2 Glossary

General drawings Drawings which are not linked to a specific station or line. Autodesk Name of the company that produces the AutoCAD tool. Basic templates Templates for telecoms drawings. As a rule in tabular form. Sheet number The drawings have a sheet number in addition to a drawing number. Construction documents Drawings that apply before and during the construction of an installation (“for construction”). Document pouch Excel list with a database link. Used for lending out drawings from Swedish National Grid’s database (Banken). Document status Shows if the document/drawing is designated for inspection, is in the construction phase or is a completed as-built document. Format number Refers to the print-out/paper format, a prefix in Swedish National Grid’s drawing number. Design documents Drawings, documents and technical data (TD) that are to be inspected, or are in the design or construction phase. Group number Classification of the drawing based on its function. The group number also acts as a search term in Swedish National Grid’s database. Documents Documents which are not drawings or technical data, e.g. environmental documentation, apparatus sketches, data sheets, manuals, self-inspection records, FAT, SAT, etc. Principal The company that owns shared equipment and the premises where the installation is set up. The principal also administers the drawings. Supplier A generic term for contractors, subcontractors, suppliers, project planners and others who supply documentation. Serial letter Designation for a specific installation, line or station. Also at apparatus level (primary apparatus)/installation level (e.g. busbar)


7/23

Cancelled = deleted and not replaced. A cancelled drawing that no longer applies. Location-specific drawings Drawings pertaining to a specific station or line with a unique number. See “Site number”. Site number A site number is used to link a drawing to a specific installation. As-built document Drawings or documents showing the completed result “as built”. Drawings Documents set up in Swedish National Grid’s drawing frame with a drawing header and drawing number. Drawings list List of all the drawings for a station or line. Drawing header The drawing header, which is located at the bottom right of the drawing frame, contains the station name, line name etc. for a specific version. See Section Fel! Hittar inte referenskälla.. Drawing frame Lines on the outer edge of the “sheet”. The drawing is produced inside these lines.


8/23

3 General requirements

The overall requirements for drawings are that they shall be clear, easy to read and

understand and adapted to Swedish National Grid’s documentation system. The

drawings shall also be easily legible after being printed out in a size smaller than the

original. Swedish National Grid is entitled to determine whether the requirements are

met. The supplier shall supply test drawings upon request. These shall include all types

of drawings within the scope of the delivery. The documentation shall be produced

according to Swedish National Grid’s requirements and guidelines.

Any divergences from these requirements must be approved in writing by Swedish National Grid.

3.1 Provision of drawing frames and templates All drawing frames and templates are always supplied by Swedish National Grid’s

documentation unit, even if Swedish National Grid is not the principal.

3.2 Drawing header Drawings whose header has been changed will not be approved. This is because

Swedish National Grid’s drawing headers are linked to its database, and this linkage

cannot be ensured if a header has been changed.

The way in which data is entered in the drawing header may differ between technical

sectors, but this must be done as shown in the example in Annex A.

3.2.1 Drawing numbers

Drawing numbers shall be made available by the documentation unit, even if Swedish

National Grid is not the principal. Each drawing number comprises a 7-digit number

preceded by a format character.

3.2.2 Revision/change notification

Documentation supplied during a project shall include a revision letter (A, B, C, …) to

show that it is not an “As Built” revision.

No revision changes may be made in the as-built documents submitted to the customer

as the final documentation, i.e. the change notification shall be empty.

Documents changed after the final documentation has been delivered shall include a

revision number (1, 2, 3, …)

3.2.3 Site and group numbers

The site and group number must always be specified, as this information constitutes a

search path for the drawings in the document system.


9/23

Each installation has a site number which can have two to four digits. Lists have been

drawn up of the site numbers for the installations. Site numbers for new installations

are designated by Swedish National Grid.

The group number designates the function in the installation to which the drawing

refers. The group numbers are set out in specific group number lists. Swedish National

Grid designates which group number list shall apply to each station and line.

3.2.4 Company name

The company name shall always be entered by whoever creates the drawing.

