1. PURPOSE The purpose of this instruction is to describe the procedures to be followed in the management and production of electronic drawings, produced by Consultants for Structures Engineering Main Roads Western Australia. 2. SCOPE This procedure shall apply to all electronic drawings of all structures produced for MRWA by Consultants.

3. REFERENCES The following documents relate to this procedure

• Structures Engineering Management System Manual 3912/01 • Structures Engineering Drafting Information & Practices Manual 3912/04 • Structures Engineering Standard Drawings Manual 3912/07

4. DEFINITIONS The following terms used in this procedure have the specific meanings indicated:

• Designer: The Engineer or Consultant who carried out the design for the structure

detailed in the drawing or the person or body supplying information such as survey control or electrical.

• SES: Senior Engineer Structures

• SISM: Structures Information & Standards Manager

• PO: Project Officer


5. PROVISION OF DATA TO STRUCTURES ENGINEERING “Autocad” is the Main Roads Western Australia CADD platform. Currently Structures

Engineering operates Autocad 2004. Consultants are to ensure the their CADD system can produce electronic copies of the

drawings in a format compatible with this version of Autocad. Structures Engineering’s requirements for all other drawings supplied are that they are to be in Autocad R12, R13, R14, R2000 or R2004 .DWG format only. Where another CADD system is used, it shall be the responsibility of the Consultant to supply all drawings to Structures Engineering in an Autocad R12, R13, R14, R2000 or R2004 .DWG format only. No raster images shall be included in the data delivered to Structures Engineering. CADD drawings shall be provided as above in electronic format, on Floppy diskettes of 3.5-inch 1.44Mb Dos Format, on CDROM or Email. The drawings shall comply with the standards referred to in this manual. No manual updating of CADD drawings is allowed. 6. PROVISION OF DATA TO THE CONSULTANT

Structures Engineering shall provide the following files for the use of Consultant. File Description A1_tblk.dwg A1 size (841x594) base drawing with Structures Engineering’s Consultant title block, standard text style, layers and dimension style. A2_tblk.dwg A2 size (594x420) base drawing with Structures Engineering’s Consultant title block, standard text style, layers and dimension style. Standards Block.zip Pkzip file of all Structures Engineering’s standard drawing blocks. A1 Client.zip Pkzip file of all Structures Engineering’s A1 standard drawing sheet Client Regions blocks. A2 Client.zip Pkzip file of all Structures Engineering’s A2 standard drawing sheet Client Regions blocks. Setdimb.lsp Lisp file that can be load into the Consultant’s drawings to set the dimension style to Structures Engineering’s dimension style “bridge”. Both the A1 and A2 base drawings can be downloaded from the Main Roads web site from the following link: Presentation Drawings


7. DRAWING PRODUCTION STANDARDS 7.1 Drawing Layers Line colours and types shall be set to “By layer”. Drawing layers shall be as detailed

in Appendix A. 7.2 Pen Colour Only Autocad colours shall be used 1, 2, 3, 4, 5, 7,8 & 9. All pen colours are to be set

by layer only, all shall conform to pen colour table, refer Appendix A. The colour table for monochrome plots can be downloaded from the following link: - Monochrome Colour Table

7.3 Text Fonts and Style Only standard Autocad text fonts, as supplied with Autocad package are permitted.

All text in the drawings shall be ISO style (ISO3098B font for R12 users, ISO9 font for LT users and ISOCP2.shx font for R13, R14, R2000 and R2400 users) on layers T25 to T70 throughout the drawing. Both Mtext and single line text are acceptable.

