blog we discuss about quantity survivor and regarding other parts of connecting
with quantity surveying.

A Quantity Surveyor is a construction
professional whose main expertise is primarily to carry out an estimate,
project cost control and quantity take-off.
His duties also include commercial, risk and contract management to
ensure that the party he works for gets the best value for money and to allow
for a smooth project flow from inception to completion.
Quantity surveyor is not limited to
construction field. He can work in

Who are the separate workers work with QS?
So many jobs & positions connect with the
QS, in construction field. These named as “building team”.
The Building Team
The Employer - The
employer, who is called the client or building owner, is the organization or
person who commission the construction project and who pays the cost of the
work. Much of the success of a building contract will depend on the employer.
To ensure satisfactory outcome, he should select a competent consultant and
cooperate effectively with him. The
employer should, as far as possible, refrain from requesting changes to the
original design as the work proceeds. Such variations often results in delays
and disorganization of the work can give rise to increased costs and claims
from the contractor. It is most
important that the employer shall honour the certificates issued by the
consultant within the period inserted in the appendix to the form of contract.
Contractors should be timely paid to prevent cash flow problems. Finally, it should be borne in mind
that most employers want what they need, when they want it, and at a price they
can afford.
The Consultant
- The consultant is regarded as the leader of the building team. The consultant receives the commission to design and supervise the erection of the building. Consultant will certainly need assistance from other specialists, for example, structural engineers may be required to design the structural frame, mechanical and electrical to design the M & E services, and quantity surveyors to advice on contractual and cost aspects and prepare bills of quantities and other contract documentation.
The consultant is usually wholly and entirely responsible for the preparation of the contract, including the formulation of designs for the project. He is virtually in sole control of the project until the contract is signed. He should make it clear to all tenderers that he is acting on behalf of the employer. Once work has started on the site, he is responsible for ensuring that the contractor carries out the whole of the work in accordance with the contract and to the consultant’s reasonable satisfaction. Consultant is normally the only member of the building team with an overall view of the project, and his functions usually include liaison with the employer, representatives of local authorities, and with other consultants and specialists. Liaison with the contractor will start at an earlier or later stage depending on the type of the contract.
The consultant’s first task, after
appointment, is to discuss with the employer his building requirements. This
often emerges as a list of needs, commonly referred to as “the brief”. When
both site details and the principal building requirements are known,
preliminary designs can be prepared. At this stage, the consultant will begin
to select his team.
In preparing preliminary schemes it is
generally necessary to consider the comparative costs of alternative proposals,
and a quantity surveyor should be appointed.
The consultant’s procedure then follows often
on the following lines:
1. Preparation
of preliminary schemes, including estimates, as part of a feasibility study.
2. After
approval by the employer, preparation of sketch plans and approximate
estimates.
3. Preparation
of structural and services schemes either by consultants or specialist sub-
contractors.
4. Preparation
of cost plans in consultation with the quantity surveyor.
5. Preparation
of working drawings and invitations for tenders from specialist suppliers and
sub- contractors, if these items are to be dealt with as prime cost sums.
6. Preparation
of bills of quantities with quantity surveyor.
7. Suitable
contractors will be invited to bid. To enable them to reach a firm decision,
they will be informed of the general nature of the work, the date when bills
will be available, and the dates for submission of bids and completion of
works.
8. Formal
invitation to bid with full documentation.
9. Receipt of
bids, evaluation of bids, advice to employer on selection of contractor and
preparation of contract document.
10. Supervision
of construction work.
11. Certifying
payments to the contractor throughout the contract.
12. Issuing
variation orders and other consultant’s instructions as necessary.
13. Directing
how provisional sums are to be spent.
14. Securing and
remedying of defects at the end of defects liability period.
15. Certifying
the final account.
The consultant acts as expert adviser and agent
for the employer. The contractor is justified in treating every order received
from the consultant as a direct order from the employer.
The Quantity Surveyor
- Construction cost, construction management and construction communications
are all key problem areas for an employer who has commissioned an important
building or engineering project. A quantity surveyor is professionally trained,
qualified and experienced in dealing with these problems on behalf of the
employer. He is essentially a cost expert whose prime task is to ensure that
the project is kept within the agreed budget and that the employer obtains
value for money.
Some of the services he offers are
preliminary cost advice and cost planning, preparation of bid documents, advice
on type of contract and method of obtaining bids, negotiation with contractors,
and valuation of work in progress and settlement of the final account.
He will at all times need to collaborate very
closely with the consultant.

