Grand Falls Casino

A Vegas-inspired casino, superior shopping, a luxurious hotel, top-notch entertainment, a relaxing spa, first-class dining, and a world-class golf course perfectly describe Grand Falls Casino & Golf Resort. A destination like no other in the Tri-State region, every aspect of the resort is designed for one very special purpose — your total enjoyment. The resort is loaded with exciting gaming, culinary delights, luxurious hotel rooms, top-notch live entertainment, a relaxing spa and one-of-a-kind shopping.

The facility has 900 slot machines, 24 table games, 8 poker tables, a 100-room hotel, indoor/outdoor swimming pools, a buffet line, fine dining, a café/deli, a show lounge, a 1200-seat event center, a full service spa, gift shops, boutiques, a wellness center, and coming in 2013—an 18-hole golf course designed by golf course architect, Rees Jones.

Our Sioux Falls team (formerly American Technical Services) provided geotechnical and construction materials testing on this $120 million new casino.


Project Details:

The casino portion of the project is a steel frame with steel stud backup system on cast-in-place foundation walls. A portion of the casino has a walkout lower level which houses the computer/electrical systems for the casino mechanical/electrical rooms and also the housekeeping facilities for the hotel. There are two elevator shafts connecting the casino to the hotel. These shafts rise 60’ out of the ground and had to be built free-standing to allow for the wood frame hotel to be tied in. The three-story, 100-room hotel (with six fireplace suites) is a wood-framed structure with a walkout terrace level housing the spa areas and future golf clubhouse. The terrace level walks out to the outdoor pool and plaza which will overlook the future golf course. The indoor pool has a hot tub that swims through to the outdoor hot tub. There are also free-standing colored rockface water pump and fire hydrant buildings.

Due to soft soil conditions on a portion of the site, a surcharge was placed and monitored to determine settlement.  The northern portion of the site had slightly better soils and was placed on an engineered fill system so that construction could begin on schedule while the surcharge was in place.
