A demolition contractor wants to wreck a building in the most efficient way possible.  In this instance, they were looking to place skid steers and mini-excavators on the roof and each of the floors to facilitate the removal of debris.  We helped them to achieve this by producing a selective demolition protocol that allowed us to measure the existing reinforcing steel in the two-way slabs and then, using this data, we were able to analyze how the structure would react to the placement of these heavy loads at each level.  We worked with the contractor to establish the allowable drive-lanes and equipment proximity limits for this to work. The contractor also needed to cut a large hole in the slab at each level to serve as a debris chute.  We analyzed this condition and specified the parameters for this work.
