A Scale of Two Cities – Dan Goldsworth and Mark Stinocher, Project Bluejay; Jordan Stokes and Nick Aldrich, Krause Gateway Center
This presentation will highlight the use of concrete in two of Ryan Companies’ most unique projects, Krause Gateway Center in Des Moines and Project Bluejay in Bondurant. Each project was complex in its own way—Krause required extensive collaboration with the design team to achieve high-end finishes, while Project Bluejay’s scale and accelerated schedule presented our team with many new challenges. Our team will talk about our approach to these two very different projects including innovations, successes, and lessons learned.

Wet-Weather Strategies for Handling Concrete Placements Exposed To Rain – Ron Kozikowski, North Starr Concrete Consulting
Whether you are an owner, contractor, or engineer, there is a good chance you’ve had to deal with a concrete placement exposed to rain. If a rain event occurs during a placement, concrete can still be placed safely if the rain event is handled properly. This presentation will discuss how different stages of placing and finishing are affected by rain and what preventative actions/options are available to contractors at each stage. It will cover the benefits of a wet-weather plan and what one should include. Repair options will also be covered for those placements that have been negatively affected by rain.

The New ACI 301-20: Specifications for Concrete Construction – Michelle Wilson, Director of Concrete Knowledge, Portland Cement Association (PCA)
ACI Committee 301 recently completed a comprehensive revision to the content of ACI 301, “Specifications for Concrete Construction.” This update expanded the scope of ACI 301 and revised many of the requirements that have been in previous editions for many years. The goal of this session is to show how the design and construction team should use ACI 301 when it is referenced in project specifications. Understanding the relationship between ACI codes and specifications is emphasized. Topics include modifications to many of the default requirements within the specification and an introduction to new topics.
