LEARNING OBJECTIVE: Upon completing
this section, you should be able to explain the
estimating requirements for a construction
As project estimator, you will need to assemble
information about various conditions affecting the
construction of the project. This enables you to
prepare a detailed and accurate estimate. Drawings
should be detailed and complete. Specifications
should be exact and leave no doubt as to their intent.
Information should be available about local material,
such as quarries, gravel pits, spoil areas, types of soil,
haul roads and distances, foundation conditions, the
weather expected during construction, and the time
allotted for completion. You should know the number
and types of construction equipment available for use.
Consider all other items and conditions that might
affect the production or the progress of construction.
The construction drawings are your main basis for
defining the required activities for measuring the
quantities of material. Accurate estimating requires a
thorough examination of the drawings. You should
carefully read all notes and references and examine all
details and reference drawings. The orientation of
sectional views should be carefully checked.
Dimensions shown on drawings or computed figures
shown from those drawings should be used
preference to those obtained by scaling distances.
