MEETING Meeting Date: 08/19/2020 Subject: Authorize Change Order No.11 to the BAWA 6 MGD Surface Water Treatment Plant Prepared For: Andrea Brinkley, Public Works/Engineering/BAWA Prepared By_ Linda Newsted, Public Works/Engineering/BAWA Information ITEM Consider a resolution authorizing Change Order No. 11 with Pepper Lawson Waterworks, LLC, for the BAWA 6 MGD Surface Water Treatment Plant. PREFACE The Baytown Area Water Authority ("BAWA") and the City of Baytown (the "City") approved the contract with Pepper Lawson Waterworks LLC, ("PLW") for the construction of a 6 MGD Surface Water Treatment Plant (the "Project") in May 2018. The project is on schedule, and items related to the completion of certain critical items of work related to the completion of the Operations building as well as life, safety and code issues must be addressed at this time. These items are a part of Change Order No. 11, in the amount of$188,216.36. A list of the work to be performed is described below in the following items: 1. The first item of work is an increase in the amount of$9,026.801 to add and configure the City of Houston flow meter signal to provide signal information to the Fritz Lanham Surface Water Plant. BAWA staff monitors the daily flow of raw water provided by the City of Houston via the canal, and this will allow staff to access the information in addition to the City of Houston. 2. The second item of work is an increase in the amount of$169,163.74 to re-route the chemical containment and storm drain lines away from the sanitary sewer lift station, and direct flows to the sludge lagoon. This is consistent with the Fritz Lanham Surface Water Plant, and with code. 3. The third item of work is for an increase in the amount of$4,120.38 for the Elevator shunt trip disconnect, which is required by the fire code, and not included in the original design documents, but identified during the state elevator inspection. 4. The fourth item of work is for an increase in the amount of$5,905.44 for the addition of protective separation basins to contain and maintain separation of the sodium chlorite and hydrochloric acid stored in the chemical containment area at the Operations building. The two chemicals are extremely corrosive and present a health and safety issue, if not separated and any leaks were to cause a mixing of the chemicals. This was not included in the design drawings. These changes are summarized below in the following chart: 11.1 City of Houston Flow Meter Signal 1 LS 95026.80 Modifications (PCO 073) 11.2 Drain Line Modifications (PCO 074B) 1 LS 169,163.74 11.3 Shunt Trip Disconnect for Elevator (PCO 075) 1 LS 4,120.38 11.4 Chemical Vat Separators (PCO 077) 1 LS 5,905.44 TOTAL $1889216.36 RECOMMENDATION agendas.baytown.org/live/publish/print_ag_memo.cfm?seq=19223&rev num=0&mode=External&reloaded=true&id=0 1/2 8/13/2020 Print Agenda Item Request Staff recommends approval.
