Corrective action shall be taken immediately by the contractor to insure evenly spaced, straight and regular application paths and complete coverage of areas included in the spraying job. The entire surface within the designated boundaries of the project area shall receive uniform coverage with herbicide except for areas excluded by the Government. Areas excluded from the herbicide operation within the designated boundaries will not be included in the acreage computed for payment. Dispersal shall be low enough to obtain proper distribution and uniform coverage of herbicide. Liquid application shall not be made during a rainstorm, snowstorm, or when the ground is frozen.

The Contractor shall contact the authorized BLM Contracting Officers Representative or Project Inspector (COR/PI) 72 hours prior to implementing any work specified in this contract. Furthermore, the COR/PI shall be present at the prescribed work sites to direct and inspect the Contractor. The Contractor shall submit completed Pesticide Application Records no later than 2 weeks after applying the herbicide specified in this contract.

6.0 FIELD QUALITY CONTROL

6.1 The BLM COR/PI will monitor to determine uniformity of herbicide application. Randomly placed drift cards may be used for quality control testing. If coverage is deemed unsatisfactory (e.g. less than 90% of drift cards show herbicide coverage), the contractor will be required to treat those areas at no additional cost to the BLM.

7.0 EXPECTED DELIVERY OR PERFORMANCE TIMES

7.1 The period of performance is from September 15, 2020 after the first wetting rain/snow event, and will be completed no later than January 31, 2021 (depending on weather and soil conditions), this will depend on the time needed by the Contractor to complete the herbicide application. Government preference is starting and completing the project as quickly as possible, however due to weather conditions during this time, soil moisture, soil temperature, snow cover, and time frames may need to be re-negotiated. Government preference is for application immediately prior to wetting rain/snow event.

7.2 There will be a Pre-Work conference prior to the start of the project at an agreed upon date between the COR/PI and the Contractor. At the pre-work conference the Contractor shall provide the COR a written “work progress” plan that details his/her proposed workforce and schedule to provide for orderly completion of the work within the contract performance times. This work schedule must be acceptable to the government. At a minimum the schedule should reflect a work progress rate equal to the available amount of contract performance time. The unit sequence work schedule will be determined by the COR at the pre-work conference and may be subject to change because of normal variations in weather conditions at no change in contract time or price.

7.3 The Contractor shall begin work within 7 calendar days from the effective notice to proceed. The Contractor shall continue performance of the work under the contract without delay or interruption except by causes beyond his control as defined by contract clauses, or by the receipt of a “Suspend Work Order” issued by the Government. Failure to do so may be cause for action under the “Default” clause. The Contractor shall complete all work required within the time specified.

8.0 MEASUREMENT AND PAYMENT

8.1 Application of liquid herbicide will be measured and paid for by the number of acres treated to the nearest acre.

8.2 Measurement for payment for herbicide treatment will be the actual area, in acres, within the designated boundaries satisfactorily treated in conformance with these specifications. Measurement will be made from either physical surveys of the areas or a computer-generated file created in a GPS Differential Guidance System at the option of the BLM. The shapefile will be used in ArcGIS for final acreage measurement. Acreages will be computed from horizontal distances as shown on maps at the option of the BLM.

8.3 If the quantity of a unit-priced item in this contract is an estimated quantity and the actual quantity of the unit-priced item varies more than 15 percent above or below the estimated quantity, an equitable adjustment in the contract price shall be made upon demand of either party. The equitable adjustment shall be based upon any increase or decrease in costs due solely to the variation above 115% or below 85% of the estimated quantity. If the quantity variation is such as to cause an increase in the time necessary for the completion the contractor may request, in writing, an extension of time, to be received by the Contracting Officer within 10 days from the beginning of the delay, or within such further period as may be granted by the Contracting Officer before the date of final settlement of the contract. Upon receipt of a written request for an extension, the Contracting Officer shall ascertain the facts and make an adjustment for extending the completion date as, in the judgment of the Contracting Officer, is justified.

9.0 CONTRACTING OFFICER’S REPRESENTATIVE (COR) AND/OR

PROJECT INSPECTOR (PI)

The COR and/or Project Inspector (PI) will be appointed by the Contracting Officer upon award of the contract.
