How Precast Builds: Parking Structures that Deliver the Precast Concrete Promise

This webinar will highlight two award winning precast concrete parking structure project case studies, one in the Midwest and one on the West Coast. The learning content will focus on how the precast concrete components were able to be designed to meet the building's program requirements. They will also describe how the use of precast concrete for the project facilitated seamless integration with adjacent natural features and adjoining structural and architectural systems.

  1. Understand precast concrete parking structures, including their standard components and custom design opportunities.
  2. Understand best practices in designing parking structures with precast concrete systems for aesthetics, resilience and safety.
  3. Use a mixed-use structure case study that includes a precast concrete parking structure to (Ft. Wayne, IN) to help participants understand the core value of precast concrete parking structures for owners and design teams.
  4. On the basis of a higher education case study presentation (Sacramento, CA), understand how precast concrete parking structures can be designed to connect with nature and provide exceptional resilience.

Corey Greika P.E., Vice President & Sales Manager, Coreslab Structures (Indianapolis).
  • 21 years in the precast/ prestressed concrete industry
  • Held positions of QC technician, plant engineer, design engineer, engineering manager, sales engineer and sales manager
  • Graduated from the Georgia Institute of Technology with a Bachelors of Civil Engineering (Structural) and a Bachelors of Science in Architecture
  • Have worked with precast in the Midwest and Southeast markets.
  • Member of the PCI Marketing Council.

Thomas Ketron is a strategic marketing and communications professional with over 20 years' experience ranging from the telecommunications and software industry to construction and prefabricated building systems industry. He is a founding member of the Precast Concrete Institute’s Sustainability Council and serves on the Institute's Marketing Council. A LEED accredited professional, he looks for ways to communicate value and help bring meaningful and transformative technologies into constructive products and systems that can help make the world a better place.

At the core of his being, Jason Silva is best described as an inventor. As the Design Principal at Dreyfuss + Blackford, he continues to push the boundaries of traditional architecture. Fascinated by both phenomenology and the mechanics of materials, Jason’s work is predominantly performance driven, advanced by technologies in design and fabrication. Breaking down complacent norms, he continues to ask “what can be done to make ______ better?”

After receiving his professional degree in Architecture from Ball State University, Jim Hoch began his career in Indianapolis assisting in design and construction documentation of office and commercial architecture. Upon moving back to his roots in Fort Wayne, Jim continued with design and project management of health care and commercial offices, as well as the telecommunications industry, throughout northeastern Indiana. In 1994, Hoch Associates was incorporated with a concentration in these same areas of architecture and expanded its presence in Indiana with a second studio in Indianapolis in 1997. The firm’s accomplishments have garnished several award winning projects most recently the Skyline Plaza Garage development in downtown Fort Wayne, which received the Engineering News Record Midwest’s Best Government Project, and the Promenade Park River Development currently being constructed.

PCI Offers FREE Bridge Geometry Manual and Training Webinars

A “Bridge Geometry Manual” has been developed as a resource for bridge engineers and CAD technicians. In nine chapters, the manual presents the basics of roadway geometry and many of the calculations required to define the geometry and associated dimensions of bridges. A simple log-in to the PCI website is all that is needed to download these free resources. This manual and course is not linked to any software tool. Four instructor-led training (ILT) courses are being developed to facilitate the use of the Bridge Geometry Manual.

This document was created by a team of subject matter experts (SMEs) directed by John Corven,P.E. of Corven Engineering Inc., the Lead SME. The team was engaged in each stage of development. At the final draft, the PCI Committee on Bridges was balloted. Lastly, the PCI Technical Activities Council was balloted. All comments resulting from these reviews were reconciled to the satisfaction of the reviewers.

Mr. Corven has now developed four companion courses based on the approved document and PCI is excited to share this information. The target audience for the Bridge Geometry Manual and ILT courses is bridge engineers with two or less years of experience and CAD technicians who have not had previous training in roadway and bridge geometry. There is no cost to enroll in and complete any of these courses or to download the new manual.

Fundamentals of Roadway Geometry (T505)

April 16, 2019 at 2:00 PM Eastern

Fundamental to establishing bridge geometry and the resulting geometry and dimensions of bridges is the ability to work with roadway geometry provided by highway designers.  Terminology used in roadway geometry is discussed.  The three primary aspects of roadway geometry (horizontal alignment, vertical profile, and cross section super elevations) are presented in this course.  Stationing along horizontal alignments is also defined.  Mathematical formulae and graphical representations are presented to define these three primary aspects, along with worked example problems.



Working with Horizontal Alignments (T510)

April 30, 2019 at 2:00 PM Eastern time

Locating points along or offset from a horizontal alignment is necessary to defining bridge geometry.  This course presents a vector-based approach to locating the North and East coordinates of point defined by a horizontal alignment.  The vector-based approach was taken as it closely follows the way CAD software is used.  Vector solutions are presented for 1) Locating points on tangent runs and circular curves, 2) Locating points offset from tangent runs and circular curves, and 3) Project points onto a tangent run or circular curve.



Geometry of Straight Bridges (T515)

May 14, 2019 at 2:00 PM Eastern time

The third course begins by introducing terminology common to bridges elements.  The material presented in the first two courses is then used to define the geometry of straight bridges.  Concepts of skew crossings and the impact on bridge geometry are presented.  Haunches that are cast over girders along with the bridge deck are defined.  Factors effecting haunch thickness are defined using mathematical equations, which are demonstrated through examples.  Substructure geometry in the form of top of bearing seat elevations is presented.  Example problems are used to reinforce the information presented.



Curved Bridge Geometry (T520)

May 28, 2019 at 2:00 PM Eastern time

This course advances the approach to bridge geometry developed for straight bridges to curved bridges.  The geometry of curved bridges using both straight, chorded girders and curved girders is presented.  The geometry of two curved bridge types (precast segmental box girders and curved u-girders) is introduced and an approach to computing their geometry is outlined.
