Site work for a mixed-use development in The Dalles, Oregon. Completed plans call for site work for a water / sewer project.

PN-W9127N25RA0120003 This update adds an additional week to the solicitation. New closing date is 06/20/2025. *This update adds in two videos of the transformers and where the work will be conducted. The U.S. Army Corps of Engineer (USACE) Portland District intends to solicit construction firms who are interested in submitting a competitive firm-fixed-price proposal for this project. This announcement is for the construction/modification/repair of The Dalles T9, T10, and T11 transformers located in Klickitat County, Washington and Wasco County, Oregon. Project Scope: The US Army Corps of Engineers (USACE) Portland District seeks Heavy and Civil Engineering Construction Contractors who can provide construction services for The Dalles Lock and Dam ("the Dalles" and "TDA"). The Dalles T9, T10, and T11 transformers are identical 230,000/132,790-13200 Volt, 233,000 kVA class Forced Oil and Forced Air (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. Acquisition Strategy: Proposals will be evaluated utilizing the Best Value Tradeoff source selection method. Nonpriced factors are equal in importance. This acquisition will result in a single fixed-price contract. Magnitude of Construction: The estimated cost of the project is between $3,000,000 and $5,000,000. Set Asides and Codes: This acquisition will be 100% Total Small Business Set-Aside. The North American Industrial Classification Code (NAICS) for this acquisition is NAICS: 238210 - Electrical Contractors and Other Wiring Installation. The PSC Code is Z2MD - Repair or Alteration of EPG Facilities - Hydro. The small business size standard is $19 million. System for Award Management (SAM): Offerors must register in the SAM at https://www.sam.gov prior to submission of bids and prior to receiving an award. Point of Contact: The USACE-NWP Contracting Office will be the sole point of contact for this action. E-mail responses to the Primary Point of Contact, Joseph Jarvis at joseph.b.jarvis@usace.army.mil. E-mail is the preferred method for receiving responses to this notice. THE GOVERNMENT RESERVES THE RIGHT TO CANCEL THIS SOLICITATION EITHER BEFORE OR AFTER THE CLOSING DATE. NO REIMBURSEMENT WILL BE MADE FOR ANY COSTS ASSOCIATED WITH PROVIDING INFORMATION IN RESPONSE TO THIS PRESOLICITATION NOTICE OR ANY FOLLOW-UP INFORMATION REQUEST. *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document. n general, the Government is expecting the following overall work concept for a single transformer with the same action performed on all three transformers: Repeat steps for T9 and T11 except for step 4: there may not be any failed sections. 1. Perform electrical pretesting of as-found condition and remove two oil samples for analysis by two independent laboratories. USACE will make available any reports, photos, and test data and allow inspection. The Dalles Project will manage lock out / tag out responsibilities. 2. Drain the approx. 14,600 gal. transformer oil into clean, dry baker tanks provided by Contractor including all secondary containment and spill prevention measures. The oil is chased by dry air meeting ASTM D 3283 dew point requirements and the tank positively always pressurized there is no active work ongoing. Transformer T10 has 3,142 gallons already removed and stored onsite in a dirty oil storage tank that will not be reused. Transformer T9 and T11 indicate a normal oil level. 3. The neutral may be repaired with the in the manner most feasible to achieve a long-term repair solution. The Contractor can decide which will provide the best solution based on their equipment, personnel, and experience. The Government prefers minimal handling and disassembly but recognizes the challenges of internal transformer repair work involving cutting and re-brazing or crimping internal connections. 3a.
