1. Objective The objective of this contract is to plan and execute the move of the Stratospheric Observatory for Infrared Astronomy (SOFIA) Mirror Coater and Ground Support Equipment from the current site in building 703 at the Armstrong Flight Research Center (AFRC) in Palmdale, CA, to Ames Research Center (ARC), Moffett Field, CA. The contract will include dismantling, packaging, transportation, and unloading. Reassembly, installation, activation, and performance testing is not included in this contract. The unloading and storage location at ARC is not yet determined, but will be communicated at least 30 days prior to the move.

must be performed to ensure that any structures, particularly the welded structures within the chamber, are safe or can be braced appropriately for shipment.

j) The contractor shall develop a Relocation Plan to be reviewed prior to the Project Implementation Review. This document shall include the results of the assessment of stability of the mechanical structures for transport, the method proposed to ensure that the electrical connections can be made appropriately during the re-assembly, the plan for bracing, packing and crating the major assembly or sub-assemblies; the plan for dis-assembly and re-assembly, handling of major elements, a critical lift plan (if necessary), and identification and mitigation strategies for risks.

k) The contractor shall prepare all portions of the Mirror Coater System for disassembly.

This includes making safe all pressure lines, pumps, and any other sub-assembly which requires preparation for dismantling and shipment.

l) The contractor shall dismantle and pack for safe transport all sub-assemblies and ground support equipment. The contractor shall protect all components from any contamination in packing or transport that would impair the ability of the Mirror Coater to pump down to the designed vacuum pressures.

m) The contractor shall provide rigging appropriate to transport all large assemblies to ARC.

n) The contractor shall transport all elements of the Mirror Coater System and its ground support equipment to ARC in Moffett Field, CA.

o) The contractor shall unload the Mirror Coater System at ARC at the NASA-specified location. This location shall be provided to the contractor at least 30 days prior to arrival.

p) The entrance door to the AFRC room has approximately 1” of clearance beyond the

Mirror Coater upper lip, which is the largest full diameter part of the vessel, yet not the widest protuberance. The Contractor shall submit a Lift Plan detailing the method by which the Contractor will bring the vessel through this doorway. The Lift Plan is subject to Government approval.

q) The Contractor shall develop the procedure and means by which the Mirror Coater is removed, transported, and unloaded and shall provide the Government with the assessments, and analyses that are used to demonstrate that a safe method of disassembly and manipulation is planned.

r) Equipment in the Mirror Coating Facility (MCF) that uses fluids in their operation are the Leybold mechanical pump and Roots blower assembly, the CVI cryopumps, the Meissner cryo traps and the gaseous Argon delivery system for the glow discharge cleaning sequence. For disassembly, the Contractor shall properly handle components with fluids, which are the Leybold mechanical pump and Roots blower assembly and the CVI cryopumps.

s) The fluid used in the mechanical pumping system is an inorganic synthetic material, one of whose trade names is Fomblin. Under normal conditions, this fluid is non-hazardous to personnel. However, for the protection of the equipment, the Contractor shall insure that the pumps remain in an upright position (as currently installed) during the MCF disassembly, and shipment. This is to avoid fluid migrating to areas that could possibly damage the pumps upon restarting. After removal, the Contractor shall seal the system components to prevent contamination during the move.

t) The two CVI cryopumps and their compressors, as well as the interconnecting braided lines, contain helium at pressures of over 200 psi. Because of the high pressures involved and the specialized nature of cryopumping equipment, both personnel and equipment hazards are present and this equipment shall only be disassembled by those familiar with this type of equipment. After removal, the Contractor shall seal the system components to prevent contamination during the move.

u) The Meissner cryo trap delivery system uses LN2 from portable tanks that is only connected during coating chamber operation, and therefore presents no hazard during disassembly, shipment or re-assembly; however, the Contractor shall seal the system components to prevent contamination during the move.

v) The gaseous Argon delivery system uses a high pressure cylinder that is only connected during coating chamber operation, and therefore presents no hazard, however, the Contractor shall seal the system components to prevent contamination during the move.

