HISTORY OF CIVIL ENGINEERING It is difficult to determine the history of emergence and beginning of civil engineering, however, that the history of civil engineering is a mirror of the history of human beings on this earth. Man used the old shelter caves to protect themselves of weather and harsh environment, and used a tree trunk to cross the river, which being the demonstration of ancient age civil engineering. Civil Engineering has been an aspect of life since the beginnings of human existence. The earliest practices of Civil Engineering may have commenced between 4000 and 2000 BC in Ancient Egypt and Mesopotamia (Ancient Iraq) when humans started to abandon a nomadic existence, thus causing a need for the construction of shelter. During this time, transportation became increasingly important leading to the development of the wheel and sailing. Until modern times there was no clear distinction between civil engineering and architecture, and the term engineer and architect were mainly geographical variations referring to the same person, often used interchangeably. The construction of Pyramids in Egypt (circa 2700-2500 BC) might be considered the first instances of large structure constructions. Around 2550 BC, Imhotep, the first documented engineer, built a famous stepped pyramid for King Djoser located at Saqqara Necropolis. With simple tools and mathematics he created a monument that stands to this day. His greatest contribution to engineering was his discovery of the art of building with shaped stones. Those who followed him carried engineering to remarkable heights using skill and imagination. Ancient historic civil engineering constructions include the Qanat water management system (the oldest older than 3000 years and longer than 71 km,) the Parthenon by Iktinos in Ancient Greece (447-438 BC), the Appian Way by Roman engineers (c. 312 BC), the Great Wall of China by General Meng T’ien under orders from Ch’in Emperor Shih Huang Ti (c. 220 BC) and the stupas constructed in ancient Sri Lanka like the Jetavanaramaya and the extensive irrigation works in Anuradhapura. The Romans developed civil structures throughout their empire, including especially aqueducts, insulae, harbours, bridges, dams and roads. 1 Other remarkable historical structures are Sennacherib's Aqueduct at Jerwan built in 691 BC; Li Ping's irrigation projects in China (around 220 BC); Julius Caesar's Bridge over the Rhine River built in 55 BC, numerous bridges built by other Romans in and around Rome(e.g. the pons Fabricius); Pont du Gard (Roman Aqueduct, Nimes, France) built in 19 BC; the extensive system of highways the Romans built to facilitate trading and (more importantly) fast manoeuvring of legions; extensive irrigation system constructed by the Hohokam Indians, Salt River, AZ around 600 AD; first dykes defending against high water in Friesland, The Netherlands around 1000 AD; El Camino Real - The Royal Road, Eastern Branch, TX and Western Branch, NM (1500s AD). 2 Machu Picchu, Peru, built at around 1450, at the height of the Inca Empire is considered an engineering marvel. It was built in the Andes Mountains assisted by some of history’s most ingenious water resource engineers. The people of Machu Picchu built a mountain top city with running water, drainage systems, food production and stone structures so advanced that they endured for over 500years. A treatise on Architecture, Book called Vitruvius' De Archiectura, was published at 1AD in Rome and survived to give us a look at engineering education in ancient times. It was probably written around 15 BC by the Roman architect Vitruvius and dedicated to his patron, the emperor Caesar Augustus, as a guide for building projects. Throughout ancient and medieval history most architectural design and construction was carried out by artisans, such as stonemasons and carpenters, rising to the role of master builder. Knowledge was retained in guilds and seldom supplanted by advances. Structures, roads and infrastructure that existed were repetitive, and increases in scale were incremental. One of the earliest examples of a scientific approach to physical and mathematical problems applicable to civil engineering is the work of Archimedes in the 3rd century BC, including Archimedes Principle, which underpins our understanding of buoyancy, and practical solutions such as Archimedes’ screw. Brahmagupta, an Indian mathematician, used arithmetic in the 7th century AD, based on Hindu-Arabic numerals, for excavation (volume) computations. 