TECHNICAL SPECIFICATIONS FOR SERVICE WORK ITEMS

SECTION I – DEFINITIONS

1.1 DEFINITIONS

ACCEPTABLE QUALITY LEVEL: Acceptance of work will be based on compliance with all specifications corresponding to the appropriate task(s); refer to the Performance Requirements Summary in Section E.4 of Contract.

A minimum AQL is required for all service work – hand or mechanical. The minimum AQL will receive a satisfactory performance rating.

BIOMASS TREES: Any conifer material 2.0 foot in height to 4.9 inches DBH.

BOLE SPACING: The horizontal distance in feet from the edge of one leave tree bole to another leave tree bole, measured from the outside bark of each tree.

CIRCULAR PLOT: A sample plot within a thinning unit that is used to determine the number of desirable trees and other contract specifications.

COARSE WOODY DEBRIS: Woody material left on the ground to meet wildlife habitat requirements.

CROWN RATIO: The ratio of live crown length (tip of leader to base of the crown) to total tree length/height.

CROWN SPACING: The horizontal distance in feet between the dripline of a live crown to another live crown.

CUT TREES: Trees that do not possess the characteristics of desirable leave trees, and are required to be cut. As described by the contract or otherwise marked to be cut.

CUTTING UNIT: see Treatment Unit definition

DAMAGED TREES: Trees damaged beyond recovery. A tree that is larger than 18 inches in height, and has the top knocked out, is leaning more than 10 degrees, has less than one half of its original limbs, or has approximately 50 percent of bark removed from the circumference of the bole.

DBH: Diameter at breast height, measured at a point of 4.5 feet above the ground level on the uphill side of the tree.

DECKING: Stockpiling of trees in a designated area.

DEAD/DYING TREES: Trees with the crown foliage changing from green to red, yellow, or needleless.

DIB: Diameter inside bark.

HANG-UP TREE: Any cut tree suspended above ground level.

LEAVE TREE: Trees that possess desirable characteristics and that serve to create the basis for designated spacing requirements, or are otherwise designated to be left.

NON-SAWTIMBER TREE: For Lodgepole Pine: 5.0 inches DBH – 6.9 inches DBH, and for Engelmann Spruce and Subalpine Fir: 5.0 inches – 7.9 inches DBH.

PAYMENT UNIT: See Treatment Unit.

PERFORMANCE REQUIREMENTS SUMMARY (PRS): Identifies the key service outputs of the contract that will be evaluated by the Government to assure contract performance standards are met by the Contractor.

PILING: Material moved to an agreed upon location shall be piled for future treatment by Forest Service.

PROGRESSION OF WORK: Work conducted in a progressive, workmanlike and orderly manner by the Contractor.

Elkhorn 3 IRSC Page 2 of 3

RESERVE CLUMPS: Groups of trees within a treatment area that are protected from cutting, may also include Individual Reserve trees.

SAWTIMBER TREE: Included timber meeting the Utilization Specifications as defined in Appendix B, Division A.2.

SKIDDING: The process of conveying felled trees or logs to a landing or designated location.

SLASH: Woody material existing or created that has accumulated on the forest floor. Woody material includes logs, pieces of logs, tops and branches.

SUBDIVISION: See Treatment Unit.

TEMPORARY ROADS: Non-permanent roads that are constructed by contractor for the purpose of Treatment Unit access.

TREATMENT UNIT: An individual area on the ground in which activities will be performed and which may appear as a separate pay item in the Schedule of Items.

UNSATISFACTORY WORK: If work quality falls below the AQL, the COR will issue a work order or notice of noncompliance to the Contractor in writing. Untreated or unsatisfactory treated areas shall be reworked to obtain satisfactory work quality.

WHOLE TREE LOGGING: Whole tree logging includes cutting tree and removing the entire tree, including tops and branches, to the landing.

WILDLIFE TREE: Standing tree marked to be reserved as a wildlife tree. Used by birds and small mammals for shelter, nesting, perching, etc.
