Gencorelli Engineering effectively designed a helical pile foundation and connections for zoo’s Amazon, Jaguar and Primate exhibit nettings. The helical pile foundation solution was essential for keeping the guy wires tensioned and secure into ground. The project used complicated angles and batters to ensure an inline tension load with a strong connection. A key feature of the project was the 18’ King Mast which was in a central area that held 8 guy wires for netting. The King Mast was located where visitors walked so keeping the helical pile tension guy wires to high loads with minimum piles was essential. The great success of this project lead the Houston Zoo to apply the same approach.
