APPENDIX A

TECHNICAL SPECIFICATIONS FOR SERVICE WORK ITEMS

SECTION I – DESCRIPTION OF WORK

The objectives of the Lincoln Springs Stewardship IRSC are to reduce hazardous fuels, increase the resiliency to wildfire and disease and improve forest health within the project area by using a variety of commercial, non-commercial, and prescribed fire treatments in the Lincoln Springs area of the Upper Blackfoot River Watershed.

The Lincoln Springs IRSC will address this with commercial and non-commercial timber activities. Forest products will be a combination of commercial sawtimber, non-saw and timber subject to agreement (TSTA). Proposed services will include road maintenance, yarding, processing, decking and landing piling, machine piling, mechanical thinning, thinning for hazardous fuels reduction, hand thinning and lopping and scattering.

SECTION II – WORK ITEMS

Applicable to Work Items 1, 3, 4, 5, 6a, 6b, 7and 8

Work item 1, boundary designations are described in Attachment B - C2.30# and displayed on Contract Area Map sheet 1 of 2. Work items 3, 4, 5, 6, 7, and 8 boundaries are identified on contract area maps and utilize requirements for virtual boundaries and pink flagging on the ground except where the boundary is painted adjacent to private property or alongside Special Measurement Areas.

Applicable to Work Items 3, 4, and 5

1. Mechanical operations, including piling will be conducted when soils are dry or during winter conditions.

Dry conditions must exist on greater than 85% of the unit, including landings. Winter conditions are 6” or greater of frozen ground, 10” or packed snow-covered soil, or a combination of both frozen and snow-covered ground if determined to be adequate.

2. Skidding equipment is limited to slopes less than 35%.

3. Designated skid trails will be placed at an average of 100’ apart, except where converging, with consideration for placement given to conditions within the units (such as existing disturbance, slope, rock cover). Mechanical operations will be excluded from wetlands and meadows to limit soil damage resulting from compaction, rutting, and runoff concentration leading to erosion as well as to minimize the potential for further spread of noxious weeds.

4. Landings and skid trails will be ripped/scarified where compaction after yarding and piling activities are complete. Any erosion control and drainage measures will be applied as appropriate immediately following completion of activities.

5. Equipment used for piling shall be approved by the Forest Service. Piles shall be reasonably compact and free of soil to facilitate burning.

Applicable to Work Items 7 and 8

1. Leave all quaking aspen or whitebark pine (5-needle pine).

2. Leave tree species preference: western larch > ponderosa pine > Douglas-fir > lodgepole pine > Engelmann spruce. Cut all subalpine fir.

3. Within spacing limitations and species preference, select the largest tree with a single, straight stem;

>40% crown ratio; no broken or dead tops; and no forks, crooks, sweeps, or leans greater than 15%.

Retain trees with no or little insect and disease issues. Cut Douglas-fir with evidence of western spruce budworm defoliation. If necessary to meet spacing requirements, retain Douglas-fir with the most live

Page 2 of 14 Lincoln Ranger District crown. Cut trees with stem cankers, mountain pine beetle pitch tubes, and dwarf mistletoe. Lodgepole pine with branch cankers and galls may be retained if it is the only available tree.

4. Leave trees will be spaced 15-feet away from the canopy drip line of mature (>8” dbh) trees.

5. Minimum tree height to cut is 12-inches tall.

6. Maximum tree diameter to cut is 6-inches diameter at breast height.

7. Maximum stump height is 6 inches above the forest floor with no live limbs left on the stump.

8. Refer to Section 41 – STREAMCOURSE PROTECTION and Contract Map 2 of 2 for detailed operational requirements and locations of Riparian Management Zones (RMZ).

9. Limbs will be lopped from tree stems and scattered. Slash depth will be 18 inches or less above the forest floor.

10. Tree stems will be bucked into 4- to 8-foot lengths so that slash is on or near the forest floor.

11. Drainages, trails, roads, and cut-slopes along the roadway shall remain free of slash at all times to prevent traffic flow issues or water runoff problems in ditches.

Mandatory Item 1: Cut and Remove Included Timber:

SECTION III – 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 for Thinning

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 1/20th acre (26.33’ radius) fixed area plots or variable radius plots along transects to record whether density (trees per acre), basal area, best tree selection, and other requirements are being met and to what extent.

