About the Project

The Mt. Olympus Indoor Water Park expansion was a combined effort between Holtz Builders, Inc., Ramaker & Associates, and Badger Pool adding 22,500 square feet of indoor space in just over 10 months. Medusa’s SlideWheel, America’s first rotating waterslide, stands over 74 feet high and spans nearly 100 feet in width. It entails 443 feet of waterslides wrapped in an intricate tangle of tubes on a horizontal axis that allows the entire ride to rotate continuously 360 degrees as four-person rafts are launched every 30 seconds into the perpetually spinning slidewheel. Riders then propel down a serpentine slide 390 feet into an exit plunge pool. Due to long lead times, materials were ordered from the preliminary plans to meet the hard deadline of Memorial Day, eliciting 79 RFIs and 17 construction bulletins. With more than 44,722 total work hours, delivery coordination, staging plan, and active work on a tight jobsite were essential. Daily huddle meetings established buy-in, encouraged teamwork, maintained safety, and ensured that details of every section were per plan and specifications.