3 CIVIL ENGINEERING DURING THE 18TH AND 19TH CENTURIES It was not until the 18th century that the term “civil engineering” was coined. The first civil engineering school was opened in 1747 in France. It was called The National School of Bridges and Highways. The first self-proclaimed civil engineer was a man named John Smeaton. Smeaton would eventually form the Smeatonian Society of Civil Engineers, who acted as leaders in the profession. And although this was more a social society than a technical group, the networking, and conversation that took place there influenced the design and construction of more than a few buildings of the 18th century. It was not until 1818 in London that the world’s first engineering society was set up as the Institution of Civil Engineers. It was in 1828 that the Institution of Civil Engineers received a Royal Charter and formally recognized civil engineering as a profession. Here is what the charter said: Civil engineering is the application of physical and scientific principles, and its history is intricately linked to advances in understanding of physics and mathematics throughout history. Because civil engineering is a wide ranging profession, including several separate specialized sub-disciplines, its history is linked to knowledge of structures, material science, geography, geology, soil, hydrology, environment, mechanics and other fields. HISTORY OF CIVIL ENGINEERING IN THE PHILIPPINES The history of the architecture and civil engineering profession in the Philippines were almost synonymous to each other. In more than three-and-a-half centuries of Spanish subjugation, there were no Filipino civil engineers. Social prejudice constrained the repressed indio builders to content themselves to be called mere Maestro de Obras (Master Builders) even if they could design and build any type of structure that technology could allow at that time. Master Builders as of today were equivalent to Construction Foreman. Civil Engineering, as practiced in the Philippines during the Spanish era, was not by virtue of an academic title. There were no civil engineering schools in the country at that time and the only architects/engineers with academic degrees were Spaniards. The walled city in Intramuros was established by the Spaniards as a model community. The Friar Architects/Engineers during that time were the ones who built the government buildings, bridges, residential and other structures, incorporated European standards in engineering and architectural installations. During the 18th and 19th centuries, Filipino engineers were assigned the task of maintaining, repairing and/or remodelling infrastructure systems in all pueblos or towns including churches, convents and government buildings. Maestro de Obras were called by the Ilustrados or the elite group to build structures in villas and mansions. 1571 Miguel Lopez de Legaspi founded the City of Manila on June 24, 1571 The Spaniards started building Fort Santiago (Fuerte de Santiago) after the establishment of the city of Manila under Spanish rule on June 24, 1571. 4 The fort has a perimeter of 2,030 feet (620 m), and it is of a nearly triangular form. The fort is one of the most important historical sites in Manila. Several lives were lost in its prisons during the Spanish Empire and World War II. José Rizal, one of the Philippine national heroes, was imprisoned here before his execution in 1896. 1584 Fort San Antonio Abad was built. It was captured by the British in 1762 and rebuilt at the beginning of the nineteenth century, when it was called La Polvorista because it was used as powder magazine. 1599 St. Augustine Church is the oldest stone church in the Philippines. Plans were approved in 1586. Construction started in 1587 and completed in 1607. It is an immense structure of thick walls of Corinthian and Ionic designs. It has withstood many earthquakes from 1645 up to the present and survived the British invasion in 1762, the Spanish–American War in 1898 and the Japanese invasion in 1942. 1621 In 1621, Don Bernardino Castillo, a generous patron and a well-known devotee of St. Sebastian, Patron of Archers, donated his lot, which is now the present site of the San Sebastian Church. The original church, which was made of wood, was burned in 1651 during a Chinese uprising. The succeeding structures were destroyed twice by fire and an earthquake in 1859, 1863, and 1880 respectively. Father Esteban Martinez, the parish priest at that time, approached the Spanish Architect Genero Palacios with a plan to build a fire and earthquake-resistant church made entirely of steel. Ambeth Ocampo states that the present San Sebastian church was ordered knockdown in steel parts from Brussels, Belgium. Two Belgian engineers supervised the construction of the church. On June 12, 1888, the first shipments of steel parts were brought to the Philippines. For two years, the church was assembled with local artists and craftsmen joining the Belgian firm in applying the final finishing touches on this new church of steel. The stained-glass windows were imported from the Henri Oidtmann Company, a German stained-glass firm. The engineering technique used in the construction of the church, including metal fixtures and the overall structure, were from Gustave Eiffel, the creator of the Eiffel Tower. This was confirmed when Chinese-American architect, I. M. Pei, visited the Philippines in the late 70’s. He came to confirm what he heard about Gustave Eiffel designing a steel church in Asia. 5 1632 Puente Grande was the first bridge to be erected across the grand Rio del Pasig. Built in 1632, this wooden bridge connects Intramuros and Binondo together, making it easier and relatively faster to travel from one end to the other. It underwent several reconstructions and renovations as it was always heavily damaged by earthquakes. After the 1863 earthquake, Puente Grande was renamed to Puente de España. The bridge was replaced in 1875 widening its spans to masonry of six and two central houses. It can accommodate both pedestrians and vehicles including horse or carabao drawn carts and carriages, and tranvia. This bridge was replaced for the last time with a neo-classical design by Juan Arellano in the 1930s, and was called the Jones Bridge. 