STORM CHANNEL GETS BURIED

For the installation of beam and steel plate for the temporary shoring, the city and county public officials were very concerned about noise and especially vibration. The backyards had failed block walls that were leaning precariously and didn't need too much vibration to fall over. This prompted the requirement of a demonstration of the beam installation technique by the inspectors, which showed that with the pre-drilling, very little vibration was needed to install the beams and very little vibration was transmitted through the ground.  Additionally, August was able to demonstrate to everyone's satisfaction the variable moment and power control inherent in the Mobilram unit, which gave the operator complete control with the vibration.  As it was, full power and 100 percent vibration with predrilled holes did not transmit sufficient vibrations beyond the hole locality to be of any concerned.  The general contractor Herman Weissker gave August the green light to vibrate the beams using the Mobilram variable moment vibrator, and installed the 35 to 40 foot beams, provided by Trench Shoring.
