Civil Engineering:
A civil engineer is a man or woman who practices civil engineering – the utility of planning, designing, constructing, maintaining, and working infrastructures whilst protecting the public and environmental health, as properly as enhancing current infrastructures that have been neglected.Civil engineering is a professional engineering discipline that deals with the design, construction, and protection of the bodily and naturally constructed environment, along with public works such as roads, bridges, canals, dams, airports, sewerage systems, pipelines, structural components of buildings, and railways.Civil engineering is one of the oldest engineering disciplines due to the fact it offers with constructed environment together with planning, designing, and overseeing building and preservation of building structures, and facilities, such as roads, railroads, airports, bridges, harbors, channels, dams, irrigation projects, pipelines, electricity plants, and water and sewage systems.The time period "civil engineer" used to be installed via John Smeaton in 1750 to contrast engineers working on civil tasks with the military engineers, who labored on armaments and defenses. Over time, a number of sub-disciplines of civil engineering have end up diagnosed and a lot of navy engineering has been absorbed by using civil engineering. Other engineering practices grew to become recognized as independent engineering disciplines, which includes chemical engineering, mechanical engineering, and electrical engineering.Civil engineering is traditionally damaged into a variety of sub-disciplines. It is considered the second-oldest engineering discipline after army engineering, and it is described to distinguish non-military engineering from military engineering. Civil engineering takes vicinity in the public sector from municipal through to national governments, and in the personal region from character homeowners through to international companies.

Most civil engineering today deals with power plants, bridges, roads, railways, structures, water supply, irrigation, environmental, sewer, flood control, transportation, telecommunications and traffic.

In essence, civil engineering can also be viewed as the profession that makes the world a more agreeable location in which to live.

Engineering has developed from observations of the methods herbal and built structures react and from the development of empirical equations that grant bases for design.

Civil engineering is the broadest of the engineering fields, partly due to the fact it is the oldest of all engineering fields.

In fact, engineering was once once divided into solely two fields, army and civil.

Civil engineering is still an umbrella term, comprised of many associated specialities.

In some places, a civil engineer may additionally perform land surveying; in others, surveying is restrained to building surveying, except an extra qualification is obtained.

Civil Engineer Education:
Civil engineers normally possess an educational degree in civil engineering. The size of study is three to five years, and the completed diploma is unique as a bachelor of technology, or a bachelor of engineering. The curriculum typically includes classes in physics, mathematics, undertaking management, format and unique topics in civil engineering. After taking simple publications in most sub-disciplines of civil engineering, they move on to specialize in one or extra sub-disciplines at advanced levels. While an undergraduate diploma (BEng/BSc) normally gives successful students with industry-accredited qualification, some educational institutions provide post-graduate stages (MEng/MSc), which allow students to similarly specialize in their particular area of interest.

Education and licensing:
In most countries, a civil engineer will have graduated from a post-secondary college with a degree in civil engineering, which requires a robust heritage in arithmetic and the bodily sciences; this diploma is typically a bachelor's degree, though many civil engineers study in addition to reap master's, engineer, doctoral and submit doctoral degrees. In many countries, civil engineers are situation to licensure. In some jurisdictions with mandatory licensing, humans who do no longer acquire a license may additionally no longer name themselves "civil engineers".

Civil Engineer History:
Civil engineering profession:
History Of Structural Engineering:
Engineering has been an thing of lifestyles on account that the beginnings of human existence. The earliest practice of civil engineering may have commenced between 4000 and 2000 BC in historic Egypt, the Indus Valley Civilization, and Mesopotamia (ancient Iraq) when people started out to abandon a nomadic existence, creating a want for the development of shelter. During this time, transportation grew to be an increasing number of necessary main to the improvement of the wheel and sailing.In the 18th century, the time period civil engineering used to be coined to comprise all matters civilian as opposed to navy engineering. The first self-proclaimed civil engineer used to be John Smeaton, who built the Eddystone Lighthouse. In 1771 Smeaton and some of his colleagues formed the Smeatonian Society of Civil Engineers, a crew of leaders of the profession who met informally over dinner. Though there was evidence of some technical meetings, it was little greater than a social society.In 1818 the Institution of Civil Engineers used to be established in London, and in 1820 the eminent engineer Thomas Telford became its first president. The organization obtained a Royal Charter in 1828, formally recognising civil engineering as a profession. Its charter described civil engineering as:
The art of directing the extremely good sources of energy in nature for the use and comfort of man, as the potential of production and of traffic in states, both for external and inside trade, as utilized in the building of roads, bridges, aqueducts, canals, river navigation and docks for inside intercourse and exchange, and in the development of ports, harbours, moles, breakwaters and lighthouses, and in the artwork of navigation via synthetic strength for the purposes of commerce, and in the development and utility of machinery, and in the drainage of cities and towns.

