G. Industry Codes and Standards The industry specifications/codes/standards applicable to this PROJECT shall be latest editions at the time of execution. These Codes and Standards will not be provided by the COMPANY:

2.09 Standard Guidelines for Preparation of As-built Drawings

1. General

1. The CONTRACTOR shall provide all drawings required for this PROJECT

covering all the substations involved in accordance with the requirements of the COMPANY Engineering Drawing Preparation Standards (SEEDS-II revision-01).

The drawings shall be assigned with drawing numbers and indexed as outlined in the above procedure. A block of drawing numbers shall be provided by the COMPANY for all new drawings/documents.

2. Drawings shall be of uniform size in each discipline as much as possible and ISO scales hall be 1:10, 1:50, 1:100. 1:1200 etc.

3. The existing system drawings of the source substation are generally available with the COMPANY in digital or tiff format except in certain cases where it is in the form of hard copies. Copies of existing available drawings shall be provided on CONTRACTOR'S written request. However, if any related information is not available, the CONTRACTOR shall be responsible to develop all the required drawings to satisfy the PROJECT requirements.

4. The drawings involving modification/expansion of the existing system in source substation shall cover the details of the existing system and interface. The drawings in general shall be computer drafted and compatible with Micro Station V8i or above version software computer-aided-design (CAD) system. However, in case of drawings involving modifications to existing drawings, which are not available in digital or tiff format CONTRACTOR shall be responsible to develop all the required drawings.

5. The drawing to be submitted by the CONTRACTOR shall be of the following standard sizes in accordance with SEEDS-II revision-01.

A-Size sheet, 711x1016mm or (28x40 in.) B-Size sheet, 508x711 mm or (20x28 in.) C-Size sheet, 356x508 mm or (14x20 in.) D-Size sheet, 279x432 mm or (11x17 in.) E-Size sheet, 211x297 mm or (8.27x11.69 in.)

2. Revision of Existing Drawings/Drawing Control Sheets

a. All existing drawings including common drawings affected by this PROJECT shall be revised and submitted for COMPANY review as part of CONTRATOR'S design submittals. The drawings in general shall be computer drafted Micro Station V8i or above version software in accordance with SEEDS-II revision-01.

b. For modification WORKS of existing substation, the existing drawings only shall be revised as far as possible. If revising the existing drawings are not feasible or not practical and new drawings need to be developed, then preferably the same number with additional/different sheet number shall be allotted. New drawings having new drawing numbers shall be created only if drawings of existing system are not available.

c. The drawing involving modification/expansion of the existing system in substation shall cover the details of the existing system and interface. Drawings giving only the isolated views/information of expansion/modification work without details of existing system/interface are not acceptable. If new drawings, developed for modification work of existing system do not cover the complete details of existing system, then the corresponding existing system drawings shall also be modified to show the interface/integration with the new drawings developed, and submitted for COMPANY review as part of CONTRACTOR'S design submittal.

d. The existing drawings are listed in the drawing control sheet(s) for the substation and covered in more than one (1) drawing control sheet for each of the affected existing substations. The CONTRACTOR shall review/study these various by drawing control sheets and drawing, identify the superseded/latest drawings and if necessary carry out field verification to ascertain the correctness of the existing drawings. Only the appropriate/ correct drawings shall be used for developing the drawings for modification WORKS, While modifying any existing drawing sheet, the sheet will be submitted in duplicate, one marked as existing and the other marked as ' modified'. All the existing drawing control sheets shall be revised to reflect the new revision numbers of existing drawings revised and to identify the superseded drawings. Also a prominent note shall be put on the revised existing drawing control sheet (s) to indicate the new drawing control sheet number, if a new drawing control sheet was developed. (e.g. "See drawing control sheet * E-xxxxxx for list of drawings developed for C. N. # xxxxxxxxx for ………).

e. Contractor shall not change/modify the drawing sheets of existing drawings. If additional sheet(s) are required to be added, the same shall be done using an alphabet. For example, a new sheet is to be added after sheet 5 of a drawing number EA-467898 with 20 sheets, then, its sheet # shall be sheet 5A of 20.

DGN format other than the NG requirements. All existing drawings affected by this PROJECT shall be revised and corresponding existing drawing control sheets shall be updated by the CONTRACTOR. The existing drawing control sheet shall be updated and automated in XLS format. If the existing substation drawings do not have drawing control sheet, then the CONTRACTOR shall prepare new Drawing Control Sheet, which shall include the new and existing drawings. CONTRACTOR shall coordinate with COMPANY for the list of the existing drawings. All Drawing Control Sheets, listing all proposed and existing drawings shall also be submitted in the Base Design submittal.

2. All revisions shall reflect field modifications to engineering flow diagrams, electrical one line diagrams, electrical schematic connection and interconnection wiring diagram; instrument hook-ups wiring diagrams, terminal connections, dimensioned equipment layouts, all underground installations and other WORK and facilities not normally visible. The CONTRACTOR shall provide "As-Built" drawings showing all field modifications to drawing and diagrams prepared by the Vendors and SUB-CONTRACTORS.
