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.
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 at least one plot per two acres. Each cutting unit will have a minimum of two plots.
7. Determination of acceptability of the work performed will be based on Government verification inspections and will be considered conclusive.
Page 10 of 21 Leadville Ranger District
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.

SECTION VI – DEFINITIONS
ACCEPTABLE QUALITY LEVEL (AQL): Acceptance of work will be based on compliance with all specifications corresponding to the appropriate task(s); refer to the Performance Requirements Summary in Section E.4 of the contract. A minimum AQL is required for all service work – hand or mechanical. The minimum AQL will receive a satisfactory performance rating.
ACCEPTABLE SERVICE: A job performed to the standard and within the AQL. The Contractor must do the specific job, and meet the standard, and meet the AQL before one can say that performance has been acceptable and that the Contractor should be paid.
ASPEN STAND (AREA): Aspen areas are defined as an area where aspen reaches a diameter of 8.0 inches or greater DBH and there are 30 or more stems on 0.25 acre.
BASAL AREA : The area, per acre, that is occupied by the cross-section of tree trunks and stems at DBH, expressed in square feet per acre.
BIOMASS TREES: Any conifer material > 1 feet in height to < 4.9 inches DBH.
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.
CIRCULAR PLOT: A sample plot within a thinning unit that is used to determine the number of desirable trees and other contract specifications.
CLEARCUT: A cutting prescription in which all trees within a boundary are designated to be cut.
CLEARCUT W/RESERVES: A cutting prescription in which the cutting of all trees except for a small number of trees retained for seed production and to produce a new age class in fully exposed microenvironment or to attain goals other than regeneration.
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.
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.
CUT TREE MARKING: A method of timber designation whereby all trees marked above and below stump height with blue paint are designated for cutting.
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.
DECKING: Stockpiling of trees in a designated area.
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 PRESCRIPTION: A method of timber designation whereby a description of the outcome of timber cutting is used to prescribe the outcome of stand treatments. A sample area may be marked for demonstration.
DIB: Diameter inside bark. Diameter measurement of a standing tree or log in which the estimated or actual thickness of the bark is discounted.
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.
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.
HAND PILE: A method of piling slash with the use of manual labor. Piling may also be done by other methods.
