Loy Clark Pipeline Co., founded by Mr. Loy S. Clark, was the first pipeline construction company in Oregon. Loy Clark brought the first natural gas lines into Portland, Oregon, beginning in 1957. Over the next several decades, Loy Clark diversified its services. Our list expanded by adding electrical/communication infrastructure, directional drilling, asphalt paving, saw cutting and vacuum excavation. We were one of the first companies to begin using horizontal directional drills, it is now the primary method to install conduits and pipe for electrical, communication and natural gas industries.
