Subject: Approve an annual purchase agreement with Martin Marietta
Materials, Inc. for aggregate street materials through an
Interlocal Agreement (ILA) with the City of Grapevine in an
amount not to exceed $75,000
Action
Requested: Approve an annual purchase agreement with Martin Marietta
Materials, Inc. for aggregate street materials through an Interlocal
Agreement (ILA) with the City of Grapevine in an amount not to
exceed $75,000.
Background
Information: Various divisions of Public Works require the purchase of
aggregate materials such as cement treated road base (CTB),
cement treated sand (CTS), and rock. These materials are
necessary to repair street failures and to facilitate utility repairs
under pavement.
The City’s bidding process for this contract award was met through
an Interlocal Agreement (ILA) with the City of Grapevine. Chapter
271 of the Texas Local Government Code allows governmental
entities to enter into an ILA with other governmental entities to
share contracts which have met the statutory bidding requirements
as prescribed by the State of Texas. The City of Southlake has
such an agreement with the City of Grapevine (Attachment A).
In October 2018, the City of Grapevine renewed its contract
RFQ458-2017 for the purchase of aggregate materials to Martin
Marietta Materials, Inc. (Attachment C). This renewal is the first of
four one-year renewal options. Line item pricing is provided in the
City Council packet (Attachment C).
Martin Marietta Materials, Inc. is the sole source provider of CTB
and CTS. These materials are produced in the DFW Metroplex and
have a shelf life of approximately three hours. Therefore, the
material must be purchased locally.

With the favorable pricing received in this contract and our
experience with the vendor, staff recommends approval of the
annual purchase agreement with Martin Marietta Materials, Inc.
Financial
Considerations: Funding for this contract is budgeted in the FY 2019 annual
operating budget for the Streets & Drainage Division and the FY
2019 Capital Improvements Program (CIP) Pavement Management
Assessment (PMA) budget. Expenditures will not exceed budgeted
funds.
For the past four fiscal years, the City has spent the following with
Martin Marietta Materials, Inc.:
FY 2015, $ 154,087
FY 2016, $ 149,225
FY 2017, $ 69,643
FY 2018, $ 23,835
FY 2019, $ 9,682 (to date)
Costs incurred for previous fiscal years (FY 2015 – FY 2017) were
due to the fact that several major roadways needed to be
reconstructed (S. White Chapel Blvd., Shady Oaks Dr., and N.
Peytonville Ave). This reconstruction effort required additional
material--above and beyond what is normally required for a simple
mill and overlay project. The majority of completed projects from
FY 2017 to present was specifically mill and overlay projects.
Strategic Link: This item relates to the City’s strategy map focus areas of
Infrastructure and Partnerships & Volunteerism. It specifically
relates to the City’s Corporate Objectives of (B2) collaborate with
select partners to implement service solutions and (F2) invest to
provide & maintain high quality public assets.

Martin Marietta has a division called Cement Treated Materials (CTM) that produces cementitious products
such as cement treated base and cement stabilized sand (backfill). These type of materials are produced
at an optimum moisture content that require compaction during placement. Due to the low moisture
content, it is best for these products to be produced in a pug mill plant to provide the best consistency.
Martin Marietta has been operating pug mills for over 37 plus years. We have one stationary pug mill plant
located in Dallas, TX, and another in Celina, TX, that produces these type of materials to the general public,
with the capability to produce a wide assortment of mixes, to cater to various requirements and
specifications. To the best of my knowledge, Martin Marietta has the only pug mill plant located in the
DFW area that produces cement treated base and cement treated sand to the general public. We currently
produce materials for several municipalities throughout Dallas County and Tarrant County.
If you a have any questions or need more information, please contact me at 214-502-4935.

Attn: Joe Walsh
Martin Marietta has developed a slurry system called SuperSlurry™ which produces cementitious products.
With the SuperSlurry system, Martin Marietta has two products that it produces into slurry. One product is
cement slurry and the other is Cem-Lime.
At significant cost to itself, Martin Marietta has developed the processes and components necessary to
manufacture SuperSlurry through internal experimentation, expertise and inventiveness. However, because
of the proprietary nature of the SuperSlurry products, manufacturing processes and delivery system, Martin
Marietta believes that it is the sole supplier that can provide you with SuperSlurry or its equivalent in north
central Texas and DFW metroplex.
Martin Marietta will license the SuperSlurry production process so that SuperSlurry will be widely available
wherever it is needed. However, we intend to protect the proprietary nature of the product and processes
so that only licensed suppliers will be allowed to produce and sell the SuperSlurry products to the quality
standards established by Martin Marietta. At the present time, Martin Marietta has not licensed any other
suppliers of SuperSlurry within the north central Texas or DFW area, so it remains the sole supplier in these
areas.
If you have any questions or need more information, please contact me at 972-409-3240.
