Dimensioning, like any skill, is taughtnot (unfortunately) in schools but in practice, with seasoned veterans showing interns the few tips needed to master the skill. Usually columns are laid out in a grid and one axis is lettered and the other is numbered thus column B5 is at the intersection of lines 'B' and '5'. It is our goal to provide clear answers to issues of concern to the Institutes membership and share case studies and best practices. The review will include the consistency of gridlines and their associated dimensions and building components across the documents, any discrepancies found will be flagged. The purpose of dimensioning, like every other aspect of the construction drawings, is to give the contractor just enough information to build the project, and . Every dimension should serve a purpose, and no other dimension should be serving the same purpose. They will also vary in thickness or line weight. Lines can be drawn to indicate hidden objects, cutting lines, boundaries and so on. In the case of Architectural drawings, the dimensions and appearance of the column are important to the architecture of the building so information such as the following is illustrated: Dimensions: Length, width or diameter. The structural engineer will design the support framing for the building in addition to miscellaneous equipment supports and concrete pads. Which one is easier to read?
