President's Report

The summer heat has departed and fall weather is in full swing which means this year is almost over.

Please submit your 2018 concrete projects to our Dan R. Brown ACI Awards Program. Project
submission criteria is listed on our chapter’s website. Our Awards Banquet will be on February 28, 2019.

If you missed our October meeting, Dr. Larry Kahn gave a great presentation on ACI 562 including assessment, repair and rehabilitation of concrete structures. As concrete buildings mature, repair and rehabilitation of older structures has become increasingly important.

I hope you will join us at our next luncheon on November 16th. Dewayne Thomas and Ross Medlin will be speaking on The Advancement of Porosity Inhibiting Admixture Capabilities. This luncheon will be held at the Westin Perimeter North.

Best Regards,
Tom Pfeifer
Georgia Chapter ACI, President

Luncheon Recap

We had a capacity crowd of 50+ for this year’s joint GA Chapter Meeting with GA Chapter ICRI.  Joint Chapter’s Member Dr. Larry Kahn, past ACI 562 Chair and currant ACI TAC Chairman gave us a comprehensive review of the relatively new ACI 562 Code Requirements for Assessment, Repair & Rehabilitation of Concrete Structures. Click here to view the presentation.

Larry opened with a brief review on some repair industry issues pre-repair code; things like: a lack of new design education and understanding by design professionals, limited assessment and structure evaluation, poor understanding of long term durability, disdain from the historic preservationists, poor contractor focus on lasting quality, and little guidance from US National Codes. The International Building Council made an attempt at providing some of this in the 2015 IEBC, International Existing Building Code.  However, some key elements like: the HOW of minimum evaluation requirements (i.e. how bad is it, analysis considerations & reliability of repairs), durability considerations, structure service life and construction quality assurance were notably missing from the document.   The industry need for a comprehensive concrete repair code was needed to establish a standard of care, provide for longer living structures and to provide help when assessing a structure for required repairs

The first ACI Repair Code was published in 2016, ACI 562-16 Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary.  The new Code set minimum requirements for repair and quality, provided clear requirements for strengthening, gave guidance on existing structure uniform assessment & evaluation, and defined what a durable repaired structure meant.  Larry then spend some time reviewing some known issues with both 2015 IEBC and ACI 562-16 and limited statewide acceptance by local building officials of either.  All of this laying the ground work for some badly needed code changes in IEBC 2021 and ACI 562-19.

Larry closed with a detailed case study review of a 2-story flat slab parking deck, located under an 11-story office building that showed deflection and excessive surface cracking.   He summarized all aspects of the project from document review, site conditions, as-built assessment and basis of design.  Finally, he wrapped up with some details on the actual repair design and specifications or repair for the project including: shoring, environmental issues, inspection, material testing, and finished repair testing & assessment.

In closing Larry reminded us that the concrete repair industry makes up +$20 Billion annually in construction spending annually and 30% of all ACI Technical Committees have something to do with concrete repair.  Past-President, Wayne Wilson closed with a speaker presentation of our GA Chapter Travel “Mojito” Mug and all departed with a head full concrete knowledge eagerly looking ahead to our next meeting on November 16, 2018.

Our Next Event

On Friday, November 16, 2018, The Georgia Chapter of ACI and the Atlanta chapter of ICRI will host Dewayne Thomas of Eco and Ross Medlin of Barrier One at the Westin Atlanta Perimeter North hotel.  They will talk about advancement of porosity inhibiting admixtures and their capabilities.

Dewayne is a native of Savannah Georgia.  He earned a Bachelor’s of Construction from Southern Polytechnic State University in Marietta Georgia in 1995 (now Kennesaw State University). He has amassed 20 years of experience in technical sales, and is certified by the Construction Specifications Institute as a Certified Construction Product Representative. His focus has been in ecologically sustainable products, specifically centered around Concrete Enhancement Technology, Rain Screen Exterior Wall Assemblies, and Energy Efficient Roofing Systems.

