1 City of Santa Ana On -Call Engineering Services (RFP No. 23-030) Throughout the design process, we will monitor project progress, maintain project files, and control the quality of the work performed either by us or our sub -consultants. We have consistently produced a professional -level quality of work product, and we will continue to do so for the City. This is our approach for a standard Design -Bid -Build project that we feel would be typical of the type of projects undertaken by this contract. We have also worked on Design -Build projects and Progressive Design -Build projects. These two approaches could be considered for projects and CWE could assist the City with the project management aspect of these approaches. Areas of Service Civil Design CWE, along with our teaming partners, can provide almost any type of civil design service for the City. Typical approaches for specific areas of service including water, sewer, storm drain, street, sidewalk, bike path, and sustainable infrastructure design are included in the subsections below. Water and Sewer Infrastructure Design and Rehabilitation Water and sewer design and rehabilitation projects will include all connections and appurtenances (restraints, stub outs, fire hydrants, air relief valves, isolation valves, services, etc.) as required to make the connection at the selected points. Designs may include both open -cut and horizontal directional drilling for service laterals on side streets. Construction drawings will indicate existing easement areas, check valves, shut-off valves, directional drilling launch pit locations, air release valves, vaults, and stub out for future use as directed by the City. Directional drilling will be for private service connections and should only require permission from the resident to finalize the household connection. We have assumed all coordination with the residents will be performed by City staff. Water and sewer design and rehabilitation may also include evaluations, studies, and recommendations related to water wells, reservoirs, water treatment systems, disinfection systems, pressure control systems, and sewage lift stations. These studies may take the form of a water and sanitary sewer system master plan, or other similar planning document. A Water and Sanitary Sewer System Master Plan provides the City with a tool for planning water and sanitary sewer collection system infrastructure improvements. The primary purpose of the Master Plans is to evaluate the capacity of the City's existing infrastructure under current conditions and plan for the capacity required by future conditions associated with anticipated development projects. To analyze the impacts of existing and future water and sewer flows, a numerical hydraulic model needs to be developed. To fully assess existing conditions and plan for the future capacity needs of the system, future flow estimates should incorporate the changes in demand and flows that would be generated by anticipated development and the additional water that enters the sewer system from storm -related events, and losses from the aging water infrastructure. This would require hydraulic modeling of the water distribution and sewer collection systems, which CWE has the capability and experience to perform. 15 GE
