[This template must be edited for each project.  In doing so, specifier
must add job-specific requirements.  Brackets are used in the text to
indicate designer choices or locations where text must be supplied by
the designer.  Once the choice is made or text supplied, remove the
brackets.  The specifications must also be edited to delete
specification requirements for processes, items, or designs that are not
included in the project \-- and specifier's notes such as these.  To
seek a variance from requirements in the specifications that are
applicable, contact the Engineering Standards Manual
