RECOI'IMENDED ACTION Accept improvements under contract for Wastewater Main
Rehabilitation Program, Project No. 7.
BACKGROUND INFORMAT¡ON: This project consisted of trenchless rehabilitation of approximately
33,220linear feet of existing 6-inch, 8-inch, 12-inch, 18-inch, and
21 -inch diameter wastewater pipes, internally reinstating
approximately 600 wastewater laterals, rehabilitating 143 wastewater manholes, and other incidental and
related work, all as shown on the plans and specifications for the above project. Photos of manhole
rehabilitation are shown in Exhibit A.
The plans and specifications for this project were approved on February 7 ,2018. The contract was
awarded on April 18,2018, to Express Sewer & Drain, lnc., of Rancho Cordova, in the amount of
$1,885,814.
The original contract completion date was February 26,2019. The final contract completion date
(extended by change order) was June 8,2019; however, the work was completed on May 2,2019. The
final contract amount was $1,885,619, approximately $200 less than the original contract amount, due to
three change orders amounting to $187,799 and credits from reductions in contract line item quantities.
The total change orders, amounting to $187,799, were executed by the City Manager as authorized by
City Council on November 15, 2018.
Change Order No. 1 included the work necessary to rehabilitate 273lineal feet of pipeline originally
identified as 21 inches in diameter along Ham Lane that was actually 24 inches in diameter; additional
bypass pumping and night work to remove excessive scale on the existing cast iron pipe to facilitate
proper lining; and a complex point repair and asphalt patch at Ham Lane and Walnut Street
($10t,147.00).
Change Order No. 2 included additional, City requested video and cleaning of 804 lineal feet of
wastewater line (without lining) and seven open cut mainline service tap replacements which had
deteriorated and would cause future leaking and subgrade degradation ($34,716.00).
Change Order No. 3 included additional mainline service tap replacements, replacing a 23-lineal-foot
segment of eight-inch wastewater line to facilitate lining; installation of two additional manholes to
facilitate lining operations, and eliminating the lining portion of 709 lineal feet of wastewater lines which
were assessed and cleaned but left unlined due to good condition ($51,936.00).
Following acceptance by the City Council, as required by law, the City Engineer will file a Notice ot
Completion with the County Recorder's office. The notice serves to notify vendors and subcontractors
