Introduction to Reading Plans and Elevations
This module introduces techniques for reading construction drawings and specifications.

Construction drawings tell carpenters and other skilled tradespeople how to build a specific building or structure.
A specification is a contractual document used along with the construction drawings. It contains detailed written instructions that supplement the set of drawings.

As a carpenter, it is extremely important that you interpret construction drawings and specifications correctly. Failure to do so may result in:

• Costly rework and unhappy customers

• Legal liability (depending on the severity of the mistake)
