SCOPE

Purpose A. The purpose of the Tyndall Air Force Base (TAFB) project XLWU 21-8131, Repair Parking Area (Sprung City), is to improve the parking area that is currently shared by the LRS, SFS, CES and CONS within the effort to rebuild Tyndall Air Force Base. Due to the current layout and usage for different zones with the parking area this project will have to be phased to maintain access to the adjacent offices and minimize interruption of productivity. The project will consist of design, reconstruction and repair of the parking area and two driveways, to include all aspects of the design, permitting and construction. The Contactor shall be responsible for all professional services, permits, equipment, labor, tools materials and ancillary items necessary to complete the tasks defined by the SOW. The performed tasks shall be based on the project description, other data furnished in the SOW, and information covered during a pre-construction/criteria review meeting to be held prior to contractor mobilization.

B. The Contractor shall adhere to the following guidance during construction phase(s) of this project: Unified Facilities Criteria (UFC) 3‐250‐01, Pavement Design for Roads and Parking Areas; UFC 3‐250‐03, Standard Practice Manual for Flexible Pavements; UFC 3‐600‐01, Fire Protection for Facilities; United States Army Corps of Engineers; Uniform Building Code (UBC); those sections of the Southern Standard Building Codes not incorporated in the UBC/International Building Code (IBC) for our respective area; Air Force Standards; Department of Defense (DOD) Directives; Florida State Statutes; Florida Department of Transportation (FDOT); the Tyndall AFB Facility Excellence Plan (Base Regulations); 325th Fighter Wing Bird Aircraft Strike Hazard (BASH) Plan 910; National Electric Code (NEC); Occupational Safety and Health Administration (OSHA) Requirements; Department of Environmental Protection (DEP) Regulations; Environmental Protection Agency (EPA) Regulations; and any related Americans with Disabilities Act (ADA) Compliance Requirements. If there is a conflict between these codes, regulations and specifications the most stringent requirements shall apply at all times. Documents listed by and/or provided by the Government are for reference only and do not relieve the Contractor from adherence with applicable codes not specifically addressed.

C. 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 also apply.

D. This task order delivery method is Design-Build (D-B). The Contractor shall be responsible for providing all labor, equipment, tools, materials, and services necessary to complete the project within the allotted timeframe.

E. 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 150 calendar days.

F. Mobilization and implementation of site prep work may begin after the 95% Design has been approved. Ordering of long lead items may be coordinated with CO.

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. 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.

C. Quantities and Measurements: All quantities and measurements are approximations or summaries and the contractor is responsible for verification during the development of the proposal.

D. The parking area will meet ADA and ABA standards.

Summary of Work

The priorities of this project are design, reconstruction and repair of parking areas to support a shared usage by the LRS, CES, SFS and CONS sections. The project area is approximately 164,000 square feet (SF) and is to include all aspects of design, permitting and reconstruction and repair of the parking lot to consist of as necessary: reconstruction, asphalt and striping. Parking areas will utilize the locations outlined in Appendix B. Traffic patterns and possible phasing may require entrance and exit onto Mississippi Road and Suwannee Avenue. The existing asphalt driveway connecting to Suwannee Avenue needs to be widened to the standard width (24 feet minimum) to match the other driveways on base and the current gravel driveway to the east shall be constructed into a second asphalt connection. Personnel and traffic that usually park in this area will have to be accommodated with parking elsewhere during the phased construction process. The western portion of the parking area, where parking currently takes place, is to be reconstructed and restriped. It shall be sloped in a way that allows the storm water runoff to be conveyed off the asphalt and as much as possible the existing storm water ditch, to minimize puddling/bird baths.

The north-eastern portion of the parking area is to spot repaired, as needed, per all the existing damage due to trenching and lack of maintenance, examples shown in Appendix B. The remaining areas in and around the sprungs, in their current layout also required spot repair due to the same issues of utility installation damage and pot holes. These areas shall be repaired to ADA compliancy at a minimum with no trip hazards. These areas must be safe for pedestrians and completed with results that do not allow runoff to collect in spots.

The existing multi-use pathway located along the south-western side of the parking area is currently in a highly deteriorated condition and will be removed and included in the parking lot reconstruction.

Task 1.0: Reconstructing Parking Areas

1.

2.

Design & Permitting

The parking area shall be designed to maximize the quantity of parking spaces that can fit within the space available. The image provided in Appendix B shows 81 parking spaces, however the designer may propose a revised layout option to be considered that fits within the rules and regulations that cover pavement design. The proposed striped area at the west side of the parking lot has layout restrictions, therefore the layout shown in appendix B cannot be revised with much flexibility. It is the contractor’s responsibility to verify the requirement of any and all permits for the approved project activities.

