A quantity surveyor is a professional in the construction industry responsible for building costs. They prepare cost estimates, bills of quantities, evaluate tenders, and monitor costs throughout a project. A quantity surveyor works with architects, engineers, contractors, and suppliers. They use drawings and specifications to take off quantities and compile the bill of quantities, which is a list of materials, labor, and equipment for construction. Modern software like Revit allows quantity surveyors to directly measure and calculate quantities from 3D models for faster bill preparation.

11. The Inter-relationships of
a Quantity Surveyor

12. ● Architect will design the building.
● A QS will be cost adviser and monitor all financial
matters to architect.
● QS has experience on the type of work envisaged and
usually the architect will be able to recommend a
number of appropriate QSs to interview.
The
Relationship
between
Quantity
Surveyor and
Architect

13. The
Relationship
between
Quantity
Surveyor and
Engineers.
Types of Engineer in
Construction Industry:
1. Civil Engineer
2. Electrical Engineer
3. Mechanical Engineer

14. The
Relationship
Between
Quantity
Surveyors and
Contractors
Quantity
Surveyor
● Quantity Surveyors would be representing their
employer’s interest either the client or the
contractor.
● They always look after contractors’ commercial
and financial interests to make their employer in
the more controversial contractual areas
Evaluate and monitor payment to contractors
at various points of construction

15. The
Relationship
between
Quantity
Surveyor
and the
Suppliers.
● As a part of a project, a contractor
must endeavour to procure a
supply chain in a timely manner.
● The QS plays a vital role in this
process because it requires a
commercially-aware person to
drive activities and ensure awards
are placed on time and within the
budget.

16. Example of Drawings

17. Typical Quantity Surveyor will be like:
● Basically, Quantity Surveyors
don’t draw. They READ
drawings instead.
● a Quantity Surveyor will study
drawings and specifications
about a new building normally
provided by architects or
engineers.

18. QS Read &

19. Architectural Drawings
● Sketch /
Diagram / Plan
use to design
& construct
● Show building
elements &
form for
construction
works

20. QSes use them for the estimation of
cost and materials.

21. Construction Drawings:
● Contract documents
that give
representation of
work
● To work on the actual
building of the design
● Provide all
information require in
construction activities
in writing & drawing
form

22. QSes use them as a basis for cost control during
the construction process.

23. Tender Drawings:
● A formal invitation to
suppliers to make an offer
to the buyer for the supply
of goods and services.
● Sufficient details are
described
● Use for estimating &
pricing the cost

24. Quantity surveyors check them to see that no substantial errors had
been made. They then submit the detailed reports on the tenders to the
client.

26. ● A cross section drawing of a path
showing width & specification
detail for each construction layer
● Include general arrangement
drawings showing site location, the
position on the site, means of
access to the site, floor plan,
elevation and section.
Contract Drawings
Formal agreement between the buying
organisation and the supplier setting out what
services and products the supplier is contracted
to deliver and within the timeline and contract
price.

27. Annotations of measurements, colors, and materials,
was appended to the contract.

30. When a 3D model is complete with
specifications, the bill of Quantities is
able to be compiled instantaneously.
Bills of Quantity:
The bill of Quantity is a report ready by the expense
expert (frequently an quantity surveyor)
● gives particular measured amounts of the things of work
recognized by the tender drawings and particulars in the
delicate documents.
● The amounts is measured in number, length, zone,
volume, weight or time.
● Requires the specific design and specifications that has
been completely prepared.

31. Revit : BIM
● BIM(Building information model)
● Software used by QS to count and
calculate the material directly by using
example of design/build firm that uses an
API(application programming interface)
from Revit Autodesk.
● Time, expense, and sustainability are
crucial in today's construction industry.
Books
● Malaysia Standard Method of
Measurement 2nd edition(SMM 2)
● Contains specification, measurement,
and describing the materials.
● As reference.
