GOVERNMENT QUALITY ASSURANCE SURVEILLANCE PLAN

Government Inspection Procedures

The COR, or a designated inspector, 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.

The Government will inspect completed units as a basis for acceptance and payments, and to provide recommendations to improve work quality while work is in progress. The government reserves the right to use any inspection method it deems appropriate to assure adequate Quality Control. The Contractor is responsible for providing quality control to assure that work complies with requirements of contract specifications.

All work included in the contract specifications shall be subject to inspections by the Government at periodic intervals during the performance of this contract. Treatment inspections are for the sole benefit of the Government and shall not release the Contractor of the responsibility of providing quality control measures to assure that the work strictly complies with the contract requirements.

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.

4. The method of inspecting the contractor’s required leave tree mark prior to harvest operations will be completed by visual inspection.

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

Printer Boy DxP Stewardship IRSC Page 9 of 17

Work quality

Work quality percentages are derived from data developed from inspection plots. The total number of satisfactory plots divided by the number of plots inspected determines the quality rate. This rate multiplied by 100 provides the work quality percentage.

Example: Number of plots inspected 25 Number of satisfactory plots 23 23 divided by 25 .92 Work Quality Percentage 92%

Acceptance of work will be based on compliance with all Appendix A, Section II Work Items and Appendix B, C2.355# Designation by Prescription that corresponds to the treatment. A minimum basic quality of 90 percent is required to meet the Acceptable Quality Level.

Unsatisfactory Work

If the work quality falls below 90 percent, the COR will immediately notify the Contractor in writing and direct the Contractor to improve the quality of work. If the quality of work is not raised to an acceptable level within 30 working days after written notification, the Contracting Officer may issue a Suspend Work Order to resolve the problem, during which time contract performance time will continue to run. All work that does not meet contract requirements shall be reworked at no cost to the government until it meets contract specifications. If the contractor does not make the necessary corrections, the Contracting Officer may reduce payment based on the percentage of unacceptable work. Disagreement between the parties will be subject to the clause entitled “Disputes”.

1. When the work quality falls below 90 percent, the Government may elect to do one of the following:

(a) Order rework to be performed and withhold payment until the results of a post-rework Government inspection show work quality to be at least 90 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 Inspection Report.

2. In the event that work is performed that is contrary to the requirements in the task order the Government is not liable for costs incurred by the contractor during negligent performance that is without the fault or negligence of the Government.

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.

Government Inspection Procedures – Mandatory Items 2, 3, and 4

1. For sawtimber and non-sawtimber trees, the method of inspecting purchaser cutting will be done using 20 BAF

b. The Government makes a determination to remeasure or,

c. The Contractor exercises his/her option under the following Remeasurement provisions:

Remeasurement

Printer Boy DxP Stewardship IRSC Page 11 of 17

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 – Mandatory Items 2, 3, and 4

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 80 percent of their bid rate.

(c) For work quality from 70 to 79 percent, the Contractor will be paid 70 percent of their bid rate.

(q) DMR (Dwarf Mistletoe Rating) – A standardized system called the Hawksworth 6-class mistletoe rating system (DMR) used to determine how much dwarf mistletoe has infected a tree. To use this system, the living part of the tree crown needs to be broken up into 3 sections, (top, middle, bottom). Each section is then rated either 0, 1, or 2 with a score of 0 being assigned for an uninfected section, 1 for light infection with less than half of the branches infected, or 2 for heavy infection with over half of the branches infected. The 3 numbers are then added together to give the total rating for the tree.

(r) Erosion control – Activities designed to prevent/reduce the delivery of sediment to area streams as a result of road building and/or timber harvest. Activities typically include grass seeding and/or installation of structures to trap moving sediment.

(s) Hand Pile- A method of piling slash with the use of manual labor. Piling may also be done by other methods.

(t) Hand Treatment – A method of treatment completed using manual labor and equipment such as power saws.

(u) Leave Tree – Any tree that is selected or required to be left standing as provided in the specifications.

(v) Leave Tree Marking – A method of timber designation whereby all conifer trees >5.0” DBH that are not marked with Orange paint above and below stump height are designated for cutting.

(w) Limb and Top Removal – The moving, during yarding/skidding, of cut tree and tops to a designated location at the landing.

(x) Machine Pile – A method of piling slash with the use of mechanized equipment. Piling may also be done by other methods.

(y) Manual Treatment – A method of treatment completed using manual labor and equipment such as power saws.

(z) Mechanical Treatment – A method of treatment using machinery such as feller bunchers, harvesters, processors etc.

(aa) NFSR: National Forest Service Road.

(bb) Non-sawtimber – Included timber meeting non-sawlog size specifications as defined in Appendix B. or Trees that are > 5.0” DBH to < 6.9” DBH for lodgepole pine, excluding aspen.

(cc) Piling: Material moved to an agreed upon location shall be piled for future treatment by Forest Service.

(dd) Plot: A sample plot within a cutting unit that is used to determine the number of desirable trees and other contract specifications.

(ee) Slash - Debris created from work under this contract including all cut trees and their tops, trunks, and limbs.

(ff) Sawtimber – Included timber meeting the Utilization Specifications as defined in Appendix B, Division A.

(gg) Streamcourse - The area along a stream that has riparian vegetation and other riparian characteristics.

Streamcourses are noted on the project maps. They typically require special treatment which may include alteration to the tree cutting, slash treatment, vehicle travel, or fueling of saws.

(hh) Stump Height – A point on the bole of the tree from the uphill side that is 12” above the ground for Sawlog trees and 6” above the ground for non-saw and biomass trees.

(ii) Thinning – The cutting of trees in excess of those to be left for future management

(jj) Tree Crown – The total of an individual tree's aboveground parts, including stems, leaves, and reproductive structures.

(kk) Unsatisfactory Work: If work quality falls below the AQL, the COR will issue a work order or notice of noncompliance to the Contractor in writing. Untreated or unsatisfactory treated areas shall be reworked to obtain satisfactory work quality.
