Constructing a Skyline Landmark
Frost Bank Tower is an iconic peak on Austin’s downtown landscape. Rising 33 stories, the Class A office building was constructed with a cast-in-place concrete frame and combination of glass and limestone curtainwall. The building was designed with a stair-stepped exterior façade culminating in a glass and steel "crown" illuminated with 220 high-intensity lights. The first 11 levels provide parking for 1,500 vehicles and the remaining 22 levels provide 500,000 rentable square feet. At street level, there is a landscaped urban plaza with interior space finished out for restaurants and conference facilities. Our firm completed both the shell and interior common areas in 24 months.
Preconstruction services were a six-month collaboration with the entire team during the schematic design phase. This planning was particularly critical for the final design and construction of the 99ft tall crown. Prior to constructing the tower, we demolished several clubs, restaurants, retail shops and a bank. Once the site was cleared, piers averaging 52-inches in diameter were drilled and a 6ft thick concrete mat slab was poured to support the structure. With 62,000 cubic yards of concrete and 7,000 tons of reinforcing steel, the tower began to take shape as we turned a floor every six days on average.
