C-7 Performance Standards

C-7.1. TASK: Selection of Leave Trees

(1) Species – The preference for leave trees species is the following order, unless specified differently on the Unit Data Sheet:

ponderosa pine western larch

Douglas-fir lodgepole pine grand fir

Spacing – The Unit Data Sheet(s) issued with each task order will specify the desired spacing between leave trees. To reduce the incidence of insect and disease problems in thinning units, the spacing guidelines may not be met. The average spacing will be varied plus or minus 25 percent to ensure retention of the best trees.

(b) Leave Tree Selection – The Contractor shall select leave trees based on the species preference specified on the Unit Data Sheet(s) and then the criteria listed below. The contract definition and specifications also help in determining leave tree selection. The Government may mark individual leave trees and/or groups of leave trees prior to thinning. The general concepts of leave tree selection are as follows:

(a) First, leave the most dominant trees, with at least 30 percent live crown, good color and form, free of insects and disease, and free of damage or defect.

(b) Second, leave co-dominant trees, with at least 30 percent live crown, good color and form, free of insects and disease, and free of damage or defect.

(4) Thinning in Riparian Habitat Conservation Areas (RHCAS), along streams, near springs, seeps, ponds, and reservoirs – The thinning prescription is usually modified when cutting trees near these bodies of water and dry streambeds. Generally a leave area is specified for a specific distance along both sides of a stream where no thinning is done. In other cases, the desired spacing between leave trees near creeks may be closer than the spacing specified for areas outside of the RHCA. The slash treatment may also be modified, with little or no bucking, loping or scattering specified. The Unit Data Sheet(s) issued with each task order will specify the treatment (or no treatment) within these areas. Unit maps will also detail the location of these features.

(5) Thinning in Botany Concern Areas – The thinning prescription is usually modified when cutting trees near and within botany concern areas. The prescription will be site specific for each unit. Some examples are, the prescription may allow thinning to occur up to the stream channel and other cases there may be directional falling requirements.

(6) Thinning around aspen or cottonwood – The thinning prescription is modified when cutting near aspen or cottonwood. Units containing these species will be identified on the Unit Data Sheets. More conifers shall be cut within a specified distance from aspen or cotton wood as detailed on Unit Data Sheet(s).

C-7.2. TASK: Cutting Methods

(1) Trees shall be cut below the lowest live limb. Stump height of cut trees shall be no higher than 8 inches above ground level.

(2) Trees shall be completely severed from the stump.

(3) No cut tree shall be left suspended in or leaning against a leave tree or tree outside the unit boundary.

(4) Girdling may be permitted as specified by Unit Data Sheets. No girdling will occur within 75 feet of any road, trail or dispersed campsite.

C-7.3. TASK: Slash Treatment

No thinning slash shall be allowed outside the contract boundary, unless otherwise approved by the Contracting Officer.

Contractor shall remove and scatter (pullback) all thinning slash from roads, fences and trails to keep them usable and passable at all times.

(A) Roads – within 10 feet of the cut and fill slopes on any road.

(B) Fences – within 10 feet each side of fences.

(C) Trails – within 10 feet each side of trails pathway.

(D) Firelines – within 5 feet from each side of fire line.

(E) Campground improvements – as specified on each task order

(3) Lop and Scatter – All slash shall be lopped and scattered except areas requiring handpiling (unless otherwise specified in the Unit Data Sheets).

(4) Bucking - All thinning slash shall be bucked to lengths not to exceed 10 feet.

C-7.4. TASK: Handpiling

Areas requiring handpiling are listed on the Unit Data Sheet(s) issued with each task order.

(A) Thinning slash to be piled includes material from ½ inch diameter up to (and including) five (5) inches in diameter, and exceeding 18 inches in length.

(B) All piles shall be created so the material will not roll downhill during burning. Teepee-style piles will not be accepted.

(C) No pile shall be less than 5 feet in height, 6 feet in width and 6 feet in length. Pile size will be considered unsatisfactory if the pile, after 7 days of being piled is less than the minimum standards stated above. Pile height will be measured at the midslope portion of the pile, and pile width and length will be measured at a point on the pile approximately 3 feet above the ground surface.

(D) All piles must be compact. Aligning the material parallel with the slope of the land and placing heavier material on top of the pile should accomplish the compaction of the piles.

(E) All material placed in the pile shall be contained within the general contour of the pile. Trimming of the piles will not be required unless the material extends more than 18 inches beyond the general perimeter of the pile. The material that is trimmed will be placed back onto the pile.

