This document is Appendix A: Technical Specifications for Service Work Items for the Banana Peel Designation by Prescription (DxP) Integrated Restoration and Stewardship Contract (IRSC) on the San Juan National Forest, Mancos-Dolores Ranger District. The contract encompasses forest management activities across 10 cutting units totaling approximately 668 acres, with objectives to increase forest resiliency, reduce bark beetle epidemic risk, promote age class diversity, reduce wildfire severity risk, and provide commercial and non-commercial wood products. The work includes mandatory items covering 225.4 acres: cutting and removing ponderosa pine live sawtimber (9.0" to 21.9" DBH) from Units 1, 2, 5, 6, and 10 (142.7 acres, 1,248 CCF); cutting, skidding, and decking non-sawtimber and dead sawtimber from Units 1, 2, and 6 (82.9 acres); and cutting, skidding, and piling non-sawtimber from Units 5 and 10 (59.8 acres).
Optional items include cutting and removing sawtimber from Units 3, 4, 7, 8, and 9 (391.8 acres, 3,425 CCF); cut, skid, and deck operations in Units 7 and 9 (140.5 acres); cut, skid, and pile operations in Units 3, 4, and 8 (251.3 acres); and road decommissioning and boulder placement across multiple road networks totaling 10,409 linear feet of road work and 135 boulders. All cutting units contain specifications for tree selection, stump heights (maximum 12"), processing standards, slash piling requirements, and skid/deck specifications. The government requires 90% minimum acceptable quality levels (AQL) for cutting and piling items, with 100% AQL for road decommissioning and boulder placement. Work is restricted during periods of high fire risk, excessive soil moisture, deep snow conditions, and when wildlife nests or cultural sites are discovered. Unit 2 is prioritized for initial treatment. Payment is based on acreage rounded to the nearest tenth of a decimal for cutting work, with rates adjusted based on work quality ranging from 0% payment for work below 79% quality to 100% of bid rate for 90% or higher quality work.

The Contractor shall notify the COR when units are started, when problems are encountered and when contract work needs government oversight.
Page 6 of 12 Mancos-Dolores Ranger District
1. Each unit will be inspected as a separate unit. Unit will not be averaged with other units for acceptance or payment.
2. When units are completed and ready for government inspection, Contractor’s designated Project manager shall request unit inspection in writing, prior to moving out of the general area.
3. The COR, or designated inspector, will determine compliance with contract specifications through informal visual inspections. In the event visual inspection indicates work to be in non-compliance with specifications, prompt corrective action and/or rework shall be required.
Government Inspection Procedures – Formal (Plots) - Items 1,2, 3, 4, 5 and 6
1. In the event visual inspection indicates work and / or rework to be in non-compliance with contract specifications, a series of verification plots shall be installed by the Government to determine compliance with specifications and percent of satisfactory work for treatment of each unit not meeting specification as observed with visual inspection.
2. Government verification plots will consist of a series of fixed area plots and variable radius plots along transects to record whether density, basal area, best tree selection, and other requirements are being met and to what extent.
3. Plots and grid will be distributed so that a representative sample is obtained.
4. The COR or designated inspector will mark the center of each plot on the ground using flagging, stakes, or pin flags. Additional flagging will be hung near the plot center so that it may be seen from a distance.
The inspector will include the plot number, their initials and date on the flagging.
5. Plots will be numbered to correlate with the inspection form and transects on a unit map.
6. The minimum number of verification plots, per treatment unit, shall be as follows:
Minimum No. of Plots 1 plot per 40 acres
At least 4 plots per Cutting Unit
7. Determination of acceptability of the work performed will be based on Government verification inspections and will be considered conclusive.
8. Plots will determine as pass/fail according to Appendix B, C6.36# - Acceptance of Work.
Unsatisfactory Cutting
1. If the work quality falls below 85 percent, the COR will immediately notify the Contractor, in writing, and order him to improve the quality of subsequent tree cutting. If the quality of subsequent tree cutting is not raised above the 85 percent minimum acceptable standard within 24 business hours after receipt of such written notice, the Contractor’s right to proceed may be terminated and the contract considered in default.
