City Manager CA Finance Director FROM: DOUGLAS S. STACK, DIRECTOR OF PUBLIC WORKS /CITY ENGINEER SUBJECT: APPROVE PLANS AND SPECIFICATIONS AND AUTHORIZE ADVERTISEMENT FOR BIDS FOR THE EDINGER AVENUE WELL PROJECT — PHASE I DRILLING CIP 60165 SUMMARY The plans and specifications for the Edinger Avenue Well Project — Phase I Drilling CIP 60165 have been prepared and the project is ready to be bid. RECOMMENDATION It is recommended that the City Council: 1. Appropriate $1,800,000 from the 2011 Water Revenue Bond Fund (Fund 305) to the Edinger Avenue Well Project — Phase I Drilling CIP 60165; and 2. Adopt Resolution No. 12 -90 approving the plans and specifications for the Edinger Avenue Well Project — Phase I Drilling CIP 60165, and authorize the City Clerk to advertise to receive bids. FISCAL IMPACT Sufficient funds, in the amount of $200,000, have been budgeted for the preliminary design phase of the Edinger Avenue Well Project in the Fiscal Year 2012 -2013 Capital Improvement Program Budget. Well drilling was planned for FY 2014/15. To advance Phase I Well Drilling, $1,800,000 will need to be appropriated from the bond proceeds from 2011 Water Revenue Bond issuance. There is a $5,000,000 fund balance in net bond proceeds in Fund 305. DISCUSSION The construction of the Edinger Avenue Well CIP 60165 has been advanced to coordinate with the construction of the Residence Inn and the Fairfield Inn by RD Olson Company and to complete the drilling phase of the project before the grand opening and occupancy of the hotels. The proposed project will be implemented in two phases: Phase I Drilling, and Phase II Construction /Equipping. This project will enable the City to improve its groundwater production and reliability. Ultimately, the well will be contained within in a structure that is approximately 2,000 square feet in size, designed to match and blend with the adjacent architecture and land use. The proposed well will be drilled in two passes (i.e. pilot borehole and reamed borehole) using the reverse circulation rotary drilling method with installation of a gravel envelope to stabilize the formation materials. A 17.5 -inch pilot borehole will be drilled to an estimated total depth of 1,300 feet. Edinger Avenue Well Project CIP 60165 October 16, 2012 Page 2 Once the pilot borehole has been drilled, a suite of geophysical logs will be obtained. Isolated aquifer zone testing will then be performed, the results of which will be used to quantify aquifer yield and ground water quality. This data will be instrumental for preparation of the final well design such that the best possible ground water quality can be achieved. Production rates for the proposed well are expected to range from approximately 1,500 gallons per minute (gpm) to 2,500 gpm. Drilling, construction, development, and testing of the well will require approximately 75 work days to complete (not including weekends). During that period of time several phases of the work will require 24 -hour continuous operations on the part of the drilling contractor. The number of work days required for each major phase of well installation, and the nature of that work (i.e., 24 -hour or daylight only) is summarized below: Conductor Installation 1 Daylight Only Mobilization Pilot Borehole Drilling Isolated Aquifer Zone Testing Well Construction Initial Well Development Demobilization of Drilling Rig / Mobilization of Test Pump & Motor Final Development Step Drawdown Aquifer Test 24 -Hour Constant Rate Aquifer Test Well Disinfection 5 Daylight Only 6 24 -Hour Continuous 8 24 -Hour Continuous 3 24 -Hour Continuous 7 24 -Hour Continuous 7 Daylight Only 6 Daylight Only 1 Daylight Only 2 24 -Hour Continuous 1 Daylight Only Gyroscopic & Video Surveys 1 Daylight Only Edinger Avenue Well Project CIP 60165 October 16, 2012 Page 3 The tentative project schedule for the drilling phase is as follows: • Authorization to Advertise for Bids ....................... .....................10 /16/2012 • First Legal Advertisement ....................... ............................... 10/18/2012 • Second Legal Advertisement ................... ............................... 10/25/2012 • Bid Opening ........................................ ............................... 11/19/2012 • Award of Contract... ... ......................................................... 12/04/2012 • Start Construction ................................ ............................... 01/15/2013 • Complete Construction .......................... ............................... 05/01/2013 Based on current material prices and recent bids for similar types projects, the estimated cost for drilling, constructing, development, construction management & engineering, testing, and contingency is approximately $ 1,800,000. The Edinger Avenue Well Project CIP 60165 is Categorically Exempt under California Environmental Quality Act (CEQA) requirements. A Notice of Exemption has been prepared for the project, and will be recorded with the County of Orange following Council approval of the plans and specifications. S.