1686 IRRIGATION AND WATER SYSTEM The first artesian wells were built in Betis, Pampanga by Fr. Manuel Camanes. The water system in Manila (now Metropolitan Waterworks and Sewerage System) had its beginning from the water works constructed by Fr. Juan Peguero in 1686. The first irrigation system was constructed in Tanay, Rizal by Fr. Jose Delgado. 1846 The Pasig River Light House was the first lighthouse (masonry-built) erected in the Philippines. It was first lighted on 1846 and deactivated on 1992. It was then located on the north jetty at the mouth of Pasig River, (San Nicolas, Manila) marking the entrance to the river for vessels around Manila Bay, looking to dock on the ports along the banks of the river in Manila. The lighthouse was demolished in 1992 and was replaced with an architecturally simpler lighthouse with the new tower built on the foundation of the old one. The Philippine Coast Guard Station of Manila is located adjacent to the lighthouse and the community that developed from the reclaimed lands is now known as "Parola" (Filipino for "lighthouse"). The present tower is a white conical concrete structure with a height of 46 feet (14.02 m) and a focal plane of 43 feet (13.11 m). The old tower was taller at 49 feet (14.94 m). Lighthouses in the Philippines are maintained by the Philippine Coast Guard. 1852 Puente Colgante (which is the term for a suspension bridge in Spanish; literally, hanging bridge) was the first suspension bridge built in Southeast Asia when it was started in 1849 and completed in 1852. It was built and owned by Ynchausti y Compañia, the business headed by Jose Joaquin de Ynchausti. He commissioned the 6 design from Basque engineer Matias Menchacatorre. The bridge was first named Puente de Claveria, likely in honor of the Governor-General of the Philippines Narciso Clavería, who served from 1844-1849. Puente Colgante was the first suspension bridge, not only the Philippines but in South East Asia as well, and, probably the first toll bridge of its kind in the Philippines, a precursor of the modern Sky Way, albeit for pedestrian use only. The suspension bridge measured 110 metres (360 ft) long and 7 metres (23 ft) wide, and had two lanes that allowed passage of horses and carabao-drawn carriages. It was also opened for pedestrians traveling on foot between Quiapo and Intramuros and nearby areas. In 1854, Ynchausti brought together the Ynchausti family holdings under the above name. A Basque Spaniard born in Cadiz, de Ynchausti immigrated to the Philippines in the second quarter of the nineteenth century and built a business empire. In 1889, Ynchausti y Compañia was the largest company in the Philippines. The 20th-century writer Nick Joaquin described the bridge as it was in the 1870s: “Across the city’s river now arched & the amazing Puente Colgante, suspended in the air, like a salute to the age of science and engineering. The Industrial Age found its expression in the Philippines in the form of a bridge unparalleled throughout Asia.” 1867 The project for public supply of fresh water to the city dates from the early 18th century. Before this, the city had to be content with a fresh water supply based on cisterns. In 1867, the town council decides to take on the challenge of a project to supply fresh water to the whole of the city. In 1882, the first public water fountain gushed forth its waters, and shortly after this, the technology of the times was successful in providing Manila with a fresh water supply from sources up-river. The Carriedo Fountain was built in May 1882 as part of the Carriedo water works system and was inaugurated by Governor-General Fernando Primo de Rivera on July 24, 1882. 1868 It was in 1868 when the Bureau of Public Works and Highways (Obras Publicas) and Bureau of Communications and Transportation (Communicationes y Meteologia) were organized under a civil engineer known as “Director General”. 1878-1918 The Founding of Carriedo Waterworks Manila didn’t get running water until 1878, when the municipal waterworks was established by Governor Domingo Moriones, with money from a fund that by then had become legendary as the Carriedo Legacy. A “publicspirited citizen”, Don Francisco Carriedo y Peredo was a Basque who during his life conferred immense benefits on the Philippines, having migrated in the Philippines early in the 18th century. One of his “obras pias” (pious works), was a legacy he left in his will for the building of a Manila water system. Though Señor Carriedo did not live long enough to see his legacy since he died in 1743, Manila was to be without running water for more than a 7 century longer. Thanks to Governor Moriones who acted on providing Manila with running water that the Carriedo Legacy was finally fulfilled. 