Mr. Huy A. Ho, P.E. The City of Pleasanton August 13, 2013 Page 3 • The City will perform the California Environmental Quality Act (CEQA) environmental review process. • The City will develop the front-end specifications. • The estimated planning level construction cost of the project is between $2.5 and $3 million. PUMP STATION DESIGN ASSUMPTIONS: • The pump station is a precast structure. • The pump station is not a self-cleaning pump station. • The electrical building will be approximately a 12' x 15' concrete masonry unit (CMU) block building and the electrical building does not include a restroom. • The EARS Pump Station force main will be routed through Johnson Court and along the DSRSD wastewater treatment plant access roadway to discharge in the Pleasanton Junction Structure. • Landscaping is not included in the design. • The scope of work does not include a surge analysis because of the relatively short pipeline distance (approximately 1350 feet) and relatively low velocity. • The EATS pump station discharge pipeline will be rerouted to discharge in the Pleasanton junction structure by installing an additional pipeline from EATS to the Pleasanton Junction Structure. • The pump station will not include a standby generator. In the event of a rower failure, the City will bring a trailer-mounted generator to the site to power the pump station. • The City will contract with another firm to design the process logic contrcller (PLC) and to develop the pump station control strategy. Carollo will design the control schematics and control wiring from each pump etc...to the PLC terminal block, the o:her firm will design the PLC, control strategy, and SCADA controls. • The quality assurance plan (i.e., refer to the general drawings of the S-6 pump station project)will be included in the specifications. • The wet well will be designed with enough room that a macerator system can be added, if needed, in the future. • The pump station site layout will be similar to the layout shown in Figure#7 of the hydraulic modeling technical memorandum. ! t
