President's Report

It’s hard to believe that we are a quarter of the way through 2019 already. I recently returned from the ACI convention in Quebec City, which was very interesting. I have never seen so much snow on the ground, up to 10 feet still lingering from the winter, and then land in Atlanta where it seemed like we had 10 feet of pollen on the ground!!

The chapter is still hard at work preparing for the upcoming Convention here in Atlanta. 2021 will be here before we know it and we will need volunteers to help with many aspects of the convention, so please reach out to any of the Board members if you're interested in helping.

We have some very exciting topics coming up at our Luncheons, including everyone’s favorite topic – cracking, this month, which Gregory Zeisler from ACI will be joining us to present. I am looking forward to this presentation and hope many of you will join us as we all deal with this issue every day.

I think it is also important to stress safety this time of year. The days are longer, and the afternoons are full of everyone rushing around trying to get kids to sporting events, tutors, and many other activities, at least that is what my wife deals with regularly. So, lets all remember to slow down and pay close attention to our tasks, and leave a little early if needed to make sure we arrive safely.

Justin Lazenby
Georgia Chapter ACI, President

New News Column: ACI Spring Convention in Quebec City

“ACI’s Newest Fellow”

The GA Chapter was well represented at the ACI International Spring Convention in Quebec City, CA. In addition to our normal contingent of certification and technical committee members, we had two additional groups in attendance. Several of us were on a fact finding mission to garner information for ACI’s Fall Convention 2021 in ATLANTA!  A lot goes into to planning an ACI Convention and we have a dedicated group of GA Chapter Members, led by 2021 Convention Co-Chairs; Angela San Martin and Wayne Wilson, well on their way to making 2021 a success. In addition, we had the privilege of seeing one of our own, Martin Cuadra, honored as our Chapter’s newest ACI Fellow. Martin, with his family in attendance, received this special honor at the opening session on Sunday night.  The following is a reprint from the March Issue of Concrete International which summarizes what it means to be an ACI Fellow and lists some of Martin’s contributions to our industry:

As stated in the ACI bylaws, a Fellow is an individual who has made “outstanding contributions to the production or use of concrete materials, products, and structures in the areas of education, research, development, design, construction, or management.” The Fellows Nomination Committee selects those to be considered for the award, and then forwards its recommendations to the Board of Direction for final action in the fall.  Nominations may come from the committee itself, from local chapters, from the International Advisory Committee, or by petition signed by at least five current ACI members. The ACI Board of Direction approved the nominations of this latest group of honorees in fall 2018. Including the new honorees, 651 members are current Fellows of the Institute. The rank of FACI was first established by the Institute in 1973.

Martin A. Cuadra is a Senior Principal and a founding partner of Uzun + Case, LLC, with offices in Atlanta, GA, and Raleigh, NC.  He has 36 years of experience in structural design, contract administration, due diligence review, structural repairs, and retrofit of existing structures. 

Cuadra is a long-time member of ACI and Past President of the Georgia Chapter – ACI.  He is a Fellow and an active member of the Post-Tensioning Institute (PTI), where he is a voting member of PTI Committees CRT-20, Unbonded Tendon Plant Certification; DC-20, Building Design; and PTI Subcommittee DC-20A, BIM. In addition, he is a member of PTI-TAB (Technical Advisory Board).  Cuadra is also an active member of the Precast/Prestressed Concrete Institute (PCI) and a voting member on the committee for the eighth and ninth editions of the PCI Design Handbook.

Cuadra is a recipient of the Leslie D. Martin Award for the publication of a PCI-published document judged to be technically outstanding.

He has been successfully involved with a large number of projects located in the United States and the Caribbean.  His projects feature millions of square feet of cast-in-place, precast, and post-tensioned concrete structures, including office buildings, medical office buildings, educational facilities, parking decks, hotels, and residential towers, as well as federal projects designed against progressive collapse and blast loads.

He received his BSCE from the University of Miami, Coral Gables, FL, in 1982 and is a licensed professional engineer in Georgia and 16 other states.

An honor well deserved, thanks Martin for being such a big part of Our GA Chapter success story!

Our Next Event

Program: Concrete Cracking

This presentation will cover various aspects related to concrete cracking. This topic is both a contentious and unfortunately, a common issue nationally. Often, the key to addressing cracking issues is learning how to properly determine the cause of the crack so it can be mitigated and prevented in future projects. Topics covered in this presentation will include:

  • Causes and control of cracking
  • Evaluation methods
  • Mitigation
  • Crack repair


Speaker: Gregory Zeisler, Senior Engineer with ACI.

Gregory Zeisler is a SeniorEngineer with ACI. He has been with ACI since 2009. Zeisler works with several technical committees as staff liaison including ACI 318 and will be the secretary for the next cycle of the ACI 318 code. 

Previously he was a Structural Engineer at Durrant. Zeisler has 8 years of structural design experience in parking and retail facilities. Zeisler received his BS in civil engineering from the University of Wisconsin-Platteville and his MS in civil engineering from Purdue University. 

Zeisler is a licensed professional engineer in the states of Indiana and Wisconsin.

The Georgia Chapter ACI hosts monthly luncheon meetings throughout the year. Luncheons are an opportunity to network with your peers, earn Professional Development Hours and further your industry knowledge.

Luncheon Recap

On Friday, March 22, 2019, The Georgia Chapter of ACI hosted Charles Hanskat, the ASA Executive Director, at the Westin Atlanta Perimeter North hotel. 

The program was entitled suggested that shotcrete was the first 3-D printing material.

Charles told us that shotcrete is not a different material, just a different placement method first used in 1907.  Like other concrete placed in traditional methods, shotcrete can take gravity and lateral loads.  There is also an absence of cold joints in the material.  With proper monitoring during placement, there should be no voids.

Shotcrete will be included in ACI 318-19.  Rebar laps should maintain no contact between bars to let shotcrete adhere to bars. Closed formwork works, but it can also be open, allowing up to a 40% reduction in formwork costs. Shotcrete should be specified as a performance spec and can be used in retrofit, as it adheres to existing concrete members.  Shotcrete also does not have problems with losing air entrainment nor does it entrain extra air.

Charles received the chapter go cup and answered questions at the end of the presentation.

"Cool Concrete Bridges in the United States"

Ok, I am punting on this one since Popular Mechanics already thought of this.  It is a cool article worth reading.  The bridge in Seattle is of particular interest.
