RG TOWN OF ORO VALLEY COUN1CIL COMMUNICATION MEETING DATE: February 9, 1998 TO: HONORABLE MAYOR & COUNCIL FROM: Don Chatfield, Community Development Director SUBJECT: LRSP Heritage Fund Project for Dennis Weaver Park; Award of General Contractor Bid SUMMARY: In December of 1997, the Town secured the services of an architecture firm as the first step towards initiating proposed Local. Regional. and State Parks Heritage Fund Grant renovations to Dennis Weaver Park. Since that time, schematic and design development has been completed, construction plans and bid documents released, and the Town has awarded the bids on the materials and equipment to be installed including sports lighting, playground equipment, as well as shade structures and additional cool decking for the swimming v pool facility. On Thursday, February 5. 1998, bids were opened for General Contractor services to perform these improvements. The Base Bid calls for the installation of those improvements outlined above including additional deck space at the northwest and south ends of the swimming pool. The development of these specific areas at the swimming pool were determined by the consultant architect to be the most critical in meeting the needs of both public swimmers and swim meet spectators respectively. Add Alternate #1 provides for additional deck space near the southeast corner of the swimming pool near the starting blocks, so as to alleviatep otential participant congestion problems during swim meets. Add Alternate #2 expands on this same idea by continuing the deck space further north, along the east side of the swimming pool. If approved, Add Alternate #2 would also help maintain a more symmetrical form to the overall swimming pool perimeter. These two Add Alternates were listed in this fashion so as to provide the Town with several options to consider once the final bid results were compared to the available project budget. At the time when the bid documents were released, it was felt that this was the one area where deductions could be made, if it became necessary, to keep the overall project within budget. After a review and subsequent investigation of the bids by the Town's consultant architect, it was discovered that the apparent low bidder. TG Construction Incorporated, made several key mistakes in estimating their bid proposal. Because of these inaccuracies, this General Contracting firm has requested to withdraw their bid proposal. Since the proposal of the next low bidder is accurate, only moderately higher. and is well within the approved project budget, the consultant architect is recommending that the Town approve the withdrawal request submitted by TG Construction Incorporated and subsequently award the project bid to Peck Enterprises Incorporated. While the Town could certainly require TG Construction Incorporated to honor their original bid proposal or risk forfeiting it's bid bond, this would most likely create a difficult working relationship from the outset. The Town would have to continually deal with a less than cooperative General Contracting firm who might be looking to "cut corners" in the quality of their workmanship, as a means to prevent any further profit loss. • STAFF RECOMMENDATION: Given the short time frames involved and since the Base Bid and Add Alternate items are all well within the budget, staff would recommend that the project be awarded to Peck Enterprises Incorporated as recommended by the Architecture Company. FISCAL IMPACT: $106,600 (General Fund: LRSP Heritage Fund Grant) ATTACHMENTS: 1. Minutes of February 5, 1998 Bid Opening 2. Bid Recommendation from Architect SUGGESTED MOTION: I make a motion to award the Base Bid, Add Alternate #1, and Add alternate #2 for General Contractor Services to orm f erproposed LRSP Heritage Fund Renovations at Dennis Weaver Park to Peck Enterprises P Incorporated, in the amount not to exceed $106,600. gr I 4.

Hook, P.E. Town Engineer SUBJECT: Project No. WO1-0198 Town of Oro Valley Water Utility Well#23 New "C" Zone Potable Water Production Well SUMMARY: Per the direction of Mayor and Council, and through the Town of Oro Valley Water Utilities Commercial Readiness Program, plans and specifications were provided for the acceptance of public bids for the following project: Town of Oro Valley Water Utility Well#23 New "C" Zone Potable Water Production Well Two alternate methods of drilling were specified in the contract documents for the project. The first drilling method as listed in Bid Alternative"A"was for drilling a potable water supply well employing the reverse-circulation rotary drilling method with a 16"wire-wrapped well screen. The second drilling method as specified in Bid Alternative "B" was for drilling a potable water supply well using the cable-tool drilling method with a 16" milled slotted casing. Bids were received for both methods of drilling to evaluate the most cost-effective method of drilling. The low bid for a well employing the reverse circulation rotary drilling method was $130,262.50. The low bid price for drilling the new well using the cable tool method was $86,748.00. The total up-front capital cost difference between the two drilling methods is $43,514.50 (see Attachment A). Two criteria were used in the evaluation of the two drilling methods: 1) Up front capital cost, and 2) Long-term energy cost. The second criteria is primarily related to the efficiency differences between the wire-wrapped screen used in the reverse circulation drilling method as it compares to the milled slotted pipe used within the cable-tool drilling method. The analysis determined that a well drilled using the reverse circulation rotary drilling method with a wire-wrapped screen provides a present value energy cost savings of approximately$78,500.00 (see Attachment B). \\Thom as\c-drive\tovwu\C O M M READ I\well.c omm.ltr.wpd TOWN OF ORO VALLEY COUNCIL COMMUNICATION PAGE 2 OF 2 ATTACHMENTS: (Attachment A) Bid Opening Tabulation, Project No. WO1-0198 (Attachment B) Technical Memo Evaluating Drilling Methods FISCAL IMPACT: The total amount bid by the low bidder was$130,262.50 by Arizona Beeman Drilling,the Engineer's Cost Estimate for this project was $135,000.00.

