PROJECT UNDERSTANDING WATER RESOURCES (OPTION A) We understand that the City is seeking the design and construction support services for the Santa Ana Water Project. This project includes the rehabilitation of an existing water well approximately 30 years old, and the design of 1500•feet of 12 -inch PVC water main and the construction of 600 -fest of 15 -inch sewer main on an arterial street. The City would like for the consultant to provide feedback regarding the material of choice for the sewer main improvements. Also, the City would tike to connect this well to the water system, as of right now It does connect to an existing onsite reservoir. This well is a sand producer, and currently the capacity has dropped by approximately 35% of its maximum yield of 2000 GPM. The depth of the well Is approximately 11OO-feet, It has a vertical turbine pump with a 250hp motor. in addition, the screens are made of mild steel. No video or any other preventive maintenance has been done in the past 15 years. Well Rehabilitation Our proposed scope of work Is divided into a two-phase approach. Phase I will include reconnaissance of the well to characterize the current condition and develop a rehabilitation plan, Phase it will be to perform the rehabilitation necessary to restore the well to proper working order. Since the rehabilitated well is to be connected to the distribution system, NV5's design will include considerations for the following required appurtenances: • Flow control valve • Pump to waste system • Chlorination • SCADA connection It Is assumed that the well will be re•equipped with a new pump, motor, MCC, and appurtenances, Water and Sewer Mains Both the water main and sewer extensions will be designed according to City standards. NV5 would typically specify high-strength VCP for the proposed 15 -Inch sewer. PROJECT UNDERSTANDING GENERAL ENGINEERING (OPTION B) We understand that the City is seeking the design and construction support services for the Mlle One Street Project, This project will follow a complete street concept. The length of the project is approximately 1,000 linear feet. Both intersections at the outer limits of the project have been modified as part of the complete street project under previous phase. The proposed project consists of street rehabilitation, bicycle lane, sidewalk, and parkway improvements. The sidewalks are 6 feet wide and the Parkways are 4 feet wide. The project also includes widening of the east side of the street to accommodate a new bicycle lane, The right of way is approximately 12 feet wide with three traffic lanes in each direction with a 14 foot wide median. The required right of way has been acquired by the City. GENERAL APPROACH Work Gr .akdown Structure Upon issuance of a notice to proceed, our project manager will meet with team members to review the requirements, prepare a Work Breakdown Structure and make team assignments for maximum efficiency of resources. The detailed WBS will describe all of the work tasks necessary to complete the project. A master project schedule will be prepared following the WBS to show the relationship between tasks, the expected start date and duration for each Item. This schedule will serve as a guide to conducting and monitoring the progress of the work and to ensure projects are completed on time and within budget. To ensure accurate monitoring and tracking of documents, revisions and progress, a document tracking and control system will be developed. We will meet with City project representatives regularly and maintain constant communication to ensure successful and timely delivery of the project. Meeting minutes will be distributed within one week of the meeting identifying actions, items, assignments and due dates. Cost Connol We are able to continually review and evaluate a project's cost through all project phases to enable informed and 25E-441
