DRAWING MANAGEMENT SYSTEM

CSBP uses the electronic document management system (Domino.Doc) to manage all controlled

drawings and to maintain information relating to controlled drawings. This system has two basic

functions.

a. Drawing information database

This database stores all information on all CSBP engineering drawings including:

•

drawing numbers

• drawing titles

• drawing revision number

• security access levels to drawing information and to drawing files

• revision history

• drawing activity log

Individual records are entered into the Domino.doc database for all CSBP drawings produced.

b. Drawing file management

Domino.doc provides links to all drawing files including past revisions. From the links, and with

appropriate access authority, drawing files can be opened for viewing or checked out for editing.

Refer to User Guide to Domino.doc UG-04-041-03 for detailed instructions in the use of

Domino.doc.

6.

REQUEST FOR DRAFTING SERVICES

To initiate in-house design or drafting work, the Responsible Officer shall provide the Design

Office Supervisor with full work scope details, cost centre (if required) and requested completion

date, together with any preliminary draft sketches or other relevant data.



Drawing Management

ES-14-101-02



For any large or complex design or drafting jobs that have fixed completion dates, an assessment

shall be carried out to determine the impact on other work commitments and resource levels before

authorisation to carry out the work is given.

7.

DOCUMENT CONTROL CHART

7.1 IN-HOUSE DRAWINGS

All in-house design or drafting work shall, at the discretion of the Design Office Supervisor or if

required by the Responsible Officer, be managed at an individual drawing and or activity level

using a Project Document Control Chart.

7.2 EXTERNAL DRAWINGS

Consultants and Contractors, in consultation with the Responsible Officer, shall prepare a Project

Document Control Chart as the basis for the management of the particular job and the recording of

its progress.

The need for detailed information may vary from job to job, depending on the complexity of the

Works and contractual arrangements. The Responsible Officer shall specify the level of

information required in contract documentation.

Consultants and Contractors can use their own Project Document Control Chart subject to the

approval of the Responsible Officer.

8.

ALLOCATION OF DRAWING NUMBERS

A drawing number shall be allocated prior to commencement of drafting activity on any new

drawing.

Drawing numbers shall be allocated in accordance with the numbering conventions and rules

detailed in CSBP Engineering Standard Drawing Numbering (ES-14-101-04).

Allocation, logging and administration of drawing numbers are the responsibility of the Drawing

Office. From information supplied, the Drawing Office shall assign a number, enter relevant details

into the Drawing Management System and advise the request originator the drawing number.

Note:

For externally produced drawings, CSBP Drawing Office, in conjunction with the

Responsible Officer, shall allocate individual drawing numbers based on the

Consultant/Contractor’s Project Document Control Chart or reserve blocks of numbers

for allocation by the external Drawing Control function responsible for managing the

project drawings during the development phase. All reserved numbers or blocks of

numbers shall be recorded in the Drawing Management System.



Drawing Management

ES-14-101-02



9.

DRAWING REVISIONS

9.1

GENERAL

Numeric or alpha character(s) shall be used in the Drawing Title and Revisions blocks to indicate

the revision level.

Any update/editing done to a drawing will result in the drawing being changed to the next revision.

A brief but informative statement of the revision made, and where applicable the appropriate

change order, project or other reference code shall be shown in the revision block.

Refer to Appendix 1 and 2 for approval sign-off requirements.

9.2

PRELIMINARY DESIGN LEVEL (ALPHA REVS)

During the development phase, prior to "approved for construction" status, alpha capital letters,

incrementing upwards from ‘A’ shall be used to reflect changes made to the drawing since the last

revision.

Note: Letters “I”, “O” and “Q” shall not be used. Revisions after “Z” shall be “AA”, “AB”, etc.

The Responsible Officer or Draftsperson shall maintain control and ownership of these revision

levels during the drawing development stage.

9.3

APPROVED DESIGN LEVEL (NUMERIC REVISIONS)

Numeric revision numbers shall be used for all drawings after they have been elevated to

“Approved” status. Revision numbers shall commence at Rev 0 and increment upwards by one for

each approved revision thereafter. Normally, Revision 0 is synonymous with “Approved for

Construction” status, however, it can also be used to indicate other “Approved” statuses, for

example: “As-Built” status - when it is necessary to create a new drawing to reflect as-built

conditions.

After approval sign-off on the paper copy of the drawing or electronic approval of the drawing, the

Draftsperson shall upload and or store the drawing into the suitable drawing repository.

9.4

AS-BUILT DRAWINGS

Drawings shall be revved up to “As-Built” status whenever there are any changes on any drawings

that have occurred during construction or commissioning that are not accurately shown on the

drawings already issued.

If there are no changes during construction or commissioning and the latest drawing revision

reflects the “As-Built” condition, it is not necessary to update the drawing to state “As-Built” in the

revision block.



Drawing Management

ES-14-101-02



9.5 CANCELLED DRAWING NUMBERS

9.5.1 Non-Reusable Drawing Numbers

If drawings have been received and registered by CSBP Drawing office and are subsequently

cancelled, the CSBP drawing number shall NOT be used again.

