Nineteen thirty\u27s vintage reinforced concrete brewery stockhouses, collectively known as Borsari Cellars, were demolished to make space for the construction of a new stockhouse. (A brewery stockhouse is a refrigerated building containing beer storage or aging tanks.) The stockhouses to be demolished shared three common walls with two other stockhouses which were to remain intact during the demolition. It was necessary that the three shared walls remain attached to the remaining stockhouses and that the demolition take place without causing vibration damage to glass-lined tanks in the remaining stockhouse, adjacent stockhouscs, and to several underground tunnels present below the demolition site. The following tasks were performed to successfully complete this project: (I) design and install a rock-anchored tie-back system for retaining the three shared walls: (2) evaluate ambient ground vibrations during normal business activities in the subject stockhouscs and general project area: (3) recommend an allowable demolition vibration criteria and develop a monitoring program; and (4) implement the monitoring program. A resultant peak particle velocity (RPPV) of 1.0 inch per second was recommended as the threshold for low-risk demolition. This program was used successfully to demolish the Borsari Cellars without causing damage to adjacent stockhouses, glass-lined beer tanks, and underground tunnels on the project site. This approach could be used for similar situations or for demolition in areas where industrial buildings with sensitive equipment are in close proximity
