Security:

AT/OPSEC Form 6055 contract paragraph requirements are as follows:

Block 1: 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) supporƟng the performance requirements of this contract. The Contractor is responsible for compliance with these security requirements.

QuesƟons regarding security maƩers shall be addressed to the designated Government representaƟve (e.g., ContracƟng Officer RepresentaƟve (COR), Requiring AcƟvity (RA) representaƟve, or ContracƟng Officer (if a COR or other RA representaƟve is not appointed)).

Contract personnel are criƟcal to the overall security and safety of US Army Corps of Engineers (USACE) installaƟons, faciliƟes and acƟviƟes, 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 iniƟal training within 30 days of contract award or the date new contract personnel begin performance on the contract. Within five business days from the compleƟon of training, the Contractor shall provide wriƩen documentaƟon (e.g., email or memorandum) to the Government representaƟve. The documentaƟon 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 cerƟficates to the Government representaƟve. Contractor personnel and vehicles are subject to search when entering federal installaƟons. AddiƟonally, all contract personnel shall comply with Force ProtecƟon CondiƟon (FPCON) measures, Random AnƟterrorism Measures (commonly referred to as “RAMs”), and Health ProtecƟon CondiƟon (HPCON) measures. The Contractor is responsible for meeƟng performance requirements during elevated FPCON and/or HPCON levels in accordance with applicable RA plans and procedures—this includes idenƟfying mission essenƟal and non-mission essenƟal personnel. In addiƟon to the changes otherwise authorized by the changes clause of this contract, should the FPCON or HPCON levels at any individual facility or installaƟon change, the Government may implement security changes that affect contract personnel. The Contractor shall ensure all contract personnel are aware of their security responsibiliƟes, including any site-specific requirements idenƟfied in local policies or procedures.

Block 3: Physical security and access control requirements: All contract personnel requiring physical access to a federal installaƟon or facility shall comply with the access control procedures of that locaƟon. Contract personnel requiring unescorted access to meet contract performance requirements on DoD property in the US shall be veƩed by the District Security Office using the NaƟonal Crime database and Terrorist Screening Database. Contract personnel shall comply with all personal idenƟty verificaƟon requirements specified in facility policies and procedures. Contract personnel who do not meet requirements for unescorted access to USACE faciliƟes shall coordinate escorted access with the Government representaƟve, as needed.

Contract personnel who receive keys, access cards, or lock combinaƟons that provide access to government-owned property shall comply with key and lock control procedures of the RA.

Since the work is being done within a controlled area but is expected to last less than six months, the invesƟgaƟon requirements fall under Category B1 for US CiƟzens and Category C for Foreign NaƟonals. Contract employees will need to be supervised/ escorted by a Corps employee while within the restricted area. In the event it is determined the contract will extend beyond six months, the contractor will need to comply with the requirements in Category B2 for US CiƟzens. Guidance and forms for the requirements are available on the Nashville District Public Website:

hƩps://www.lrd.usace.army.mil/Submit-ArƟcleCS/Programs/ArƟcle/3667149/contracƟng/

Contract and sub-contract employees are not authorized to begin work on any contract unƟl invesƟgaƟon requirements have been completed and noƟficaƟon has been made by the COR or the District Security Office.

Because the work is being performed in a restricted area, there are restricƟons on use of persons either imprisoned or previously convicted of a felony. The Contractor shall not employ in the performance of this contract any person undergoing a sentence of imprisonment imposed by any court of a State, the District of Columbia, Puerto Rico, the Northern Mariana Islands, American Samoa, Guam, or the U.S. Virgin Islands, or the US Federal Government. The Contractor shall not employ in the performance of this contract any person who has been convicted of a felony imposed by any court of a State, the District of Columbia, Puerto Rico, the Northern Mariana Islands, American Samoa, Guam, the U.S. Virgin Islands, or the US Federal Government.

Contractors and/or potenƟal contractors wishing to aƩend a pre-bid meeƟng held at or in LRN restricted/controlled areas (such as a Power Plant or NavigaƟon Lock) shall submit a Nashville District (LRN) Security Access Form to the Nashville District Point of Contact (LRN POC) five (5) days prior to the site visit or meeƟng. If submiƫng the document in less than five days, the Offeror/Bidder may not receive approval for parƟcipaƟon. The LRN POC will noƟfy the Contractor if the request is approval or denied. Any pre-bid meeƟng which will cover anything other than public domain informaƟon shall be limited to US CiƟzens, except under unique circumstances. The Security Access Form and guidance is available at hƩps://www.lrd.usace.army.mil/Submit-ArƟcleCS/Programs/ArƟcle/3667149/contracƟng/

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 potenƟal 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 unƟl invesƟgaƟon requirements have been met/completed and noƟficaƟon has been made by the COR or the District Security Office. There is no blanket approval, no waivers, no excepƟons.

Each contractor employee is a case-by-case screening process. Preliminary results may require addiƟonal screening requirements before site access approval can be provided.

Block 6: Suspicious AcƟvity ReporƟng training (e.g. iWATCH, CorpsWatch, or See Something, Say Something): All contract personnel shall receive iniƟal and annual refresher training from the RA representaƟve on the local suspicious acƟvity reporƟng program. This locally developed training provides contract personnel with general informaƟon on suspicious behavior, and guidance on reporƟng suspicious acƟvity to the project manager, security representaƟve or law enforcement enƟty.

Block 14: Pre-screen candidates using E-Verify Program: Contractors shall comply with the requirements set forth in FAR clause 52.222-54 Employment Eligibility VerificaƟon and FAR Subpart 22.18 in using the E-Verify Program at (hƩps://www.e-verify.gov/) (website subject to change) to meet the contract employment eligibility requirements. Contractors are encouraged to cooperate with Federal and State agencies responsible for enforcing labor requirements to include eligibility for employment under United States immigraƟon laws in accordance with FAR 22.102-1(i). An iniƟal list of verified/eligible candidates shall be provided to the COR no later than three business days aŌer the iniƟal contract award. When contracts are with individuals, the individuals will be required to complete a Form I-9, Employment Eligibility VerificaƟon, and submit it to the ContracƟng Officer to become part of the official contract file.

All contract employees and subcontractors shall always conduct themselves in a proper manner.

No alcoholic or intoxicaƟng beverages or substances or illegal drugs or controlled substances not prescribed by a physician shall be possessed, consumed, or be under the influence of any such substance while on Government property.

The Contractor shall remove from the site any individual whose conƟnued employment is deemed by the appointed receiving agent to be contrary to the public interest or inconsistent with the best interests of the U.S. Army Corps of Engineers.

The ContracƟng Officer or the appointed receiving agent will require the Contractor to immediately remove from the work site anyone who is incompetent or who endangers persons or property or whose physical or mental condiƟon is such that it would impair the employee’s ability to saƟsfactorily perform the work. NoƟficaƟon to the Contractor will be made in wriƟng if Ɵme and circumstances permit. Otherwise, noƟficaƟon will be verbal and will be confirmed in wriƟng as soon as possible. No such removal, however, will reduce the Contractor's obligaƟon to perform all work required under this contract and immediate replacement shall be made as required.

The Contractor is responsible for taking the acƟon necessary to protect Contractor supplies, materials and equipment, and the personal property of Contractor employees from loss, damage, or theŌ. The Government assumes no responsibility for theŌ, damage, etc., of the above. All incidents of theŌ (or suspected theŌ) of contractor materials, supplies, or equipment from project lands shall be reported to the COR.
