SUBJECT: APPROVING AND AUTHORIZING EXECUTION OF CHANGE ORDER NO. 11 TO
CONTRACT FOR TENANT IMPROVEMENTS AT LOS MEDANOS HEALTH CENTER, 2311
LOVERIDGE ROAD,FOR HEALTH SERVICES (WH604B)
SPECIFIC REQUESTS OR RECOMMENDATION(S)&BACKGROUND AND JUSTIFICATION
I. RECOMMENDATION
APPROVE Change Order No. 11 to the Contract dated June 15, 1999 for construction of Tenant Improvements
at Los Medanos Health Center, 2311 Loveridge Road, Pittsburg, with Lem Construction, Inc., Burlingame,
California, and AUTHORIZE the Director of General Services to execute the Change Order, which provides for
the installation of new cast iron soil and vent piping on the first floor. This change order increases the Contract
Price by a total of$360,128.00.
II. FINANCIAL IMPACT
The additional cost of this change order is within the budget recognized by the Board on November 16, 1999.
III. REASONS FOR RECOMMENDATIONS/BACKGROUND
A. After construction began, the contractor discovered that much of the existing cast iron soil and vent piping
system was corroded and leaking, making the system unreliable or unusable. This change order provides for
the installation of a new cast iron soil and vent piping system on the first floor, excluding the kitchen (which
is not being used)and portions of the Clinical Laboratory that do not have damaged pipe.
B. The piping in the kitchen is excluded to reduce cost to this project. There are no current plans for the use of
this part of the first floor.
C. Some of the piping in the Clinical Laboratory is of a different material which has not corroded ("Dur-iron").
This special soil and vent piping serving the Laboratory need not be replaced.
D. The work authorized by this change order is in accordance with the direction given by the Board on
November 16, 1999. Installation,of a new cast iron soil and vent piping system above the first floor will be
accomplished under a separate contract approved by the Board on April 4, 2000.
