1. Purpose and Intent
The City of Winooski is soliciting sealed bids for one new, current-production tandem vibratory asphalt roller to

limited to, Caterpillar CB2.9, HAMM HD 12 VV/VO, BOMAG BW 120 AD-5, Dynapac CC1200 VI, Wacker Neuson
RD28-120/RD28-120o, or approved equal.

6. Bidders may identify Sourcewell, state contract, or other competitively solicited cooperative purchasing pricing as
an alternate. Any such proposal shall identify the contract name/number and clearly show the City's net price.
7. The City reserves the right to reject any or all bids, waive minor informalities, request clarification, and select the
bid determined to be in the best interest of the City, considering price, compliance, service support, warranty,
delivery, and lifecycle value.
8. A product demonstration is strongly preferred and may be requested prior to award. The City prefers to evaluate
