URS will provide technical peer reviews of design documents at key project milestones. In addition,URS will provide expert analysis of water treatment process and related facilities as well as technical consultation on an as-needed basis.The deliverables for technical consultations will typically be technical memoranda.Technical consultation will include(but will not be limited to),providing evaluation of alternatives to assist with project and facility planning and prioritization of capital as well as operation and maintenance O&M projects at O.N.Stevens Water Treatment Plant(ONSWTP)and other related water facilities. Specifically,URS will assist with: • Sludge Management Strategic Planning including identification and prioritization ShortTerm,Mid-Term,and Long Term goals and sludge related projects at ONSWTP. To address operational issue at the plant,this task will include detailed evaluation of alternatives for short-term as well as long projects including cost estimating to assist with the selection and implementation of sludge management projects(include sludge generation,handling,collection, and disposal. • Evaluation of alternatives for controlling of algae detected in several basins and lagoons at ONSWTP and preventing future bloom and potential adverse impacts. • Chlorine Safety Improvements Alternatives Evaluations—URS Safety expert will review current operations and procedure and will provide options for improving safety and assess alternatives for future upgrade to the system. • Other technical evaluations as needed to narrow down the number of alternatives to be considered by consultants prior to the final scoping of selected design projects. AMEND. NO. 1 EXHIBIT"A" Page 4 of 10 IntS To avoid costly preliminary design efforts and detailed evaluations of a wide array of options,the Program Management Team will assist City staff with selecting the preferred alternatives(s)based of specific operational needs and technical consideration as well as financial constraints and life-cycle cost considerations (Capital cost as well as O&M Costs).Following the review and approval of the Sludge Management Strategic Plan,the following evaluation will be completed: a. Evaluation of Sludge Handling and Disposal Alternatives The Water Program Management Team will prepare a detailed technical evaluation of long term sludge handling and disposal alternatives including an assessment of the proposed expansion of the pollywog ponds as recently authorized by TCEQ.Disposal to the sewer system will also be evaluated. b. Evaluation of Sludge Collection Alternatives An evaluation of the current Trac-Vac system will also be conducted to identify recommended improvements to the existing system and to evaluate the implementation of alternate sludge collection system(s). c. Evaluation of Alternatives for Control of Sludge Generation This evaluation could be completed concurrently with the evaluation of sludge collection systems and following the evaluation of sludge handling and disposal alternatives. Once the type of sludge handling facility has been identified, factors affecting the generation of sludge will be addressed including coagulant types.The type of coagulant selected may also impact the fmal selection of sludge disposal alternatives. URS will use AGCM(a subconsultant)to assist with the preparation of Costs Estimating: Construction costs as well O&M/Lice Cycle Cost for use when comparing alternatives. B. Wastewater Program Management Services SCOPE OF WORK: URS proposes to provide a wide range of Program Management and technical consulting services related to the Wastewater Capital Improvements Program.These services can be described as functioning as an extension of the City of Corpus Christi staff to enhance alignment and control of project delivery within the Wastewater Capital Improvements Program.This section will discuss the types of services that URS proposes to provide.Work will be provided as directed by the City of Corpus Christi project manager as described in written Work Authorizations.URS will not engage in work without the prior authorization of the City of Corpus Christi.Compensation will be as described under the Agreement. Develop Program Management Plan(PMP):URS proposes to update the Water Program Management Plan to include services related to the wastewater system and reflect the current organizational structure which combined the Water and Wastewater Department. Some key issues to be addressed in the PMP are information flow,decision management and an issue escalation plan in light of the new organizational structure. AMEND. NO. 1 EXHIBIT"A" Pa! : 5of10 URS Program Management: URS will provide management services to help ensure that overarching objectives of the Wastewater Capital Improvements Program are achieved. These services will be provided by an experienced program manager and other support staff on an as-needed basis.The types of activities under general program management include coordination of information flow,schedule tracking,expediting decisions, budget monitoring and providing enhanced programmatic controls. Coordination:URS will conduct project coordination meetings to facilitate communication and collaboration between city departments,design consultants, construction managers,financial