3.2.5 Company logo

A contractor’s company logo may be placed solely where agreed between the

contractor and Swedish National Grid’s document manager.

3.2.6 Document type

The document types to be used are being examined and have not yet been designated

in this version of TR08-02. Until further notice, the document types in “Annex B” shall

be used; any divergences from this shall be agreed with Swedish National Grid. The

formats indicated by a cross (”X”) are mandatory, i.e. wherever a cross is placed, e.g.

DWG and PDF-A, deliveries shall be made in both formats.

3.2.7 Document status

The document status shows where the document is located in its life cycle. The status

is specified in UPPER CASE as shown below:

DESIGN DOCUMENT

CONSTRUCTION DOCUMENT

AS-BUILT DOCUMENT

4 Technical points relating to new drawings

4.1 General Approved formats are .dwg (AutoCAD) and .xlsx (Excel).

4.1.1 File name

The file name shall comprise Swedish National Grid’s drawing number, without any

preceding format characters. The drawing number shall be followed by sheet number

and revision.


10/23

E.g. drawing sheet 1: The construction document file name is: 4009787_0001_revA

The as-built document’s file name is: 4009787_0001

A revised as-built document’s file name is: 4009787_0001_rev1

4.2 CAD drawings External references “xref” must not be used. All elements must be editable in the basic

version of AutoCAD.

All layers shall be activated, with the exception of the circuit diagram, where auxiliary

layers are permitted and shall be deactivated.

In addition, drawings shall be cleared via a purge command. Use the “Zoom Extents”

command to check that no unnecessary elements are present outside the drawing

frame.

4.2.1 File format

Unless otherwise agreed, drawings shall always be supplied in the Autodesk dwg-

format in the version of AutoCAD which applies within Swedish National Grid’s

standard installation at the time of the contract.

4.2.2 Drawing frame

Each drawing file shall contain only one drawing frame/sheet, i.e. it is not permitted to

draw several sheets in the same file.

The following drawing frames apply:

A1.dwg

A1S.dwg (portrait A1)

A2.dwg

A3.dwg

A4.dwg

A4L.dwg (landscape A4)

Basic templates for telecoms documentation (.dwg)

Drawing frames must NOT be changed, i.e. exploded, and “saved as” or linked to other

blocks.

The latest version of the drawing frame shall be used for every new drawing. No

information may be placed outside the drawing frame.

4.2.3 Name on the drawing frame

The drawing frame’s name is located in the template supplied by Swedish National

Grid, and is shown on the dialogue box “Enhanced Attribute Editor” in AutoCAD. The

frame shall have one of the following designations, depending on the drawing format:


11/23

A1, A1S, A2, A3, A4, A4L

NB. The frame’s name must not be changed. If the name is changed, the dwg file

cannot be automatically scanned into Swedish National Grid’s Banken document

system.

4.2.4 Layers

The following layers accompany the drawing frame and must not be used for other

information.

Layer content Layer

Drawing frame with all text “Bl”

Crop marks “Marg”

Other information is to be located in other layers where the supplier has free access.

4.2.5 Fonts

The ISOCP text format with the ISOCP.shx font file shall be used for text in the

drawing header. Apart from ISOCP, AutoCAD’s other standard fonts are also

acceptable for the contents of the drawing.

4.2.6 Language

As a main rule, all drawings shall be provided with Swedish text. Any exceptions from

this rule shall be approved in writing by Swedish National Grid.

4.2.7 Model space

All parts of the drawing – i.e. the design drawing plus the drawing frame, shall be

located in the model space. (Paper space is not permitted.)

4.2.8 Drawing scale

The contents of the drawing shall be at a scale of 1:1, apart from sections and views.

4.2.9 Plotting scale

All drawings shall always have one (1) main scale, and the drawing frame shall be

scaled up by the same factor. If several scales are to be used, it must be clearly shown

on the drawing which part and what scale apply.

The following main scales shall apply (SS-ISO 5455):

1:1, 1:2, 1:5, 1:10, 1:20, 1:50, 1:100, 1:200, 1:500, 1:1 000, 1:2 000, 1:5 000, 1:10 000

4.2.10 Dimensioning

The dimensioning must not be exploded.


