Typical pile <br />drivers are in the range of 20,000- 300,000 (ft -lbs). 300,000 (ft4bs) was used to estimate the PPV from pile drivers used <br />for construction of the proposed project. <br />Source: Michael Brandman Associates, 2009. <br />The nearest residential receptors to project structures would be expected to experience a maximum <br />vibration of 5.25 PPV from the vibratory roller, and the nearest residential receptor to the 8 -story <br />tower would be expected to experience a maximum vibration of 1.12 PPV from the pile driver. Both <br />are above the 0.5 PPV significance level for potential structural damage according to Table 4.5 -2, and <br />would cause severe human response. The maximum vibration the nearest residential receptors to <br />parking lot paving areas would be expected to experience is 0.53 PPV, which is also above the 0.5 <br />PPV significance level for potential structural damage. <br />The building construction vibration level of 5.25 PPV represents a potentially significant impact to <br />the residents of Buildings A and C of Town and Country Manor. Further, the parking lot paving <br />vibration level of 0.53 PPV represents a potentially significant impact to the residents of Buildings A, <br />B, C, D, E, and G of Town and Country Manor, and vibration levels in excess of 0.5 PPV resulting <br />4.5 -16 Michael Bmndman Associates <br />H\ Clievt (PN- JN)b32]b32]003MEMVB2]0030 Sec01 Noi�. <br />
