e CITY OF CORPUS CHRISTI CONTRACT FOR PROFESSIONAL SERVICES The City of Corpus Christi, a Texas home rule municipal corporation, P.O. Box 9277, Corpus Christi, Nueces County, Texas 78469-9277 (City)acting through its duly authorized City Manager or Designee (Director of Engineering Services) and LNV. Inc., a Texas corporation, 801 Navigation, Suite 300, Corpus Christi, Nueces County, Texas 78408, (Arch itectlEngineer—A/E), hereby agree as follows: 1. SCOPE OF PROJECT Oso Water Reclamation Plant Nutrient Removal and Re-rate to 24 MGD-Phase 2 Final Pro'ect No. El 2206) -The Oso Water Reclamation Plant (WRP) is the largest of the six treatment plants in the City of Corpus Christi and is located at the corner of Ennis Joslin Road and Nile Drive, adjacent to the Texas A&M University-Corpus Christi Athletic Facility. The plant currently serves the large and growing service area on the City's south side which consists of approximately 24,143 acres and over 50% of the City's population. The Oso WRP is currently operating under a 20 milligrams per Liter (mg/L) BOD5(5-day biochemical oxygen demand) and 20 mg/L Total Suspended Solids permit and discharges into Oso Bay (Cayo del Oso) which is on the United States Environmental Protection Agency's list of impaired water bodies. The plant is operated with a current allocation of 16 staff members and produces an effluent quality that is in compliance with the Texas Commission on Environmental Quality's (TCEQ) Type II Reclaimed Water (§210.32) regulations. The Oso WRP was originally constructed in 1941 and several expansion projects have occurred over the years. The most recent major upgrade to the Oso WRP was completed in 1982. The project consisted of converting the plant's activated sludge process to a contact stabilization process and upgrading the plant's treatment capacity to accommodate average daily flows (ADF)of 16.2 million gallons per day(MGD)and peak two-hour flows up to 98.0 MGD. The Oso WRP is currently configured as two parallel treatment trains; each rated at 8.1 MGD average daily flow. The Oso WRP currently treats about 11.3 MGD which represents approximately 70% of the plant's ADF design capacity and based on growth projections,this is expected to increase to approximately 15.2 MGD once the service area is completely developed. Per TCEQ regulations, design for increased capacity must be underway when flows to the plant reach 75% of design capacity. As mentioned above, the TCEQ has recently adopted more stringent restrictions on ammonia levels intended to protect sea grasses in the bay systems. On April 29, 2011, the TCEQ issued a renewal of the plant's Texas Pollutant Discharge Elimination System (TPDES) permit which included new effluent ammonia limits on 30-day average, 7-day average and daily maximum of 4 mg/L, 6mg/L and 10mg/L, respectively, along with a milestone compliance date on or before October 29, 2013. Prior to this renewal, the Oso WRP permit had not contained an ammonia limitation. The purpose of the compliance schedule was to provide sufficient time for the City to design, construct and commission the necessary improvements to meet this ammonia limit in the near-term. The existing contact stabilization configuration of the Oso WRP was designed to remove BOD efficiently, but is 2013-191 Ionia removal nor is it allowed by TCEQ to be used as a nitrifying 6/11113 Contract for Engineering(AIE)Serviobs M2013-102 Page 1 of 5 1WASTEWATER\E12206 OSO WRP NUTRIENT REMOVAL&RE-RATE TO 24 MGD-PH 2(FINAL)ICONTRACTICONTRACT.DOC LNV Inc. INDEXES] 1 process to remove ammonia. As a result, major facility upgrades at the Oso WRP are necessary to comply with this new ammonia limit. It should also be noted there are indications from the regulators that Total Nitrogen (TN) and Total Phosphorus (TP) limits are likely to be imposed upon the Oso WRP within the next several permit renewal cycles. To attain compliance by October 29, 2013, the City adopted a strategy of implementing near-term (Phase 1)and long-term (Phase 2) improvements at the Oso WRP. This strategy allows the City to implement cost effective improvements as a temporary means of meeting the new effluent ammonia requirements in the near-term while planning, designing, and implementing the permanent long-term Phase 2 facility improvements following completion of other on-going major capital projects such as the New Broadway Wastewater Treatment Plant. Phase 1 improvements included the temporary Breakpoint Chlorination Facility(BPC) and Step Feed modifications