What is BIM?
Building Information Modeling (BIM) is a process of planning and collaboration for construction projects that is
facilitated by modern digital technology on a Common Data Environment that provides integrations with other
systems like geographic information systems (GIS) and enterprise asset management (EAM) systems.
BIM supports project development, inter-departmental planning, and key asset data tracking and integration.
Managing documents in a BIM document management system (Common Data Environment) has the following
benefits:
Easy access to design and construction documents in a centralized repository
Document versioning
Model coordination and clash detection
Design and construction issue and markup tracking
Design and construction document approvals
Purpose of Document
This document has been written to communicate requirements for City of Seattle project teams who are
implementing BIM workflows and technology in-house and in partnership with consultants, contractors, and other
agencies. For a list of updates, see change log.

Civil Integrated Management (CIM) provides strategic
planning and support to improve and accelerate project
delivery across City of Seattle departments. The goal is to
align systems and data to support desired business
outcomes through standards and governance.
BIM standards provide the framework to support CIM by
integrating technology and data through the following
teams:
Geographic Information Systems (GIS)
Surveying and Mapping
Engineering
Construction
The map shown on the right illustrates how civil data is
published and made available on the GIS platform for

Steps for Successful Project Delivery
Go over the submittal checklist to ensure standards compliance before submitting deliverables for review.
Become familiar with the CDE, Autodesk Doc, and how to track issues and conduct reviews on the platform.
Learn how to conduct design collaboration and model coordination on the CDE.
Keep Drawings Clean
Be aware that inserting drawings and non-standard blocks may introduce clutter that affects drawing performance.
In Civil 3D®, look for extraneous sites in the prospector and extended data in object properties.
Purge unneeded layers, blocks, text styles, etc.
Proactive Approach to Projects
The goal is to be proactive, efficiently creating deliverables while reducing mistakes. A reactive approach costs more
money and may cause more errors due to last-minute edits and changes.
The graph on the next page illustrates how taking a reactive approach tends to cause delays and is prone to errors,
where-as taking a proactive approach helps teams produce targeted deliverables on time with less errors.

The orange line in the chart shows a reactive approach,
doing minimum work early on and delaying important
design tasks to the end of the project. Problems with this
approach include:
Considerable work is left to the end of the project,
often resulting in mistakes and schedule delays.
Shortcuts are taken to save time, reducing the data
quality.
The project is prone to more change orders and
design changes during construction.
The blue line in the chart shows a proactive approach,
producing targeted deliverables on time. The proactive
approach aims to complete the following work at
standard milestones:
Pre-30%: Develop a 3D base map with researched or
verified depths of underground utilities that may cause
conflicts during design.
30%: Develop sheet index table, create named plan
views and set match line locations for all disciplines in
the X-VIEW drawing and setup sheets.
30%: Create 3D models of proposed features for clash
detection and analysis (model coordination).
60%: Continue model coordination, determine
proposed elevations, and create profiles and/or
sections.
90%: Continue model coordination. Plan set must have
all the elements of the final plan set and only minor
changes should be made to reach 100%.

Authoritative 2D and 3D Drawings
Authoritative drawings must only contain objects related
to the drawing discipline with no extraneous content and
all other drawings must be saved in the WIP sub folder
(learn more).
The BIM Manager must document the list of authoritative
drawings in the Model Progression Matrix in the BIMxp.
Authoritative drawings must follow the file naming
convention according to the type of content contained
within them:
2D drawings (such as roadway hatch patterns) must
only contain 2D linework and annotation that will be
shown on a sheet and printed.
3D drawings (such as sewer or storm pipe networks)
must only contain 3D models and labels that will be
shown on a sheet, referenced into another drawing, or
published to an external system (such as GIS).
Composite Drawings
To increase efficiencies by reducing the number of data
shortcuts in sheets, add data references into a single
drawing for standard stylization and labeling in this
location:
\C-Civil\03-Design\Composite
Example composite utility file name:
[PTN]_3D-UTIL-Composite.dwg
Example composite grading file name:

Sheets and drawings must utilize COS-ROMANS.TTF, a
TrueType Font designed to mimic ROMANS.SHX. External
partners must download this font and install it.
There are two styles with this font:
Regular: a thin lineweight used for screened-back
annotation (such as base maps).
Bold: a thick lineweight for standard annotation.
Using a TrueType font makes PDF files searchable and
lightweight, so they open efficiently.
Plot using DWG to PDF.pc3 to capture the
COS-ROMANS.TTF font and embed it in the PDF so the
font will be displayed for anyone who views the PDF, even
if they don't have COS-ROMANS.TTF installed.

