Concrete work on the mammoth Harrison Square project will be getting under way as early as next week.

Pieces of heavy machinery dot the landscape on the downtown land that will host a new baseball stadium, hotel, condominiums, retail stores and a parking garage.

The construction management firm in charge of the project says work will begin very soon on a below ground clubhouse and on part of the outfield wall.

Jim Iddins/Project Manager: " I'd say 90 days you'll really start seeing the outfield wall in place, uh, all the concourse for the first and third base line will be up to the proper elevation, and you'll see some foundation walls going in."

Much of the preliminary site work involves figuring out ways to channel ground water away from the baseball playing field that will be built a few feet below ground.
