The following assumptions are made in generating Material take-off:
a. Column:
Column length is calculated as per the length available from the analysis file. No deductions are made for calculating the length of the column.
b. Beam supported on the column:
Beam length is calculated as per the c/c distance between support with a deduction of 10mm on either side for the connection.
c. Beam supported on the beam:
Beam length is calculated by deducting half the thickness of the web in the case the supporting member is I-shaped. If the supporting member is RHS or SHS, half the dimension plus a gap of 10mm is deducted.
d. Elevation Bracing:
Elevation Bracing member length is calculated as drawn in the section drawings.
e. Plan Bracing:
Plan Bracing member length is calculated as drawn in the section drawings
2. Material Take-off for plan and section drawing
Material take-off is also available for selected plans and section drawings. The length of the members is calculated with the following assumptions,
Column length is calculated as per the floor level available ( Y-coordinates). No deductions are made for calculating the length of the column.
b. Beam Supported on the column :
Beam length is calculated by deducting half the dimension of the supporting member. In case of the beam is supported on the I-shaped column, the outermost rectangle of the column is considered for the deduction.
If the beam is released at the ends (Major moment), a drawing is generated keeping the gap of 10mm between the beam and column outer extent as a shear connection.
If the beam is not released, a drawing is generated keeping the no gap between the beam and column outer extent as a moment connection.
In both the above cases, Length is calculated as follows,
Example: beam length is 5000mm and the depth of the column on which the beam is resting on both ends is 300mm.
Beam length = 5000 – 2 x (300/2)
= 4700 mm
Plan Bracing member length is calculated as drawn in the section drawings.
