Hard Hat Cafe - Sign (Pole & Wall)
Rte: Sian Installation for Hard Hat Grill
t>
Dear Dave,
The design calculations for the :Sign at hard hat grill are attached. This analysis
Shaws the estimatin� program under estimated the size of the si�r�p€�st and over pressures
the sail_ The mass foaling is adequate for over turning but the reinforcement does not meet
requiremerits for minirnum reinforcement ratios.
The following modifications to the design are recommended to bring the design into UBS
cid requirements.
1.) The posh column should be made Pram one of the alternate member listed in feast cost
order.
12" diameter standard pipe
I 0'' extra stxoncy pipe
TS 1 0x 8x3/8
2.} The lenoth of the footing should be increased to 9'-6 long yielding a footing 9'-b hong x
6"-0 v.�i��b-N17 �'-� deep oxze���:ed vwithions axis perpendicular �o the ��ng face.
91;
3.} The reinforcincy steel needs to be4,8 bar at I?" each way tai aiid bottom or #6 bar at 7
'l�" each way top and bottom.
The sign connection to the post is not detailed so I am heaving the detail to sign builders.
Should any illin� arise that requires my attention please call.

Sincere,
