In 2006, the MDOT / ACEC Design Technology Committee was formed.
To-date, several DTC Forums have been held throughout Michigan. Nearly 150 MDOT and Consultant designers attended each Forum. eProposal, PDF deliverables, GEOPAK, MicroStation and other
technology related issues.
In early 2007, the DTC presented MDOT / ACEC leadership with the DDEP concept.

DDEP Goal: Use current technology to……….
Produce deliverables to construction that will improve efficiency as well as reduce extras and overruns.
Improve the efficiency of developing design deliverables while reducing errors and omissions.

Quantities (63) – Minimize number of calculations, reduce errors, minimize manual handling of data.
Communication (50) – Improve access to information throughout development and delivery process.
![Page 8: Design deliverable enhancement project ( ddep ) - update](https://reader035.fdocuments.in/reader035/viewer/2022062305/56814a56550346895db77991/html5/thumbnails/8.jpg)

The following enhancements……… are not a final version. are subject to change. need input from stakeholders. need to be tested in the “real world” (Pilot Project). will be adjusted as needed based on input and
testing. will be finalized and presented in the future with
more in-depth supporting information.

Eliminate boilerplate information in plans and proposals. Include this information for each letting instead of for each project.
Provide as much digital information as possible at the time of bidding. Design cross sections Quantity spreadsheets Drawing files 3D digital terrain models Other

New sheet borders to be used for all sheets. Number sheets in PDF file. Formally integrate the use of MS Word and Excel in
the development of plan information in PDF format. Clarify information as much as possible.
![Page 14: Design deliverable enhancement project ( ddep ) - update](https://reader035.fdocuments.in/reader035/viewer/2022062305/56814a56550346895db77991/html5/thumbnails/14.jpg)
Sheet includes: Sheet index Utility contacts List of all standard plans and special details
Sheet is now developed using MS Word with the sheet border as a watermark.

Reduce the number of typical cross sections.
Provide design cross sections as a deliverable at each phase of a project for applicable projects.

MDOT will maintain a master note sheet in MS Word.
Designers will retrieve the master note sheet and delete notes that do not apply.
Project specific notes will be added to the end of the document.

Develop and maintain MS Excel Spreadsheets (Master and Working Files) that include all necessary layout, item and quantity information for the project.
Once the data has been reviewed…… Copy layout information to certain plan sheets. Create quantity sheets. Export *.csv file for SAPW / TrnsPort.
The goal is to create and review a master set of data then copy it to different locations. This will reduce errors due to manual manipulation.

Develop working files for each discipline or work group. Road (prime), Road (sub), Bridge (S01), Bridge (S02),
Traffic Signals, Electrical, Landscaping, etc. Each working file has a common format (tabs).
Input – Item and quantity listing broken down by Job No., Category No., Facility, DGN No., and Element ID. This information is either entered manually or automatically from GEOPAK.
Layout – Design variables, item usage and quantities required to construct certain elements. This information is either entered manually or automatically from GEOPAK.
Validation – Perform calculations to check quantities. Output – Export all item, quantity and break down data to Master
Project Spreadsheet.

Develop and maintain a Master Project Spreadsheet.
Collect and append output files from all disciplines and/or work groups.
Summary tabs use pivot tables to automatically sort and summarize all information by work type, pay item, facility, DGN No., Element ID, Job No., Category No., etc.
The total project quantity tab is automatically generated using a pivot table based on pay items.
Export tabs are used to copy all data as *.csv to SAPW /TrnsPort.
