Sites and Structures Report October 2014 |
Description |
Sites & Structures Committee Report, October, 2014 The following is a summary of stabilization, preservation, restoration, and related work planned, completed, and in-progress, including requested Board approval or other action on pending work and projects under consideration: I.MJH Wall restoration project: A.The disintegrated below-grade NW corner of the foundation [Image #1, photo 335, 8/13/14] has been re-stabilized by underpinning with stacked bed-stones covering a greater area than the foundation they support (sometimes called a "spread footing") projecting beyond the vertical planes of the foundation plinth. The displaced below-grade stones underlying this corner were replaced with stones gradually stepped-back to the mean vertical plane of the foundation plinth [Image #2, photo 797, 9/5/14; Image #3, photo 802, 9/5/14; and Image #4, photo 941, 9/12/14]. The stacked footing stones are variously rotated on a vertical axis to evenly distribute the load across the bed-stone. This reconstruction will reduce the unit [pounds per square foot] loads on the clay sub-strate under this corner, and inhibit further de-stabilizing movement of the structure supported by it. B.Foundation stabilization along the river-side wall away from the corner, backfilling, and site prep will be completed by the end of this week, followed by insertion of "needled" cantilevers to support the roof during reconstruction of the radially-displaced wall ranges. C.Re-location and restoration of the doorway to its central 1716 location, and design and fabrication of new doorway and window frames and glazing will be incorporated into the wall re-alignment project. Window dimensions and design specifications, door framing, and door and hardware details will be developed and submitted to the Board during the winter. II.Keim Farmstead: A.Review proposed By-Law re: professional services performed by Board members; B. Repairing or replacing Keim ancillary roof framing is a high priority; would be Shelley-funded, with dedicated matching funds. The workshop building is explicitly integral and critical to the forthcoming application for Nation Landmark status of the early house and the contemporaneous ancillary structure. III.GDH: Consider restoration of 1765 house to stable, safe, and "exhibitable" status: A.Restore "best" parlor [NW quadrant of house-plan] to 18th century wall and floor materials, design, and detail; B.Re-establish blind partition between best and back parlors; C.Re-floor kitchen and back parlor as funding becomes available. IV.Authorize sub-budgets (or refer to Finance Committee) from general funds for: A.parking lot maintenance; B.Painting and maintenance. C.Future structural & weatherization matches. Submitted for the Committee, Laurence Ward; updated December, 2020. |
