1.0 SCOPE

1.1 Purpose

A. The purpose of the Tyndall Air Force Base (TAFB) project XLWU 20-4016, Building 15 and 29 Consolidation, is to repair/upgrade hurricane damage GATR facilities by constructing a new building in B15 area for full 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.

B. The scope of work is based on HVHZ FBC, section 1602.2 criteria for Miami Dade County Risk Category III Buildings and Structures meeting 165 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 Category III. RC III 165 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, 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 the new buildings and support structures since it is designated as a normally unoccupied space and must meet the requirements for a 165 mph wind speed. Support structures include but are not limited to porches, awnings, canopies, etc. The building envelope is required to be built to those standards at this time. The repairs and new installation work must meet all current codes and standards.

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 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 210 calendar days.

H. Implementation of work will not start until an approved 100% Design has been issued. Ordering of long lead items may be coordinated with CO.

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 General:

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: A Survey for asbestos, mold and lead paint should be conducted prior to any demolition or rehabilitation, though demolition is not expected to be a part of this project.

C. Ancillary Task: The tasks in this scope of work do not describe all the ancillary tasks required to complete the task. The contractor is required to complete all ancillary tasks to meet codes and standards that results in a complete and useable facility. Any task omissions by the contractor in their proposal will be the responsibility of the contractor.

D. Quantities and Measurements: All quantities, square footage, linear footage, etc. are estimate to assist contractor in determining scale and scope of this project. Contractor is responsible to verifying and calculating his own quantities for his proposal and estimates do not relieve contractor from providing required quantities and cost to successfully complete project. For example measurements for drywall and painting is a square footage for the room versus the actual wall square footage. Contractor shall provide all calculations, and quantities for government review/approval.

E. The building is being made to ADA or ABA standards.

F. The Fire Protection is being made to meet current standards.

G. Available drawings can be provided upon request.

1.3.1 Exterior Windows, Curtain Walls, Storefronts, Doors, and Louvers Architectural Design Criteria:
