The document explores technology and its evolution through various case studies, including construction methods of artificial islands and bridges. It highlights the dynamic tower in Dubai, where each floor can rotate independently, contributing to energy efficiency through solar panels and wind turbines. Additionally, the document discusses the unique engineering challenges faced in urban Chicago related to bridge designs.

3. Technology is the usage and knowledge of tools,
techniques, and crafts, or is systems or methods of
organization, or is a material product (such
as clothing) of these things.

4. Case Study on Evolution of
Technology

9. CONSTRUCTION
Initially a breakwater is made in the sea and sand is sprayed
on it in beds.
The sand is sprayed by dredging ships.
 Each rock was placed individually by a crane, signed off by
a diver and given a GPS coordinate.
The Jan De Nul Group started working on the Palm Jebel
Ali in 2002 and had finished by the end of 2006.
There are approximately 10,000,000 m3 of rocks in the slope
protection works.

10. There are three PALM ISLAND

11. PALM JUMERIAH
 It has a crown with 17 fronds
 Dimension: 5 km * 5 km
 1400 villas
 2500 shoreline apartments

12. Palm Jebel Ali
 50% larger than PALM
JUMERIAH
 Due to financial crisis price of
properties were reduced by
40%

13. Palm Deira
 8 times than PALM
JUMERIAH
 5 times than PALM
JEBEL ALI
 Dimension: 14 km to 8.5
km
 It has 41 fronds

18. CAPACITY
•Number of
lanes
•Measured
traffic count

19. World’s 1st flyover : 1842

Place : Norwood Junction Railway
Station.

21. A bridge is a structure built to span a valley, road, body of water, or other
physical obstacle, for the purpose of providing passage over the obstacle.
Designs of bridges vary depending on the function of the bridge and the
nature of the terrain where the bridge is constructed.
What is a
bridge???

22. •Nineteenth-century Chicago's geography presented unusual
requirements.
•A narrow river, with low banks, ran through the heart of the city,
requiring frequent crossings.
•Yet the navigable river was one of the world's great ports, and the
low bridges had to accommodate frequent passage of masted ships.

23. A new type of bridge,
the Scherzer rolling lift
bridge, was designed in
1894 for the
Metropolitan West Side
Elevated Railroad and
nearby Van Buren Street
crossings.

24. At the beginning of the
twenty-first century, the city
had 37 operable street
drawbridges, including 5
over the Calumet River,
opened nearly 30,000 times
a year.

26. Dynamic architecture is a
product of architecture which is
in motion.

27. The Dynamic Tower
 The Dynamic Tower is also known as Dynamic
Architecture building or the Da Vinci Tower.
 The Dynamic Tower is a proposed 420-metre
(1,378 ft), 80-floor tower in Dubai,United Arab
Emirates.
 It is under construction.

28. THE ASTONISHING
FEATURES OF THE
TOWER.
 Uniquely each floor of this tower
will be able to rotate independently
which will result in constantly
changing shape of the tower.
 Each floor of the tower is designed
to rotate a maximum of 6 meters per
minute and 90 minutes per rotation.
 The entire tower will be powered
from wind turbines and solar panel.
Enough surplus electricity should be
produced to power five other similar
sized buildings in the vicinity.
 The total construction time will be
more than 30% less than a normal
skyscraper of the same size
