APPROACH/METHODOLOGY I Q ® pipe shall be a solid schedule 40 PVC pipe. The PVC =0 �� ; m pipe shall then connect to a local water management , system (NIC). , • Installation of a tiled (herringbone pattern) drain field, ' • consisting of multiple rows of perforated flat panel drain pipe that is connected directly to the perforated pipe in jj = a - the perimeter trenches. —. -�_= `-- .- • Installation of aggregate materials in a manner and type, �y as necessary to meet specified performance requirement ' � ` - �- of the stone base, and to achieve the specified finish �� vr grade. ... . ..... _.— . . _ - • . : - , • Installation of the synthetic grass tufted to a 2"pile height, having 240-micron (min), 100% polyethylene fibers with a dimensionally stable primary backing that meets the — :;, ;ii ` performance requirement as delineated herein. _}, - A f L r. + .>:x.� s .K • Installation of all in-laid lines (painted if required by ; :<•._-:" _ - - __ owner), markings and numbers. • Installation of a resilient crumb rubber/silica sand infill _ , ' system, per the specifications of the synthetic grass - • : ...,44.-1.'t_ ; contractor. • All necessary inspections and testing that each component in the entire system has been properly ® prepared and/or installed, including: excavation, perimeter curbing & nailers, collector drains, stone sub-base, finished stone base, sloping, synthetic turf and G-max testing. • BASE CONSTRUCTION: SUB BASE — After removal of all organic material and debris from the playing field area, the area is to be cut down no less than 6 inches from the top of the proposed finished height of the base. The sub base shall be roll tested to find "soft spots", compacted and rolled to as close as possible to a 95% proctor density and be sloped 0.5% - 1% from the centerline "ridge" of the playing field towards both sidelines. NOTE: The ridge on baseball and softball fields shall run from home plate, through second base and out to centerfield. CONCRETE CURBING / NAILER — A trench shall be excavated around the perimeter of the playing field to accommodate a wide x 1 2" deep concrete curb. The concrete shall be 3500 psi minimum, to a uniform specified grade. After a minimum 2-day cure time, a pressure treated (PT) nailer board shall be secured to the concrete curb using mechanical fasteners (Ramset, or equivalent). The fasteners shall be spaced on 24" centers. The fasteners nearest to the ends of the nailers shall be no more than 6" from the end. PERIMETER TRENCH (Collector Drain) —The perimeter trench shall be installed around the field, adjacent to the inside edge of the concrete curb. The trench shall be approximately 2' wide at the top, tapering down to an adequate size that will accommodate a 010" (min) pipe. The depth of the trench shall be sufficient to allow the pipe to be properly sloped (0.25% minimum) to ensure a positive outflow of water. ® Recreational Design & Construction, Inc.
