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 />C.Fiberglass Pipe Hanger Installation: Comply with applicable portions of MSS SP-69 and <br />MSS SP-89. Install hangers and attachments as required to properly support piping from <br />building structure. <br />D.Metal Framing System Installation: Arrange for grouping of parallel runs of piping and support <br />together on field-assembled metal framing systems. <br />E.Fiberglass Strut System Installation: Arrange for grouping of parallel runs of piping and <br />support together on field-assembled fiberglass struts. <br />F.Fastener System Installation: <br />1.Install powder-actuated fasteners for use in lightweight concrete or concrete slabs less <br />than 4 inches thick in concrete after concrete is placed and completely cured. Use <br />operators that are licensed by powder-actuated tool manufacturer. Install fasteners <br />according to powder-actuated tool manufacturer's operating manual. <br />2.Install mechanical-expansion anchors in concrete after concrete is placed and completely <br />cured. Install fasteners according to manufacturer's written instructions. <br />G.Install hangers and supports complete with necessary inserts, bolts, rods, nuts, washers, and <br />other accessories. <br />H.Equipment Support Installation: Fabricate from welded-structural-steel shapes. <br />I.Install hangers and supports to allow controlled thermal and seismic movement of piping <br />systems, to permit freedom of movement between pipe anchors, and to facilitate action of <br />expansion joints, expansion loops, expansion bends, and similar units. <br />J.Install lateral bracing with pipe hangers and supports to prevent swaying. <br />K.Install building attachments within concrete slabs or attach to structural steel. Install additional <br />attachments at concentrated loads, including valves, flanges, and strainers, NPS 2-1/2 and larger <br />and at changes in direction of piping. Install concrete inserts before concrete is placed; fasten <br />inserts to forms and install reinforcing bars through openings at top of inserts. <br />L.Load Distribution: Install hangers and supports so piping live and dead loads and stresses from <br />movement will not be transmitted to connected equipment. <br />M.Pipe Slopes: Install hangers and supports to provide indicated pipe slopes and so maximum <br />pipe deflections allowed by ASME B31.1 (for power piping) and ASME B31.9 (for building <br />services piping) are not exceeded. <br />N.Insulated Piping: Comply with the following: <br />1.Attach clamps and spacers to piping. <br />a.Piping Operating above Ambient Air Temperature: Clamp may project through <br />insulation.
