Backpack Invasive Plant Treatments Grand Teton National Park

Statement of Work

1.1 Scope of Work

Backpack Spot Treatments This item includes defined areas where motorized survey and treatment methods are not allowed. Motorized access to jobsite and staging areas will be approved and available;

however, survey and treatment will be conducted by non-motorized methods such as backpack spraying. Treatment with truck handgun and long hoses that can reach into the interior of a given project area may be allowed, depending on jobsite, and will be described in individual order/line item. Price per acre reflects the cost of survey and application of herbicide (treatment), herbicide used, as well as collection of electronic data. This is a requirement for the ground-based survey and application of herbicide to control targeted noxious weeds in Grand Teton National Park, Wyoming.

Equipment to be utilized and treatment methods will vary by site. The Contractor shall furnish all necessary items but not limited to herbicides and adjuvants, materials, equipment, labor, licensing, supervision, transportation, operating supplies and incidentals necessary to safely survey assigned acreage and apply herbicides using ground-operated equipment, in strict compliance with the herbicide labels. Common herbicides and adjuvants may be used and will be described in the scope of work (SOW) for each line. Contractors should submit a list of herbicides to be used to the park before work begins.

Work to be performed by the Contractor includes but not limited to: (a) survey assigned acreages (Sites) for noxious weeds; b) mix and apply specified herbicide(s) to the target weed(s); (c) complete and submit Government provided daily herbicide treatment records;

and (d) the collection of electronic data, which includes track logs that capture travel routes while both surveying and applying herbicide. The individual orders/line items will provide further specifics on the daily herbicide treatment records. Orders/line items will be issued by the Government for work ordered under this contract. Orders/line items will include site-specific descriptions and maps for the work to be accomplished, specify herbicides, adjuvants, and rates to be used, as well as provide additional details that will inform the Contractor of access points, water sources, and other details.

This work is 'performance-based' with multiple contract awards (IDIQ, Base Year and Two Option Years). 'Performance-based' means the Contractor is responsible for an end product/result. If an end product/result is not provided in compliance with the Performance Work Statement (PWS) and contract terms and conditions, rework will be required where possible and/or a payment reduction may result (reference the Quality Assurance Surveillance Plan (QASP) (Attached).

7.0 Performance Requirements Summary

7.1. Contractor Quality Control

The Contractor is responsible for management and quality control actions to meet the terms and conditions outlined herein. The role of the Government is quality assurance to ensure contract standards are met. A Quality Control Plan shall be provided by the Contractor within thirty (30) days of contract award. The Plan shall demonstrate how the Contractor will monitor and inspect the work performed by the Contractor. Once work for a line item has commenced, Quality Control self-inspections will be conducted by the Contractor daily, and records of such must be submitted to the Government weekly.

Records of Quality Control inspections shall be kept and made available to the Government throughout the performance period and for the period after contract completion until final settlement of any claims under this contract.

7.2 Government Inspection and Acceptance

The Government will inspect completed work on each line item by reviewing the self-inspection records and by verifying information in the field. The COR or designated Inspectors may conduct periodic inspections at discretionary times and locations while work is being carried out by Contractor. If, as a result of these periodic inspections, the COR or Inspector has concerns about the Contractor's ability to meet defined Quality Standards, these concerns will be communicated to the Contractor. The Government will conduct a final inspection at the treatment sites at least fourteen (14) days following completion of SOW defined in the line item. The final inspection will be used to look for signs of herbicide damage to the plants (wilting, color change, or stunted growth). A determination of acceptance will be based on discoloration and wilt of the plants through ocular easements within the treatment or inventory area. If initial ocular inspection during the final inspection suggests treatment efficacy of less than 90 percent, monitoring plots will be utilized in order to determine whether quality standards have been met. If it is determined the Contractor has failed to meet the minimum 90 percent affected targeted plants, the Contractor shall rework the area. The SOW will not be accepted until 90 percent of the targeted species show signs of herbicide damage. Failure to meet the 90 percent or greater quality standard will result in reduced payment or non-acceptance (See Sections

7.3 - 7.5).

Additionally, daily treatment logs and electronic data must be submitted within fourteen

(14) days after the completion of the line-item SOW and prior to invoicing. These records and data will be reviewed by the Government to determine accuracy and completeness prior to final acceptance. If monitoring plots are utilized, the location within the treatment area will be at the discretion of the Government. Circular p lots will have a radius of 29.5 feet, which is equivalent to 1/16 acre. The number of plots to be used will be determined on a case by case. Weed kill count within this plot will be determined by ocular estimation of total percent of live versus dead weeds. These observations will be recorded on a monitoring sheet.

7.3 Government Quality Assurance

The purpose of the Quality Assurance Surveillance Plan (QASP) provides a systematic method to evaluate performance for the contract. The QASP explains what will be monitored, how monitoring will take place, who will conduct the monitoring and how the monitoring will be reported. The Government's role and responsibility shall be to oversee and coordinate the monitoring activities among the Contracting Officer, Contracting Officer's Representative and the Inspector(s). The Contractor representative(s) shall at a minimum provide an onsite contract manager (Site Manager), who shall be responsible for all contract requirements and who fully represents the Contractor on all matters relating to the operation of this contract.
