ABSTRACT
Because most design changes during construction work
were due to the environmental impact of ground vibra-
tion and noise, the level of ground vibration was chosen
as one of the major parameters considered in the design
of the drilling and blasting pattern. Inspection of nearby
structures and the safety limit for ground vibration for
these structures give an allowable level to be controlled
in construction blasting. A charge weight per delay is
then determined from the allowable level and predic-
tive equation of blast-induced ground vibration.
