About this opportunity
The U.S. Army Corps of Engineers (USACE), Portland District, issued this Special Notice to announce an industry day event regarding the repair of transformers 9, 10, and 11 at The Dalles Dam in Oregon. This is informational and for market research purposes only and is not a request for proposal, quotation, or bid. The notice seeks heavy and civil engineering construction contractors capable of servicing the three identical 233,000 kVA transformers manufactured by General Electric in 1972. The primary transformer in question, T10, has been out of service since 2018 due to a failed high-voltage neutral conductor, and similar failures in transformer T8 have provided valuable lessons for the repair approach. The virtual industry day event was scheduled for January 29, 2026, at 0900 hours Pacific Standard Time to provide project updates and gather industry input on construction risks, capabilities, and strategies.
USACE is conducting this market research to evaluate approaches to the transformer repair project and to support solicitation development and commercial item determination. Interested firms were required to submit completed RSVP and survey forms with an original deadline of December 12, 2025, to receive the Microsoft Teams meeting link and participate in the virtual event, with responses to be submitted to joseph.b.jarvis@usace.army.mil. The government provided two industry practice comparison surveys requesting contractors to assess whether specific technical requirements align with, fall below, or exceed standard commercial practices, with responses to inform procurement strategy. The estimated contract magnitude ranges from $5 million to $10 million with a Firm-Fixed Price Construction arrangement and target award in December 2026, following an RFP release in May 2026 and proposal submission in July 2026. All interested contractors, including small businesses, are eligible to participate in the market research process, though contractors must be prepared to meet cybersecurity compliance requirements (DFARS 252.204-7021 and 252.204-7025 for CMMC) and address significant operational constraints such as limited crane access, restricted deck space, and weather-dependent Columbia River conditions.

U.S. Army Corps of Engineers - Announcement from Portland District (NWP)
Repair of transformers 9, 10, and 11 for The Dalles Dam, OR.
This is a SPECIAL NOTICE and is for informational/market research purposes only. THIS IS NOT A REQUEST FOR PROPOSAL, QUOTATION, OR BID, NOR A SYNOPSIS OF A PROPOSED CONTRACT ACTION UNDER FAR SUBPART 5.2.
Notice Details: The U.S. Army Corps of Engineers (USACE), Portland District is hosting a one-hour virtual industry event at 0900 hours Pacific Standard Time (PST) on 29 January 2026 to provide a project update and to gather industry input as it evaluates project construction risks, industry capabilities, and strategies for the project below:
Firms who respond to this announcement with completed RSVP form and Survey form will be provided further details and a link to the virtual meeting. The Government will provide the presentation slides following the event. It is also requested each firm provide responses to a questionnaire to be launched at the conclusion of the event. Responses will be considered for use in the solicitation development.
Project Site Backgrounds/Scopes: The US Army Corps of Engineers (USACE) Portland District is searching for Heavy and Civil Engineering Construction Contractors who can provide construction services for The Dalles Dam. The Dalles T9, T10, and T11 transformers are identical 230,000/132,790-13200 Volt, 233,000 kVA class FOA three-phase transformers manufactured by General Electric’s Pittsfield, Massachusetts facility in 1972. The T10 transformer was forced out of service in 2018 due to a failed high-voltage neutral conductor internal to the tank between the H1 and H2 windings. All three transformers are located outside on the powerplant intake deck on the Columbia River.
A previous identical transformer, T8, also failed in the same manner in 2016 and was dissected during a forensic teardown for root-cause of failure. The neutral conductor is housed in a support tube which reduces oil flow and leads to an eventual complete blockage as the neutral lead thermally upgraded Kraft insulating paper overheats and degrades. Loss of cooling oil further increases conductor temperature leading to an eventual mechanical failure during switching events. The proposed procurement will perform a repair of the failed T10 transformer and improve the neutral conductor support to improve cooling. Via the same action, perform the same improvements of the T9 and T11 transformers to prevent the in-service failure due to the neutral conductor design issue. If there is physical evidence of overheating, replace the neutral conductor.
