Ice Harbor Turbine Maintenance Platform

This federal solicitation package (Solicitation No. W912EF26BA002, March 2026) outlines the engineering design specifications and technical drawings for the fabrication of Turbine Maintenance Platforms (TMP) and Draft Tube Access Platforms (DTAP) at the Ice Harbor Lock and Dam on the Snake River in Washington. Prepared by the U.S. Army Corps of Engineers (USACE) Walla Walla District and the Hydroelectric Design Center, the project provides custom-engineered structural solutions to facilitate maintenance of the dam's turbine units. The technical documentation details structural configurations and design bases for multiple turbine units (Units 1–6). Key deliverables include the Turbine Maintenance Platform, designed to support a total live load capacity of 12,000 lbs with a safety factor of 4, and the Draft Tube Access Platform, engineered for a 25 psf distributed live load. Additionally, the project encompasses a specialized personnel hoist frame (PH) and Blade Access Scaffolding (BAS) custom-tailored for Unit 2 fixed blades and Units 1 and 3. Contractual and fabrication requirements specify that all aluminum construction utilizes Grade 6061-T6, while structural steel must meet ASTM A572 Grade 50 standards and undergo hot-dip galvanization per ASTM A123. Welding must conform to AWS D1.1 and D1.2 standards. The selected contractor is responsible for verifying all control dimensions, generating comprehensive shop drawings for government approval, performing load testing, and fabricating the platforms, while the government will handle the final field installation.

This solicitation (W912EF26BA002) issued by the U.S. Army Corps of Engineers, Walla Walla District, is for the fabrication, delivery, and on-site assembly of turbine maintenance platforms and scaffolding systems for the Ice Harbor Lock and Dam in Burbank, Washington. The project requires a range of deliverables across eleven Contract Line Item Numbers (CLINs), including a turbine maintenance platform, a draft tube access platform with a personnel hoisting system, blade access scaffolding, transportation/storage carts, and prototypes for the pontoon and scaffolding stands. As a firm-fixed-price acquisition set aside for small businesses, the contract dictates strict fabrication and quality standards. The contractor must utilize facilities with certified weld inspectors (CWI/SCWI) and welders qualified under American Welding Society (AWS) D1.1 (steel) and D1.2 (aluminum) standards. Delivery schedules for the various components range from 5 to 19 months after the date of award, with all deliveries shipped FOB Destination to the Ice Harbor facility. The contract incorporates standard Federal Acquisition Regulation (FAR) and Defense FAR Supplement (DFARS) clauses, including provisions for a one-year complex warranty, limitations on subcontracting, and incentives for value engineering.

This document provides a list of supplemental specifications and shop order drawings for Units 4 through 6 at the Ice Harbor Lock and Dam (IHP) hydro-power facility. The list details eleven technical drawings, including floor plans at various elevations (EL. 368.5, 349.5, and 286.00), transverse sections, and stair details for the erection bay. Additionally, it highlights fabrication and assembly designs for the draft tube liner, a 24"x36" mandoor, and the associated draft tube mandoor frame and assembly. These supplemental engineering drawings serve as technical references for contractors bidding on or executing equipment maintenance and structural modifications at the Ice Harbor facility.

This federal contract specification document details the general and supplementary requirements for the Ice Harbor Turbine Maintenance Platform project (W912EF26BA002 / HLDTMP25) issued by the U.S. Army Corps of Engineers (USACE) Walla Walla District. The scope outlines administrative, safety, and logistical protocols. Key provisions include a strong encouragement to hire and train U.S. military veterans. It defines coordination requirements, establishing that post-award meetings—including Pre-Work, CAD coordination (utilizing Autodesk 2023), Pre-Fabrication, and Resident Management System (RMS) orientation—must occur shortly after contract award. Weekly production briefings are mandated to track progress against a cost-loaded Network Analysis Schedule (NAS) managed via Primavera P6 or Microsoft Project 2016. The document specifies project site restrictions at the secured Ice Harbor Lock & Dam. Access requires strict vehicle inspections, personnel checks, and Foreign Visit Requests (FVR) for non-U.S. citizens. Personnel must undergo mandatory online Safe Clearance/HECP Procedure training through Vivid Learning Systems. Furthermore, the contractor must implement Department of Defense Antiterrorism (AT) and Operations Security (OPSEC) measures, including suspicious activity reporting training and E-Verify employment eligibility pre-screening. Finally, the document details comprehensive submittal procedures using ENG Form 4025 via RMS 3.0, distinguishing between Government Approved ("G") and Information Only ("I") classifications to ensure strict quality control throughout the fabrication process.
