New methods of conservation and presentation of the Terrace Building Complex were explored during the 2009 season to maximize the archaeological value of the existing walls (with no or limited rebuilding) and floors and improve legibility (with no or limited reburial).  The conservation goals were achieved through a series of interventions chosen to reduce the visual impact of a specific treatment, minimize maintenance requirements and limit the need for future interventions.  Treatments under this 2009 pilot program included replacement of several limestone blocks, the use of adhesives (epoxy resins) for reattachment, grout injection of cracked and delaminated stones, pinning and cable support of displaced walls, and a capping system to protect the fragmented multiple leaf walls.  During the 2010 season, the pilot treatment program will be analyzed and modified before a full program is implemented.