Until modern-day times there was once no clear difference between civil engineering and architecture, and the time period engineer and architect have been broadly speaking geographical variations referring to the identical occupation, and frequently used interchangeably. The building of pyramids in Egypt (circa 2700–2500 BC) were some of the first situations of large shape constructions. Other historic ancient civil engineering constructions consist of the Qanat water administration system (the oldest is older than 3000 years and longer than seventy one km,) the Parthenon by means of Iktinos in Ancient Greece (447–438 BC), the Appian Way by using Roman engineers (c. 312 BC), the Great Wall of China by using General Meng T'ien below orders from Ch'in Emperor Shih Huang Ti (c. 220 BC) and the stupas constructed in historic Sri Lanka like the Jetavanaramaya and the substantial irrigation works in Anuradhapura. The Romans developed civil structures throughout their empire, which includes especially aqueducts, insulae, harbors, bridges, dams and roads.

Civil engineering as a discipline:
Civil engineering is the software of physical and scientific principles for fixing the troubles of society, and its records is intricately linked to advances in the understanding of physics and arithmetic at some point of history. Because civil engineering is a wide-ranging profession, such as various specialised sub-disciplines, its history is linked to know-how of structures, substances science, geography, geology, soils, hydrology, environment, mechanics and other fields.

Throughout ancient and medieval records most architectural sketch and development was carried out by way of artisans, such as stonemasons and carpenters, rising to the position of grasp builder. Knowledge used to be retained in guilds and seldom supplanted by way of advances. Structures, roads, and infrastructure that existed were repetitive, and will increase in scale were incremental.

One of the earliest examples of a scientific method to bodily and mathematical issues relevant to civil engineering is the work of Archimedes in the third century BC, which include Archimedes Principle, which underpins our appreciation of buoyancy, and realistic options such as Archimedes' screw. Brahmagupta, an Indian mathematician, used arithmetic in the 7th century AD, based totally on Hindu-Arabic numerals, for excavation (volume) computations.

Practicing engineers:
In most countries, a bachelor's degree in engineering represents the first step toward professional certification, and a professional physique certifies the degree program. After completing a licensed degree program, the engineer need to fulfill a vary of necessities such as work ride and exam requirements earlier than being certified. Once certified, the engineer is targeted as a professional engineer (in the United States, Canada and South Africa), a chartered engineer (in most Commonwealth countries), a chartered professional engineer (in Australia and New Zealand), or a European engineer (in most nations of the European Union). There are global agreements between relevant professional our bodies to enable engineers to practice across country wide borders.

The benefits of certification range depending upon location. For example, in the United States and Canada, "only a licensed professional engineer might also prepare, sign and seal, and post engineering plans and drawings to a public authority for approval, or seal engineering work for public and personal clients." This requirement is enforced beneath provincial law such as the Engineers Act in Quebec. No such regulation has been enacted in different countries which include the United Kingdom. In Australia, country licensing of engineers is confined to the state of Queensland. Almost all certifying our bodies maintain a code of ethics which all participants should abide by.

Engineers need to obey contract regulation in their contractual relationships with different parties. In cases the place an engineer's work fails, they can also be concern to the law of tort of negligence, and in excessive cases, crook charges. An engineer's work should also comply with numerous other rules and policies such as constructing codes and environmental law.

Sub-disciplines:
There are a number of sub-disciplines inside the huge area of civil engineering. General civil engineers work carefully with surveyors and specialized civil engineers to design grading, drainage, pavement, water supply, sewer service, dams, electric and communications supply. General civil engineering is also referred to as website online engineering, a branch of civil engineering that principally focuses on converting a tract of land from one usage to another. Site engineers spend time touring undertaking sites, meeting with stakeholders, and getting ready construction plans. Civil engineers practice the standards of geotechnical engineering, structural engineering, environmental engineering, transportation engineering and development engineering to residential, commercial, industrial and public works tasks of all sizes and stages of construction.

