June 18, 2018 - 8:00am to 5:00pm

 

Bala Sivakumar and Johann Aakre will lead this full-day workshop on Accelerated Bridge Construction.  The workshop will introduce engineers to the basics of ABC, introduced in a way that focuses on the key differences between ABC and conventional bridge design. The aim is to allow engineers familiar with traditional bridge design learn the key concepts of ABC and advance the application of ABC to bridges.

 

Topics will include:

  • Introduction to ABC
  • ABC Project Selection and Implementation
  • SHRP2 ABC Toolkit and ABC Guideline drawings
  • Prefabricated Bridge Elements & Systems

-Introduction
-Precast Decks
-Modular Superstructure Systems
-Modular Substructure Systems
-Erection methods
-Connections & Connection Materials
-Tolerances
-Overlay Systems
-Case Study

  • Slide-In Bridge Construction with Case Study
  • Self-Propelled Modular Transporters (SPMT)
  • ABC Contracting, Cost, Schedule
  • ABC Resources
  • Q & A

About the Presenters

Bala Sivakumar, PE,

Vice President and HNTB Fellow, Director of Special Bridge Projects

With 35 years of experience, Bala’s expertise includes accelerated bridge construction (ABC) of complex bridges, weight-in-motion (WIM) studies, live-load and finite element modeling, fatigue and fractures investigations, and seismic analysis and retrofit. Recognized nationally as an expert in load and resistance factor design (LRFD) and evaluation of bridges, he was the primary author of the new AASHTO Manual for Bridge Evaluation. He co-authored the Transportation Research Board’s Strategic Highway Research Program II (SHRP 2) R04, titled Innovative Bridge Designs for Rapid Renewal, which includes national ABC standards, guidelines for design drawings, guidelines for erection systems, and LRFD design and construction specifications. He was also the primary developer and author of the SHRP2 ABC Toolkit published recently to promote ABC implementation nationally, which has been recently expanded to include lateral slide concepts. He leads HNTB’s national ABC practice and is involved in ABC projects in several states.

 

Johann Aakre, PE, SE

Bridge Section Manager

In his 14 years with HNTB, Johann has contributed to the design of several different bridge projects.  Johann’s bridge design experience includes preliminary through final plan design of various structure types, including highway, pedestrian, rail, design-build, and signature/complex bridges.  He is the Great Lakes division representative on HNTB’s ABC committee and has recent experience on ABC projects in Minnesota, Michigan, and West Virginia and for the Union Pacific Railroad.  He serves on the SEAOI Board of Directors.