2. When the work quality falls below 90 percent as a result of C6.36# - Acceptance of Work criteria, the Government may elect to do one of the following:
a. Order rework to be performed and withhold payment until excess trees are cut and the results of a post-rework Government inspection show work quality to be at least 85 percent or more. No rework shall be performed unless ordered or authorized by the COR.
b. Order that no rework be performed and payment will either be made at a reduced rate, or not at all, as determined from the Thinning Inspection Report.
Page 7 of 12 Mancos-Dolores Ranger District
3. Repeated failure to produce work quality at or above the 85 percent minimum acceptable standard will be considered reason for contract termination and default action.
Government Inspection Procedures – Formal (Plots) - Items 7a, 7b, 8a, 8b, 9a, 9b, and 10
1. Visual inspections will be used to verify compliance with contract specifications.
a. Boulder Placement: Correct placement/delivery of boulders
b. Road Decommissioning: Roads are ripped and seeded to adequate depth and seeding rate.
2. Road work requires 100% AQ Levels.
Reinspection Upon Contractor Request
1. If Government inspection results are unacceptable to the Contractor, a reinspection may be requested, in writing, within 5 business days after receipt of notice of said inspection results. The same inspection procedure will be used; however, the inspection pattern will be shifted so that new inspection plots will not overlap previously inspected plots.
2. If reinspection results – rounded up to the nearest whole percent – indicate a variance of more than 5 percent from the first inspection, the results of the second inspection will be used to calculate work quality and payment, and the Government will bear the cost of reinspection.
3. If reinspection results – rounded up to the nearest whole percent – are within 5 percent of the first inspection, plots from the initial inspection and the reinspection will be combined and used to calculate work quality and payment, and the Contractor shall bear the cost of reinspection.

SECTION V – PAYMENT METHODS
Method of Measurement for Acreages
Acreages and miles were determined by using Global Positioning Systems (GPS) or digitized using GIS mapping.
Some unit boundaries are flagged, the majority of boundaries are virtual.
Discernable Boundaries are boundary locations that are readily identifiable features on the ground in locations shown on the Contract Area Map. A Geo-Fence is a location on the ground corresponding to the boundary location shown on a mobile mapping device using a Global Positioning System (GPS) Receiver using a digital vector file/shapefile. The digital vector file/shapefile will be provided as an attachment to the Contractor by the Forest Service. A digital list of the coordinates can be provided upon request.
Contractor is responsible for obtaining a GPS receiver(s) that is capable of determining the location of the geo-fence boundary within the contract tolerance. Allowable contract tolerance is 40 feet.
Forest Service inspection of treatment boundaries shall be conducted to determine treatments are within the allowable contract tolerance using the digital vector file/shapefile referenced above using a GPS Receiver with a minimum, tested accuracy in a Light- Medium canopy of 20 feet.
National Technology Development Program GPS Receiver accuracy reports by GPS manufacturer and model are available at: https://www.fs.usda.gov/database/gps/mtdcrept/accuracy/index.htm. Forest Service determination of boundary location will be final.
In case of a major disruption in GPS service, or lack of GPS coverage on the Contract Area beyond the control of the Contractor, as determined by the Contracting Officer, extension of time may be granted by Contracting Officer when requested in writing by Contractor in accordance with 52.212-4 (f) Excusable Delays. To resolve major disruption of GPS service, or lack of GPS coverage on the Contract Area, the Forest Service may elect to Mark Geo- Fence boundaries on the ground, in which case the Forest Service’s determination of boundary location will be final.
The acreage for each work item will be rounded to the nearest 10th decimal and miles will be rounded to the nearest hundredth of a mile. Acreage and milage is final unless:
a. The contract is modified or,
b. The Government makes a determination to remeasure or,
c. The Contractor exercises his/her option under the following Remeasurement provisions:
Remeasurement
1. The Contractor may request, in writing, remeasurement of any units under this contract if he/she feels that acreage or milage stated on the project maps is incorrect. The remeasurement must be within the existing perimeter of the respective unit or existing centerline of the road. No variance of the unit perimeters or road as identified on the maps for this contract will be allowed. All requests for remeasurement must be made prior to payment for each completed unit. Remeasurement will be performed by the Government.
