SUBJECT: IRVINE TERRACE LANDSCAPE IMPROVEMENTS — PERMISSION TO
INCREASE CONTINGENCY AMOUNT TO ACCOMMODATE
UNFORESEEN EXTRA WORK - CONTRACT NO. 3865
RECOMMENDATIONS:
Authorize a total not -to- exceed contingency amount of $37,018 (42% of the total bid
amount).
DISCUSSION:
The City Council, at its April 14, 2009 regular meeting, awarded the Irvine Terrace
Landscape Improvements Project to Tal Cal Engineering for the $88,982 low bid and a
$8,900 (10 %) construction contingency for a total award amount of $97,882.
During construction and excavation of the parkway, it was discovered that the existing
parkway and asphalt concrete travel path was constructed on top of an old roadway.
Ground covers were then installed above the buried asphalt concrete pavement.
The extra work to dispose of the buried pavement between Jamboree Road and Irvine
Terrace and the additional irrigation system components required to make the design
shown on the plans functional have depleted the 25% contingency amount approved by
the City Manager in accordance with Council Policy F -3. Additional removals still need
to take place between Irvine Terrace and Avocado Avenue in order to install the new
parkway improvements at depths below the buried pavement and concrete layer.
Since the work site has been exposed, staff does not anticipate other changed field
conditions. The total contingency amount needed to complete the project is
approximately $37,018 or 42 %. While a 10% contingency allotment would be sufficient
for most projects, the cost of non- competitive change orders can escalate and quickly
surpass the minimal 10% contingency allotment on a small project. The percentage
change on small project change orders then appears excessive.
The approximated total cost of this project including all change orders is $126,000. The
next responsive total base bid amount received on this project was $149,008.67.
