Summary: Technical Specifications for Service Work Items - Moose Run Stewardship IRSC
This document is Appendix A to a Statement of Work (SOW) for the Moose Run Stewardship Integrated Restoration and Stewardship Contract (IRSC) on the Arapaho and Roosevelt National Forests, Sulphur Ranger District. The project aims to reduce crown fire potential, mitigate firefighter risk, reduce vertical fuel continuity, and improve stand health while maintaining species and structural diversity through two mandatory service work items across 96 total acres.
Mandatory Item 1: Cut and Remove Included Timber (Units 1, 2A, 2B, and 3 – 53 Acres) requires contractors to cut and remove all sawtimber and non-sawtimber products meeting minimum tree specifications, plus all dead Engelmann Spruce meeting specifications, with work subject to Appendix C requirements. Mandatory Item 2: Mastication (Units 4 and 5 – 43 Acres) requires mastication of live Lodgepole Pine at 4.9" DBH and smaller to 16 ft x 16 ft spacing, standing dead trees greater than 0.5" DBH, and down dead trees up to 6.0" diameter, with resulting slash not exceeding 3 inches diameter and 4 feet length, stumps capped at 12 inches above ground, and masticated material depth averaging 3-4 inches with 6-inch maximum. Work is restricted during periods of increased fire risk, when new nests are discovered, when soil moisture exceeds plastic limits, when snow depth prevents compliance, and when cultural or archaeological sites are discovered. Acceptance standards establish minimum Acceptable Quality Levels (AQL) of 98% for Item 1 and 90% for Item 2, measured through informal visual inspections and formal plot-based verification inspections. Payment calculation incorporates a 5% statistical variation adjustment, with work quality below 85% resulting in no payment. Unit boundaries are geo-fence locations provided via shapefile, with 30-foot contract tolerance and GPS receiver accuracy requirements of 20 feet minimum in light-medium canopy conditions.

Page 2 of 8 Sulphur Ranger District
Work may be done any time during the term of the contract, except under the following conditions:
(1) When conditions are such that operations shall be restricted or ceased due to increased fire risk.
(2) If new nests are discovered,
(3) When soil moisture exceeds the plastic limit as determined by the Forest Service.
(4) When snow depth creates a situation where requirements cannot be met and/or work cannot be inspected, as determined by the COR.
(5) If any cultural or archeological sites are discovered during operations of this contract, work will be suspended in the immediate vicinity of the site until a reconnaissance survey is completed by the Forest Archeologist. Areas excluded from treatment shall be deleted from the contract.
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.
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.
Page 3 of 8 Sulphur Ranger District
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
- 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:
Page 4 of 8 Sulphur Ranger District
(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 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 at award. 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 30 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.
Page 5 of 8 Sulphur Ranger District
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 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 stated on the project maps is incorrect. The remeasurement must be within the existing perimeter of the respective unit. No variance of the unit perimeters as laid out on the ground 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 – Item 1
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 98 percent or higher, the Contractor will be paid 100 percent of their bid rate.
(b) For work quality from 85 to 97 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.
Acceptance and Payment – Item 2 Mastication
1. If informal visual inspection indicates acceptable work quality, the Contractor will be paid 100 percent of their bid rate.
https://www.fs.usda.gov/database/gps/mtdcrept/accuracy/index.htm
Page 6 of 8 Sulphur Ranger District
2. In the event that formal inspections are used, the rate of payment to the Contractor will be calculated as follows:
(e) 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.
(f) 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.
(g) For work quality 84 percent and less, the 5 percent will not be added and there will be no payment made to the Contractor.
(h) 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.
Acceptance and Payment
1. Percentages as calculated herein shall be rounded to the nearest whole percent.
2. No allowance for variation or portion of a variation will be added which will create a percentage greater than 100 percent.
3. Payment rate for work quality at or above 85% will be calculated as follows:
% Work Quality + 5 % Statistical Variation (SV) = % Payment rate
4. Examples:
(a) 2 Trees Deficient + 4 Trees Excess 6 ------------------------------------------- = --------- = 5.22% = 5% Unsatisfactory work 115 Trees to be left 115
100% – 5% = 95% Work Quality 95% + 5% (SV) = 100% Payment rate
(b) 2 Trees Deficient + 9 Trees Excess 11 ------------------------------------------- = --------- = 11.96% = 12% Unsatisfactory work 92 Trees to be left 92
100% – 12% = 88% Work Quality 88% + 5% (SV) = 93% Payment rate
2 Trees Deficient + 14 Trees Excess 16 -------------------------------------------- = --------- = 16.84% = 17% Unsatisfactory work 95 Trees to be left 95
100% – 17% = 83% Work Quality - - No payment made
* Stewardship Credits will be earned first, whenever practical. Forest Service Funds will be used if the availability of Stewardship Credits is exhausted or if appropriated dollars are obligated to a specific item.
