ARTIFICIAL TURF GROOMING/MAINTENANCE 2
Turf field maintenance/grooming contractor shall make at least three grooming visits each year in accordance with Task Maintenance Schedule included in these specifications, at intervals approved by City in spring, summer and fall, after the initial site meeting with City and turf manufacturer. Grooming visits shall be scheduled with the Danehy Park Superintendent to inspect and document condition of the synthetic turf surfacing system including turf fibers, infill materials, and depth of infill. Turf field maintenance/grooming contractor shall also be responsible for addition of infill to any areas of field or entire field, to maintain minimum 1 ¾-2-inch depth. Field maintenance and grooming shall take place as specified herein. The Maintenance Service Program shall be performed by personnel fully licensed, insured and prequalified by synthetic turf manufacturer. Each Program shall include, but not necessarily be limited to, the following components to be performed at each visit:
During each grooming visit create a written visual inspection report consisting of an overall field analysis including an evaluation of key areas around the field to ensure areas are within acceptable standards. Note date and time of visit, contact information, and any findings on a manufacturer’s approved check sheet, including but not necessarily limited to: seam condition, infill migration, wear spots, drainage concerns, paint condition, curbing condition, UV degradation, evidence of vandalism, fiber fibrillation analysis, and any inlays built into the field. Closely examine soccer goal mouths, penalty kick dots, corner kick areas, mid field and sideline areas. Mark low spots needing additional infill. Furnish 2 copies to the City.
Sweep entire surface with a specially designed hydraulic sweeper attached to a 3 point hitch on a tractor to remove debris including but not limited to, leaves, hair, loose gum, cigarette butts, litter and debris, etc. from the field. Sweeper shall have a hopper into which the debris is projected. Install a fine wire mesh in the bottom of the hopper to allow the infill to fall through the mesh and remain on the field. The mesh shall have openings no larger than 1/8" to 1/4". Contact the synthetic turf surfacing manufacturer for distributors of acceptable sweepers. Remove and dispose of sweepings.
Add additional infill material to spots marked as being low from the initial field analysis to maintain two-inch infill depth. Use a top dresser with a "drop" discharge mechanism to distribute the necessary quantity of infill evenly over the affected area. Groom the infill into the turf by lightly agitating the fibers to get the infill to "drop" into the turf. Do not over groom or the infill will come out of the turf. Repeat grooming until turf is properly infilled. Once the turf has been infilled to the level recommended by the synthetic turf surfacing manufacturer, gently agitate the area one last time to get the infill to completely "drop" from the fibers. This shall only be done when turf fibers and infill are dry. After litter and debris is removed, and low spots are filled, groom field to agitate infill materials and raise fibers to a vertical position. Pull a manufacturer’s approved groomer behind a tractor in various directions around the field. If directed by the City, turf field maintenance/grooming contractor shall groom small areas of the field, as required, to move displaced infill back into place. A medium stiff brush bristle, as approved by the synthetic turf surfacing manufacturer, shall be used to groom the surface. With just enough pressure to adequately stir up the fibers, groom the surface to displace the infill back to where it is missing. Grooming the surface in both directions can help to re-level the infill if it has been displaced.
If outdoor atmosphere is dry or hot, drag field with drag mat to remove static charge. Static charge is present if static is visible on tractor tires after sweeping and grooming.
Field line painting will be by City (or separate contractor), but contractor and turf field grooming/maintenance contractor shall be responsible for coordinating grooming activities with field line painting.
Schedule first visit as shown on task maintenance schedule and approved by Danehy Park Superintendent. Fields 1,2,3 & 4 will require at least 3 and up to 5 grooming per year.
manufacturer’s representative is available at all time to answer questions and demonstrate maintenance procedures while on site.
Issue written maintenance report two (2) copies to Owner and the City’s environmental specialist after each visit. Payment will not be made for any grooming until grooming report is submitted.
