Project work is defined by the Contract Documents (i.e. construction drawings and specifications) and consists of, but is not limited to, the following items: The project consists of converting the portion of existing natural turf shown in the construction drawings. The area is within the limits of the baseball and perimeter fences including underground drainage, structural base, shock pad, synthetic turf with associated nonfill synthetic turf. The new 8" perforated, corrugated, HDPE pipes in stone filled trench are to be installed next to the inside of the baseball perimeter fence. · Locate and secure clearance for all project specific utilities. It is solely the responsibility of the CONTRACTOR to repair damaged utilities. · The elevations for the athletic fields are shown on the attached drawings. The grading plan accompanying these drawings shall be followed to ensure positive drainage flow. The CONTRACTOR shall bear the responsibility of verifying these elevations. · All surveying for field placement and layout is the responsibility of the CONTRACTOR. · CONTRACTOR shall remove vegetative layer as per construction drawings and specifications and specifications. · CONTRACTOR shall remove and dispose of any other material deemed undesirable. (i.e. existing natural grass on playing field will be removed by the CONTRACTOR.) CONTRACTOR shall remove all other material deemed undesirable as per construction drawings and specifications and specifications. · Excavate to depth required to accommodate required cross-section, slope and finished grades. · Prior to installing specified structural base, contour, slope, rough grade, and compact sub-base, within limits of area field shown in construction plans to specified grades, as per construction drawings and specifications. · Install a poured in place structural base with minimum 3,000 psi concrete poured into a minimum 40 millimeter deep structural grid as detailed in Section 025030 - Nonfill Synthetic Turf System specification. · Install poured in place reinforced concrete perimeter turf anchor curbing with pressure treated wood nailer board at locations shown and detailed in the construction drawings and specifications. The pressure treated nailer board must rated as UC4B - approved for heavy duty ground contact. The top of the nailer board must match finish grade of the concrete base. · On areas that do not have a concrete curb, the nailer board will be anchored with stakes, approved for ground contact, as per the Edge Detail ~ Turf Installation with Transition to Natural Grass shown in the construction drawings and specifications. · Home plate to be installed and anchored into the structural base of the field with metal ground anchor(s). · Install poured in place concrete pitcher's mound in accordance with the following NCAA regulations: · The top of the pitcher's rubber must be 10 inches above the top surface of home plate. The 10-inch height can be measured easily by the use of a line level. There should be a gradual slope of 1 inch per foot from a point 6 inches in front of the pitcher's rubber to a point 6 feet toward home plate. From this point, the mound should slope and blend into the grade of the rest of the playing surface. · The top of the pitcher's mound should be level with the top of the pitcher's rubber, extending from the point 6 inches in front of the pitcher's rubber to 22 inches behind the pitcher's rubber and 18 inches from each end of the pitcher's rubber. This gives a level area 5 feet wide and 34 inches deep that includes the 6-inch width of the pitcher's rubber. · Batters boxes, game catchers box, home and visitor bullpen pitchers landing areas, and home and visitor bull pen catchers boxes must be removable Velcro backed turf in order to be replaced as needed due to wear. See turf submittals for exact locations of Velcro backed turf. · Install double base anchor for baseball first base. · Install the perimeter collector trenches and tie in as shown on the construction drawings and specifications. · Furnish and install a shock pad/drainage blanket system that meets the performance requirements of the preapproved products detailed below. · Install nonfill synthetic turf system, tufted to a maximum 1.25-inch height, having 100% polyethylene fibers with a dimensionally stable primary backing that meets the performance requirement as detailed herein this bid package. · Install all tufted and inlaid lines and markings as shown in the construction drawings and specifications. · Install natural, non-silica, and non-organic Cooling Additivel. Infuse infill mixture into artificial turf in multiple applications. · Clean site per owner's instructions and dispose of any unwanted materials. · Repair any damage to areas, including parking lots, staging areas, bullpens, outfield grass or utility lines, or other that may have occurred and restore site to pre-project condition.
