3. INTRODUCTION :
 Surveying is the technique, profession, and
science of determining the three-dimensional
positions of points and the distances and angles
between them.
 The utilities means public use appliances which
are located in subsurface of earth.

4. Spiking a buried power cable or fracturing a
pipeline is a cause of serious and dramatic danger
that can even kill.
Knowing their presence and position helps avoid
the possibility of damage

5. Lines for telephones,
Electricity distribution,
water supply mains

6.  The utilities which are public or private may
include lines for telephones, Electricity distribution,
natural gas, Television cables, Traffic lights, water
supply mains, Waste water pipes and also oil and
gas pipelines, Rail and Road tunnels etc.
 Utility Surveying is the process of identifying and
labeling public utility mains that are underground.

7.  UUS is detecting and locating the buried utilities
without excavation, drilling or boring.
 In the innovation of these techniques or system
developed are ground penetrating radar(GPR),
Radio Detection and Acoustic Wave
Technology(AWT).

8. Utility accidents in the World
Direct Loss
Indirect Loss
Loss of time
Legal problems
Additional cost
Insurance raised
Loss of reputation

9. NECESSITY OF UTILITY SURVEY:
Ensuring safety of both public and work force
during construction work
Minimizing cost and disruption arising from
damaged to existing utilities.
Minimizing project delays.
Have a clear knowledge of where utility run and
which area are highly congested.

10. Avoiding accidental damages to existing
underground services
Avoiding damages to Utilities During Excavation

11. METHODOLOGY
The selection of appropriate techniques is essential to ensure
effective detection.
Methods of Utility Locating:
1. Ground penetrating radar (GPR)
2. Induction utility locator
3. Acoustic location method
4. Magnetic survey
5. CCTV Surveys
6. Magnetic Locators
7. Electromagnetic Detection

12. Ground penetrating radar (GPR)
The GPR system consists of antenna, which houses the transmitter
and receiver; and a profiling recorder, which processes the received
signal and produced a graphic display of the data.

13. CASE STUDY
• Discussion on the development of underground utility
tunnels in China by Chao Yang in 2016t al
China is a too populated compared to its area.
So that there is need of this type of utility provision.
Todays, most of urban utilities in China are directly buried under
the roads.
 First utility tunnel was built at Zhanjiang Road, Pudong District,
and Shanghai.
In 2015,china selected to construct pilot projects of underground
utility tunnels which combines all types of utilities in that.

16. ADVANTAGES
We will come to know in advance or before
commencement of any work.
Without disturbance to existing utility.
Cost of repairing of damaged utilities can be
reduced.
Damage due to accidental breakup of services can
be minimized or avoid.

17.  Land pollution can be avoided.
 Speed execution of infrastructure development
work can be retained.

18. DISADVANTAGES
 Type of utility can affect on result interpretation.
 Type of soil can also affects on surveying.
 Experienced person should required for
interpretation of utilities.
 Detect underground utilities upto few depth.
 We cannot provide a 100% guarantee that every
single utility has been detected.

19. LITRATURE REVIEW
1. Jim Lester et al,
(2007)
He has studied the significance lies in its use of real-world GPR data to
demonstrate the performance characteristics of the filtering process and its
validation with the actual condition found during excavation.
2. Julian Canto-
Perello et al, (2009)
In this he discussed how compatibility of utility system networks with
highway system networks could be greatly improved by appropriate
attention to utilidor systems in urban planning.
3. Dr. Sanjay Rana
(2011)
He discussed various tools available for mapping. He also provides an
overview of various non-destructive geophysical techniques available for
underground investigations. Basic principle, application areas, advantages
and limitations of various techniques has been presented.

20. 4. Zico Kai Yip
Kwok (2011)
In this he mentioned the availability of the multitude of method
statements, specifications, training manuals, and the contracts documents
produced for the vast number of underground utility survey contracts.
5. M. Seedat et al
(2012)
He has discussed the different types of surveying. To a large degree, the
extent of urbanization and relative worth of the land determine the method
of surveying most appropriate. The equipment used varies with the need
and nature of survey.
6. Shuai Li et al
(2015)
He studied underground utility lines being struck is a long-standing
problem worldwide, causing public service disruptions, project delays,
cost overruns, property damage, injuries, and fatalities that cost billions of
dollars each year. To overcome from this he introduced some efficient
ways.

21. 7. Chao Yang et al
(2016)
In this, he mainly reviews the history of the construction of the
underground utility tunnel in China and points out the existing problems.
Based on the analysis of several construction cases, some practical
experience on the large scale promotion and construction of urban
underground utility tunnels in China are given from the decision-making,
planning, construction, management and other aspects, which may be
helpful to the development of underground utility tunnels in other
countries.
8. Ganesh S Ragade
et al (2016)
He had studied that every local government’s maximum activities
estimated to be geographically based. For example plats, zoning, public.
Modeling of underground infrastructure is one of the most crucial among
other government activities.
9. Lalit Desai et al
(2016)
He had discussed underground utility survey is the process of identifying
and labeling public utility lines which is underground. These line may
include lines for telephones, electricity distribution, natural gas, cable
television, fiber optics, traffic lights, storm drains, water mains, waste

22. CONCLUSION
 From this seminar I studied that before starting of
any subsurface work it is necessary to survey it
for avoiding the damages of utilities which are
located underground without excavation.
 It reduces regular crashes with poles and possible
fatalities.
 For developed and developing country it is giving
too much scope.

23.  Reducing health hazards, improve the aesthetics
of neighborhood.
 It helps to know what exactly below the ground.
 It helps for planning and installations of new
utilities.
 Lack of knowledge on this may result in fatality
and catastrophic damages of existing underground
utilities and disruption to utilities services.
