  2. Basis of estimate - Wikipedia

    en.wikipedia.org/wiki/Basis_of_estimate

    A pivot table in BOEMax, a Basis of Estimate software package. To create a BOE companies, throughout the past few decades, have used spreadsheet programs and skilled cost analysts to enter thousands of lines of data and create complex algorithms to calculate the costs. These positions require a high level of skill to ensure accuracy and ...

  3. Estimation (project management) - Wikipedia

    en.wikipedia.org/wiki/Estimation_(project...

    In project management (e.g., for engineering), accurate estimates are the basis of sound project planning. Many processes have been developed to aid engineers in making accurate estimates, such as Analogy based estimation; Compartmentalization (i.e., breakdown of tasks) Cost estimate; Delphi method; Documenting estimation results; Educated ...

  4. Cost estimate - Wikipedia

    en.wikipedia.org/wiki/Cost_estimate

    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 ...

    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 ...

  6. 16 Divisions - Wikipedia

    en.wikipedia.org/wiki/16_Divisions

    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.

  7. Cost contingency - Wikipedia

    en.wikipedia.org/wiki/Cost_contingency

    The cost contingency which is included in a cost estimate, bid, or budget may be classified as to its general purpose, that is what it is intended to provide for. For a class 1 construction cost estimate, usually needed for a bid estimate, the contingency may be classified as an estimating and contracting contingency.

  8. Prestressed concrete - Wikipedia

    en.wikipedia.org/wiki/Prestressed_concrete

    Prestressed concrete is a highly versatile construction material as a result of it being an almost ideal combination of its two main constituents: high-strength steel, pre-stretched to allow its full strength to be easily realised; and modern concrete, pre-compressed to minimise cracking under tensile forces.

  9. Strain hardening exponent - Wikipedia

    en.wikipedia.org/wiki/Strain_hardening_exponent

    In one study, strain hardening exponent values extracted from tensile data from 58 steel pipes from natural gas pipelines were found to range from 0.08 to 0.25, [1] with the lower end of the range dominated by high-strength low alloy steels and the upper end of the range mostly normalized steels.
