City Council Meeting: February 12, 2002 Santa Monica, California
TO: Mayor and City Council
FROM: City Staff
SUBJECT:Change Order to Contract 7994 (CCS) with KEC Engineering for the Appian
Way Retaining Wall Project
Introduction
This report recommends that the City Council appropriate additional funds and authorize
the City Manager to negotiate and execute a change order to Contract 7994 (CCS) with
KEC Engineering in an amount not to exceed $248,500 plus $30,000 contingency for the
Appian Way Retaining Wall project.
Background
The contract for the replacement of the Appian Way and Moss Avenue retaining walls in
the City?s 1640 beach parking lot was awarded on April 14, 2001 by City Council.
Following contractor mobilization, the south wall supporting Seaside Terrace was found to
have significant damage. A field investigation found that this south wall lacked steel
reinforcement and had no footing, which does not meet current code. Staff is
recommending its replacement with an engineered retaining wall which meets current
code, at a cost of $147,000. In addition, the contractor has encountered unforeseen
concrete debris in the excavation area, which must be removed, at a cost of $26,500; the
California Coastal Commission is requiring landscaping of the Appian Way wall, which will
1
cost $10,000; and, surface restoration of the lot will cost an additional $65,000. This
brings the total change order cost to $248,500.
Discussion
Contract 7994 (CCS), which includes the construction of both the Appian Way retaining
wall and Phase 3 of the adjacent Moss Avenue sewage pumping station, was awarded with
only $50,000 in contingency for the retaining wall. The existing contingency must be
preserved to allow for additional unforeseen field conditions during excavation and small
field changes. Therefore, staff is requesting a change order in an amount not to exceed
$248,500 plus an additional $30,000 in contingency. The restoration of the 1640 beach
parking lot is necessary due to repeated construction stagings of Coastal Interceptor
Sewer (CIS) Moss Avenue Pumping Station projects in the lot, since 1997. The $65,000
cost of restoring the parking lot will be funded by the CIS, and largely reimbursed by the
City of Los Angeles.

FUNDS REQUIRED:
Contract $248,500

Recommendations

1. Authorize the City Manager to negotiate and execute a change order to Contract
7994 (CCS) in an amount not to exceed $248,500 plus $30,000 contingency;
2. Authorize the appropriation of $65,000 from the Wastewater Fund to Account

additional work in conformance with the Administrative Instructions on Change
