McNary LOCK AND DAM

STATION SERVICE AIR COMPRESSORS - REPLACEMENT

Intent The following specifications pertain to the purchase of three Rogers Machinery Oil-Lubricated Rotary Screw Air Compressor Assemblies. This is a direct replacement for the existing two station service air compressors that supply 125psig air throughout the entire powerhouse. McNary mechanical and electrical staff will remove the existing air compressors and install the new air compressors. The third Rogers Machinery air compressor assembly will be stored as a new spare for the powerhouse compressed air system. FY25 Small Cap Hydro funding will be used. Items listed under 3.0 Specifications are critical. McNary project will retain the used Quincy air compressors as project spares.

Scope The Contractor shall be required to deliver the new Oil-Lubricated Rotary Screw Air Compressor Assemblies to McNary Dam by the date shown in Section Shipment and Delivery. The Contractor shall provide documentation and other items as stated in the specifications.

MOTOR CONTROL

Magnetic X-line starter, 125 HP, 3/60/460 volt, in NEMA 1 enclosure mounted, wired, and tested with the compressor.

CONTROLS

Standard dual control package to allow the compressor to operate in Load/Unload or Low Unloaded Horsepower (LUHP). LUHP allows the user to set the unload point of the compressor based upon the ratio of the demand of the system to the compressor’s capacity (percentage capacity). The unloading setpoint can be tuned to minimize compressor cycling and maximize power savings considering the system’s available storage. Both modes include an adjustable timed shutdown and automatic restart on a pressure signal.

COMPRESSED AIR CAPACITY DISPLAY

Compressed air capacity display shows the percentage of total compressor capacity being used. This feature is particularly useful in determining compressed air leaks and in determining how much capacity remains for future use.

WATER SOLENOID VALVE

Water flow solenoid valve.

Operation Security

· General security requirements and guidance: The security requirements described below apply to all contract personnel (including employees of the prime Contractor ("Contractor") and all subcontractor employees) supporting the performance requirements of this contract. The Contractor is responsible for compliance with these security requirements. Questions regarding security matters shall be addressed to the designated Government representative (e.g., Contracting Officer Representative (COR), Requiring Activity (RA) representative, or Contracting Officer (if a COR or other RA representative is not appointed)). Contract personnel are critical to the overall security and safety of US Army Corps of Engineers (USACE) installations, facilities and activities, and security awareness training contributes to those efforts. The Department of Defense (DOD) and Army security training requirements specified below, if applicable, are performance requirements; all applicable contract personnel shall complete initial training within 30 days of contract award or the date new contract personnel begin performance on the contract. Within five business days from the completion of training, the Contractor shall provide written documentation (e.g., email or memorandum) to the Government representative. The documentation shall include the names of contract personnel trained and which training they completed; the Contractor shall maintain training records as part of their contract files and be prepared to provide copies of training certificates to the Government representative. Contractor personnel and vehicles are subject to search when entering federal installations. Additionally, all contract personnel shall comply with Force Protection Condition (FPCON) measures, Random Antiterrorism Measures (commonly referred to as "RAMs"), and Health Protection Condition (HPCON) measures. The Contractor is responsible for meeting performance requirements during elevated FPCON and/or HPCON levels in accordance with applicable RA plans and procedures --this includes identifying mission essential and non-mission essential personnel. In addition to the changes otherwise authorized by the changes clause of this contract, should the FPCON or HPCON levels at any individual facility or installation change, the Government may implement security changes that affect contract personnel. The Contractor shall ensure all contract personnel are aware of their security responsibilities, including any site-specific requirements identified in local policies or procedures.
