SECTION I – DESCRIPTION OF WORK:

The objectives of this project are to meet stewardship requirements, increase forest health and vigor, and reduce hazardous fuels in order to reduce the threat of catastrophic wildfire by accomplishing the following:

1. Haul slash pile material from 18 pre-existing timber removal landings.

2. Hand cut and scatter brush and small trees to change the fuel profile from vertical to horizontal.

3. Hand cut and pile for burning brush and small trees to reduce the surface and ladder fuel load.

4. Masticate brush along high usage roads to maintain visibility and public usage.

5. Decommission spur roads.

SECTION II – WORK ITEMS

Mandatory Item 1: Open / Close 18 Landings Biggie IRTC Units 1, 2, 3, 4, 5, 8, 10, 16, 17, 43, 81 (Avg. spur road length 100 feet) Remove barriers and open any roads or landings currently closed for access to slash pile locations prior to performing work on Item 2. Spur roads accessing piles range in length from 50-200’, averaging 100’; landings with slash piles range from 1-2 acres in size.

Close by ripping landings and road after completion of work. Closing includes erosion control, i.e. replace water bars, outslope landing for drainage, till access road, and replace large berms, root wads, or other barriers if used. Till to a maximum depth of 24” and close access into landings and any native surface temporary roads that access landing locations after work is complete.

Mandatory Item 2: Remove 18 slash piles Biggie IRTC Units 1, 2, 3, 4, 5, 8, 10, 16, 17, 43, 81 (1,760 Tons) Remove all slash pile material meeting utilization standards as outlined in Division A, Appendix B at 18 existing landings. Any remaining slash not meeting specifications, shall be spread to a depth no greater than 12”.

Manually cut brush (> 6.0” in height) and small conifers (1.0 – 5.9” dbh), lop, and pile to be burned in piles ≤ 10’ in diameter and ≤ 6’ in height. All woody debris, including preexisting downed woody debris, shall be piled except for that which must be left in place to meet approx. 15 tons of 15”+ dbh coarse woody debris per acre.

Technical Specifications for Optional Items 3, 4, 6 and 7:

Live non-commercial trees will be cut and piled or scattered in the woods by hand according to the specifications described below.

Hand Thinning:

· Retain healthiest, full-crowned, damage-free, largest and least-represented dominant and co-dominant conifer leave trees.

· Maintain an average spacing of 10-15’ between crowns (plantations) or 20-25’ (natural stands). Spacing can vary up to 50% to promote mixed-conifer species composition and heterogeneity. Include overstory trees ≥ 10.0” dbh toward residual spacing if they are healthy and vigorous; do not allow for crowns to overlap.

· If an overstory of large healthy conifers and hardwoods exists (trees ≥ 10.0” dbh) which meets spacing requirements, remove all material ≤ 9.9” dbh (≤ 5.9” dbh in item 7).

· Species preference for retention, in order from most to least desirable, is healthy Sugar Pine, Ponderosa Pine, Douglas-fir, and Incense Cedar over White Fir. Do not cut Giant Sequoia.

· Remove all conifers according to item-specific dbh upper-limits within 15’, and up to 35’ from the south-southwest portion, of the drip line of live hardwoods ≥ 10.0” dbh.

· Unless otherwise agreed, maximum cut stump and brush stub height shall be 6.0” (measured uphill or above natural obstacles).

· Do not damage residual trees; sub-merch trees damaged beyond recovery by contractor’s operations will be cut and removed.

Hand Piling:

Location of Piles:

· Do not leave cut material sitting against or hung in any leave tree, or outside of unit boundary.

· Piles shall be a minimum of 10 feet from the crown or drip line of any tree or in the least impactful location among standing live trees; piles shall be placed outside of any riparian buffer.