8/30/2024 City of Seattle BIM Standards 36
When drawings that are plotted to PDF, DWFx, or hard copy, color tables (.CTB files) are used to control the plotted
lineweights and colors. Because the City of Seattle uses a TrueType Font, all annotation is unaffected by the color
table lineweight settings.
Primary SPU/SDOT Color Table
COS_CADD_standard.ctb (specific colors are plotted in color to meet APWA standards)
Secondary SPU/SDOT Color Tables

The layer name format is organized as a hierarchy. This
arrangement allows users to select from several options
for naming layers according to the level of detailed
information desired. Layer names consist of distinct data
fields separated from one another by dashes. A detailed
list of abbreviations, or field codes, is prescribed to define
the content of layers. Most field codes are mnemonic
English abbreviations of construction terminology that are
easy to remember.
The layer name format, showing the Discipline Designator,
the Major Group, two Minor Groups (optional), and the
Status (optional) fields looks like this:

Standard AutoCAD Plant 3D® Layers
The City of Seattle uses out-of-the-box AutoCAD Plant
3D® layers, but when plotting, be sure to utilize standard
layer colors to ensure lines have the correct lineweights.
Example colors:
Color 6 plots bold, color 2 plots medium weight, color 1
plots thin, and color 7 is used for proposed annotation.
Export AutoCAD Plant 3D® Layouts to Civil 3D®
Sheets are managed by Civil 3D®, thus all AutoCAD Plant

The coordination prism is a generic model object that contains enough information to substitute for a model, is
located at a defined (relative) working point in the project and is assigned geo-located coordinates, elevation, and
angle heading. This is a geometric wedge with linework on the bottom and placed at the same coordinates in all
working drawings (including civil drawings). This helps to confirm that drawings are aligned and eliminates any
concerns of “something has moved” regarding the XREF. Having a simple object that is identical in all models allows
for quick visual checks on alignment rather than reviewing the data for several points.
The project team must decide what the coordination prism will look like and where it will be placed each model. Civil
3D® must be used to assign the X, Y, and Z coordinates and true north rotation. The coordination prism information
must be documented in the BIMxp.
Coordinates in Facility Models
To display project coordinates in a facility model, follow the instructions below:
Plant 3D®: isometric location and offset rotation…

It is important to plan design views to fit inside the SPU/SDOT title block. The total drawing space within the title
block is 32”x19”. The profile grid takes up 30”x9.
When planning for drawing views, leave about ½ inch space on every side that has a match line and about 1 inch of
space under profile views for station labels. Also, if a legend or notes will appear on the sheet, leave about 5 or 6
inches on the right-hand side.

This tool allows the user to plan drawing views using
common engineering and architectural scales. The
drawing area in the image reflects useable drawing area
of the title block. Inside the drawing area is a grid which
contains representations of 1”x1” squares.
A graphic component 100 ft. x 40 ft. drawn at a 1”=20’

It is crucial to create named views (command: VIEW) in XREF drawings (model space) for planning purposes. View
names must reflect the exact title of the drawing view, detail or section.
For example, an “air valve vault detail” view must be named, AIR VALVE VAULT DETAIL.
The AutoCAD® view manager, however, will not allow certain “special characters” in named views (such as
<>/\’”:;?*|,=`) but there is a workaround. Here are %% codes to use in place of these special characters:

Detail and section viewports must be numbered/lettered
via the Sheet Set Manager “Sheet Views” tab and
arranged in order to be read from left-to-right/top-to-

There are two types of sections: civil sections” and “detail
sections”. Civil sections relate to a plan view and are
typically dimensioned in an engineering format while
detail sections relate to a detail view and are dimensioned
in an architectural format.