which are currently under construction and are scheduled for completion in September 2013. Phase 1 will achieve compliance with the ammonia limitations in the City's discharge permit within the mandated timeframe. However, as a result of the increased operating and maintenance costs and added complexity to the operation of the plant, these improvements will not meet the cost/benefit requirements of a long-term solution. The proposed Phase 2 scope of service has been broken into two contracts referred to as Contract A and Contract B. Contract A includes the Phase 2 facility upgrades necessary for the plant to meet additional anticipated regulatory requirements, provide additional treatment capacity to meet projected increased plant flows, to ensure continued plant reliability, and to replace the temporary Phase 1 improvements. Technical Memorandum No. 6-Regulatory Compliance and Implementation Plan describes the major capital improvements necessary to meet the current and anticipated (future) effluent regulations. Contract B includes the decommissioning of the Laguna Madre Wastewater Treatment Plant (WWTP) and a transfer pump station. Technical Memorandum No. 9-Oso WRP Phase 2 Cost/Benefit Evaluation provides the background information on the drivers of the Oso WRP Nutrient Removal project, presents the results of a cost/benefit evaluation, and describes additional recommended improvements associated with the decommissioning and flow transfer from the Laguna Madre WWTP. This Phase 2 scope of service is intended to implement the improvements recommended in TM-6 and TM-9. At this time, this contract is based on the traditional project delivery method of design-bid- build for both Contracts A& B. However, City staff is currently investigating the feasibility, benefits and weaknesses of an alternative delivery method referred to as Construction Manager at Risk (CMAR). The preferred delivery method will need to be selected by the City prior to beginning the design phase(approximately 30%design level) and this contract will need to be modified appropriately if any alternative delivery methods are chosen.

Project No. E12206 GENERAL INFORMATION The Oso Water Reclamation Plant(Oso WRP) serves a large and growing portion of the City of Corpus Christi, Texas(City). Significant facility upgrades are necessary for the plant to meet anticipated regulatory requirements, future plant flows,to ensure continued plant reliability,and to replace the temporary Phase 1 Breakpoint Chlorination(BPC)Facility. The BPC Facility is currently being constructed as a temporary means of meeting the plant's new effluent ammonia requirements in the short-term while planning, designing and implementing the permanent long-term Phase 2 improvements. Technical Memorandum No. 6—Regulatory Compliance and Implementation Plan completed in Phase 1 describes the major capital improvements necessary to meet the current and anticipated(future) effluent regulations. In addition,Technical Memorandum No. 9—Oso WRP Phase 2 Cost/Benefit Evaluation provides the background information on the drivers of the Oso WRP Nutrient Removal project,presents the results of a cost/benefit evaluation, and describes additional recommended improvements associated with the decommissioning and flow transfer from the Laguna Madre WWTP. This Phase 2 scope of service is intended to implement the improvements recommended in TM-6 and TM-9. The LNV Team consisting of Jacobs,Colwell&Associates, and Alan Plummer Associates(LNV or Engineer),has been retained by the City to provide engineering services for the Oso WRP Nutrient Removal Project(Ammonia). On April 29,2011,the Texas Commission of Environmental Quality (TCEQ) issued a renewal of the plant's Texas Pollutant Discharge Elimination System(TPDES)permit which included a new monthly effluent ammonia limit of 4 mg/L. Prior to this renewal,the Oso WRP permit did not contain an ammonia limitation. The renewed permit also included a compliance date of October 29, 2013 to meet the new ammonia limit. The purpose of the compliance schedule was to provide sufficient time for the City to design, construct, and commission the necessary improvements to meet this ammonia limit. Phase 1 of this project includes the temporary Breakpoint Chlorination Facility which is currently under construction and is scheduled for completion in August 2013. The near-term(temporary) solutions are described in more detail in Technical Memorandum No. 3— Ammonia Removal Alternatives Evaluation dated January 3, 2012.

