  2. Construction estimating software - Wikipedia

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

    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, construction managers, and others may also use cost estimating software to prepare cost estimates for purposes other than bidding such as budgeting ...

  3. Subbase (pavement) - Wikipedia

    en.wikipedia.org/wiki/Subbase_(pavement)

    Layers in the construction of a mortarless pavement: A.) Subgrade B.) Subbase C.) Base course D.) Paver base E.) Pavers F.) Fine-grained sand. In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement ...

  4. Grading (earthworks) - Wikipedia

    en.wikipedia.org/wiki/Grading_(earthworks)

    Section through railway track and foundation showing the sub-grade. Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, [1] for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage.

  5. Subgrade - Wikipedia

    en.wikipedia.org/wiki/Subgrade

    In transport engineering, subgrade is the native material underneath a constructed road, [1] pavement or railway track (US: railroad track). It is also called formation level . The subgrade provides support to the subbase level and acts as an integral load-bearing layer.

  7. Pavement engineering - Wikipedia

    en.wikipedia.org/wiki/Pavement_engineering

    Pavement engineering is a branch of civil engineering that uses engineering techniques to design and maintain flexible and rigid pavements.This includes streets and highways and involves knowledge of soils, hydraulics, and material properties.

  8. Glossary of construction cost estimating - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_construction...

    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 ...

  9. Falling weight deflectometer - Wikipedia

    en.wikipedia.org/wiki/Falling_weight_deflectometer

    FWD data is most often used to calculate stiffness-related parameters of a pavement structure. The process of calculating the elastic moduli of individual layers in a multi-layer system (e.g. asphalt concrete on top of a base course on top of the subgrade) based on surface deflections is known as "backcalculation", as there is no closed-form solution.