· Piles shall be located a minimum of 25 feet from protected improvements (including but not limited to fences, gates, signs, water lines or tanks), existing structures, or metal-banded or -tagged trees; piles shall not be placed within the 100’/ 50’/ 25’ perennial/ intermittent/ ephemeral riparian buffer.

· Piles shall be placed so they are not on top of logs, stumps, fire lines, or channels.

Construction and Size of Piles

· All cut material ≥ 3’ in length and 4.0” in diameter shall be piled in compact hand piles at least 4’ in diameter and height and not to exceed 10’ in diameter and 6’ in height unless otherwise approved by the contract administrator.

· Piles shall be constructed in a manner which provides for rapid ignition and complete consumption of all piled material.

· Each pile shall be constructed by stacking limbs, stems, cut boles and other slash on the pile so as to be parallel to the slope to reduce roll-out and maintain compactness, and in such a manner that they are stable and will not fall over. Avoid ‘teepee’ style piling unless otherwise directed by contract administrator.

· When piles are built on slopes greater than and equal to 25%, a trench 12” deep and 12” wide at surface will be excavated on the downhill side of the pile to catch rolling material. Depending on consultation, the individual pile trenches may be substituted by a fire line trench spanning the lower (downhill) outside edge of the unit boundary. In this instance, a berm shall be constructed on the outer edge of the trench to provide 18” height difference between the bottom of the trench and the top of the berm.

· All piles shall be trimmed, with trimmed pieces stacked parallel on each pile.

· Each pile shall be covered with 4mm plastic sheeting covering at least 50% of the pile. The plastic will be placed once ¾ of the pile is constructed, with the final ¼ securing the plastic in place. Contractor shall furnish plastic sheeting.

· Where slash produced by operations is too nominal to construct a pile of minimum size (i.e., low stand density, single trees), slash will either be dragged from within a 20’-30’ radius to create a pile or dragged and incorporated into an existing pile within the same radius. In cases where these standards cannot be met, the cut trees will be limbed, bucked, and scattered to a height of less than 6” above the ground.

Lopping and Scattering:

· Cut and scatter hand thinned material (brush ≥ 6.0” height and conifers 4.0” - 9.9”).

· Completely limb felled trees; boles and limbs shall be cut into pieces not to exceed 3’ in length.

· Scatter cut material on forest floor inside unit boundaries and outside riparian buffers. Scattered material depth will not exceed 18”. Material will not be piled or left to lean against leave trees.

Specifications Applicable to Multiple Work Items Above:

· Equipment shall be furnished on a fully operational basis, of modern design, and in good operating condition, with a competent, fully qualified operator.

· The contractor shall furnish all fuel, lubricants, personnel, fire tools and suppression, and supervision necessary for the operation of the equipment and completion of the project work.

· If, during the Agreement? Contract? period, the equipment requires repairs before operations can continue, it shall be the responsibility of the contractor to complete such repairs.

· The contractor shall provide for public safety when operating equipment within 300 feet of open roadways and designated trails by posting cautionary signs warning of hazardous work ahead. Refer to Appendix E Attachment 1B (Traffic Control) for details. Refer to Traffic Control Plan for details

SECTION III – CONTROL OF WORK

The Contractor agrees to conduct its operations under this contract and other related business activities in compliance with Federal, State, and local statutes, standards, orders, permits and other regulations.

The Contractor shall meet all State and local environmental quality laws applicable to National Forest system lands.

Nothing below shall be construed to take away any of the Government’s rights under the Suspension of Work Clause (52.242-14). Work may be performed at any time during the term of the contract, except under the following conditions:

(1) When conditions are such that operations shall be restricted or ceased due to increased fire risk (refer to Fire Plan).

(2) When winter recreational opportunities would be disrupted by operations. As a result, no operations will be permitted from December 1 – March 30, unless otherwise agreed to by the Forest Service in writing.

When seasonal operating restrictions (Limited Operating Period) for California Spotted Owl PACs are in effect. All areas of restriction are shown on the Project Map as designated LOP boundaries and listed in the solicitation. See Appendix B.

