The Anghel Saligny Bridge (formerly King Carol I Bridge) is a complex of two railroad truss bridges in Romania, across the Danube River and the Borcea branch of the Danube, connecting the regions of Muntenia and Dobruja. The bridge is listed in the National Register of Historic Monuments.

It rises 30 metres above the surface of the Danube, it spans 4,087.95 metres (13,411.9 feet), of which 1,662 over the river, and at the time when it was built

it was Europe’s longest bridge and the third longest in the world. Its Cernavodă foot is flanked by the impressive statues of two “dorobanţi” (infantry soldiers) which stand as mementos of Romania’s Independence War. Designed by the French sculptor Léon Pilet and partly paid for by the French Embassy to honour King Charles I, the dorobanţi were cast in bronze in three pieces in Lyon, then transported to and assembled on the bank of the Danube.

History of construction

/ civil engineering profession:

Engineering has been an integral part of human life since the beginning of human civilization. Civilization is thought to have begun in ancient Egypt and Mesopotamian civilization (ancient Iraq) in 4000 and 2000 BC, just when people felt the need to build habitats for their habitation.The discovery of wheels and sails at that time greatly increased the importance of communication.

construction engineering works:

Until recently, there was no clear distinction between civil engineering, architecture, and architecture. The Egyptian pyramids [2600-2500 BC] are considered to be the earliest examples of large structures in world history. Other notable civil works include the Kanat Water Management Strategy (the oldest being 3000 years ago and about 61 km long), The Azapen Way, the Ghetwal of China, etc. The Romans built numerous civil structures throughout their empire, including canals, harbors, bridges, dams, and roads. And these are now known as construction engineering work.

The Institute of Civil Engineers was established in London in 1818. In 1020, Thomas Telford was elected the first president. In 1828 the institution adopted the royal charter, which recognized civil engineering as a profession. In 1819, Norwich University became the first private college to teach civil engineering in the United States. In 1835, the first Ditheri in civil engineering was started in the United States from the Wrangley Polytechnic Institute. In 1905, Nor Stanton became the first woman to receive a degree in civil engineering from Connell University.

Different types of construction works:

Construction / Civil Engineering is one of the branches of professional engineering system, where design, construction engineering, practical or natural environment management is discussed, including construction of bridges, roads, ditches, dams, buildings etc. Basically, civil engineers work all over the world.Civil engineering is the oldest engineering system. With the evolution of time, civil engineering has been divided into different branches to ensure efficiency, quality and proper quality control of work.E.g.-

1. Construction engineering, 2. Environmental engineering 3. Geotechnical engineering, 8. Geophysics, 5. Structural engineering, 6. Earthquake engineering, 7. Transportation engineering, 8. Atmospheric science, 9. Water resources engineering, 10. Land survey, 11. Geology, urban and regional planning, 12. Infrastructure engineering,

And civil engineering and construction engineering are equally important in all public and private sectors.

Did you know? 🧐

Anghel I. Saligny, an academician, engineer, construction engineer, minister and teacher, is considered to be one of the pioneers of world technology in the designing and construction of bridges and silos with metal structure and reinforced concrete, one of the founders of Romanian engineering.

Between 1884 and 1889 he worked on the construction of the docks and warehouses in Galaţi and Braila, giving total original solutions, including: the construction of foundations on fascination layers and pile drivers, the connection basins with the Danube for silos and the use, for the first time in the world, reinforced concrete in silos construction.

Based on his own inventions, Anghel Saligny built for the first time the reinforced concrete silos from Braila (1888) and Galaţi (1889), only two decades after the French Joseph Monier (1823-1906) obtained in 1867 , the first patent for building elements (beams, slabs, pillars) of reinforced concrete, this material little studied at the time. The silos designed and executed, under the direct guidance of Anghel Saligny, could contain over 25,000 tonnes of grain (30 m x 120 m at the base and over 18 m tall). The hexagonal cell walls of the silos have been made, for the first time in the world, by plate-shaped pieces made to the ground. Prefabrication of floorboards, stiffening and junction corners, metal strip welding and assembly-based assembly are other global priorities.

His most important work is the design in 1888 and the construction of the Cernavoda Danube Bridge, which at that time was the longest in Europe and among the most important metallic openings in the world, between 1890 and 1895. Saligny's project brought two major innovations in the construction of bridges: the new beam system with consoles for the bridge superstructure and the use of soft steel instead of puddle iron as building material for bridge bridges.

Between the years 1889 and 1909 he headed the Constanta harbor works, introducing for the first time in Romania pilots and artillery dredgers in the port constructions and designing the grain silos and the oil station.
