Schedule of
rates or list of rates of different items is made after the analysis of rates
of these items. This type of document is called the schedule of rates or S.O.R.
It is made by large concerns or public bodies. It becomes very helpful,
particularly in deciding the rate of an extra item, carried out by the
contractor. A schedule of rates for each kind of work is maintained by the
various engineering department or authorized organizations in the form of a
printed books called "Schedule of
Rate Books".
1. Schedule
of rates includes the rate of wages of labour, rate per unit of different items
of work and materials, and rates of transport and it also consists of groups of
items like excavation items, demolishing items, brickwork items concrete items,
etc.
2. As the
rates of items noted in the schedule of rates are likely to vary.
3. The
schedule of rates is regularly updated, generally after three years.
4. In the
schedule required analysis of the rates for the different conditions should be
provided.
5. The
schedule of rate is made on the basis of analysis of rates.
Generally, transport of materials up to distance of 5 miles (8 km)
is added in the rates.

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 ...
