Provided structural engineering services for this LEED Silver 84,000 square-foot Medical Examiner’s building. The structural system consists of structural steel with concrete over metal deck floor and roof diaphragms. Special care was taken in the design of the floor structure to ensure the end-user’s vibration criteria were met.
The lateral system consists of special steel moment resisting frames in both principle directions. Moment frames were designed in accordance with the latest guidelines, AISC 358-05, as referenced from the latest codes. A very complex exterior wall was designed to accommodate the lateral systems displacement.
Degenkolb proposed using the latest design standards to design the lateral system through an alternate means of compliance as they were not yet permitted in the building code. Utilizing these guidelines that are based on recent experimental testing, we were able to reduce the amount of steel in the building lateral system using deep column moment frames. Deep columns provide greater stiffness to control building drift without the accompanying need to increase the weight of the members. Our structural solution resulted in an approximately 50% reduction in the amount of steel needed for the lateral system compared to a design using previous code required columns. The projected completed construction under budget and design was completed within our original estimated design fees for the original scope. The total project cost was $73 million. Construction completed late 2009.