w) The Contractor shall provide the Relocation Plan and the completed wiring list information to the Government for review and approval before any disconnections are made. These wire lists, photos and other documents shall be available completely via electronic format. No handwritten documents shall be used.

x) The Contractor shall disconnect AFRC facility electrical equipment and remove all wiring back to the closest breaker panel.

y) The Contractor shall provide clean up at the AFRC facility, patching any penetrations in walls created by the dismantling or extraction of the mirror coater. Any patches made to walls shall preserve the integrity of the firewalls.

z) At the AFRC facility, the contractor shall grind down all protrusions in the floor from existing tie down bolts, patch the floor with a durable material (such as epoxy), and ensure a smooth surface. The Contractor shall protect the facilities in which work is occurring for this project and restore the facility to the original condition in accordance with FAR 52.236-9 and Section I should any damage be done.

aa) The Contractor shall document existing MCF component orientation for parts mounted on the coating chamber and auxiliary equipment so that the removed components can be re-assembled in the exact orientation as they were before removal for shipping. This shall be accomplished by both photographic and physical documentation of the components before removal from the existing system. In addition, a number of components, such as the cryopumps, must be shipped in preferred orientations. The Contractor shall evaluate each component to be moved and document intended handling and packaging means.

How these components are shipped shall be photographed and documented.

bb) The contractor must deliver a Lift Plan for both loading and unloading per Appendix C.

cc) The Contractor shall use air-ride suspension vehicles for transport or identify any Mirror

Coating System equipment that is to be truck-transported by means other than an air-ride suspension equipped truck, along with justification for the appropriateness of alternative means.

4. Period of Performance Site visits may begin after award and are expected to occur in December 2023 or January 2024.

The Mirror Coater move shall be completed no later than March 2024.

The above information shall be documented, and the record made available for inspection. Upon completion of the Lockout/Tagout Operation the documents shall be stored at the jobsite.

NASA will, at the Contractor's request, apply lockout/tagout tags and take other actions that, because of experience and knowledge, are known to be necessary to make the particular equipment safe to work on.

No person, regardless of position or authority, shall operate any switch, valve, or equipment that has an official lockout/tagout tag attached to it, nor shall such tag be removed except as provided in this section.

No person shall work on any equipment that requires a lockout/tagout tag unless he, his immediate supervisor, project leader, or a subordinate has in his possession the stubs of the required lockout/tagout tags.

When work is to be performed on electrical circuits, the contractor shall only allow qualified personnel to perform work on electrical circuits.

A supervisor who is required to enter an area protected by a lockout/tagout tag will be considered a member of the protected group provided he notifies the holder of the tag stub each time he enters and departs from the protected area.

Identification markings on building light and power distribution circuits shall not be relied on for established safe work conditions.

Before clearance will be given on any equipment other than electrical (generally referred to as mechanical apparatus), the apparatus, valves, or systems shall be secured in a passive condition with the appropriate vents, pins, and locks.

Pressurized or vacuum systems shall be vented to relieve differential pressure completely.

Vent valves shall be tagged open during the course of the work.

Where dangerous gas or fluid systems are involved, or in areas where the environment may be oxygen deficient, system or areas shall be purged, ventilated, or otherwise made safe prior to entry.

B.1 Tag Placement

Lockout/tagout tags shall be completed in accordance with the regulations printed on the back thereof and attached to any device which, if operated, could cause an unsafe condition to exist.

If more than one group is to work on any circuit or equipment, the employee in charge of each group shall have a separate set of lockout/tagout tags completed and properly attached.

When it is required that certain equipment be tagged, the Government will review the characteristics of the various systems involved that affect the safety of the operations and the work to be done; take the necessary actions, including voltage and pressure checks, grounding, and venting, to make the system and equipment safe to work on; and apply such lockout/tagout tags to those switches, valves, vents, or other mechanical devices needed to preserve the safety provided. This operation is referred to as "Providing Safety Clearance."

B.2 Tag Removal

When any individual or group has completed its part of the work and is clear of the circuits or equipment, the supervisor, project leader, or individual for whom the equipment was tagged shall turn in his signed lockout/tagout tag stub to NASA. That group's or individual's lockout/tagout tags on equipment may then be removed on authorization by NASA.