The Project
Manager
- Roles played by project manager will be described later. The Contractor - The
contractor is the person or the firm who undertakes to complete a building
project in accordance with the contract documents on behalf of the employer. He
should have the full control of all operations on site, including the work
carried out by nominated subcontractors. The contractor is to proceed regularly
and diligently with the works and to complete by a specified date. Failure to
comply with this requirement may render the contractor liable for the payment
of liquidated damages. He receives all his instructions through the consultant.
But he has dealings with other parties to the contract, such as the quantity
surveyor, when he measures and values completed work. The contractor employs personnel to take
charge of work on the site and for large projects there can be a site agent.
The contractor often employs a quantity surveyor to safeguard his financial
interests. The Subcontractor / The
Supplier - Roles played by subcontractors and suppliers will be described
later. The Clerk of Works / The Resident Engineer - Roles played by above
personnel are described later.
What
is role of QS in construction field?
The Role of the Quantity Surveyor As building
work increased in volume and complexity, employers became dissatisfied with the
method adopted for settling the cost of the work and recognized the advantage
of employing an independent quantity surveyor. He had to prepare an accurate
bill of quantities to be priced by bidding contractors and who would measure
and value any variations that might occur during the progress of the works. It
is defined the quantity surveyor’s role as to ensure that resources of the
construction industry are utilized to the best advantage of society by
providing, the financial management for projects and a cost consultancy service
to client and designer during the whole construction process.
The following briefly describes the Role of the Quantity Surveyor in detail.
Preliminary
Cost Advice - From the inception of a new building project, the quantity
surveyor has to give practical advice on the likely cost of the scheme. He may
advice on the comparative costs of alternative layouts, materials, components
and methods of construction. He can also assess how long it will take to build
and can produce estimates of future maintenance and operating costs. Once the
employer’s brief is finished, the quantity surveyor can prepare a realistic
budget and a cost plan showing the distribution of costs over the various
elements.
Cost
Planning
- Cost planning aims to help all members of the design team to arrive jointly
at practical and efficient designs for the project and to keep within the
budget. Effective cost planning will help to ensure that everything follows in
accordance with the estimate, from the successful contractor’s tender to the
final project cost.
If the employer decides to change his plans
and introduce variations, the quantity surveyor will assess the cost
implication. Constant monitoring means that the risk of overspending can be
seen at an early stage and prompt corrective action taken.
Cooperation
between Consultant and Quantity Surveyor – for cost planning
The Quantity Surveyor acts as a specialist
adviser to the consultant on all matters concerned with building cost. He
offers considerable assistance to the consultant in advising on the financial
effect of design proposal and so helps in ensuring that the money available is
put to the best possible use and that final costs are kept within the agreed
budget.
Where the estimated cost of an element
exceeds the cost target, then either the element must be re- designed or other
cost targets reduced. Where a number of design elements would have to be
adjusted to keep costs within the total cost limit and this would result in a
building of undesirably low quality, the design team should request additional
funds from the employer.
Contractual
Method- Numbers of contractual procedures have
evolved from competitive bids, as the traditional method, to negotiated tenders
with a single contractor and “design and build” contracts, where the contractor
undertakes the whole task of design and construction. The quantity surveyor
canadvice on the best form of contract for a specific project.
Bidding -
Competitive bidding, often from a selected list of contractors, remains a
common basis for construction contracts. Bills of quantities are fundamental to
this process. Bills of quantities translates the drawings, schedules
and specification notes in to a document listing in detail all the component
parts required for the project. This enables each contractor to calculate his
bid price on exactly the same basis as his competitors. In the absence of such
a bill being prepared on behalf of the employer, each contractor will have to prepare
his own quantities in the limited amount of time allowed for bidding.
Choice of
Contractor- The quantity surveyor provides sound and
practical advice on contractor selection. The quantity surveyor will take
factors such as, industrial relation record, past performance, in to account in
making recommendations to the employer on the make up of the selected list.
Valuation of
construction works - In most construction contracts, the contractor is paid monthly.
The quantity surveyor will value the work carried out each month on the project
and submit a recommendation for certified payment. He will also settle the
final account and prepare financial statements for the employer. It is
important to ensure that any variations, claims or extras do not raise the
likely final account figure above cost limit. It is necessary to monitor the
financial effect of variations and these should be costed by the quantity
surveyor before they are issued.
The Role of
the Quantity Surveyor in the public and private Sectors
In
both the public and private sectors, the quantity surveyor as a member of the
design team, advice the employer and consultants on the probable costs of
alternative designs. His advice enables design and construction at all stages
to be controlled within predetermined limits of expenditure.
He prepares bills of quantities and
negotiates with contractors, prepares forecast of final costs and valuation for
payments to the contractor as work proceeds.
He is responsible for the measurement and
valuation of variations in the work during the contract and for the preparation
and agreement of the contractor’s final account.
The Role of
the Quantity Surveyor in the Contracting Organization
In contracting organizations, the duties of
the quantity surveyor will vary according to the size of the firm employing
him. The quantity surveyor employed by the contractor will aim to secure
maximum payments for the work done at the earliest possible time to avoid any
possible cash flow problems. This has however to be undertaken within the
provisions of the contract and the contractor cannot receive more than his
contractual entitlements.
The contractor’s quantity surveyor’s
activities can include preparing bills of quantities for small projects,
collecting information about the cost of various operations from which
contractor can prepare future estimates, preparing precise details of the
materials required for the contracts in hand, compiling target figures so that
operatives can be paid production bonuses, preparing interim costing so that
the financial position of the contract can be ascertained as the work proceeds
and appropriate action taken when necessary, planning contracts and preparing
progress charts in conjunction with site management, making application to the
consultant for variation orders if drawings or site instructions vary the work,
agreeing the value of variations and subcontractors’ accounts, and comparing
the costs of alternative methods of carrying out various operations such as
temporary works, so that the most economical can be adopted.