(F) The piles will be located 10 feet outside the dripline of the trees and at least 5 feet from all stumps and down logs.

(G) Waterproof paper or 3-mil plastic shall be placed towards the top of the pile, approximately 3 feet up from the base. The minimum size of the paper (or plastic) shall be 3 feet by 3 feet

C-7.5. TASK: Contractor shall prepare and submit the following data, reports and plans:

1. Quality Control Plan (QCP) - The Government will evaluate the QCP to assure it meets the Tasks and critical sub-tasks of the contract. The plan must demonstrate how the Contractor shall assure quality performance, including the following:

a.

How quality will be monitored through an inspection system covering all services stated in the performance standards. The inspection system must be sufficient to represent work completed on the entire unit.

b.

How the work will be supervised.

c.

How monitoring will result in quality performance and customer satisfaction.

2. Inspection reports–

a. Current inspection results will be maintained.

b. Legibly written, inspection reports will be delivered to the Contracting Officer’s Representative (COR) upon completion of each unit or weekly. By submission of inspection reports, the Contractor is certifying that each unit is satisfactorily completed.

SECTION E - INSPECTION AND ACCEPTANCE

E-1

GOVERNMENT QUALITY ASSURANCE INSPECTION

The Government will conduct quality assurance inspections to determine compliance with contract specifications, performance standards, provisions, Unit Data Sheets, and Exhibits and to provide the basis for computing the rate of payment. Each unit will be verified separately and inspection results on one unit will not be averaged with those of other unit. If Government quality assurance inspection (Attachment 1) reveals quality below the acceptable quality level (AQL), then the Government may conduct a full inspection. Determination of the acceptability of the work performed will be based on this full inspection and will be considered conclusive.

E-2

REINSPECTION UPON CONTRACTOR’S REQUEST

(a) If the original quality assurance inspection results are unacceptable to the Contractor, a re-inspection may be requested. Requests for re-inspection must be made in writing within five days after receipt of initial inspection results. The same inspection procedure will be used, as described in Attachment 1, but new plots will be selected. The inspection pattern will be shifted so new inspection plots will not overlap previously inspected plots.

(b) If the results of the Government’s full inspection procedures are within plus or minus 5 percent of the Contractor’s original inspection results, the Contractor’s results will be used for pay purposes. The Contractor will not be liable for the inspection conducted by the Government.

(c) If the results of the Government’s full inspection procedures differ more than 5 percent either higher or lower, the Government’s inspection results will be used for pay purposes. The Contractor shall be liable for the inspection conducted by the Government.

Standard rounding rules will be used in determining percentage discussed in this section.

E-3 ACCEPTABLE QUALITY LEVEL

(a) Acceptable Work – The acceptable quality level (AQL) for thinning, lopping, scattering, girdling, and hand piling shall be 90% or greater.

(b) Non-Acceptable Work – When the thinning, lopping, scattering, girdling, and hand piling quality falls below 90%, work is considered unacceptable and must be reworked. If excess trees and slash treatment constitute any part of the unacceptable work, payment will not be made until the excess slash height has been corrected. If deficient trees are the cause of quality below 90%, refer to Section G for payment. Inspections after rework shall be made in the same manner as the first inspection but on different plot lines. After 1 rework, Administrative costs shall be the responsibility of the Contractor.

SECTION F – DELIVERIES OR PERFORMANCE

F-1 FAR 52.211-10 Commencement, Prosecution And Completion Of Work (APR 1984) The contractor shall be required to (a) commence work under this contract within 7 calendar days after the date the contractor receives the notice to proceed, (b) prosecute the work diligently, and (c) complete the entire work ready for use not later than the date listed on each task order.. The time stated for completion shall include final cleanup of the premises.

Contract Period

The period of the contract will be identified in the Task Order.

F-2 Contract Time Contract time, whether stated in terms of calendar days or a completion date, will include allowances for inclement weather, fire closures and seasonal shutdowns. Contract time will run continuously from issuance of task order to task order without suspension during periods when no work can be performed.

F-4 Operating Restrictions Contract operations shall be prohibited when:

(a) Industrial Fire Precaution Levels (IFPLs) prevents work from proceeding. Reference, “Fire Protection and Suppression”, R6-FS-6300-52 contained herein.