For traceability, the drawing to be cancelled shall be revved-up, a brief statement made in the

revision block and diagonally across the drawing in large text the wording:

• “DRAWING CANCELLED”. This applies to drawings where the information is no longer

valid and another drawing has not replaced it.

• “DRAWING CANCELLED – SUPERSEDED BY DRAWING NUMBER ………………..…”

This applies to drawings where the information is no longer valid and another drawing hasreplaced it.

Note: This requirement does not apply to normal drawing revisions i.e. DO NOT cancel a

historical revision because the next revision of the same drawing has superseded it.

Note: The Drawing Management System “Comments Field” shall record details of the

cancellation to maintain traceability of drawing information.

9.5.2 Reusable Drawing Numbers

If a new drawing number has been allocated either singly or as part of a block of numbers and this

number or block of numbers is not required, the issue record in the Drawing Management Systemshall be deleted when authorised by the Responsible Officer. The drawing number or block of

numbers may then be allocated to other drawings.

10.

PROJECT DEVELOPMENT DRAWINGS

10.1

GENERAL

“Project Development” versions of existing drawings enable proposals to modify plant, equipment

or other facilities to proceed without impacting the accuracy of information on the existing

drawings.

10.2

NUMBERING PROJECT DEVELOPMENT DRAWINGS

Maintaining the relationship between the Project Development copy and the original drawing

number and revision from which it was derived is important and will:

a. ensure all versions are clearly identified in the Drawing Management System;

b. reduce the problem of cross-referencing and duplication of information that would occur if

new drawing numbers were assigned.

It is possible to have multiple concurrent Project Development copies created from the same-base

drawing. As such it is important that there is strict control over the allocation and management of



Drawing Management

ES-14-101-02



the different versions. If different parties are involved, the Responsible Officers shall communicate

to ensure there are no potential conflicts or interface problems.

For details on numbering “Project Development” drawings, refer to CSBP Engineering Standard

Drawing Numbering (ES-14-101-04).

10.3 CONTROL OF PROJECT DEVELOPMENT DRAWINGS

Each Project Development Copy is subject to the same approval process that applies to any new

drawing. It shall have Alpha revisions during the preliminary design stage.

After approval has been given to proceed with the modification detailed on the Project

Development version, the project development version shall be “merged” with the original base

drawing record. The revision level of the drawings shall be incremented by one and the change

noted in the revision column and signed off.

Note: All other Project Development CAD drawing files showing alternative proposals that

have been rejected should be deleted following the transfer of information to the original

base drawing record. It is acceptable to hold Project Development drawing files in the

drawing repository as a historical record of the alternatives that were considered. A note

should be added to these drawings stating that the drawing is for historical record only.

Note: If the Project Development drawing is merged with the original drawing before

construction commences, the updated drawing will not correctly show what is actually

installed. To avoid this problem, Responsible Officers may elect to defer merging the

Project Development version with the original drawing until after construction is

complete. In this case, the Project Development version should be revised to "Approvedfor Construction" status and used for construction.

11. RELEASE OF EXISTING DRAWINGS FOR MODIFICATION

11.1 GENERAL

All "original" drawings released for updating shall be checked out in the Drawing Management

System and the details of the person who has possession of the "original drawing" shall be recorded

in the system.

11.2

IN-HOUSE RELEASE

The Draftsperson shall Check-Out the drawing file from the Drawing Management System noting

in the system that they have the drawing out for revision.



Drawing Management

ES-14-101-02



11.3 EXTERNAL RELEASE

The responsible officer shall give a member of the drawing office a list of the drawings required to

be released externally so those drawing files can be Checked-Out in the Drawing Management

System, noting the name of the person and organisation to whom the drawing files are being issued.

Note: Any request received by the drawing office directly from a Consultant or Contractor shall

be referred to the Responsible Officer for authorisation before any drawing is released for

updating.

11.4

DRAWING TRANSMITTAL ADVICE

When drawing files are being released to external parties, the drawings should be accompanied by

a “Transmittal Advice” form (PF0031) listing all drawings sent.

12.

FILES

12.1 FILE NAMING CONVENTION

All drawing files shall have a file name as follows.

Note: File Name shall not be reduced in size by removing zeros or dashes.

EXAMPLE 1: NEW DRAWING

Drawing Number: 1162-9-9052/001

Draftsperson carrying out the work and retained on the assigned network drive until the

project development stage is complete.

Note: File names of externally produced Project Development drawings do not have to comply

with above convention, as electronic files of these drawings are not required by CSBP.

Once the Project Development drawing is “merged” with the original base record as per

Section 10, the hand-over drawing shall have a file name in accordance with EXAMPLE

1.

12.2 DRAWING FILE DELETION

Drawing files held in the Drawing Management System are never deleted.

Drawing files of development drawings stored in the draftsperson’s Computer shall be managed bythe draftsperson and deleted if no longer required or uploaded to the Drawing Management system

if considered to be of some use in the future.

