can handle jobs as small as one thousand dollars to as big as three million dollars.

Duke Construction and Excavation,LLC. specializes in doing jobs that a lot of excavating contractors would pass on because of the difficulty. We specialize in excavating for plumbing contractors where they need a ditch right on grade at a perfect 1 or 2 percent slope so all the plumber has to do is lay the pipe. We also specialize in storm water managment and city of portland nonconforming sanitary sewers.

Duke Construction and Excavation,LLC. takes pride in doing the job right the first time and keeping a clean and safe job site not just for our crew but for all the sub contractors on the job site.
