Dear Sirs,
As per IS 1200 Part 8 - measurement conditions, the structural steel elements shall be measured as below;
4.3 Unless otherwise specified, mass of cleats,
brackets, packing pieces, bolts, nuts, washers,
distance pieces, separators, diaphragm, gussets
( taking overall rectangular dimensions), fish
plates, etc, shall be added to the weight of
respective ite D1S. In riveted work, allowance i~
to be made for mass of rivet heads ( see 3.1 ).
No deduction shall be made for rivet or bolt
holes ( excluding holes for anchor or holding
down bolts ). Deduction in case of rivet or bolt
hole shall, however, be made if its area exceeds
0·02 rol and for notch if its area exceeds 0,05 mt .
For other type of openings like holes for service
pipe etc, deduction shall be made if its area
exceeds 0'1 mi.
However there are few things are not explained in detail hence the interpretation can different between anyone.
For plates, if the notch area is less than 0.05sqm the weight of notch portion can included to the element weight and the same to be paid by the buyer. If the notch area is greater than 0.05sqm then the weight of notch portion shall be considered or claimed.
Is that the same condition is applicable for rolled sections? As my understanding the same condition is applicable is sections as well. Please clarify. |
