To prepare the bid, first a cost estimate is prepared to determine the costs and then establish the price(s). This involves reviewing the project's plans and specifications to produce a take-off or quantity survey, which is a listing of all the materials and items of work required for a construction project by the construction documents ...
In November 2010, CSI acquired Building Systems Design (BSD) to help advance software tools for specifications development and communication of building information across the building team. [2] [3] BSD is a software firm that is a leading developer of commercial master specifications and construction cost estimating software. BSD is involved ...
The most basic element of a cost estimate and therefore the cost database is the estimate line item or work item. [3] An example is "Concrete, 4000 psi (30 MPa)," which is the description of the item. In the cost database, an item is a row or record in a table (of items) and the description is a column or field for that record.
Shortly afterwards, the first finite element program (FEM) was applied in the German construction industry for plates, discs, and folding units. 1979 [2] In 1979, RIB launched its first program system, IDEALOG for AVA and cost estimation. It was used for all public construction administrations of the federal and state governments.
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 ...
B2W Software (formerly known as Bid2Win Software) [2] is based in Portsmouth, New Hampshire, and develops specialized software for heavy construction contractors to manage construction estimating and bidding, field tracking and analysis, equipment maintenance, resource scheduling and dispatching and eForms and reporting.
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. Both estimators and quantity surveyors must have a background education ...
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]
