CITY OF LODI
COUNCIL COMMUNICATION
AGENDA TITLE: Adopt Resolution Authorizing City Managerto Execute a Contract Change
Order with Western Water Constructors, Inc., of Santa Rosa, for Work Related
to Concrete Lining of Sludge Lagoon No. 1 and Associated Equipment at the
White Slough Water Pollution Control Facility and Appropriating $900,000
MEETING DATE: July 16,2008
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt a resolution authorizing the City Manager to execute a
contract change order with Western Water Constructors, Inc., of
Santa Rosa, for work related to concrete lining of Sludge Lagoon
No. 1 and associated equipment at the White Slough Water
Pollution Control Facility and appropriating $900,000,
BACKGROUND INFORMATION: The White Slough facility currently has one operational sludge
lagoon (Sludge Lagoon No. 2) and one vacant sludge lagoon
(Sludge Lagoon No. 1). Due to changes in the discharge permit, the
City is required to increase the sludge -holding capacity. The most
expeditious and economical method to increase sludge -holding capacity and meet the requirement is to
concrete line Sludge Lagoon No. 1 and place it back in service, as shown on the attached drawing.
Staff proposes to use Western Water Constructors, Inc., to perform the work included in this change
order because they are currently under contract for the Phase 3 improvements project. Western Water
Constructors has crews and equipment available to begin the work immediately so that the lagoon can be
completed and placed in service before the next rain season. Final change order pricing is being
negotiated. The Engineer's estimate for the work is $1,032,000. Working together on value engineering
ideas, City staff and Western Water Constructors believe the work can be completed for less then
$900.000. The contract change order for this work would be approximately 5.5% of the original contract
price. The requested appropriation includes contingency funds in case unknown conditions are
discovered during the actual installation. The change order costs have been reviewed by City staff and
our design engineers, West Yost & Associates.
FISCAL IMPACT: This work was anticipated in the cost estimates for the multi -phased
White Slough Water Pollution Control Facility Improvements.
FUNDING AVAILABLE: The requested appropriation of $900,000 will be from 2007 Certificates of
Parti ' i roceeds.
