a. A full body harness with 100% fall protection is required at all times when working 6 feet above a lower level.

b. Fall protection is required when working on roofs within 15ft of a non-roofing operation.

c. Anchor points used for fall protection shall be capable of supporting a 5,000lb load.

d. Provide training certification for all personnel working at heights.

9. SDS sheets shall be available on site for all chemicals brought and/or used on site.

10. Contractor shall provide a simple lift plan to identify the system and components to be used in the lift, the expected total weights, and the placement of the equipment.

11. Prior to the start of any hauling or dumping operations, the contractor shall provide a spotter to avoid any overhead lines or other obstacles.

Period of Performance

Argonne desires for work to be completed by September 30, 2025, but requests the contractor propose their best schedule.

Objectives The objective of this project is to restore several DOE ARM satellite facilities to their natural condition or as requested by the Landowner. While the individual sites are similar, the

Contractor must recognize and understand the differences at each site before submitting a bid.

For instance, at some sites, radars have already been removed, so only site remediation is required. At another site, earth has been displaced to level a fenced-in area, and the Landowner wishes for this to be restored.

Applicable Documents

• Radar installation manual to help guide the dismantling of the radars in reverse order

• Site Drawings and Pictures

• Specification Matrix

Site Specific Tasks

IF4 and IF5

Radar Contractor shall disassemble, remove, and recycle/destroy the X-band radar components (Dome, dish, base, and pedestal) at both sites. The dome is in sections bolted together and then sealed with silicone and may be difficult to separate. Because the components are to be recycled/destroyed, the contractor may remove them in the most economical way possible.

Remediation Contractor shall perform the following:

Structures

• Disassemble and dispose of a 40’ communication towers at both sites. Communications equipment on the towers shall be retained by SGP Personnel.

• Disassemble and remove an 8.5’ x 9’ fiber glass electronics enclosure including the metal instrument rack inside.

• Disassemble and dispose of the steel radar platform.

• Remove and dispose of the 50’ aluminum flagpoles.

Note: Removal of all wiring and computer systems associated with the radars shall be done by

SGP personnel prior to removal of any structures.

APPENDIX B – SOW for ARM SGP IF Site Remediation Page 6 of 7

Underground Electrical

• Remove wire inside of underground conduit from the service disconnect to the radar building and cut off the conduit 24” below the surface and abandon remaining conduit in place.

• Remove all buried grounding circuits and communication lines within the sites.

Civil

• Remove communication towers concrete foundation pads – 90” x 90” x 66” deep

• Remove flagpole foundation pads, 48” x 48” x 68” deep

• Remove radar foundation pads (includes the electronics enclosure foundation), see Radar

Note: Pipe (swing) driveway entrance gates for each site shall remain in place.

IF7

Radar Contractor shall disassemble, remove, and recycle/destroy the C-band radar components. The dome is in sections sealed with silicone and may be difficult to separate. Because the components are to be recycled/destroyed, the contractor may remove in the most economical way possible.

Note: Removal of all wiring and computer systems associated with the radars shall be done by

SGP personnel prior to removal of any structures.

Remediation – Remains in Place No Site remediation at IF7.

IF8 and IF10

• Remove wire inside of underground conduit from the service disconnect to the radar building and cut off the conduit 24” below the surface and abandon remaining conduit in place.

• Remove and dispose of all buried grounding circuits and communication lines within the sites.

Civil Remove and dispose of the following foundations:

• Communications tower pads, 72”x72”x48” deep

• Electronics Enclosure pads, 168”x132”x24” deep

• Radar pad, 168”x168”x24” deep

• All site gravel within the fence line

Note: There are no pip entrance gates at IF4&5

Earth Work At the IF8 site, the Contractor is obligated to perform earth-moving activities to facilitate agricultural operations by the Landowner. The grading must be executed in a manner that permits the use of a mower, bushhog, or other farming equipment necessary for the regular maintenance of rotating crops. Pictures of the

IF8 site are provided with this scope, and all prospective bidders shall be afforded the opportunity to conduct an on-site inspection. Following the site visit, a Request for Information (RFI) period will be available prior to the submission of bids.
