File Number: 20-614 <br />$912,289 for the subject project and authorized the City Manager to approve individual contract <br />change orders up to 5% and cumulative contract change orders up to 15% of the total contract <br />amount. The construction contract includes the repair and replacement of plumbing, deck drains, <br />tile, coping, and the resurfacing of the pool. The project also includes relocation of the mechanical <br />equipment in the pump room to allow for a secure and safe space for chemical storage that will <br />have access restricted to pool staff only and eliminate the mechanical room space being shared <br />with the Boys and Girls Club for storage of their supplies. <br />The project will also install ultra-violet (UV) filtration to reduce the amount of chemicals required to <br />treat the pool water and to decrease the smell of chlorine that is common with indoor pools. To <br />address the Americans with Disabilities Act (ADA) needs of the pool facility, this contract will also <br />replace the entire pool deck slab to provide appropriate surface slopes for everyone’s safety. <br />Construction was approximately 40% complete as of mid-December 2020. There have been <br />several extra work items related to unforeseen deterioration. <br />When the pool deck was demolished, it was apparent that the sanitary sewer line that is used to <br />drain the pool and that also collects water from the pool deck deteriorated such that there were <br />holes in the pipe. Change Order 1 was for the replacement of the sanitary sewer main from the <br />mechanical room, all around the pool deck, and to the point of connection on the Club side of the <br />building. <br />It was also discovered that the electrical conductors to the underwater pool lighting were directly <br />buried in the pool deck and were corroded from contact with the soil. It was also noted that the <br />underwater pool lights were mismatched and old and there was some corrosion to the niches <br />around the lights. Change Order 2 addressed replacing the conductors, niches, and lights. <br />After removal of the existing coping, tile and plaster from the pool it was found that the bond beam <br />at the top of the pool wall had deteriorated, was not structurally sound and was separating from <br />the concrete block pool structure below it. The City authorized removal of the bond beam to allow <br />inspection of the pool wall. This work was completed as Change Order 3. <br />The cost for replacing the bond beam around the entire pool was received. As the cost exceeds <br />the 5% individual change order authority, City Council approval is requested. A summary of costs <br />is included in the Change Order Summary in the Fiscal Impacts section of this report. <br />Concurrent with this project, the San Leandro Boys and Girls Club (Club) is also performing a <br />renovation of its facility. The renovation work includes locker rooms that are used by both Club <br />and pool patrons. The Recreation and Human Services department requested that <br />improvements to the flooring in these rooms be added to the project to improve safety when wet <br />by pool users. <br />Analysis <br />The Boys and Girls Club Pool is an existing facility with a number of hidden conditions that were <br />not able to be identified in the design phase of this project. As mentioned above, several items <br />had reached the end of their useful lives and needed to be replaced. The costs for these items <br />and corresponding extra work identified to date represent almost 17% of the original contract. <br />Authorizing an increase in the change order cap from 15% ($136,843) to 21% ($192,711), an <br />Page 2 City of San Leandro Printed on 1/14/2021 <br />117
