Demystifying Utility Coordination: Understanding The Basics, Josshe I. Palm

Purdue Road School

This session will explain utility coordination to non-utility coordinators. It will help educate others about the role and responsibilities of a utility coordinator, an OSA, easy UC and design mistakes to avoid, scope and design considerations, items commonly overlooked, when to coordinate SUE, and how to work with your UC to request a letting adjustment. We will also highlight UC submittals and allow time for questions about the UC’s role in a project’s success.

Environmental Assessments On A Local Project, Robert Winebrinner, Trevor Wieseke, Summer R. Elmore, Alison Krupski, Mike Maurovich

Purdue Road School

This presentation will go through the environmental process of a recent $125M local project within Noblesville. What are the major differences between the National Environmental Policy Act (NEPA) and State Environmental Policy Act (SEPA) process as it relates to an environmental assessment (EA)? What is required, what is not required, and what is optional? How long does the process take? Join us as we walk through this exciting process and experience.

Railway Bridges Up-To-Date, Stephen Dick

Purdue Road School

Railroad bridges are not foremost on people’s minds, but they are still a critical item in our nation’s infrastructure. The railroads have a major investment in their bridges, and with many beyond 100 years old, maintenance and replacement of them is still a major cost item. This presentation describes the current state of railroad bridges, discusses older and new bridges, and addresses the current regulatory environment.

Waterproofing Membrane For Concrete Boxes And Culverts, Keith Alan Lytton P.E., Jeremy Hunter P.E.

Purdue Road School

In 2019 a new INDOT Specification went into effect for waterproofing on concrete pipes and three- and four-sided boxes. The new specification decreased the leakage at these structures joints from 95% to less than 5%. This presentation will provide the background on why the change was needed and the solution, complete with construction examples and results.

Bim For Bridges And Structures Pooled Fund Initiative, Julie Rivera, Connor Christian

Purdue Road School

The BIM for Bridges and Structures initiative, also known as TPF-5(372), is a transportation pooled fund project that is a collaborative effort of 20 states, FHWA, and the AASHTO Committee on Bridges and Structures. The pooled fund objective is to develop an open, national standard for exchanging information necessary for the design, fabrication, and construction of bridges and structures in the United States. The presentation will provide an overview of the project and explain ways in which stakeholders can get involved.

A Look At Indot's Overhead Sign Structures, David Boruff

Purdue Road School

This presentation highlights results of sign sheeting field review and associated changes in policy and standards, as well as how we’re implementing the findings from our overhead sign structure inspection program through the first statewide overhead sign structure repair and replacement contract.

Load Rating Of Bridges Without Plans, Rafael Armendariz, Mark Bowman

Purdue Road School

The presentation will address the challenges of load rating bridges without plans and how a four-step procedure can be used to guide the engineer in determining bridge ratings for poorly documented bridges. The procedure is illustrated through the assessment of an earth-en-filled reinforced concrete arch bridge with no available bridge information.

When To Use Midwest Guardrail System (Mgs) W-Beam Guardrail, Katherine Smutzer

Purdue Road School

In this session we will discuss when MGS w-beam guardrail should be placed on state and local projects and review pertinent INDOT Design Memos released over the past year.

Wildcat Bridge - I-65 Artesion Well/Geotechnical/Structural, Anne Rearick, Jeremy Hunter, Silas Nichols, Mir Zaheer

Purdue Road School

In this session we will discuss the emergency design and repair of the I-65 bridge over Wildcat Creek in Tippecanoe County during the summer of 2015 that closed I-65 northbound.

Storm Damage - Floating Culverts, Dale Sedler, Mark Bailey

Purdue Road School

A review of buoyancy issues culverts experience due to blockage. Includes discussion of blockage due to floating debris and issues with multiple culverts. Provides information on characteristics that help to determine if a culvert has "floated."

Post-Failure Capacity Of Built-Up Steel Members, Matthew H. Hebdon

Purdue Road School

Mechanically fastened built-up steel members have long been known to possess internal member redundancy and, as a result, multiple load paths which can be exploited to increase their functional life. Internal redundancy provides the ability to resist total member failure in the event of a fracture of an individual component. However, there is little experimental data in the literature regarding post-fracture capacity in terms of strength and subsequent fatigue life. The experimental study currently underway will provide needed information on parameters that affect the ability of built- up members to arrest a fracture as well as the available remaining fatigue …

Post-Fracture Capacity Of Railroad Flat Car Bridges, Teresa L. Washeleski

Purdue Road School

Railroad flatcars (RRFCs) are a convenient option to replace existing deteriorating bridge structures on low-volume roads. They are typically used as the bridge superstructure by placing two or more flatcars side-by-side to achieve the desired bridge width. Utilizing RRFCs as a bridge allows for rapid construction and greater cost savings compared to traditional practices. These benefits make them an attractive solution for rural communities in Indiana, as well as other states.

Uncertainty remains about the response under higher loads than could be easily achieved in the field and the level of redundancy of railroad flatcar bridges. Using RRFCs as bridges …

2014 Road School, Kevin M. Hetrick

Purdue Road School

At the 2014 Road School, this presentation focused on the proposed sliding of the Milton-Madison Bridge, a 15000 ton truss superstructure intended to move laterally 55 feet from a temporary location onto permanent piers. The project was a joint procurement between INDOT and KYTC, with a Design/Build team consisting of Walsh Construction, Buckland and Taylor, and Burgess and Niple performing the slide. The presentation was in early March, with the slide scheduled for later in the month. The slide will be the largest of its kind.

Best Practices For Bridge Deck Overlays, Tommy E. Nantung, Robert J. Frosch

Purdue Road School

This presentation discusses recent research regarding alternative bridge deck overlay methods and best practices associated with their use.