FROM: BUCK SCHMIDT,GER-AGHTY&MILLER,INC. RE: CST-BENEFIT ANALYSIS OF TWO ALTERNATE WELL CONSTRUCTION METHODS AND PRE-BID OPEN-AREA DESIGNS FOR NEW ORO VALLEY WELL#23 A cost-benefit analysis was conducted on two alternate well construction methods and open-area designs for the construction of the new Oro Valley Well #23. The basis of the analysis is comparing the difference in the initial capital costs to the potential long-term operational costs of purnoing.The alternate construction methods include the cable tool and reverse-circulation rotary methods. The open-area design using the cable tool method utilizes mill slotted pipe while the reverse-circulation rotary method utilizes wire-wrapped screen. (Wire-wrapped screens typically can not be used for the open-area of a cable tool constructed well due to compressive strength requirements needed for installation by the cable tool method.) Bid costs of construction were received from well construction contractors for these two alternate methods and open-area designs. The initial capital costs of constructing a well by the reverse-circulation rotar•, method with wire- wrapped screen are typically significantly greater than constructing a well by the cable tool method with mill slotted pipe. However, the long-term operational costs of pumping of a reverse-circulation rotarT, constructed well with wt-ire-wrapped screen are often significantly less due to greater efficiency v of the open area. Contractors understand that price will not be the only criteria considered in selecting the wining bid. The criteria language included in the invitation for Bids of the bid document is restated below: "Each drilling method will be considered. Time to complete the well, and the potential capacity and/or efficiency differences of a well constructed by the optional drilling methods will be equally evaluated along with price." Bids received from prospective well construction contractors illustrate the significant difference between the initial capital costs of the competing construction methods and open-area designs. The low bid cost using the cable tool method with mill slotted pipe was received from Farwest Pump Company. Their bid cost was for $86,748.00. The low bid cost using the reverse-circulation rotary method with wire-wrapped screen was received from Arizona Beeman Drilling, Inc. Their bid cost was for S130,262.50. The difference of the initial capital costs of wells constructed by the competing construction methods is $43,514.50. Recommending using the more expensive reverse-circulation rotary method with wire-wrapped screen for the construction of Oro Valley Well #23, the potential benefit realized by a reduction in operational costs would require a cost saving of at least this amount in present value dollars for the life of the well. 12/30/97 1 MEMORADUM: EVALUATION OF WELL#23 CONSTRUCTION BIDS COST-BENEFIT ANALYSIS ToP erform the cost-benefit analysis, operational costs of wells constructed by the competing construction methods and open-area designs were evaluated from information in scientific literature and from hydraulic information from wells previously drilled in the vicinity of the Well #23 drill site. J Operational costs of pumping are directly proportional to the depth by which groundwater is produced from the well. Designs of wells can not influence the depth to which groundwater is encountered in the aquifer,but can influence the amount of drawdown induced by pumping. A paper P Johnson resented in The Driller's Journal (1982) presents an analysis of drawdown of 30 wells constructed either with louvered or mill slotted pipe, or wire-wrappedscreens. A copy of thisPaP er is attached as Attachment #1. The analysis indicated that no wells have a geologic advantage as illustrated by the well site map included in the paper. Average drawdown of 19 of these wells constructed with louvered or mill slotted pipe was 96.7 feet pumping at 2,500 gallons per minute 'gym). Average drawdown of the remaining 11 wells constructed with wire-wrapped screens was 36.4 feetP umping at 2,500 gpm. This information indicated that drawdown is about 62% or an average of 60.3 feet less in the wells constructed with wire-wrapped screen in comparison to the wells constructed with louvered or mill slotted pipe. As a result of the decreased lift required by these wells, operational cost of pumping is greatly reduced. Usingm 2,000 hours of operation time per year, electricity cost of 7 cents per kilowatt-hour, and an overall pump efficiency of 65%, an average annual saving of pumping costs per well is calculated as 56,116 for the wells constructed with wire- wrapped screen. A similar analysis wasP erformed on two wells located within 2,000 feet of the Well #23 drill site which were constructed by the two competing construction methods and open-area