consultants, and other program stakeholders.Regular meetings will be scheduled and attended by the URS' PM who shall coordinate information flow between project stakeholders.The URS PM will also be available to conduct or attend executive briefmgs as required. Standardization of Design Contracting: Significant benefits could be realized by implementing standard procedures.Standard procedures can help expedite reviews, avoid duplicated effort and enhance final project outcomes.The PMP will include the development of standardized scopes of work,design procedures,uniform deliverable contents,quality expectations and contract documents. Master Scheduling:URS will maintain a master program schedule to track the progress of individual projects as well as cross-project dependencies. Master scheduling will help keep projects on schedule and improve the coordination between project teams,with outside entities and regulatory agencies. Programming Documents:URS will assist the City to develop strategic programming documents that will be used for high level planning.These documents will assist with project scoping nad formulation,prioritization,sequencing,budgeting. Technical Review:URS will provide technical reviews of design documents at key project milestones.To avoid conflicts of interest,URS will not be called upon to provide actual design services under this contract;however conceptual design may be needed as part of the technical support.We will reach out periodically to subject matter experts within URS to review the work of design consultants and provide comments and suggestions for improving project outcomes. In addition,URS will provide expert analysis of wastewater treatment process design utilizing software such as BioWin, CFD modeling etc. BioWin is a dynamic model to predict wastewater treatment plant performance using plant influent data and plant operating parameters.CFD modeling software is used to identify short circuiting in a basin and identify solutions to reduce/eliminate short circuiting. CFD modeling will be particularly useful for the City of Corpus Christi since some of the City's chlorine contact basins have short circuiting problems. AMEND.NO. 1 EXHIBIT"A" Page 6 of 10 URS Technical Consultation: URS will provide technical consultation on an as-needed basis by recognized subject matter experts.When tasked with providing expert technical consultation,the URS PM will determine the appropriate type of expertise required and screen candidates within URS to identify the best individual for each technical consultation.The deliverables for technical consultations will typically be technical memoranda. Additionally,URS recently met with the wastewater treatment plant operation staff and identified the following deficiencies that need to be addressed in the near future: a. Existing Deficiencies at Greenwood WWTP 1. Unlike all other WWTPs in the City,the Greenwood WWTP uses anaerobic digesters.The existing digester equipment is old, especially the heating system. For consistency with the City's other plants,reducing odor problems,and eliminating air permitting requirements associated with the digester flare gas, the plant operation staff desires to convert the existing anaerobic digesters to aerobic digesters.URS will conduct a technical evaluation including cost comparison between the renovations of the existing anaerobic digester versus conversions of the existing digesters to aerobic digesters. 2. The ultraviolet(UV)disinfection system at the Greenwood WWTP is more than 20 years old.And according to the plant operation staff,it needs improvements since the plant occasionally violates Enterococci limit.The UV system is the primary treatment unit to inactivate/remove Enterococci bacteria. 3. The Greenwood WWTP does not have tertiary filters to remove additional total suspended solids(TSS).According to the plant staff,the addition of tertiary filters will improve the UV system performance and increase plant's ability to meet the TSS limits during unexpected plant's biological process unset. 4. The Greenwood WWTP is not manned during nights when low flow causes excessive DO,resulting in pin flocs formation. The pin flocs can carry over the final clarifiers and may cause permit TSS violations.An automatic control of DOs in the aeration basins is desired by the plant operation staff. Implementation of DO control will require modifications to the existing blowers or installing new blowers.More efficient new blowers are recommended since the existing blowers are more than 20 years,exceeding the normal life. 5. The existing grit chamber equipment is more than 20 years old and it requires replacement according to plant operation staff. Structural catwalks around the aeration basins are failing and they need to be replaced for safety. 6. The plant's existing bubble diffusers need to be replaced by more energy efficient fine bubble diffusers according to plant operation staff. AMEND. NO. 1 EXHIBIT"A" Page 7 of 10 • DRS b. Existing Deficiencies at Whitecap WWTP 1. The existing raw sewage pump station is very old.The pump station needs to be upgraded with submersible pumps per plant operation staff. 