All text styles shall be defined with a height of “0”. N.B. – All special fonts used in the production of drawings are to be supplied by the

Consultant, i.e. any special fonts used in Consultant Logos. 7.4 Hatch Patterns Only standard Autocad hatch patterns, as supplied with Autocad or “Autohatch”

patterns shall be used. 7.5 Line Types and Line type Scale Only standard line types, as designated by “acadiso.lin” shall be used. LTScale shall be set to “0.5”. 7.6 Dimension Style

Structures Engineering’s dimension style is “Bridge” as supplied with the standard consultant drawing sheets. The “dimassoc” variable is set to “0”. The Consultant may varied the “dimassoc” variable to 1 or 2 but all final drawings must be supplied “plot ready” at 1 = 1 plot scale, therefore all dimension text values are to be over-written or dimension are to be exploded before rescaling to plot scale. Final drawings at 1 = 1 plot scale are to be “dimension update” to ensure that all dimensions present correctly. The “bridge” dimension style can be inserted into Consultant drawings by loading and running the “setdimb.lsp” lisp provided. Setdimb.lsp


7.7 Model and Paper Space All drawings supplied to Structures Engineering shall be in “Model Space” only. Under no circumstance are “Paper Space” drawings to be supplied to Structures Engineering.

7.8 External Reference Files (Xref)

Drawings supplied to Structures Engineering shall not have external reference drawing files attached. Consultants may use external reference drawing files in the production of their preliminary drawings but final drawings presented to Structures Engineering must have all external reference files bound, clipped and trimmed to the limits of the drawing sheet at final handover. All external data is to be erased and purged from the drawing. 7.8.1 Binding of External Reference Files Upon completion of the project and before drawings handover to Structures Engineering the following procedure shall be implemented for all drawings containing external references.

• If Xref’s are Xclipped then set the Xclipframe toggle to 1. • Make a new layer called “Xclip” and set it to current. • Lay a new polyline or rectangle tracing the Xclipframe. • Choose Insert >Xref Manager. • Then select the required Xref file to be bound and select Bind, of the two options given, select bind. Repeat until all Xrefs are bound.

The external reference files are now part of the current drawing.

7.8.2 Trimming the External Reference Files

For the trimming and removal of all extraneous Xref items from the drawing implement the following procedure.

• Explode all Xref blocks. • For Autocad R2000, select from the Bonus menu bar Modify > Cookie Cutter trim or for Autocad R2004, from the command line type “Extrim”. From the resulting command line prompt “select objects”; select the boundary previously drawn on the Xclip layer. From the command line prompt “Specify the side to trim”, select a point on side objects are to be trimmed from. All objects crossing boundary will be trimmed. • All other entities still outside the boundary can be erased. • The Xclip layer can be turned off. • Type “purge” at the command prompt and purge all items.

Save the drawing. The drawing is now suitable for handover to Structures Engineering.


8. DRAWING COMPLETION STANDARDS 8.1 Delivery

• Only structures “30” series drawing numbers shall be used on structural drawings. (0430-0129 refer to SISM for drawing number allocation).

• Drawings to be “.dwg” file, with all preliminary linework/details removed from the extents.

• Drawings shall be supplied “plot ready” at a 1 = 1 plot scale. All un-referenced blocks, layers, styles and linetypes shall be purged. Drawings to be saved at extents with the lower left corner of the titleblock at 0,0 coordinates.

• All drawings shall be supplied in “model space”. “Paper space” entities are not acceptable.

• Current menu referenced by drawing shall be “acad”. • Current style referenced by drawing shall be “iso”, fontfile = ISOCP2.shx. • Completed drawings shall be supplied electronically accompanied by a final

fullsize, signed (including regional client titleblock signatures) and dated monochrome plot.

• Hard copy plots shall be produced to pen thickness/colour assignment standards as detailed in Appendix “A”.

• Electronic drawings can be supplied to Structures Engineering in a compressed .ZIP format using PKZIP

8.2 File Naming Standard Files in “.dwg” format shall be named to drawing number, without Amendment

number component. eg: 0430-0263-4 should be supplied electronically as 04300263.dwg. 9. STANDARD DRAWINGS 9.1 Standard Drawings Manual Standard drawings may be obtained on request in hard copy and electronic .dwg
