Transcription

1 Page 1 of 11 Western Municipal Water District Request for Proposals (RFPs) Professional Services for La Sierra Pipeline Project Western Municipal Water District (WMWD) invites the submittal of written proposals from qualified engineering consulting firms interested in providing pipeline, pump stations and chloramination station design services for the La Sierra Pipeline Project in the City and County of Riverside. Interested firms shall submit proposals in PDF format (10 MB file size limit) to Jimmy Chen at jchen@wmwd.com. Proof of on-time submittals will be confirmed with a response from Western. Excluding cover letter, table of contents, resumes, cost and financial data, be limited to 30 single sided, single spaced, and 10 point font size minimum. Submittals shall be addressed as follows: Jimmy Chen, Principal Engineer La Sierra Pipeline Project Engineering Division Western Municipal Water District Meridian Parkway, CA The submittal of the proposal is due no later than 10:00 AM on April 23, The Consultant s Fee Proposal shall be submitted in a separate marked with Fee Proposal clearly on the subject line. There will be a mandatory Pre-proposal Meeting at WMWD Main Conference Room 120 at 10:00 AM on March 25, A job walk will follow Pre-proposal Meeting. The time period to submit questions regarding the request for proposals and/or the project ends at 10:00 AM on April 14, WMWD will issue addenda to the request for proposals if any no later than April 16, Background The La Sierra Pipeline Project will convey potable water from WMWD s Arlington Desalter (AD) to serve the needs of WMWD s Riverside Distribution Service Area. The completion of pipeline and pump stations will reduce the region s dependency on imported water from the Metropolitan Water District of Southern California s Mills Treatment Plant (MTP) and increase water supply reliability. The Final Programmatic EIR (PEIR) for Riverside-Corona Feeder Project (RCF), which La Sierra Pipeline is a component of, was certified in May, Due to pipeline realignment needs, a Final Supplemental EIR/EIS (Exhibit A) that augmented the original PEIR was completed by Albert A. Webb Associates (Webb) in February, Therefore, the scope doesn t include CEQA document. At this time WMWD is not actively pursuing RCF except La Sierra Pipeline Project. 1

2 Page 2 of 11 WMWD retained Webb to do a planning level study of Reaches E/F/G of the RCF Project in Refer to Exhibit A for the alignment of Reaches E/F/G. The result of the study is the La Sierra and Cleveland Pipeline Project Study Report (Report) dated October, 2009 (Exhibit B). The Report outlines alignment alternatives of La Sierra Pipeline and Cleveland Pipeline. Interested consultants are notified that site conditions may have changed after the Report completed in For example the planned high school at the intersection of Pierce and Indiana was built and Indiana in front of the high school was widened. The selected alignment back then may not be the most feasible one now. Kennedy/Jenks Consultants (KJ) was requested to prepare a conceptual planning-level cost estimates for design, construction, and operation for La Sierra Pipeline Project alternatives in KJ presented cost estimates to WMWD in a memorandum dated Jun 15, 2012 (Exhibit C). WMWD requires that the consultant s proposal shall include consideration for complete the plans, specifications, and estimates (PS&E) for both modified Option B (capable of transporting a minimum of 20 cubic feet per second flow (cfs) and Option C on KJ s memorandum. Carollo Engineers completed the Arlington Desalter Expansion Site Master Plan and Preliminary Design Report (PDR) in February, 2010 (Exhibit D). The PDR further identifies final and interim pipeline and facility configurations at AD and future Lake Mathews Water Treatment Plant (WTP) product water clearwell. However, for this RFP Lake Mathews WTP will not be considered. The design at both pump stations shall have provisions to convert from interim to final configurations. Scope of La Sierra Pipeline Project The Pipeline Design Project includes approximately: Modified Option B (KJ s Option B with 20 cfs flow capacity): 24 Diameter Pipeline 25,000 LF 36 Casing for Railroad and Canal Crossings 350 LF 3,500 HP (approx.) Pump Station at AD 1 EA (Station 1) 750 HP (approx.) Pump Station at La Sierra Tank Site 1 EA (Station 2) Option C: 24 Diameter Pipeline 25,000 LF 36 Casing for Railroad and Canal Crossings 350 LF 975 HP Pump Station at AD 1 EA (Station 1) 225 HP Pump Station at La Sierra Tank Site 1 EA (Station 2) Modified Option B aims to provide 20 cfs for one month in case that MTP shuts down. It pumps 3,500 acre feet per year (AFY) baseline flow from WMWD s AD daily. The pumping of baseline flow shall run mostly at night. The design of baseline flow pumping shall consider demand fluctuation between high and low seasons. Assume Low demand is about 60% of high demand. Option C conveys baseline flow only. 2

3 Page 3 of 11 Referring to Exhibit B, there are three (3) reaches in this Pipeline. Reach 1 starts from AD to AD Turnout for a distance of 2,150 feet. Reach 2 is from AD Turnout to La Sierra Turnout for a distance of 11,400 feet. Reach 3 is from La Sierra Turnout to La Sierra Tank and MGL for a distance of 10,200 feet. Interested consultant is made aware that this alignment is not final and is encouraged to study alternative alignment design. On Reach 1 pipeline will cross the Riverside County Flood Control &. Water Conservation District (RCFC&WCD) channel and BNSF railroad in Pierce Street. On Reach 2, there is a RCFC&WCD channel crossing in Indian Avenue. Installing 36 casings at the crossings requires jack and bore construction. Consultant shall design the number of pumps at Station 1 with one as a spare pump for Modified Option B. However, Station 1 has three (3) 350 HP pumps with one as a spare pump per Option C. Total Discharge Head (TDH) is 825 feet for this station. Station 1 needs to convey water from AD to both existing AD-Norco pipeline and La Sierra Pipeline. Due to the high lift, pumps should be designed for efficiency and energy savings. Consultant shall design the number of pumps at Station 2 with one as a spare pump for Modified Option B. Station 2 has three (3) 75 HP pumps with one as a spare pump per Option C. TDH for station 2 is estimated to be 136 feet. To match water quality within the Western Distribution system, a chloramination facility is proposed to treat water as it enters La Sierra Tank and MGL. This chloramination facility will be located within Station 2 site. Station 2 will be located on a WMWD owned property near La Sierra Tank and MGL (Exhibit F). Station 2 discharges water into MGL and La Sierra Tank. Choosing pumps for this station needs to consider pressure variation in MGL. It is suspected that electrical power provided by Riverside Public Utilities (RPU) at Station 1 is not sufficient at peak power demand, therefore; the consultant needs to coordinate with RPU to improve electrical capacity. WMWD operates its facilities through a SCADA system. The new pipeline, pump stations and chloramination facility will need to be integrated into WMWD SCADA system. The capability to power both pump stations with electric power (RPU for Station 1 and SCE for Station 2) and/or natural gas (Shell Oil and Southern California Gas) shall be evaluated and included in the design if feasible. At some of WMWD large pump stations, pumps run on natural gas and use electrical drives as backup to reach maximum energy efficiency. Description of Services Requested The selected consultant shall research as-built drawings and right-of-way documents from various public agencies and private institutions, investigate field topographic, geographic, developments, and street traffic conditions, and prepare PS&E documents for 3

4 Page 4 of 11 public bidding. The consultant will assist WMWD in the bidding process and during the construction. The following are the anticipated scope of services: Task 1.