Construction Engineering:
Construction engineering involves planning and execution, transportation of materials, site improvement primarily based on hydraulic, environmental, structural and geotechnical engineering. As development firms have a tendency to have higher business threat than other sorts of civil engineering corporations do, construction engineers often interact in extra business-like transactions, for example, drafting and reviewing contracts, evaluating logistical operations, and monitoring expenses of supplies.

Environmental Engineering:
Environmental engineering is the present day time period for sanitary engineering, although sanitary engineering historically had not protected lots of the hazardous waste management and environmental remediation work blanketed through environmental engineering. Public fitness engineering and environmental fitness engineering are different terms being used.

Environmental engineering offers with cure of chemical, biological, or thermal wastes, purification of water and air, and remediation of contaminated web sites after waste disposal or accidental contamination. Among the subjects covered by environmental engineering are pollutant transport, water purification, waste water treatment, air pollution, solid waste treatment, and hazardous waste management. Environmental engineers administer air pollution reduction, green engineering, and industrial ecology. Environmental engineers additionally bring together facts on environmental consequences of proposed actions.

Geotechnical Engineering:
Geotechnical engineering studies rock and soil assisting civil engineering systems. Knowledge from the discipline of soil science, substances science, mechanics, and hydraulics is applied to safely and economically sketch foundations, holding walls, and different structures. Environmental efforts to shield groundwater and safely keep landfills have spawned a new vicinity of research called geoenvironmental engineering.

Identification of soil houses offers challenges to geotechnical engineers. Boundary prerequisites are regularly well described in different branches of civil engineering, but not like steel or concrete, the fabric properties and behavior of soil are hard to predict due to its variability and drawback on investigation. Furthermore, soil well-knownshows nonlinear (stress-dependent) strength, stiffness, and dilatancy (volume trade associated with software of shear stress), making reading soil mechanics all the extra difficult. Geotechnical engineers frequently work with expert geologists and soil scientists.

Coastal Engineering:
Coastal engineering is worried with managing coastal areas. In some jurisdictions, the phrases sea protection and coastal protection imply protection against flooding and erosion, respectively. The time period coastal protection is the greater normal term, however coastal administration has emerge as more famous as the field has improved to methods that enable erosion to claim land.

Earthquake Engineering:
Earthquake engineering entails designing buildings to face up to hazardous earthquake exposures. Earthquake engineering is a sub-discipline of structural engineering. The fundamental targets of earthquake engineering are to understand interplay of structures on the shaky ground; foresee the penalties of viable earthquakes; and design, assemble and maintain structures to function at earthquake in compliance with constructing codes.

Forensic Engineering:
Forensic engineering is the investigation of materials, products, buildings or components that fail or do no longer operate or function as intended, causing private harm or injury to property. The penalties of failure are dealt with through the regulation of product liability. The field additionally deals with retracing approaches and tactics main to accidents in operation of vehicles or machinery. The problem is utilized most many times in civil law cases, although it may additionally be of use in criminal regulation cases. Generally the purpose of a Forensic engineering investigation is to come across motive or causes of failure with a view to improve overall performance or life of a component, or to assist a courtroom in figuring out the data of an accident. It can additionally involve investigation of intellectual property claims, in particular patents.

Materials Engineering:
Materials science is carefully associated to civil engineering. It studies critical traits of materials, and deals with ceramics such as concrete and mix asphalt concrete, sturdy metals such as aluminum and steel, and thermosetting polymers including polymethylmethacrylate (PMMA) and carbon fibers.Materials engineering entails safety and prevention (paints and finishes). Alloying combines two types of metals to produce another steel with desired properties. It comprises factors of applied physics and chemistry. With recent media interest on nanoscience and nanotechnology, materials engineering has been at the forefront of academic research. It is also an vital section of forensic engineering and failure analysis.

Structural Engineering:
Structural engineering is concerned with the structural diagram and structural analysis of buildings, bridges, towers, flyovers (overpasses), tunnels, off shore buildings like oil and gas fields in the sea, aerostructure and other structures. This includes identifying the masses which act upon a structure and the forces and stresses which arise within that structure due to those loads, and then designing the shape to successfully guide and face up to those loads. The hundreds can be self weight of the structures, other dead load, stay loads, shifting (wheel) load, wind load, earthquake load, load from temperature alternate etc. The structural engineer should design structures to be safe for their users and to successfully fulfill the characteristic they are designed for (to be serviceable). Due to the nature of some loading conditions, sub-disciplines inside structural engineering have emerged, inclusive of wind engineering and earthquake engineering.Design considerations will consist of strength, stiffness, and steadiness of the shape when subjected to loads which can also be static, such as furniture or self-weight, or dynamic, such as wind, seismic, crowd or automobile loads, or transitory, such as transient development loads or impact. Other issues encompass cost, constructability, safety, aesthetics and sustainability.

