Il. Financlallmpact.
This contract amendment allows for an additional $9,004 above the previously
approved contract for$37,500,funded by Federal Emergency Management Agency
Funds:(76%), Road Funds (25%).
Ill. Reasons for Recom mendabLons and Background:
On June 5, 2001; the County executed a Consulting Service Agreement with
Sanders and Associates Geostructural Engineering,Inc. (SAGE)to provide design
and construction related services for repair of erosion along Christie 'Road'
approximately 1.1 mile south of Highway 4. Subsequently, on January 15, 2002,
the Amendment No. 1 was approved to increase the payment limit for additional
design analysis and construction support. In January of 2002, a topographical'
survey was taken of the project area to verify the feasibility of the proposed design
(i.e., a soil nail retaining wall)'. After a review of the survey, the design of the soil
nail wall will, need to be adjusted to accommodate the change in topography. The
additional amount of $9,000 is necessary to incorporate and accommodate the
current conditions in the design plans, The accurate design will allow the County to
limit any change orders that would have been necessary during construction. The
project is scheduled to be advertised for bids on April 2, 2002. Construction i
scheduled to begin in July 2002.
IV. Consequences of Negal�ve'Action:
If the amendment is not approved,the project design may not be sufficient enough
to make the required improvements and would require the County to address the
topography;change during the construction phase at an increased cost.
