The Program must also describe a plan for a government-approved, photo-bearing badging process administered by the Contractor for identification of contractor and subcontractor employees who don't require access into Security Zones 2, 3 or 4.

1.7.2.1 Security Manager

Appoint an on-site Security Manager to administer the Security Program and be responsible for the Contractor's physical security contractual obligations and coordinating all security activities with the Contracting Officer's Representative. This Security Manager will also be responsible for validating deliveries and subcontractor access onto the worksite. The Security Manager must maintain a continuous log of workmen and visitors entering the site and make available to the Government on request. The Security Manager will be equipped to be in radio or cell phone contact at all times. The minimum qualifications for the Security Manager are that the Security Manager meet the requirements and be properly badged for a Zone 4 access. The Security Manager may have other duties.

In so far as is practicable, complete the required PIV-ID paperwork, fingerprinting and security training process as soon as possible before their anticipated start work date in Security Zone 4 areas so as not to impact scheduled work. A red contractor picture badge marked for unescorted access and/or escort privileges to Security Zone 4 will be issued upon receiving clearance. An interim Unescorted Access badge may be granted after the Safety and Security Office receives the results of a preliminary criminal records check contingent upon final adjudication of the background investigation.

(2) Escorted Access: Other contractor personnel may enter Security Zone 4 if they have been issued a red contractor badge or a daily visitor's badge, and are escorted by an approved escort (person with Unescorted Access badges marked "escort"). Escorted personnel do not require a background check.
