CAD Standards

Denver Water CAD standards are in place to support our core values: integrity, vision, passion, excellence and respect. The enforcement of CAD standards results in clear, accurate drawings that helps Denver Water maintain integrity within the system and to continue to provide reliable service.  Consistent drawings help our field crews identify water features during inspection and construction; increases efficiencies within the office to quickly post work to the GIS (Geographic Information System); and improves the as-built plans creating a more complete, accurate and identifiable set.

CAD standards are just one more way Denver Water can accomplish its goal of becoming the best water utility in the nation. We strive to help our customers and consultants by maintaining a very clear and simple CAD standard for drawing creation. We remain open to questions, comments and concerns regarding the CAD standards and always take suggestions into consideration. 

Denver Water's CAD standards are mandatory procedures for internal and external CAD drafters to follow to create and deliver all CAD drawings. Accurate and error-free CAD drawings support Denver Water’s GIS/E-map system, which is used by nearly every division of Denver Water. Having a standard set of drawings ensures that less costly mistakes are made in the field, in turn saving time, money and sometimes lives. Denver Water maintains safety, reliability and consistency within the system by communicating, clear, accurate information.

Other examples of local municipalities that have and enforce CAD standards are CDOT, Metro Wastewater, Greenwood Village, and City and County of Denver.

FAQs

When do I use Main Extensions?

Distribution Engineering is responsible for the design of proposed projects and the “as built” drawings required for all main installations by Denver Water that are 24 inches and smaller.

Work done within Distribution Engineering is comparable to the Main Extensions submittals, Engineering Standards 14th Edition, Chapter 2.

When do I use Easements and Licenses?

Property Management is responsible for easement acquisitions, plan reviews, land sales and exchanges and license agreements on Denver Water’s operating properties and nonoperating properties. They also oversee recreation activities for operating and nonoperating property, including leases, agreements and studies. Work done within Property Management is comparable to the Easements and Licenses submittals, Engineering Standards 14th Edition, Chapter 4.

When do I use Capital Projects?

Programs and Projects/Design Drafting is responsible for providing Engineering services related to new and existing Denver Water facilities. These services include Capital Projects, scheduling, budgeting, the control of assigned projects, and coordination with other divisions and sections as well as outside agencies.

See the Capital Projects Procedures Manual for CAD Standards compliance on work related to Capital Projects.

10 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.
