• Total Contract Value Breakdown: Offerors must indicate the total dollar value and percentage of work to be performed by large businesses and small businesses, as well as the percentage self-performed by the prime.
• SB Category Breakdown: Offerors must detail the combined dollar value and percentage of work to be performed by each Small Business (SB) category, including:
  • Small Disadvantaged Business (SDB) (5% suggested goal)
  • Woman-Owned Small Business (WOSB) (1% suggested goal)
  • Historically Underutilized Business Zone (HUBZone) (.5% suggested goal)
  • Veteran-Owned Small Business (VOSB) (1% suggested goal)
  • Service-Disabled Veteran-Owned SB (SDVOSB) (.5% suggested goal)
• Prime Offeror and Subcontractor Details: Identification of the Prime Offeror and each planned small business subcontractor, including their UIC/CAGE code, type of supply/services, and anticipated NAICS code.
• Type and Extent of Commitment: Description of the type and duration of commitments to use small business concerns (e.g., written contract, verbal agreement).
• Small Business Utilization Past Performance: Submission of past performance information reflecting the Prime's success in meeting small business commitments for projects, including details on self-performance and subcontracting to small and other than small businesses.

This document is critical for non-small business Offerors to demonstrate their plan for subcontracting to various categories of small businesses. Failure to complete and submit this document accurately may impact proposal evaluation and compliance. Bidders must carefully plan and document their small business utilization strategy to meet the 12% MQR and any suggested goals.

Forms / Attachments / Technical Drawings

This document provides a comprehensive set of final reference drawings and technical specifications for the fabrication, assembly, and installation of mechanical and electrical components at The Dalles Lock and Dam. It specifically details the Main Unit Thrust Bearing Oil Cooler (Right Hand) and the Governor Cabinet systems for Fishwater Units 1 & 2.

• Mechanical Fabrication: Detailed drawings for "Inner Tube" (Part 951-501) and "Outer Tube" (Part 951-502) specifying 90/10 Copper-Nickel tubes (ASTM B111 Alloy C70600) with copper spiral tension-wrapped fins.
• Structural Assemblies: Engineering plans for the Thrust Bearing Oil Cooler assembly, including top and bottom plate assemblies and mounting brackets made from ASTM A36 Carbon Steel.
• Governor System Specifications: Outline drawings and hydraulic schematics for the Woodward Governor Cabinet, including detailed piping connections for air supply, oil discharge, and pump controls.
• Facility Layouts: Plan views and sections of the Station Service Bay, Cable Spreading Room, and Oil Storage Room at various elevations (ranging from EL. 30.0 to EL. 174.5).
• Technical Standards: Specific notes on welding requirements (WPS LAPCO-GTA-M-1-1 or WPS B2.1-1-234-2006), hydrostatic testing (75 PSIG for 60 minutes), and precise material tolerances.

This document is an authoritative reference for vendors bidding on fabrication, machining, or mechanical installation services. It defines the exact material grades, dimensions, and assembly sequences required for the project. Bidders should use these drawings to determine material costs, specialized welding labor requirements, and to understand the spatial constraints for equipment installation within the dam's service bays.

Form / Attachment / Pricing Sheet

This document comprises an index and detailed engineering drawings related to the "The Dalles Lock and Dam Columbia River Powerhouse Oil Accountability" project.
