An approximate bill of quantities (sometimes referred to as a notional bill of quantities or provisional bill of quantities) can be used on projects where it is not possible to prepare a firm bill of quantities at the time of tendering.
.
Then, what is approximate quantity method?
This estimate is based on measurement groups where Bill items with the same dimensions (in metres or square metres) are grouped together. For example, in an Elemental Estimate, you cannot group Roofs with Ceilings & Soffits, but in the Approximate Quantities method, you are free to group the two.
Secondly, what are the types of bill of quantities? According to NRM2, RICS new rules of measurement, Detailed measurement for building work, there are two types of bill of quantities; firm and approximate.
