APPENDIX A

TECHNICAL SPECIFICATIONS FOR SERVICE WORK ITEMS

SECTION I – DESCRIPTION OF WORK:

The objectives of this project are to perform mitigation treatment of standing and downed fire killed fuels along and adjacent to roads within the North Complex Fire of 2020. These roadside fuels treatments are a vital step of the continued post-fire restoration activities to ensure safe access and working conditions. The project will also reduce the risk of future wildfire and insect or disease infestation in the Tamarack Flat area and protect, restore, and enhance forest ecosystem components within the project area.

1. Mechanically remove unmerchantable trees and small diameter hazardous fuels along roadsides to landings to be later burned by FS or chipped/removed from contract area. Deck merchantable logs for possible removal.

2. Cut and pile hazardous fuels within meadow units if awarded.

3. Remove product per Timber Subject to Agreement if awarded.

The Forest Service shall respond to Contractor’s request within 5 working days, excluding weekends and federal holidays.

GOVERNMENT QUALITY ASSURANCE SURVEILLANCE PLAN

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 – Items 1, 2, and 3

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 that will have 4 quadrants of pass or fail.

3. Plots and grid will be distributed so that a representative sample is obtained. Pile locations including landings may be sampled in plots to determine overall quality.

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

Plumas NF, Feather River RD Page 8 of 12

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 satisfactory trees.

c. Number of excess trees.

d. Number of unacceptable and/or acceptable piles.

Cut trees which are still attached at the stump or not severed below the lowest live limb, except when prevented by obstacles (e.g. rocks, boulders) 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 Live limbs below the cutting point not removed at the bole will be counted as excess Trees and brush felled into leave-trees, unit boundaries, streams, roads, established trails

(recreation, game, stock, etc.) cultural resource sites, and other improvements (e.g. fences, established land corners, buildings, ditches, etc.) will be unacceptable.

Government Inspection Procedures – Item 4

The COR, or a designated inspector (GTM), will make periodic inspections of loads in transit per standard utilization inspection procedures, log storage and transfer locations prior to re-loading and transporting via rail if applicable. Government reserves the right to inspect product end-delivery locations to ensure domestic processing of products transported via rail. Scale certifications of surplus products will be compared to rail transport invoiced quantities.

Table 1 – Minimum Acceptable Quality Levels (AQL) of Work

ITEM DESCRIPTION SCHEDULE UNIT MIN

AQL

1 Hazard tree-cut and pile roadside trees MANDATORY Acre 90%

2 Mechanical cut and pile dead trees in meadows OPTIONAL Acre 90%

3 Manual handcut and pile dead trees in meadows OPTIONAL Acre 90% 4 Removal of Timber Subject to Agreement OPTIONAL TON 100%

Unsatisfactory Performance

1. If the work quality falls below the minimum AQL, the COR will immediately notify the Contractor, in writing, and order him to improve the quality of subsequent tree cutting.

2. If after rework has been performed and reinspected, and work quality still falls below minimum AQL percent, payment will either be made at a reduced rate, or not at all, as determined in SECTION V below.

Plumas NF, Feather River RD Page 9 of 12

3. Repeated failure to produce work quality at or above the minimum acceptable standard will be considered reason for contract termination for cause.

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). 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 Re-measurement provisions:

Re-measurement

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 re-measurement 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 re-measurement. Under this condition, payment will be made on the acreage stated on the project maps. If the re-measurement 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 re-measured acreage and the Forest Service will pay for the cost of the re-measurement.

Acceptance and Payment –Items 1, 2, and 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

Plumas NF, Feather River RD Page 10 of 12 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 85 to 89 percent after rework, the Contractor will be paid the total multiplied by the bid rate.

(c) For work quality 84 percent and less after rework, no payment made to the Contractor.

Acceptance and Payment – Optional Item 4

Full payment shall be made for the actual quantity of product removed upon receipt of acceptable proof of removal/transport for quantities invoiced. The number of tons awarded represents the ceiling amount for which a contractor could be paid without modification but is not a guarantee. Funds not utilized to pay for removal shall be de-obligated at the end of the contract or utilized for other supplemental agreement(s) if it is in the best interest of the government.
