The added work consists of additional geologist's time, additional
soil tests for the dams, drilling 5 observation wells in the large
dam, monitoring the wells during water draw -down, and performing
stability analysis to insure against failure of the large dam. The
total extra geotechnical work amounts to $36,570.00.
In addition, the extra work on the dam; unexpected coordination
with Walmart contractors who supplied the material for the dam; the
need to calculate new cross sections for the dam before the water
was pumped down to determine the side slopes and quantities; and

Addendum No. 1
September 16, 1993
Mr. Frank Tecca, City Engineer
City of Lake Elsinore
130 S. Main Street
Lake Elsinore, CA 92530
Subject: Additional Geotechnical Services for Temporary Dikes -
San Jacinto River Channel Improvements
Dear Mr. Tecca:
In a status teleconference with Mr. Dick Roberts of Ninyo & Moore, the subject of additional
observations and testing is anticipated and is being performed beyond our original scope of services.
Since the City had entered into an agreement with Ninyo & Moore, we suggested that they forward
incidental services relative to the dikes directly to the City. However, if the City desired RBF to
administer the Ninyo & Moore's contract, I asked Dick Roberts to let me know. Subsequently, Mr.
Roberts called me to express your reques that RBF include the observations, testing and boring
and monitor wells within our Construction Management Services contract.
RBF is forwarding this Addendum to cover Ninyo & Moore's scope of services. The Contract
Addendum amount of $36,570.00 includes 15% for administration, consultation and insurance.
RBF and Ninyo & Moore are available to provide support to any questions you may have for said
services.
Sincerely,
ROBERT BEIN, WILLIAM FROST & ASSOCIATES
