HISTORIC PRESERVATION COMMISSION
|
Minutes note: Appeared Emilio DeTorre (Executive Director Turner Hall)
Appeared Eric Pitt (Building Manager)
Jeff Bean (Engineer)
Staff planner Tim Askin reported that the work focuses on the two-story north wing annex, which has shown significant bowing and cracking on its primary west facade. The proposal involves installing two bent steel C-channel braces across the facade, secured by metal rods anchored eight feet into the internal joists and rafters.
Staff Tim Askin expressed a strong requirement for the use of Type O or Natural Hydraulic Lime (NHL) mortar for repointing, rather than the proposed Type N mortar. This recommendation is based on the high Portland cement content in Type N mortar, which is considered too harsh for historic Cream City brick.
Staff Tim Askin cited a precedent at the Pabst complex where the Wisconsin Historical Society rejected Type N mortar, emphasizing that Turner Hall’s status as a National Historic Landmark requires strict adherence to these masonry standards.
Staff Tim Askin recommended approval of the project as a temporary stabilization measure, noting that the steel will be painted to blend into the brickwork as much as possible.
Jim Bean Engineer clarified that the building uses balloon frame construction and the facade is currently separated from the internal wood members with no direct attachment.
Emilio DeTorre the executive director, noted that the annex is a 1902-1903 addition and sits on a different footing than the original 1882 structure, which has exacerbated the cracking.
Emilio DeTorre and facilities manager Eric Pitt mentioned they are pursuing a historic structures report or a master plan to guide a comprehensive restoration of the entire building in the future.
Board member Matt Jarosz questioned if stabilization was needed on the first floor, Jeff Bean explained that the deformation is concentrated at the second floor and roof levels where the wall construction differs from the stone block base.
The board acknowledged the improved stewardship of the building, noting that Eric Pitt is the first full-time facilities manager in the organization's recent history.
The motion to approve the project was passed, incorporating the staff's conditions regarding the specific mortar types and aesthetic treatments. | | |
