QUANTITY SURVEYOR’S DUTIES
BOQ preparation
Definition
In simple form it is a shopping list as we see the definition of computer as a calculating
machine.By more sophisticated way it is a “Hypothetical construct” of the building in accordance
with the designs & intents of the various client & design parties at the day it is completed. It is of
course by necessity subject to eternal variation as the forces surrounding it vary.
Clients have been impressed with the QSs skilful use of preambles to schedules of prices, “rates to
include for” clauses & the detailed approach to item descriptions. A tradesman best work is done
by the correct tool. The QS’s tool for contract is the BOQ. A professionally prepared BOQ is
undoubtedly the superior cost management tool in our industry & plays a significant part in the
estimation & cost planning process. These are prepared according to the SLS 573 (building
contracts). Although specifically designed & developed for a particular project, it is the key
element in cost data banks.
Estimating (pricing the BOQ)
Every estimate has three phases,
Stage one :-The measurement of various parts in greater or lesser detail depending on the
availability of design information.
Stage two :-The application of labour, material, transport & plant rates to those quantities
Stage three :-The application of construction & other risk factors i.e contingencies, foreign
exchange, escalation, requirements of infrastructure & accommodation in remote areas etc.
Cost data maintenance
Due to the QS’s traditional role in the building industry, the profession has been able to build up
cost libraries & databases to draw upon to produce conceptual estimates. To be able to provide
realistic information and advice, the Quantity Surveyor must have a bank of cost related data.
o Cost analysis of previous projects undertaken.
o Materials supply data both in cost and suppliers

Cost planning/preliminary project estimation
Bowen et al (1985) explains “ estimating & forecasting would seem to have basic similar
meanings, but that a ‘forecast’ is exclusively reserved for a future (not certain) event, whereas an
‘estimate’ may also be applied to existing observable situations.
Early budgetary advice should be dynamic view rather than static, so that designers can be
informed about the cost consequences of their decisions as or before the decisions are made.
Therefore, QSs must become more sensitive to the dictates of design process & to the importance
of the performance aspects of design.
Tender documentation
The tender documents mostly used are:-
• Tender conditions and
• Priceable documents e.g. bills of quantities, specifications and drawings etc.
All this process is necessary to arrive at cost and time to execute.
Tender evaluation
Tender Evaluation follows receipt of tender documents and tender report must be explicit on
recommendation. At this stage there are specific recommendation basis.
• Undertake reductions and works re-organization to meet clients budget.
• Recommend the lowest tenderer if tender sum meets clients budget or re-organized
budget.
• Prepare cash flow data where needed to match recommended tender.
Tender evaluation means, scrutinizing the priced BOQ of the tenderers for the preparation of
tender evaluation report as well as recommending the contractor to the Client/Architect. The
selection of a suitable contractor to construct a project is an essential, which requires careful way
of analyzing the documents.
Post contract administration
The major thing in good contract administration assist the contractor to confirm that all work
completed has been claimed. It also helps clients & their financiers in knowing that funds spent on
ICBT

the project do not at any time exceeds the value of work completed. Contract administration can be
roughly divided into three sections such as cash flow, accounts & claims. The QS is expected to
prepare a cash flow plan & monitor this against payment made to the contractor.
Preparation of monthly statements
Measure the work carried out & prepares interim payment application is the another major duty of
QS. He should be able to ensure that the amount is both realistic & covers all the work executed
during the month. Subcontractors work, variations, increased cost claims are also part of the
interim valuation.
Preparing final accounts
Contractor QS is responsible to do this. Final accounts includes variations, all measured items &
increased cost items etc. QS should be smart enough to incorporate all the day works, variation in
the bills if not included in interim bills.
Selection of subcontractors
Generally, the structural works are done by the main contractor & the rest is left to subcontracting
(waterproofing, aluminium works etc.). Therefore their quotations is needed, while pricing the
BOQ. So the contracting QS would call of about three subcontractors for a work and analyze the
rates & include it to the BOQ. If the contractor is selected to the project, then QS has to negotiate
with the subcontractor in order to give any discounts (if needed).
When all is said and done the Quantity Surveyor who wishes to perform diligently must ensure
that contracting parties and consultants do not get involved in any form of conflict and at the end
of the day the Client is happy that he got value for money and the Contractor is happy that he was
paid for what he contracted to do.
The QS as expert witness.
A qualified quality QS may also be required to act as an expert witness in the court of law. QSs are
venturing into new fields. One of this is the role of the expert witness in which they become very
much embroiled in the legal world. They under take claims formulation & analysis & advice
ICBT