designs. The is included as Attachment #2. One well is C r c� Valley le�: ��ell #18, analysis including assumptions which was constructed by the cable tool method with mill slotted pipe. The second well is Tucson Water Well C-113 A, which was constructed by the reverse-circulation rotary method with wire- wrappedtests conducted on the respective wells shortlyafter construction indicated screen. Pumping - that dra\vdo\vn is 39.2 feet less pumping at 1,500 gpm in the well constructed by the reverse- circulation rotar,- method with wire-wrapped screen in contrast to the well constructed by the cable tool mete.Dd with mill slottedP ipe. Using 6,570 hours of operation time per year 73° of total year), electricity cost of 8 cents per kilowatt hour,and an overall pump efficiency of 8500, an annual savings ofPg nPum ig costs is 56,843 for the well constructed with wire-wrapped screen. a..mo:zizing this . difference in um ing cost to thepresent value assuming an interest rate of 6°0 and a 20 year well P P of present is Usinga r life, the savings difference pumping costs in present value dollars about 578,500. more � annual savingsof pumpingcosts is 58,943 with a present realistic overall pump efficiency of 65%,an annual value over 20 years of about S 102,600. RECOMMENDATION The above cost-benefit-benefit analysis which compared the initial capital costs and potential long-term operational costs of pumping of the competing construction methods and open-area designs, supports the reverse-circulation drilling method with wire-wrapped screen as the preferred alternative for the construction of new Oro Valley Well #23. This is supported by the reduction in pumping costs for the life of the well inresent value dollars which far exceeds the difference in initial capital costs of 543,�,514.50- . Additionally,P sand production has been a problem in a number of Oro Valley wells drilled by the cable tool method with mill slotted pipe, and experience indicates that wells with J wire-wrapped screens are far superior in controlling potential sand production. Furthermore, construction time using the reverse-circulation rotary method is typically less than using the cable V tool method, which is also advantageous in meeting the Oro Valley Water Utility's commercial readiness schedule.

Q C7 n. 4 TOWN OF ORO VALLEY COUNCIL COMMUNICATION MEETING DATE: February 9, 1998 TO: HONORABLE MAYOR & COUNCIL FROM: David G. Hook, P.E. Town Engineer SUBJECT: Project No. W03-0398 Town of Oro Valley Water Utility Startup Telemetry Projects SUMMARY: In accordance with the water system requirements and the Town of Oro Valley Water Utilities Commercial Readiness Program, plans and specifications were provided for the acceptance of public bids for the following project: Town of Oro Valley Water Utility Startup Telemetry Projects Per the Town of Oro Valley's Commercial Readiness Program, several new facilities are to be incorporated into the existing water utility system. All of the proposed facilities, as well as the existing facilities,are interrelated with respect to control of the water system. Due to the complexity of controlling both the existing and future systems, newer technology is required to control the water system. This newer technology entails installing Programmable Logic Controllers (Computers)that control the operations at each site. The Computers at each site will communicate with other sites via radio communications. The sites will also communicate with a central monitoring station that will be located at the water utility office. This will allow water utility staff to monitor operations of the system and will act as an early warning system if there are problems in the existing system. Five sites have been identified that will require a new type of control system as the result of the facilities to be constructed under the Commercial Readiness Program. These sites include: Water Plant#1 within the Rancho Vistoso Service Area Water Plant#10 within the Ranch Vistoso Service Area Water Plant#18 within the Canada Hills Service Area Water Plant#23 within the Canada Hills Service Area Deer Run Water Plant within the Canada Hills Service Area The low bid costs for equipping the five sites, as referenced above, is $72,151.00. The cost for installation of the Control Center is $25,629.00. The total cost submitted for the project by the low bidder also includes two radio repeater stations, which may not be required, for a total project cost of $114,425.00. The low bidder for the project is Interactive Controls, Inc. which is located locally in Tucson. \\Thomas\c-drive\tovwu\COMMREADI\telem.comm.ltr.wpd TOWN OF ORO VALLEY COUNCIL COMMUNICATION PAGE 2 OF 2 ATTACHMENT: Bid Opening Tabulation Project No. W03-0398 FISCAL IMPACT: The total amount bid by the low bidder was $114,425.00 by Interactive Controls, Inc.
