The historic Packer Scott building, now the World Headquarters for Mercy Corps, had significant damage to the original masonry resulting from inappropriate sand blasting cleaning techniques. PMA provided a complete building exterior assessment and identified areas of 50% or more cross section loss to the masonry and guided the design team towards suitable replacement material. In addition, PMA investigated foundation drainage issues during construction using non-destructive investigation techniques, and worked with the sub-contractors to provide proper techniques in the use of lime-based mortar.

Building Envelope Corrections:
• Analysis of exterior masonry and identification and specification of proper repair material and techniques.
• Analysis of the original construction means and methods of the sheet metal entablature as well as techniques for repair.
• Conducting full building window assessment and development of the drawings and package leading to support for window replacement.
