Round 1 Bowling and Amusement 12/09/2024 Paradigm Design <br />Main Place Mall Expansion Grand Rapids, MI <br />Santa Ana, California <br />Project #2309147GR <br />G.Install seismic-restraint devices using methods approved by an agency acceptable to authorities <br />having jurisdiction that provides required submittals for component. <br />H.Install bushing assemblies for anchor bolts for floor-mounted equipment, arranged to provide <br />resilient media between anchor bolt and mounting hole in concrete base. <br />I.Install bushing assemblies for mounting bolts for wall-mounted equipment, arranged to provide <br />resilient media where equipment or equipment-mounting channels are attached to wall. <br />J.Attachment to Structure: If specific attachment is not indicated, anchor bracing to structure at <br />flanges of beams, at upper truss chords of bar joists, or at concrete members. <br />K.Drilled-in Anchors: <br />1.Identify position of reinforcing steel and other embedded items prior to drilling holes for <br />anchors. Do not damage existing reinforcing or embedded items during coring or drilling. <br />Notify the structural engineer if reinforcing steel or other embedded items are <br />encountered during drilling. Locate and avoid prestressed tendons, electrical and <br />telecommunications conduit, and gas lines. <br />2.Do not drill holes in concrete or masonry until concrete, mortar, or grout has achieved <br />full design strength. <br />3.Wedge Anchors: Protect threads from damage during anchor installation. Heavy-duty <br />sleeve anchors shall be installed with sleeve fully engaged in the structural element to <br />which anchor is to be fastened. <br />4.Adhesive Anchors: Clean holes to remove loose material and drilling dust prior to <br />installation of adhesive. Place adhesive in holes proceeding from the bottom of the hole <br />and progressing toward the surface in such a manner as to avoid introduction of air <br />pockets in the adhesive. <br />5.Set anchors to manufacturer's recommended torque, using a torque wrench. <br />6.Install zinc-coated steel anchors for interior and stainless-steel anchors for exterior <br />applications. <br />3.4 ACCOMMODATION OF DIFFERENTIAL SEISMIC MOTION <br />A.Install flexible connections in piping where they cross seismic joints, where adjacent sections or <br />branches are supported by different structural elements, and where the connections terminate <br />with connection to equipment that is anchored to a different structural element from the one <br />supporting the connections as they approach equipment. <br />3.5 ADJUSTING <br />A.Adjust isolators after piping system is at operating weight. <br />B.Adjust limit stops on restrained-spring isolators to mount equipment at normal operating height. <br />After equipment installation is complete, adjust limit stops so they are out of contact during <br />normal operation.
