APPENDIX A

TECHNICAL SPECIFICATIONS FOR SERVICE WORK ITEMS

SECTION I – DESCRIPTION OF WORK:

The Bighorn Retreat is part of the Harris park EA located on the South Platte Ranger District of the Pike National Forest, approximately 11 miles north of Bailey, Colorado. Land management objectives for the project area are summarized as follows:

• Increase Stand Resiliency— Promote a diversity of tree species, age classes, and structural stages that would lead to the development of uneven-aged stands.

• Reduce the negative impacts that wildfire could have on watersheds, including the municipal watershed reserves and water system infrastructure for the cities of Denver, Aurora, Bailey, and other local municipalities.

• Maintain and enhance threatened, endangered and sensitive species habitats, and other important wildlife habitats over the next 20 – 30 years – Promote the perpetuation of aspen for wildlife habitat.

Special Considerations for All Units:

Cutting Unit Boundaries

The boundaries of cutting units are designated as shown in the following table. The trees used for boundary designation are not to be cut.

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 the digital vector file/shapefile named BighornRetreat_Units.shp and dated December 2nd 2025 . The digital vector file/shapefile will be provided to the Purchaser by the Forest Service. A digital list of the coordinates can be provided upon request.

Included Timber is located within and not past the boundary as shown on the mobile mapping device using the digital vector file/shapefile listed above. Purchaser is responsible for obtaining a GPS receiver(s) that is capable of determining the location of the true Geo-Fence within the contract tolerance. Allowable contract tolerance is 20 feet.

Forest Service inspection of cutting Included Timber to determine if cutting is within allowable contract tolerance, shall use the digital vector file/shapefile named and dated above using a GPS Receiver with a minimum, tested accuracy in a light - medium canopy of 5 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.

As an operational convenience and subject to written agreement by the Forest Service, in advance of marking, Purchaser may mark Geo-Fence boundaries on the ground with Purchaser's non-tracer paint. Boundary trees shall not be identified with paint applied below stump height. Purchaser shall bear all costs associated with painting used to visually identify boundaries. Forest Service will not approve or accept the boundaries identified on the ground by the Purchaser in advance of cutting.

In case of a major disruption in GPS service, or lack of GPS coverage on the Sale Area beyond the control https://www.fs.usda.gov/database/gps/mtdcrept/accuracy/index.htm

Page 2 of 12 South Platte Ranger District of the Purchaser, as determined by the Contracting Officer, lack of GPS coverage on the Sale 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.

Purchaser may request Forest Service Marking of Geo-Fence boundaries on the ground with paint at Purchaser's expense. Approval by the Contracting Officer is subject to agreement and the availability of Forest Service personnel. If Purchaser's request is approved, Forest Service determination of boundary location will be final.

SECTION IV – INSPECTION AND ACCEPTANCE

For All Work Items:

At any point during the project, the Contractor and/or Project Manager may request (documented through email, text, or hand-written request) an in the field consultation with the Forest Service to inspect work progress, review contract specifications, or clarify issues. The Forest Service shall respond to Contractor’s request within 5 working days, excluding weekends and federal holidays.

GOVERNMENT QUALITY ASSURANCE SURVEILLANCE PLAN

Government Inspection Procedures - The COR, or a designated inspector (GTM), will make periodic inspections while work is in progress, usually daily at first, as needed to assure work is proceeding satisfactorily. The Contractor shall notify the COR when units are started, when problems are encountered and when contract work needs government oversight.

1. Each unit will be inspected as a separate unit. Unit will not be averaged with other units for acceptance or payment.

Page 6 of 12 South Platte Ranger District

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)

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:

Unit Acreage Minimum No. of Plots 1 – 9 1 plot per 2 acres 10 – 29 10 plots 30 – 59 1 plot per 4 acres 60 – 99 20 plots 100 1 plot per 5 acres

7. Determination of acceptability of the work performed will be based on Government verification inspections and will be considered conclusive.

8. At each plot, the Government will examine the plot area and record findings on the items listed below:

a. Plot number

b. Number of trees to be left on plot.

c. Number of trees left on plot.

d. Number of satisfactory trees.

e. Number of deficient trees.

f. Number of excess trees.

- Stumps containing live limbs which are not in accordance with specifications herein will be counted as excess trees.

- Cut trees which are still attached at the stump will be counted as excess trees

- Trees meeting cut specifications will be counted as excess trees

Page 7 of 12 South Platte Ranger District

- Trees in excess of trees to be left will be counted as excess

9. Work quality will be calculated on the form as follows:

No. Trees Deficient + No. Excess Trees -------------------------------------------------- = % Unsatisfactory work No. Trees to be left

100% – % Unsatisfactory work = % Work Quality

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 excess trees, 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.

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.

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 acre 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 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 1-3

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 95 percent or higher, 5 percent (adjustment for statistical variation) will be added and the Contractor will be paid 100 percent of their bid rate.

(b) For work quality from 85 to 94 percent, the 5 percent will be added to the work quality percent and the Contractor will be paid the total multiplied by the bid rate.

(c) For work quality 84 percent and less, the 5 percent will not be added and there will be no payment made to the Contractor.

(d) If, after rework, the percentage of satisfactory work is between 85% and 94%, payment will be made by the actual percentage. If the percentage is less than 85%, the work is unacceptable, and no payment will be made.
