Adopt the attached resolution expressing Official Intent to Reimburse expenditures with proceeds of future enterprise fund debt for the repair and repainting of the one million gallon Calmont Elevated Storage Tank; 2. Adopt the attached appropriation ordinance reducing unallocated appropriations and increasing appropriations for the repair and repainting of one million gallon Calmont Elevated Storage Tank in the Water and Sewer Commercial Paper Fund in the amount of$799,000.00; and 3. Authorize the execution of a contract with A&M Construction & Utilities, Inc., in amount of$699,000.(0 for the repair and repainting of the one million gallon Calmont Elevated Storage Tank (City Project No. 100885). DISCUSSION: The Calmont one million gallon elevated storage tank was built in 1948 and last repainted in 1999. The existing coating has reached the end of useful life and needs to be removed and replaced in order to protect the structural steel from corrosion. On August 1, 2017, Mayor and Council Communication (M&C C-28304), the City Council authorized an` Engineering Agreement with a scope of work that included the preparation of plans and specifications Ar the Calmont Elevated Storage Tank Repair and Repainting Project. The project was advertised on November 16, 2017 and November 23, 2017, in the Fort Worth Star- Telegram. On December 21, 2017, the following bids were received: http://apps.cfwnet.org/eco6ncil/printmc.asp?id=25526&print=true&DocType=Print 113 3/15/2018 M&C-Council Agenda BIDDER BID AMOUNT CONTRACT A&M Construction Utilities, Inc. $699,000.00 135 calendar days N.G. Painting, L.P. $860,850.00 Blastco Texas $1,228,378.38 TMI Coatings, Inc. $1,230,000.00 American Suncraft $1,261,400.00 In addition to the contract cost, $50,000.00 is required for staff project management and $50,000.00 is provided for project contingencies. This project is anticipated to be included in a future revenue bond issue for the Water and Sewer Fund. Available cash within the Water and Sewer portfolio and the City's portfolio along with the appropriation authority authorized under the Callable Commercial Paper Program (CP)will be used to provide interim financing for this project until debt is issued. To the extent resources other than the Water and Sewer portfolio are used to provide interim financing, the Water and Sewer Fund will be charged interest that is equivalent to the overall rate of return being earned by the City portfolio (currently approximately one- percent annually). Should the City's portfolio not support the liquidity needed to provide an interim short- term financing source, another funding source will be required, which could mean issuance of securities under the CP Program or earlier issuance of Water and Sewer revenue bonds than is currently planned. Once debt associated with this project is sold, bond proceeds will be used to reimburse the Water and Sewer portfolio and the City's portfolio, in accordance with the attached Reimbursement Resolution. The City Council adopted the Water Department's Fiscal Year 2018-2022 Five-Year Capital Improvement Plan on December 12, 2017, Mayor and Council Communication (M&C G-19187). This City Council adopted plan includes this specific project,with funding identified through the CP program to be reimbursed with future revenue bonds. In accordance with the provisions of the Financial Management Policy Statement, Staff anticipates presenting revenue-supported debt issuances to the City Council for consideration within the next three years. This debt must be issued within approximately three years to provide reimbursement for these expenses. If that does not occur, the costs will no longer be reimbursable by issuing tax-exempt debt and the funding source will have to be made whole through other budgetary methods. Adoption of this resolution does not obligate the City to sell bonds, but preserves the ability to reimburse the City from tax-exempt bond proceeds. This project will have no impact on the Water Department's operating budget. The total cost for this project is estimated to be$1,100,000.00. Construction is anticipated to commence in March 2018. With contract time of 135 Calendar days, the construction is estimated to be completed by the end of August 2018. MJWBE OFFICE - A&M Construction & Utilities, Inc., is in compliance with the City's BDE Ordinance by committing to five percent MBE participation. The City's MBE goal on this project is five percent. Additionally, A&M Construction & Utilities, Inc., is a certified M/WBE firm. The project is located within the City Limits COUNCIL DISTICT 3. FISCAL INFORMATION /CERTIFICATION: The Director of Finance certifies that upon approval of the above recommendations and adoption of the attached appropriation ordinance funds will be available in the Water/Sewer Commercial Paper Fund for http://apps.cfwnet.org/ecouncil/printmc.asp?id=25526&print=true&DocType=Print 2/3 3/15/2018 M&C-Council Agenda the One Million Gallon Calmont Elevated Storage Tank Repaint and Rehabilitation Project. The Water and Sewer Commercial Paper Fund includes authority of$150,000,000.00 for the purpose of providing interim funding for Water and Sewer Capital Projects.
