TDA Isolated Phase Bus & Duct Inspection

Statement of Work (SOW) / Performance Work Statement (PWS)

This Performance Work Statement (PWS) outlines the requirements for services to test the condition of the Isolated Phase Bus and Duct System at The Dalles Dam (TDA) in The Dalles, Oregon.

• Online Testing and Inspections: Conduct external visual inspections, infrared (IR) thermal imaging, and electromagnetic interference (EMI) diagnostics on accessible IPB components while carrying near-rated current. This includes examining bus enclosures, grounding, connectors, and identifying overheating or inadequate cooling areas.

• Offline Testing and Inspections: Perform detailed offline condition assessment of IPB systems during scheduled outages. This includes visual inspections of components (bolted connections, ground/bond/isophase jumpers, seal-off bushings), electrical testing (AC High Potential Test, Megger Test, insulation resistance), and a review of the design and rating.

• Asbestos Abatement, Set Up and Tear Down: Abate asbestos-containing material (ACM) from panel door gaskets. Set up and tear down equipment for testing.

• Asbestos Disposal: Dispose of abated ACM off Government Property at approved facilities (not to exceed 150 lbs).

• Work must be performed on schedule and implement safe access controls.

• All associated equipment must be completely removed from the site once work is complete.

• Re-performance is required within 24 hours of notification of non-conformance.

• Documentation of all test results, visual inspection findings, and assessment reports is required.

• Location: The Dalles Dam, The Dalles, Oregon.

• Period of Performance: All work must be completed by April 16, 2027.

• Work Windows: Specific testing and inspection windows are provided for online and offline activities in January 2027 and October-November 2026, respectively.

• Compliance with local, state, and federal regulations, as well as specific standards (e.g., NETA MTS, IEEE C37.23, EM 385-1-1, NFPA 70E).

• Adherence to Hazardous Energy Control Program (HECP) and safety requirements.

• Site visit is highly encouraged.

• Specific security requirements, including training and background checks, apply to all contract personnel.

• Contractor must provide all necessary labor, equipment, and materials. Government may provide mobile crane support.

• Asbestos abatement and disposal must comply with specific regulations.

Form / Attachment / Pricing Sheet

This document is an industry practice comparison survey designed to gather feedback from potential vendors on their experience with similar services in commercial (non-government) projects. The feedback will help the government determine the best acquisition approach for crane drum repair and maintenance work, specifically for isophase bus and duct services.

• Company Practice: Questions about performing similar services for both commercial and government clients.
• Requirement Classification: Asks vendors to classify the requirement as primarily Construction or Commercial Service.
• NAICS Codes: Requests identification of the most relevant NAICS codes.
• Contract Types & Acquisition Approaches: Seeks information on typical contract types and acquisition strategies for similar projects.
• Certifications & Standards: Inquires about specialized certifications, qualifications, or compliance standards.
• Best Practices: Asks for suggestions on structuring contract requirements for safety, quality, and timely restoration.
• Commercial Practice Comparison: For specific requirements (online testing, inspections, surveillance, project coordination, SSHO, CQCM, testing personnel, asbestos abatement), vendors are asked to compare the government's stated requirements against their typical commercial project experiences (Below, At, or Exceeds commercial practice).
• Overall Assessment: A final question asks for an aggregate comparison of the government's requirements to typical commercial projects.

This survey is crucial for potential bidders to provide input that may shape the final acquisition strategy. It allows vendors to directly influence how the government defines and procures the services. Responding to this survey helps bidders share their expertise on commercial practices, which can lead to a more efficient and effective contract structure. The survey also provides insight into the government's current thinking on requirements, allowing bidders to assess their alignment and prepare for potential future solicitations. Responses are due by December 01, 2025, via email to Nicholas.E.Weaver@usace.army.mil and Cory.r.pfenning@usace.army.mil.
