DATE: TO: FROM August 2, 2010 Honorable Mayor and Members of the City Council through City Manager Pamela Tuft -Interim Director, Water Resources & Conservation SUBJECT: Resolution.Rafifyirig the Contract for the Adobe Creek Emergency Sewer Main Repair Project (066401105), Authorizing the Inclusion of the Necessary Budget Adjustment in the 1St Quarterly Budget Adjustment Ordinance and Approving the Project Budget RECOMMENDATION It is recommended that the City Council adopt the attached Resolution ratifying the contract. for ,,,,, , the Adobe Creek Emergency, Sewer Main Repair Project (066401:105), authorizing the inclusion of the necessary budget adjustment in the 1St Quarterly Budget Adjustment Ordinance and approving the project budget. BACKGROUND In 1978, in conjunction with the Casa de Arroyo Subdivision a 6" sanitary sewer main was installed under Adobe Creek approximately 150' north of Lakeville Hwy between Rancho Bonito Drive and Casa Verde Circle (see attached map). This section of pipe is approximately 140' in length. During a recent routine cleaning, the. equipment became jammed and an investigation into the reason was begun. Attempting to,linspect'the existing line via televised inspection proved to be a problem due to the inflow of groundwater into the main. . City Staff solicited bids from three local contractors to repair the sewer :main and to stop the infiltration. A Minor Construction Agreement was. executed with J., F. Pacific Liners, Inc.; of Vacaville; CA, to clean, :inspect and grout approximately 140 feet of 6" sewer pipe. During the first day on the job, Pacific Liners' crew could not patch any of the. breaks in the line due to the condition of"the pipe and had to pull offthe job. A$erreview of their inspection video, it became obvious that the pipe condition was too deteriorated to repair. Due to the location of the `pipe, under Adobe Creek, a decision to replace the pipe immediately under an emergency contract was determined to be the most environmentally sound action. Reduction of flow in the creek or'~the below surface groundwater could result in a flow of untreated wastewater out of the severely corroded pipe. Agenda Review: Dept. Directr City Attorney Finance Director City Manag „n,,,„. ~ , , i '~,,, Thiss sect S.CWA' ion of Adobe;;Creek is o;wred and,rnaintained by the Sonoma County Water Agency ~ er,:and ' h (y ~ '~ ). AC t Staff nohfiee Ito ent ;work within'the SCWA property has. been, obtained ~, b the~City. y d the 'Department of Fish and Game (DF&G) and the Regional Water Quality Control Board (RWQGB) about the emergency project. DISCUSSION The least intrusive option is to replace the existing sewer main using apipe-.bursting technique. This method consists of pulling a cutter 'head and a new 6" pipe fo "burst" thru the existing main while at the same time installing ~a;new "line. A pipe bursting .operation may not be physically possible due to the curvilinear alignment of the pipe, `the possibility of`concrete encasement, and an accumulation of significant gravel in the pipe section. A second' option is to lay a new 6" main by conventional methods. Option 1 does not involve in=creek work.. Option 2_ would require diverting creek flows with a temporary dam structure and',pipe to allow excavation and replacement. Restoration of creek area affected by the work would be .conducted immediately per regulatory permit conditions. SWCA, DF&G and RWQCB gall are aware ofthese options; City staff will keep there updated on the progress and will obtain any additional permits necessary for the emergency work. City Staff met. with Team Ghilotti,~''Inc., (TGI); of Petaluma, CA to 'discuss replacement options. TGI is local and large enough to complete'the job quickly and.effi~ently. The City negotiated a time and materials contract with TGI to include both courses of ;action. If the pipe bursting method is stopped due to the existing conditions, TGI'would immediately move to replace the pipe using conventional methods The other local, large firm; North Bay Construction, is not currently accepting new contract's pending purchase by Ghilotti Construction Co., in Santa Rosa, California. Team Ghilotti, Inc.. has performed ;similar projects for the City o f Petaluma. Staff verified that Team Ghilotti, Inc. possesses a valid ,Class A California Contractor's 'License, license number 895384, which expires on 4/30/201:1, that qualifies Team Ghilotti; nc. to perform the work. Due to.the serious nature of the event, a'contract was awarded. on an emergency basis for an amount not to exceed $155,000.
