What do quantity surveyors do?

Quantity Surveyors estimate and manage the cost of construction
throughout a project. Their responsibilities begin at the planning stage
and continue through the construction period. They interpret
architectural or engineering drawings and specifications to calculate
project costs. During the building stage, they monitor expenses and
check on changes in the design of the project, to see whether costs will
be affected. They also provide monthly cash-flow forecasts to their
client and may organise the amount and timing of payments to
contractors. Quantity Surveyors work in partnership with architects,
engineers, builders, contractors, suppliers and project owners.

Be sure to involve a registered QUANTITY SURVEYOR in any construction projects you wish to undertake!

Thanks Mwenza....I have also insisted that this is the wrong forum to look for PJ's...Its least to say unethical. Incidentally, i wouldn't give you one. Remember ' chema chajiuza, kibaya cha jitembeza'?

@ swaweru,

although the quantity surveyor is always given too much attention, i would say that it is the most redudant profession and the most unneeded person in a development project....

the QS's work in a development project or construction is being the custodian of the performance bonds from the contractors and sometimes contract agreements drawn between the clients and the contractors and nothing else. This could as well be done by a lawyer.

Let us analyse your purpoted duties and responsibilities as you have described:


Quantity Surveyors estimate and manage the cost of construction throughout a project. The construction can still be done without any input from the QS as the designers (architects, civil/structural engineers and electrical/mechanical engineers can do their own costings and manage/monitor the construction financially to completion.

Their responsibilities begin at the planning stage and continue through the construction period....QSs are not designers and have little clue on what design is all about. they rely entirely on the architect and engineers for information related to design, without whom the QS is just as good as dead.

They interpret architectural or engineering drawings and specifications to calculate
project costs. . the QSs have a rough idea on the measurements of obvious quantities only like the stone walls, doors windows, the ceiling and excavations.QSs cannot carry out measurements of structural, electrical and mechanical works. In fact a QS cannot interprete the structural, electrical and mechanical engineers drawings and neither can they do specifications unless they edit bills of quantities done by others(engineers).

During the building stage, they monitor expenses and check on changes in the design of the project, to see whether costs will
be affected. Again this is something that can acurately be done by the engineers. Computation of variations and appraisals included.

They also provide monthly cash-flow forecasts to their client and may organise the amount and timing of payments to contractors. the cashflow information that the QS receives from the civil/structural and services engineers forms the basis for their advice to the client. This is actually duplication of effort. The engineers can do their cashflow predictions with precision accuracy and also compute the valuations based on the actual value of works done by the contractors. Again here the QS is not necessary.

Quantity Surveyors work in partnership with architects,engineers, builders, contractors, suppliers and project owners. As explained above the role of a QS is reduced to zero and may not be required in any construction.

i believe that QSs are paid so much for doing nothing! Come to think of it rationally.

Kaigangio- i doubt you are an architect or an engineer, my bet is you are a Project Manager.i dont want to come out as offensive, but i doubt universities world wide would be dumb enough to offer a redudant course, i doubt corparates would use the services of QS if they didnt need one.i dont think banks would be dumb enough to ask for bills of quantities from registered QS.it takes 4 years for one to finish a QSing degree, 2 more years of work experience then another exam, both witten and oral to be registered as one.lets say we wanted the Architect or teh Engineer to do the work of the QS.so add those 4 years to the 6 of the architect, or the 5 of an engineer, so guess how much they would charge you for their services. just ask a registered architect or engineer to prepare a BQ or do the services of a QS in a building project you will hear their response.

i think you should respect the services offered by the QS and other professions, its like saying the doctor doesnt need a nurse cause he can do all that work on his own.or a firm doesnt need a marketing department cause they have a sales department. or a finance department cause they have an accounts dept...hope you get my drift.

in my humble opinion, i think we dont need a project manager in a building project, that is if all the consultants did all they were required to. i am yet to come across a fully competent and ethical PM. The QS & Architect should be doing what the PM does!!

@swaweru, please be careful not to go against CAP 525, though marketing yourself within the allowed scope in accordance to the practice notes is in order.

@fresher2010..thanks for your comments. still at loss as to where I marketed myself.
From what I can see the post has brought interesting comments.
The industry is working on formalising the qualifications of project managers. The AAK has a Chapter now and you will meet many competent and ethical PM's in future.
