“Our partnership with Advantage Engineers has proven to be a wise choice," said Trevor Knoebel.

Advantage Engineers has provided geotechnical and structural engineering, foundation and retaining wall design, and construction oversight services for ‘Impulse,’ a new steel roller coaster for Knoebels Amusement Resort located in Elysburg, Pennsylvania. Advantage Engineers’ work began in June 2014.

“Our partnership with Advantage Engineers has proven to be a wise choice. From our first interactions in planning the design with their team through the oversight and completion of the foundation construction, their level of confidence and expertise has made us feel comfortable with the process,” said Trevor Knoebel, fourth generation member of the Knoebel family and member of the ‘Impulse’ project team. “They were able to answer all of our questions and concerns as we progressed through the project and they stood behind their word and commitment to Knoebels.”

Throughout the multi-phase project, Advantage completed a subsurface field investigation including test borings and a laboratory testing program. Structural engineering included design of the foundation system for the coaster. Construction observation and materials testing services included the documentation of drill depths, casing and reinforcing steel installation, and concrete placement for 159 drilled shafts and 16 combined caisson caps. Additionally, Advantage provided retaining wall design for two walls up to 251 feet in length.

“We’ve completed thousands of projects which included either geotechnical engineering analysis, foundation design or construction oversight services,” said Dave Buckwalter, Senior Project Manager with Advantage Engineers. “With this project, we have combined all three services for the ‘single largest project in Knoebels Amusement Resort history’ and to be a part of that is a big deal.”

The ‘Impulse’ roller coaster, scheduled to open spring 2015, will be the resort's first looping steel roller coaster since 2005. The ride includes 2,000 feet of track and a vertical rise and drop of 98 feet. The ‘Impulse’ features stadium-style seating and lap bar-only restraints on individual eight-passenger vehicles.
