Work to date represents 70% of <br /> the original contract. <br /> Please review the attachment from Barr for more information regarding the proposals. <br /> Explanation: On February 14, 2012 Council authorized the installation of access stairs, access <br /> platforms, safety gates, and conveyors to the 4 iron vessels at Water Treatment Plant #1. <br /> Previously, the iron vessels were accessed via a permanent ladder and narrow access platform <br /> attached to each vessel. This configuration made it difficult to lift and change the filter media in <br /> each vessel. Media is changed twice per year. This project is a significant safety upgrade to the <br /> water treatment plant. <br /> Three access stairs are included in this project to provide access to the four iron filters; one <br /> stairway to Vessel #1, a common stairway to Vessels #2 and #3, and one stairway to Vessel #4. <br /> Two large access platforms are also included in this package; one common platform for Vessels <br /> #2 and #3, and one platform for Vessel #4. Product conveyors will be installed to aid in lifting <br /> the large bags of filter media to the top of the vessels for change out. Conveyors will be installed <br /> for vessels #2, #3, and#4. Due to its location in the plant, an access platform and conveyor will <br /> not be installed for Vessel #1. Media change out will be facilitated by lifting equipment (i.e. <br /> scissors lift). <br /> Costs and Funding: The total cost of this project will be funded from Fund 206 — NBCGRS <br /> Army Water Fund. <br /> Grant M. yffels, . <br /> Director of Public orks <br /> Attachment—Letter from Barr dated April 30, 2012 <br />
