EDM: The Attractions Architect's Secret Weapon

Since 1975, EDM has been theme park and visitor attractions architects' go-to firm for engineering design. Projects include major ride and coaster foundations, loading stations, theatres, animal life structures, thematic elements, restaurants, kiosks, maintenance facilities, electrical distribution, boiler plants, and shade structures. Locations include key St. Louis attractions such as the Muny, Union Station and Grant's Farm, as well as Hersheypark, Busch Gardens, SeaWorld, Universal Studios, Sesame Place, Silver Dollar City and Six Flags.

The St. Louis Wheel

Union Station | St. Louis, MO

The newest attraction on the St. Louis horizon, this 200-foot high observation wheel has 42 fully-enclosed climate-controlled gondolas that can seat up to six adults.  EDM’s structural design for the Wheel foundation includes 86-foot long reinforced concrete piers drilled to the underlying bedrock formation. EDM also designed the concrete loading platform, and foundations for the electrical control building and the converted shipping containers used for the ticketing office and vendors.

Infinity Falls River Raft Ride

SeaWorld | Orlando, FL

EDM, as a subconsultant to PGAV, provided structural design for the entire run of 1,700 LF of trough, flume and reservoir including foundations for all equipment and 600 LF of elevated walkways. EDM’s structural design considered that, in about 7 seconds, 900,000 gallons of water fill the troughs, and four massive pumps push water into the troughs at a level that would fill a large swimming pool. EDM was also responsible for the foundations of the ride’s inline station with guest loading into boats on a conveyor as well as a covered queue building, entry icon and sign, maintenance building and boat hoists.

Electric Eel Coaster

SeaWorld | San Diego, CA

The Electric Eel is a multi-launch coaster, with several thrusts of accelerations throughout the ride. EDM provided foundation and associated structural engineering services with PGAV as lead designer. The project also included a 450-SF educational exhibit, ride station, maintenance building, locker space and shade structures. To meet seismic and static settlement criteria, EDM’s engineers designed a ground improvement solution that utilized cement deep-soil mixing with more than 200 6-ft-diameter columns down to 40-ft depths to support the 11,000-SF mat foundation slab.
