SUMMARY
On July 6, 2010 the City Council awarded a contract to E &R Construction, Inc. in the

staffs satisfaction for a total project cost of $264,903.40. This amount reflects the
original contract amount of $246,687 plus contract change orders for additional work,
totaling $18,216.40, or 7.38% of the original contract price.
Staff recommends that the City Council accept all work performed by E &R Construction,
Inc. as complete and authorize the final payment to be made in accordance with the
contract documents, subject to retention of $26,490.34.
DISCUSSION
The eight -inch (8 ") water main along Monte Verde Drive was installed in 1944 and is
made of cast iron, which is brittle and susceptible to leaks and breaks. City crews have
frequently made emergency repairs to this stretch of pipeline. The work also involves
replacement and installation of additional fire hydrants on Monte Verde Drive to meet
current fire protection requirements.
The replacement of the existing eight -inch (8 ") cast iron water main along Highland
Vista Drive north of Highland Oaks Drive was also added to the project due to a recent
major break, which was the second break along this section of mainline in the past
several years. The recent water main break at this location caused roadway damage,
water service disruptions, and excessive repair costs.

The final construction cost of the Project is $264,903.40. This amount reflects the
original contract amount of $246,687 plus contract change orders for additional work,
totaling $18,216.40, or 7.38% of the original contract price. A summary of the additional
work performed in the change order's is as follows:
Change Order Description of Change or Work Amount
Additional work required for asphalt pavement
1 repair on Highland Vista Drive and install additional $4,716.40
main line valves.
Additional work required for the removal and
2 replacement of existing clay soil that was unsuitable $13,500.00
for backfilling the excavation on Monte Verde Drive
Total Change Order $18,216.40
The soil that was excavated on Monte Verde was clay and contained extraordinarily
amount of moisture; thus it was not suitable to backfill with. As a result, the contractor
needed to import crushed aggregate base material which was required to backfill the
water main.
Therefore, all terms and conditions of this contract have been complied with and the
work has been performed to staff's satisfaction. Staff recommends that the City Council
accept all work performed by E &R Construction, Inc. as complete and authorize the final
payment to be made in accordance with the contract documents, subject to retention of
$26,490.34.
ENVIRONMENTAL ANALYSIS:
This project consists of the replacement and minor alteration of an existing utility system
with no expansion of the system and therefore qualifies as a Class 2 categorical
exemption per 15302 (c) of the California Environmental Quality Act.
FISCAL IMPACT:
Funds in the amount of $300,000 have been budgeted as a part of the 2009 -10 Capital
Improvement Program for the Water Main Replacement Project.
RECOMMENDATION:
1. Accept all work performed by E &R Construction, Inc. for the Water Main
Replacement Project as complete.
2. Authorize final payment to be made in accordance with the contract
documents, subject to retention of $26,490.34.