(b) Seasonal restrictions for wildlife (or other resources) as follows and/or stated on the Unit Data Sheet(s) for specific units:

3. Units within Elk Calving areas shall not be worked from May 15 to June 30.

4. Units within Raptor Nest Area shall not be worked from March 1 to August 1.

5. Other project specific restrictions may be included on unit data sheets associated with task orders.

(c) Snow depth exceeds 8 inches on the ground.

SECTION G – CONTRACT ADMINISTRATION

G-1 Designation of Contracting Officers Representative

The COR is responsible for administering the performance of work under this contract. In no event, however, will any understanding, agreement, modification, change order, or other matter deviating from the terms of this contract be effective or binding upon the Government unless formalized by proper contractual documents executed by the contracting officer prior to completion of the contract.

The Contracting Officer should be informed as soon as possible of any actions or inactions by the contractor or the Government which will change the required delivery or completion times stated in the contract, and the contract will be modified accordingly (This does not apply to individual task assignments which were issued by the COR provided they do not affect the delivery schedule or performance period stated in the contract).

On all matters that pertain to the contract terms the contractor must communicate with the Contracting Officer. Whenever, in the opinion of the contractor, the COR requests effort outside the scope of the contract, the contractor should so advise the COR. If the COR persists and there still exists a disagreement as to proper contractual coverage, the Contracting Officer should be notified immediately, preferably in writing if time permits. Proceeding with work without proper contractual coverage could result in nonpayment or necessitate submittal of a contract claim.

G-2 AGAR 452.215-73 Postaward Conference (NOV 1996) A post award conference with the successful offeror is required. It will be scheduled within 15 days after the date of contract award. The conference will be held at the Ochoco Forest Supervisor’s Office, 3160 NE Third St., Prineville, OR.

G-3 Contractor's Representative Before work starts, preferably at the prework conference, the Contractor shall designate in writing the person or persons who will represent and act for Contractor in Contractor's absence from the job. In the designation, the Contractor shall describe the areas of responsibility assigned to the representative(s).

G-4 Contractor Or Representative On The Job The Contractor or authorized representative shall be on the project area where work is in progress. In the absence of the Contractor, Contractor's authorized representative shall receive orders and instructions from the COR and take such action as is required to keep the job in progress under the terms of the contract.

G-7 Method Of Measurement The acreage was determined by using Global Positioning Systems (GPS).

G-8 Method Of Payment

When the Government quality assurance inspection indicates a difference of less than 5 percentage points (plus or minus) of the Contractor's inspections, the Government will base payment on the Contractor's inspection percentages.

If the Government quality assurance inspection indicates a difference of more than 5 percentage points (plus or minus) of the Contractor's inspections, the Government will base payment on the Government’s quality assurance inspection.

(a) Payment for Thinning, bucking, lopping, scattering and girdling (ITEMS 01A & 02A).

The pay rate will be calculated by multiplying the inspection percentage for each unit times the contract unit price. When the percentage of satisfactory work is 90 percent or greater, payment will be made at 100%.

(A) No more than 100% payment will be made for any one unit

(B) When thinning/slash treatment quality falls below the acceptable quality level (AQL) of 90% due to excess trees or incomplete slash treatment, work is considered unacceptable and must be reworked. If after 1 rework, the percentage of satisfactory thinning is between 70% and 89%, payment will be made by the actual percentage. If the percentage is less than 70%, the work is unacceptable and no payment will be made.

(C) Bucking, lopping and scattering will be considered incidental to thinning and no separate payment will be made.

(b) Payment for Handpiling -

When the percentage of satisfactory work meets the acceptable quality level (AQL) of 90% or greater, the payment will be made at 100%. Work falling below AQL is unacceptable and must be reworked.

Payment method will be specified in task order, examples include:

ITEM 01 - Payment will be based on the number of piles constructed in each unit satisfactorily completed and accepted. Piles not meeting the performance standard and contract specifications shall be reworked and accepted prior to payment. Payment will be negotiated for hand-piles that are larger or smaller than the contract specifications. For example, for piles ½ the specified size, payment will be ½ the price quoted in the Schedule of Items. For piles twice the specified size, payment will be 2 times the price quoted in the Schedule of Items. For piles that are less than ½ the specified pile size, no payment will be made for those piles.

ITEM 02 – Payment will be based on the price per acre for each unit satisfactorily completed and accepted. Piles not meeting the performance standard and contract specifications shall be reworked and accepted prior to payment. Payment will be based on the unit price as quoted in the Schedule of Items.
