ESTIMATING LUMBER IN CONSTRUCTION

Although the use of lumber is quite limited nowadays to ornamental parts of the structure, it would still be best to learn the use of it in the major members like they were before. Some countries still prefer lumber over the other materials especially for residences.

Unlike the volume measured in cubic meters for concrete and length, also in meters for steel reinforcement, lumber uses board feet in measurement. A board feet is defined as the volume of lumber given its width (in inches) by length (in inches) and thickness (in inches). But with measurement of length in inches being cumbersome, the formula introduces a divisor of 12 to account for the length of the lumber in feet.
