The personnel having RA Badges can escort up to 10 other contractor/sub-contractors (each) into the RA. A minimum of two is recommended so that one escort can stay with the crew at the project site while a second escort can assist with escorting concrete and asphalt trucks into the RA. All other workers will be required to get a daily Visitor or “V”-Badge to access the RA. The personnel with the “V”-Badges will need to be with an escort while inside the RA. The Escort RA badges will expire at the completion of the contract. The “V” Badges are the yellow badges that the contractors received at the pre-bid site walk.
