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

Effective Date: Jan. 6, 2011<br />
Revision: 2<br />
Approval: Kyle Ray<br />
5.4.1 IN GENERAL: The revision description area is located on the left side of<br />
the drawing title block (See Attachment "A"). It shall be used to record<br />
the type of revision that the drawing represents. A maximum of three<br />
revisions will be recorded on any given engineering drawing produced by<br />
<strong>Ventech</strong>. The person that is physically revising the drawing shall input<br />
their initials in the "By" block of the revision description area. They shall<br />
also input the type of revision along with the description. The "CHK"<br />
(checked by), "APP"(approved by) and "DATE" blocks shall be left blank<br />
for hand signatures and dates. Once the revision description area is filled<br />
with three revisions, the oldest revision shall be deleted and replaced with<br />
the new revision. If the preceding revision had hand signatures and/or<br />
dates in the "CHK" (checked by), "APP" (approved by) or "DATE" block,<br />
then these initials shall be electronically entered into their appropriate<br />
locations.<br />
5.4.2 The revision block is located on the lower right of the title block. (See<br />
Attachment "A"). It shall be used to record the current revision level of<br />
the drawing.<br />
5.4.3 PRELIMINARY ISSUES: Preliminary issues made during the<br />
development of a drawing shall bear the letter "A" in both the revision<br />
description area and the revision block. Subsequent revisions shall be<br />
dissimilated by using a numerical sequence, such as A1, A2, A3, etc.<br />
The revision description shall simply state the word "Preliminary".<br />
5.4.3.1 Preliminary drawings that are issued for reference do not need<br />
to be signed off in any of the checked by or the approval areas<br />
of the title block.<br />
5.4.4 CLIENT APPROVAL ISSUES: Drawings that are issued for client<br />
approval shall bear the letter "B" in both the revision description area and<br />
the revision block. Subsequent revisions shall be dissimilated by using a<br />
numerical sequence, such as B1, B2, B3, etc. The revision description<br />
shall simply state the words "Client Approval". At this time all preliminary<br />
revisions shall be deleted from the revision description area and only the<br />
client approval revisions shall be recorded henceforth.

5.4.4.1 Drawings that are being issued to the client shall have the<br />
"CHK" (checked by) and the "APP" (approved by) blocks in the<br />
revision description area hand signed. The "CHK" (checked by)<br />
block shall be hand signed by the person responsible for<br />
checking the drawing. The "APP" (approved by) block shall be<br />
hand signed by the department manager and the Project<br />
Manager. The "DATE" block next to the approval block shall<br />
have the date hand signed by the Project Manager.<br />
5.4.5 APPROVED FOR CONSTRUCTION ISSUES: Drawings that are issued<br />
approved for construction shall bear the number "0" (zero) in both the<br />
revision description area and the revision block. The revision description<br />
shall simply state the words "Approved For Construction". Subsequent<br />
revisions shall be dissimilated by using a numerical sequence, such as 1,<br />
2, 3, etc. The revision description shall briefly describe what was revised<br />
on the drawing.<br />
5.4.5.1 Drawings that are being issued for construction shall follow the<br />
same steps as defined in this Procedure, section 5.4.4.1. In<br />
addition to those steps, the checked and approval blocks next<br />
to the confidential statement are to be hand signed and dated<br />
(See Attachment "A"). These blocks are to be signed only if<br />
the drawing is at revision "0". Revision "0" indicates that the<br />
drawing is "Approved for Construction". The following<br />
personnel shall be responsible for signing and dating these<br />
blocks.<br />
"Drawn" block - Entered electronically by the<br />
person when the drawing was<br />
generated. (See section 5.1.3 of<br />
