HISTORIC PRESERVATION SERVICES 

W|A Associates performs architectural and structural evaluations including recommendations for seismic repair and improvements to adobe, concrete and un-reinforced masonry structures which maximize the preservation of historic features of the structures.

In addition, analysis and research services are provided to investigate source materials and identify causes of deterioration on various historic structures.
