LANTNAVFACENGCOM A&E GUIDE
H. Minimize the use of cross references and in no case use paragraph
numbers for this purpose. If necessary to refer to a particular paragraph, do so by its
title and the section number and title under which it is to be found. Cross references of
the following type are totally unnecessary: "Painting of the wood work is covered
under "`Painting"' or "painting is specified hereinafter".
I. Do not place upon the contractor the responsibility for the possible
inaccuracy of, or the lack of, information on the part of the Government; e.g., never use
sentences similar to "although the drawings indicate approximately the conditions that
are likely to be found, bidders should satisfy themselves as to the actual conditions, for
while they are believed to be shown, the Government does not guarantee the accuracy
of the information given and the bidder shall assume all responsibility in the use of
such". Remember that the Government is responsible for the accuracy and
sufficiency of the information it gives to bidders or contractors and the A&E is in
turn responsible to the Government for that same information. It will be necessary to
establish in the project specification a definite basis of bid. For example, on a roof
rehabilitation project where the extent of defective construction is unknown, the
specification shall set forth, as a basis of bid, a definite amount of work to be performed
and provide for adjustment in accordance with the Contract Clauses if the extent of
work varies from the amount stated under the basis of bid.
J. Do not include "warranties" in technical sections unless they are for more
than one year, and generally not unless they are included in the NAVFAC guide
specification. A one year warranty is covered in the Contract Clauses.
K. Do not set up a paragraph in the various sections entitled "Work not
Included". Specify the work that is included under the respective sections.
L. Specifications should clearly delineate equipment, ducts and piping
systems which are required to be insulated. The phrase "insulating all ducts except in
conditioned spaces" has resulted in differences of opinion and claim situations; also all
duct systems should be appropriately designated as supply, exhaust, fresh air intake, or
return to further clarify insulating requirements.
MISUSE OF WORDS
A. Do not confuse any and all; e.g., "Correct any defects" should read "Correct
B. Do not confuse either or both; e.g., "Paint sheet metal on either side"
should read "Paint sheet metal on both sides." "Either" implies a choice.
