Helipad Project

 

The Swan-Tyee transmission line ('STI') was constructed using helicopters as there is no continuous road connection along the remote and rugged terrain of the intertie alignment. Maintenance is conducted using helicopters to access each tower location using temporary log helicopter landing pads built in conjunction with the original intertie construction. These existing log landing pads require replacement with more permanent, safer structures to permit unloading and loading of people and cargo. The project will also include adding helipads to the rest of the SEAPA transmission lines connecting the facilities to the Member Utilities.