The most recent major upgrade to the Oso WRP was completed in 1982 when the plant's activated sludge process was converted to contact stabilization and designed to accommodate average daily flows of 16.2 MGD and peak hour flows of up to 98.0 MGD. Oso WRP produces an effluent quality that is in compliance with TCEQ's Type H Reclaimed Water(§210.32)regulations. The Oso WRP is configured as two parallel trains;each rated at 8.1 MGD average daily flow. The contact stabilization configuration is designed to remove BOD efficiently,but is not well-suited for ammonia removal and is actually not allowed by TCEQ to be used as a nitrifying process. As a result,the long-term improvements will require major facility upgrades. Based on workshops the team conducted with the City,the Oso WRP upgrades must achieve the following goals and objectives: • Maintain regulatory compliance • Provide biological ammonia and total nitrogen removal • Provide accommodations for implementing future phosphorus removal • Provide Coliform and Enterococci removal and/or inactivation • Re-rate the average daily flow capacity to meet anticipated future flows • Maintain peak hour flow capacity of 98 MGD • Improve process automation and monitoring • Reduce process and maintenance costs • Reduce process odors • Provide operational and maintenance flexibility U:kCorpus Chnsty130190 Oso WRP Nutrient Remove-Rerate 24MGD PH2\AE Cortract�2013-05-07 Oso PH2-EXHIBIT A-1.doa Phase 2 Improvements page 2 Exhibit A-1 May 7,2013 1 r City 4f City of Corpus Christi, TX `NV Oso Water Reclamation Plant Nutrient Removal and Re-rate to 24 MGD- Phase 2 FINAL J�COBS� Ch�'1SCi Project No. E12206 Phase 2 Improvements The Phase 2 improvements to meet the goals and objectives described above are described in detail in TM-6 and will consist of the following elements as shown in Appendix A: • Site Development&Yard Piping—additional cut/fill as needed for the final plant layout,paving, grading, and access roadways, and drainage improvements. Includes site landscaping, on-site miscellaneous yard piping, interconnecting process piping,tie-ins to existing and proposed treatment facilities and coordination with Oso WRP's existing hydraulic profile • New Influent Pump Station—80 MGD capacity, depending upon the results of the evaluation to either eliminate Lift Station No. I or consolidate Lift Stations No. 1 and No.2 into a single submersible style station with dual wet wells;the influent pump station will include a building, flow measurement,pump hoisting system,and automated controls. • New Headworks—mechanical bar screens with associated washers/compactors for the screenings,vortex grit removal with grit pumps and classifiers, and flow splitting. • New Odor Control System—odor control system to serve both the new influent pump station and headworks • New Process Train No. 3 Aeration Basin—approximately 3 MG volume, anoxic and oxic zones, provisions to biologically remove phosphorus in the future,anoxic zone submersible mixers, fine bubble diffused aeration system, internal basin mixed liquor return(N MR)pumps and piping, return activated sludge piping,upgrades to the process air system(blowers&piping), and flow splitter structure • New Process Train No.4 Aeration Basin—approximately 3 MG volume, anoxic and oxic zones, provisions to biologically remove phosphorus in the future, anoxic zone submersible mixers, fine bubble diffused aeration system,MLR pumps and piping,return activated sludge piping, upgrades to the process air system(blowers&piping),and flow splitter structure U:\Corpus Christi\130190 Oso WRY Nutrient Remove-Rerate 24MGD PH2\AE Cantmcr\2013-05-07 Om PH2-EXHIBIT A-l.doo Phase 2 Improvements Page 3 Exhibit A-1 May 7,2013 City of City of Corpus Christi, TX L%kv MFM 115 Oso- Water Reclamation Plant Nutrient Removal and���O� � ��lt'1St1 Re-rate to 24 MGD - Phase 2 FINAL Project No. E12206 • Reconfigure Existing Process Train No. 1 &No.2 (East and West)Aeration Basins—install new baffle walls to create anoxic zones, submersible mixers, fine bubble diffused aeration, diffused air piping,upgrades to the process air system,mixed liquor return(MLR)pumps and piping, walkways/catwalks, and return activated sludge piping • Upgrade Disinfection System—new chlorine solution pumping system, baffles,mixing,chlorine contact chamber mechanical internals • Electrical System Upgrades—overall site electrical for new process facilities, instrumentation and controls,two new electrical control rooms(SCRs), four(4)new standby electrical generators,relocation of two (2) existing generators, and area lighting • SCADA System—new plant-wide supervisory control and data acquisition(SCADA) system to monitor and control all new plant processes • Site and Civil Design—new yard piping to connect new process units, paving and grading, and landscape architectural elements • Maintenance Building--new facility with maintenance bays, shop,parts storage, storage, offices, restrooms, and locker rooms • Laguna Madre WWTP(LMWWTP)Decommissioning&Transfer Pump Station.