SECTION 4: Drawing Standards
8/30/2024 City of Seattle BIM Standards 60
Every drawing must be in the world UCS with the 0,0 point defined by Survey in the Survey drawing. It is important to
utilize the standard coordinate system in order to allow information from different design disciplines to be displayed
together and be published to GIS. Each design drawing must be in model space (no design elements in paper
space). Have the base and other design drawings externally referenced during editing sessions, and when finished,
detach all XREFs.
North arrows must be oriented up, to the left or aligned within the area shown on the right.
Do not draw on layers 0 (zero) or Defpoints because they cannot be manipulated in an XREF.
Create the design in model space at 1 drawing unit = 1 ft.
The XREF type must always be “overlay” and the XREF path type must always be “relative path”.
Draft at Z = 0, design at Z = true elevation, on the correct horizontal and vertical datums.
Use standard COS layers, colors and linetypes; see layer standards database.
Abbreviations must be shown in accordance with Standard Plan No. 002.
Features must be drawn in accordance with Standard Plan No. 003.
Lettering must not be shown to identify features for which standard symbols are used, unless lettering is shown in
the standard symbols.
Linetype variables LTSCALE, PSLTSCALE, MSLTSCALE & CELTSCALE must always be set to 1.

Authoritative Drawings
It is important to designate drawings as authoritative, which means drawings that are used for data referencing and for
printing on sheets. Unless otherwise noted in the BIMxp, authoritative drawings must reside in this location:
\C-Civil\03-Design
Before creating authoritative XREF drawings, create a “Civil Plan Views” drawing (name of drawing file: [PTN]_X-
VIEW.dwg) and in model space add overlapping rectangles (for civil drawings put the rectangles on layer C-VIEW-
FRME) representing the limits of sheet viewports with match lines inside the overlap areas. These rectangles are scaled
by the planned viewport scale factor (for example, a 5”x2” rectangle in paper space equals 100’x40’ in model space at
1”=20’). Then create a named view for each rectangle. To do this, align the UCS (command: UCS) with the rectangle so
the Y direction is aligned along the narrow edge of the rectangle, orient the drawing space to align with the UCS
(command: PLAN; use “current” option) and create a named view (command: VIEW) that matches the limits of the box.
Repeat this for every rectangle. When finished, set the UCS back to World and copy and rename the drawing file as a
starting point to create every other authoritative plan XREF.
Work in Progress (WIP) Drawings
Working drawings may be created but must be saved separate from the authoritative drawings. Unless otherwise noted
in the BIMxp, working drawings must reside in this location:

Civil 3D® Object Naming Convention
It is important to add understandable names and descriptions to Civil 3D® objects. Some object types may be “data
referenced” into other drawings so it is important to use layer-control to ensure duplicate objects are not visible when
XREFs are overlaid in sheet drawings. Use this format:
[major layer discipline code]-[optional location]-[optional description]
Example for Pipe Network Names
Sanitary Sewer: SSWR-[optional location]-[optional description]
Storm: STRM-[optional location]-[optional description]
Combined Sewer: CSWR-[optional location]-[optional description]

External Referencing, or XREF’ing, is the standard procedure for concurrent engineering.
All XREFs must be set to OVERLAY and RELATIVE in sheet drawings and overlaid in the correct order so the base map
is on the bottom and the primary XREF is on the top. To avoid duplicate contours and alignments, freeze base map
and secondary XREF contours and alignments if those objects are shown in the primary XREF.
If information is not visible through a viewport, make model space of the viewport active, open Layer Manager, check
the “VP Freeze” column for frozen layers and thaw them if necessary. After doing this, if linework appears but
annotation is still invisible, set ANNOALLVISIBLE to 1 to see annotation not associated with the viewport scale.

Every design discipline must be a separate XREF drawing (drawings are more efficient if they only contain objects of a
single discipline). It is the standard to publish each discipline to ArcGIS separately (see Section 5.3) at milestones
specified in the BIMxp and keeping disciplines in separate drawings makes this process easier.
To create the highest-quality deliverables, these requirements must be followed:
1. The base map drawing must be XREF’d into design drawings as a basis for the design from this location:
\C-Civil\02-Survey\D-XREF (do not make copies of the base map).
2. Do not insert unnecessary items (things that won’t be printed, referenced, or published) into drawings.
3. Use the Autodesk Batch Save Utility (Standalone) to keep drawings clean by running cleanup scripts
(see: \W-Support\COS-defaultClean.lsp) to purge registered apps and run audits to fix errors. This will reduce
errors showing up in referenced drawings.
4. BIM is a cloud-only system thus you must not XREF drawings from local or network locations (otherwise a “related
data” folder will appear in the cloud). Before referencing a drawing, save it to the cloud first, and then create the
external reference.
5. Work in progress files must be saved in a WIP subfolder and not referenced into any standard drawings.
6. Sheet drawings (paper-space layouts) must reference the base map and design drawings into model-space, and
display all or a portion of the composite plan view with viewports in sheet drawings. Overlay the primary XREF last
so it is on top of all other XREFs (to put the primary XREF back on top, use the COPYBASE command with a base
point of 0,0,0 and erase the XREF; then use the PASTECLIP command with the insertion point 0,0,0).