1875 On June 25, 1875, King ALFONSO XII of Spain promulgates the Royal Decree directing the Office of the Inspector of Public Works of the Philippines to submit a general plan of railroad in Luzon. 1876 The General Plan for Railways was drawn up in 1876 for the island of Luzon, and included a network totalling 1,730 kilometers. A 195.4 km. stretch of track was constructed between Manila and Dagupan. This operated a regular service as from 1892. The most outstanding works carried out on the railway system were the bridge over the great Pampanga River and the building of Tutubán Station, in the Tondo district. The tremendous growth of the city of Manila led the administration to contemplate, in 1878, the setting up of a public transport network. 1878 The concession for constructing five tramways in Manila and its suburbs was approved. The plan included a main station at San Gabriel and the crossing of the river via the "Puente de España" 1880 School for Maestro de Obras called Escuela Practica y Artes Oficios de Manila was founded. Its first Filipino graduates were Julio Hernandez (1891), Isidro Medina (1894), Arcadio Arellano (1894) and Juan Carreon (1896). Puente de Convalecencia or better known as the Ayala Bridge was completed in 1880. Originally it is composed of two separate spans connected by the Isla de Convalecencia, which is home to Hospisio de San Jose, dropping point for abandoned babies, the bridge over this island was originally made of wooden arched trusses. 1887 On July 31, 1887, construction of the ManilaDagupan railroad was started 1892 On November 24, 1892, the entire line from Manila to Dagupan, with a total length of 195.4 kms, was completed and put into commercial operations. 8 Road work in the Philippine Islands during the eighteenth and nineteenth centuries, under the Spanish regime, consisted in the opening of routes of communication throughout the Islands, in a very thorough manner, and leaving a very valuable asset to the present Government in the matter of the width of right of way, which was incorporated into the law and became a part of the public domain. The location of these routes has been justified, inasmuch, that few changes have been made in the general alignment, except when new sections have opened up and a change in location justified. Grades have been improved and method of construction changed. The right of way, as established by law, has made possible the construction methods of today. Two types of construction under Spanish regime were practiced: First, pavement of cut spanish road, cut adobe stone pavement. This was usually of the adobe quality, probably used because it is easily quarried, cut, and handled, the size used called ''ordinario" 20 by 20 centimeters and 50 centimeters long. This makes a very smooth and pretty pavement, but, where an ordinary amount of traffic is encountered, wears very rapidly. Second, rubble-stone pavement, cobblestones. The pavement of cobblestone consisted of boulders probably taken from river beds varying in size from 10 to 30 centimeters in diameter. This type was very durable and lasting, so long as the individual stones retained their position in a bed of earth. Owing to the size used there was no bond, and stones were easily displaced, unless covered with earth, sand, or gravel. This pavement was very rough and, had a second or top course of small gravel been used and bound together with a binding material, would have been in use today. 1898 The Organic Decree issued by Gen. Emilio Aquinaldo establishing the Philippine Revolutionary Government created four (4) government departments among which was the Department of War and Public Works. Though once included in the Department of War, now Department of National Defense, its functions as builder and maintainer of roads, bridges and other public works structures are inherent in the present Department. The inclusion of public works in the War and Department can be explained by the exigencies of the revolutionary period. The construction of fortifications and trenches was needed in the cause for freedom which our heroes had fought for. When Spain ceded the Philippines to the United States in 1898, the public works and activities were placed under the U.S. Army engineers. 