Blue Lake Expansion Project Wraps Up, Produces Hydropower Stakeholders and Valued Subcontractors: • The City and Borough of Sitka • McMillen LLC • Gilbert, Gilkes & Gordon, Ltd. • Blue Lake Tunnelers (Redpath/Frontier Kemper JV) • NAES Power Contractors • ASRC McGraw Constructors • STG Inc. • Southeast Earthmovers

Water flows from the Blue Lake Powerhouse tailrace (inset) after the turbines are powered on for the first time following a successful 63-day generation outage during which we completed the tie-in to a new intake. n a blue-sky day in mid-November, Blue Lake reached a new depth, nearly spilling over the Blue Lake Dam’s new spillway more than a year Oearlier than project designers anticipated. That same day, a new 15.9 MW powerhouse 2 miles downstream from the dam came to life. Constructed to secure energy independence for the small, remote town of Sitka, Alaska, the powerhouse that day was turned over to the City and Borough of Sitka on schedule and within budget. As Barnard’s work on the Blue Lake Expansion Project draws to a close in Southeast Alaska, Sitka’s Electric Department is at the helm of this new three turbine/generator powerhouse, a new 1.7 MW Fish Valve unit turbine/generator, a refurbished water treatment plant and the 18,000-lb. gate that controls a new intake from the rapidly rising . Completion of the project represents the culmination of many years of planning, fund-raising and permitting and two years of construction to complete the powerhouse, new intake and gatehouse, and to raise the existing 145-foot-tall concrete arch dam by 83 feet to its geotechnical maximum height. The success of this challenging, multi-faceted project is directly attributable to the hard work and expertise of all stakeholders and subcontractors, to whom we owe many thanks.

NYCDEP Celebrates Successful Dam Project notables

On Dec. 1, Barnard hosted a press conference at our Bozeman, Montana, home office during which Gov. Steve Bullock promoted the Gordon Butte Pumped Storage Hydro Project. Project owner GB Energy Park, LLC is currently pursuing FERC licensing. Barnard is slated to construct this 400 MW project on private land in rural Montana. A group of officials, work crews and the press gathers to celebrate completion of the concrete and civil portion Barnard’s of the Gilboa Dam Reconstruction Project, an event hosted by the City Department of Environmental Eisenhower Protection in the spillway channel of the dam. Johnson Memorial Tunnel Fixed Fire ore than Halloween was celebrated on Oct. 31 in Central New York. The New York Suppression System City Department of Environmental Protection (DEP) erected tents in the spillway and (FFSS) Project Team set up a podium below the impressive 120-foot high, 2024 LF dam face to champion achieved its first two M milestones for the the early, on budget completion of a complex project necessary to protect downstream Colorado Department communities as well as a valuable water source for the City of New York. Gilboa Dam holds of Transportation back Schoharie Reservoir, the northernmost reservoir in the NYC water system. The dam with the issuance required reconstruction of the spillway control section to address existing deterioration, improve of NTP 1 and LNTP 2. These Notices to hydraulic flow, and enhance structural stability. The reconstruction involved phased water Proceed included diversion management, selective demolition, buttressing of the spillway with new stair-stepped six successful test mass concrete, and reconstruction of the spillway channel and plunge pool underdrains and burns applying the slabs. The project also included modifying and strengthening the east, west and north spillway team’s FFSS design criteria. Design for training walls, strengthening the upstream embankment using stone fill placed from barges, and this $20 million tunnel installing extensive dam safety instrumentation systems. Our JV Team and the design provided adaptation project by Gannet Fleming/Hazen and Sawyer, PC, JV were put to the test during construction when nears completion. Construction is slated the site was hit by two major hurricanes, Irene (2011) and Sandy (2012). Despite experiencing to begin in early 2015. a 500-year flood with Irene, the project remained on schedule with great effort. Barnard constructed the project in a joint venture with D.A. Collins Construction Company, Inc.

Barren Ridge Transmission Project Launched With the much-anticipated issuance of Notice to Proceed in mid-October, Barnard’s Barren Ridge Renewable Transmission Project Team snapped into action on this 61-mile Engineer-Procure-Construct (EPC) 230kV transmission line project for the Los Angeles Department of Water and Power. While several Barnard Team members mobilized to develop the design with our partner Black & Veatch, others traveled to Shanghai, China, and Monterrey, Mexico, to ensure that cable and tower fabrication and testing are progressing according to the 18-month project’s aggressive schedule. Construction is anticipated to begin in Spring 2015. 2 Barnard inside Barnard Barnard Work with TVA Expands across Seven Dams Barnard’s role in structural modifications work for the Tennessee Valley Authority has expanded over the last several months to include work on seven dams within the TVA system. After wrapping up anchor installation work on Cherokee and Douglas dams in November, our crews have moved into fabricating and installing replacement bulkheads, constructing new concrete floodwalls, building a weighted berm and collection system for relief wells, as well as additional work focused on installing anchors in dams constructed over the last 60 years. Nicholson Construction Co. remains our anchor subcontractor,
