3. Reports on vibration caused by heavy machinery (LBNL – ALS) 28th April 2015EDMS1487758 3 “Building 51 Demolition Vibration Study” [12 May 2006] “LBNL Building 10 Demolition Vibration Test” [7 Sep 2006] “SERC Paving (Vibration Measurement Results)” [19 Nov 2014] 0.1 µm 15-20 nm

4. Heavy Machinery (Bld. 10 Demolition) 28th April 2015EDMS1487758 4 Hoe Ram Concrete Saw Jumping Jack Excavator

6. IES Criteria for Vibration 28th April 2015EDMS1487758 6

7. VC Curves 28th April 2015EDMS1487758 7 0.1 µm 6.3 µm/s (~250 µin/s) @ 10 Hz 3 µm/s (~125 µin/s) @ 5 Hz Ground Vibration

8. VOLVO DD25W (HK5V83) at P1 vs Distance 28th April 2015EDMS1487758 8 IMPORTANT: Integration time – 1s

9. Overall Velocity/Displacement vs Distance 28th April 2015EDMS1487758 9 Velocity vs Distance Displacement vs Distance

10. 3 rd Octave Band Velocity, loc. I2 (example) 28th April 2015EDMS1487758 10

11. Power Spectral Density & IRMS (BLD51-ALS) 28th April 2015EDMS1487758 11

12. Which of these can be of use to us? 28th April 2015EDMS1487758 12 1.3 rd Octave Band Velocities comparison with the VC-Curves, but more important with the constant displacement line give a rough estimate of velocity/displacement value within separate 3 rd octave frequency ranges 2.PSD & IRMS give a global integrated value of vibrations for the whole frequency range (overall level of vibrations) However: in our case for these calculations, we need to know the Transfer Functions and the input PSD from the machinery
