ARCHITECTS
The design challenge of Woodridge was to create a big box that "fit" into the context of the new shopping area. "By utilizing different block textures, pushing the facade in and out, defining the base with a brick wainscot and using the decorative pilasters to define edges, we broke the massiveness of the building creating a human scale at the sidewalk level."
With offices in Kansas City and London, TK Architects works all over the world creating state of the art cinemas, entertainment and leisure facilities, corporate and retail designs, food services and tenant planning.

ENGINEERING
The masonry walls on this project were designed using an in house spreadsheet that is an exact working stress analysis based on the ACI 530 Masonry Building Code. The spreadsheet determines the allowable wind and seismic loads for vertically spanning reinforced CMU walls. The spreadsheet calculates the maximum allowable wind and seismic loads based on a given effective height, section properties, axial loads and eccentricities, and construction technique.
Through its offices in Tulsa, Kansas City and Irvine, Wallace Engineering designs hundreds of projects with masonry walls every year. Tom Wallace, P.E. and President is a frequent lecturer nationwide on the design of tall masonry walls. Principal Tom Gongle, PE, currently serves on the ACI 530 Committee.
WALL BRACING DURING CONSTRUCTION
When building tall slender masonry walls such as these, temporary wall bracing is a critical issue. The walls are engineered to resist wind loads after the roof diaphragm is installed. During the initial and intermediate periods, the walls must be braced to protect against injury and loss. The state-of-the art bracing system used on both sides of the wall (see left) provides support for this wall in both out of plane directions.
A wind meter mounted on a pole is connected to a siren which automatically sounds at 28 m.p.h. windspeed. When the alarm sounds all workers must evacuate the wall and proceed out of the limited access zone.
