Title: 3D/4D Modeling Applications for Highway Design and Construction

Presenters:	Kevin Gilson, Director of Design Visualization, Parsons Brinckerhoff
	Brady Nadell, P.E., Project Manager, Parsons Brinckerhoff

Innovative digital tools and technologies are changing how highway engineers plan and deliver their projects. The use of 3D/4D modeling, model-based design methods, and virtual design and construction (VDC) processes fosters collaboration among project team members, identifies potential conflicts early in the design phase, and reduces project delays. This session will summarize how these tools and processes are being applied on large highway projects, and discuss direct benefits achieved. The session will present case study examples of several large projects including the San Francisco - Oakland Bay Bridge and Doyle Drive - the southern approach to the Golden Gate Bridge; and outline how BIM/VDC tools were implemented and some of the problems faced in adoption of the technologies. Attendees will leave with a better understanding of where these technologies can add value to their projects and some of the challenges associated with implementation.

Title: Ensuring Airport Approach Safety Using the Latest Surveying and Surface Modeling Technologies
Presenter: Greg Miller, Texas Department of Transportation, Aviation Division

We all know how important our Airports are to the day to day operations of this country. In order to ensure this safety, large areas are mapped with very accurate locations along the flight paths into airports. These areas are surveyed using multiple methods to obtain real world locations for buildings, towers, large trees, utility lines and all other features that could cause a conflict with an incoming aircraft. This information can then be used by the traffic controllers and pilots to guarantee safe flight paths. This is especially critical if planes need to make more unorthodox landings due to problems. Having the location of obstructions immediately available enables emergency decisions to be performed with a far greater safety factor for the incoming aircraft. This session will cover the methods used to collect, analyze, and distribute this information.

Title: Decreased Costs, Increased Quality - Paving the Way with Modern Technology

Presenters:	Karen M. Weiss, P.E., Autodesk, Inc.
	Steve Stanfill, P.E., P.L.S., Autodesk, Inc.

With the increased investment in our nation's transportation infrastructure, including repairing and upgrading deteriorating roads and bridges, and building out new infrastructure to support growth, transportation professionals in both the public and private sector are looking to streamline workflows to optimize the use of available funds. Technology plays a key role in producing a high quality product, on time and within budget.

This session will focus on processes that are based on Building Information Modeling, or BIM, which relies on the use of coordinated and consistent data. To do this, real world cases will be examined, showcasing how modern technology that supports a BIM process helped to save time and cut costs. Scenarios include integrating geospatial data in the preliminary design phase of a project to assist in the determination of agricultural and environmental impacts during corridor selection; dealing with unexpected problems in the final stages of detailed design without affecting the project schedule; and finally, how to enhance QA after final design is complete in order to uncover problems before construction began. Session attendees will gain an understanding of how the same principles and methods can be applied to include those projects being accelerated due to stimulus money spending.
