Spink County Weed Spraying

The contract pertains to weed spraying services in Spink County, South Dakota, under the oversight of the South Dakota Department of Transportation. The scope involves controlling noxious weeds and unwanted vegetation along highway rights-of-way through targeted herbicide applications, primarily during spring and late summer/fall, with a focus on vegetation under eight inches in height. Contractors are required to use specified herbicides including Glyphosate, 24D, Tordon, Polaris, and others, applied with a minimum of ten gallons of water per acre, while maintaining a three-foot clearance around signposts and guardrails. All work must comply with AASHTO M 180, the Clean Air Act, the Federal Water Pollution Control Act, and USDA-approved labeling standards. Safety protocols mandate the use of flashing amber lights during operations, and adherence to ADA requirements is mandatory. Performance is confined to designated areas within Spink County, with deliverables including labor, equipment such as ATV sprayers and trucks, and all necessary materials. The contract is structured as a firm fixed price arrangement with a total estimated value of $46,043, based on unit pricing for herbicides, labor, and equipment usage, including 20,000 oz of 24D, 1,500 oz of Glyphosate, and 600 hours of labor at $28 per hour. Bids must be submitted using the standardized DOT-123 form, completed in ink and notarized, with no electronic file uploads permitted for proposal submission—only sealed paper packages delivered by the specified deadline of April 23, 2026, at 1:30 PM. Compliance with non-discrimination statutes under Title VI and the ADA, South Dakota’s constitutional restrictions on legislative conflicts of interest, and state-mandated wage rates is required, with certifications affirmed by the offeror. Invoicing is manual, submitted to the Area Engineer or Maintenance Supervisor with DOT 820 forms, and paid through state appropriation codes i85M through i85Q under FY26 Contract Maintenance. There are no option periods, escalation clauses, or formal contract modifications outlined beyond change orders for unlisted herbicides. Evaluation of bids focuses on accurate unit pricing, complete form compliance, and absence of bid rigging, with award made at the department’s sole discretion, suggesting a price-dominant selection process. Environmental and regulatory compliance is non-negotiable, with violations potentially leading to sanction or contract termination.
