7. DISCUSSION and BACKGROUND
The City Council awarded the 2016 -17 Annual Water Main Renewal Project at the April 11,
2017 City Council meeting to Big Ben Engineering, Inc. Construction started in June 2017.
The scope of work for the original contract, in general, consists of installation of 16,190 LF of
new water main, services, meters, fire hydrants, valves, fittings, and other appurtenances
complete in place and operational. The project is located in the northern most part of town, just
north of Eisenhower Park, in a high soil corrosion area, where a constant and ongoing
maintenance effort is required. The project was divided into 2 phases for ease of managing and
progress tracking.
Currently, the contractor has successfully completed phase 1 and they are currently installing
pipe for phase 2. The project is on track and will be completed ahead of schedule. With the
strong performance displayed by the contractor and to minimize future disruption for the
residents, staff recommends adding a final phase 3 to the pipeline renewal contract to include
replacement of the remaining pipeline segments identified for replacement, in the same
residential area. Phase 3 will add approximately 4,000 LF of new water main at the same unit
bid price for an additional cost of $758,900.
Staff also requested the contractor replace 180 LF of water main under the Buckeye Channel on
Tustin Street just south of the Meats Avenue intersection. This section of old pipe had several
leaks and could not be repaired. The extra work consisted of labor and equipment needed to
complete the installation of the new water main under the Buckeye Storm Drain Channel. It also
included pavement restoration and traffic control. The lump sum cost for this extra work is
$54,750.68.
The City also incurred a $4,885.56 standby cost during the unforeseen delay of a water main
shutdown during phase 1 construction.
The original contract amount was $3,260,836. Contract Change Order No. 1 in the amount of
$818,536.34 represents a 25.10% increase from the original contract amount, bringing the total
contract amount to $4,079,372.34.
