It is assumed the Contractor is familiar with standard first class installation procedures.
Therefore, these Specifications do not attempt to include every detail or operation
necessary for the complete installation.
It should be particularly noted that the terms "furnish" and "provide" are interchangeable
and that each of these means to provide, install and connect, unless otherwise stated.
