History of Civil Engineering Civil Engineering in Ancient Times The history of civil engineering reflects human progress, beginning with early humans using natural materials like tree trunks and shelter caves for protection and crossing rivers. Civil engineering began to take shape as civilizations developed in ancient Egypt, Mesopotamia, and the Indus Valley. In Egypt, engineers built monumental structures like the pyramids (circa 2700-2500 BCE) and developed sophisticated irrigation systems along the Nile River. Imhotep, the first documented engineer, designed the Stepped Pyramid of Djoser around 2630-2610 BCE, pioneering the use of shaped stones in construction. And after 40-70 years later, the Pyramids of Giza, built between 2589 and 2504 BCE. Other ancient engineering feats include Persia's Qanat water management system, the Parthenon in Greece, and the Appian Way in Rome. The Romans (500 BCE - 500 CE) perfected the arch, enabling the construction of extensive road networks, aqueducts, and iconic buildings like the Pantheon and Colosseum, using concrete and stone. During the Medieval Period (500 CE - 1500 CE), civil engineering focused on fortifications, castles, and bridges, exemplified by structures such as the Tower of London (11th century). The rise of Gothic architecture in the 12th century brought innovations like pointed arches and buttresses, allowing for the construction of grand cathedrals such as Notre Dame and Chartres. Vitruvius’ De Architectura, written around 15 BCE, remained influential as a guide for building projects, emphasizing the principles of strength, functionality, and beauty. Civil engineering formally emerged in France in 1716 with the establishment of the Bridge and Highway Corps and the École Nationale des Ponts et Chaussées ("National School of Bridges and Highways"). The school’s instructors authored books that became foundational texts on the mechanics of materials, machines, and hydraulics, prompting leading British engineers to learn French to study them. In 1747, Jean-Rodolphe Perronet founded the École des Ponts et Chaussées, one of the earliest engineering schools in Europe, where he served as its first director. As design and calculation began to replace traditional rule-of-thumb methods, non-military engineers gained prominence. Skilled craftsmen, such as millwrights and toolmakers, transitioned into civil engineering, including figures like James Brindley, who began as a millwright and became the leading canal builder of the 18th century, and John Rennie, who started as a millwright’s apprentice and later constructed the new London Bridge. Another prominent engineer, Thomas Telford, originally a stonemason, rose to become Britain’s foremost road builder. John Smeaton, widely regarded as the father of civil engineering, was the first to formally adopt the title of civil engineer. Originally an instrument maker, Smeaton designed the Eddystone Lighthouse and founded the Society of Civil Engineers in 1771 to promote public works like canals and railways. The Society’s meetings were held during parliamentary sessions, and its legacy continues today. Key advancements in civil engineering have significantly shaped the field, beginning with the development of reinforced concrete by Joseph Monier in 1867. This innovation allowed engineers to construct stronger, more flexible structures capable of withstanding greater loads, becoming a cornerstone of modern construction, especially for high-rise buildings and bridges. Later, Karl Terzaghi’s introduction of soil mechanics in the early 20th century revolutionized foundation design by enabling engineers to better understand how soils behave under different conditions, ensuring greater stability for taller skyscrapers, long-span bridges, and other large infrastructure projects. Building on these foundations, the 20th and 21st centuries saw the rise of groundbreaking megaprojects such as the Hoover Dam, Panama Canal, and Burj Khalifa, which pushed engineering to new limits. These projects exemplified how engineers could tackle immense technical and environmental challenges through the integration of massive scale, complexity, and innovation. The advent of computer-aided design (CAD) and finite element analysis (FEA) further transformed the field by allowing engineers to model and simulate complex structures with precision. This shift from manual drafting to digital tools enabled the design of intricate, large-scale projects with enhanced safety and efficiency. History of Civil Engineering in the Philippines The history of civil engineering in the Philippines is closely intertwined with its architectural development, particularly during the Spanish colonial period. For over three centuries, Filipino civil engineers were known as Maestro de Obras (Master Builders), similar to modern-day construction foremen. At that time, civil engineering was not yet recognized as an academic profession, with only Spaniards holding formal engineering degrees, while Filipino builders maintained and remodeled existing infrastructure. After the establishment of the First Philippine Republic in 1898, the Department of War and Public Works was created, signaling the growing importance of public works in governance. Over time, civil engineering schools and professional organizations have evolved, leading to the formal recognition and professionalization of civil engineering in the Philippines. In the 21st century, civil engineering has increasingly embraced sustainability due to rising concerns about environmental degradation and climate change. Engineers are now focusing on designing infrastructure that reduces energy consumption and minimizes environmental impacts. This includes the use of renewable energy sources like solar and wind in projects, as well as eco-friendly materials and methods in construction. Green building techniques, such as energy-efficient designs and sustainable urban planning, are becoming the norm, ensuring that infrastructure not only serves its immediate purpose but also contributes to long-term environmental protection and resilience against climate-related challenges.  CIVIL ENGINEERING AND SOCIETY AND OTHER PROFESSIONS W/ SOCIETY INTRODUCTION The word “Civil” stands for Civilization which means development. Hence, Civil Engineers deal (Design and Execute) with projects which are related with the development of the society or an area to an advanced stage. Civil engineering is one of the oldest disciplines and industries in the world. Civil engineering deals with conceptualizing, designing, constructing, and maintaining a physical environment that includes various types of infrastructures. They design, build, and maintain the foundation for our modern society, which includes buildings, railways, road and bridges, sewage, drinking water, and energy systems like dams, seaports and airports, infrastructures for a cleaner environment, and many more. Evidently, a civil engineer has a significant impact on the things we use daily and the things we observe in our surroundings. W/ OTHER PROFESSIONS INTRO: PROFESSIONS that Civil Engineers work with: Architects plan and design houses, factories, office buildings, and other structures. Civil help civil engineers to plan, design, and build Engineering highways, bridges, utilities, and other Technicians infrastructure projects. They also help to plan, design, and build commercial, industrial, residential, and land development projects. Construction plan, coordinate, budget, and supervise Managers construction projects from start to finish.  Environmental use the principles of engineering, soil Engineers science, biology, and chemistry to develop solutions to environmental problems. Landscape design parks and the outdoor spaces of Architects campuses, recreational facilities, businesses, private homes, and other open areas. Mechanical - design, develop, build, and test mechanical Engineers and thermal sensors and devices, including tools, engines, and machines. Surveyors make precise measurements to determine property boundaries. Urban and develop land use plans and programs that Regional help create communities, accommodate Planners population growth, and revitalize physical facilities in towns, cities, counties, and metropolitan areas.