centerline). Some Profiles may be created for presentation purposes (shown on sheets) while some may be created
for reference or design purposes but not shown on the sheets.
Profile Views (grids) in model space are for reference only and are used to align with the grids provided in layouts of

For multi-discipline projects, show nearby improvements
for context (such as showing water improvements on a
drainage plan) but freeze the annotation and change the
linework to color 145. To do this, overlay an XREF of the
secondary improvement, viewport freeze (VP Freeze)
secondary improvement layers that don’t need to be
shown (such as annotation) and change the viewport color
(VP Color) of the remaining secondary improvement
layers to color 145.
Proposed geo-referenced features and vertices of area
limits must be labeled in such a way as to easily locate in
the field (such as station/offset labels, Northing/Easting
labels or point labels referring to a table containing
station/offset data).

Add detail and section viewports to sheets via the Sheet Set Manager “Model Views” tab.
Details must be drawn to scale and are typically dimensioned in an architectural format.
Details must be separated into individual drawings (XREFs) by discipline. A detail drawing (XREF) must only
contain a set of detail views that share the same scale (unless a detail contains a blow-up).
There are two types of sections: civil sections” and “detail sections”. Civil sections relate to a plan view and are
typically dimensioned in an engineering format while detail sections relate to a detail view and are dimensioned in
an architectural format.
Details must be labeled with a title, scale centered under the title, reference numbers in a bubble callout to the
right of the title and a North arrow.
Sections must be labeled with a letter designation in this format: SECTION X-X # (sheet reference is shown to the
right of the title) and scale centered underneath.
Detail and section viewports must be numbered/lettered and arranged in order to be read from left-to-right/top-
to-bottom.
If a detail is provided in the City of Seattle Standard Plans, simply refer to it by number (e.g. STANDARD PLAN NO
###X); it is not required to be in the plan set unless it is modified.

All annotation must be set to “annotative”. Set the text size
for the drawing scale factor of 1 (plotted text height) in
model-space and allow AutoCAD® to size and display the
annotation based on the annotative scale set in the
drawing or viewport.
For example, if text with a height of 0.08 is placed in
model-space and the annotative scale is set to 1”=20’,
AutoCAD® will automatically size the text to 1.6 (viewports
with a scale of 1”=20’ will also display the text height as
1.6 which will then plot at 0.08 on a full-size plot).
Annotative Scale List
For scaling to work properly with XREFs, standard scale
name formats must be followed. Here are two standard
formats (please note that there is a space on both sides of
the equal sign):
Engineering scale format: 1” = x’
Architectural scale format: x/x” = 1’-0”

During the construction phase of projects, it may be necessary to develop revisions to the contract drawings. When
this occurs the Engineer of Record must work with the drafting team to formally prepare what is called a Design
Change document.
Definition of Terms
“Design Change Number For document control purposes, the Construction Management team assigns a number
to each Design Change package that is issued for a project. When preparing a Design
Change, this number will need to be requested from the Construction Engineer. The
Design Change document(s) must include, in large bold text in the lower left-hand
corner, a note with the Design Change Number. Additionally, on the left-hand side of
the title block, the table field must be filled out with the date, Sheet Revision Number,
Design Change Number, and associated initials.
“Sheet Revision Number For Engineering Services purposes, triangle blocks are used on Design Change
documents to identify the design revisions. The triangle blocks are labeled with an
associated Sheet Revision Number. This provides a correlation to the description of the
revision, and the associated Design Change Number. Sheet Revision Numbers must
start at one and increase by one for each subsequent revision to the respective sheet.

XREFs
The first step for project teams to take when the Construction Phase begins is to archive the XREF CAD files that were
used to generate the contract drawings. These XREF files need to be preserved in their original state as a city record,
and they will also be used by Construction Management and SPU Records to create As-builts. Design Changes must
not modify the original CAD XREF files, and modifications must be made to the duplicate file copies only.
Plot Sheets
Copy each of the sheet files that are associated with each design change (along with the Sheet Set Manager *.dst file)
and place in a sub-folder that is named with the Design Change number (e.g., DC-###).

