CITY HALL 10940 San Pablo Avenue El Cerrito, CA 94530 ScCAP Solar PV Systems Joint Municipal Procurement QUESTIONS AND ANSWERS as of February 15, 2012 and from the Site Visits Q1) I did not see the El Cerrito Public Safety Building in the billing summaries provided. Can you provide it? The El Cerrito Public Safety Building is included in the Excel spreadsheet entitled “SCCAP Demand Accounts energy usage data”. There are a lot of spreadsheets in that file so you will need to toggle through all the spreadsheets to find it. Q2) On the San Pablo City Hall there are four different meters and 3 different rates. Can it be discussed with PG&E to aggregate these meters onto one rate and use one tie in point? No, it appears rewiring the buildings for one tie-in point would be cost prohibitive. Q3) Is it your intention that the contractor provides a Maintenance Bond to cover the 10 year material and workmanship system warranty? The RFP is requesting a 10 Year materials and workmanship system warranty. Is this included in the Maintenance Bond? Please define the terms of the Maintenance Bond. The Maintenance Bond covers work completed as part of a Direct Purchase Agreement. It is to cover the entire project for one year, including workmanship and materials. It is in addition to, and does not take the place of, the minimum 10-year materials and equipment warranties specified in Attachment E, PV System Design Standards. As this minimum10-year warranty is a condition of the CSI Program, it shall be a condition in whatever type of contracting agreement that is negotiated. ---PAGE BREAK--- CITY HALL 10940 San Pablo Avenue El Cerrito, CA 94530 ScCAP Solar PV Systems Joint Municipal Procurement QUESTIONS AND ANSWERS From Site VisitsHeld on February 9 and 10, 2012 El Cerrito Solar Site Visits – Thursday Morning, February 9th, 2012 1.
