Preamble
Preambles are clauses usually inserted at thehead of each work section bills, and principally
contained descriptions of material and
workmanships as found in specifications,
together with another relevant information of
which the contractor should be aware in pricing.
Inserting the preamble in the B.O.Q, the lenth of
the work descriptions are reduced and thespecifications is not necessary if they provide the
information

Functions of Preambles

Specify the standard of the workmanship
required,Assist in pricing measured work,
Repetition of same information item by item
