Stevens Water Treatment Plant Sedimentation Basin Improvements and Pre-Sedimentation Basin Dredging CITY PROJECT NO. 18130A PROJECT DESCRIPTION The City of Corpus Christi (City) owns and operates the 161.5 MGD O.N. Stevens Water Treatment Plant (ONSWTP) that currently uses a Trac-Vac solids collector system in their two primary sedimentation basins in Plant 1. The existing Trac-Vac system requires constant maintenance from plant staff and experiences frequent failures due to lost suction or problems with the solids blanket. The City considers the system obsolete and believes it has outlived its useful design life. Due to the inefficiencies and ineffectiveness of the existing solids collector system,the City plans to upgrade the system and has requested a detailed condition assessment, design, and construction services for the solids collector system replacement. Furthermore, the pre-sedimentation basin at ONSWTP is used to store solids from the incoming raw water. Recent surveys have indicated that the pre-sedimentation basin requires dredging to restore the available volume for storage. The first part of this project includes preparation of a construction package for dredging of the pre- sedimentation basin. Under the small contract it was estimated that the pre-sedimentation basin is over 55% full. Dredging of Lagoons 5 and 6 is being performed under a separate task authorization. Separate construction packages will be prepared for the pre-sedimentation dredging work and the solids collection system replacement. This allows the dredging portion to be expedited as well as allowing selection of qualified contractors for the respective work. The second part of this project is to design a new solids collector system to replace the existing Trac-Vac system. Additionally, the clarifier drive mechanisms on the circular scrapers at Plant 2 will be replaced. It is expected that increases in plant capacity will be achieved using plate settlers, tube settlers, or another equivalent technology. Therefore, considerations will be made to provide sufficient clearance for the high rate settling equipment. The ENGINEER will be responsible for the following: • Sedimentation Basin Structural Repairs • Site Preparation • New Solids Collector System Detailed Design City Proj. No. 18130A Exhibit"A" Page 1 of 28 • Conduct a site visit with ONSWTP staff to another facility using the proposed solids collection technology • Demolition of the existing Trac-Vac System • Replacement of the circular clarifier drive mechanisms at Plant 2 • Instrumentation and controls for integration of the solids collector system with plant control system • Preparing construction package for the pre-sedimentation lagoon dredging • Development of Opinion of Probably Construction Cost (OPCC) • Preparation of Contract Documents • Assisting the City in advertising and bidding the project • Services during construction including review of submittals, RFIs, and change order requests and attending regular construction progress meetings • Assistance during startup and commissioning SCOPE OF SERVICES PART A— PRE-SEDIMENTATION BASIN DREDGING The first part of this project includes preparation of a construction package for dredging, dewatering and disposal of residuals from the Pre-sedimentation basin. As mentioned in the project description, there is an immediate need to dredge the Pre-sedimentation basin for operational flexibility and to address water quality issues while long-term solids handling facilities are planned under the next phase of City Project No. 180195 (O.N. Stevens Water Treatment Plant Solids Handling and Disposal Facilities). The ENGINEER will be responsible for the following: • Dredging Plans and Specifications • Preparation of Contract Documents • Assisting the City in bidding the project • Services during construction including review of submittals, RFIs, reviewing test data, tracking landfill quantities, and change order requests and attending regular construction progress meetings 1.

This level would be used to generate a topographic surface to quantify the solids. The survey described here is for post-construction "as-built" conditions to verify quantity removed and resulting residual levels. The pre-construction "existing conditions" survey to verify existing conditions and provide accurate information to Bidders is not included in this scope. The residuals survey generally consists of the following tasks: • Establish control using existing on-site control points • Survey existing water surface elevation (WSE) in pre-sedimentation basin • Perform boat based residual survey o Probe below water surface several feet into existing residuals blanket with Sludge Judge® to obtain sludge sample. The sample obtained is similar to a typical undisturbed core sample obtained by a Shelby tube or split spoon sampler common in geotechnical engineering. o Record total depth below water surface of Sludge Judge® insertion o Record horizontal (X and Y) coordinates of location of residuals sample and unique data point identification (ID). o Retract Sludge Judge® and measure and record total depth of residuals column in sample collected. o Release sample(unless sample retention is needed for analysis) and rinse Sludge Judge®. o Move boat to next sample location and repeat the process for each sample and survey point. • Top of residual elevation (Z coordinate)is then calculated as WSE—Total insertion depth + Depth of residual column in sample. • The top of residual elevation is then added to each unique data point ID in CADD software to develop a top of residual surface for the entire lagoon or pre- sedimentation basin. Deliverables: • Final residual exhibits showing plan and section views of post construction (as-built) conditions. City Proj. No. 18130A Exhibit"A" Page 12 of 28 4.08 Residual Quantities Tracking and Verification This task will help in tracking the project progress and residual removal rates. The ENGINEER will provide the following services. • Track program progress, expenditures and available program funds by compiling Contractor pay requests and residual removal quantities from contractor daily logs and will provide the data to the City monthly. • Track and tabulate daily percent solids testing and landfill tickets to calculate total Contractor production. • Review percent solids lab test results for consistency and accuracy. Coordinate with City, Contractor and third party lab in case of discrepancies to remedy the discrepancy. • Provide regular updates to the City on funds allocated and funds remaining. • Coordinate with City staff on any required changes throughout the duration of the project as directed by the City. • Track Contractor compliance with stated, project specific, project milestones. • This scope of work assumes that there will be no option for Contract Renewal to substantially increase total contract DT quantity. • The Pay Request verification services described above and included in this amendment are based on one contract term for removal of approximately 33,500 DT of solids and of a duration not to exceed 15 months. This scope of work is dependent on receiving weekly scale reports from Cefe Valenzuela staff. This scope of work is also dependent on Contractor providing weekly composite percent solids lab results and daily logs. The Contractor daily logs should include dredging progress, quantities and characteristics of residuals dredged and dewatered, moisture content of the solids (dredged and after dewatering), residuals level, average residual removal rate, and dewatering rates.