1899 The Malolos Constitution was ratified during a general assembly of Congress, and the first Council of Government of the First Philippine Republic was created. From January 21, 1899 to May 7, 1899, with Apolinario Mabini as President of the Cabinet (i.e. Prime Minister), Gracio Gonzaga served as the Secretary of Public Welfare, which included the transportation and communications portfolio. When Mabini was replaced by Pedro Paterno as President of the Cabinet, among the seven departments set up was the Communicaciones y Obras Publicas (i.e. the Communications and Public Works Department). Maximo Paterno was appointed as Secretary of Public Works and Communications. Since then, Public Works, Transportation, and Communications have been grouped into one department. The coming of the Americans brought about drastic changes in our engineering culture. The new colonizers pursued “benevolent” policies that focused on English education, public health, free enterprise, and representative governance thus bringing with them were military engineers, Thomasite teachers, doctors and evangelist. Highways, bridges, schools, hospitals, and government buildings steadily transformed the Philippine landscape. 9 1899 In his letter dated January 4, 1899 to Filipinos, US Major-General Elwell S. Otis, the Military Governor of the Philippines, announced US President William McKinley’s instructions for the islands’ Benevolent Assimilation. The instructions stated that the management of public property and revenue, and the use of all public means of transportation, were to be conducted by the military authorities (i.e. by the US Army) until such time that they would be transferred back to civilian authority. Thus, the Bureau of Engineering was placed under the supervision of American military engineers. The ports were opened to commerce for all foreign nations. 1900 Foundation of the Liceo de Manila, a private institution offering academic course for maestro de obras and headed by Leon Ma. Guerrero. The first private school to offer an academic title for Maestro de Obras (the forerunner of formal education in architecture/engineering). The introduction of reinforced concrete in the Philippines was in the 1900s and its use in the construction of the Masonic Temple (Grand Lodge of the Philippines), the first multi-structure in Escolta, Manila. Early 1900’s Transportation in the Philippines was depended largely on trails, waterways, railroad, earth roads and partially-gravelled roads. Highway in the Philippines at that time is nothing more than a dream to most Filipinos. The US government initiated the development of roadways in the Philippines connecting towns, cities and provinces. The popular Macadam road type was introduced. It gained acceptance because of abundant supply of stones and gravel. 10 1909 Wawa Dam (also known as Montalban Dam) is a gravity dam constructed over the Marikina River in the municipality of Rodriguez in Rizal province, Philippines. The slightly arched dam is situated in the 360-metre (1,180 ft) high Montalban Gorge or Wawa Gorge, a water gap in the Sierra Madre Mountains, and east of Manila. It was built in 1909 during the American colonial era to provide the water needs for Metro Manila. It used to be the only source of water for Manila until Angat Dam was built and Wawa was abandoned. Due to insufficiency of water supply for Metro Manila, there was a strong clamor to reuse the dam. 11 12 13 1940 Highway 54 was the former name of the Epifanio delos Santos Avenue (EDSA). Stretching some 54 kilometers, Highway 54 serves as a lifeline for hundreds of thousands of Filipinos passing or doing business in Metro Manila. 14 1942 On Philippine soil, to mitigate the sufferings of the people under the iron-clad rule of the Japanese, the Philippine Executive Commission was established. Under President Jose P. Laurel’s administration,Quintin Paredes served as Minister of Public Works and Communications. Caliraya Dam is an embankment dam located in the town of Lumban province of Laguna, in the Sierra Madre Mountain Range of the Philippines. The reservoir created by the dam, Lake Caliraya, initially supplied one of the oldest hydroelectric plants in the Philippines, and later became a popular recreational area for numerous water sports and fishing. The dam construction was started in 1939 and a small hydroelectric plant was operated in 1942. After the Second World War, the new independent Philippine government continued the rehabilitation and construction of roads, bridges, buildings and other infrastructures, through the reparations and war damages paid by the Japanese government. Other financial grants and aids received from the US government were used in the construction and rehabilitation of roads, bridges, buildings and other infrastructures. 15 1950-1956 The Ambuklao dam was the highest and biggest in the Far East. It is made of earth and rockfill which measures 129 meters in height and 452 meters in length. The elevation of its crest is 758 meters and the roadway that runs through the top of the dam has an elevation of 756 meters. The gross storage capacity of the dam's reservoir is 327,170,000 cubic meters and it has a usable storage capacity of 258,000,000 cubic meters. Construction began on July 1950 and opened on December 23, 1956. 16 17 18 1961-1967 Angat Dam located at Norzagaray, Bulacan started its construction on November 1961 and opened on October 16, 1967 with height of 131 meters, length of 568 meters and base width of 550 meters. The source of dam is the Angat River, with a capacity of 850 million cubic meters 19 20 21 22 23 24