Surveying Engineering:
Surveying is the process by means of which a surveyor measures certain dimensions that happen on or near the floor of the Earth. Surveying tools such as levels and theodolites are used for accurate measurement of angular deviation, horizontal, vertical and slope distances. With computerisation, electronic distance size (EDM), whole stations, GPS surveying and laser scanning have to a massive extent supplanted usual instruments. Data collected with the aid of survey size is converted into a graphical representation of the Earth's surface in the structure of a map. This data is then used with the aid of civil engineers, contractors and realtors to format from, construct on, and trade, respectively. Elements of a shape need to be sized and placed in relation to each other and to website boundaries and adjacent structures.Although surveying is a wonderful career with separate skills and licensing arrangements, civil engineers are educated in the fundamentals of surveying and mapping, as properly as geographic information systems. Surveyors also lay out the routes of railways, tramway tracks, highways, roads, pipelines and streets as nicely as function different infrastructure, such as harbors, earlier than construction.

Construction surveying:
Construction surveying is commonly performed through specialised technicians. Unlike land surveyors, the resulting design does now not have felony status. Construction surveyors operate the following tasks:

two Surveying existing stipulations of the future work site, consisting of topography, current constructions and infrastructure, and underground infrastructure when possible;
two two "lay-out" or "setting-out": putting reference factors and markers that will information the construction of new buildings such as roads or buildings;
two two  Verifying the location of constructions at some stage in construction;
two two  As-Built surveying: a survey performed at the end of the construction undertaking to verify that the work authorized was accomplished to the specifications set on plans.

Land Surveying:
In the United States, Canada, the United Kingdom and most Commonwealth nations land surveying is regarded to be a separate and wonderful profession. Land surveyors are not considered to be engineers, and have their very own professional associations and licensing requirements. The offerings of a licensed land surveyor are normally required for boundary surveys (to establish the boundaries of a parcel using its prison description) and subdivision plans (a plot or map based totally on a survey of a parcel of land, with boundary lines drawn internal the larger parcel to indicate the creation of new boundary traces and roads), each of which are commonly referred to as Cadastral surveying.

United States:
In the United States, civil engineers are normally employed via municipalities, development firms, consulting engineering firms, architect/engineer firms, the military, state governments, and the federal government. Each country requires engineers who offer their services to the public to be licensed by using the state. Licensure is got by way of assembly distinct education, examination, and work trip requirements. Specific requirements range through state. Typically licensed engineers must graduate from an ABET-accredited university or university engineering application with a minimum of bachelor's degree, pass the Fundamentals of Engineering exam, obtain numerous years of engineering trip beneath the supervision of a licensed engineer, then skip the Principles and Practice of Engineering Exam. After completing these steps and the granting of licensure by using a state board, engineers might also use the title "Professional Engineer" or PE in advertising and documents. Most states have applied mandatory persevering with training requirements to preserve a license.

United Kingdom:
A chartered civil engineer (known as licensed or professional engineer in other countries) is a member of the Institution of Civil Engineers, and has additionally passed membership exams. However a non-chartered civil engineer may be a member of the Institution of Civil Engineers or the Institution of Civil Engineering Surveyors. The description "Civil Engineer" is now not restricted to contributors of any unique professional organization even though "Chartered Civil Engineer" is.

Scandinavia:
In Scandinavian countries, civil engineer (civilingenjör (Swedish), sivilingeniør (Norwegian), civilingeniør (Danish)) is a first expert degree, approximately equal to Master of Science in Engineering, and a covered title granted to college students by using selected institutes of technology. As in English the phrase has its beginning in the big difference between civilian and military engineers, as in before the start of the 19th century solely navy engineers existed and the prefix "civil" was a way to separate those who had studied engineering in a ordinary University from their army counterparts. Today the diploma spans over all fields within engineering, like civil engineering, mechanical engineering, computer science, electronics engineering, etc.

There is commonly a slight difference between a Master of Science in Engineering degree and the Scandinavian civil engineer degree, the latter's programme having closer ties with the industry's demands. A civil engineer is the most established of the two; still, the area of expertise remains obfuscated for most of the public. A noteworthy distinction is the obligatory guides in mathematics and physics, regardless of the equivalent master's degree, e.g. pc science.