Layers
Layers must be created for the triangle block with the Sheet Change Number, and for the revision cloud that will be
placed around the change itself. The 3-digit design change number must be appended to the end of the layer name,
as shown below.
Triangle layers: G-ANNO-TRIA-DSCH-###
Active change color: 240 | Previous (inactive) change color: 7
Revision cloud layers: C-ANNO-REVC-DSCH-###

Revision Triangles
Revision triangles contain a number, referred to as a “mark”, which is temporarily associated with a Design Change
Number written in the sheet revision block located on the left-hand side of the sheet.
The Sheet Revision Number triangle block must be inserted for each Design Change, as shown below.
Block name: _TAGTRIANGLE
Block scale: 1.2
Attribute text size: 0.18
Triangle blocks with “mark” numbers must be drawn in paper space of the plan sheet in which changes are being
made.
When multiple Design Changes are issued for the same sheet, the layers for the previous triangle blocks must be set
to color 7 to plot black.

Revision Clouds
Revision clouds are required for Design Changes and, before creating them, set REVCLOUDMINARCLENGTH to 0.25,
REVCLOUDMAXARCLENGTH to 0.25, and REVCLOUDARCVARIANCE to OFF.
When you run the REVCLOUD command, set the following parameters:
Arc length 0.25

change on the drawing), CHK’D (who checked the change), REV’D (who reviewed the change)
columns. The revision block may only contain a maximum of three most recent design changes.
Place Revision Clouds and Triangles
The current Design Change must be clouded and marked with a triangle on correct layers set to
color 240. All revision cloud layers from previous changes must be frozen, and the layers for
triangles from previous changes must be changed to color 7.

PDF Sheets for Signature and/or Archival
Publish sheets using the standard CTB to PDF format for
bid/conformed plan sets, and as-built plan sets.
Professional seals must be screened back 50% (color
254) so that electronic signatures are visible on them.
PDFs prepared for electronic signatures must have
layers disabled so entities cannot be hidden.
PDFs must be signed with electronic signatures, per
the State of Washington Board of Registration for
Professional Engineers and Land Surveyors. This means
that simply putting a likeness (image or vector) of your
signature on PDFs does not meet the standard. When
the plan set is ready to be e-signed, publish plans in
PDF format (with layers disabled) and provide a list of
required signatories’ names, e-mail addresses, and
phone numbers. Documents will be provided to City of
Seattle Adobe Sign administrator and routed for e-
signatures.
Final design and record drawing PDF files must be submitted to the City of Seattle Records Vault for archival.
8/30/2024 City of Seattle BIM Standards 128
It is possible to publish to PDF directly from Sheet Set
Manager for web. This uses the default layout of each

It is also possible to run the PUBLISH command and add
layouts to the list of drawings to batch plot.
To apply standard plot configurations to layouts (such as
11x17 PDFs for review, or 22x34 PDFs with layers disabled
for signatures), use page setups that are pre-configured
for different purposes.

Navisworks format to an Autodesk Docs® “shared” folder).
The objects or layers must have a material associated;
otherwise, geometry displays as the global material,
which is grey/white.
STEP 2: Launch Navisworks Manage®, create a new blank
file, and follow steps A and B on the right to append and
orient the NWC files stored on Autodesk Docs®.

A. Append Files (video):
Click Home tab Project panel Append
Browse to load NWC files stored in a “shared” folder
on Autodesk Docs®. This will append them to the
current Navisworks® file (click Viewpoint tab Render
Style panel Mode drop-down and select Full Render
to see the materials applied).
B. Adjust Model Orientation (if needed).
STEP 3: Publish NWD Model: Click the button and
select Publish (be sure to embed texture data).
Final design and as-built NWD models must be submitted to the City of Seattle Records Vault for archival.

Object Types
In Civil 3D®, collections of assets must be created in
separate drawings with the following object types:
Pipe Networks for gravity drainage and wastewater
(DWW) systems.
Feature Lines and Cogo points for pressure utility
systems (water, irrigation, sewer force mains, etc.).
Feature Lines and Cogo points for electrical and signal
site plans.
Feature Lines for ADA ramps and paving edges.
Cogo points for trees and signs.
Object Properties
Use the DWGPROPS command to add global project
information to objects (switch to “custom” tab and fill in
fields as defined in the BIMxp). Save the drawing.
Add additional data to objects in the “extended datatab
of the Properties palette (use CTRL+F to add sheet fields).
