Performance Criteria for Ready Mixed Concrete: Where Are We Today? (Part 2)-Performance Spec Concrete for a Super-Tall Building (Recorded Presentation)

Performance Spec Concrete for a Super-Tall Building (Recorded Presentation)

Video Transcription

Video Summary

The video transcript details the presentation by Eamon Connolly, Director of Engineering at James McHugh Construction, on the construction of the Vista Project in downtown Chicago—a notable addition to the skyline. This high-rise building features 103 stories and a diverse facility mix including a hotel, condos, and a parking garage, all set to be completed in April 2020. Connolly discusses the immense scale and complexity of the project, emphasizing the intricate concrete mixtures required for different structural elements. The discussion highlights the rigorous testing and collaboration necessary for developing high-modulus concrete mixes, which are critical due to local aggregate limitations. Strategies for managing mass concrete aspects, including temperature and strain challenges, were addressed using advanced testing and performance-based specifications. The project exemplifies innovative construction practices, teamwork, and meticulous planning to achieve success.
