1.0 SCOPE

1.1 Purpose

A. The purpose of the Tyndall Air Force Base (TAFB) project for building 561 is to repair hurricane damage and to rehabilitate the building sufficiently to continue the mission for up to five years until it is being demo ’d. The work scope for the repairs are to be in compliance with current building codes, including the DoD

Building Code, and the portion of the Florida Building Code that contains the

High Velocity Hurricane Zone (HVHZ) provisions. Exceptions will be noted in the body of the document.

B. The scope of work is based on HVHZ FBC, section 1602.2 criteria for Miami

Dade County Risk Category III and IV Buildings and Structures meeting 186 mph. Based upon our AF Structural SME recommendations and in alignment with the SecAF directed Severe Weather Readiness Assessment recommendations, the

Tyndall PMO will use the UFC 3-301-01 and the following Tyndall design wind speeds based upon Risk Categories III-V. RC III 165 mph and RC IV 170 mph

(Risk categories are defined by UFC 03-301-01, Table 2-2).

C. All exterior building envelope materials such as, but not limited to windows, glazing, roofing systems, concrete masonry unit or metal panel walls, and doors shall have a current Miami-Dado Notice of Acceptance (N0A) and installed to

HVHZ standards that match the specified wind requirement. Our construction industry partners shall continue to have the option of submitting test results or drawings sealed by a Professional Engineer stating conformance with HVHZ standards in lieu of materials pre-approved by Miami-Dade County.

D. While we should always use our Unified Facilities Criteria as the basis for all our facilities designs, we will also integrate the best practices from the Florida

Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) into this design guidance to further improve facility resiliency at Tyndall. Other details from the memorandum may apply as well.

E. A Risk Category III is applicable to buildings 561 since it is designated as Vehicle

Repair Center and must meet the requirements for a 165 mph wind speed.

F. This task order delivery method is Design-Build (D-B). Work on supporting facilities includes external building fixtures, building utilities within the Points of

Demarcation (POD) for privatized utilities, and work within the Administration /

Office Building. The Contractor shall be responsible for providing all labor, equipment, tools, materials, and services necessary to complete the project within the allotted timeframe.

G. This project has an estimated period of performance from Notification to Proceed

(NTP) through completion and turnover of the facility back to the Government for mission operations of 330 calendar days.

H. Implementation of work will not start until an approved 100% Design has been issued. Simple tasks not requiring design documents may be authorized by the

PM with CO concurrence with interim conditions and requirements being met.

Ordering of long lead items may be coordinated with PM with CO concurrence.

I. The latest IFC is to be used for color selection to assure base uniformity. Match existing colors as close as possible. Lighter colors are encouraged. Colors will be approved for use on a per building basis.

1.2 Field Changes:

A. Field Changes: The Contractor and the Government may agree to perform a no cost field change. Field changes are made when the change appears to be mutually beneficial to all parties and would not require changing the negotiated items. All field changes must be approved by the CO prior to execution. Only the CO may authorize field changes or deviations from the SOW.

B. Surveys for asbestos, mold and lead paint should be conducted prior demolition or rehabilitation.
