HomeMy WebLinkAboutItem 12 Approval of Amendment No. 1 for CPH to Provide Design Services for the Ocoee Wastewater Plant Electrical UpgradeMeeting Date: September 19, 2023 Item #: 12 Contact Name: Trent Hopper Department Director: Jamie Croteau Contact Number: Ext. 4306 City Manager: Robert Frank Subject: Approval of Amendment No. 1 for CPH to Provide Design Services for the Ocoee Wastewater Plant Electrical Upgrade. (Utilities Director Croteau) Background Summary: This Ocoee Wastewater Treatment Plant Electrical Upgrade consists of design, construction, and an upgrade to the Wastewater Treatment Plant's existing power supply system. The existing power supply has been in place since 1999, and its electrical capacity has reached its limit. On March 1, 2022, the City Commission approved a proposal from CPH to provide the design services associated with this project at a cost of $246,902.00. In an effort to maximize the long-term benefits this project will provide, Staff explored options that were not included in the initial design scope and determined that relocating the blowers would allow for the use of higher -efficiency blowers. The Electrical Engineer for this project has estimated the use of higher efficiency blowers will provide a cost benefit of $3,594.00 per month. CPH has provided an amendment to the original proposal in order to expand the design scope to include the blower relocation for an additional cost of $27,566.00. Issue: Should the Honorable Mayor and City Commissioners approve the additional funding of $27,566.00 for the design services for the Ocoee Wastewater Plant Electrical Upgrade from CPH? Recommendations: Staff recommends that the Honorable Mayor and City Commissioners approve Amendment No. 1 from CPH to provide the design services required for the Ocoee Wastewater Plant Electrical Upgrade and increase the budget for this project in the amount of $27,566.00. Staff also recommends that the City Manager be authorized to approve change orders to this contract up to the limit of his purchasing authority for each change order, and up to the budgeted project amount for this project for all change orders. Attachments: 1. Ocoee WRF Electical Improvements Amendment 1 (15-Aug-2023) Financial Impacts: None as this project is adequately funded.

(PSI), an Intertek Company, is pleased to submit the following proposal for performance of a subsurface exploration at the site of the proposed improvements. The subsurface exploration will be completed to provide geotechnical recommendations for site preparation and foundation design for the new electrical building and generator pads. Presented herein is the proposed scope of work, time schedule to complete the work and cost estimate for our services. This proposal is based on the boring locations being readily accessible to our truck -mounted drilling equipment and the drilling services being performed during regular business hours. Protect Information The project site is located within the Ocoee Wastewater Treatment Plant (WWTP) in Ocoee, Orange County, Florida. The site is bordered by an existing building and pavement areas to the north and wastewater treatment systems to the east, south and west. Based on a review of aerial images available through Google Earth Pro, the site is vacant with the ground cover comprising grass. Planned improvements for this facility include two new generator pads plus a one-story electrical building. The generator pads will each have an approximate plan area of 130± square feet. The electrical building will have a plan area of approximately 430± square feet. We assume the generator pads will be designed as slab on grade systems. For the one-story building we expect it to be relatively light with maximum column and wall foundation loads of less than 50 kips and 3 to 5 kips per linear feet, respectively. The listed assumptions have been used for the purpose of preparing this proposal. Adjustments to the scope of services may be necessary if the planned development differs from the noted assumptions. Engineering Certificate of Authorization 3684 www.intertek.com/building Ln) 174 of 193 0 Scope of Geotechnical Services Proposal Number: 0757-357521 CPH, Inc. October 26, 2021 Page 2 of 3 The purpose of PSI's subsurface exploration is to obtain information on the general subsurface soil and groundwater conditions within the proposed development in order to provide geotechnical recommendations for site preparation and foundation design. The following services will be provided in order to achieve the preceding objectives: 1. Review available published geologic and topographic information. This published information will be obtained from the appropriate quadrangle map published by the United States Geological Survey (USGS) and the "Soil Survey of Orange County, Florida" published by the United States Department of Agriculture (USDA) Soil Conservation Service (SCS). 2. PSI will perform three (3) Standard Penetration Test (SPT) borings in the areas requested. It is proposed that the generator pad borings will be extended to depths of 10 feet below existing grade, with the building boring will be extended to a depth of 15 feet below existing grade. 3. Visually classify and stratify representative soil samples in the laboratory using the Unified Soil Classification System. Conduct a limited laboratory testing program, if necessary. Identify soil conditions at each boring location and form an opinion of the site soil stratigraphy. 4. Collect groundwater level measurements in the boreholes and estimate the normal seasonal high groundwater levels. 5. The results of the field exploration and laboratory tests will be used in the engineering analysis and in the formulation of PSI's geotechnical recommendations. The results of the subsurface exploration, including the geotechnical recommendations to support the construction of the proposed electrical building and generator pads, will be presented in a written report supervised by a Professional Engineer licensed in the State of Florida. The report will include the estimated normal seasonal high groundwater levels, site preparation, foundation design, excavation considerations and the data on which they are based Schedule We are in a position to start work on the assignment immediately upon receipt of authorization to proceed. The first tasks will be to coordinate obtaining utility clearances for the borings through Sunshine State One Call of Florida and through the plant operations personnel. If private utilities are not located by others, we can coordinate a private utility location service for our borings for an additional fee. Once utilities have been cleared/located, we anticipate one day to complete the field work. Engineering and laboratory testing will be initiated thereafter, requiring a further 10 workdays to complete. From notice to proceed through submittal of the report will require on the order of 4 weeks. Throughout the course of our work on the project, we will keep you routinely apprised of findings plus be available for consultation and meeting attendance as may be necessary. untertek www.intertek.com/building Page 175 of 193 0 Service Fee Proposal Number: 0757-357521 CPH, Inc.
