During the real estate downturn, Swire Properties Inc. took a methodical approach to assembling the site of its Brickell CityCentre development. If the company wants to outbid other suitors to add a Brickell Avenue entrance to the project, it will have to move much faster.

Calling the 700 Brickell site in Miami "a logical extension of Brickell CityCentre to Brickell Avenue," Swire has joined a group of potential buyers for 1.55 acres in the middle of the city’s financial district now being marketed for sale. Swire executive vice president Megan Kelly said Monday in a written statement that the company, which is developing the 2.9 million-square-foot CityCentre nearby, plans "to pursue the opportunity aggressively."
