SPECIAL CONDITIONS

Any special conditions will be noted on site map and prescription.

Inspection and Acceptance

1. GOVERNMENT INSPECTION

The Government will perform quality assurance plot inspections to determine compliance with contract specifications. Inspections will consist of observations of work while it is being performed as well as random plots described above in the Government Quality Assurance and Surveillance Plan. The Contractor or a designated representative is encouraged to observe inspections while they are underway.

The Contractor may at any time after award request re-measurement of any site. The request must be made in writing within 5 calendar days after receipt of the Government’s quality assurance inspection results. The request shall include documentation of the Contractor’s reason to believe that an error exists. The same inspection procedures will be followed, but different plots will be measured. If the results of the re-inspection differ by more than 5 percent of the original quality control results, the re-inspection results will be considered acceptable and used for payment. If results of the re-examination are within 5 percent of the original quality control results, the Contractor will be assessed the costs incurred by the Government that are directly related to the performance of such service.

2. REWORK

If the treatment quality as determined above is between 75 and 90% the COR will immediately notify the Contractor by phone or in writing. If the unsatisfactory treatment is due to correctable work (i.e., missed or incompletely released trees, cutting methods, brush, slash, etc) the contractor may rework the unit at his discretion in order to achieve full pay. If it is due to non-correctable work (i.e. over cutting, damage, leave tree selection) or contractor does not correct work, payment will be made at the percentage rate multiplied by the contract unit price.

If the percentage of satisfactory treatment falls below 75% the Contracting Officer will immediately notify the Contractor in writing. If the unsatisfactory treatment is due to correctable work (i.e., excess trees, cutting methods, brush, slash, etc.) rework will be required. If it is due to non-correctable work (i.e. over cutting, damage, leave tree selection) no payment will be made.

If the quality of treatment is not raised above the 75% minimum acceptable standard within (2) work days after receipt of notice in writing from the Contracting Officer of unsatisfactory work, the Contractor's right to proceed may be suspended for noncompliance. Repeated failure to perform work at or above the 75% level may also be considered reason for contract termination.

Any Government quality assurance assessment needed due to the Contractor reworking an area, either at the Contractor's request or because of unacceptable work (original quality below 75%), will be at the Contractor's expense. The Contractor may be assessed actual damages which may include but are not limited to wages of the COR and Government inspector(s) incurred due to the rework, and the costs of vehicles that are incurred while administering the contract during the rework site.

3. REQUEST FOR INSPECTION

The Contractor shall notify the Government when their work on an individual site has been completed and request that an inspection of their work be performed. This request shall be in writing and state that the Contractor’s inspection of the site has been completed and the work on the site is ready for Government inspection.

4. ACCEPTANCE

Work on individual sites will be accepted following the final inspection by the COR. Work with a 90% quality or better will be accepted at full payment. Sites which have an inspection quality between 75% and 89% will be accepted at a reduced pay rate as indicated in SECTION F – DELIVERIES OR PERFORMANCE. The Government reserves the right to require rework of areas with quality below 90% if deficiencies can be corrected. Work with a final inspection quality less than 75% is not acceptable, and will not be paid for.

QUALITY ASSURANCE SURVEILLANCE PLAN

The purpose of this plan is to provide a quality surveillance plan for Timber Stand Improvement services performed on the Hiawatha National Forest. This plan provides a basis for the Contracting Officer’s Representative (COR) to evaluate the quality of the Contractor’s performance. The oversight provided for in the contract and in this plan will help to ensure that quality levels reach the required levels of performance.

Quality Level: By monitoring the Contractor, the COR will determine whether the performance levels set forth in the contract have been attained.

On-site Inspections: The COR will evaluate the current levels of performance, according to the standards set forth in this contract at the discretion of the COR.

