PMIS 189344 Hazard Tree Prevention Project GETT

And other future park tree projects

1.0 OBJECTIVE AND LOCATION

As a result of the Emerald Ash Borer, and normal progression of woodlands, Gettysburg National Military Park has experienced an increase in the number of hazardous trees throughout the park beyond what the park staff can maintain. The intent of this contract is to secure a contractor to remove trees identified by park officials as potentially hazardous.

The trees identified in this contract are on the grounds of Gettysburg National Military Park or Eisenhower National Historic Site in Gettysburg, Pennsylvania.

2.0 GENERAL

A. Trees to be taken down or pruned will be tagged by NPS personnel prior to contractor arrival.

B. Any additional tree or debris removal incidental to felling a tagged tree shall be included in cost of felling the tagged tree.

C. Logs and branches:

a) Chips will be removed unless otherwise directed by the COR.

b) Logs and branches will be removed by the contractor, with the exception of “Witness Tree” wood as identified by the COR.

D. Stumps:

a) Grind all stumps to a depth not to exceed 4” below grade. Stump grindings are to be left on site to preserve any potential archeological resources.

E. Trees that overhang Roads: Branches hanging over roads will be cut back to a height of no less than 13.5 feet above the ground.

F. Trees that overhang Sidewalks and Trails: Branches hanging over sidewalks and trails will be cut back to a height of no less than 10 feet above the ground.

G. All hung tree limbs must be placed on the ground as soon as possible but no later than by the end of each work day.

H. All roads and sidewalks must be left clear of cut stems and branches.

I. Climbing spikes shall not be worn.

J. Vehicles: No vehicles shall be permitted to travel over or park within the area generally defined by the canopy of a tree, except if the tree is to be removed and/or if a bucket truck is the only safe means to treat a tree. The root zone of neighboring trees which are not being treated shall not be traveled over. Load distribution matting may be used.

K. Access to certain areas with large equipment is at the discretion of the Contracting Officer’s (CO)

Representative (COR) or Technical Expert on site.

L. All workers to comply with Federal, State and Local safety requirements.

M. The contractor shall be responsible for ground rehab such as rutting and turf damage.

N. The Contractor shall not permit heavy equipment or vehicles or the stock piling of heavy materials off hard surface roads without the expressed permission of the COR. Limited activity may take place, within the root protection area, with the expressed permission of the COR, only 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). Any damage resulting from such operations shall be repaired to original condition or to the satisfaction of the COR, at no additional cost to the Government.

O. The Contractor will be held responsible for any damages to, and for maintenance and protection of existing structures and utilities.

P. The Contractor shall preserve and protect all existing vegetation such as trees, shrubs, and grass areas (on or adjacent to trees being removed) which do not reasonably interfere with work. The Contractor shall be responsible for all unauthorized cutting or damage to trees and shrubs, including damage due to careless operation of equipment, stockpiling of materials or tracking of grass and other surfaced areas by equipment. Such damaged areas or materials shall be restored, repaired or replaced by the Contractor at no additional cost to the Government.

Q. Pneumatic tires are a requirement and pavement protection for vehicles over 10,000gvw is required in sensitive areas (2’ rigid foam with two layers of ¾” plywood) Sensitive areas are defined by Historical value and environmental conditions, underground utilities, paths and walkways.

R. The Contractor will be required to furnish all labor, materials, and equipment for cleanup and restoration of all disturbed areas or features, which have been damaged during the course of this contract.

S. Trees identified as “Witness Trees” are not to be removed from the park except for a chipped debris. Any material larger than the capabilities of the chipper, the COR will identify a location for the contractor to deliver the remaining wood to.

T. Trees cannot be fallen onto protected resources like earthworks, stone walls, and other protected resources. Trees growing out of earthworks will be cut as flush to ground as possible. If necessary, some trees may require limb removal prior to felling to diminish the impact of the tree on the ground surface.

No heavy equipment will be authorized for use on top of any earthwork.

U. The Contractor shall provide, erect, and maintain all necessary barricades, danger signals, detour and other signs, and take all necessary precautions for the protection of the work and safety of the public. All such barricades and signs shall be in accordance with the Manual of Uniform Traffic Control Devices (MUTCD, 2003 Edition, as published by the Federal Highway Administration, U.S. Department of Transportation.

V. Preservation of Cultural Features: Confine all operations to work limits of the project. Prevent damage to cultural features. At Gettysburg National Military Park, the cultural landscape (i.e. the cemetery, fences, lanes, tree lines, building complexes, fields and other features that make up the battlefield) is nationally significant and must be protected. Each feature consists of elements that contribute to its significance.

For example, the width, alignment and materials of farm lanes contribute to their significance and must be protected. The elements that are considered significant to cultural features must be protected if possible and restored if disturbance is unavoidable.

1. Keep all disturbances to cultural features to a minimum. Use the narrowest possible construction corridor when a cultural feature, such as a fence or lane, must be crossed or otherwise disturbed. Restore all disturbed cultural features to their pre-construction condition, replacing fences, sections of lanes, and cultural landscape features in kind, at no additional expense to the Government. Coordinate with the Contracting Officer for disturbances to cultural features.

2. Provide temporary barriers to protect cultural features.

3. Do not fasten ropes, cables or guys to existing cultural features.
