Interpretation of Quantities(BOQ)

The Bill of Quantities (BOQ) describes various items of work and the quantity of work under each item that is required to be  executed for completing the job. While quoting, the Contractor is expected to have read the specifications in working out his unit rates. Sometimes, this is also called Schedule of Quantities (SOQ). 

Frequently, the specifications are not studied very carefully and hence some very important aspects may be highlighted in the BOQ itself so that such points are not missed. BOQ is subdivided into a number of sections according to the type of work. The numbering and order is the same as that followed for the Specifications. 

Organization 

The wording of the BOQ has to he simple and concise but should specifically convey what it item covers. For further clarification specifications should be referred to. It is therefore important that the specification for an item of work includes a brief note on mode of measurement, inclusions and exclusions. For instance the rate for reinforcement includes not only the cost of cutting, bending, typing etc. but also the cost of binding wire and cover blocks. Binding wire and cover blocks are not paid  for separately. 

Extra Items 

During the course of construction, certain items of work not mentioned in the tender documents may have to be carried out. These are called extra items of work. The rates, mode of measurement, and the specifications for such work should be determined before taking up such work. Usually, the Contractor is asked to submit a rate analysis for such items of work. The rate analysis includes the cost of materials, labour, plant, machinery, overhead and the profit margin of Contractor. These rates and specifications known as Extra Item Rate List (EIRL) has to be mutually accepted and forms a part of contract.
