Specifications include, but are not limited to: Remove entire area of the safety surface to concrete base, prepare base and install new safety surfacing to comply with ASTM standards on the Kindergarten and Intermediate and Primary East and Primary South Playground Units. Demolish all playground equipment in coordination with CCSD Safety and Equipment Unit to salvage reusable parts. Excavate the subbase materials as needed to adequately grade subbase material to align with the existing concrete curbing on all units requiring replacement surfacing so as to achieve the proper gradients for the new surfacing. Install concrete base properly so to allow complete adhesion of the safety surface on all units requiring replacement surfacing. Prepare for, provide and install new playground equipment on the Kindergarten (to include Pre-Kindergarten Equipment),Intermediate and Primary Playground Units. Install signs in the adjacent asphalt surface at each playground unit – coordinate precise location.
