1. Purpose

This procedure covers the requirements to ensure that the applicable specified design bases, regulatory requirements, codes and standards (further referred to as "basic design data") are correctly translated into relevant job documents.

2. General

None.

3. Responsibilities

The Project Manager has the final responsibility for the conformance of the project documentation to basic design data. He will be responsible for the validity of the design data as used and the maintenance, updating and distribution of the data to lead men participating in the project.

4. Procedure

4.1 General

The following types of basic design data must be available for project execution (see also ref. 6.5 and 6.6):

1. General information:A. Client and project
   B. Local area and site

2. Client requirements:A. Data for process engineering
   B. Engineering and Design standards
   C. Design codes
   D. Engineering details
   E. Equipment preferences or pre-selections

3. Site conditions for design:A. Atmospheric
   B. Conditions above grade
   C. Conditions below grade
   D. Conditions at battery limits
   E. Offshore (see Attachment 1)

4. Utilities for plant operation

5. Special and offsite facilities required

6. Environmental requirements

7. Authority requirements (other than environmental aspects)

8. Procurement

9. Site conditions for construction

4.2 Collection and Presentation of Basic Design Data

With the variety of projects in size and type, the range and depth of information supplied by the client will vary as well. The collec tion of basic design data will differ for each project but the following phases must be implement to improve the quality of Company's efforts.

1. Basic Design Data sheets must be as completely as possible starting in the proposal stage and must be based on data supplied by the client and data collected from our own or public and/or governmental sources.

2. A site visit must be made to discuss the missing data on location by knowledgeable Company representatives.

3. After the site visit the Basic Design Data sheets must be filled out as required for the project and distributed to all lead men participating in the project in accordance with a pre-set distribution list.

4. The Project Manager will review the Basic Design Data sheets periodically in estimate/proposal and the execution job phases and reissue after any change.

4.3 Changes to Basic Design Data

Any change to the Basic Design Data can only be authorized by the Project Manager after required consultation.

Changes must be marked-up in accordance with procedure ref. 6.4.

The issue descriptions of the Basic Design Data sheets must conform to descriptions used in the Procedure for Production of Engineering Documents, ref. 6.3.

5. Flowchart

None.
