Running number 500-759 to be applied for reinforcement for Checras, Picunche and Huaura.

2.7.2 Civil Drawings, Numbers based on Section of Area

The running number of the formwork and reinforcement drawings shall for some of the main areas (A, B, C, etc) be further divided into subareas.

2.7.3 Electromechanical Drawings, Numbers based on Section or Function Code

The running number of the electromechanical drawings shall be divided into subareas, which reflect the function code of generator, turbine and other electrical equipment.

2.8 Revision Index

To be able to identify the state of the document and whether it is valid for construction, an alphanumeric revision system is used. The revision system is according to Norconsult’s CAD-standard. The letter identifies the state of the document: A → Internal/PreliminaryB → Issued for Information/CommentsC → Issued for IDCD → Issued for Approval by ClientE → Issued for Approval by GovernmentsF → Issued for TenderG → Issued for Fabrication/PrefabricationH → Issued for ConstructionJ → Issued for UseU → DeletedZ → As Built

The revisions are given running numbers (2 digits) after the letter.

Further information regarding the revision status can be found in the CAD-manual.

3 DOCUMENT NUMBERING SYSTEM, PROCESS DOCUMENTS

Documents prepared as part of the process shall follow a different denomination scheme than the formal deliverables described above. The process documents are letters, memos etc. submitted as part of the ongoing work and as partial deliverables prepared prior to the main deliverables.

The naming of the document shall be as follows:

NNFFFYYYYMMDD-O - <Description>

Note: The description does not form part of the document number, but shall be included in the name of the file.

NN = Company Code (NC = Norconsult …)

FFF = initials of the person responsible for preparing the document

YYYYMMDD = year, month, day of submittal

O = Running number of the process documents the document responsible is preparing that day

<Description> = A short text (title) describing the contents of the document

Example doc. no: NCMDW20101114-4Example file name: NCMDW20101114-4-Description_of_document_numbering_system

Process document prepared by Martin D. Westeren, Norconsult, on the 14th November 2010, regarding “Description of document numbering system”. The document is the 4th process document submitted by Martin D. Westeren that day.
