About MK

Morrison Knudsen Corporation began contracting in 1912 when Morris Knudsen allied with Harry Morrison to construct an irrigation canal and a pump station in Idaho. Two years later the Company built the Three Mile Falls Dam in Oregon establishing MK as the premier dam builder in the world. The Company moved onto the Hoover Dam leading a joint venture that built the dam two years ahead of schedule during the Depression.

Since that landmark project the Company has built some of the world’s largest harbors, airports, freeways, rail lines, factories, oil refineries, air bases, naval stations, fuel storage facilities, missile silo’s and systems, radar stations, rocket launching platforms, space control command centers including the Apollo and Space Shuttle launches, military communication systems, developed the largest coal, gold, silver, copper, bauxite and molybdenum, lignite and limestone mines.

We were the lead contractor in the joint venture that constructed the largest naval base in the world at Cam Ranh Bay, Vietnam during the war. Additional war time projects included air bases, hospitals, communication facilities, water supply systems, power stations, barracks, command centers, power transmission lines, highways, bridges and loading facilities. It still stands as the largest construction project ever executed over a five year period, $55 billion in today’s dollars.

The Company has been involved in the construction of seven of the top ten projects in the world determined by the International Right of Way Association. They include the Interstate Highway System, where MK is a top ten contractor in the field; Florida’s Turnpike Suncoast Parkway, the Hoover Dam, the Alaska Pipeline, the Austin Clean Water program, 2nd Tacoma Narrows Bridge, and the City of Phoenix Light Rail. The Hoover Dam was also ranked in the top five construction projects by the American Society of Civil Engineers categorizing it as one of America’s Seven Modern Civil Engineering Wonders.

MK has built the largest aluminum smelter in North America at Kitimat, BC where the Company constructed a dam and all power transmission for the plant. It built the project’s harbor along with all infrastructure at the site including the highway and bridges into the project. Since then the Company’s expertise has constructed similar projects to Alcan throughout the world.
