C. Do not confuse or and and; e.g., "It shall be free from defects of
workmanship and material which would impair its strength or durability." The use of
"or" for "and" or "and" for "or" in this sentence would result in a meaning not intended.
D. Do not use "and/or". The courts have considered this phrase to be
intentionally ambiguous and, therefore, to be interpreted in favor of the Contractor.
E. Use statements which are definite and do not contain words and phrases
which may be ambiguous. Examples:
"Remove the equipment from the building during the alterations and
reinstall the equipment after completion of the alterations." Do not say "Remove and
replace the equipment as indicated." "Replace" can mean "put back" or "reinstall".
"Remove the existing culverts and reinstall the culverts in the new
locations." Do not say "Replace the existing culverts as indicated on the drawings."
"Remove existing and provide electrical wiring." Do not say: "Replace the
electrical wiring" as this implies reinstallation of the old wiring.
F. "Provide" is defined in the Contract Clauses as "furnish and install". When
material or equipment is furnished by the Government directly or under other contracts
for installation by the contractor, the term, "install" should be used; however, the
contractor may be required to "provide" foundations, fastenings, etc., for the
installation. If the word "install" is used alone, the bidder or contractor has a right to
assume, on the basis of the definition cited, that the Government will "furnish" the
materials in question.
G. Certain terms and designations of work phases, rooms and areas
commonly used in Naval activities should not be used in construction specifications,
for example: Bulkhead (for wall), deck (for any floor), ladder (for stair), head (for
toilet), galley (for kitchen), overhead (for ceiling), etc.
H. Provide statements of direction, opposed to statements of information; e.g.,
"wall shall be painted" should read "paint the wall." "To be ...". "shall be ...", "will be ..."
does not affix responsibility.
USE OF ABBREVIATIONS AND SYMBOLS
In general, abbreviations should be avoided except those which are generally
understood and accepted and can be used economically: e.g., psig, cfm, kw. (The use
of ft., in., lbs., %, do not offer great savings).
