Construction cost estimating software is computer software designed for contractors to estimate construction costs for a specific project. A cost estimator will typically use estimating software to estimate their bid price for a project, which will ultimately become part of a resulting construction contract. Some architects, engineers ...
A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate. A cost ...
Cost estimation models are mathematical algorithms or parametric equations used to estimate the costs of a product or project. The results of the models are typically necessary to obtain approval to proceed, and are factored into business plans, budgets, and other financial planning and tracking mechanisms.
A mudbrick catenary arch A catenary curve (left) and a catenary arch, also a catenary curve (right). One points up, and one points down, but the curves are the same. A catenary arch is a type of architectural arch that follows an inverted catenary curve. The catenary curve has been employed in buildings since ancient times.
Unlike a catenary arch, the parabolic arch employs the principle that when weight is uniformly applied above, the internal compression (see line of thrust) resulting from that weight will follow a parabolic curve. Of all arch types, the parabolic arch produces the most thrust at the base. Also, it can span the widest area.
A segmental arch is a type of arch with a circular arc of less than 180 degrees. [1] It is sometimes also called a scheme arch. [2] The segmental arch is one of the strongest arches because it is able to resist thrust. [3] [clarification needed] To prevent failure, a segmental arch must have a rise that is equal to at least one-eighth the width ...
Robert Maillart, c. 1925. Robert Maillart (16 February 1872 – 5 April 1940) was a Swiss civil engineer who revolutionized the use of structural reinforced concrete with such designs as the three-hinged arch and the deck-stiffened arch for bridges, and the beamless floor slab and mushroom ceiling for industrial buildings.
The arch, built with brownstone from Portland, Connecticut, was completed in 1886 at a cost of about $60,000, and dedicated on September 17, 1886. The north frieze, by Samuel James Kitson , tells a story of war with (on the right) a figure of General Ulysses S. Grant surveying his troops and (on the left) marines leaping from a boat to rush ...
