Bill of Quantities is synonymous with Quantity Surveyors. The profession was
said to have emerged in England at the beginning of the nineteenth century,
although the firm of Henry Cooper and Sons of Reading was established as early
as 1785. Prior to the first recorded usage of the term "Quantity
Surveyor" in 1859, the terms "measurer", "custom
surveyor" or "surveyor" were used.(ASAQS,
2006)
BOQ emerged in the 19th century after the Industrial
revolution in Europe. In those early days the Quantity Surveyors acted for the master
tradesmen, measuring the work after completion for use in making
payment to workers and frequently submitted as partisan Final Accounts to the
building owner to claim for payment. Later on it was the practice of the
building owners to call for tenders before any work was undertaken. A procedure
was then developed to invite several master builders to submit tenders
for the total price of the project rather than a collection of prices
from master tradesmen or what is known today as sub-contractors.
(ASAQS, 2006).
For the purpose of submitting the bid or tender, each
builder then has to come out with accurate estimates of the project cost or
tender. It was done by measuring and quantifying the quantities of all
materials and labour necessary to complete the work, i.e. preparing a bill BOQ for
the project. As each builder had to prepare his own BOQ for each
project, they came to realise that they were duplicating a lot of effort by
each measuring the same quantities from the architect's drawings. They realised
that it is more economical for them as a group to employ one surveyor to
measure the work and prepare the BOQ for them.
The builders will then price the BOQ and
submit their tenders on the same basis. They would share the cost of the Quantity Surveyor (or the successful builder will
pay the surveyor) and include the payment in their bids. On the part of the
building owners themselves, since they ended up paying for the Quantity Surveyor's fees, it finally dawned on them
that they might as well employ him directly and get some cost advice from him
as well. (ASAQS, 2006; Myles, 2006, CIQS 2006).
Apart
from some minor changes in term of method of measurement, content and format of
presentation, BOQ is still a document
detailing description and quantities of all the construction work of a project.
It may now may come in elemental, trade, work section or operational form. With
the advent of ICT, the process of preparing s has evolved from the tedious
manual and time consuming processes to semi-automated or fully automated
processes involving the use of computers and sophisticated specialised
software. But the whole process is still involving the toiling over many
hundred drawings
in doing the time consuming “taking off”,
many hours of meetings and discussion with the client and other consultants and
drafting, checking, editing and printing the 300 – 500 pages document.