12/23

4.2.11 Lines

The line type scale must be the same as the plot scale on the drawing (“LTSCALE”).

The line thickness is controlled by the “LWEIGHT” variable.

There must not be any free line ends. The end points of two lines that form a corner

must have exactly the same coordinates (Snap = On).

4.2.12 Units

Only SI units are permitted on the drawings. All length dimensions on the drawings

shall be specified in mm.

4.3 Excel documents

4.3.1 File format

Unless agreed otherwise, tables of various types shall be delivered in the Excel format

that applies within Swedish National Grid’s standard installation of Microsoft Office at

the time of the contract.

4.3.2 Document templates

Document templates are supplied by Swedish National Grid’s documentation unit and

must NOT be changed. The following templates apply:

Station:

Cable list

Drawings list

Signage list.

Cabinet documentation:

Signage list

Apparatus list Connection table

Cable parts table (single point).

4.3.3 Cable list

Cable numbers are provided by the documentation unit at Swedish National Grid and

only one cable list may be used per installation.

Different installation parts and technical sectors are assigned their own series of sheet

numbers and cable numbers. The cable number series can vary between different

stations. The sheet and cable numbering to be applied normally is shown in the table

below.


13/23

Example of how the cable list should be set out.

When a cable list is to be created for control installation cables, sheet numbers from

9.1 and cable numbers between 5001 and 9000 are used. (Shown in italics in the table

below.) If the cables are numbered from 5600, for example, this means that the sheet

numbers shall be left “empty”, i.e. leaving room to enter cables 5001-5599 on

previous sheets. This allows changes to be entered on another occasion.

Sheet no. Use Cable number

5 Revision of drawings

Change notifications with numbers shall always be provided.

When existing General Drawings are revised, nothing may be deleted from the

drawings, only additions are permitted. Information may only be removed from site-

specific drawings.

Cable lists are not lent out. The supplier receives a copy of the original into which the

assigned cable number is entered. Text to be entered into the cable list shall be in red

and text to be removed shall be in yellow.

In the event of changes to existing cabinets, the documentation unit should be

contacted.

5.1 CAD drawings The same requirements apply as for new drawings. CAD drawings from AutoCAD

version R10 and up to and including the latest version may be found in Swedish

National Grid’s document archives.

5.2 Excel documents The same requirements apply as for new drawings. Documents from earlier versions of

Excel may be found in Swedish National Grid’s document archives.

5.3 TIFF drawings Scanned drawings are in TIFF format with a minimum resolution of 300 dpi and may

not be changed and rescanned by the contractor. Scanned documents shall be

processed with an image processing programme if required to enhance the quality.

The file name must contain drawing/document numbers and sheet number.

5.4 Physical originals Changes in physical originals must always be initiated by Swedish National Grid.

5.5 Redrawing of originals If any drawings are redrawn, all applicable information from the old drawing must be

transferred to the new one. This also applies to the information in the drawing header,

e.g. “Drawn by”. If a drawing is redrawn, a revision note must be entered with the text

“Redrawn” plus an explanatory text about the changes made. In the event of

redrawing, the physical original shall always be transferred to an electronic form. The


18/23

superseded original shall be returned with a note that the drawing has been redrawn

(not cancelled).

5.5.1 Revision notes

Revised numbering shall be applied (1, 2, 3, …) if any approved as-built

drawings/documents from Swedish National Grid’s archives are redrawn. A revised

lettering code may be found on older drawings, but this shall be translated into

numbers. If, for example, revision C exists, the next revision shall be 4 (not D).

See also the rules for revision notes under Section 3.2.2.

5.6 Cancellation of original drawings Swedish National Grid’s documentation unit always implements cancellations.

Drawings which are no longer valid shall be cancelled. Lent-out drawings which are to

be cancelled shall be returned to Swedish National Grid’s documentation unit.

A cancellation message containing all drawing and sheet numbers in tabular form shall

be created. This message shall be signed by the company with date and name.
