Scope & Requirements

The U.S. Army Corps of Engineers (USACE), Portland District, is conducting market research to identify capable contractors for the inspection, repair, refurbishment, testing, and commissioning of Generator Step-Up (GSU) transformers at The Dalles Dam in The Dalles, Oregon.

The project involves repair of failed Transformer T10 and preventative maintenance and refurbishment activities for Transformer T9, with an optional repair and refurbishment effort for Transformer T11. These transformers are identical 230,000/132,790–13,200 volt, 233,000 kVA, FOA cooled, three phase transformers manufactured in 1972.

Transformer T10 experienced a failure associated with the high-voltage neutral conductor design. A similar failure occurred previously on Transformer T8 in 2016. The Government is seeking qualified firms with demonstrated experience performing inspection, repair, refurbishment, testing, and commissioning of large Class II oil-filled power transformers rated greater than or equal to 230kV and 100 MVA.

The contemplated contract will provide all labor, supervision, materials, equipment, transportation, testing, engineering support, and incidentals necessary to inspect, repair, refurbish, test, and commission GSU transformers T9 and T10, with optional work associated with Transformer T11, at The Dalles Dam.

The contractor may propose either onsite repair activities or transportation of transformers to an offsite repair facility, subject to Government approval.

Internal transformer inspections
Inspection and analysis of transformer winding damage, burns, discoloration, deposits, and conductor failures
Removal and replacement/repair of internal transformer conductors
Removal and installation of high-voltage and low-voltage bushings
Removal and installation of transformer-mounted devices
Replacement of gaskets and seals
Transformer oil draining, containment, temporary storage, disposal, vacuum processing, and hot-oil filling
Transformer electrical testing and oil testing
Sweep Frequency Response Analysis (SFRA)
Winding insulation resistance and power factor testing
Winding resistance testing
Turns ratio testing
Leakage reactance testing
Optional replacement of transformer cooling system isolation valves
Removal and disposal of asbestos-containing materials associated with transformer components.

Anticipated Construction Schedule: USACE Portland District currently anticipates issuance of a solicitation in FY26 with contract awarded in FY27. The estimated period of performance is anticipated to extend through calendar year 2029.

Estimated Construction Cost (ECC): The current estimated construction magnitude is between $1,000,000 and $5,000,000 in accordance with FAR 36.204 and DFARS 236.204.

Number and Type of Contracts: NWP contemplates awarding one (1) Firm-Fixed-Price (FFP) Construction Contract. The acquisition strategy decision has not yet been determined. Maximum small business participation is being sought at both the prime and subcontracting levels.

Anticipated Source Selection Process: The expected method to determine the best value to the government is Best Value Tradeoff.

The current anticipated CLIN structure is as follows:

0001 Mobilization and Demobilization Base
0002 Transformer 10 Repair Base
0003 Transformer 10 Testing and Commissioning Base
0004 Transformer 9 Repair Base
0005 Transformer 9 Testing and Commissioning Base
0006 Concrete Slot Covers Base
0007 Removal and Disposal of Asbestos Containing Materials Base
0008 Transformer 11 Repair Optional
0009 Transformer 11 Testing and Commissioning Optional
0010 Removal and Disposal of Asbestos Containing Materials Optional
0011 Valve Replacement Optional

Optional CLINs are not currently funded and may be exercised by future contract modification.

Interested firms should consider the following anticipated project constraints and challenges:

Restricted access and operational constraints associated with work at an active hydroelectric facility
Coordination with powerhouse operational requirements
Specialized labor and equipment requirements associated with large power transformer refurbishment
Potential long lead times for transformer components and specialty materials
Environmental compliance requirements associated with transformer oil handling and asbestos remediation
