Tips: Main Extension Submittals

1. Template Location (Page 20.0-22 of the CAD Standards)

As stated on Page 20.0–22 of the CAD Standards Manual — Section 20.0 Consultant Needs, all support files can be found on the website.

2. E-Transmit (Pages 20.0-57-61 of the CAD Standards)

Zip files:

a. Issue: one Zip file with multiple folders — When creating Zip files the “path options” should be set to "place all files in one folder," as shown on Page 20.0–59 of the CAD Standards Manual — Section 20.0 Consultant Needs.

Issue: multiple Zip files — All CAD files (drawings) are to be placed in one E-Transmit (Zip file); Page 20.0–57 of the CAD Standards Manual — Section 20.0 Consultant Needs, shows how to accomplish this.

b. CAD files should be free of Proxy objects; when selecting the “file format” with an E-Transmit, choose the option “AutoCAD 2013 Drawing Format with Exploded AEC Objects,” as shown on Page 20.0–59 of the CAD Standards Manual — Section 20.0 Consultant Needs.

3. DWFs (Design Web Format) (Pages 20.0-53 - 20.0-55 of the CAD Standards)

Submitted DWFs sent via Dropbox are multi-sheet, not single sheet:

a. For the Plan Review process, DWFs must be in multi-sheet format — Page 20.0-54, of the CAD Standards Manual — Section 20.0 Consultant Needs shows how to accomplish this.

b. Page 20.0-55 of the CAD Standards Manual — Section 20.0 Consultant Needs defines how the DWFs should be named

DWFs do not contain layers:

a. DWFs shall display the CAD layers used, refer to Page 20.0-54 of the CAD Standards Manual — Section 20.0 Consultant Needs.

4. CTB (Page 20.0-12 of the CAD Standards)

By using Denver Water’s CTB file, many of the other layers do not plot well. Alternately, if Denver Water’s CTB file was not used, the same issues occur with the water layers:

a. Page 20.0-12 of the CAD Standards Manual — Section 20.0 Consultant Needs, Denver Water's provided CTB “shall always be used when plotting”; however, it is understood this may not be effective when other standards are already in place. If this is an issue at your company, you have the following option:

  • In the provided MainExtensions.dwg (template drawing) the layers have been assigned specific linetypes to accommodate for different sizes of pipe. The layer colors may be changed to better fit with other CTB files; however, the pen widths must mimic Denver Water’s Layer Color Chart on Page 20.0-12 of the CAD Standards Manual — Section 20.0 Consultant Needs. Please be advised that the layer colors Denver Water has picked are the standards color codes for the Utility Stake “Call Before You Dig” (blue for water).

b. Denver Water will accept plans that have been plotted using another CTB file as long as the end result is reflective of the standards, as shown on the example sheets (Pages 20.0-37 - 50 of the CAD Standards Manual — Section 20.0 Consultant Needs). This allowance is for Main Extension submittals only. Easements and licenses must use the layer colors and CTB provided.

5. Blocks/Symbols (Page 20.0-34 of the CAD Standards)

Denver Water’s Approved for Construction stamp is old scanned image:

a. The most up-to-date version of the Approved Stamp is now provided in the template drawing; refer to Page 20.0-36, of the CAD Standards Manual — Section 20.0 Consultant Needs.

Dynamic blocks do not work with Civil 3D styles.

a. Denver Water will provide “basic blocks” upon request, [email protected]

Not all water related symbols are represented in the provided template drawing:

a. To request other water related symbols send an email to: [email protected]

6. Linetypes (Page 20.0-9 of the CAD Standards)

Water main linetypes do not match Denver Water’s linetypes.

a. Denver Water does not use a text-based linetype (with a W) for water mains; instead each size of pipe has a distinct linetype. By using the layers provided in the template drawing, the linetypes have been assigned. A .LIN file has also been provided; refer to Page 20.0-9 of the  CAD Standards Manual — Section 20.0 Consultant Needs.

7. Existing Features

Q: Is it required that all existing water features follow Denver Water’s layering and symbol standards?

a. Yes. Denver Water requires ALL water facilities to comply with the CAD Standards. Denver Water’s layer names are based on the NCS (National CAD Standards), with the addition of pipe sizes — this is required for both proposed and existing. If new layers need to be created for existing features, refer to Page 20.0-25 of the CAD Standards Manual — Section 20.0 Consultant Needs.

b. The NCS prefix of “V” is acceptable for Survey/Mapping layering, so long as the layer names include the pipe size using the correct linetypes. Denver Water suggests providing third party surveyors with the CAD Standards.

Note: No variance will be granted for legacy base files with existing water features that do not meet the current CAD Standards requirements.

8. Legend & Abbreviations (Page 20.0-39 of the CAD Standards)

Legend and/or abbreviations not on cover sheet:

a. As stated in Section 2.05.B.1.e, of the Engineering Standards, 14th Edition, “a list of the abbreviations and symbols” must be shown on the cover sheet.

b. Page 20.0-39 of the CAD Standards Manual — Section 20.0 Consultant Needs gives an example of what this may look like, and states “WATER RELATED SYMBOLS PROVIDED IN TEMPLATE DRAWING.” This statement is referring to the symbols/blocks as shown on Page 20-35 of the CAD Standards Manual — Section 20.0 Consultant Needs — abbreviations are not provided in the template drawing. The exact legend as shown on the example sheets is not required, Denver Water only requires the water-related symbols to be incorporated into the legend, and any used abbreviations to be included.

Proposed and/or existing water mains were not shown on legend:

a. The legend should reflect all pipe sizes shown on plans, using the specified layers and linetypes from the CAD Standards. Proposed and existing should appear the same graphically, with the existing screened as per Page 20.0-25 of the CAD Standards Manual — Section 20.0 Consultant Needs.

9. Standard Audit Report (Standards Checker) (Pages 20.0-13-22 of the CAD Standards)

Not included:

a. Pages 20.0-13-22 of the CAD Standards Manual — Section 20.0 Consultant Needs describes the Standards Checker. Page 20.0-64 of the CAD Standards Manual — Section 20.0 Consultant Needs states it is required for each submittal.

Shows errors when ran against drawings:

a. This will almost always show errors, but will not be used against the submitter in any way; Denver Water is using it to assess what is working well within the standards.

Is not working:

a. The Standards Checker (.chx) file was created with a 2013 format of AutoCAD and may not work with earlier versions of CAD.

10. Engineering Standards Drawings Details

Q: Where are the CAD files for the Standards Drawings?

a. The Standards Drawings are not provided in DWG format; PDFs can be found in Engineering Standards, Standard Drawings.
