  2. Quantity take-off - Wikipedia

    en.wikipedia.org/wiki/Quantity_take-off

    With BIM quantity take-off can be conducted almost automatically given that the type of materials, their quantity and price is included in the model. [2] It is known that construction projects often run overtime and over budget and one of the reasons is lack of accuracy in quantity takeoff and estimates. [3] [2]

  3. Construction waste - Wikipedia

    en.wikipedia.org/wiki/Construction_waste

    Much building waste is made up of materials such as bricks, concrete and wood damaged or unused during construction. Observational research has shown that this can be as high as 10 to 15% of the materials that go into a building, a much higher percentage than the 2.5-5% usually assumed by quantity surveyors and the construction industry. Since ...

  4. Cost estimate - Wikipedia

    en.wikipedia.org/wiki/Cost_estimate

    Additional documentation may accompany the estimate, including quantity takeoff documentation and supporting calculations, quotes, etc. Although the pursuit of cost estimate accuracy should always be encouraged, a study in 2002 found that the estimates used to determine whether important infrastructure should be built were "highly and ...

  9. Building services engineering - Wikipedia

    en.wikipedia.org/wiki/Building_services_engineering

    Many tasks in building services engineering involve the use of engineering software, for example to design/model or draw solutions. The most common types of tool are whole building energy simulation [3] and CAD (traditionally 2D) or the increasingly popular Building Information Modeling (BIM) which is 3D. 3D BIM software can have integrated tools for Building Services calculations such sizing ...
