IF5: 19223 E. Robertson Rd Garber, OK (36.4911, -97.5939)

IF7: 22245 W. Ferguson Ave, Nardin, OK, (36.7961, -97.4490)

IF8: 18895 W. Highland Ave, Tonkawa, OK (36.4771 -97.4210)

o To contact landowners, please direct questions to the Technical Representative (Patty Campbell) o County Commissioner information can be provided

• Contractor shall communicate with electric company as needed.

Safety Contractor shall comply with all applicable OSHA requirements to include but not limited to the following:

1. Assign and document an ESH representative on a JSA. Argonne boiler plate template JSA will be provided after the award for Contractor to fill out with task specifics. Those tasks not being performed shall be removed.

2. Contractor ESH representative must be physically present at the worksite anytime work is occurring.

3. Contractor’s ESH representative must provide a current OSHA 30-hour safety training in General Industry or Construction certification after award of contract to the Argonne Technical Representative.

4. Contractor’s ESH representative shall provide and document job site safety orientation training to all personnel working at the job site. Signature of orientation of each personnel shall be provided daily on the approved JSA.

5. Contractors ESH representative shall perform daily checks, as applicable, including, but not limited to the following:

6. Contractor ESH representative will be the primary contact to the Argonne Technical Representative and shall provide periodic check-ins and report all incidents.

7. All after-hour work must be approved by Argonne.

8. Contractor shall follow appropriate OSHA standards for fall protection including but not limited to 29 CFR 1926.104, 1926.1053, CFR 1926 Subpart L, and

1926.450 through 454.

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 when using lift equipment 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 (Appendix)
