The evaluation of bids and determination as to equality of the products shall be the responsibility of the City and will be based on information furnished by the bidder or identified in their bid, as well as other information reasonably available to the City.

7 03/2026

If deemed equal, written notification and/or an addendum will be issued prior to bid opening and will be public.

Any modifications may result in the rejection of the proposal and refusal to award the contract by the City.

16. Choice of Law/Jurisdiction: The validity, performance, and enforcement of this Agreement are governed by the laws of the state of South Dakota.
