1.Bottom Of Base plate elevation to be finalized from design drawings
2.If we use plate washers ,We need to follow over sized holes in base plate i.e
for example: if we use 3/4" Ø anchor rod,Hole dia should be 1 5/16"Ø.
3.Plate washers sizes should be followed for AISC 14.2 table.
for 3/4"Ø anchor rod , we will follow plate washer size as 1/4"X2X0'-2".
4.Plate washers is used to cover the over sized holes.
5.If design drawing does not furnish levelling method pattern then we need send to
rfi on levelling method,Mostly we will use levelling nut or levelling plate arrangement.
we will use levelling plate thickness as 1/4" and we will match plate parameters to base plate size.
6. Template : Template is used to match accurate position of anchor rods,Generally
Template thickness we will follow as 1/8" and we will match length and width as base plate size.
7.Grout hole: If smaller side dimension of the base plate exceeds approximately 2'-0 then we will provide grout hole in base plate.
8.column schedule to be referred properly ,So that we will exact base plate sizes and anchor rod dia.
9.if design drawing does not provide embedment then we need to calculate embedment
by using formula i.e 12 X Diameter of anchor rod.
if we use 3/4"Ø then embedment is 9".
10.If design drawing does not provide projection then we need to calculate projection by
using formula i.e Grout thickness + base plate thickeness + 2 times of anchor rod dia
+washer thickness + nut thickness.
11.We need to identify footing depths properly because we should maintain 3"clearence
between bottom of anchor rod and bottom of footing.
some times in order to maintain footing depth ,We need to deviate embedment values
and also we need to ask question for confirmation.
