How Restoration Progressed: Phase IThe Chapman's Mill stabilization project is a unique and valuable undertaking in the field of historic preservation. TTMAC has chosen to preserve the Chapman's Mill as a ruin site, showcasing the architectural, engineering and historic elements of the building as it stands after the fire of 1998. Cutting-edge technology is being used for the structural stabilization of the mill building. An internal anchoring system, developed in Europe for historic masonry buildings, has successfully been implemented in Phase I of the project by Cintec America. Recently completed in May 2004, Phase I includes the structural stabilization of the south wall (actually seven stories high and in the worst condition) and corners, lead capping on all upward facing surfaces of the entire building and emergency shoring of all window openings (49 total).
The engineering for the stabilization of the north, east, and west walls is ongoing and the work will be completed in the spring of 2006 as the weather dictates. Chapman's/Beverley Mill is believed to be the tallest stone building in the United States.
The contractors chosen for this specilaized historic preservation project are experts in their fields. They are Cintec America, Inc. - Structural Anchoring Systems, Conservation Solutions, Inc. - Project Management, Standard Restoration and Waterproofing - Masonry and Scaffold Resource, Inc. - Scaffolding. Phase II stabilization of the last three walls, should be completed by July 2006.

|Inflated Anchor: This picture shows how the anchor sock confirms the irregular shape of the building stones.||Rotary Drill: A Rotary dry drill is used to reduce the vibrations which could cause more damage to the building. The building is also drilled dry (no water is used) to reduce the damage that might be caused using water.|
|Finished Hole: This is finished drilled hole.||Installed Anchor: The anchor which is made of a stainless steel is surrounded by a patented sock which is filled with a patented grout that expands and bonds to the surface.|
|Scaffolding: Scaffolding erected to allow the workers to drill and install the Cintec Anchors.|
