  2. Construction estimating software - Wikipedia

    en.wikipedia.org/wiki/Construction_estimating...

    [5] As cost estimating programs became more and more popular over the years, more advanced features, such as saving data for reuse, mass project-wide changes, and trade-specific calculations, have become available. [6] For example, programs that are designed for building construction, include libraries and program features for traditional builders.

  3. Value of work done - Wikipedia

    en.wikipedia.org/wiki/Value_of_work_done

    The value of work done (VOWD) is a project management technique for measuring and estimating the project cost at a point in time. It is mainly used in project environments of the Petroleum industry and is defined as the value of goods and services progressed, regardless of whether or not they have been paid for or received. The primary purpose ...

    A Allocation of costs is the transfer of costs from one cost item to one or more other cost items. Allowance - a value in an estimate to cover the cost of known but not yet fully defined work. As-sold estimate - the estimate which matches the agreed items and price for the project scope. B Basis of estimate (BOE) - a document which describes the scope basis, pricing basis, methods ...

  5. Construction surveying - Wikipedia

    en.wikipedia.org/wiki/Construction_surveying

    In other types of construction projects, arbitrary "plan north" reference lines may be established, using Cartesian coordinates that may or may not necessarily correspond to true coordinates. The technique is called localized grid. This method uses the plan building grids as their own ordinates.

    The 16 Divisions of construction, as defined by the Construction Specifications Institute (CSI)'s MasterFormat, is the most widely used standard for organizing specifications and other written information for commercial and institutional building projects in the U.S. and Canada. In 2004, MasterFormat was updated and expanded to 50 Divisions. [1]

  7. Building estimator - Wikipedia

    en.wikipedia.org/wiki/Building_estimator

    A building estimator or cost estimator is an individual that quantifies the materials, labor, and equipment needed to complete a construction project. Building cost estimating can concern diverse forms of construction from residential properties to hi-rise and civil works.

  8. Material efficiency - Wikipedia

    en.wikipedia.org/wiki/Material_efficiency

    Building construction often is resource-intensive. Material efficiency is a description or metric (( M p) (the ratio of material used to the supplied material)) which refers to decreasing the amount of a particular material needed to produce a specific product. [ 1 ]

    The width of the ribs is typically 130 mm (5 in) to 150 mm (6 in), and ribs usually have steel rod reinforcements. [5] The distance between ribs is typically 915 mm (3 ft). [3] The height of the ribs and beams should be 1 ⁄ 25 of the span between columns. [3] The width of the solid area around the column should be 1 ⁄ 8 of
