CHANGE ORDER NOTICE - AGR Gypsy Moth Ariel Spraying

This state contracting opportunity from the Illinois Department of Agriculture involves a change order to increase the funding for an existing contract related to the aerial application of insecticides to control the invasive spongy moth (Lymantria dispar) across the state. The original contract, BBREFNO.: 23-406AGR-NATRE-B-32500, required aerial spraying, but the number of acres needing treatment significantly exceeded initial estimates. As a result, the total costs incurred for the program will exceed the maximum amount of the original contract, necessitating this change order to increase the total contract amount by $37,854.31 for a revised total of $495,725.31. The change order explains that aerial application needs are based on trapping results and actual moth populations, which can vary drastically from year to year due to factors such as weather conditions and previous control efforts, making it challenging to accurately plan spray events in advance. In this case, heavy spongy moth populations have required larger spray areas, leading to the need for the contract amendment.

The procurement is limited to the incumbent vendor, Hendrickson Flying Services, as it is a change order to an existing contract. There are no set-aside designations or restrictions on the types of organizations that can respond. The contract amendment extends the original completion date of January 17, 2026, with no changes to the supplies or services to be provided. The total contract value, including this change order, is $495,725.31.
