Dimensions in the construction industry
Some of these units, such as area, can be obtained by the multiplication of two other dimensions, so for example (a x b) gives the area ab. Other measurements such as volume can be established by combining three linear measurements. The volume of say, a cylinder may be given by multiplying the area by the height (a x b x h).
Dimensions are critical for co-ordinating building components and ensuring each fits correctly in its allocated place in a construction. Dimensionally co-ordinated products allow designers to select items which they can be confident will fit together (co-ordinate) dimensionally with the structure and other components to accepted tolerances.
The Geospatial Glossary, published by the Geospatial Commission, and accessed on 17 September 2022, defines the dimension of a mathematical space (or object) as: ‘…the minimum number of coordinates needed to specify any point within it.’ eg 1D, 2D, 3D etc.