Ross was born and Raised in Charlotte, NC to a family of subdivision developers. Ross learned the ropes of construction early in life. Upon Graduating from high school, Ross enlisted in the Marines serving one decorated tour in Iraq and another deployment to the Republic of Georgia achieving the rank of Staff Sergeant before getting out after nine and a half years. During his time in the Marine Reserves he Graduated with a Bachelors in Business Administration from the University of North Carolina at Charlotte. Upon graduation, he worked a short stint as a Logistics Executive for a high volume Super Target store in South Charlotte. After 5 years, he decided to return to his roots and joined Barrier One to work his way up from Sales to Operations Manager. His focused efforts are in formulation development and innovation in other areas of concrete technology.

Tilt-Up Series Atlanta

O V E R V I E W

Architects, engineers, developers and contractors across the country are taking tilt-up to new levels. They’re utilizing this most flexible building system to realize new markets, executing high-end, Class-A finishes and calling on the intrinsic properties of tilt-up to meet increasingly stringent energy codes. Best of all, they’re willing to share their experience and expertise with you.

The Tilt-Up Concrete Association (TCA) is taking these strategies on the road, hosting a series of tilt-up education/networking events across the country. The last stop in 2018 is Atlanta, Georgia.

E V E N T   S C H E D U L E

3pm    Meet and Greet - Show up a little early to pick up your badge and network with fellow attendees and speakers. Light refreshments will be served.

4pm    Demystifying Jointness Floors - Jason Adams with Sinclair Construction Group will serve as moderator of this roundtable discussion investigating the options, design, benefits and challenges of working with jointless, or expanded joint, floors. 

5pm    High-Strength Welded Wire Reinforced Tilt-Up Wall Panels - The use of grade 80 welded wire reinforcement in tilt-up panels is becoming the go-to choice for many designers and contractors. During this talk, its value and benefits in the tilt-up market will be explored. We will cover the design and fabrication of this product as well as highlight special design and construction issues that should be considered.

6pm    What is Value Office and Why? (Dinner) - Value Office is a term we’ve coined for the conversion of a typical conventionally constructed (that is steel or concrete framed perimeter column non-load-bearing wall construction) market office building to tilt-up technology. The original task, one of commodifying the building method through a building type, was an uphill struggle at first. We had to prove to commercial developers that utilization of a low-cost construction technology to build an investment grade office building could compete with the definition of Class A in the market place. The aesthetic flexibility of tilt-up combined with its ability to improve upon the characteristics of typical offices ultimately won a niche for Value Office in numerous national market regions. It improved upon the conventional product as it has no perimeter columns making it more efficient to plan, due to wall strength accepts any exterior cladding material and offers column free all glazed corners to name a few of its appealing attributes to developers. Most significantly, and importantly when combined with the above advantages, it averages $7-$10 per square foot less expensive for the exact project built conventionally in most suburban markets. This is no subtlety; it represents a grass roots insurgency on the part of low-cost technology fueled by historic economic forces. It occurs in a space that many architects have occupied – developer work, investment grade commodity architecture – but as contractors and developers have been more open-minded regarding adaptations like tilt-up into “high-end product” it inadvertently threatens to leave that area of architectural practice behind if ignored. Our effort has been to engage the economic metrics head on in order to control the possibility of an aesthetic potential in this building type that makes up so much of the everyday suburban landscape.

7:45pm    Reception (Off-Site) - Following the event, we will head off-site for a quick drink at a nearby local establishment.

Outside the Cylinder

“Concrete (or Cement) Shoes”

I decided to explore the use of “Concrete/Cement Shoes” as it applies to organized crime and where the term came from. To my mild surprise, it is largely fictional in origin. It has, however, become a term of sorts to describe a murder by organized crime.

In 1968 film “Lady in Cement”, starring Frank Sinatra, involves a murder of a woman with her feet encased in concrete. 

The 1989 novel “Billy Bathgate” also features a murder where the victim is thrown in the river with his feet encased in concrete. The novel was adapted to the movies in 1991 and starred Dustin Hoffman.

The only documented case of “cement shoes” did not occur until 2016 when a body of a Brooklyn gang member washed up near Manhattan Beach.  The victim’s feet were encased in concrete set in five gallon buckets. His body floated apparently because of air in the concrete and because the concrete was not given enough time to dry before throwing him in the river (presumably much of it fell out of the buckets).

There are several undocumented cases of victims believed to be given “concrete shoes” back in the 1940’s, but it is only speculation.
