Unit Rate Contract


UNIT RATE CONTRACT:

Such contracts are drawn from PWD-8. As far as possible all tenders except for small works should be invited on this form. The contractor is required to quote separate individual rates for the different items appearing in the schedule of quantities. The contractor will not be in a position to quote the rate unless he analyses it in detail. The element of inherent uncertainity and guess is ruled out completely. It is possible to compare the rates as per schedule of rates, prevailing market rates and the contractors quoted rates for better appreciation of tender. Thus, the approach is more scientific.

The only draw back in this case is 'front loading of tenders' i.e. the rate quoted by the contractor are more for the items to be executed at the start of work. The risk involved in such cases is abounding the work the contractor.

(i) The WT strategy aims to minimize both weakness or threats and may be called the minimum strategy. It may require that the company, for example, from a joint venture, retrench or even liquidate.
