Sewer Mains in Various City Streets
Change Orders Nos. 1 & 2
Grgo & Gordon Grbavac Construction
Requests have been received to expand this project to include the
installation of sewer mains in Colorado Avenue (CCO #1) and in
"K" Street, from a point south of Congress Avenue to Rialto
Avenue (CCO #2).
Change Order No. 1 will authorize the installation of an addi-
tional 333 feet of sewer main in Colorado Avenue. An additional
472 feet of sewer main will be authorized in "K" Street by Change
Order No.2. The Contractor has agreed to perform these items of
extra work at the contract unit prices.
The estimated additional costs for Change Orders Nos. 1 and 2
will be $8,995 and $26,985 respectively, for a total increase in
the contract price of $35,980, from $223,759 to $259,739.
A total amount of $475,000 has been allocated from CDBG funds, to
finance the costs incurred for this project. The total estimated
project cost, based upon the actual low bid price, was $281,000.
This estimate included the amount of $36,241 for contingencies,
which could be used to finance the cost of these change orders.
Installation of these additional sections of sewer main
afford the abutting parcels the opportunity to obtain
service. Therefore, we recommend that Change Orders Nos. 1
be approved.
