written  data,  another  drawing,  or  any  combination  of these. Any error or omission of information in these sources  will  result  in  inaccuracies  in  the  drawing; therefore, the first check is to make sure that the source accurately provides everything needed to make the drawing.  “Editing”  means  that  you  are  inspecting  the drawing   to   make   sure   that   the   procedures   and conventions   prescribed   in   relevant   NAVFAC publications and military standards are followed. It might be said that editing begins as soon as drawings begin-meaning that you must constantly edit drawings to  ensure  that  proper  procedures  and  conventions  are followed at the time the drawings are made. When checking and editing a detail drawing, the checker  ALWAYS  uses  a  print  of  the  drawing,  rather than the original. That way, any corrections that need to be made can be marked with a colored pencil or pen on the print without disturbing or destroying the original. The detail drafter then uses the marked-up print to make corrections to the original drawing. After all of the corrections have been made, the checker compares a print  of  the  corrected  drawing  with  the  originally marked-up  print. For a thorough job of checking and editing, you should  first  make  an  overall  check  with  the  following questions  in  mind: 1. Does the drawing reproduce well? Any poorly defined  or  weak  line  work  and  lettering  must  be corrected. 2. Does the size and format of the drawing conform to  the  MIL-HDBK-1006/1  requirements  for  Naval Facilities   Engineering   Command   (NAVFACENG- COM)  drawings?  As  specified  in  that  publication,  the project  drawings  should  be  prepared  on  flat  C-,  D-,  or F-size paper. It also specifies that a vertical title block format  is  mandatory  for  D-size  drawings  and  optional for F-size. Examples of both horizontal and vertical format title blocks can be found in MIL-HDBK-1006/1. 3. For a set of drawings, is a different drawing number assigned to each sheet and are all of the drawing numbers correct? Is the set of drawings arranged in the correct  order  as  specified  in  MIL-HDBK-1006/1.  That is, are they arranged as follows: a. Title sheet and index of drawings (only for projects containing 60 or more drawings). b. Plot and vicinity plans (including civil and utility plans). This sheet should include an index for small  projects. c.  Landscape  and  irrigation. d. Architectural. e.  Structural. f.  Mechanical  (heating,  ventilating,  and  air conditioning). g.  Plumbing. h. Electrical. i. Fire protection. If the overall check is satisfactory, proceed with more detailed questions, such as the following: 1. Is the method of projection appropriate? 2. Are the views shown the minimum number required to show all the data? 3. Are  sectional  views  constructed  correctly  and is the section lining correct? 4. Are line conventions and symbols consistent with  the  requirements  of  appropriate  and  current standards? Are all symbols (especially nonstandard ones) explained in a legend? 5. Are proper scales used for the drawing and are the  scales  shown?  Appropriate  scales  for  construction drawings are as follows: a. Floor plans and elevations: 1/4", 3/16", 1/8", or 1/16" = 1´ – O". b.   Architectural   details:   3/4",   1   1/2",   or 3" = 1´ – 0´. c. Molding sections and similar details: full scale or half scale. d. Mechanical and electrical details: 3/8", 1/2", 3/4", or 1" = 1´ – 0´. e.  Structural  details:  3/8",  1/2",  3/4",  or 1" = 1´ – 0´. f.   Structural   erection   drawings   (such   as structural  floor  and  roof  framing  plans):  1/8"  or 1/16"  =  1´  -  0". g. Site (plot) plans: 1" = 10´, 20´, 30´, 40´, 50´, 60´, 100´, or 200´. h. Utility plans: 1" = 20´, 30´, 40´, or 50´. 6.  Are  graphic  scales  shown  as  required  by NAVFACENGCOM  (MIL-HDBK-1006/1)? 7.  Do  the  dimensions  agree  with  those  shown  in the data source? Does the sum of partial dimensions equal the overall dimensions? 4-11
