Specifications include, but are not limited to: The City intends to use this agreement for the following: A. Complete resurfacing of resilient surfaces for playgrounds, adult fitness, and designated areas for the City and County of Honolulu. B. Repairs to resilient surfaces. C. Testing of resilient surfaces. D. Ensuring that all resilient surfaces are in compliance with Americans with Disabilities Act (ADA) and safety requirements. The Contractor shall furnish and pay for all necessary labor, materials, tools, equipment, and work necessary to provide pour-in-place or re-top pour-in-place resilient play surfacing at various City parks as specified herein for the Department of Parks and Recreation (DPR) in accordance with all Federal, State, City laws, ordinances, rules, regulations, and guidelines. A. Surfacing Materials. The manufacturer of the poured-in-place (PIP) rubber safety resilient surfacing described herein shall be “SofTurf” as manufactured by IPR Inc; “UltraFlexTop” as manufactured by FlexGround; “Pebbleflex” as manufactured by Landscape Structures; “SpectraPour” as manufactured by SpectraTurf; “PlayBound” as manufactured by SurfaceAmerica; or approved substitute (in accordance with Section 2.18 Request for Substitutions of General Instructions to Offerors, dated 02/09/2017). The PIP safety surfacing system should be in accordance with the following: 1. A dual durometer PIP system with a wearing layer upper membrane. 2. The finished surface shall be porous. 3. Primer shall be a low-viscosity 100% solids urethane primer/sealer with penetrating abilities. 4. The cushion layer should be a mixture of recycled styrene butadiene rubber (SBR) rubber buffings, strands may vary from 0.5 mm-2.0 mm in thickness by 3.0 mm-20 mm in length, mixed with a 100% solids moisture cured methylene diphenyl diisocyanate (MDI) Polyurethane binder or aliphatic (100 pounds of SBR rubber buffings to 12 pounds of binder) installed at the appropriate thickness. The cushion layer should be porous. 5. The wearing surface should be composed of 0.5 mm-1.5 mm thermoplastic vulcanized (TPV) virgin colored rubber mixed with aliphatic binder (110 pounds of TPV to 24.2 pounds of binder), and applied to a minimum thickness of a half (1/2) inch over the cushion layer. 6. The TPV rubber granules (0.5 mm-1.5 mm) need to be compliant with ASTM F1292 and have an International Play Equipment Manufacturers Association (IPEMA) Certification specific to PIP safety surfacing. B. Cushion Layer. The components of the PIP safety surfacing shall be in compliance with the manufacturer’s instructions. The cushion layer should be thoroughly mixed with recycled SBR rubber buffings, strands may vary from 0.5 mm-2.0 mm in thickness by 3.0 mm-20 mm in length, and the MDI moisture cure polyurethane binder at a rate of 12% of the total weight of buffing material so that binder is evenly dispersed into the rubber base. The cushion layer mix should then be spread and troweled at a minimum of 1 inch thickness over existing rubber. Where rubber has been excavated, new buffing material shall be troweled in and terminated at a depth of a half (1/2) inch from the top of the connecting surface (ADA transition) or a half (1/2) inch back from perimeter keyway. Must allow to cure for 24 hours. C. Wear Course Layer (top layer). The wear course layer should be composed of 0.5 mm-1.5 mm TPV or approved substitute, virgin colored rubber mixed with aliphatic binder at a rate of 22% of the total weight of TPV materials so the granules are covered thoroughly and evenly. The wear course layer mix should be spread and troweled over cushion layer to a minimum thickness of a half (1/2) inch and must terminate flush with connecting surface or into existing keyway. Where seams are required due to color change, a step configuration will be constructed to maintain wear surface integrity. The finished texture should be slip resistant, smooth and even. Installers shall work to minimize excessive adhesive on adjacent surfaces or play equipment. Spills of excess adhesive shall be promptly cleaned. The PIP surface should be allowed to cure for 24-72 hours or until dry to the touch.
