Three Rivers Casino

This 100,000 square-foot casino for the Confederated Tribes of Coos, Lower Umpqua & Siuslaw Indians, located in the picturesque coastal sand dunes in Florence, Oregon, replaced a tent structure, quadrupled the gaming floor plan, and provided state-of-the-art recreation and amenities.

At the recommendation of JE Dunn Construction Company, Stearns was awarded the project to assist the Engineer-of-Record and design and construction teams by managing all aspects of the structural steel process, from providing detailing services and drawings for fabrication and construction, to procuring all structural steel materials and administering an aggressive steel construction schedule. One of the unique challenges of the project was the use of heavy equipment to erect the structural steel on a field of fine blown sand. Stearns devised a series of portable stabilizing mats made from heavy, recycled conveyer belts on which forklifts, cranes, and man-lifts traveled to avoid immobilization. This creative solution allowed Stearns’ construction team to assemble the structural steel frame in only 6 weeks.

Butch Fiedler, Project Manager, JE Dunn Construction Company stated: “R.F. Stearns did an exceptional job under very tight time constraints on the Three Rivers Casino project. Their team was always available to step in and lend a helping hand no matter what the predicament may have been. I really enjoyed working with Stearns.”

Another significant aspect of the project is the wood-clad porte cochere at the casino entrance. It was designed with apex moment frame beam roofs at each end and an awning-style canopy between them that followed 45 degree splay walls. The porte cochere required close coordination of miscellaneous custom plates for attaching wooden faux beams to the main steel structure, creating the illusion of hips and valleys within the wooden roof. In the special events area, two 90-foot trusses made from tube and wide flange were shipped in halves to facilitate logistics and spliced together at installation. In the gaming area, long steel joists were field spliced to create huge open spaces.

The entire construction team worked in close collaboration to successfully complete the steel-framed casino structure on time and within budget.