—overall decommissioning and demolition of the entire treatment plant, 17.5 MGD lift station and force main to transfer wastewater flows from the LMWWTP service area to the Oso WRP, and effluent force main to transfer effluent from the Oso WRP back to the LMWWTP effluent line supplying the NASCC.

Scope Limiting Assumptions The following scope limiting assumptions have been defined: • The total scope of the project will be delivered via one single contract(ie.one set of contract documents). • The Preliminary Project Schedule assumes the project will receive Notice to Proceed from the City no later than July 2013. • The City or Contractor will pay all fees associated with permit applications and plan review including City of Corpus Christi Development Services,Nueces County,TCEQ,and other agencies as required. • The starting point for this Design is based upon the major treatment processes and system recommendations in Technical Memorandum No. 6—Regulatory Compliance&Implementation Plan. Upgrades or evaluations to the new existing Administration Building,Belt Press Solids Dewatering Building and/or those facilities identified during the condition assessment as requiring improvements are specifically omitted from the project. • This contract is based on the traditional project delivery method of design-bid-build for both Contracts A&B. However, City staff is currently investigating the feasibility,benefits and weaknesses of an alternative delivery method referred to as Construction Manager at Risk (CMAR). The preferred delivery method will need to be selected by the City prior to beginning the design phase(approximately 30%design level) and this contract will need to be modified appropriately if any alternative delivery methods are chosen.

While these documents are sufficient to guide the operations and maintenance of the equipment and systems at the facility,the City has indicated a desire to compile a comprehensive plant Operations and Maintenance (O&M) manual that would bring together the information required to operate and maintain the overall facility.The major objective is to provide operations and maintenance staff with quick access to the information that is essential to performing their jobs. With today's technology,LNV does not believe that an O&M manual should be a static document that is stored on a shelf,but rather should be an interactive web-based tool providing nearly instantaneous access to the stores of information that should be available to the operators. The LNV approach to developing electronic O&M manuals in the most efficient way is to focus on five fundamental issues: • Making sure the content is correct and current. • Developing good interface aesthetics and graphics to provide a pleasing user experience. • Making the manual usable through attention to proper organization and coherent navigation. • Providing a system that can be easily modified and/or expanded. • Making technology decisions that allow for integration of new technologies,without an excessive technology-maintenance burden on the City. Beyond any other consideration,the content must be correct and focused on what the O&M staff needs to know. The electronic O&M manual format provides the opportunity to keep write-ups on procedures, control descriptions,etc. short and to the point(a fundamental in any web page design as well as in a successful O&M manual). Yet deeper levels of detail can be provided through links in the documents to allow the user to research a problem to its fullest extent, if necessary, for the task at hand. A key to the success of an O&M manual project, in whatever format, is the involvement of the end users. O&M staff at the facility must be provided the opportunity to contribute to the development process in a way that doesn't increase their workload,but does allow meaningful contributions. LNV will work directly with the users in developing and verifying our O&M manual content.

