FROM: CITY MANAGER DEPARTMENT: UTILITIES
DATE: OCTOBER 5, 2009 CMR: 389:09
REPORT TYPE: CONSENT
SUBJECT: Approval of Amendment No.1 to Contract C08126041 with Siegfried
Engineering, Inc. in the Amount of $70,069 for a Total Not To Exceed
Amount of $614,436 for the Eleanor Pardee Park and Main Libraryl
Community Gardens Emergency Water Supply Wells Project
RECOMMENDATION
Staff recommends that Council:
Approve and authorize the City Manager or his designee to execute the attached Amendment No.
1 to Contract C08126041 (Attachment A) in the amount of $70,069 for consultant's additional
well drilling services on the Eleanor Pardee Park and the Main Library/Community Gardens
Emergency Water Supply Wells Project.
BACKGROUND
The Eleanor Pardee Park and the Main Library/Community Gardens Emergency Water Supply
Wells Project (Wells Project) is part of the overall Emergency Water Supply Project (EWSP),
WS-08002. This project's purpose is to ensure an adequate emergency water supply source is
available to meet the City's emergency water needs.
On March 5, 2007, Council adopted a Park Improvement Ordinance for Eleanor Pardee Park
authorizing construction of a new below-grade well, tree-trimming and removal of one Modesto
Ash in poor condition (CMR: 161 :07). This work will not require permanent closure of the park
to public use and no loss of parkland will occur.
Council's approval in June 2008 (CMR:291:08) of the design-build resolution and the contract
with Siegfried Engineering, Inc. (SEI) authorized City staff to complete preliminary design for
the construction of two new emergency supply water wells to be used during water system
supply shortages.
DISCUSSION
During the pre-design phase, SEI conducted a geotechnical investigation of the two well sites by
drilling two pilot holes for the wells. The original estimate for the depth of the pilot holes for
each site was 450 feet. When this depth was reached it was determined that the estimated well
CMR: 389:09 Page 1 of2
water yields would not meet the required 1000 gallon per minute flow rate. To ensure the wells
could produce at the required yield, the pilot holes were extended an additional 350 feet at each
site. The cost of extending the pilot holes exceeded the original estimates by $70,069.
RESOLIRCE IMPACT'
Funds required for Contract Amendment No. I in the amount of $70,069 are included in the WS-
08002 Emergency Water Supply Project CIP.
POLICY IMPLICATIONS
Approval of Contract Amendment No.1 (Attachment A) does not represent a change to existing
City policies.
ENVIRONMENTAL REVIEW
The field work, including drilling work, conducted during pre-design, as well as the project for
construction of wells in Eleanor Pardee Park and at the Main Library/Community Gardens site,
are part of the overall project EIR for the Emergency Water Supply Project (SCH #2066022038),
which Council certified on March 5, 2007 as being adequate to meet the requirements of the
California Environmental Quality Act (CEQA).
