PART 5

SPECIFIC TASKS

5. Specific Tasks:

5.1. Basic Services: The contractor shall provide services for completion of the following maintenance specifications;

5.2. Boundary Maintenance Specifications:

a. The Contractor shall clear the boundary line to a width of four (4) feet on the government side of the fee line and to a height of seven (7) feet above the ground, except that no trees greater than two

(2) inches in diameter (measured at breast height) are to be cut unless authorized by the Government Representative. Where fences exist and are located on the property line, the contractor shall clear the government side of the fence in accordance with the specifications herein. All brush from the clearing shall be disposed of on Government property outside the cleared area. Vegetation cleared will be cut to within 6" of ground level. No grass will require cutting. Woody brush, vines, high weeds, river cane and briars will be cut when such items are in the above specified clearing zone.

b. Where trees are available adjacent to the boundary on Government property, they will be marked at intervals not to exceed 50' between markings along the fee line. Trees to be marked shall be not further than four (4) feet from the fee line. In addition to these trees, any trees which are a) over two (2) inches (measured at breast height), b) located on the government side within four (4) feet of the line, and c) within ten (10) feet either side of a monument, shall be painted. Markings will be a 4" wide, horizontal, white, painted ring at chest height (approximately 4.5' from the ground).

Paint is to be applied evenly by brush producing a solid coating of paint sufficient to cover the tree bark. A vertical white stripe, 12" long and 4" wide, will be painted across the horizontal stripe on the side of the tree adjacent to the boundary line. Line trees shall consist of a 4-inch vertical blaze bisecting a 4-inch band encircling the tree. The bands will be uniform and continuous, with no gaps present. Rough bark will be smoothed on all trees to be painted. Special care will be exercised to assure that bark is not removed into the cambium or living layer, which lies below the bark. On some species of trees with smooth bark, no material need be removed. In instances where no trees and only a fence row exists on the government side of the boundary line then posts should be painted every 50'. Only the top 8" of the post should be painted.

c. Contractor will furnish all paint. The quality of the paint shall equal or exceed Nelson’s Boundary Marking Paint (white, brushing type). Use of any other paint must be approved by the Government representative. As noted before, trees (where present) will be painted no less than 50' intervals and all posts will be painted. Existing posts will be prepped to provide a clean, smooth surface for the paint. This may require scraping, brushing with a wire brush, and/or wiping to remove rust, flaked paint, or algae. Posts must be dry prior to painting. It is estimated that two (2) gallons of white paint will be needed per mile of boundary.

d. Monument locations are marked with white painted steel T-post set near the monument. Care will be taken not to hit or disturb the monument or allow paint on the monument cap. Work in the field must proceed from monument to monument. Skipping an area is not allowed unless approved by the Government representative.

e. The Contractor will record in a hardbound journal all monuments located within the scope of this contract. The journal will list the monuments in sequence, noting if each monument was located.

One member of the crew will be responsible for keeping this journal of field notes updated daily.

This journal will also list the specific location, in relation to a boundary monument, including sketches, of any suspected encroachments on Government property. Copies of the journal will be given to the Government Representative upon the completion of each 5-mile stretch of boundary.

The journal will be given to the Government Representative at the end of the contract work.

f. Missing witness posts will be replaced by the Contractor. Five-foot tall T-posts shall be reset a minimum depth of 12", unless otherwise approved by the Government Representative. Posts replaced will be set on the Government side of the fee line 6" from the monument. The “cleats” on the post will point in the direction of the monument. All existing and replacement posts will be painted white. If two posts exist at a monument and one or both posts are damaged, then all damaged posts will be replaced. Damaged witness posts that are replaced shall be removed from Government property.

g. The use of a metal detector, GPS, hand-held compass, measuring tape or survey chain will be necessary to located hard to find monuments. Digging and using a metal detector will routinely be necessary to locate monuments that may be covered with leaves or soil, especially when the post is missing. If a specific monument is missing, the location will be marked in the field with a wire flag and the number of the missing monument will be written in permanent ink on the flag. The Contractor will furnish white wire flags. When monuments are missing, the course lines intersecting the missing monument shall not be cleared or painted. The present condition of the boundary line may be poor in many locations and show little evidence of past clearing, painting, or the existence of witness posts.

h. Boundary monuments will not be reset, or in any other manner disturbed.

i. The Contractor shall contact the government representative no less than weekly to report on work progress.
