5.1.3 The person generating the drawing is responsible for inputting their name
or initials along with the current date in the "BY" (drawn by) area in the
title block. It is the responsibility of the department manager to ensure
that the "start date" is recorded on the document and in the "Drawing
Status Report".
5.1.4 The drawing status report shall be issued to each department manager
periodically as required by changes in drawing status. This will ensure
that the reports are readily available to any employee needing to certify
the status of a drawing.
5.1.5 All magnetic copies of drawings shall be stored and archived in
accordance with Procedure 4.5-7 "Magnetic Data Control".
5.1.6 It is the responsibility of each department manager to maintain files
containing hard copies of drawings. The original drawings shall be stored
in a safe place to be readily retrieved for future copies. If necessary, a
copy of the original can be placed in a stick file or other suitable location
for reference to other disciplines. All drawings that have "hand" signatures
in the proper blocks, as defined in this procedure, shall be the original.
When an approved drawing is revised, the previously approved drawing
shall have the word "VOID" stamped or written in ink on the original. The
word "void" on these drawings shall ensure that only the current revision
is in circulation. Approved drawings that have been voided, shall be kept
for historical or possible legal reference. Each department shall have work
instructions outlining how drawings are to be maintained within their
department.
5.1.7 The drawing status report will be issued periodically in accordance with
the document matrix.
5.2 ENGINEERING DRAWING NUMBERING ASSIGNMENT
5.2.1 When a drawing is generated for a project, study or proposal a drawing
number shall be assigned. Duplicate drawing numbers shall be
dissimilated by the job number. If the drawing is a computer generated
drawing, then the drawing number and the electronic file name are the
same.

5.4.1 IN GENERAL: The revision description area is located on the left side of
the drawing title block (See Attachment "A"). It shall be used to record
the type of revision that the drawing represents. A maximum of three
revisions will be recorded on any given engineering drawing produced by
Ventech. The person that is physically revising the drawing shall input
their initials in the "By" block of the revision description area. They shall
also input the type of revision along with the description. The "CHK"
(checked by), "APP"(approved by) and "DATE" blocks shall be left blank
for hand signatures and dates. Once the revision description area is filled
with three revisions, the oldest revision shall be deleted and replaced with
the new revision. If the preceding revision had hand signatures and/or
dates in the "CHK" (checked by), "APP" (approved by) or "DATE" block,
then these initials shall be electronically entered into their appropriate
locations.
5.4.2 The revision block is located on the lower right of the title block. (See
Attachment "A"). It shall be used to record the current revision level of
the drawing.
5.4.3 PRELIMINARY ISSUES: Preliminary issues made during the
development of a drawing shall bear the letter "A" in both the revision
description area and the revision block. Subsequent revisions shall be
dissimilated by using a numerical sequence, such as A1, A2, A3, etc.
The revision description shall simply state the word "Preliminary".
5.4.3.1 Preliminary drawings that are issued for reference do not need
to be signed off in any of the checked by or the approval areas
of the title block.
5.4.4 CLIENT APPROVAL ISSUES: Drawings that are issued for client
approval shall bear the letter "B" in both the revision description area and
the revision block. Subsequent revisions shall be dissimilated by using a
numerical sequence, such as B1, B2, B3, etc. The revision description
shall simply state the words "Client Approval". At this time all preliminary
revisions shall be deleted from the revision description area and only the
client approval revisions shall be recorded henceforth.
