ITC BIM for Infra DEA Webcast Series LP

Webcast Series: Transforming Road Design Workflows with David Evans & Associates

David Evans & Associates, Inc. (DEA) is a recognized leader in the design and management of complex transportation, land development, water resources, and energy projects nationwide. In this series of presentations, Dan Iliyn, Civil Engineer in DEA’s Roads & Highways group, will provide a look into how they implemented Autodesk BIM solutions for Infrastructure in the design of a $35 million dollar transportation project for Oregon’s Washington County: the extension of 124th Avenue through unincorporated county land between the cities of Tualatin and Sherwood.


Part 1 of 3 – The 124th Avenue Extension Project: The Preliminary Design Process

The 124th Avenue Extension is a $35 million project that includes over five miles of new and improved rural and urban roadways, extensive drainage features, and a five-lane bridge spanning a railroad. This project will impact many adjacent businesses and homeowners. As a result, it has attracted a lot of public interest.

In this first of three webcasts, Dan Iliyn will give us a brief introduction to David Evans & Associates (DEA). He will provide an overview of the 124th Avenue Extension project, describing some of the preliminary design methods and processes DEA used for open house presentations prior to their use of Autodesk’s Infrastructure solutions including Autodesk InfraWorks. Dan will delve into some of the challenges that contributed to DEA’s move to BIM and the use of InfraWorks in this project. He’ll present what was done and how InfraWorks 360 was used.

David Evans and Associates, Inc.

Dan Iliyn has quickly become one of David Evans & Associate’s most trusted and creative young civil designers in the transportation field. His experiences have been focused primarily on roadway and transportation projects with an additional focus on multi-use trail & LRT design. He is one the leaders at DEA when it comes to the 3D design and realistic visualization renderings of projects that provide interested parties and stakeholders a unique perspective and help bring clarity to the decision making process. His approach blends technical skill with collaborative, solutions-oriented concept designs to address complicated transportation issues and find agreement amongst divergent stakeholders through the selection of alternatives that provide the greatest benefit and value.

Part 2 of 3 – The 124th Avenue Extension Project: Challenges to Overcome

With part of the 124th Avenue Extension going through the middle of an existing rock quarry, the roadway will have significant elevation changes requiring numerous rock cuts, walls, and re-grading of adjacent property driveways. In this second webcast in the series, Dan Iliyn shares DEA’s experience moving to BIM as they attempt to overcome some of these project design challenges.

Dan will focus on the project roadblocks they ran into and how these were resolved through Autodesk solutions and InfraWorks. He will touch on starting the project with Bentley’s MicroStation/InRoads and translating that into InfraWorks. Dan will then setup the 3rd and final webcast in the series by highlight some of the benefits of this process to enable smoother preliminary design, visualization to design workflows.


Part 3 of 3 – The 124th Avenue Extension Project: Future Decisions

In this 3rd and final webcast of the series, Dan Iliyn reviews the current state of the 124th Avenue Extension project. He’ll dive into the process flows between InfraWorks and Civil 3D. He will also delve into what’s in store for DEA as they continue to enhance their implementation of BIM workflows in their projects. Dan will briefly discuss the new tools and services that DEA are considering and talk about how they could benefit the 124th Avenue project. He’ll discuss how he sees InfraWorks 360 being integrated more broadly into their project workflows, beyond visualizations for planning purposes and proposals.
