The
predicted overall noise level from the new road, together with other traffic
noise in the vicinity must be above a specified noise level (for example, 70
dB(A) for domestic premises and 65 dB(A) for educational institutions, all in L10
(1 hour)); and
·
The
predicted overall noise level is at least 1.0 dB(A) more than the prevailing
traffic noise level, that is, the total traffic noise level existing before the
works to construct the road were commenced; and
·
The
contribution to the increase in the predicted overall noise level from the new
road must be at least 1.0 dB(A).

Note: # During School
Examination Period
The
contractor should site noisy equipment and activities as far from sensitive
receivers as is practical.
Intermittent
noisy activities should be scheduled to minimize exposure of nearby NSRs to
high levels of construction noise.
Idle
equipment should be turned off or throttled down.
Noisy
equipment should be properly maintained and used no more often than is necessary.
Construction
activities should be planned so that parallel operation of several sets of
equipment close to a given receiver is avoided.
Where
possible, the numbers of concurrently operating items of plant should be
reduced through sensitive programming.
A
noise monitoring programme should be instigated.
The
Contractor shall establish a communication channel with the nearest NSRs to
liaise on the blasting schedule and inform them any scheduled blasting in
advance.
Sufficient
time shall be allowed for alerting all the potential sensitive receivers
through established channel of communication prior to each and every blasting
activity.
Proper
procedures shall be put in place to alert and minimise any startling effect on
the vehicle drivers and pedestrians.
Subject
to detailed design to be conducted by the Contractor (i.e. a Design and Built
Contractor), trial tests could be conducted to evaluate the optimal amount of
charge to be used for each blasting.
