INTRODUCTION:
The roles of Engineering
Survey in Construction
Industries

4. 4
Construction industries can be
classified into two:
Industrial works
Physical development construction

5. 5
Industrial works/ business

Supporting construction activities, such as:
for the production of construction
materials i.e. metal, steel, electrical
components, sewage, sanitary, air
conditioning, painting, tiling, etc.

6. 6
Physical development
 constructing buildings on
ground/land
 Residential : house, hotel,
banglo, terrace, condominium,etc

7. 7
 Non residential :
Social, economy and religion: e.g hospital,
mosques, temples, shopping centres,
schools, offices, hotels, airports,etc
Security and defense: army camp, police
station, etc
Sport and recreation: stadium, swimming
pool, etc.

8. 8
Engineering projects:
Transportation: airports, ports,
railways, bridges, etc
Power supply: reservoirs, dams,
canals, tunnels, etc

ES involvement:
Design stage: Provide ‘detailed map’ for preparing
layout plan, designing of the proposed building/
monument
Construction and Setting out stage: Establishing
Horizontal as well as Vertical control at the site,
directly involve in construction activities
Checking and Monitoring stage: relevant tests and
analyses

15. 15
“Engineering surveys establish control points by
traverse, baseline, or other methods to obtain
information required for engineering designs and to
set out construction from design drawings by use of
these control points. Topographic surveys, and the
maps produced by them, provide horizontal location
information and elevations needed for the design of
structures such as buildings, dams, canals, highways,
bridges, transmission lines, and sewers. Using the
engineering designs these works are then laid out
from the same control points used in the original
engineering surveys”. (http://encarta.msn.com)
ES and its roles in development process

“…... ALL THE SURVEY WORK REQUIRED BEFORE,
DURING AND AFTER ANY ENGINEERING WORKS”
(A. BANNISTER AND S RAYMOND, 1992)

Measuring angles using an old version theodolite
Data
collection
activities

18. 18
Surveying with modern equipments

19. 19
Establishing controls and acquiring data using satellite-based
technology, e.g.GPS

20. 20
Monitoring works
To ensure that the buildings/
constructions in good and safe
according to specified standard

 Engineering surveys play important
roles in the design, construction and
monitoring of physical development
