1.0 PURPOSE

The purpose of this procedure is to provide guidelines for:

• The correspondence coding system.

• The document numbering system.

• The drawing and specification numbering system

• Logging, distribution and filing of project related outgoing, incoming and internal correspondence

• Logging, distribution, reviewing, issuance of comments, approval and filing of Contractor prepared engineering documents

Note: E-Mails are not to be used for formal, contractual matters between Company and Contractor. However if an important or significant e-mail is produced or received during the course of the Project the originator or primary recipient is responsible for printing a hard copy and sending to file.

Upon project completion, all relevant information must be compiled in Jakarta head office to satisfy operational, legal and statutory requirements. Compliance with these guidelines will allow this to be carried out in a timely and efficient manner after the records have been transferred from the various site locations to the Jakarta head office.

2.0 SCOPE

The scope of this procedure extends to all correspondence and engineering documents generated during the ADGF Project.

3.0 RESPONSIBILITIES

These guidelines will be followed by all Company and Contractor project personnel at all site locations so that records and information are indexed, stored, distributed and made available to users in an efficient and cost effective manner.

Note: Contractor shall be responsible for the review, revision and re-issue of all drawings re-numbered to meet the requirements detailed in Section 7 of this procedure.

4.0 DEFINITIONS AND ABBREVIATIONS

Not Applicable

5.0 CORRESPONDENCE CODING

5.1 Purpose

To define the correspondence coding system to be used on all outgoing and incoming correspondence generated and received during the ADGF Project, including letters, faxes, memos and transmittals etc.

5.2 Procedures

The structure of the document coding shall be as follows:

5.2.1 Outgoing Correspondence: 84506-X-NNNN

¨ 84506 is the ADGF Project Code assigned by the project group in Houston

¨ “X” is the Document Type where :

¨ L = Letter

¨ F = Fax

¨ M = Memo or Interoffice Communication

¨ T = Transmittal

¨ D = Document / Drawing Transmittal

¨ “NNNN” is the Sequential Number for each item of outgoing correspondence

Note that blocks of numbers will be issued for correspondence originating from each Project Office / Site Location as follows:

0001 – 0999 ADGF Jakarta Office

1000 – 1999 Site Office 1

2000 – 2999 Site Office 2

In the event that an office location uses all the assigned numbers, the next available ‘000 series will be assigned to that location.

Example - Correspondence Out - 84506-L-0066

84506 (Project ID) - L (Letter) – 0066 (Document number 66 in the unique sequence).

5.2.2 Incoming Correspondence

Incoming correspondence will be logged on receipt in the “ADGF Incoming Correspondence Log” and assigned a unique number by the system.

After logging in the system, incoming correspondence will be stamped with the following details:

¨ Distribution (Addressee for action plus copies for information to appropriate Team members)

¨ Project File Code Number (ADGF Project uses the 19.0 Series)

¨ The unique number assigned by the Incoming Correspondence log system

The Document Controller will then distribute the document copies as appropriate – originals to be filed in the correct Project File.

5.3 Distribution Matrix

Distribution of correspondence shall be by the approved distribution matrix. This matrix will assign the primary action and distribution of incoming correspondence, reports and minutes of meetings.

Each ADGF Project office shall develop their own distribution matrix in accordance with their particular requirements.

6.0 DOCUMENT NUMBERING

6.1 Objectives

To define the document numbering system to be used on documents such as procedures, reports, studies etc. produced for the ADGF Project. Note that Drawings and Specifications are numbered using the system detailed in Section 7.0

6.2 Policies

All “internal” CIIL Project Control Procedures will be numbered using an abbreviated system so that unnecessary zeros are not incorporated in the document number e.g. IFR/PS/PR/84506-00-001

If a Procedure is issued to a Contractor as part of the Bid documentation, then the Procedure will be renumbered using the full ADGF document number, e.g. IFR/PS/PR/84506-0000-00-001. This will ensure consistency with the numbering system used for Drawings and Specifications that are also issued externally.

6.3 Procedure

All documents detailed in Section 2.4 will be numbered in accordance with the following system:

ADGF DOCUMENT NUMBER

IFR – SS – TT - 84506 - BB - XXX
							Sequential Number

							System Code ID Number

							Project ID Code (84506)

							Document Type

							Functional Area

							Infrastructure Ref. (IFR)

IFR is the Infrastructure Group Reference

SS is the Functional Area Code e.g. “PE” – Project Execution

TT is the Document Type e.g. “PR” - Procedure

84506 is the ADGF Project Code issued by the Project Group in Houston

BB is the System Code e.g. 31 - Manifolds. (Appendix A1.2)

NOTE: Internal CIIL Project Control Procedures are ALL numbered “00”

XXX is the Sequence number of the Document, starting at 001

Electronic document files shall be saved as the document number with a suffix denoting the revision status (e.g. IFR/PS/PR/84506-00-001-A for revision A).

6.4 Functional Area Code

This identifies the Functional Area within Infrastructure group who prepared the document, where:

MA - Management

DE - Development Engineering

PE - Project Execution

QA - Safety, Environment and QA

PS - Project Services

GR - Government Regulations

OP - Operations Planning

6.5 Type of Documents
