Q. Prepare Rate analysis for a PCC work (1:3:6). Sol n .:- Given: - Concrete grade = M10 (1:3:6) Take = 10m 3 volume for PCC Add 52% extra for voids to get dry vol m . of Concrete. Volume of dry concrete = 1.52×10 = 15.2 m 3 Quantity of cement = (15.2/(1+3+6) ) ×1 ...
In this
method, the longer walls in a building are taken as long walls & calculated
from out-to-out & the partition
or shorter walls which make the right angle with the long walls are taken as
short walls and are calculated from in-to-in
for a particular layer of work. To calculate the quantities multiplying the
lengths of long & short walls by the breadth & the height of wall. These
lengths of long and short walls differ in each layer of footing.
PROCEDURE:-
1. Prepare the foundation plan
shown in fig. with all dimensions. Centre-to-Centre dimensions are taken out by
adding half width of each cross wall to inner dimension of room.
2. Now divide the walls into two
groups. In plan, walls in the horizontal direction are called Long walls &
vertical direction walls are called Short walls & Vice-Versa.
3. Measure the length of long
wall for an item by using formula-
Length
of Long wall for an item = length of long wall C/C + One width of an item (Half
width of each end)
4. Measure the length of short
wall for an item by using formula-
Length
of Short wall for an item = length of short wall C/C - One width of an item
(Half width of each end)
5. Multiply no., length, width,
& depth/height to get quantity of an item.

The different types of plan are explained below- (i) Site plan (ii) Layout plan (iii) Index plan (iv) Key plan (v) Services plan. 1. Site Plan - Site plan is a general layout of the site drawn as a line diagram to a small scale along with the surrounding plots of land & adjoining roads to place the site and to represented the means of access. The orientation of the building along with the North direction is represented in the site plan. In site plan the position of sewer lines & water etc., may also be provided. Site plans are drawn to a scale of 1 cm = 5 m to 1 cm = 10 m in the working drawings. 2. Layout Plan - For a project consisting of a number of various structures, a layout i.e. the comparative positions of all the various units to be constructed land is represented to a scale generally 1 cm = 10 m to 1 cm = 20 m and is called a layout plan. This helps to form a general idea and ...
Q. Prepare Rate analysis for a RCC work with M15 grade of Concrete. Sol n .:- Given: - Concrete grade = M15 (1:2:4) Take = 10m 3 volume for RCC Add 52% extra for voids to get dry vol m . Of Concrete. Volume of dry concrete = 1.52×10 = 15.2 m 3 Quantity of cement = (15.2/(1+2+4) ) ×1 ...
