Value Engineering Statement: Contractors are encouraged to draw on their special 'know-how' and experience to propose changes that cut costs while maintaining or enhancing quality, value, and functional performance. You will be required to provide samples of any material(s) you propose as a better value substitute. Otherwise, the specific materials described in this document will be required.

Access and General Protection/Security Policy and Procedures. Contractor employees with an area of performance within Will Rogers Air National Guard Base shall comply with the following. The contractor shall comply with all applicable installation/facility access and local security policies and procedures, which may be obtained from the Contracting Officer’s Representative (COR). The contractor shall also provide all information required for background checks to meet installation access requirements to be accomplished by the local installation’s Security Forces, Badging Office. The contractor shall ensure compliance with all personal identity verification requirements as directed by DoD, HAF and/or local policy. Should the Force Protection Condition (FPCON) change, the Government may require changes in contractor security matters or processes.

For Contractors that do not require CAC, but require access to a DoD Facility and/or

Installation. Contractor and all associated sub-contractors employees shall comply with adjudication standards and procedures using the National Crime Information Center Interstate Identification Index (NCIC-III) and Terrorist Screening Database (TSDB) (AFI 31-101 and AFI 10-245), applicable installation, facility and area commander installation/facility access and local security policies and procedures (provided by government representative), or, at OCONUS locations, in accordance with status of forces agreements and other theater regulations. Contractors will work with the base engineering shop and Security Forces to obtain badging for the base.

Task List: Repair Roofs on building Base wide as indicated on each building and described below. All repairs are to be done in accordance with “UFC 3-110-03 Roofing, with change 5”.

This UFC can be found at the Whole Building Design Guide website “wbdg.org”.
