Studies Focused on Allowable Vibration Levels during Construction Activities in Mexico

When considering construction activities some of them generate vibrations ;the use of explosives , drilled shaft foundations , sheet pile driving, compaction, displacement of heavy machinery , etc. All of them may induce damages to installations or buildings as well as annoyance to persons in the surroundings. Although many references are available recommending maximum vibration levels for different cases, no general standard exists to establish criteria for regulating vibrations during construction processes. This propitiates that participants involved in a project have different criteria on permissible vibration levels and since not sufficient information is available to make a reasonable prediction of the effects, very restrictive operating limits are therefore applied but with no solid ba -ses. A standard is available in Mexico to delimit the maximum time of exposure of persons subjected to vibrations derived from machinery works but not precisely applied to construction activities. For purposes of the paper presented herein , such standard was used as starting point so as to determine its applicability in vibrations produced by construction processes. Reference was made in this work of standards issued by 10 countries and vibration records of six case histories in Mexico were includ ed adding up to a total of 639 validated data that made it possible to propose an approach for the analysis by different experts in this field as background information to endorse in a medium term ap proval of a standard for controlling the effects of vibrations in construction processes. It is concluded as an outcome of this work that a very accurate control can be implemented by comparing vibration velocity and acceleration with suggested limits.
