(SEE) was retained to provide a second opinion
regarding the existing condition of the exterior prefabricated reinforced masonry panels. the
exterior facade consisted of masonry spandrel panels between the concrete columns and masonry wall
panels covering the concrete columns and walls of a five-story post-tensioned parking garage. The
masonry panels exhibited extensive cracking and spalling that created an unsafe condition around
the parking garage.
The first well-established engineering firm recommended removing all
masonry panels and replacing them with precast concrete panels as a best long-term
solution. However, it was a very expensive repair option. Hence, the ownership wanted
to know whether there is a better way to repair the panels cost-effectively. After
evaluating existing conditions and reviewing internal reinforcing and steel
framing SEE came up with
an innovative long-term repair option where the prefabricated masonry panels can be repaired
successfully and protected without replacing them at a fraction of replacement
The ownership retained SEE to prepare
repair documents and oversee the construction. The repair program included repairing of
deteriorated and cracked masonry units, masonry joint repairs, masonry unit replacement, masonry
coating, and sealing. The repair work was completed in two construction
SEE provided masonry facade evaluation and condition
assessment, prepared the repaired bid documents for the exterior prefabricated masonry
panels, assisted the owner with bidding the project, and oversaw the construction.