The starting point will be the electronic format for the New Broadway WWTP currently under construction. LNV will then develop a content shell for review by the City prior to installing the content. This task will include coordination with the City's systems integrator, security coordinator, and technical staff as well as the end users. LNV will organize the electronic O&M manual format to address the user's needs in six areas: • Content • Aesthetics • Usability/Features • Information Maintenance/Expansion • Technology/Implementation • Information Security The site will be designed with the following basic layout: • Functional navigation buttons (help, search, feedback) at the very top of the site. • Topical navigation menu on the left side of the screen. An expanding tree menu system will be used to organize content by process area and topic. The look and feel of the site will be managed using cascading style sheets to make it easy to modify aesthetics across the site.The O&M manual will be developed as a web site, suitable for access using a U:\CorPwChristi\130190 Oso WRP Nutrient Remove-Rerate 24MG0 PH2\AE Contmd\2013-05-07 Oso PH2-EXHIBIT A•i.d.

In addition,LNV will assemble the large quantity of reports and drawings gained from City through previous project work on the Master Plan and Preliminary Design. The information to be researched and inventoried will include the following types of documents relating to the Oso WRP: • Original Equipment Manufacturer Manuals • Design Reports • Construction Drawings and Specifications • Permit Applications and Approvals • Materials Safety and Data Sheets • Written Facility and City Policies LNV will compile these documents and coordinate the copying or transfer of the information into the appropriate electronic format. After a review of the design drawings and specifications, manufacturer's manuals, and existing plant data systems(CMMS, etc.),an inventory of the plant equipment will be conducted in which nameplate information will be collected for major pieces of equipment. That information will be entered into the Plant Design Database developed by LNV and used in the Design Phase.

While the traditional design-bid-build delivery method remains the most common method,there is considerable interest on the part of Owners in alternative methods of project delivery and the potential of these alternative methods to save money and time. The decision on the project delivery method for the Phase 2 Improvements impacts various aspects of the project including financing,procurement,ownership,and the associated levels of risk carried by the involved parties. Several fundamental project considerations are directly impacted by the delivery method selected.These considerations include the need to adhere to a realistic budget,a schedule that accurately presents the performance period, a responsive and efficient design process that leads to a quality set of documents, a thorough risk assessment followed by the proper allocation of risk by the owner, and a recognition of the level of expertise within the owner's organization or available to it. The most typical methods can be divided into three basic categories:Design-Bid-Build, Construction Management At Risk(CMAR),and Design-Build. The project delivery methods to be examined are: Design-Bid-Build(DBB)—The traditional project delivery approach,which customarily involves three sequential project phases: design,procurement,and construction. Construction Management At Risk(CMAR)—A project delivery method in which the Construction Manager acts as a consultant to the owner in the development and design phases,but assumes the risk U:\Corpm Christi\130190 Oso WRP NutrfeM Remove-Retake 24MG0 PHAAE Contract\2013-05-07 Oso PH2-EXHIM A-Ldoa Phase 2 Improvements Page 64 Exhibit A-1 May 7,2013 City of City of Corpus Christi, TX LNV =CABS Oso Water Reclamation Plant Nutrient Removal andm Chf'1511 Re-rate to 24 MGD- Phase 2 FINAL Project No. E12206 for construction performance as the equivalent of a general contractor holding all trade subcontracts during the construction phase. Design-Build(DB)—A project delivery method that combines architectural and engineering design services with construction performance under a single contract. The project delivery analysis will evaluate each alternative project delivery model for life-cycle costs, risks,and qualitative 1 quantitative factors and issues.The analysis will include a stakeholder process to receive input from Owner and managers most affected by the new project.This will be accomplished through a series of workshops soliciting stakeholder input. The typical considerations in selecting the most beneficial delivery method are as follows: • Owner's Requirements and Risk Considerations • Project Delivery Methods Available to the Owner • Role of the Construction Manager • Contracting Alternatives • Procurement Alternatives The result of the analysis process will be a recommendation for the most appropriate approach to be used for the Phase 2 Improvements. 14 LMWWTP Decommissioning The Laguna Madre Wastewater Treatment Plant(LMW WTP) serves the entire Flour Bluff peninsula, operates as an activated sludge process and discharges into the Laguna Madre.

