Our response appears in bold. <br /> 1. On Details 6/53.1 and 7/S3.1, it appears that the top of the handrail exceeds the maximum height of 38" <br /> from the top of the stair tread per IBC 1014.2. If the smaller rail beneath the top rail is intended to be the <br /> handrail,these handrails should be continuous per IBC 1014.4. Please revise geometry as required.As part of <br /> this continuity requirement for handrails,clearances and projections per IBC 1014.7 and IBC 1014.8, <br /> respectively should be reviewed for compliance should the handrail geometry change. <br /> A handrail was added beside the existing intermediate rail. Refer to revised detail 6/S3.1. <br /> 2. On Detail 2/S2.1,the handrails appear to be missing their extensions per IBC 2015 1014.6 at the top and <br /> bottom of the stairs. Please revise handrails as required. <br /> The extensions have been added to the handrail at the top and bottom of the stair. Refer to revised detail <br /> 2/52.1. <br /> 3. On Detail 7/S3.1, it appears that the intermediate 0.75" diameter STD Pipe vertical posts that comprise the <br /> guardrails exceed the 4" sphere threshold per NBC 1015.4. Please revise geometry as required. <br /> The%"diameter pipe has an outer diameter of 1.05"and therefore the opening is 3.95". <br /> 4. On Detail 3/S3.1, it appears that the 4" max spacing would permit the passage of a 4"sphere per IBC <br /> 1011.5.5.3 Exception 1. Please revise as required. <br /> The%"diameter pipe has an outer diameter of 1.05"and therefore the opening is 3.95". <br /> 250 4th Avenue South,Suite 200 <br /> Edmonds,WA 98020 <br /> ph.425.778.8500 I f.425.778.5536 <br /> www.cgengineering.com <br />
