Summary Scope of Work

Background: The Lower Granite Unit 2 Blade Sleeve Upgrade project is to restore the Unit 2 turbine to the original Kaplan functionality at Lower Granite Lock and Dam. Following multiple turbine blade sleeve failures, oversized static seals were installed on Unit 2, which has continued operating at a fixed blade angle for more than 5 years.

Project Intent: Unit 2 will be completely unstacked for turbine runner disassembly. New blade sleeves and seals will be installed. The failed blade sleeve material is 410 Stainless Steel (410 SS) and the new blade sleeve material will be a martensitic, precipitation hardening stainless steel (17-4 PH SS). Unit 2 work will also include machining O-ring grooves and installing O-rings in various locations, including turbine shaft fasteners and the upper nose cone, to provide dependable hub oil seals. Reassembly will include pressure testing of the turbine hub before installation is complete.

All on-site work shall be performed in accordance with the Corps of Engineers Safety and Health Requirements Manual (EM 385-1-1).

The Contractor will be responsible for establishing and managing an effective on-site Safety and Health program in accordance with EM 385-1-1 that will require the development and submission of a comprehensive project specific Accident Prevention Plan for Government acceptance. In addition, the Contractor will be required to develop and submit for Government acceptance Activity Hazard Analyses for each phase of work and a project specific Fall Protection Plan that comply with EM 385-1-1.

A Site Safety and Health Officer (SSHO) employed by the prime contractor shall be required for each shift of the contractor's on-site operations. The SSHO shall possess a minimum of 5-years of experience in construction safety on similar projects, shall have completed the 30-Hour OSHA Construction Safety training within the last 5-years, and shall have completed at least 24-hours of formal safety training each year for the past 5-years.
