# How work out the concrete quantity of beams for water tank, head & lift room

This civil engineering video tutorial provides the detail guidelines to work out the concrete quantity for beams used in water tank, headroom and lift room.

The drawings for beams are created in AutoCAD and the entire calculation is done in excel sheet.

Calculation of concrete quantity for head room beam :-

As for example, the length of beam is given as 4.77m and its size is 0.23m x 0.30m and number of beam is 1.

So, the quantity of beam will be number x length x size = 1 x 4.77 x 0.23 x 0.30 = 0.33 cubic meter.

Calculation of concrete quantity for floor beams of lift :-

As for example, the length of beam is given as 2.15m and its size is 0.23m x 0.30m and numbers of beams are 4.

So, the quantity of beam will be number x length x size = 4 x 2.15 x 0.23 x 0.30 = 0.59 cubic meter.

In order to obtain final quantity, sums up all the quantities of beams.

The above process can be followed to work out quantity of concrete for beams for all the floors.

To learn how the calculation can be done in excel with formula, go through the following video tutorial.
