After two of four planned Detroit high-rises were built with steel frames, owners began to hear concerns from tenants about wind-induced movement at the upper floor levels. To resolve this problem, the designer of the third high-rise decided to use a concrete frame. By switching to concrete, the owner realized savings in both construction time and overall costs, as well as the benefit of shielding the two buildings with steel frames from the wind. Substituting cassions for the costly pile foundations used on the first two buildings also contributed to overall economy.
The overall time frame for construction of the 27-story building was 19.5 months, but the first 10 floors had to be completed and ready for occupancy in 15 months. With a commitment to completing a floor every 6 working days, the schedule drove the concrete. For all of the building frame, early development of concrete strength was the key to maintaining the fast-paced schedule. Crane scheduling was also essential to the profitability of the job. To get all contractors working from the same crane, the crane schedule had to be carefully developed. Concrete was pumped up the interior of the building by a pump located near the base of the tower crane. All concrete was placed with a 32-meter self-climbing placing boom, centrally located to reach the entire floor.