3. Plots 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 5. Plots will occur on up to 1% of unit acres (each plot represents 0.05 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 using the Thinning Inspection Plot Form:

a. Plot number

b. Number of trees to be left on plot.

Page 8 of 14 Lincoln Ranger District

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

Government Inspection Procedures – Piling

1. In the event visual inspection indicates work and/or rework to be in non-compliance with contract specifications, all piles will be counted, piles that do not meet specifications 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.

Work quality will be calculated on the form as follows:

No. of Unsatisfactory piles -------------------------------------------------- = % Unsatisfactory work No. of total piles

100% – % Unsatisfactory work = % Work Quality

This will be calculated on a unit basis.

Unsatisfactory Cutting

1. If the work quality falls below 90 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 90 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

Page 9 of 14 Lincoln Ranger District 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 IV – PAYMENT METHODS

Method of Measurement for Acreages and Miles

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 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 34 feet.

Page 10 of 14 Lincoln Ranger District

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 15 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 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 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 – Item – 2 Road Maintenance

Visual Inspection: Acceptance is based on visual inspection of the work for compliance with the contract. Use prevailing industry standards in the absence of specific contract requirements or tolerances.

1. Partial acceptance. When a segment of the project is completed, a final inspection of that segment may be requested by the Contractor. If the segment is complete and in compliance with the contract, it may be accepted. If accepted, the CO may relieve the Contractor of further responsibility for maintenance of the completed segment. When public traffic is accommodated through construction and starts using sections of roadway as they are completed, continue maintenance of such sections until final acceptance.

2. Final acceptance. Notify the CO when the entire project is complete to schedule an inspection. If work is determined to be complete, the inspection will constitute the final inspection. The Contractor will be notified in writing of final acceptance as of the date of the final inspection. Final acceptance relieves the Contractor of further responsibility for the maintenance of the project.

If the inspection discloses unsatisfactory work, the CO will provide to the Contractor a list of the work that is incomplete or requires correction. Immediately complete or correct the work. Submit notification when the work has been completed.

Acceptance and Payment – Items 3, 4, 5, 6, 7 and 8: Thinning

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, 10 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 89 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.

3. Percentages as calculated herein shall be rounded to the nearest whole percent.

4. No allowance for variation or portion of a variation will be added which will create a percentage greater than 100 percent.

5. The payment rate for work quality at or above 85% will be calculated as follows:

% Work Quality + 5 % Statistical Variation (SV) = % Payment rate

6. 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

Page 12 of 14 Lincoln Ranger District

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

SECTION V – 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.

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.

BROWNS TRANSECT: A line intercept method for measuring the amount of fuel on the ground.

BRUSH: Vegetation consisting of shrub species with single or multi-stems originating at or near ground level not normally reaching more than 15 feet in height.

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.

CLEARCUT: A cutting prescription in which all trees within a boundary are designated to be cut.

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 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.

DEAD/DYING TREES: Trees with the crown foliage changing from green to red, yellow, or needleless. Any tree that has pitch tubes indicating Mountain Pine Beetle infestation.

DESIGNATION BY SPECIES AND DIAMETER (DXSD): A cutting prescription in which species and diameter are used to determine which trees will be left and which will be cut.

DIB: Diameter inside bark.

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

HEALTHY REGENERATION: Young, healthy, dwarf mistletoe free conifers, less than 4.9 inches in diameter, free of defect or characteristics.

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.

LOPPING AND/OR SCATTERING: Cutting limbs from trunks of cut trees, bucking, and moving and rearranging of slash concentrations to reduce the fuel bed height as specified.

NON-SAWTIMBER TREE: For all conifer species, minimum diameter of 5 inches DBH to minimum diameter by species identified in Appendix B, Division A.

OVERSTORY REMOVAL: A cutting prescription where all trees greater than a specified size are cut. Trees less than the specified size are protected.

PAYMENT UNIT: See Treatment Unit.

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

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 sawlog size specifications as defined in Appendix B, Division A.2.

STEEP SLOPE LOGGING: Cutting units with majority of slope greater than 40% adverse that may need specialized equipment to remove timber. This could be, but not limited to, tethered machines and or full suspension of timber.

SMALL ROUNDWOOD: Green needled ponderosa pine with a DBH of 4”-4.9” and minimum of 20’ in height.

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

UNIT: See Treatment Unit.
