Hello dear viewers in this video we are going to calculate the various quantities of slab such as concrete work and steel reinforcement provided in slab.While constructing the house or any structure before that we have to calculate the various quantities of material which is required to construction.A
RULES FOR MEASUREMENT :
The rules for measurement of each item are invariably described in IS-
1200. However some of the general rules are listed below.
1. Measurement shall be made for finished item of work and description of
each item shall include materials, transport, labour, fabrication tools and
plant and all types of overheads for finishing the work in required shape,
size and specification.
2. In booking, the order shall be in sequence of length, breadth and height or
thickness.
3. All works shall be measured subject to the following tolerances.
i) Linear measurement shall be measured to the nearest 0.01m.
ii) Areas shall be measured to the nearest 0.01 sq.m
iii) Cubic contents shall be worked-out to the nearest 0.01 cum
4. Same type of work under different conditions and nature shall be measured
separately under separate items.
5. The bill of quantities shall fully describe the materials, proportions,
workmanships and accurately represent the work to be executed.
6. In case of masonary (stone or brick) or structural concrete, the categories
shall be measured separately and the heights shall be described:
a) from foundation to plinth level
b) from plinth level to First floor level
c) from Fist floor to Second floor level and so on.
Details of measurements and calculation of quantities:
The complete work is divided into various items of work such as earth
work concreting, brick work, R.C.C. Plastering etc., The details of measurements
are taken from drawings and entered in respective columns of prescribed
proforma. the quantities are calculated by multiplying the values that are in numbers
column to Depth column as shown below:

ii) Abstract of Estimated Cost :
The cost of each item of work is worked out from the quantities that
already computed in the detals measurement form at workable rate. But the
total cost is worked out in the prescribed form is known as abstract of estimated
form. 4%of estimated Cost is allowed for Petty Supervision, contingencies and
Unforeseen items.
