Tube riding at Teahupo'o . Tube riding is a term used by surfers to describe riding well inside the curve or barrel of a finely-shaped breaking wave. Under the right conditions, waves in some areas, such as the Banzai Pipeline in Hawaii, form a moving "tube" or cylinder as they break. The most straightforward way to tube ride is by body surfing ...
Construction engineering, also known as construction operations, [1] is a professional subdiscipline of civil engineering that deals with the designing, planning, construction, and operations management of infrastructure such as roadways, tunnels, bridges, airports, railroads, facilities, buildings, dams, utilities and other projects.

Also Abrams' water-cement ratio law. A law which states that the strength of a concrete mix is inversely related to the mass ratio of water to cement. As the water content increases, the strength of the concrete decreases. abrasion The process of scuffing, scratching, wearing down, marring, or rubbing away a substance or substrate. It can be intentionally imposed in a controlled process using ...
By 1963, a new structural system of framed tubes had appeared in skyscraper design and construction. Fazlur Rahman Khan, a structural engineer from Bangladesh (then called East Pakistan) who worked at Skidmore, Owings & Merrill, defined the framed tube structure as "a three dimensional space structure composed of three, four, or possibly more frames, braced frames, or shear walls, joined at or ...
The CABE accredits university qualifications to use the title Chartered Building Engineer. [9] In the United Kingdom and Ireland, Chartered Building Engineers are involved within the design, planning, engineering, construction, legal compliance, fire safety, and maintenance of buildings. Their roles may vary from one practice to another.
Submerged floating tunnels can be anchored to the seafloor (left) or suspended from a pontoon (right) A submerged floating tunnel (SFT), also known as submerged floating tube bridge (SFTB), suspended tunnel, or Archimedes bridge, is a proposed design for a tunnel that floats in water, supported by its buoyancy (specifically, by employing the hydrostatic thrust, or Archimedes' principle).
One or more tube riders (often called "tubers") tether their tubes to a powered watercraft such as a motor boat or a personal watercraft. The riders are then towed through the water by the watercraft. In free floating tubing, the tube riders are untethered and often conveyed by the current of a waterway.
The following outline is provided as an overview of and topical guide to engineering: . Engineering is the scientific discipline and profession that applies scientific theories, mathematical methods, and empirical evidence to design, create, and analyze technological solutions cognizant of safety, human factors, physical laws, regulations, practicality, and cost.
