Active Design Manual Revisions

Looking for the Design Manual in effect right now?

The most current WSDOT Design Manual is dated July 2014 and is available on the Design Manual Abstract Page:
http://www.wsdot.wa.gov/Publications/Manuals/M22-01.htm

The process for revising the Design Manual is given below, including the most current Review Points of Contact list.

This cycle of design policy revisions is focused on furthering Practical Design policy and guidance in accordance with Moving Washington Forward: Practical Solutions , and Results WSDOT – Our Strategic Plan .

The WSDOT Design Manual is typically published once per year in July. For 2015, publication will likely fall in November in order to shift to new practical design content and drop the use of the design matrix based approach.

Priority Design Topic / Affects Design Manual Chapter(s) Lead
Practical Design
Revise and replace multiple Design Manual chapters to shift WSDOT from standards based design to performance based practical design in 2015. Create new replacement content for Design Manual 1100 chapter series and Chapter 1230 Cross sections for Practical Design emphasis.

Each chapter is listed here and are found down this page.

Above listed chapter content informed by Reviews and Workshops:
>
 A preliminary review of "60%" draft content was conducted April 20 - May 15, 2015 in WSDOT SharePoint by region-selected points of contact. Edits and additional material were produced.
>July and August Workshops
A review workshop was conducted late July with input there continuing to guide the new content. This was followed by a two-day workshop to further refine the content and discuss need for guidance documents.


Chapter 300 Revised to conicide with new practical design approach This includes dropping terms and procedures known as design exception and evaluate upgrade among other changes. Deviations will still be a variance WSDOT uses and will remain in the chapter narrative. Added guidance on approvals for the Basis of Design.

The Details of Each Chapter Revision
more details will be added here

The tables below will show the chapters in the current revision. The column marked "Current Status" shows where a chapter is in the process.

  • When a chapter is ready for region/area review, it is posted in the first column.
  • All comments will be posted in the second column.
  • The third column is used to post the document with all comments merged and responded to.
  • The fourth column presents the chapter as an FYI posting to view the outcome.
  • After approvals, the chapter may be downloaded from the right-hand column called "Available for Use". This service allows designers to being using the new material before it is officially published

Chapter 710 Site Data for Structures
Revisions per the WSDOT Bridge and Structures office:

>Revisions are due to the series of Bridge Design Manual Design Memoranda (September 2014 through July 31, 2015), issued to implement WSDOT design practice for buried structures greater than 20-feet span along the length of the overcrossing alignment. 
> This is in keeping with the definition in 720.01 and the FHWA NBI responsibilities and WSDOT seismic design requirements.
> This affects the buried structures of the WSDOT fish passage program (precast reinforced concrete three sided structures, precast reinforced concrete box culverts and precast reinforced concrete split box culverts).
> Those buried structures scoped to be greater than 20-feet span will now be designed in the Bridge and Structures Office beginning with development of a preliminary plan layout at the onset of design.
> These Design Manual changes will help confirm the procedure in support of the intent of the BDM Design Memoranda.

WSDOT Design office edits:
> Applied current DM styles and layout - margins, body text, full section numbers, etc. Redated all pages. Documentation section updated.

Practical Design Guidance Documents
These documents provide further guidance related to the new Practical Design Manual chapters posted above. These were created in response to workshops participant ideas. The documents will be available online, separate from the Design Manual which will refer to them and provide you with links. The following documents are listed below:
> Determining project complexity
> Multiagency Advisory Teams
> Context indentification
> Performance based decisions
> Contributing factors analysis
> Writing effective need statements
> Alternative strategies and solutions
> Effects of different design elements on performance
> Documenting Community Engagement

Chapter 1230 Geometric Cross Sections
This chapter is vastly expanded with new roadway and street types added to stimulate creative outcomes for locational context. This is where much of the prior full and modified design level content was shifted, such as roadside sections for cuts and fill slopes. Roadway and street sections now provide ranges of values for design elements where prior content typically provided a single standard value. The 1100 series chapters as well as updated Chapter 300 instruct to begin designs with the lowest values provided - the "design up" approach.

The Design Manual Revision Process

Design Manual chapters currently planned for revision are listed in the tables above.

  • When a draft chapter is ready for WSDOT Region and Area review and comment, a "Policy Review Draft" is posted in its respective table and designated points of contact are notified.
  • The points of contact then download the chapter file and distribute to people in their region/area.
  • Tables show the comment review period (usually 4 weeks).
  • Points of contact collect comments and send back to HQ Design Office. Those comment files are posted in the tables as they are received.
  • After evaluating all comments, the Design Office posts a file showing the final draft, with all comments and the HQ Design Office's response to them. Not all comments are used, but all are considered.

When a chapter has "final approval," it will be available for use prior to publication. See the link in the right-hand column of each table as chapters are approved.

Region "Points of Contact" (POCs)
WSDOT regions have identified specific people to act as POCs to coordinate a unified region response to draft policy changes.

  • POCs coordinate with people in their region to review/comment on draft policy.
  • POCs send their region's comments back to HQ in one document.

View WSDOT Region and Area points of contact list (updated 9/4/15)
