Civil Engineering and Architecture

Engineering and Science:

Engineering (Technology) is:
  • the invention of things that did not previously exist
  • creation of specific objects
Science is:
  • the discovery of things that have long existed
  • creation of general theories that unify knowledge
To what extent does technological innovation flow from scientific discovery?
Designers of Three Dimensional Public Spaces
  • Architects
  • Structural Engineers
  • Sculptors
3 Measures of Design Performance:
Efficiency
  • Scientific Dimension.
  • Use of Minimal Natural Resources.
  • Form Controls the Forces.
  • Form Changes the Actions & Reactions.
Economy
  • Social Dimension.
  • Use of Minimal Public Resources.
  • Must Consider Material Costs & Constructibility.
  • Dependant upon Time & Place.
  • •Quantities are measurable but….labor & bidding process are not.
Elegance
  • Symbolic Dimension.
  • Aesthetic Motivation of the Designer.
  • Aesthetic ideas can be traced back to the earliest forms of architecture.
  • Theories on the importance of structural expression and construction techniques.

Architect – the beginnings:

  • The architect of a structure was also supposed to be the engineer, combining knowledge of geometry and materials with artistic expression.
  • In medieval times this remained true, with the concept of the architect as the “master builder”.
  • Even in the Renaissance, the ideals of Science and Beauty went hand in hand and engineering was considered to be a part of art.

Architect – the master builder:

  • Imhotep
  • Ictinus & Callicrates
  • Vitruvius
  • Michelangelo
  • Da Vinci
  • Filippo Brunelleschi
  • Bernini
  • Palladio

Changes during the 19th century

  • Before 19th century, structural forces understood only in empirical terms (observation and experiment)
  • Late 18th century – exact knowledge began to replace guesswork
  • Late 19th century – science of statics – architecturally viable
  • Structural calculations intrinsic to the employment of iron skeletal construction

The Industrial Revolution

  • New methods of structural design created and put into practice by members of a new profession – civil engineers who were previously military engineers
  • Structural expertise removed from the domain of architects
  • Mid and late 19th century – spectacular advances made by civil engineers
Schism – the split:
  • Pre-schism architect was the “Master Builder”
  • Separation between architect, engineer and constructor

What lead to the schism:

Industrial Revolution introduced new materials, methods and aspirations
Specialized schools were established
  • Ecole de Beaux Arts & Ecole de Polytechnique
  • ETH, Zurich
Architectural curricula focused on:
  • visual methods
  • product
Engineering curricula focused on:
  • numeric methods
  • process

Civil Engineers – their contributions

  • John Augustus Roebling
  • Alexandre Gustave Eiffel
  • Pier Luigi Nervi
  • Robert Malliart

John Augustus Roebling (1806 – 1869):

  • Born in Prussia, he emigrated to the United States in 1831.
  • He graduated with a degree in civil engineering from the Royal Polytechnic Institute of Berlin in 1826.
  • In 1841, he invented the twisted wire-rope cable, an invention which foreshadowed the use of wire cable supports for the decks of suspension bridges.
  • As the cable could support long spans and extremely heavy loads, he quickly gained a reputation as a quality bridge engineer.
  • Roebling utilized steel cables in the construction of numerous suspension bridges and is generally considered one of the pioneers in the field of suspension-bridge construction.

Roebling’s Projects:

  • The Brooklyn Bridge, New York, 1869 – 1883.
  • The Niagara Rail Bridge, 1841 – 1855 .
  • The Cincinnati – Covington Bridge, 1856 – 1867.

The Brooklyn Bridge, New York, 1869 -1883:

  • Overall width: 85 feet
  • Total length: 5,989 feet
  • Length of approach: 971 feet (Brooklyn approach) & 1,562 feet, 6 inches (Manhattan approach)
  • Length of main span: 1,595 feet, 6 inches
  • Number of supporting cables: 4
  • Diameter of  each cable: 15 ½ inches
  • Ultimate strength of a cable: 11,200 tons
  • Weight of each cable: 3,272 tons

Alexandre Gustave Eiffel (1832 – 1923)

  • He was born in Dijon France in 1832.
  • Later, he graduated from the Ecole Centrale des Arts et Manufactures, Paris in 1855 and joined a Belgian firm which specialized in railway equipment.
  • He established an independent practice in 1864 after which he established a career as an engineer-contractor.
  • Eiffel was a master of elegantly constructed wrought-iron lattices.
  • The structures that Eiffel designed had great social, economical, and political impact on the world. These structures include the Eiffel Tower, the Panama Canal, and the Statue of Liberty.

Eiffel’s Projects:

  • The Statue of  Liberty, 1884.
  • The Eiffel Tower, Paris, 1889.
  • The Panama Canal, 1904 – 1914 .

The Eiffel Tower, Paris, 1889:

  • It was built for the Paris World’s Fair of 1889.
  • This metal skeletal structure of 15,000 metal parts has both rectilinear and curvilinear ornamentation in iron.
  • Eiffel designed it as a cross-braced latticed girder with minimum wind resistance.
  • Constructed from over 6300 metric tons of highest quality wrought iron, it is a masterpiece of wrought-iron technology.

 The Panama Canal, 1904 – 1914:

  • Panama Canal, canal across the Isthmus of Panama, in Central America, that allows vessels to travel between the Pacific and Atlantic oceans.
  • The waterway measures 64 km, including dredged approach channels at each end.
  • The canal’s 12 locks (3 sets of double locks at each end) have the same dimensions: 33.5 m (110 ft) wide by 305 m (1,000 ft) long.
  • The gates at each end are 2.1 m (7 ft) thick.

