Timothy_Klusczinski, President, Historic Preservation_ Commission - Sep. 17, 2012 page 4 buildings. Larry Darling, Senior Project Manager for The Grunwell-Cashero, Co., Inc. of Detroit, MI provided SJCPL with a cost estimate on August 3, 2012 for the de -construction and salvage of the terra cotta faeade at the Avon Theatre. His company's price included all labor, material and equipment to remove all terra cotta units on the Avon faeade, photo - document, inventory, palletize, and move them into a secure storage area selected by the Library. Total cost was estimated to be $69,189.00 This preliminary estimate done in early August 2012 did not include the examination and possible repair of the brick wall that held the terra cotta tiles, nor the costs for re -installing those tiles on the brick wall after it received any needed repairs. Mr. Darling was recently asked to also estimate the costs for repairing the brick wall as needed, repairing, reconditioning, replacing badly damaged tiles, and re -installing the terra cotta tiles on the facade. His most recent proposal, dated September 6, 2012, which also provides much more detail about terra cotta materials and what he discovered in his own inspection of the Avon faeade, developed the following proposed options and estimates of cost for restoring the Avon's facade: Option 1: Remove and salvage all terra cotta veneer units from the faeade: $69,189.00 (This was the original preliminary proposal.) Option 2: Remove and repair as necessary all terra cotta veneer units: $88,690.00 Option 3: Remove and repair as necessary including glaze and spall repairs all terra cotta veneer units: $107,190.00 Option 4: Remove and repair as necessary including glaze and spall repairs and reinstall on existing building sub -structure. Work includes all new steel lintels, framing and anchoring devices, caulking and sealants (Mr. Darling's enclosed report explains the need for anchoring devices): $198,500.00 Add an estimated allowance for repair and reinforcement of masonry sub -structure (brick wall behind the terra cotta) including steel and masonry replacement as required: $120,000.00 Total Cost: $318,500.00 Includes Option 4: $198,500 plus masonry sub -structure allowance of $120,000) Comments about how terra cotta reacts to moisture when it had become seriously fractured or has experienced spalling are included in the most recent proposal. The Grunwell report further states, "wind -driven rain, freezing causing expansion and even the presence of birds can cause unstable units to fall from a faeade." According to the weather records covering the period between the date that the 8.5 lb. block of terra cotta was still in place on the building and the date that it was found on the ground, South Bend experienced a heavy, driving rain with winds of 20 miles per hour on August 20, 2012.
