Specifications include, but are not limited to: a. Synthetic Turf shall be a tufted, slit-film, fibrillated, polyethylene, grass-like fiber with a primary and secondary backing. The fibers shall be tufted to a finished pile height of 2.5 inches. The SBR rubber infill shall be derived from 100% recycled Nebraska tires.; b. All components and their installation method shall be designed and manufactured for use on outdoor athletic fields. The materials as hereinafter specified, should be able to withstand full climatic exposure in Omaha, Nebraska, be resistant to insect infestation, rot, fungus and mildew; to ultraviolet light and heat degradation, and shall have the basic characteristic of flow-through drainage allowing free movement of surface run-off vertically through the synthetic turf system.; c. The finished playing surface shall appear as mowed grass with no irregularities and shall afford excellent traction for conventional athletic shoes of all types. The finished surface shall resist abrasion and cutting from normal use. The system shall be suitable for football, soccer, PE classes, intramurals, marching band and recreational use.; d. Pile yarn (silt-film fibrillated polyethylene) shall be proven athletic caliber yarn designed specifically for outdoor use and stabilized to resist the effects of ultraviolet degradation, heat, foot traffic, water and airborne pollutants.; f. Infill material shall be 100% certified State of Nebraska recycled tire SBR rubber granules.; g. Shock Absorbency of the Synthetic Turf System: (a) Player protection is an important aspect of athletic field performance for natural grass fields and synthetic turf systems. It is well established and accepted by the Owner that Owner’s maintenance plays an important role in the subsequent Gmax test values for installed, infilled, synthetic turf systems of the type specified herein in conjunction with the design characteristics of the manufactured product and installation process. As such, the synthetic turf system installation, designed for multiple sport usage including varsity football practices and games, will be periodically tested for shock attenuation (Gmax) properties in accordance with ASTM F 1936 and F 355, Method A, per frequency intervals and Gmax standards provided herein.; (b) Test Locations: i. The installed system will be tested for Gmax at the locations defined in ASTM F 1936. All test locations will be offset approximately 12 inches from any fabric seam, and all subsequent retesting will be performed at the exact same locations as previous test locations for comparisons.; (c) Test Frequency and Gmax Compliance Standards
