Project: Grand Avenue Park Bridge <br /> Change Order No.: 21 <br /> Change Order Effective Date: 12-06-2019 <br /> CONTRACTOR <br /> L <br /> By �,21)( <br /> Officer Date: March 25,2020 <br /> Exhibit A—Description of Changed Work <br /> ADA Deck Changes: <br /> 1. The upper and lower bridge decks were designed at a 4.9% longitudinal slope. There was no <br /> camber designed into the bridge. When the bridge was set, it sagged slightly in the middle <br /> approx. 3" over the 270' span. This was enough for the longitudinal slope to be over 5.0% <br /> along the eastern portion of the bridge. The majority of the decks had been formed and rebar <br /> was being installed. The least cost solution was to pour the finish surface in a series of ramps <br /> and landings that met ADA guidelines. This was required for the entire upper and lower deck. <br /> The transition ramp was designed for ramps and landing per original contract. This change <br /> order covers the additional work to form,pour and strip the modified decks. There were 4 <br /> additional pours required and the duration extended over a month to accomplish the bridge <br /> decks. <br /> Exhibit B—Additional Contract Time: <br /> This change order adds 20(twenty)working days to the contract. <br /> Exhibit C—Existing and New Bid Item(s) <br /> See attached for new bid item. <br /> Submittals <br /> N/A <br /> Measurement and Payment <br /> Time and material was tracked between City of Everett inspector and Interwest Superintendent.
