Allison - Ide
Structural Engineers LLC designed a post tensioned flat plate floor
system for this 350' tall residential condominium tower to allow
for irregularly spaced columns. This simplified the forming, eliminiated
costly transfer girders, and allowed the Architect to create large
open spaces in the Lobby / Entrance and Recreation Rooms.
Allison - Ide Structural Engineers LLC recommended and designed
a mat foundation for this project, utilizing high strength 75 ksi
reinforcing steel. This recommendation resulted in substantial savings
as compared to te alternative short pile foundation.
The concrete walls for this project were designed to be slipped
formed in advance of the poured in place floors. This concept allowed
an accelerated floor to floor construction cycle for this large
floor plate (14,000 SF per floor).