2. There is no redundant bar screen at the Whitecap plant.This is a design deficiency that needs to be corrected.Per TCEQ criteria,at least a redundant manual bar screen to be installed.A mechanical bar screen is desired by plant operation staff.The new mechanical screen could be installed in the existing channel that is currently empty. 3. There is no grit removal facility at the plant.The lack of grit facility is causing excessive solid accumulation problems at the splitter box between the aeration basins and final clarifiers as well as excessive wear and tear on all sluice and slide gates.Plant operation staff desires to install a grit processing facility at the plant. 4. The entire electrical system at the plant is corroded and plant operation staff desires to replace some of the severely corroded electrical system. 5. Final Clarifier No. 2 at the plant is a water treatment clarifier which needs to be upgraded to match Final Clarifier No. 1. 6. The supernatant withdrawal system at the digesters needs to be improved per plant operation staff. c. Existing Deficiencies at Laguna Madre WWTP 1. Automatic DO control of the aeration system is desired by plant operation staff. To achieve aeration system DO control,the blowers need to be retrofitted with VFDs and the existing instrumentation and control for the blowers needs to be upgraded. 2. All sluice/slide gates are corroded.Plant operation staff wishes to replace these gates with 304 stainless steel gates. 3. Due to lack of tertiary filters at the plant,sludge accumulation in the chlorine contact basins has been a maintenance problem.The chlorine contact basins are currently cleaned once in every two weeks,and the plan staff plans to clean these basins once in every week in the future.The plant operation staff desires to install tertiary filters to reduce/eliminate sludge accumulation problems at the chlorine contact basins as well as to eliminate the threat of potential TSS permit violation in event of a plant upset. AMEND. NO. 1 EXHIBIT"A" Page 8 of 10 URS d. Existing Deficiencies at Oso WWTP LNV has proposed to expand and upgrade the Oso WWTP. The major elements of the proposed project at the plant included: renovations to the existing lift stations,addition of a headworks facility,upgrade of the existing aeration basins,additions of new aeration basins,electrical and SCADA improvements,and unspecified improvements to the existing chlorine contact basins and digesters. In addition to these improvements, the plant operation staff desires to make additional improvements to the plant.These improvements are: 1. The existing chlorine contact basins are circular,and short circuiting is an issue with these basins. Plant operation staff desires to either make improvements to these basins by installing baffles or construct a new UV facility. 2. There are no tertiary filters at this facility. Adding tertiary filters will add insurance in meeting the TSS limit in case of a plant upset. 3. There are no decant withdrawal mechanisms at the digesters.The plant operation staff desires to add decant withdrawal mechanisms at the digesters and reduce the volume of sludge to the belt presses. 4. The plant operation staff desires to add a parshall flume inside the plant perimeter.The parshall flume will allow the plant operation staff to collect effluent samples from the flume for Enterococci testing.The current effluent samples for Enterococci testing are collected at end of two effluent pipelines, which plant operation staff believes Enterococci bacteria might grow in the pipelines. By adding a parshall flume inside the plant perimeter will eliminate the likelihood of Enterococci bacterial growth before the effluent sample collection point. URS will conduct alternative evaluations and recommend an alternative for each of the deficiencies that the plant operation staff identified.URS will prepare a conceptual- level design on the recommended alternative.However,to avoid conflict of interests, URS will not provide final design services under this contract. Cost Estimating:URS can provide budgetary cost estimates for programming purposes as well providing an independent review of engineer's estimates that are completed by the design consultants. Value Engineering Studies:URS will work with the City's Project Manager to identify individual projects for complete VE studies.At the appropriate design milestone(typically 35%),a URS facilitator will then lead a team of independent professionals through a five-step process following the SAVE International methodology for producing project improvements. Project stakeholders will select the alternatives or recommendations likely to have the greatest potential for project AMEND. NO. 1 EXHIBIT"A" Page 9 of 10 improvements.These alternatives are then incorporated into the program and managed through implementation. In absence of a formal VE study and as part of the design process),URS will make recommendations not only for improving the proposed design, but also for reducing the capital and life-cycle costs of the planned facilities. Procurement Strategy Development:Recent legislation has broadened local governments'ability to utilize alternative project procurement strategies beyond the traditional design,bid-build approach.URS will assist the project stakeholders with the evaluation of available procurement strategies and the recommendation of strategies best suited to individual projects.