Biogas is typically used as the fuel source for a hot water or steam boiler with a heat exchanger to maintain the anaerobic digestion system at the desired temperature;when combined with an internal combustion engine and a generator to simultaneously produce electricity and useful heat,the process is called cogeneration. As the anaerobic digestion process requires primary sludge from the primary clarification,primary clarifiers need to be added to the existing liquid stream process at the Oso WRP. In additional to primary clarifiers,primary sludge pumping and WAS thickening will be needed to augment the anaerobic digesters. The Engineer will prepare a feasibility study to estimate the cost of utilizing biogas in a cogeneration facility to produce electrical power for the Oso WRP and waste heat from the gas engine to heat the digesters. The feasibility study will also evaluate the cost of a natural gas-fuel engine and generator to produce electricity to meet the electrical demand of the expanded Oso WRP as described in TM 6. The feasibility study will include the following: • BioWinTM Process Modeling—The existing BioWinTM model of the Oso VW will be updated to include primary clarification,primary sludge pumping,biological nutrient removal, secondary clarification WAS thickening with filtrate return flow,anaerobic digestion, and dewatered sludge filtrate return flow at the design flow of 24 MGD. The model output will confirm the treatment unit sizing,process air demand, effluent quality, sludge production, and biogas production design criteria. The model will assume the anaerobic digesters will be high-rate with supplemental mixing and heating and operate in the mesophilic range at 35-C to produce Class B biosolids. • Preliminary Site Plan—An Oso VW site plan will be prepared. It will be based upon the proposed site plan in TM 6 with the addition of the new treatment processes described above, new odor control equipment, and a cogeneration facility. • Sequencing Plan—A sequencing plan will be developed for the startup of the new process units of the Phase 2 project,while maintaining the existing plant operations.

Deliverables: Draft and Final Biogas Utilization and Natural Gas Cogeneration Feasibility Study 16 Oso WRP Energy Audit (AUTHORIZED) Providing wastewater service to municipal and industrial facilities requires a significant amount energy. Rising energy costs require wastewater authorities to better manage energy consumption and identify areas for improvement. Wastewater energy consumption generally accounts for 30%to 60%of the total facility's energy bill. Energy represents the largest controllable cost of providing wastewater services to the public.Many facilities were designed and built without energy costs as a major concern. With large pumps, drives, motors, and other equipment operating 24 hours a day,wastewater utilities can account for some of the largest individual energy expenses incurred by a local community.

A wastewater facility energy audit by LNV allows the facility owner to discover ways to save money by improving the energy efficiency of current operations. LNV will examine controls stems,primary and secondary treatments,aeration, and offer recommendations for operational improvements.Typically these may include variable frequency drives for speed control, SCADA control systems,pumping operations, aeration system modifications, and scheduling,building-related inefficiencies,and other upgrades to help your facility use less energy. As part of the energy audit, LNV will provide a comprehensive energy analysis and strategic operating plan offering recommendations for retrofitting,replacement, and energy conservation opportunities. The plan contains a financial payback analysis, including estimated annual savings, estimated cost to implement, simple payback,and a savings-to-investment ratio (SIR)for each recommendation.This allows the owner an opportunity to prioritize energy efficiency measures according to your capital budget and allows you to forecast for future capital expenditures. LNV will provide the City with a strategic commercial energy management plan which prioritizes the most cost-effective recommendations for energy savings.
