CITY O F MOORPARK
TO: The Honorable City Council

DATE: June 28, 1993 (Council Meeting 7-7-93)
SUBJECT: Consider Increasing the Scope of Work to be Provided by

Project
BACKGROUND
On April 21 , 1993 , the City Council approved a contract with Valcon
Engineering to provide the construction surveying services required
for the Tierra Rejada widening project.
DISCUSSION
A. Recap of Existing Contract Scope of Work
Attached as Exhibit 1 is a copy of the current scope of work set
forth in the Valcon Contract. The services set forth in this
exhibit are limited to construction surveying services known to
be required prior to the commencement of construction.
B. Additional Services
The services described in Exhibit 1 are construction surveying
services which were known at the time the contract was awarded
to Valcon Engineering, as being required to support the
construction effort. Since then it has been determined that
certain other services are required of Valcon Engineering, which

are beyond the Scope of Work set forth in Exhibit 1. Those
services are summarized as follows:
Estimated
Item Cost ($)
1. Design Consultation -- Design clarification and modification is required for 4,720
any major construction project. As you know, Valcon Engineering provided design
engineering services to Willdan Associates in the preparation of the project
design. It would be appropriate for the City to retain Valcon to provide these
services directly to the City.
2. Storm Water Pollution Prevention Plan (SWPPP) -- In order to comply with 1,000
certain NPDES requirements, the contract documents require the contractor to
develop a Stormwater Pollution Prevention Plan. That plan must include certain
mapping and hydrology information which must be provided by the City. It is
recommended that Valcon Engineering be retained to prepare this information.
3. Existing Utility Location -- In that the exact future location of the 2,400
utilities to be relocated were not know when the project design was developed,
the design effort did not include the cost of "pot-holing" and locating all of
the existing underground utilities. It is now necessary to perform this work in
order to clarify the scope of certain removal and reconstruction efforts.
Total 8,120
C. Contingency
The above work has been authorized by the City Manager up to a
Not to Exceed figure which is less than the ten percent
contingency ($4,988) previously authorized by the City Council.
This report requests approval of a revised scope of work and fee
to cover the above described work, plus a ten percent
contingency of the revised contract amount.
D. Revised Fee
Adding the services described above , for the fee amounts
indicated, would revise the total fee for services as follows:
Existing Fee $49,880
Additional Services S 8 . 120
Revised Total $58 , 000
Contingency (10%) $ 5 .800
Contract Not to Exceed $63 ,800

from $49,880 to $58,000; and,
