Scope of Work) <br />Installation and Removal. The screens are bolted to the concrete walls and soffit of the <br />catch basin. No part of the screen or mechanism shall interfere with the removal of any <br />existing gratings. <br />Standard Design Elements (ARS): 12 gauge stainless steel screen with 3/4 -inch diameter <br />holes with at total open area of not less than 50%. Locking mechanism prevents the brushes <br />of street sweeping equipment from opening the screen while sweeping. The locking <br />mechanism also prevents tampering of the units. The West Coast Storm Screen is specifically <br />designed to open automatically by force of water during a rain event. The locking mechanism <br />operates on horizontal pressure, not vertical pressure; this design keeps the units free of <br />debris and sediment. The CAM gear design of the locking mechanism means no springs that <br />break, no pulley or counter weights that require frequent maintenance, adjustment, or <br />replacement. The ARS design has few moving parts, a simpler design is a more efficient, <br />ease of maintenance, and working design. The gate closes upon water receding, no drainage <br />of weeping buckets or cleaning out of operation components are needed. <br />Below is an example of an installation in Coral Gables, Florida demonstrating an area where <br />install conditions were good. <br />Page 6 of 45 <br />654 South Lincoln Avenue, San Bernardino, CA 92408 - Telephone 909.890.5700 Facsimile 909.890.5988 <br />California General A/HAZ Contractor License Number: 888152 <br />25C-27
