Attachment Appendix A - Convoy Point Work Area Map and Legend (Areas 1-9)

1. BACKGROUND

Biscayne National Park is located approximately 20 miles south of Miami in Homestead, Florida. The park protects the northernmost group of living coral reefs in the continental United States and associated coastal and marine ecosystems. More than 95 percent of the park is water and is accessible primarily by boat. Convoy Point is the park's primary mainland visitor and administrative area.

Trees, palms, mangroves, and other woody vegetation at Convoy Point require pruning to correct prior improper cuts, reduce dead or conflicting branches, improve structural condition and wind resistance, maintain clearances, and restore selected views while protecting park resources.

2. OBJECTIVE

The National Park Service (NPS) requires a qualified tree-care contractor to furnish all supervision, labor, equipment, tools, materials, transportation, and incidentals necessary to perform the pruning and related vegetation-management work described in this SOW and Appendix A. The work shall reduce hazardous conditions and excessive wind loading, improve tree and palm structure, provide required building/sign/light/dock clearances, and improve designated vistas without unnecessary damage to trees, mangroves, other vegetation, wildlife, park property, or visitor facilities.

3. PLACE OF PERFORMANCE

Biscayne National Park - Convoy Point 9700 SW 328th Street (Sir Lancelot Jones Way) Homestead, Florida 33033

Appendix A identifies nine numbered work areas at Convoy Point, including visitor center, parking, maintenance, bridge/boardwalk/dock, Headquarters, waterfront, parking, and housing areas. The Appendix A boundary lines establish the general limits of work. Section 7 provides the corresponding functional descriptions and required work. If a conflict exists between the map and the written requirements, the written SOW governs.

Offerors are strongly encouraged to inspect the site during any Government-scheduled site visit to verify access, staging constraints, equipment needs, and the observable quantity and condition of trees, palms, and vegetation within the mapped areas.

4. PERIOD OF PERFORMANCE AND WORK SCHEDULE

1. Complete all contract work within 30 calendar days after award, unless the Contracting Officer changes the period of performance by written contract modification.

2. Normal work hours are Monday through Friday, 7:00 a.m. to 3:30 p.m., during daylight hours. No work shall be performed on weekends or Federal holidays without advance Government approval. Approval to work outside normal hours does not, by itself, extend the period of performance.

Hazardous Tree Work - Biscayne National Park

3. The Contractor shall immediately notify the COR of actual or anticipated schedule delays. Only the Contracting Officer may change contract terms, including the completion date.

4. If the Contractor is unable to work due to site-specific weather conditions, the Contractor shall notify the COR no later than 7:00 a.m. that day. Weather conditions elsewhere do not, by themselves, establish that the Convoy Point site is unsuitable for work.

5. Tropical storms and hurricanes: When directed by NPS, the Contractor shall suspend operations and secure or remove equipment, debris, materials, and other items that could become hazards. NPS may direct shutdown approximately 72 to 48 hours before anticipated landfall or earlier if conditions warrant. Work shall resume only after NPS authorizes re-entry and site operations.

5. SCOPE AND GENERAL PERFORMANCE REQUIREMENTS

6. Furnish all labor, supervision, equipment, tools, materials, supplies, transportation, and incidentals necessary to complete the work. Unless expressly identified as Government-furnished, all items required for performance are the Contractor's responsibility.

7. Provide on-site coverage by an ISA Certified Arborist and a superintendent/foreman whenever pruning or cutting operations are being performed. The roles may be performed by the same individual if that person meets the qualifications and responsibilities of both positions. See Section 15, Project Personnel.

8. Perform only the pruning/trimming and related vegetation work described in this SOW. No complete tree removals are included in the base requirement. Whole-tree removal, clearing, grubbing, stump removal, or work outside the mapped areas is not authorized unless separately identified and authorized by the Contracting Officer through a written contract modification.

9. Protect visitors, employees, vehicles, buildings, signs, lights, docks, utilities, pavement, landscaping, and other park property. Establish and maintain work zones, drop zones, barriers, cones, flaggers/spotters, and temporary pedestrian or traffic controls as appropriate for the operation. Coordinate any temporary closure of visitor or staff areas with the COR before implementation.

10. Confine staging, equipment, vehicles, and material storage to locations designated by the COR. Maintain emergency and operational access at all times unless otherwise approved.

11. Remove all Contractor-generated branches, fronds, chips, trash, and other debris from Government property each workday. Disposal shall be off site and in accordance with applicable laws and regulations. No debris shall be dumped, stockpiled overnight, or disposed of on NPS property unless specifically authorized in writing.

12. Notify the COR in advance of scheduled site access to controlled or secured areas and of any change to the approved work schedule.

13. No Contractor advertising signs shall be installed on Government property. Contractor personnel shall wear appropriate work clothing and visible company identification. Smoking and eating are permitted only in areas designated by the park.

6. TECHNICAL STANDARDS AND PRUNING REQUIREMENTS

14. Perform tree, shrub, and palm pruning in accordance with ANSI A300-2023 Tree Care Standards, including Clause 5 (Pruning), and generally accepted arboricultural best management practices. Perform arboricultural operations in accordance with applicable ANSI Z133 safety requirements, OSHA requirements, and other applicable Federal, State, and local requirements.

15. Use pruning methods that preserve natural form and tree health. Topping, indiscriminate shearing of trees, flush cuts, excessive interior stripping ("lion-tailing"), and other practices inconsistent with ANSI A300 are prohibited unless expressly required by this SOW.

16. Primary tree work includes crown thinning, crown raising/clearance pruning, deadwood removal, selective correction of prior stub cuts, and selective removal of crossing or rubbing branches when removal of one branch is appropriate.

17. The principal pruning objective is to reduce excessive crown density and wind loading caused by prior over-lifting and subsequent crown overgrowth while maintaining long-term tree health, structure, and safety.

18. Correct prior stub cuts by making appropriate final pruning cuts consistent with branch collar/branch bark ridge considerations and ANSI A300 practices.

19. Remove dead, broken, or hanging branches within the specified work areas that present a hazard or are part of the required pruning objective.

20. Palms in Areas 1 through 9 shall have dead/dying or broken fronds and seed pods removed and shall be pruned to the specified 9-to-3 profile. Do not perform excessive "hurricane" cuts or remove healthy fronds above the specified pruning profile.

21. Where this SOW requires building, sign, light, dock, or access clearance but does not state a numerical clearance distance, prune only to the extent necessary to eliminate contact or obstruction and provide practical operating clearance while maintaining tree health and natural form. Coordinate unusual conditions with the COR before cutting.

7. WORK AREAS AND AREA-SPECIFIC TASKS

Appendix A identifies Areas 1 through 9 and retains the established work-area boundaries. For purposes of this SOW, the Appendix A map labels and the functional work-area descriptions correspond as shown below. Work is limited to vegetation within the mapped boundaries unless otherwise authorized by the Contracting Officer.

The park does not maintain a formal tree inventory identifying exact counts, species, or heights for every tree and palm in these nine work areas. To provide offerors a reasonable common basis for preparing a firm-fixed-price quotation, NPS provides the following best estimates of the relative tree and palm composition based on staff familiarity with the site and visual field observations. The estimates are approximate and may vary from actual field conditions. Percentages may not total 100 percent because of rounding, mixed vegetation, and the nature of visual estimates.
