President's Report

We had a good meeting on Friday, March 25, with Eohan from SkyMul.  His presentation was very unusual for us, as it had robotics and a lot of futuristic vision of what the jobsite may look like.  There was a lot of discussion, including his interest in hearing what the audience thought about good uses for robotics in the construction site.

On April 23, Jon Tuggle from Martin Concrete Construction/MC Ready Mix will present the benefits of an on-site mixing plant for a jobsite.  He will discuss the evolution and drivers for onsite portable concrete plants along with considerations that designers, specifiers, and contractors should know when evaluating a portable plant operation.

As we move into spring, it always a good time to make sure that your certifications are up to date.  If you need to recertify or add to your certifications, please check the website for upcoming classes.

In April, we awarded our two scholarship awards to Ogulcan Canbek and Renee Rios, both of whom are graduate students at Georgia Tech.  Congratulations for their impressive work !

If all goes well, the ACI National Convention in October 2021 will be in Atlanta.  We are hoping this will be a live, in person event and not “virtual”, as most of 2020 seems to have been.  There will be updates on this later this year, as we learn more.  Importantly, there will also be opportunities to sponsor and to get event booths.  We expect the live vs. virtual question will not be answered until after July 1.

Everyone continue keeping safe and I hope you all have good health and well-being.

Luncheon Recap

March 2021 meeting report

“The SkyTy Solution” 

We had a little over 20 in attendance for our March Lunch Meeting; to hear a most interesting presentation from Eohan George, CEO of SkyMul on the use of drones to tie rebar in the field.

Eohan opened with a short Bio on SkyMul explaining that it was founded by Georgia Institute of Technology alumni with a broad background spanning robotics, computer vision, drones, manufacturing, 3D scanning and international business.  From previous endeavors the group is listed on over 10 granted and pending patents.  Individually the team has worked on automotive R&D, aerospace tooling, medical devices, and unmanned vehicles.  The team holds degrees from Georgia Institute of Technology and Georgia State. In fall of 2018, SkyMul was awarded a Small Business Innovation Research (SBIR) grant and was accepted into The Farm accelerator program.

 

He explained that the team is new to construction, but is not new to manufacturing. Specifically, aerospace manufacturing has many parallels to construction.  In both workers and tools must travel to the structure and carefully move large sub-assemblies with heavy machinery.  Bringing the fundamentals of smart tools, flexible automation, and robotics to the construction space presents key opportunities in the structural concrete area and beyond which SkyMul aims to unlock.

Eohan then went into some specifics on SkyTy which is there rebar tying drone system; he explained that on a typical flat matt type layout, the bars are shook out by hand and minimally tied by hand for shape and pattern.  SkyMul personnel then map the general matt layout with a “mapping drone”, this data is transferred to a SkyTy Drone flies the cordoned off area tying 100% of the cross bar intersections.  He says rough figures suggest construction costs savings of 84% less labor, 2.4 times faster production and 32% cheaper install costs overall.

 

Eohan shared a really cool video of the drone in action:

Eohan closed out with a pretty healthy group discussion on the construction industry in general and were there may be other avenues to explore and use this type technology.

This year has been a banner year on the variety and diverse presentation topics, be sure and mark your calendars for our next meeting on April 23.
