The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items necessary to safely remove Eighteen (18) pine trees affected by pine beetle infestation and any incidental work as defined in this PWS. Each tree will need to be completely removed with minimal damage to park natural and cultural resources. The contractor shall perform to the standards in this contract. All debris from tree removal will be disposed of outside the boundaries of Fort Frederica National Monument in accordance with Georgia Forestry Commission and Georgia Environmental Protection Division.

Work shall be performed in and around the Townsite of Fort Frederica National Monument.

6515 Frederica Road, St. Simons Island, GA 31552

All affected trees within the park boundaries will need to be removed. To prevent the accumulation of fuel load the contractor shall remove the entire tree.

Contractor is encouraged to operate under a hazardous tree service license or have a certified arborist on staff. Assign competent climbing crews familiar with standard safety practices IAW accepted industry standards and familiar with the technical aspects and hazards of tree maintenance work and equipment used in such operations.

All work around power lines shall be performed by Certified Line Clearance Tree Trimmers IAW OSHA 229 CF 1910.269, 1910.331 and ANSI Z133.1-1994.

EQUIPMENT REQUIREMENTS: All equipment must meet all federal, OSHA, state and local safety requirements and must be properly licensed. This includes equipment such as bucket trucks, aerial lifts, chipper trucks, wood trucks, etc. which may be needed to correctly perform tree pruning and removal IAW the specifications stated herein.

In instances where the contractor finds pre-existing damage to Park resources which may reflect upon the quality of their work or cause them undue liability, the contractor shall immediately notify the contracting officer’s representative (COR) and the Contracting Officer (CO) of pre-existing conditions.

The contractor shall not start work until the contractor and Contracting Officer (CO) have agreed on the responsibility for these pre-existing conditions.

Identification of areas where trees and/or fuel load removal required are identified on the map provided by the National Park Service, hereafter referred to as the US Government (USG). The map provided should be used as a reference tool, but should not be considered “exact” as many areas requiring treatment will be in clusters or groups of trees. The map in this particular project encompasses all park boundaries to mitigate hazards.

The COR will be responsible for acting on behalf of the CO on all matters of work within the scope of the contract. Approval of work beyond the scope of the contract is reserved for the CO. The contractor is responsible for notifying the COR in writing of any and all work that is beyond the scope of the contract.

Upon request, the contractor shall include a proposal for performing the prescribed work that includes a complete cost breakdown with unit prices for labor, materials, equipment, supervision and oversight to complete the work. The COR will evaluate the proposal and, if valid will seek approval from the CO. Failure of the contractor to obtain the approval of the CO for work beyond the scope of the contract will release the USG from any obligation to pay for services claimed.

Each work area shall be easily identifiable and appropriate barrier protection installed to keep the public safe. The park will allow wood chips to remain in designated areas for stockpile. All other debris shall be removed from the site at the end of each work week or prior to moving on to another work area. Each work area shall be clean and free of debris before moving on to another location.

Work Hours: Work will be performed between the hours of 7:00 a.m. and 4:30 p.m., Monday through Friday, Federal holidays excluded, unless otherwise authorized in writing by the COR

Upon commencement of work, the contractor is expected to be on the job site each day in which weather conditions are favorable as determined by the COR.

All operations shall be conducted IAW ANSI Z133.1-2000 Safety Requirements for Pruning, Trimming, Repairing, Maintaining and Removing Trees and Cutting Brush and all federal OSHA, state and local safety requirements.

Contractor and staff shall wear appropriate personal protective equipment in the performance of work as well as additional safety equipment as necessary (i.e. reflective safety vests while conducting operations in or adjacent to roadways).

No one except the operator shall be within 10 feet of a power saw (specifically park staff and visitors).

All work within a designated area as specified shall be completed, inspected, and accepted by the COR before commencement of work in another area.

If, at any time, the COR determines that the work is unsatisfactory or being conducted in an unsafe manner, the contractor will be notified and shall immediately cease all work activities.

All public roadways shall remain open to the public unless a closure is approved by the COR. The public roadways shall not be encumbered or any unusual traffic situations created by reason of operations under this contract without written approval of the COR.

All Park roads and trails within 30 feet of work shall be barricaded off with danger signs posted. In the event a visitor has trespassed the barricade, work must stop immediately and the work area cleared before continuing with removal.

The Contractor shall not permit heavy equipment or vehicles or the stock piling of heavy materials off hard surface roads without the expressed written permission of the COR. Limited activity may take place within the root protection area with the expressed written permission of the COR in areas determined to be safe from excessive damage. The root protection area is defined as an area equal to a radius of 1.5 feet for each inch of diameter at breast height (dbh) (i.e., a 10 inch dbh tree will have a root protection area equal to 15 feet from the main trunk in all directions). All damage resulting from such operations shall be repaired to its original condition or to the satisfaction of the COR at no additional cost to the USG.

DEFINITIONS:

Diameter at Breast Height (DBH) - The DBH shall be the trunk diameter measured at a point 4.5 feet above the average ground level. Where the trunk divides into several smaller trunks at a point lower than 4.5 feet from the ground, the tree size shall be the diameter measured at the highest point on the single trunk. If a tree falls between sizes as listed in the bid schedule the tree shall be placed in the next larger size (ie: a 17 1/2 inch diameter tree shall be placed in the 18-23 inch size).

Diameter of Crown - The diameter of the crown shall be determined by taking the average of two diameter measurements of the drip line at right angles.

Branch - A secondary shoot or stem arising from one of the main axes (i.e.: trunk or leader) of a tree.

Crotch - The angle formed at the attachment between a branch and another branch, leader, or trunk of a tree.

Crown - The upper portion of a tree from the lowest branch on the trunk to the top.

Lateral - A branch or twig growing from a parent branch or stem.

Leader - A dominant upright stem, usually the main trunk.

Parent Branch or Stem - The tree trunk; or a large limb from which lateral branches grow.

Scaffold - A limb that is or will be part of the permanent branch structure.

Tree Caliper Measurement: The caliper measurement will be determined by taking the average of two trunk caliper measurements at right angles 6 inches above the ground up to and including 4-inch caliper size, and 12 inches above the ground for larger sizes.

Tree Height Measurement: The tree height shall be measured from the ground line to where the main part of the plant ends, not to the tip of a thin shoot.
