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 that are definite and do not contain words/phrases that may be
"Remove the equipment from the building during the alterations and reinstall the
equipm ent after completion of the alterations." Do NOT use "Remove and
replace the equipment as indicated." "Replace" can mean "put back" or
"Remove the existing culverts and reinstall the culverts in the new locations." Do
NOT use "Replace the existing culverts as indicated on the drawings."
"Remove existing and provide electrical wiring." Do NOT use : "Replace the
electrical wiring" as this implies reinstallation of the old wiring.
f. "Provide" is defined in the Contract Clauses as "fu rnish and install". When
material or equipment are 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 designation s of work phases, rooms and areas commonly used in
Naval activities should NOT be used in construction specifications. Examples: Bulkhead
(for wall), deck (for floor), ladder (for stair), head (for toilet), galley (for kitchen),
overhead (for ceiling), et c.
h. Provide statements of direction as opposed to statements of information.
Examples: "wall shall be painted" should read "paint the wall." "To be ...", "shall be ...",
"will be ..." does not affix responsibility.
6.9 USE OF ABBREVIATIONS AND SYMBOLS
In general, abbreviations should be avoided except those that 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).
The use of symbols is undesirable fo r three basic reasons: (1) most are difficult to
produce on a typewriter; (2) they frequently have more than one meaning; (3) the typist
may not know what is intended and therefore type an improper symbol. Feet ('), inch ("),
degree (o), pound and number (#), should be written out, except that number may be
abbreviated (No.). In the text it is preferable to spell figures except where they give
dimensions, for example: "Ten buildings", "100 feet long"; however, "one" and "zero",
