Trinity Parkway Project History

1967 - Regional Transportation Study indentified “River Freeway”1986 - “Mobility 2000” plan recommended Trinity Parkway1998 - NTTA assigned development of Trinity Parkway 2004 - USDOT selected Trinity Parkway as a “Priority” Project2005 - City of Dallas & NTTA recommended Parkway alignment2009 - Completed 30% Design and submitted Section 408 to USACE

Benefits of Trinity Parkway

• Mobility Benefits– Unlocks Downtown congestion nightmare – Allows reconstruction of Existing Canyon/Mixmaster – Reduces congestion cost by $66 million / year– Saves 4.2 million vehicle hours / year

• Social & Environmental Benefits– Supports the City of Dallas’ Balanced Vision Plan (Trinity Master Plan)– Reduces emissions by 84 tons / year (10% reduction)

Collaboration Challenges 

• Aggressive Schedule – Four Month Design Schedule– 30 % Design Submittal to USACE

• Technical Challenges– Integrating a Project Team by means of Virtual Office – Connecting and supporting Project Team

• Human Element– User reluctance to work in a collaborative environment– Failure to see “Team vision” due to “cubicle mentality”

KEYS TO SUCCESSFUL COLLABORATION

• Project Management • Virtual Office • Design Applications• Work Flow

Project Management 

• Project Managers & Task Leaders– Understanding of “Collaborative Environment”– Mentoring Teaming Partners

• Project Documentation– Project Guide describing Team members’ specific roles– CAD Guide addressing design and drawing workflow

• Project Communication– Establish communication at every level of Management– Communicate design changes effectively

Mentoring Program • Hayden Consultants, Inc. selected as Protégé Partner

– Mentoring of local DBE firms encourage by NTTA – Given a significant Management & Design role

Deputy Project Manager Roadway & Storm Water Pollution Design

• Mentoring Program – Project Management Training– Design Software Training

ProjectWise MicroStation/GEOPAK

Results of Successful Mentoring & Training

“This is a software tool (ProjectWise) that our firm would not have had the opportunity to use had it not been for the relationship with HDR. The HDR staff not only trained our engineers in the use of ProjectWise, but they provided detailed training in aspects of MicroStation/GEOPAK that we had not been exposed to before.”

KEYS TO SUCCESSFUL COLLABORATION

• Project Management • Virtual Office • Design Application• Work Flow

Work Flow

• Project Folder & File Structure– Structure tailored for your Project – Securities which allow access control– Standard Naming Conventions

• Drawing Organization– Base and/or Model Files – Sheet Files– Use of Reference Files– Image Files

Enhancing Work Flow Speed

• Open Files Read Only – One Way download (no need to check back in) – Eliminates the need to refresh Design Team copies– Audit Trail reflects copied out status

• Cad File Maintenance– Eliminate unnecessary Drawing Data– Remove unused models – Compress files thereby reducing file size

Enhancing Work Flow Speed • Reference Files

– Detach unwanted References/Images– Remove all missing References/images– Clip Reference/Images files to fit project limits– Lockdown all Exist and Survey References/Images– Place Raster Images on Local Network not in PW

Models in Your Work Flow

• Models– Not to be confused with AutoCAD Paper/Model Space – Allows the user to set the following

Annotation Scale for Text, Dimensions, and Cells Linestyle Scale for custom linestyles Level Symbology for Reference files Sequencing of Reference attachments

– Simplifies attachment of Reference files to Sheet files– Controls Level Display at one source – Can create multiple models in a Reference File
