INSPECTION AND ACCEPTANCE FAR 52.252-2 Clauses Incorporated by Reference (FEB 1998) This contract incorporates one or more clauses by reference, with the same force and effect as if they were given in full text. Upon request, the Contracting Officer will make their full text available. Also, the full text of a clause may be accessed electronically at this/these address (es): www.aquisition.gov/far/ FEDERAL ACQUISITION REGULATION (48 CFR CHAPTER 1) CLAUSES 52.246-4 Inspection of Services--Fixed-Price (AUG 1996) E.1 Sampling Plots. At least one percent of each treatment area will be sampled by a random series of plots distributed over the entire area. Plot size will be: 1/50 acre E.2 Specific Inspection Procedures The Contracting Officer will make visual inspections while work is in progress for compliance with the terms of the contract. Additionally, the Contracting Officer may make a systematic inspection using 1/50th acre (16.7 foot radius circle on a horizontal plane) plots to calculate an inspection quality based on application coverage and crop tree damage. Plots will be selected randomly and will not overlap. Sufficient plots will be taken to achieve a 1% sample of the treatment area (i.e. 1 plot for every 2 acres). Results will be recorded on inspection forms. The quality of application coverage will be determined by observing the indicator dye or colorant on the target vegetation surfaces. To determine this, the inspection plots will be divided into four (4) quadrants on cardinal directions (North, South, East and West). Each quadrant will be examined for coverage. If more than 90% of the target vegetation surfaces within the quadrant have been treated to specifications, it will be considered acceptable. To determine the percent satisfactory coverage, the number of acceptable quadrants will be divided by the total number of quadrants examined, then multiplied by 100 to give a percentage. For example, out of a total of 30 plots examined (120 quadrants), 112 quadrants received acceptable coverage: FORMULA: 112 / 120 x 100 = 93 % Tree damage will be determined by inspecting each crop tree on the inspection plot. Crop trees will have unacceptable levels of damage if the following occurs: Herbicide mixture or damage on more than 25% of the green crown. Evidence of any amount of herbicide or damage on the terminal leader. Any mechanical damage to the bole, limbs, or terminal leader of the tree. Tree damage will be determined by dividing the number of damaged trees by the total number of trees in all inspection plots. Percent of damaged trees in excess of 5% will be deducted from the inspection quality. To calculate inspection quality, inspection plots will be grouped by stand, and then stands will be grouped in order of treatment until the total number of plots equals or exceeds 30. An inspection quality percentage will then be calculated for each such group. Results will be rounded to the nearest whole percent. EXAMPLE INSPECTION QUALITY CALCULATION: Inspection of two stands yields 25 and 15 plots respectively, which are then grouped to exceed 30 plots. In the total of 40 plots, 152 of 160 quadrants are acceptable, and 12 of 200 crop trees are damaged. The overall inspection quality would be calculated as follows: Application coverage = 152 / 160 X 100 = 95% Crop tree damage = 12 / 200 X 100 = 6% - 5% = 1% deduction Inspection quality = 95% - 1% = 94% Inspection results will be available to the contractor upon request. E.3 Acceptance Work on this contract will be deemed acceptable when the government’s visual inspections show acceptable performance and sample plot data indicate a work quality of 90% or higher. The following clauses which affect acceptance are incorporated by reference in Section I: Responsibility for Supplies, Clause 52.246-16 Use and possession, Clause 52.236-11 E.4 Government Inspections Government inspections are for the purpose of satisfying the Government that the services are acceptable and do not relieve the Contractor of the responsibility for maintaining quality control. The Contracting Officer's Representative or designated inspector will conduct all inspections. The Contractor (or designated representative) is encouraged to be present to observe inspections. Summary results will be made available on request. Compliance Inspections: Visual compliance inspections will be made on a periodic basis. Such inspections are not final and do not constitute acceptance by the Government. Final Inspections. Final (formal) inspections for payment will be made on completed sub-items only. Contractor shall request final inspections in writing and give the Forest Service at least two working days advanced notice. Inspections will be completed within four working days after the notice is received if the work is not ready for inspection at the time specified by the Contractor, the cost associated with the inspection attempt may be charged to the Contractor. Disputed Inspection The Contractor may request reinspection without rework if the results are unacceptable. Reinspection must be requested in writing within 48 hours after receiving written notice of the inspection results. Reinspection will be accomplished within five working days after receipt of the contractor's written request. The same sampling and inspection procedures will be used, but new samples will be taken. The inspection pattern will be shifted so that new samples will not overlap previously inspected samples. Results will be rounded to the nearest whole percent. If reinspection results are within five percentage points of the first inspection, the original inspection result will be used in determining acceptability and payment. If reinspection results are greater than five percentage points above or below the first inspection, the reinspection results will be used. If the reinspection results are within five percentage points of the first inspection, the Contractor shall pay the actual costs of the reinspection. Reinspection after Rework Where rework after a failed inspection may improve the inspection results, the Contractor may rework the area and request (in writing) a second inspection. The Government will charge to the Contractor the cost of this additional inspection. Reinspection will be accomplished within five working days after the notice is received. The results of the second inspection will be final, and no further rework will be permitted. Areas not ready for reinspection at the time specified by the Contractor will not be reinspected, and the results of the first inspection will be final.
