TRANSCRIPT
Boundaries and Surveys• Need for boundaries and surveys
precipitated civil engineering as we know• Surveyors
▫ Noted and marked foundations of monuments▫ Dividing land into parcels
• Egyptians used surveying to predict Nile River flood waters
• Romans learned from Egyptians and Greeks the importance of surveying▫ Aqueducts and roads designed from
surveying methods
Arabic people & the astrolabe
•Astrolabe - Fixed surveying method linked to the stars
•Arabic people developed proficiency with the astrolabe after the fall of the Roman Empire
•Arabic culture also responsible for:▫Development of Trigonometry▫Practice of triangulation to achieve
accuracy
Recognition•Civil engineering named to
distinguish between military and other engineers
•Europe and U.S. recognized those who completed large-scale projects as “civil engineers” (18th Century)
•1782 - John Smeaton of England molded himself as a Civil Engineer
•1793 - Society of Civil Engineers created in England▫1818 - Named changed to Institution
of Civil Engineers
United States Societies of Civil Engineering • Franklin Institute in
Philadelphia (1824)▫ Informal society of
engineers• American Society of
Civil Engineers (ASCE) ▫ Formed November 5,
1852▫ Present and active
today

Jacob’s Creek Bridge
•World’s first modern suspension bridge•Located on the road between Uniontown,
Pennsylvania and Greensburg, Pennsylvania•Designed and built by James Finley for $600 in
1801•Bridge demolished 1833, five years after Finley
had passed away in Uniontown
Factors to take into account• Strong enough to
resist reservoir water backed behind dam
• Impervious to water▫ Resists leaks and
erosion• Water cannot find way
into dam• Accommodates
overflow

Evolution of Roads
•Markings used to designate paths to desired destinations
•Invention of wheel brought on roadways
•Evolved from dirt roads into paved surfaces with drainage systems to divert water off of them
Paved Roads History
•3000 B.C. - the Herappa and Mohenjo-Daro civilizations in the Indus valley developed paved roads with drainage systems underneath pavement
•2500 B.C. - Lake Moeris Quarry Road▫World’s oldest paved road▫Was eight miles long (only 4 miles remain)
Those Romans…• 312 B.C. - Road from
Rome to Capula▫ 130 miles
• 144 B.C. - First high-level aqueduct ▫ Hydraulic cement
introduced in design• Over 372 roads
constructed with a combined distance of 53,000 miles
• Roadways suffered with retreat from Britain
Roman road cut into Italian Mountain

Roads considered a value??
•600 years after Britain invasion retreat, Norman invasion showed roads are considerable value
•The church maintained roadways and constructed inns and places of rest
•Henry VIII dissolved the monasteries with his self-appointed Supreme Head of Church of England in 1534
El Camino Real
• 1500’s Spaniards and Colonials developed first inland transportation route into U.S.
• Original use for political and military use only
• Beginning of interstate highway system

History of Tunnels
•600 B.C. - Samos Aqueduct Tunnel▫Water supply routed through a hill on
Greek island•Persian and Armenian tunnels in Iran
brought water to towns in the 8th century•By 17th century, tunnels widely used to
route canals through hills rather than around
Tunnel History cont.• Marc Isambard
Brunel developed a shield for boring under the Thames River in 1820
• Dual tunnels run 1200 yards
• Completed in 1841
• First time tunnel cut under a body of water
Marc Isambard Brunel(1769 - 1849)

Alfred Nobel’s Dynamite•Most significant advancement in
tunneling•Alfred Nobel born in 1833 in Stockholm,
Sweden to a family of engineers•Father sent him abroad to learn about
chemical engineering to expand horizons
•Alfred returned and concentrated on nitroglycerine as explosive
•Brother and several others killed in an explosion
Alfred Nobel cont.• Nitroglycerine banned
from Stockholm city limits• 1864 found way to handle
explosive safe• Nobel built labs and
companies in more than 20 countries
• Holds more than 350 patents
• Immense fortune amassed• Nobel Prize founder in will

Water Supply and ControlPanama Canal under maintenance
http://www.photoatlas.com/pics02/pictures_of_panama_73.html
Definitions• Dams - barriers constructed across a waterway
to control the flow or raise the level of water• Aqueducts - pipes or channels designed to
transport water from a remote source▫ Usually takes advantage of gravity▫ Bridge-like structures support a conduit or canal
passing over a river or low ground• Canals - artificial waterways or artificially
improved rivers used for travel, shipping, or irrigation
Industrial Engineering
•International commerce increases brought about an increase of competition amongst suppliers
•Main role is to combine workers, machines, and materials in order to increase productivity and reduce waste
•Philosophy traced back to tribal cultures▫Created more efficient tools and made best
of everyone’s specific skills

•Assistant needed to manipulate cord in order to give alternating rotary movement
•Earliest illustration of lathe found in Egyptian tomb of Petosiris
Pole Lathe
•Developed in 12th century•Size and complexity of work to be done
increased, bringing the invention about•Designed with heavier wooden
construction to be more rigid and powerful than previous designs
•Continuous drive machine with a large wheel cranked by an assistant created to turn metal
Pole Lathe Examples• 1500 - Leonardo da
Vinci’s treadle and crankshaft
• Spaichel’s development in 1561 using human power

•Mechanical Engineering recognized as profession in England in 1847 and U.S. after 1850
Steam Engines• James Watt developed
new model steam engine in 1778▫ Engine cooled steam
in a condenser separate from the main cylinder
• Spurred the application of steam to water, land, and air
