PRECAST WALL OPENING

Our Food & Beverage client located in Atlanta, GA needed a large opening to be cut through an existing tilt-up concrete wall for operating un-manned forklifts.  The required clear span was approximately 40’.

Dynamic Engineering Design (DED) was responsible for the structural design and providing the onsite construction management.  DED worked with the contractor to design temporary supports for holding the upper portion of the existing wall in place while the entire lower section was field cut and removed.

The work included a structural analysis of the existing wall foundation, concrete wall, and conventional steel column and roof joist systems.

New steel posts where installed, which also required new concrete spread footings.  A 33” deep long span steel beam was used for the clear span.  Although the beam was cambered, flowable grout was used above the top flange to prevent upper wall movement after removing the temporary supports.