13. DRAWING REVIEW AND APPROVAL CYCLES

13.1

INITIAL CHECKING

At the drafting stage prior to submittal to the Responsible Officer for review and approval, all

drawings shall be thoroughly checked for accuracy and compliance with appropriate standards. A

marked-up print shall be returned to the original Draftsperson for back-drafting. The drawings shall

be updated and reissued for further review or acceptance.

Note: The person who produced the drawing shall not check the drawing. Checking shall be

done by someone else who has the appropriate skills.

13.2 REVIEW AND APPROVAL BY THE RESPONSIBLE OFFICER

13.2.1 In-House Drawings

Once the checking process is complete, the Draftsperson shall provide the drawing to the

Responsible Officer for review. After review by the Responsible Officer, marked-up changes will

be returned to the Draftsperson for back-drafting.

13.2.2 External Drawings

Once the drawing has completed its own internal review / approval cycle, Consultants, Contractors

and Vendors shall submit in electronic form each drawing requiring CSBP review, together with an

updated copy of the “Project Document Control Chart”.

After review by the CSBP Responsible Officer, if any changes are required, drawings shall be

marked up to show the required changes, and returned to the Consultants, Contractors or Vendor

for back-drafting.



Drawing Management

ES-14-101-02



The drawings shall be updated and reissued to the CSBP Responsible Officer for further review,

approval or acceptance as required.

Note: Vendor drawings will only be reviewed and accepted if they are “CERTIFIED

ACCURATE” by the Vendor.

13.2.3 Review Status - Consultant and Contractor Drawings

APPROVED Proceed with the work as shown on the drawing. No further approval

required.

APPROVED EXCEPT AS NOTEDProceed with the work as shown on the drawing. Revise drawing as noted

and resubmit for approval.

NOT APPROVED Revise as noted and re-submit for approval. No work shall commence. Anyfurther work including shop or site work commenced prior to approval of the

re-submitted drawing will be at the Contractor’s own risk.

13.2.4 Review Status - Vendor Drawings

ACCEPTED Proceed as submitted. No further approval is required.

NOT ACCEPTED Drawing is not acceptable in the form submitted. Revise and re-submit

drawing.

13.2.5 Responsibility

Drawings will only be approved or accepted by CSBP as to arrangement and conformance to the

specifications and related drawings. Approval or acceptance shall not be construed as relieving or

mitigating the Contractor, Consultant or Vendor of its responsibility for dimensional accuracy,

adequacy and suitability of materials and / or the equipment represented thereon, or for compliance

with contract requirements.

13.3 CSBP IN-HOUSE REVIEW

Once the In-house or External drawing has been checked and the Responsible Officer is satisfied

that the drawing reflects the design requirements, drawings shall be issued by the Responsible

Officer to the Customer and other parties as applicable for review and comment.

Marked up drawings shall be returned to the Responsible Officer for further action. Agreed

changes are to be submitted to the originating drawing office for amendment.

Note: Copies of all drawings showing the general arrangement or layout of new plant,

equipment or facilities which are to be constructed or modified, or any other “key”

drawings, shall be submitted to the CSBP In-House Customer for review.



Drawing Management

13.4 IN HOUSE DRAWING APPROVAL

After acceptance of a drawing by all parties following in-house review, a copy of the drawing shall

be issued to the Engineering Manager and, where applicable, to the Safety Manager and Customer

Area Managers for formal approval.

“Tender Issue” and or “Approved for Construction” drawings require formal sign off in the primary

authorisation section of the title block. Subsequent revisions normally only require the approval

signature of the Responsible Officer in the Revision column.

In the case for Electronic approval through the Drawing Management System the Draftsperson

must fill in the title prior to uploading because on approval this becomes the original drawing.

Refer to Appendix 1 and 2 for guidance on drawing levels and signatories.

13.5

STATUTORY AUTHORITY APPROVAL

Statutory Authority Approval requirements vary between projects. The Responsible Officer shall

coordinate activities and gain approval of relevant drawings in accordance with applicable

procedures.

Where required, the Contractor shall obtain approval from the relevant Statutory Authority. A copy

of any such approval shall be forwarded to the Responsible Officer at the time of drawing

submittal. The Statutory Authority’s approval may take the form of a stamp on the Contractor’s

working drawings. The Contractor will be responsible for obtaining final certificates and arranging

for their correct display.

14. TENDER DRAWINGS

14.1 GENERAL

Tender drawings are those drawings nominated by the Responsible Officer as being part of a

Tender package. They do not require to be revved up to “Tender Issue” status and may be at any

Revision level.

Before they are issued out to tenderers, all prints of all Tender drawings, regardless of Revision

level, should be clearly stamped - above the drawing Title Block wherever possible - “For Tender

Purposes Only”

14.2 APPROVAL SIGN-OFF

All tender drawings shall be signed off by the Responsible Officer and the Engineering Manager

prior to issue out to tender. Refer to Appendix 1 and 2 for details.
