NO 22 1990 <br />BOOK 82 PAGE' <br />' WEST REG. WASTEWATER TREATMENT PLANT EXPANSION, PHASE II <br />Capital Projects Engineer McCain reviewed the following: <br />DATE: NOVEMBER 15, 1990 <br />TO: JAMES E. CHANDLER <br />COUNTY ADMINISTRATOR <br />FROM: TERRANCE G. PINTO <br />DIRECTOR OF UTILITY SERVICES. <br />PREPARED WILLIAM McC <br />AND STAFFED CAP TS ENGINEER <br />BY: DEP OF UTILITY SERVICES <br />SUBJECT: WEST REGIONAL WASTEWATER TREATMENT PLANT EXPANSION <br />PHASE II <br />BACKGROUND <br />On March 10, 1987, the Board of County Commissioners approved Work <br />Authorization No. 11 with the firm of Masteller and Moler <br />Associates, Inc. for the design of the above -listed project. We are <br />now preparing to bid this job out sometime in late March or April. <br />Since the original design was completed, several changes in both <br />design and scope of engineering.services must be made. <br />ANALYSIS <br />An addendum to the above -listed Work Authorization is attached. An <br />exact description of the additional work is under Section I of that <br />document. There are two cost elements associated with this Work <br />Authorization --an additional $29,518.00 for basic engineering <br />services and an additional $8,100.00 for inspection. The total cost <br />for engineering services is well within the acceptable percentage <br />range. Funds for this work will come from the Wastewater Impact Fee <br />Funds. <br />RECOMMENDATION <br />The staff of t;he Department of Utility Services recommends that the <br />Board of County Commissioners approve the attached Work <br />Authorization with Masteller and Moler Associates, Inc. <br />Engineer McCain explained the the majority of what this is <br />covering will be a modified headwork system to the existing plant <br />and the new plant that has been previously designed, and it also <br />includes a force main out of the back of the plant to tie into an <br />existing force main that ultimately will go down to the Landfill <br />area. The other main change is that we are now looking to bring <br />more competition into the bidding by having the specs rewritten <br />to allow pour -in-place as we did with our North County wastewater <br />plant. <br />34 <br />
