4. NOTES

4.1 Pier Restrictions. Due to pier weight restrictions, shore-based crane services will not be allowed. For any weight handling, a suitable barge crane may be required. Any barge crane utilized in this project will be provided by the Contractor.

4.2 Base Access Requirements. Access to the Federal Law Enforcement Training Center (FLETC) requires submittal of access forms. The FTC-OSPR-17 and OF306 forms are required for all U.S. citizens. The 17A form is an additional form that is required for all foreign nationals (including naturalized citizens). FLETC requires 10-14 days for processing of applications for U.S. Citizens and up to 30 days for foreign nationals. In general, new contractors are provided with an initial 30-day badge. These 30 days are intended to provide time for the contractor to get fingerprinted and allows the CG time to process fingerprints (which typically takes 2 weeks). It is only after FLETC receives positive fingerprint results that they will provide a "full-badge" (which should last the duration of the contract). If and only if, the contract will last 5 days or less, only a FTC-OSPR-17Z needs to be submitted for each contractor that will need access to the facility. Contractors that will be onsite for longer than 5 days will need to follow the process outlined above.