clients & lawyers upon the advisability of pursuing an action. Unlike a witness in general, he is
special & can give his opinion in an impartial manner & submit a expert witness report including
the evidences. QS may be part of a team on a case. For example, there may be an architect & an
engineer involved to deal with their specific disciplines, & it will really depend upon the
circumstances of the case as to whether or not the QS plays a leading or subsidiary role.
Project management
It is immediately visible that many QSs have diversified into providing PM services & building
management. This is especially so in the last decade. No doubt the QS wearing a PM’s hard helmet
would be able to control & monitor the cost aspect of the project by introducing It is definitely not
an easy task for a QS to switch to PM without having the pre-requisite skills in managing the
project in terms of time, quality, human elements of the team, & money, let alone the entire
complex construction process.
Development appraisal
Feasibility studies and proposals of alternative land use. Advise on return on capital investment.
The preparation of the developer’s budget & other, matters concerned with the developer’s
appraisal of a proposed project are now being carried out by a handful of QSs in Sri Lanka.
Understanding the relationship between these factors is an important aspect of the development
process & requires an in-depth knowledge of the property market. That understanding generally
comes from the traditional QS (Brandon, 1992).
Value management
VM is a philosophy concerned with providing the product desired by the customer & the required
quality & the optimum cost (Brandon, 1992). The QS inherent ability to assimilate & manage data
in a logical manner & ultimately to communicate such data clearly & consciously means that they
are well suited for the role of value manager or team coordinator.
Facility Management
Facility management in the broad sense means to building management from design to
construction, commissioning, use & maintenance to disposal. It suggests a birth to depth approach
ICBT

to properly portfolio management, & provides an opportunity for one step management services
from the inception to demolition. To do this the QS further need to assemble information & skills
in premises management & in particular maintenance needs & cost.
Quantity Surveyor in Maintenance / Post occupancy evaluation
The recognition of local government & the increase in maintenance works has meant that many
QSs have become more aware of the needs of such work. Both private & public sectors have
produced workloads of a substantial nature meriting the attention of QSs.
When Colin Roy describe the difference between maintenance work & mainstream QS. He
pinpointed the lack of drawings as a major difference, the increased time spent on pre & post
contract site visits & emphasized the need for a system.
Whole life costing / Life cycle costing
It is typically adopted by owners as part of the strategic reassessment of their facilities. It
influences the procurement of new buildings & engineering structures & the choices about the
renewal, refurbishment & disposal (Ashworth, 2002).
Risk management
Construction industry always involves risk of unpredictability events (weather forecast, exchange
rates etc.). The risk can be on both sides, to the client & the contractor. Which one does the QS
should manage is the critical thing. The contractor is continuously faced with the variety of
situations involving many unknown, unexpected frequently undesirable & often unpredictable
factors. These factors can be grouped in together in the category of risk & uncertainty
(Ammeerullah, 1995).
Construction IT
The extent to which QS is exposed has increased tremendously. Generally computing applications
for QS have concentrated an relatively routine task measurement, document preparation, cost
reporting & so on. The emphasis has been on improving speed & efficiency by automating manual
ICBT

task. Although at the moment the majority of this is commonplace application, future
developments may be far reaching. QS have to be updated with new developments to safeguard his
profession. For e.g. Auto CAD, expert systems etc.
Arbitration / Dispute resolution A qualified quality QS is expected to have sufficient knowledge of, & comply with, legislation,
planning & building control requirements & codes of practice. QSs can utilize their construction
background also.
Mediator
Apart from arbitration, mediation seems to be taking a new role in setting disputes in Sri Lanka.
Unlike arbitration, a mediator acts as a facilitator or a ‘middle man’ in an effort to close the gap of
differences between two parties in disputes. It is quite similar to negotiation that has long been
practised in Sri Lanka, but with proactive role on the part of the mediator. QSs, having an
understanding of construction process, are one of the suitable candidates to act as mediators.
Quantity Surveyors in specialist services
In the past in Sri Lanka QSs have ignored or in some case have not been asked to cost or measure the
specialist services component of major building projects which often represents some 25% to 35% of the
total cost. It is true that the cost skills of quantity surveyors, used to control mechanical, electrical, fire, lifts
& building automation systems, has been beneficial both to the client & the specialist consultants. A strong
resistance could have been expected from the specialist consultants, as it might appear we were assuming
one of their roles. If we can produce the level of expertise & knowledge by both education & training
surveyors it will grow & become an important part of QS practices.
