The work necessary to complete this contract consisted of distributing notices to affected
residents, traffic control, removing interfering portions and abandoning in place existing
water facilities, furnishing and installing new water mains, water services, fire hydrants,
valves, fittings, waste water lateral and other appurtenances and restoring of all affected
surface improvements, and other incidental items of work to complete the project.
This project was designed on an emergency basis and constructed with an accelerated
schedule due to 3 previous water breaks within the previous 6 months. T.E Roberts
began work two days after council award and completed 20+ days ahead of schedule.
The residents were delighted to see the old water main replaced in such a quick and
efficient manner. This project demonstrated the cooperative work possible between a.
good contractor and city staff from the MOD and Public Works Departments. The new
C -900 PVC line replaces the old ACP main which should prevent further public property
damage from additional water breaks.
Furthermore, the City authorized the current slurry seal contractor American Asphalt
South to slurry the street after all trench work had been completed. This work was
deemed appropriate due to the extensive trenching for the water line as well as the
service laterals that crisscrossed the street. The slurry seal will extend the pavement
life and eliminate the need for an another construction project in the near future thus
minimizing impacts to residents
The contract has now been completed to the satisfaction of the Public Works
Department. A summary of the contract cost is as follows:
Original bid amount:
$249,985.00
Actual cost of bid items constructed:
$252,933.20
Total change orders:
$13,125.00
Final construction contract cost:
$266,058.20
The final construction contract cost is approximately 6 percent above the original bid
amount. The asphalt tonnage was over the estimate due to the additional paving the

contractor performed in this area per City request. Additional paving was required to
permanently repair the damaged pavement in front of the home that had been flooded
twice due to pipe failures. Repair crews had temporarily patched the street knowing this
pipeline job would be coming through at a later date. The native clay subgrade was
found to be unsuitable for use as backfill so a change order in the amount of $13,125
was approved to bring in suitable base material and haul off the native material.
A summary of the project schedule is as follows:
Estimated completion date per July 2010 Schedule: October 21, 2011
Project Awarded for construction: July 12, 2011
Contract Completion Date Plus Approved Extensions: September 15, 2011
Actual Construction Completion Date: August 12, 2011