Pier Luigi Nervi (1891 – 1979)

  • He was born June 21, 1891, in the Italian Alps town of Sondrio, Italy.
  • Nervi studied in the Civic Engineering School at the University of Bologna and joined the army engineering corps following the entanglement of Italy in World War I.
  • After the war was over, he joined a group called “The Society for Concrete Construction” and later established his own firm in 1920.
  • It was not until after Nervi left the group in 1923 that his unique approach to building garnered critical attention.

A builder and designer of new forms

  • “..searching for solutions that were intrinsically and when constructed the most economic.”
  • Primarily an engineer and technician, not an architect
  • Strove primarily for “strength through form.”
  • Maintained that the strong aesthetic appeal of his buildings was simply a by-product of their structural correctness.
  • The ceiling are the most awe inspiring part of his structures, described in words like “sunburst” and “lacework” (or the more technical cantilevered roof trusses and lamella vault)
  • He combined technical expertise, intuition, pragmatism, and a material of his own invention- “ferro-cemento”- to achieve structural beauty in a tradition of Italian design.

Nervi’s Projects:

Vaults:

  •  Air Force Hangar I, 1936.
  • Salone Agnelli B, Turin, 1949.

Domes:

  • Palazzetto dello Sport, Rome, 1959

 Palazzetto dello Sport, Rome, 1959:

  • The innovative dome is made of ribbed reinforced concrete.
  • Continuous windows circle around the arena under the dome.

Robert Maillart (1872 – 1940)

  • Robert Maillart, a Swiss engineer, was renowned for his inventive and beautiful reinforced-concrete bridges.
  • Maillart’s basic structural principles—integration of the supporting arch, the stiffening wall, and the traffic platform into one cohesive unit—were applied as early as 1901 in a bridge at Zuoz, Switzerland.
  • Robert Maillart had an intuition and genius that could entirely exploit the aesthetic of concrete.
  • He designed three-hinged arches in which the deck and the arch ribs were combined to produce closely integrated structures that evolved into stiffened arches of very thin reinforced concrete and concrete slabs.
  • These designs went beyond the common boundaries of concrete design in Maillart’s time.

“I remember seeing many old buildings in my hometown when I was young. Few of them were important buildings. They were mostly very simple, but very clear. I was impressed by the strength of these buildings because they did not belong to any epoch. They had been built there for over a thousand years and were still impressive and nothing could change that. All great styles passed, but…they were still as good as on the day they were built.”           – Mies Van Der Rohe.

Joseph Urban and Norman Foster – Hearst Magazine Building

Description

  • It is the world headquarters of the Hearst magazine Corporation
  • Architect – Joseph Urban, Tower – Sir Norman Foster
  • Location – 951-969 Eighth Ave at W47 , near Columbus Circle.
  • Date – 1928, tower 2006.
  • Construction – stone
  • Type – Office Building

The tower

  • Architect-  Norman Foster
  • Construction – Turner construction
  • 46 stories tall, standing 182 m (597 ft) with 80,000 m² (856,000 ft²) of office space.
  • Hearst Tower was the first skyscraper to break ground in New York City after September 11, 2001

About the building:

  • History – A blend of classicism and modernism
  • The former six-story headquarters building was commissioned by the founder, William Randolph Hearst and awarded to the architect Joseph Urban.
  • The building was completed in 1928 at a cost of $2 million and contained 40,000 sq. ft.
  • Originally built as the base for a proposed skyscraper, the construction of the tower was postponed due to the Great Depression.
  • The new tower addition was completed nearly eighty years later
  • A new modernist skyscraper got proposed on the same site in year 2000

Features

  • Late modernist concept of Space, geometry and light
  • Neutral grid
  • Structure is used as an ornament
  • Foster’s design preserves the six-story façade of the landmark
  • From its hollowed-out core rises a geodesic-like office tower featuring triangular steel bracing from the 10th floor up.
  • It will have no vertical columns around the perimeter, creating corner views that are not possible in a typically framed building.
  • Diagrid  form termed as the ‘birds’ mouths.’ They open up most of the floors and allow a much more panoramic view
  • Win Win Situation

As it is situated above the subway, the project also had to go through the Uniform Land Use Review Procedure. In the end, in exchange for improvements to the subway station—including a new entrance, installing three elevators and adding moving stairwells—Hearst was given a bonus of six floors to add onto the tower.

Diagrid Pattern:

  • Triangular bracing on the perimeter of a skyscraper is not new. It has been done before, most notably for the John Hancock Building in Chicago.
  • “The triangular frames carry the gravity load and has inherent strength and resistance to the lateral loads, seismic and wind
  • The triangles are so efficient in terms of bearing both the gravity and lateral loads, the building  use 21 percent less steel (9,500 metric tons) than a conventional building of its size.

Green Features

  • Hearst Tower is the first green building completed in New York City
  • The floor of the atrium is paved with heat conductive limestone.
  • Polyethylene tubing is embedded under the floor and filled with circulating water for cooling in the summer and heating in the winter.
  • Rain collected on the roof is stored in a tank in the basement for use in the cooling system, to irrigate plants and for the water sculpture in the main lobby.
  • The building was constructed using 80% recycled steel. Overall, the building has been designed to use 25% less energy than the minimum requirements for the city of New York
  • No use of materials, coatings and adhesives that emit volatile organic compounds — known as V.O.C.’s
  • Glass in the building have a coating that tends to admit visible light while reflecting a large part of the invisible solar radiation that causes heat.
  • Light and motion sensors are installed as well, to turn off lights when people are absent or when there is enough natural light coming the glass outer wall that artificial lighting is not needed.
  • Earned a gold designation from the USGBC LEED certification program.

Entering from the existing arch it opens up and what one see is

  • Three escalators in front to the third floor level.
  • Those escalators are set into a sloping water sculpture, which will cascade down past one as goes up.
