President's Memo

It’s been a great start to 2019. Our annual report to ACI national was due February 1st, and we recently found out that our chapter was recognized as an “Excellent Chapter” for 2018. This status is the highest level of achievement for a local chapter, and only 23 ACI Chapters from around the world are receiving this recognition.  This could not have been achieved if it weren’t for our board and participating members. Thank you!

In other news, please save the date for our Annual Dinner at the Mid-America Club located on the 80th floor of the AON Center. The big day is Saturday May 11, 2019. I hope you can join us to network, celebrate another great year, and congratulate our Henry Crown Award Winner. The AON Center is that white rectangular skyscraper that’s about 1200 ft high on Randolph St close to the lake. See Figure 1 below.  Watch for the formal invitation to arrive in your email inbox in a couple of weeks.

There are only 2 more dinner meetings left in the season, so I hope to see you at next one and at the Annual Dinner.

February Meeting Summary

On February 20, 2019, Mr. Sean Guzik, Acting Quality Assurance Manager, provided an update on the Chicago Department of Transportation (CDOT). Mr. Guzik started his current position in March 2018. One of the policy updates mentioned is that starting March 2019, CDOT will require ACI's Concrete Strength Testing Technician certification for all technicians that perform strength testing and the QC managers that sign-off on results on CDOT projects. Mr. Guzik highlighted CDOT's involvement in the Construction And Materials Asset Management (CAM-AM) group. CAM-AM brings local transportation agencies together to evaluate innovative ideas to improve infrastructure.  

CDOT has a variety of construction projects planned for 2019 and beyond including the North Lake Shore Drive reconstruction, Damen/Lake CTA green line station, 43rd Street pedestrian bridge, Harrison Street viaduct over Union Station, Wells Wentworth Connector Section 3, and the Division Street bridges over the Chicago River and North Branch Canal. There will also be a number of Streetscape projects in 2019 throughout the city.

Bowling Ball Competition

On Saturday February 9th, ACI IL hosted its second annual student concrete competition at the Elmhurst training facility.

The competition was based on the Fiber-Reinforced Bowling Ball competition that is held at the National Convention every few years. Teams were challenged to create a round ball approximately 8" in diameter, with a maximum weight of just over 12 lbs. Three total student teams participated - UIC, SIUE, and Valparaiso University. Competitors first hurled their balls at bowling pins and then loaded them to a full inch of deflection. The winner was the team best able to balance the competing requirements while still holding the most load. Team SIUE won the competition, taking home the $750 prize.

Special thank you to our sponsors for this student event: GCP Applied Technologies and Sika.

In addition to the students, members of the ACI community were welcomed to compete for the illustrious ACI IL Student Competition Non-Student Traveling Trophy, 10 lbs of beautifully-cast concrete crown. This year, the competition was intense, with teams from Elmhurst Chicago Stone, Ozinga Chicago, and Flood Testing Labs participating. The excitement was tangible as Peter Schroder of Ozinga came within 1 pin of taking the lead. However, Mark Korduck of Flood Testing Labs was able to maintain his tenuous grip on the illustrious trophy for another year. The awards were announced at the February 20 dinner meeting at Erie Cafe.

The chapter plans to host its next competition in February of 2020, just months before hosting the National Competition in Rosemont. Rules will be posted to the ACI IL website. Start working on your mix designs now in order to steal the trophy away from Mark.
