stormwater pump station project.
BACKGROUND INFORMATION: The project was awarded to F & H Construction, of Stockton, in the
amount of $1,746,000, on April 6, 2011. The contract has been
completed in substantial conformance with the plans and
specifications approved by City Council.
This project consisted of constructing a stormwater pump station at the deep basin located in
DeBenedetti Park. The improvements included site improvements, mechanical trash removal racks,
piping, electrical building, standby emergency generator, electrical/instrumentation/controls, Supervisory
Control and Data Acquisition (SCADA) integration, and other incidental and related work.
The contract was completed by the contract completion date of December 5, 2011, including having the
pumps operational by October 15, 2011. The final contract price was $1,818,150.79. The difference
between the original contract amount and the final contract price is due to $72,150.79 in change orders.
The four change orders included:
Change Order No. 1 included additional concrete reinforcing required to meet code requirements and
owner -requested demolition of concrete at the south outfall structure ($7,256.90).
Change Order No. 2 included changes to the SCADA and PLC systems to permit remote operation of the
pump station from the Surface Water Treatment Facility and additional handrailing at the pump station
($24,411.31).

additional concrete reinforcing for the emergency generator ($34,805.26).

($5,677.32).
Following acceptance by the City Council, as required by law, the City Engineerwill file a Notice of

the project is complete and begins their 30 -day period to file a stop notice requiring the City to withhold
payments from the prime contractor in the event of a payment dispute.
FISCAL IMPACT: There will be an increase in the long-term power and maintenance costs for
the pump station and related equipment. Operating costs for the pump
