Mr. John Oxion Historic Preservation Commission of South Bend & St. Joseph County Re: Oliver Chilled Plow Works Buildings 46 and 47 - Forge 2 March 20, 2002 Page 5 left in the remainder of the joint. Identifying precise locations where the mortar is still sound enough to not require tuckpointing is beyond the scope of this one -day study. Thus, for-the purpose of developing a repair estimate suitable for getting the walls in shape for the building to function as a museum, we have assumed 100% of the exterior masonry will require tuckpointing. If instead, the building is to simply be stabilized and aesthetics are less relevant, we anticipate approximately 1/2 to 2/3 of the two buildings will require tuckpointing. Spalled brick were observed in isolated locations on both buildings. One of the most severe conditions is shown in Photo 31, taken of the parapet in the south elevation of Building 46. A close -up of brick spalling is shown in Photo 32, taken on the south wall of Building 47. Some of the spalled brick do not appear to be original and may be indicative of long term problems. Spalled brick allow water to infiltrate the wall and cause additional deterioration. Severely spalled brick should be cut out and replaced. One source of replacement brick to match the brick on Building 47 is the interior wall shared by the two buildings. The windows in Building 46 are typically operable steel sash as shown in Photo 33. The sash typically appears to be in reasonably .good condition with much of the paint still present as shown in Photo 34. This study assumes all of the steel sash will remain and that all of the glass panes will be replaced and the hardware repaired to make the windows operable. The deterioration of the windows in Building 47 is much more severe. The wood sash windows are typically in poor condition as shown in Photos 35 through 38. Many of the wooden members are missing. Most of the sills have rotted where snow and water did not drain properly. This study assumes all of the wood windows will be replaced with new windows to match the original. Finally, many of the doors on both buildings will have to be reworked. Original metal clad wood doors like those shown in Photo 39 can probably be rehabilitated. Other openings, like that shown in Photo 40, will have to be totally reconstructed. REPAIR RECOMMENDATIONS AND COST ESTIMATES A summary of our specific repair recommendations for the roof, facade and structural elements of Buildings 46 and 47 is included as Appendices A and B. In conjunction with this study, Ron Radecki provided general specifications for the build out of the museum. His recommendations are included as Appendix C. A budgetary estimate has been prepared by Ziolkowski Construction, Inc. based on the above information. Given the preliminary nature of the study and that they were asked to provide a "budgetary estimate ", they indicate their estimate was conservative in nature. They believe the projected cost of the work would be significantly lower once Design Development drawings are prepared. Their total budgetary estimate of $6.9M also includes approximately $375,000 for site work which we understand would be performed by others. A copy of their estimate is included as Appendix D.
