Mall of America

The Mall of America Modernization Project, included expansion of the mall structure which doubled the existing space. The mall expanded above Lindau Lane, creating a 400ft long underpass or tunnel under the north side of the structure. With the intent to keep Lindau Lane a publicly accessible road, this created a security concern with possible threats in the tunnel.

Hinman collaborated with Chameleon Associates to perform preliminary sensitivity air blast analysis to aid the design team and owner in selecting an economical structural system

Hinman collaborated with Chameleon Associates to perform preliminary sensitivity air blast analysis to aid the design team and owner in selecting an economical structural system for the portions of the building above and adjacent to the tunnel which provided an acceptable level of protection based on design threat scenarios developed in collaboration with Client’s security group.

The intent of this study was to provide comparative analysis of options for walls, floor systems and columns to protect the Mall of America at the Lindau Lane underpass. The results of this analysis were used to determine the most economical structural system that provided desirable performance.