Striped Parking Area

This existing parking area shall have the existing asphalt pavement, base materials and excess soils removed. The reconstruction of this area will be sloped in a way that allows storm water runoff to be conveyed into the storm water management system and surrounding grassy areas. The following general requirements shall be met during construction:

A. Remove existing asphalt pavement, base materials, and excess soils.

B. Compact subgrade to 95% Modified Proctor value.

C. Install 8 inches limerock base compacted to 98% Modified Proctor value.

D. Install 2.5 inches SP12.5 asphalt pavement with standard cross slopes (crown) to shed water.

E. Paint new reflective pavement markings.

Non-Striped Parking Area

This existing asphalt area shall be spot repaired to correct damaged locations around this portion of the parking area in a way that does not inhibit the work activities within the LRS area of operation. This location shall also be sloped in a way that conveys storm water runoff away from the structures within into the abutting grassy area. This area may be fenced off to restrict access to the sprungs before or during construction. The project shall progress as planned and any issues shall be announced to all necessary parties as soon as possible to ensure no subsequent issues occur and project activities may commence expeditiously.

Striping

Striping of site will include all markings necessary to allow vehicles parking access in the designated areas. Standard striping is required within the selected parking area to maintain regular flow of traffic. Striping will also be required at the newly paved driveways as needed for entering the Suwanee Avenue right-of-way (ROW).

Signage

Contractor shall install the required signage for pedestrian crossing and parking stalls set for ADA compliance. If any additional signage is necessary it will be submitted for base approval.

Best Management Practices (BMPs)

The contractor shall provide/install measures that control erosion connected to construction activities. Methods and procedures will also be in place that prevent the transfer of sediment to the adjacent roadway, into the Sprungs/buildings on site, or into the existing storm water management system. There will be daily and post storm event inspections of all erosion and sediment control measures in place by the site supervisor or qualified employee. These measures are to be restored back to a functioning status immediately to secure the site during construction. The contractor must report any major incidents and take action without delay to minimize any environmental impact.

These control measures must be in accordance with the criteria noted in UFC 3-201-01, UFC 3-210-10, HDS-5, or the state drainage manual; whichever is more stringent. Ensure that the storm water runoff does not adversely affect surrounding sites.

Task 2.0: Driveway Reconstruction

Pavement Access Way Expansion

The existing asphalt driveway has some normal wear and tear and width issues that require its removal and reconstruction. The existing type-D curbing will also be removed on both sides to allow storm water run-off to flow onto grassed areas on both sides of the driveway. The new driveway shall be sloped to keep run-off on-site and not allow run-off from Suwannee Avenue to enter the site. The new driveway will also be a minimum width of 24-feet. The following general requirements shall be met during construction:

A. Remove 12 inches of existing soils and base materials.

B. Compact subgrade to 95% Modified Proctor value.

C. Install 8 inches limerock base compacted to 98% Modified Proctor value.

D. Install 2.5 inches SP12.5 asphalt pavement with standard cross slopes (crown) to shed water

Gravel to Asphalt Access Way Improvement

The existing gravel driveway located on the east side of the site is not officially connected to Suwannee Avenue. The Type-F curbing will have to be altered to allow the new asphalt driveway to smoothly transition down to that actual edge of pavement (EOP). The new driveway will be a minimum width of 24-feet and sloped to displace storm water runoff while disallowing any to enter or leave the site. The following general requirements shall be met during construction:

A. Remove 12 inches of existing gravel, soils and base materials.

B. Compact subgrade to 95% Modified Proctor value.

C. Install 8 inches limerock base compacted to 98% Modified Proctor value.

D. Install 2.5 inches SP12.5 asphalt pavement with standard cross slopes (crown) to shed water.

Task 3.0: Spaces between and around the Sprung Structures

The remaining zones between the sprung structures, around the storage containers and vaults shall be repaired to ADA compliancy at a minimum. This area has a lot of trip hazards and trenching damage that could potentially lead to greater damage if left as is. This area shall be effectively patched and sealed in locations that machinery cannot reach due to close proximity of the existing structures. The open areas will be milled, repaired (as needed) and resurfaced in areas where the machinery is able to traverse. The area should be reconstructed in a way that would allow storm water runoff to not collect in areas on the pad and minimize any puddling.

POINTS OF CONTACT (POCs)

POCs will be coordinated through the CO.
