SUBJECT
(ALL) Authorize Agreement with H & H Concrete On Demand Inc. for Volumetric Mixer Trucks and Concrete/Foowable Fill Services in
an Annual Amount Up to $2,500,000.00 for the Initial Term and Authorize Four One -Year Renewals Options in an Amount Up to $2,875,000.00 for
the First Renewal, $3,306,250.00 for the Second Renewal, $3,802,188.00 for the Third Renewal, and $4,372,516.00 for the Fourth Renewal for
the Water Department
RECOMMENDATION:
It is recommended that the City Council authorize the execution of an agreement with H & H Concrete On Demand Inc. for volumetric mixer trucks
and concrete/flowable fill services in an annual amount up to $2,500,000.00 for the initial term and authorize four one-year renewals options in an
amount up to $2,875,000.00 for the first renewal, $3,306,250.00 for the second renewal, $3,802,188.00 for the third renewal, and
$4,372,516.00 for the fourth renewal for the Water Department.
DISCUSSION:
The Water Department approached the Purchasing Division to procure an agreement for labor, materials, parts, volumetric truck(s), and
equipment necessary to perform concrete and flowable fill services at various locations around the City for street repairs. In order to procure these
services, Purchasing staff issued Request for Proposals (RFP) No. 24-0188. The RFP consisted of detailed specifications describing the
proposed responsibilities and service requirements.
The bid was advertised in the Fort Worth Star -Telegram on April 17, 2024, April 24, 2024, May 1, 2024, May 8, 2024, and May 15, 2024. The City
received four (4) responses. Upon review, David-Tehoungue Ltd Co and Massey Bros Concrete did not submit all the required documents in order
for their proposals to be evaluated and were deemed nonresponsive.
An evaluation panel consisting of representatives from the Water Department and Transportation & Public Works Department reviewed and
scored the proposals using Best Value criteria. The individual scores were averaged for each of the criteria and the final scores are listed in the
table below. No guarantee was made that a specific amount of services would be purchased.

Cornerstone Ontime Concrete, LLC15.50 15.50 15.63 16.53 1 63.16C
Best Value Criteria:
• a. Qualifications and Experience
• b. Approach to perform services
• c. Ability to meet the City's needs
• d. Cost
After evaluation, the panel concluded that H & H Concrete On Demand Inc. presented the best value to the City. Therefore, the panel recommends
that the City Council authorize an agreement for volumetric mixer truck(s), concrete, and flowable fill services for street repairs with H & H Concrete
On Demand Inc. Staff certifies that the recommended vendor met the proposal specifications.
FUNDING: The maximum amount allowed under the agreement for the initial year will be $2,500,000.00; however, the actual amount used will be
based on the needs of the department and available budget.
Department Account Name Agreement Total Amount
Water Water Street Repair $2,500,000.00
Funding is budgeted in the General Operating & Maintenance category in the Water & Sewer Fund for the Water Department.
DVIN-BE: A waiver of the goal for Business Equity subcontracting requirement is approved by the DVIN-BE, in accordance with the Business
Equity Ordinance, because the purchase of goods or services is from sources where subcontracting or supplier opportunities are negligible.
AGREEMENT TERMS: Upon City Council approval, this agreement shall begin upon execution and expire one (1) year from that date.
RENEWAL TERMS: The agreement may be renewed for four additional one-year terms. The spending authority for the renewal periods, if
exercised, will be in an amount up to $2,875,000.00 for the first renewal, $3,306,250.00 for the second renewal, $3,802,188.00 for the third
renewal, and $4,372,516.00 for the fourth renewal. This action does not require specific City Council approval provided that the City Council has
appropriated sufficient funds to satisfy the City's obligations during the renewal term.
ADMINISTRATIVE CHANGE ORDER: An administrative change order or increase may be made by the City Manager up to the amount allowed by
relevant law and the Fort Worth City Code and does not require specific City Council approval as long as sufficient funds have been appropriated.
FISCAL INFORMATION / CERTIFICATION:
The Director of Finance certifies that upon approval of the recommendation, funds are available in the current operating budget, as previously
appropriated, in the Water & Sewer Fund. Prior to an expenditure being incurred, the Water Department has the responsibility to validate the
availability of funds.
