∑B.S. – ∑F.S. = Last R.L. – First R.L. = ∑Rise – ∑Fall

A(B.S.) = 1.250 -> B(F.S.) = 2.250 There is a fall from A to B

Difference in R.L. = Difference in staff reading

Note: There is no entry in the first row of rise and fall column.

Amount of fall = Following staff reading – Preceeding staff reading

Rise = B.S. – F.S.

R.L. = R.L.(previous) – Fall

R.L. = R.L.(Previous) + Rise

(Previous) I.S. – I.S. = Rise/Fall

H.I. = R.L. + B.S.

(Previous) H.I. = R.L. + I.S.

I.S. – Fall = B.S.

Collimation plane – R.L. = B.S.

$Gradient = {\text"First R.L. – Last R.L."}/{\text"Total Distance"}$

$Gradient = {\text"Total distance"}/{\text"Total Fall"}$

Actual ground coverage = [l – (2 x length of margin)] x [b – (2 x breadth)]

F.S.I consumed = (Actual ground coverage x no. of floors)/(Actual plot area)

Total built up area = Plot area x F.S.I. permissible

Area can be constructed on second floor = Total built up area – (area occupied by 1st floor + area occupied by 2nd floor)
