Education Session #9: National Assessment of New Construction Market Pricing for Highway Bridges
The objective of this study was to analyze the initial construction costs of structural steel and concrete bridges that have been built across the United States in order to compare the in-place cost of these bridge types on national, regional, and state bases. The study focused solely on new and total replacements of structural steel and concrete bridges let by State Department of Transportations after 2011 and those that used a Design-Bid-Build delivery methodology.

Education Session #10: New AASHTO Guide Specifications for Exploiting Steel Bridge Redundancy
AASHTO has introduced two new Guide Specifications applicable to Fracture-Critical Members. In this presentation an overview of the fracture limit state will be introduced, followed by a summary of the research projects carried out lead by Prof. Robert J. Connor at Purdue University. The focus of the presentation will be on the Guide Specifications for Internal Redundancy of Mechanically Fastened Built-Up Steel Members, and the Guide Specifications for Analysis and Identification of Fracture Critical Members and System Redundant Members, particularly on their structure, applicability, and available resources for implementation.
Francisco Javier Bonachera Martin, PhD, PE
Pearl #3: BIM Workflows: From Analysis to Fabrication
This presentation will discuss an integrated workflow for project delivery in a BIM environment. This workflow encompasses the full range of engineering activities, including conception, FEM, plans production, detailing, fabrication, and construction documentation, and provides considerable efficiency in design compared to traditional processes.
David Loughery, CE
Pearl #4: Lightweight Modular Accelerated Bridge System For Managed Car Lanes
There is a widening infrastructure investment gap in the US. Aging infrastructure requires high maintenance dollars. On the other hand, severe congestion on important urban interstate corridors is leading to prohibitive economic costs. The US Highway system moves 65% of freight and 85% of passenger traffic. Research has revealed that the Bridge infrastructure is grossly underutilized due to high numbers of single occupancy car vehicles. This presentation proposes use of managed car lanes to relieve pressure on existing infrastructure by giving policy planners a tool to effectively augment and manage existing Bridge infrastructure network. The presentation defines a notional car load and presents an Accelerated Bridge System. This system combines Metal Grid Deck systems with Simple for Dead and Continuous for Live Load approach to create a rapidly scalable installation system for Highway Bridges for managed car lanes. The modular approach makes for easier construction, which is further enhanced by the light-weight superstructure.

Education Session #11: Complex Bridge Replacement on an Accelerated Schedule
The Edens Spur is a three miles expressway corridor connecting I-294 to I-94 in Northbrook, Illinois as part of the Illinois Tollway System. Ciorba Group led a team of engineering and environmental consultants to complete the design for the reconstruction and widening of the Edens Spur, which included the replacement of eleven mainline bridges and one crossover bridge. Many of these bridges have complex geometry and required design considerations to fit site constraints including high skews, super elevated bridges on curved alignments and deep foundations. The project goal was to modernize a vital part of the Tollway system originally built in the 1950s.
