4.0 Security

General security requirements and guidance: The security requirements described below apply to all contract personnel (including employees of the prime Contractor (“Contractor”) and all subcontractor employees) supporting the performance requirements of this contract.

The Contractor is responsible for compliance with these security requirements. Questions regarding security matters shall be addressed to the designated Government representative

(e.g., Contracting Officer Representative (COR), Requiring Activity (RA) representative, or

Contracting Officer (if a COR or other RA representative is not appointed)). Contract personnel are critical to the overall security and safety of US Army Corps of Engineers

(USACE) installations, facilities and activities, and security awareness training contributes to those efforts. The Department of Defense (DoD) and Army security training requirements specified below, if applicable, are performance requirements; all applicable contract personnel shall complete initial training within 30 days of contract award or the date new contract personnel begin performance on the contract. Within five business days from the completion of training, the Contractor shall provide written documentation (e.g., email or memorandum) to the Government representative. The documentation shall include the names of contract personnel trained and which training they completed; the Contractor shall maintain training records as part of their contract files and be prepared to provide copies of training certificates to the Government representative. Contractor personnel and vehicles are subject to search when entering federal installations. Additionally, all contract personnel shall comply with Force

Protection Condition (FPCON) measures, Random Antiterrorism Measures (commonly referred to as “RAMs”), and Health Protection Condition (HPCON) measures. The Contractor is responsible for meeting performance requirements during elevated FPCON and/or HPCON levels in accordance with applicable RA plans and procedures—this includes identifying mission essential and non-mission essential personnel. In addition to the changes otherwise authorized by the changes clause of this contract, should the FPCON or HPCON levels at any individual facility or installation change, the Government may implement security changes that affect contract personnel. The Contractor shall ensure all contract personnel are aware of their security responsibilities, including any site-specific requirements identified in local policies or procedures.

Nashville District (LRN) Security Access Form to the Nashville District Point of Contact (LRN

POC) five (5) days prior to the site visit or meeting. If submitting the document in less than five days, the Offeror/Bidder may not receive approval for participation. The LRN POC will notify the Contractor if the request is approval or denied. Any pre-bid meeting which will cover anything other than public domain information shall be limited to US Citizens, except under unique circumstances. The Security Access Form and guidance is available at https://www.lrd.usace.army.mil/Submit-ArticleCS/Programs/Article/3667149/contracting/

Contractor is expected to prescreen their own job applicants for suitable candidates before submission to the U.S. Government. The U.S. Government will not screen potential candidates for you. Once the contractor has selected suitable employees to work on a government site, the contractor will submit them for processing as outlines above. Submission to the district security office must be accomplished prior to a contract employee’s site access.

ACCESS NOT AUTHORIZED for any federal property nor to begin work on any part of the contract until investigation requirements have been met/completed and notification has been made by the COR or the District Security Office. There is no blanket approval, no waivers, no exceptions. Each contractor employee is a case-by-case screening process. Preliminary results may require additional screening requirements before site access approval can be provided.

Suspicious Activity Reporting training (e.g. iWATCH, CorpsWatch, or See Something, Say Something): All contract personnel shall receive initial and annual refresher training from the RA representative on the local suspicious activity reporting program. This locally developed training provides contract personnel with general information on suspicious behavior, and guidance on reporting suspicious activity to the project manager, security representative or law enforcement entity.

Escorting in classified and/or sensitive areas For LRN this applies when a contractor needs access within sensitive or restricted areas (areas off-limits to the public) OR working where he/she could get access to sensitive information (CUI, PII, blueprints/drawings, contract proposals, etc.) Use the Standard Language and Additional Proposed language below.

Standard Language “In accordance with applicable regulations, all contract personnel who do not possess the appropriate security clearance or access privileges will be escorted in areas where they may be exposed to classified information or operations, sensitive information or activities, or restricted areas.” ALSO ADD “Escorts must be USACE employees and never other contractors. Note Escort Requirement will no longer be required once the Contract Representative has been notified a favorable long-term investigation

(Category B3) has been completed. B3 not required for extremely short maintenance or repair contracts in which the contractor will be escorted throughout project completion (under 30 days).”

Pre-screen candidates using E-Verify Program: Contractors shall comply with the requirements set forth in RFO clause 52.222-54 Employment Eligibility Verification and RFO
