Project to Cement Atlanta’s Reputation as Tech Hub By Cindy Riley

tion of office space,” and will serve as a landmark for the city of Atlanta. “We believe innovation is generated by looking at things in a different way,” said Pierluca Maffey, vice president of design of John Portman & Associates. “So we are creating spaces that allow brilliant thinkers, creative minds and smart business people to come together, share their points of view and start a process that leads to the next big idea.”

In Atlanta, Ga., construction continues on a $375 million mixed-use project that will mesh research with commercialization. When it opens in 2019, Coda at Tech Square will provide 770,000 sq. ft., of office, retail and technological areas, positioning the city as a major tech hub. “Coda is a unique development, and is part of Portman’s vision to advance Midtown Atlanta as a leading national location for technology and innovation,” said Hunter Richardson, executive vice president of development, Portman Holdings. “With each construction milestone, we get more excited about the potential for this development to add more energy to this part of the city.” With five levels of underground parking, the high-profile endeavor has required a mass excavation of 160,000 cu. yds. of dirt, so far. This amounts to 16,000 dump truck loads of soil hauled off, which, if lined back-to-back, would stretch from Atlanta to Macon. Because of the extraordinary amount of dirt moved and approximately 90,000 man hours invested, officials held a “bottoming out” ceremony to mark the end of this phase of construction. “Our team and the many stakeholders who are making Coda a reality came together to acknowledge the hard work done to date, and to remind each other of just how transformative this development really is,” said Richardson. “This was the inflection point when we transitioned from excavation to vertical construction. We are now building up toward an

even more vibrant future for Midtown Atlanta.” According to Georgia Institute of Technology president G.P. “Bud” Peterson, “Since it first opened 13 years ago, Technology Square in Midtown Atlanta has rapidly become one of the leading regional innovation hubs in the southeastern United States. Tech Square promotes and facilitates innovation and collaboration between businesses and industry and the Georgia Tech community.” The school will be the anchor tenant, occupying approximately half the 620,000 sq. ft. of office space. Portman Holdings owns the tower, with John Portman & Associates designing the facility. “Coda, which includes a high performance computing center,

will take innovation to a whole new level,” said Peterson. “This iconic building developed by Portman Holdings will become a magnet for corporations and startups alike, while serving as a stateof-the-art resource for breakthrough research. This new facility will help propel the region and Midtown Atlanta as one of the leading innovation ecosystems in the Southeast and the nation.” In December 2016, hundreds gathered for a ceremony to celebrate the formal start of construction for the 21-story office tower, which will have close proximity to MARTA and major highways. The structure is located near Atlanta arteries I-85, I-75, Hwy 78, Spring Street and West Peachtree Street NW.

soon total three million square feet of commercial space and more than $1 billion invested. The mixed-use development will serve as an urban “main street” for the campus and community. DPR Construction was hired to build Coda, which will occupy an entire city block, and include a unique preservation of the historic Crum & Forster building. DPR will clean and restore the 1927 exterior, while transforming its interior as restaurant and entertainment space. “We always preach that ‘you don’t know what you don’t know’, and there are a lot of unknowns involved with excavating a city block down five floors,” said Tom Montanye, DPR project manager. “Overcoming and adapting to these unknowns has presented the biggest challenges to the project, so far.” Montanye noted that existing utilities have been a concern, as well as soil conditions both on site and off site (within the boundaries of the shoring wall tie-back system), along with the location of rock and quality of rock and how quickly crews can draw down the water table. Construction crews began their work in late fall, with the date for substantial completion scheduled for mid-February 2019.

“Prior to breaking ground, it was important to have all existing utilities removed from the project,” said Montanye. “This included water lines, gas lines, power poles and communication lines. We are excavating from property line to property line, so any utilities remaining when we put the first shovel in the ground will impact the overall project schedule. Next, we cleared the site, began to install the h-piles for our shoring system and installed the perimeter well points to begin drawing down the

water table. “We started with 42 perimeter well points and later added eight inbound well points to help speed up the draw down of the water table. We have averaged over 50 GPM from the site since we broke ground in November. We utilized a top down construction shoring wall system. This allows us to construct the permanent retaining walls simultaneously with the mass excavation activities. When we reach the bottom of the excavation, our permanent walls are in

place, and we are ready to begin the structure.” According to Montanye, the first step in the shoring wall construction was to install the soldier piles that support the horizontal lagging on the wall. “At this point, we had just installed our perimeter well points and were still dealing with very saturated soils,” he said. “Our drill rig, a Bauer BG42, was originally outfitted with a single flight auger bit. The poor soil conditions resulted in us continuously losing the

integrity of the drilled holes. ABE Enterprises, our drilling contractor, quickly swapped out the single flight auger bit for a 60-foot continuous flight auger bit.” Dealing with the elements has been another consideration, “Weather is always a factor, especially when you spend eight months digging a hole,” said Montanye. “One benefit to your site being a giant hole in the ground is that it greatly simplifies your erosion control measures. Water flows downhill, so, in our case, that’s into the site and not off of the site. The drawback is that in a major rain event, the site can quickly become over-saturated. It’s important to know when inclement weather is coming, and properly prepare your site. “You have to make sure you have established low points with active pumps installed in those locations. We can’t control when it rains, but we can prepare our site to handle the weather and hopefully limit the schedule impact to a single-day weather event.” A variety of heavy equipment is on site to carry out the many tasks required to build Coda. “We’ve had a fleet of excavators throughout the project,” said Montanye. “The bulk of the mass excavation was performed by two John Deere 470 excavators.

are large excavators that are built for moving large quantities of dirt. They come equipped with a four-yard bucket, which allows them to easily fill a dump truck with three scoops.” The Bauer BG 42 was utilized for both shoring wall construction and the drilled shafts of the deep foundations. In addition, soil nailing/tie-back rigs have been necessary for the soil nails on the shoring wall system. There are two tower cranes on site, as well as geo tech rigs, dozers, hydraulic pumps and rock drilling rigs used to drill holes for the dynamite/rock removal. Site demolition has already been completed, along with utility relocation, mass excavation, rock blasting/removal, virtually all shoring wall construction, foundations and BIM coordination. “To date, we have basically excavated the hole. Now we have the building to construct.” Two small buildings on site were torn down by the ownership before crews broke ground. Enormous amounts of soil and rock have been removed, with 190 piles driven. Enough water has already been pumped out of the site to fill a 3/4 in. garden hose nearly reaching the moon and back.
