Tacoma Power replaced the towers and power lines that cross Henderson Bay and Burley Lagoon near Purdy, WA. The four lattice towers in the water were replaced with one steel pole, and the four lattice towers on land were replaced with four poles. 

AAC performed marine support to the Prime Contractor, Magnum Power.  AAC's work included pile driving of temporary power poles, pile driving of the new 66" pole base, erection of the new pole, removal of the existing towers and their marine foundations.  AAC will also provided general marine support for Magnum Power during the project.

This project has the following unique characteristics:

• All work is performed within a tidal zone that almost completely dries out
• Crane work is regularly performed inside of and within two 115 KVA transmission lines.
• Worksite lies in a very sensitive environmental area
• The work requires extensive planning and onsite coordination for every movement and activity