Documentation: The COR will keep a file containing the following:

· Copy of the contract

· All modifications to the contract

· Copy of the COR appointment letter

· All contract correspondence initiated or received by the COR

· Copies of all completed inspection reports, checklists, logs, diaries, contract discrepancy reports and surveillance certifications

· Records of meetings attended

· Copies of processed invoices and receipt documents

Evaluation Methods: The COR will conduct periodic on-site inspections. TSI procedures will be observed and sample plots will be examined to ensure and measure compliance with specifications.

Inspection of Pine Release, Pruning and Crown Thinning Treatments:

Each sub-item as designated in the contract Schedule of Items will be inspected as a separate unit and will not be averaged with any other area for acceptance or payment. 90% of designated leave trees, crop trees, or pruned trees must be treated in adherence to the specifications. Plots size and number can be varied to achieve a one percent sample. The following has been prepared assuming 1/50th acre plots (16.7’ radius).

One plot will be taken for each 2 acres of the unit being inspected.

1. Each plot will be examined to record findings on the items listed below:

a). Number of trees treated correctly b). Total number of trees that should have been treated.

(A / B) X 100 = Percent Quality

2. The number of released or pruned trees that should have been released or pruned will vary by plot because of the range of stocking (plus or minus 50% ), the health of the trees occupying the site and/or the portion of plots occupied by openings. Upon inspection of each unit, the treatment quality expressed as a percentage shall be calculated as follows for each plot, and then the plots averaged and rounded up to get the unit percentage:

Example: Release 109 TPA of White Pine A = Number of trees treated correctly (2) B = Total number of trees that should have been treated. This number could be 1 or 3 (plus or minus 50%) (2) Example: (2/2) X 100 = 100% quality

Inspection of Aspen Cleaning

Each sub-item as designated in the contract Schedule of Items will be inspected as a separate unit and will not be averaged with any other area for acceptance or payment. 90% of designated leave trees or cut trees must be treated in adherence to the specifications. Plots size and number can be varied to achieve a one percent sample. The following has been prepared assuming 1/50th acre plots (16.7’ radius).

One plot will be taken for each 2 acres of the unit being inspected.

1. Each plot will be examined to record findings on the items listed below:

a). Number of trees treated correctly(cut trees and leave trees) b). Total number of trees treated.

(A / B) X 100 = Percent Quality

2. Upon inspection of each unit, the treatment quality expressed as a percentage, and then the plots averaged and rounded up to get the unit percentage:

Example: Aspen cleaning.

A = Number of trees treated correctly (28) B = Total number of trees treated. (30) Example: (28/30) X 100 = 94% quality

Inspection of Cleaning in Uneven Aged Northern Hardwood Canopy Gaps:

One canopy gap per acre will be inspected. A transect will be taken and gaps that fall within that transect will be inspected. Typically 2-6 canopy gaps can be found per acre. Together all canopy gaps inspected will need to meet a quality of 90% or greater.

1. Each canopy gap will be examined to record findings on the items listed below:

a). Canopy gaps should meet all specifications listed above. Up to two (2) trees between 2 feet and 2 inches in diameter not cut will be allowed without failing the gap.

A Number of gaps treated correctly B Total number of gaps sampled

(A / B) X 100 = Percent Quality

2. Upon inspection of each unit, the treatment quality expressed as a percentage for that unit only:

Example: Canopy Gaps for 20 acres Sample of 20 canopy gaps

Inspection of Cleaning Canopy Gaps in Beech Salvage Sales:

One canopy gap per acre will be inspected. A transect will be taken and gaps that fall within that transect will be inspected. Typically 2-6 canopy gaps can be found per acre. Together all canopy gaps inspected will need to meet a quality of 90% or greater.

1. Each canopy gap will be examined to record findings on the items listed below:

a). Canopy gaps should meet all specifications listed above. Up to two (2) American beech between 2 and 4 feet in height not cut will be allowed without failing the gap.

A Number of gaps treated correctly B Total number of gaps sampled

(A / B) X 100 = Percent Quality
