n three years, a Davao City structure will finally get closer to the sky.
We’re referring to the latest property development project getting to the earth-moving phase— that’s the stage where images on drawing boards and blueprints are gradually transformed into tangible structures. Aeon Towers of the FTC Group of Companies is set to become the city’s tallest skyscraper at 90.8 meters or 33 levels of mixed-use property. Before Aeon Towers, The Marco Polo Davao, at 18 storeys, holds the distinction of being the city’s tall-
est. So, how does the Aeon Towers fare when ranged against the tallest buildings in the country? Midget. Aeon would be nowhere in the top 50. PBCom Tower in Manila is the country’s tallest at 259 meters although it has fewer floors (54) compared to no. 2 ranked Gramercy Residences with 72 floors but lower in height at 250 meters. Discovery Primea (250 meters, 68 floors), Kingsbridge (220 meters, 64 floors) and GT International (217 meters, 47 floors) occupy the rest of the top 5. What are the limitations for
builders to construct high-rise buildings in Davao? Ademar Pama, structural engineer of Aeon Towers, said that basically the challenge is dealing with the soil quality and Davao being in the critical zone of the so-called Ring of Fire. “The challenge in this part of the area (J.P. Laurel Avenue) is the first few layers of the foundation’s soil are really not quite good, it’s soft. But deeper, it’s already quite stable, that’s why we have it on piles,” Pama said in explaining how they prepared the Aeon Towers design. “The foundation is basically a board pile. The board pile would
extend to the hard strata,” he explained. The maximum depth of the board pile, according to Pama, is about 40 meters from the basement level (from the bottom of the excavation). That means, the total depth of the foundation is 56 meters from ground level. “We really need to have that depth,” Pama stressed. With a 56-meter foundation, the Aeon Towers engineering team was able to come up with the ideal height of 90.8 meters from the ground. However, as they go up, there’s another challenge--staying