Spain:
In Spain, a civil engineering diploma can be acquired after four years of learn about in the a number branches of mathematics, physics, mechanics, etc. The earned diploma is referred to as Grado en Ingeniería Civil. Further research at a graduate school consist of master's and doctoral degrees.

Before the cutting-edge situation, that is, before the implementation of Bologna Process in 2010, a diploma in civil engineering in Spain should be obtained after three to six years of find out about and used to be divided into two most important degrees. In the first case, the earned diploma was once known as Ingeniero Técnico de Obras Públicas (ITOP), literally translated as "Public Works Engineer" bought after three years of find out about and equal to a Bachelor of Civil Engineering. In the 2nd case, the educational diploma was referred to as Ingeniero de Caminos, Canales y Puertos (often shortened to Ingeniero de Caminos or ICCP), that actually ability "Highways, Canals and Harbors Engineer", though civil engineers in Spain practice in the identical fields as civil engineers do elsewhere. This degree is equal to a Master of Civil Engineering and is acquired after 5 or six years of study depending on the school granting the title.

The first Spanish Civil Engineering School was the Escuela Especial de Ingenieros de Caminos y Canales (now called Escuela Técnica Superior de Ingenieros de Caminos, Canales y Puertos), mounted in 1802 in Madrid, accompanied by the Escuela Especial de Ayudantes de Obras Públicas (now known as Escuela Universitaria de Ingeniería Técnica de Obras Públicas de la Universidad Politécnica de Madrid), founded in 1854 in Madrid. Both faculties now belong to the Technical University of Madrid.

Transportation Engineering:
Transportation engineering is involved with moving humans and items efficiently, safely, and in a manner conducive to a shiny community. This entails specifying, designing, constructing, and preserving transportation infrastructure which includes streets, canals, highways, rail systems, airports, ports, and mass transit. It includes areas such as transportation design, transportation planning, site visitors engineering, some aspects of urban engineering, queueing theory, pavement engineering, Intelligent Transportation System (ITS), and infrastructure management.

Water Resources Engineering:
Water resources engineering is involved with the collection and management of water (as a herbal resource). As a discipline it therefore combines elements of hydrology, environmental science, meteorology, conservation, and resource management. This vicinity of civil engineering relates to the prediction and administration of both the first-rate and the volume of water in each underground (aquifers) and above ground (lakes, rivers, and streams) resources. Water resource engineers analyze and model very small to very massive areas of the earth to predict the quantity and content material of water as it flows into, through, or out of a facility. Although the proper design of the facility may also be left to other engineers.

Hydraulic engineering is concerned with the float and conveyance of fluids, basically water. This area of civil engineering is intimately related to the sketch of pipelines, water furnish network, drainage services (including bridges, dams, channels, culverts, levees, storm sewers), and canals. Hydraulic engineers plan these services the use of the concepts of fluid pressure, fluid statics, fluid dynamics, and hydraulics, among others.

Municipal Engineering:
Municipal engineering is involved with municipal infrastructure. This includes specifying, designing, constructing, and keeping streets, sidewalks, water grant networks, sewers, street lighting, municipal stable waste management and disposal, storage depots for a number bulk materials used for preservation and public works (salt, sand, etc.), public parks and cycling infrastructure. In the case of underground utility networks, it might also additionally include the civil component (conduits and access chambers) of the local distribution networks of electrical and telecommunications services. It can additionally include the optimizing of waste collection and bus provider networks. Some of these disciplines overlap with different civil engineering specialties, alternatively municipal engineering focuses on the coordination of these infrastructure networks and services, as they are frequently built simultaneously, and managed via the identical municipal authority. Municipal engineers can also additionally format the web site civil works for large buildings, industrial flora or campuses (i.e. get entry to roads, parking lots, potable water supply, remedy or pretreatment of waste water, web page drainage, etc.)

Civil engineering systems:
Civil engineering structures is a discipline that promotes the use of systems questioning to control complexity and trade in civil engineering inside its wider public context. It posits that the suitable development of civil engineering infrastructure requires a holistic, coherent understanding of the relationships between all of the essential factors that make a contribution to successful tasks while at the same time emphasising the importance of attention to technical detail. Its motive is to assist integrate the entire civil engineering mission life cycle from conception, through planning, designing, making, running to decommissioning.
