PREPARATION OF DRAWINGS
This chapter covers general requirements regarding A/E preparation of
construction contract drawings, including drawing format, arrangement,
drafting quality, nomenclature, signatures, scales, etc. The chapters on the
various design disciplines contain specific requirements relative to the
amount and type of technical content to be shown on the drawings for each
design submission required by the Appendix "A".
The preparation of drawings shall conform to the requirements of MIL-HDBK-
1006/1, "Policy and Procedures for Project Drawing and Specification
Preparation" and the requirements specified herein. Drawings must be
complete, accurate, and explicit. TYPICALLY, THE GOVERNMENT CANNOT LIMIT
BIDDING TO A SELECTED LIST OF CONTRACTORS KNOWN TO DO GOOD WORK. ANY
CONTRACTOR MAY BID THE PROJECT AND BIDDERS ARE NOT OBLIGATED TO VISIT THE SITE
PRIOR TO SUBMITTING BIDS. THEREFORE, DRAWINGS (AND SPECIFICATIONS) MUST LEAVE
LITTLE TO THE IMAGINATION. THEY MUST BE CLEAR, CONCISE, DETAILED, AND
THOROUGHLY COORDINATED. All elements of the work shall be properly
coordinated to ensure that there are no conflicts between disciplines or
between drawings and specifications. Provide sufficient detail to show the
extent, size, shape, and relationship between materials. Drawings and
specifications should preferably be separate. Avoid putting drawings in
specifications and specification data on drawings. DUPLICATION OF INFORMATION
ON THE DRAWINGS AND IN THE SPECIFICATIONS MUST BE AVOIDED.
General Drafting Quality
The A/E shall make every effort to avoid poor spacing, careless lettering,
weak lines and crowded drawings. Particular attention shall be given in the
preparation of drawings as to the amount of detail to be shown in a given
space. Avoid including unnecessary details or information which otherwise
does not improve the understanding of the work. Large scale details should be
provided as necessary to insure a clear presentation of the information.
Government Use of Original Drawings
The A/E shall forward the original mylar drawings to NORTHDIV at the Bidding
Document Submission. Original drawings are reproduced for advertisement for
construction bids by the government. In most cases the prints for bidders are
reduced half-size from the originals. In addition, the government uses a 35
MM filming system to permanently file record drawings. The quality of these
reduced prints and microfilm is a direct result of the drafting efforts of the
A/E preparing the drawings. The finest cameras and most carefully controlled
processing cannot produce good results unless the original drawing is of a
high quality. Accordingly, the following rules and requirements must be
SEPIAS OR SEPIA MYLARS ARE NOT ACCEPTABLE.
b) DIAZO-TYPE OR ELECTROSTATIC REPRODUCTION PROCESSES ARE NOT
DECALS AND "STICK-ONS" ARE NOT ACCEPTABLE.
SHADING SHALL NOT BE USED.
