Subject: Approve contract with Geo Surfaces, Inc. for the purchase
and installation of synthetic turf on Field #9 at
Bicentennial Park through a TIPS Cooperative Purchasing
Contract for an amount not to exceed of $150,000
Action
Requested: City Council approval of a contract with Geo Surfaces, Inc., for
the purchase and installation of synthetic turf on Field #9 in
Bicentennial Park for an amount not to exceed $150,000
Background
Information: On March 16, 2018, City Council approved a request from
Dragon Youth Baseball (DYB) for SPDC Matching Funds
project in the amount of $75,000 (half of total project cost of
$150,000) for installation of synthetic turf on Field 9 infield at
Bicentennial Park. DYB submitted their share of the matching
funds of $75,000 to the City in February 2019.
The Scope of the project includes all materials, labor and
equipment necessary to install the synthetic turf and drainage
blanket on a structural base system and perimeter anchor.
The field will be solid green with a clay-colored infield and
home plate circle with permanently inlaid white foul lines,
coach’s boxes and batters boxes. A rendering of the field is
included with the proposal. Installation is estimated to be
completed in approximately 25 good weather working days
upon approval of the contract.
Geo Surfaces, Inc. submitted a Proposal to the City of
Southlake for the project in the amount of $142,000. The
$8,000 remaining funds for the project may cover additional
unforeseen expenses for this project or related expenses for
Field #9.

B. PHYSICAL PERFORMANCE CRITERIA:
The replicated grass surface shall demonstrate by independent, certified laboratory testing:
• A minimum average Tuft-Bind (ASTM D-1335) of 8 lbs/force.
• A minimum breaking strength (ASTM D-2256) of 250/250 (x and y direction) lbs/force.
• An initial G-Max (ASTM F-355-A) for the GeoGreen replicated grass of 135 in conjunction with GeoFlo drainage blanket and shock pad.

pad.
• An initial G-Max (ASTM F-355-A) for the GeoTrax warning track surface of 165 in conjunction with GeoFlo dynamic drainage blanket and
shock pad.
• An Ultimate G-max (TSI 128) for the GeoTrax warning track surface of 200 in conjunction with GeoFlo dynamic drainage blanket and
shock pad.
IV. INSTALLATION
A. BASE CONSTRUCTION – TURF INSTALLATION:
Specific design criteria must include the following:
1) The sub-base must slope a minimum of 1/4% (to a maximum of 1%) to ensure positive drainage to the perimeters of the fields.
2) After sub-base has been properly graded, contoured and sloped as required, it shall be compacted as close as possible to 95% Proctor
Density.
3) Install GeoBase reinforced concrete deck over entire base to be covered with drainage blanket and turf.
4) On the outside of the GeoBase structural deck, a 2” X 4” treated nailer will be attached by tap con or ramset. This anchor will act as the
perimeter anchor and the artificial turf will be stapled to this anchor.
B. GEOFLO DRAINAGE BLANKET INSTALLATION:
1) The concrete base should not deviate from specified finish grade by more than 1/4 inch under ten feet straight edge.
2) Blanket will be installed along full end-to-end length of the field, perpendicular to the direction of slope. The 4 feet wide rows should be
installed over the entire area of the artificial turf field . The installation of the rows of GeoFlo will continue in this manner until over the
open stone of the perimeter collector drains, where a 2’ wide row of pervious (perforated) Geo Flo will be placed, in the same manner.
The rows of GeoFlo will be bonded and moisture sealed, using a pressure-sensitive tape as supplied by Geo-Surfaces, on all seams. All
seams will be sufficiently tight to leave no gaps or irregularities that could reflect through the synthetic grass surface, however, care
should be taken to maintain a minimum 1/4 inch separation to allow for thermal expansion. The drainage blanket may be tempora rily
held in place by stapling to wood nailer, every few feet.
3) The dynamic drainage blanket will consist of a high density, cupsated core, sandwiched between a needle punched non -woven geotextile
on one side and a heat-bonded non-woven geotextile on the other side. Alternately, the fabric may be adhered to only one or non e of
the sides as determined by the manufacturer to be optimal configuration for prevailing soil and turf construction.
4) Total weight of blanket will be a minimum of 28 oz./sy and capable of accepting a compressive load of 15,000 psf, without crushing and
while maintaining measurable flow.
5) The GeoFlo drainage blanket will have a core incorporating expansion joints every 4 feet . The drainage blanket so constructed, must
provide a complete underlayment, over the entire field area, when mechanically bound with mechanical tape; and must not wrinkle,
wave, float, buckle or otherwise disturb the planarity of the artificial turf surface, even under the most elevated condition s for thermal
expansion to be experienced at the site.
6) The thickness of the blanket will be a minimum of 0.4 inch.

C. REPLICATED GRASS INSTALLATION:
1) The replicated grass will be installed along the length of the field and cover the full width as shown in the shop drawings. The carpet rolls
are to be installed directly over the properly prepared dynamic drainage blanket base. Extreme care should be take n to avoid disturbing
the drainage blanket. The full width rolls shall be laid out across the field. Utilizing standard state -of-the-art bonding procedures, each
roll shall be attached to the next. When all of the rolls of the playing surface have been ins talled, the sideline areas shall be installed at
right angles to the playing field turf. Turf shall be attached, by industrial rustproof staples directly to wood nailer, arou nd perimeter of
field at maximum three-inch (3 inch) intervals.
2) The replicated grass rolls shall be installed so that tufted lines are placed as shown on manufacturer's drawing, which drawing shall be
pre-approved by Purchaser prior to manufacture of replicated grass. The same drawing shall also show location of all optional in situ
permanent lines or markings.
3) Immediately after brushing with a motorized rotary nylon broom, the blended infill material shall be spread evenly by using a drop or
broadcast spreader (minimum 5 foot wide), in multiple applications, each no more than 15% of the total application, at a uniform rate.
Between applications, and just prior and subsequent to infilling the area shall be brushed with the motorized broom. Infill d epth will be
1.25 inches (1.25”+/- 0.1”), infill material to be uniformly incorporated into the replicated grass system.
PROJECT CLOSEOUT/WARRANTY: Upon final acceptance or first use of the finished sports field (whichever occurs first) the GeoSurfaces
Warranty becomes effective, which warranty shall be the only warranty obligation by GeoSurfaces to the Owner.