Restrictions would apply:

(3) If new nesting sites are discovered,

(4) When soil moisture conditions create excessive risk of damage to the soil or roads; equipment may operate when soils are dry to a minimum depth of 4 inches,

(5) When snow depth creates a situation where requirements cannot be met and/or work cannot be inspected, as determined by the COR.

(6) The government reserves the right to prioritize the order in which Units are treated.

(7) If any cultural or archeological sites are discovered during operations of this contract, work will be suspended in the immediate vicinity of the site until a reconnaissance survey is completed by the Forest Archeologist. Areas excluded from treatment shall be deleted from the contract.

(8) If any protected frog is found at any time during implementation of this Project, cease operations in the vicinity of the frog, vacate the immediate area and leave the frog alone. If possible, take a photograph of the frog as follows: top looking down, and side view. No activity will occur in that area until such time as the frog has vacated the area on its own volition. With the exception of a U. S. Fish and Wildlife Service approved biologist, do not handle these frogs. Report the occurrence as soon as possible to the Partner and Forest Service.

(9) Chainsaw Operations (thinning) are limited to Monday through Saturday, unless otherwise agreed to by the Partner and Forest Service. No work on Sundays or Federal Holidays.

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.

Throughout the life of the project, the Forest Service will be responsible for continuing field inspection and control of operations and accountability requirements.

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/portion of a work item (e.g. each individual slash pile, totaling 18, for work item 2) 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 or on a plot basis (see below). In the event visual inspection indicates work to be in non-compliance with specifications, prompt corrective action and/or rework shall be required. The Contractor or field representative is encouraged to observe the inspection and will receive summaries upon request.

4. Findings shall be documented for the project record and project work deficiencies will be corrected by appropriate action.

5. When inspection results are below 95% and excess trees contribute significantly, acceptance will not be made until the excess tree deficiency has been corrected. Final inspections shall be performed in a manner that will not unduly delay work. Inspection acceptance will be based on adherence to the requirements stated in the Specifications.

Government Inspection Procedures – Formal (Plots) (Items 3, 4, 6, 7)

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 a random grid 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 grid on a unit map.

6. The minimum number of verification plots, per treatment unit, shall be as follows:

Unit Acreage Minimum No. of Plots

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 trees to be left on plot (based on spacing requirements).

c. Number of trees left on plot.

d. Number of deficient trees/lopped slash segments (item 4).

e. 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

Unsatisfactory Cutting

1. If the work quality falls below 85 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 85 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 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.

Government Inspection Procedures – Items 1-6

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

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 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 map(s) 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 – Item 1 and 2 - Opening / Closing of Landings and Remove Slash Piles

1. If informal visual inspection indicates acceptable work quality, the Contractor will be paid 100 percent of their bid rate.

2. If informal visual inspection indicates unacceptable work quality, the Contractor will be given an opportunity for rework, made in writing or made orally and recorded on a daily inspection diary.

3. COR will determine allowable number of reworks.

Acceptance and Payment – Item 3, 4, 6, and 7 – Hand Thin and Pile for Burning or Lop and Scatter

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 95 percent or higher, 5 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 94 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.

Acceptance and Payment – Item 5 – Roadside Brushing

1. If informal visual inspection indicates acceptable work quality, the Contractor will be paid 100 percent of their bid rate.

2. If informal visual inspection indicates unacceptable work quality, the Contractor will be given an opportunity for rework, made in writing or made orally and recorded on a daily inspection diary.

3. COR will determine allowable number of reworks.

Acceptance and Payment

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

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

3. Payment rate for work quality at or above 85% will be calculated as follows:

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

4. 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 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

(c) 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

* Stewardship Credits will be earned first, whenever practical. Forest Service Funds will be used if the availability of Stewardship Credits is exhausted or if appropriated dollars are obligated to a specific item.
