Ash Tree Treatments

The City of Sun Prairie's Parks, Recreation & Forestry Department is seeking proposals for trunk injection treatments of ash trees using Emamectin Benzoate to combat Emerald Ash Borer infestation. The project encompasses treating approximately 471 ash trees citywide, with a total estimated diameter breast height (DBH) of 6,531 inches. Contractors must provide all labor, supervision, equipment, services, and expertise to perform the treatments using a 4% micro-encapsulated liquid formulation of Emamectin Benzoate, with no product substitutions allowed. Qualified vendors must use approved injection devices (Automatic Micro-injection, Micro-infusion, or Manual Micro-injection) with self-sealing plugs and must possess a valid Wisconsin Commercial Pesticide Applicator's License. The RFP was issued on April 17, 2020, with proposal questions due by April 20, 2020, and answers posted on April 23, 2020. Proposals are due May 1, 2020, at 2:00 PM CST, with the contract term running from May 20, 2020, to June 15, 2020. Evaluation criteria include cost (50 points), applicator qualifications (15 points), proposal quality (15 points), similar project experience (15 points), and local vendor preference (5 points).

The solicitation includes a local vendor preference for businesses with physical addresses within Sun Prairie city limits. No specific set-aside designations for disadvantaged enterprises are mentioned in the documentation. Contractors are prohibited from subcontracting and must maintain comprehensive insurance coverage, including Workers' Compensation, Commercial General Liability ($1,000,000 per occurrence), Automobile Liability ($1,000,000), and Umbrella Liability ($5,000,000), with the City named as an additional insured. The City reserves the right to extend the contract for one year under the same or more favorable terms, with potential pricing adjustments based on the Consumer Price Index. If budget constraints arise, the treatment list may be divided across two years, with half the trees treated in 2020 and the remainder in 2021, contingent upon satisfactory contractor performance. Pricing will be submitted on a per-DBH-inch basis, with billing based on actual field measurements rather than estimated quantities. While no specific budget range is provided, the project involves treating 471 trees with precise chemical application requirements.
