The document discusses automation and its significance in construction, highlighting its role in reducing human intervention, improving efficiency, and the economic impact on labor. It also covers the history of automated construction techniques, including notable experiments and systems developed for efficient building processes, detailing the advantages of precast materials and digital photogrammetry applications in civil engineering. Furthermore, it emphasizes the benefits of automation in enhancing workplace safety and productivity within the construction industry.

2.  Automation : Derived from ancient Greek =
meaning self dictated
 It is the use of control systems such as computers
to control machinery and processes
 Reduces the need for human intervention.
 Mechanization provides human operators with
machinery to assist them with the physical
requirements of work, automation greatly reduces
the need for human sensory and mental
requirements as well. Processes and systems can
also be automated.
 An increasingly important role in the global
economy and in daily experience.
 Engineers strive to combine automated devices
with mathematical and organizational tools to
create complex systems for a rapidly expanding
range of applications and human activities.

 REDUCESTHETIME REQUIRED FOR
CONSTRUCTION
 HEAVY WORK CAN BE COMPLETED

 THE POSSIBILITY OF HUMAN ERROR IS
REDUCED
 SECURITY OF DATA

6.  Unemployment at the cost of modernization.
 Leads to brain-drain from the country.
 Requires a high capital cost for setting up and maintenance
 Skilled and expert handlers or workers are required due to
the need of high technical knowledge to operate the
machines.
 Untrained workers cannot be employed which increases
the initial cost of project.

7. PRECAST BLOCKS
 The cement concrete blocks which are cast in a
rectangular shape mould ,either hollow or solid,
on site or in factory, are called as precast
blocks.
They are mostly used for:
 Girders for bridges, bridge piers (Balgandharv
bridge, Harris bridge Pune)
 Beams for large spans (Nehru memorial
hall,Pune)
 Electric poles
 Fabrication of R.C.C pipes, concrete piles

8. ADVANTAGES OF USING PRE CAST
BLOCKS
 Hollow blocks are light in weight –used for
construction of partition wall
 Can be used anywhere on the slab or the floor
 Strong
 Durable
 Posses high compressive strength
 Less material required so helps achieve
economy

10. •Many construction equipments and machines make it possible to reduce
the time of construction and also improve the efficiency of work.
Some examples are:
Concrete mixing machine
Backhoes
Bulldozer
Beam moulds
Trailers
Wet mix macadam plants
etc

13.  On July 4th, 1965, in Crespellano, (Bologna), Dante N Bini
made the world's first attempt at using an automatic, self-
shaping construction process to build a fully reinforced
concrete structure on a previously built floor and footing
system
 The experiment was successfully completed in three hours.
 In only three hours, a dome 12 m. in diameter and 6 m. In
height had been pneumatically lifted from the ground and
shaped into an hemispherical thin shell structure.

14.  A year later, on July 6 .1966, in Castelfranco
Emilia, (Italy) another major experiment was
undertaken.
 In less than four hours, 15 cubic meters of wet
concrete and flat steel was shaped into an
elliptical reinforced concrete dome 36 m. in
diameter and 12 m in height.

15. Various systems of
automated construction

16. Mini shell system
 The fastest and
cheapest systems
for building
permanent shelters
 Very suitable for
low-cost
housing.
 The erection time
reduced to 30
minutes.
 The required man
power results in 1.5
hours per man
per each for sq.
m. of covered area.
Sequences of construction of the Minishell Tourist Village in Cairns, Australia. (1980)

17. The only two problems experienced during
the application of this method of
construction were:
a) Structural weakness in the "vertical" portion
of the walls when the concrete was still green.
b) Lack of precision and symmetry in the shape
and size of the four automatic openings.

18. BINISTAR SYSTEM
 Originally conceived in
Australia in 1979.
 It is the only
demountable,
automatic, method of
construction capable to
shape large-span metal
space-frame structures
of different shapes and
dimensions.
Sequence of construction of Binistar structures in Italy
and details. (1986-68)

19.  In the same period the two other
conceptual systems were developed :
 The "Fold-A-Struct"
 The "Autotent"

20. Fold-a-struct produces :
 An instant, demountable, square-based,
class-room unit, made up of four identical,
mass produced components provided with
"inner stored energy'' which contribute to the
self-assembly process.
(Fig. 8): Fold A Struct. self-assembling model (1987)

21. It produces:
 A folded space frame which may be utilized as a
mini-shelter.
 This shelter is designed as a civilian or military tent
which is dropped by low-flying aircraft in case of
emergencies.
 The autotent self-shapes during its fall and is
provided with an identification light and with a
survival kit.

25. Close Range Digital Photogrammetry
Introduction
• Photogrammetry:
Photogrammetry is the technique of measuring objects (2D or 3D)
from photogrammes.
Its most important feature is the fact that the objects are
measured without being touched.
•Automated photogrammetry : All functional aspects of photogrammetry,
i.e., triangulation, elevation data extraction etc are now being automated to
some degree. The drive towards automation has been triggered not only by
the continuing necessity to reduce costs, but also by the need to generate
new products and to utilize other than conventional mapping photography .
• Photogrammetry can be divided into:
Far range photogrammetry
- Aerial photogrammetry, etc
Close range photogrammetry
- Terrestrial Photogrammetry, etc

45.  Construction Automation eliminates the need
for workers to operate in uncomfortable and
hazardous conditions, while concurrently
saving time, reducing costs and improving the
quality of the work place in the construction
industry.
 It is well known that in spite of the
employment of sophisticated machinery and
equipment and some recent efforts to improve
on-site working conditions, construction sites
in general offer some of the worst working
conditions existing today.
 As has already been experienced in other
industries, the application of automation and
robotics can cuts costs, environmental
pollution, and dramatically improves safety
and quality control to the benefit of living
standards in general.
