2) Finding Out Unit Rate For Various Items of Work

The unit rate for a different item of construction is given in SOR (Schedule of Rate). SOR is a document that has a list of various items of work.

It helps in the preparation of estimates and also serves as a guide in setting rates in connection with contract agreements, a schedule of rates for all items of work is maintained in the form of printed books as a Schedule of Rate(SOR).

The schedule of rates consists of a group of items such as excavation items, concrete items, masonry items, demolition items, plumbing items, electrification items, etc.

As the rate of items mentioned in the schedule of rates is likely to vary, the SOR is periodically revised, usually after 3 years.

The Public Works Department (CPWD), a premier construction organization of the government of India, maintains a printed schedule of rate books for various items of work, and an estimate is prepared with these rates.

This SOR contains a rate of about 2500 to 3000 items. In the CPWD SOR the items are covered under different subheads like building work, road work, water supply, sanitary items, etc.

The rate of the finished item is worked out by the analysis of the rate with the standard requirement of materials, labor, equipment, and necessary sundries like water charges, contractorsprofit, etc.
