Libby Dam Emergency Lighting

The Libby Powerhouse Emergency Lighting project illustrates Green Water’s ability to conduct electrical upgrade tasks, install fire protection mechanisms, and fabricate metal works needed at a USACE dam installation in extreme northwestern Montana.

This is a USACE, Seattle District, managed site at Libby Dam, Libby Montana. The dam, built in the 1970’s, was not constructed with fire partitions, a fire alarm system or other now common life safety features. Green Water is designing and installing a new fire alarm system for the entire powerhouse that includes a heat detection system; custom fabricated lighted directional signs, beam smoke detectors and more.

Wire pulling for new fire protection system inside Libby Dam.

Additionally, we are fabricating and installing new metal stairways and providing complex two-hour fire enclosures around existing stairways and landings, and are installing new elevator car doors (selected to match existing elevator doors that are on the historic preservation register). Green Water is performing all line voltage electrical, installation of fire doors and door hardware, demolition of existing Concrete Masonry Unit (CMU) walls and new concrete walls.

Other work includes design build Direct Digital Controls (DDC), HVAC commissioning, HVAC distribution systems including exhaust and ventilation; testing, adjusting and balancing (TAB); fire extinguisher installation, painting, framing, structural steel fabrication and installation, and more.

Green Water also provided design, engineering and drafting for a structural steel platform installed inside the existing elevator shaft.

Customer Relationships

Green Water has worked closely with USACE to identify potential unforeseen conditions and minimize the cost impact of those unforeseen conditions by presenting sketches, drawings or other information as appropriate.

Benefit to Seattle District, USACE
