Rigid Pavement
Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods."Highway engineering." McGraw-Hill Concise Encyclopedia of Science and Technology. New York: McGraw-Hill, 2006. Credo Reference. Web. 13 February 2013. Highway engineering became prominent towards the latter half of the 20th century after World War II. Standards of highway engineering are continuously being improved. Highway engineers must take into account future traffic flows, design of highway intersections/interchanges, geometric alignment and design, highway pavement materials and design, structural design of pavement thickness, and pavement maintenance.

Blue Ridge Parkway
The Blue Ridge Parkway is a National Parkway and National Scenic Byway, All-American Road in the United States, noted for its scenic beauty. The parkway, which is the longest linear park in the U.S., runs for through 29 counties in Virginia and North Carolina, linking Shenandoah National Park to Great Smoky Mountains National Park. It runs mostly along the spine of the Blue Ridge Mountains, Blue Ridge, a major mountain chain that is part of the Appalachian Mountains. Its southern terminus is at U.S. Route 441 in North Carolina, U.S. Route 441 (US 441) on the boundary between Great Smoky Mountains National Park and the Qualla Boundary of the Eastern Band of Cherokee Indians in North Carolina, from which it travels north to Shenandoah National Park in Virginia. The roadway continues through Shenandoah as Skyline Drive, a similar scenic road which is managed by a different National Park Service unit. Both Skyline Drive and the Virginia portion of the Blue Ridge Parkway are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tunnel
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two portals common at each end, though there may be access and ventilation openings at various points along the length. A pipeline differs significantly from a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment.Salazar, Waneta.

Bridge
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge, dating from the 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of ...

Academic Institution
An academic institution is an educational institution dedicated to education and research, which grants academic degrees. See also academy and university. Types * Primary schools – (from French ''école primaire'') institutions where children receive the first stage of compulsory education known as primary or elementary education. ''Primary school'' is the preferred term in the United Kingdom and many Commonwealth Nations, and in most publications of the United Nations Educational, Scientific, and Cultural Organization (UNESCO). In some countries, and especially in North America, the term '' elementary school'' is preferred. Children generally attend primary school from around the age of four or five until the age of eleven or twelve. * Secondary schools – institutions where the final stage of compulsory schooling, known as secondary education, takes place. It follows on from primary or elementary education. There are many different types of secondary school and the termi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Construction
A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are paved. The words "road" and "street" are commonly considered to be interchangeable, but the distinction is important in urban design. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically, many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized b ...

General Contractor
A contractor (North American English) or builder (British English), is responsible for the day-to-day oversight of a construction site, management of vendors and trades, and the communication of information to all involved parties throughout the course of a building project. In the United States, a contractor may be a sole proprietor managing a project and performing labor or carpentry work, have a small staff, or may be a very large company managing billion dollar projects. Some builders build new homes, some are remodelers, some are developers. Description A general contractor is a construction manager employed by a client, usually upon the advice of the project's architect or engineer. General Contractors are mainly responsible for the overall coordination of a project and may also act as building designer and construction foreman (a tradesman in charge of a crew).

Public Works
Public works are a broad category of infrastructure projects, financed and procured by a government body for recreational, employment, and health and safety uses in the greater community. They include public buildings ( municipal buildings, schools, and hospitals), transport infrastructure ( roads, railroads, bridges, pipelines, canals, ports, and airports), public spaces (public squares, parks, and beaches), public services ( water supply and treatment, sewage treatment, electrical grid, and dams), environmental protection ( drinking water protection, soil erosion reduction, wildlife habitat preservation, preservation and restoration of forests and wetlands) and other, usually long-term, physical assets and facilities. Though often interchangeable with public infrastructure and public capital, public works does not necessarily carry an economic component, thereby being a broader term. Construction may be undertaken either by directly employed labour or by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consulting Firm
A consulting firm or simply consultancy is a professional service firm that provides expertise and specialised labour for a fee, through the use of consultants. Consulting firms may have one employee or thousands; they may consult in a broad range of domains, for example, management, engineering, and so on. Management consultants, in particular, typically work with company executives and provide them with generalists and industry-specific specialists, known as subject-matter experts, usually trained in management or in business schools. The deliverable of a management consultant is usually recommendations for achieving a company objective, leading to a company project. Many consulting firms complement the recommendations with implementation support, either by the consultants or by technicians and other experts. Consulting services are part of the professional services and account for several hundred billion dollars in annual revenues. Between 2010 and 2015, the 10 largest cons ...

Regulation And Licensure In Engineering
Regulation and licensure in engineering is established by various jurisdictions of the world to encourage life, public welfare, safety, well-being, then environment and other interests of the general public and to define the licensure process through which an engineer becomes licensed to practice engineering and to provide professional services and products to the public. As with many other professions and activities, engineering is often a restricted activity. Relatedly, jurisdictions that license according to particular engineering discipline define the boundaries of each discipline carefully so that practitioners understand what they are competent to do. A licensed engineer takes legal responsibility for engineering work, product or projects (typically via a seal or stamp on the relevant design documentation) as far as the local engineering legislation is concerned. Regulations require that only a licensed engineer can sign, seal or stamp technical documentation such as report ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