2. If remeasurement indicates that a variance of ten percent or less exists on units of 1 to 5 acres, five percent or less exists on units of more than five but less than 20 acres, or if three percent or less exists
Page 9 of 12 Mancos-Dolores Ranger District on units of 20 acres or larger, the Contractor shall pay for the actual costs of the remeasurement. Under this condition, payment will be made on the acreage stated on the project maps. If the remeasurement indicates the actual acreage varies by more than the above factors from that stated on the project maps, the payment will be made on the remeasured acreage and the Forest Service will pay for the cost of the remeasurement.
Acceptance and Payment – Items 1, 2 , 3 , 4, 5, 6, Cutting and Removing Timber, Piling, Cut Skid and Decking
1. If informal visual inspection indicates acceptable work quality, the Contractor will be paid 100 percent of their bid rate.
2. In the event that formal inspections are used, the rate of payment to the Contractor will be calculated as follows:
(a) For work quality of 90 percent or higher, the Contractor will be paid 100 percent of their bid rate.
(b) For work quality from 80 to 89 percent, the Contractor will be paid the total multiplied by the bid rate.
(c) For work quality 79 percent and less, no payment made to the Contractor.
(d) If, after rework, the percentage of satisfactory work is between 80% and 89%, payment will be made by the actual percentage. If the percentage is less than 80%, the work is unacceptable, and no payment will be made.
Acceptance and Payment – Item 7a, 7b, 8a, 8b, 9a, 9b, 10 Road Decommissioning and Boulder Placement
1. Full payment will be made when visual and/or measurement inspection indicates specifications have been met and the roads are sufficiently closed and blocked to vehicle traffic
2. Only one rework opportunity will be allowed for this item.
SECTION VI – DEFINITIONS
ACCEPTABLE QUALITY LEVEL (AQL): Acceptance of work will be based on compliance with all specifications corresponding to the appropriate task(s). A minimum AQL is required for all service work – hand or mechanical. The minimum AQL will receive a satisfactory performance rating.
ADVANCED REGENERATION: Young, healthy, dwarf mistletoe-free conifers, less than 5.0 inches in diameter, free of defect.
ASPEN CLONE: A collection of vigorous aspen trees sharing the same root system.
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.
CLUMPS: Clumps are collections of two - eleven trees growing close in proximity. Trees within clumps directly affect each other’s growth and form, and their crowns are interlocked. The boles of trees within clumps either touch or grow very near to each other (within 8 ft.).
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.
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.
Page 10 of 12 Mancos-Dolores Ranger District
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 2 feet 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% 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. Any tree that has pitch tubes indicating Pine Beetle infestation.
DESIGNATION BY PERSCRIPTION (DXP): A cutting designation where a prescription is used to determine which trees will be left and which will be cut.
DIB: Diameter inside bark.
DRC: Diameter at root collar measured 6 inches above the ground level on the uphill side of the tree.
HANG-UP TREE: Any cut tree suspended above ground level.
INDIVIDUALS: Individual trees are open grown and receive full sunlight. They are not directly impacted by other trees. The post-harvest stand should contain individual trees of varying size/age classes.
INTERSPACE: The open area found in between clumps and individual trees. Interspace is smaller than openings. Patches of interspace are irregular in shape but are often 10-50 feet in size.
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 all conifer species, minimum diameter of 5 inches DBH to maximum diameter
8.9 inches DBH.
OPENINGS: Areas up to two acres in size (though they are usually smaller) that are free of trees (excepting advanced generation). Within treated stands, openings may be created when areas of dead, mistletoe-infected, or beetle-infested trees are cleared. Openings can also be created when regeneration is present.
The post-harvest stand should contain openings, but they should not actively be created other than by clearing around regeneration, removal of dead, mistletoe-infected, or beetle-infested trees.
PAYMENT UNIT: See Treatment Unit.
PILING: Gathering and stacking of downed wood and activity slash by hand or mechanical methods into piles constructed and located as indicated by technical specification and project maps.
PROGRESSION OF WORK: Work conducted in a progressive, workmanlike and orderly manner by the Contractor.
