Standard Guide for In-ground Concrete Skatepark
ABSTRACT
This guide covers safety and performance guidelines pertaining to in-ground skatepark facilities built primarily out of concrete and other designed materials. Any concrete materials and other designed materials intended to be used in the performance of the sports including skateboarding, inline skating and BMX biking shall be discussed. Other materials present in skatepark facilities include steel reinforcing and synthetic fibers. Physical properties such as concrete finish, surface flatness, and levelness shall be considered. In addition, expansion joints, filled control joints, and tooled control joints shall be discussed. Expansion joints should be placed where they are least likely to interfere with a wheel. Careful consideration to expansion joints location must be given, using the flow of skaters as critical design criteria. Size of control joint is not important. It must be a rigid control joint filler, which must be flush with the skating surface and close the joint completely. Also, joints should be placed where they are least likely to interfere with skate wheels, and a cut control joint is not possible. The placement of concrete on sloped radii or any areas incorporating a change in elevation is critical to the stability of the exposed steel material or concrete coping. The difficulty of achieving proper consolidation around the steel material and their reinforced attachments through the use of standard air removal consolidation techniques can lead to slumping and the creation of an air pocket around the steel material, which may not be visible during construction and may result in concrete failure on the riding surface. Skatepark signage, free standing or fixed fence, shall be provided and shall indicate the following: adult supervision of minors is or is not present; owner-operator emergency telephone numbers; emergency telephone numbers for medical, ambulance, and police; applicable regulations regarding the use of safety gear; presence of inherent risk in the participitation of skatepark activities; and drunk or users under the influence of drugs shall not participate in any skatepark activities.
SCOPE
1.1 This guide covers safety and performance guidelines pertaining to in-ground skatepark facilities built primarily out of concrete and other designed materials. This guide pertains to any concrete materials and other designed materials intended to be used in the performance of the sports including skateboarding, inline skating and BMX biking. Items such as fencing, lighting, and operational structures are not intended to be a part of this guide.
1.2 Tolerance: General Measures, Tolerances, and Conversions—General dimensional tolerances for this guide (unless otherwise noted) follow. These tolerances still apply to a dimension even when terms like greater than, less than, minimum, or maximum are used. Dimension Tolerance X in. or ft±0.5 in. X.X in.±0.05 in. X.XX in.±0.005 in.
1.3 The values stated in inch-pound units are to be regarded as standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
