The term "cutoff" refers to the fact that the new line cuts off distance (and/or time) and is, therefore, shorter distance-wise (or time-wise) than the old line. This is often the case, although the primary reason for building the cutoff may be to create a line with a better gradient profile, or other desirable features usually related to efficiency of operation that are lacking in the old ...
Cut off. Also see Reverser handle. A variable device on steam locomotives that closes the steam valve to the steam cylinder before the end of the piston stroke, thus conserving steam while letting steam in the cylinder expand under its own energy. Cutting A channel dug through a hillside to enable rail track to maintain a shallow gradient.
Queen strut: 1)(U.K.) A queen post which does not carry a plate.; [23] 2)(U.S.) A queen post not part of a truss in the engineering sense and in compression (a more modern definition than 2)in Queen Post above). [24] Lateral Queen – a pair of braced posts between a tie beam and collar beam. Prince – A strut associated with a king post truss.
A dutchman, or in some uses graving piece, is a matching piece of good material used to replace a relatively small damaged area that has been cut out of a larger item, to avoid having to replace the entire item; or, any of various techniques for accomplishing such a repair. In some cases, the meaning has been extended to include small pieces ...
In civil engineering, a cut or cutting is where soil or rock from a relative rise is removed. Cuts are typically used in road, rail, and canal construction to reduce a route's length and grade. Cut and fill construction uses the spoils from cuts to fill in defiles to create straight routes at steady grades cost-effectively.
A different alternative to the concept of frontage roads in urban freeways is the local–express system, which is designed to handle closely spaced interchange ramps without disrupting through traffic. Unlike frontage roads, the local lanes are typically high-speed fully controlled-access lanes, conforming to freeway requirements.
The EPC contractor coordinates all design, procurement and construction work and ensures that the whole project is completed as required and in time. They may or may not undertake actual site work. EPC companies are often used in large-scale projects, such as power plants, refineries, chemical processing facilities, infrastructure projects, and ...
If time is not crucial, owners may take a prudent approach to finish design and get a fixed lump-sum price before starting construction (the design–bid–build process). However, if there is a reason to speed project delivery, Fast-track can be used with any project delivery strategy, such as CM at Risk and Agency CM (see Construction ...
