This is the home of the Central Pennsylvania Chapter of the Construction Specifications Institute. Please come on in and look around. We'd love to see you at a meeting or other Chapter event!

The Construction Specifications Institute (CSI) is a nation-wide nonprofit technical organization dedicated to the advancement of construction technology through communication, education, research, and service. Founded in 1948, CSI provides a forum for architects, engineers, specification writers, contractors, suppliers, and others in the industry.

A Winning Bridge Design

Hunter Ruthrauff of T.Y. Lin International, San Diego, CA, will present his 2021 AISC Forge Prize-winning design for a 3D-printed steel pedestrian bridge, extending approximately 1,000 feet east-west across the Florida Canyon in San Diego’s Balboa Park. Meeting format will be a presentation on Zoom followed by discussion between Hunter and attendees on the aesthetic and technical concepts of the bridge design.

Ruthrauff’s design draws on Spanish-inspired architecture in the adjacent Prado, local flora, and the nearby Cabrillo Bridge. The bridge’s organic form reflects the network of trails in Florida Canyon. The bridge’s deck offers uninterrupted views and some unconventional public space consisting of large hammocks over four apertures that look down onto the canyon. The project would take advantage of the unconventional shapes possible with 3D-printed structural steel.

Learning Objectives for Program Participants:

1.  Examine the contextual influences that inspired the bridge’s design and details.
2.  Explore the envisioned pedestrian experience, including safety features..
3.  Discuss the fabrication and erection process contemplated for the bridge’s structure, and how they will contribute to an efficient construction methodology and a structurally sound outcome.
4.  Understand the reduced impact on environmental resources resulting from the bridge design.

The Forge Prize competition (www.forgeprize.com) was established in 2018 by the American Institute of Steel Construction (AISC) to recognize visionary emerging architects for designs that embrace steel as a primary structural component and capitalize on steel’s ability to increase a project’s speed.

Presenter Background:  Hunter Ruthrauff is a senior design associate within T.Y. Lin International’s Architecture and Visualization Group (AVG). He grew up in LA county and received his Bachelor of Architecture from Cal Poly Pomona and a Master of Science in Architecture Design Computation from the University of Washington, Seattle. At T.Y. Lin International, he designs some of the firm’s most high profile vehicular, pedestrian, and rail bridges. He is also a founding member of the company’s innovation department and the head of the Digi-Fab Lab that experiments with 3D printing and CNC routing. He heavily leverages parametric tools in his design process as a way of iterating and exploring architectural form as well as streamlining documentation. He is the co-founder of M-Form and the inventor of the company’s robotic mold technology that specializes in the mass customization of curved architectural precast concrete panels.
