8. HDR Engineering Contract Amendment - Facility Plan 2000City of Kalispell Public Works Department Post Office Box 1997, Kalispell, Montana 59903-1997 - Telephone (406)758-7720, Fax (406)758-7831 REPORT TO: Mayor and City Council FROM: Jim Hansz, Director of Public Works SUBJECT: Amendment 1, Facility Planning Study MEETING DATE: October 1, 2001 BACKGROUND: During the course of the City's utility facility planning study a number of fundamental changes have occurred or have been proposed after the completion of the agreed upon scope of work tasks. These changes may have a material impact of the results of the study and should be evaluated for their significance. Among the changes are recently defined plans for development of Section 36 by DNRC, recently confirmed errors in flow measurement at the W WTP, and a new proposal for development of the Glacier Mall north of Evergreen. In particular, the flow measuring error at the W WTP is significant because this data is used to establish baselines for many other areas of analysis within the study. This problem was uncovered after the flow measurement equipment failed outright and was subsequently replaced. The consultant has submitted a proposal for performing all the required analysis of the new data and correcting all the baseline information throughout the planning document's eight sections where they are impacted. We have reviewed the amendment and the proposed hours and costs are consistent with the level of effort expected for this work and the unit rates agreed within the current contract. The total amount of this amendment is $21,647.50. This cost will be distributed between the individual enterprise funds according to the work performed. There are funds available for this work so that no change in budget is necessary. RECOMMENDATION: Staff recommends approval of Amendment #1 to the City's contract with HDR for Facility Plan 2000. ACTION REQUESTED: MOTION TO AUTHORIZE THE CITY MANAGER TO SIGN AMENDMENT #1 TO THE CONTRACT WITH HDR ENGINEERING, INC., FOR FACILITY PLAN 2000. FISCAL EFFECTS: Eventual expenditure of $21,647.50 with costs apportioned to the water, sewer and storm drain funds. No budget amendments will be necessary. ALTERNATIVES: As recommended by the City Council. Respectively submitted: James C. Hansz, Y.E. Director of Public Works/City Engineer Attachment: Amendment #1 C9'�,�/ Chris A.

Hansz Director of Public Works City of Kalispell P.O. Box 1997 Kalispell, MT 59903-1997 Subject: Kalispell — Facility Plan 2000 Amendment No. 1 Dear Jim: Please consider this request for additional funds associated with updating the Facility Plan to include detailed development plans for Section 36 based on DNRC's final environmental impact statement, development of the Nupac property, and the proposed development of Glacier Mall. This request also includes updating the report for corrected sewer flows to the WWTP due to the inaccuracy discovered in the old flowmeter. Following is a detailed description of the work associated with updating the facility plan to include these recent developments and a proposed budget for this work is attached: SECTION 2 - BASIS OF PLANNING: We will need to re -distribute the population/employment and evaluate the impact to overall population based on the information now available from DNRC, NuPac, and Glacier Mall. The re -distribution of population throughout the analysis zones will be used to update the hydraulic models. I have included two days of my time for revising the report, a day of Jeroen Olthof s time for re -distribution of the population. and a half -day of Dave Clark's time for his input on re -distribution of population and quality control review. SECTION 3 - WATER SYSTEM ANALYSIS: We will need to adjust the population/employment distribution in the model and analyze the system for deficiencies, etc. The report text will need to be revised based on the outcome of the analysis and changes in water demand that will most likely result. There will most likely be a fairly significant change in population from the lower to the upper zone. This will be a significant amount of work due to the number of alternatives and associated cost estimates included in the report. I have included three days of my time for revising the report, one and a half days for Jeroen Olthof to update the model and analyze the system, and a half -day of Dave Clark's time for quality control.

Montana Fax Employee Owned 59808 406 541-8131 Mr. Jim Hansz September 24, 2001 Page 2 SECTION 4 - SEWER COLLECTION SYSTEM ANALYSIS: We will need to analyze the flow records (past and present) and calculate new flow assignments for residential and commercial flows. This will also impact the inflow and infiltration analysis that was completed as part of this chapter. Jeroen Olthof will need to update the model and analyze the system for deficiencies, etc. Alternatives will need to be re-evaluated and cost estimates revised. I have estimated two days of my time for revising the report, a day and a half of Jeroen 01thoPs time for updating the model and analysis of the system, and a half -day of Dave Clark's time for quality control. SECTION 6 - WWTP ANALYSIS: Hours included in the budget for the WWTP includes Morrison Maierle, Inc. time to re -run their analysis of the WWTP based on updated sewer flows that will be developed by HDR staff as part of the sewer collection system analysis due to the inaccuracy discovered in the old plant flowmeter. Their time includes 6 days for Scott Murphy and 3 days for Terry Richmond. SECTION 7 — SYSTEM RECOMMENDATIONS AND CAPITAL IMPROVEMENT PLAN I have included a day and a half of my time for updating the water, sewer, and WWTP capital improvement plans based on revisions to cost estimates from the revised analysis (half -day per program) Please call if you have any comments or questions with regard to this amendment. Sincerely, Craig T Caprara HDR ENGINEERING, INC. Cc Terry Richmond Dave Clark
