TECHNICAL SPECIFICATIONS

McNary LOCK AND DAM

STATION SERVICE AIR COMPRESSORS - REPLACEMENT

Intent The following specifications pertain to the purchase of three (3) Oil-Lubricated Rotary Screw Air Compressor Assemblies. Two air compressor assemblies will directly replace the existing two station service air compressors that supply 125psig air throughout the entire powerhouse for plant operations and maintenance. McNary mechanical and electrical staff will remove the existing air compressors and install the new air compressors. The existing air piping, air dryers, and electrical service will remain in place. The new air compressor assemblies must be able to be installed into the existing space without alternation to the existing air compression system. The third air compressor assembly will be stored as a new spare for the powerhouse compressed air system. Fiscal Year (FY) 2026 Small Cap Hydro funding will be used to fund this supply purchase. Items listed under 3.0 Specifications are critical. McNary project will retain the current air compressors as project spares.

Scope The Contractor will deliver the three (3) new Oil-Lubricated Rotary Screw Air Compressor Assemblies to McNary Dam by the date shown in Section Shipment and Delivery. The Contractor must provide the required documentation and other items as stated in the specifications. All materials must conform to the “Buy American Act”. To ensure continued operation and efficient maintenance of the selected air compressor assemblies, the assemblies must be able to use replacement parts that are not proprietary to the air compressor manufacturer. NEC and ASME standards must always be followed.

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.
