Amendment No. 2-Scope of Work
City of Fort Worth
Village Creek WRF Thickening Modifications
City Contract No. CO2647
Amendment No. 2
The scope set forth herein defines the work to be performed by the ENGINEER. Both the
CITY and ENGINEER have attempted to clearly define the work to be performed to address
the needs of the CITY.
DESCRIPTION OF SERVICES
The Village Creek Water Reclamation Facility (VCWRF) is experiencing increased solids
loadings to its gravity thickeners, less thickened solids being pumped from the gravity
thickeners and an increase in sludge wasting rates to the gravity belt thickeners and DAFTs.
Upon investigation, plant staff determined the sludge drawoff box serving Final Clarifier 20
sludge gate has pulled from the wall and it is suspected the drain gate is leaking and
sending RAS to the primary clarifiers. This scope of work is providing recommended
improvements to the sludge drawoff box as well as other operational improvements related
to the plant's excessive solids.
WORK TO BE PERFORMED

Reclamation Facility Thickener Process Improvement project for sludge thickening improvements.
DISCUSSION:
The Village Creek Water Reclamation Facility ("VCWRF"), a 166 million gallons per day (MGD) plant,
comprised of primary, secondary and tertiary treatment, chlorine disinfection, and de-chlorination. The
VCWRF produces anaerobically digested biosolids, which are processed at the Biosolids Dewatering and
Processing Facility.
The VCWRF currently uses three solids thickening processes; Gravity Thickeners ("GT") to thicken the
primary solids from the primary clarifiers, Dissolved Air Flotation Thickeners ("DAFTs")to thicken the
solids from the Aeration Basins/Final Clarifiers and Gravity Belt Thickeners ("GBTs") to thicken the solids
from the high rate clarifiers. The existing GTs and DAFTs equipment are old, require a great deal of
maintenance, are inefficient in producing required levels of treatment, use a high amount of energy and
are sensitive to changes in flow characteristics. The proposed construction contract includes the
installation of new rotary drum thickeners (RDTs) to thicken solids from the primary clarifiers and high-rate
clarifier, the installation of new gravity belt thickeners GBTs and modification of the existing GBTs to
thicken secondary solids, modification of two gravity thickeners into primary solids holding tanks, and
retirement of the DAFTs.
On August 25, 2015 (M&C C-27433), the City Council authorized an Engineering Agreement with Freese
& Nichols, Inc. (CSC No. 47018), in the amount of$295,113.00, for study, evaluation and conceptual
design of thickening processes at VCWRF. On August 1, 2017 (M&C C-28317), the City Council
http://apps.cfwnet.org/ecouncil/printme.asp?id=28033&print=true&DocType=Print 9/27/2021
authorized an Engineering Agreement with Freese & Nichols, Inc., (CSC No. 49500), in the amount of
$1,809,500.00 to evaluate and design the Sludge Thickening Processes at the VCWRF.
As part of Amendment No. 1, the Engineer will perform basic construction support services including shop
drawings and submittals reviews, change order review, record drawings and update plant operational
preparation.
Construction of the project was advertised for bid on April 16, 2020 and April 23, 2020 in the Fort Worth
Star-Telegram. On May 21, 2020 the following bids were received:

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 2.3
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.
Tittn-//annc cfxxmPt me/Pr.rninril/nrintmc aen?id=?.R(II'1RTnrint=tf•ne&.noeTvne=Print 9/9.7/9,(121
The City Council adopted the Water Department's Fiscal Year 2020-2024 Five-Year Capital Improvement
Plan on September 17, 2019. 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 Statements, 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.
M/WBE OFFICE: Eagle Contracting LP is in compliance with the City's BDE Ordinance by committing to
10 percent MBE participation on this project. The City's MBE goal on this project is nine percent.
M/WBE OFFICE: Freese & Nichols, Inc. is in compliance with the City's BDE Ordinance by committing to
15 percent SBE participation on this Amendment No. 1. The City's goal on the Amendment No. 1 is seven
percent.
The project is located in COUNCIL DISTRICT 5, VCWRF services all COUNCIL DISTRICTS, Mapsco
90J, 90Q, and 90S.
FISCAL INFORMATION /CERTIFICATION:
The Director of Finance certifies upon approval of the above recommendations and adoption of the
attached appropriation ordinance, funds will be available in the Water& Sewer Commercial Paper(W&S
Commercial Paper) Fund for the VCWRF Thickener Process Improvement project to support the approval
of the above recommendation and execution of the amendment to the engineering agreement and
construction contract. Prior to an expenditure being incurred, the Water Department has the responsibility
