4.      Basement construction vibration requirements
4.1      Noise recommendations
The effects of noise differ amongst people, with some able to tolerate sounds that are unacceptable to
others. Noise can significantly impact the health and wellbeing of affected people, and is linked to hearing
damage, stress, sleep disturbance, reduced work performance and general poor health.

There is significant difficulty in attempting a balanced approach for measurable noise levels of construction
sites against the industry needs. This guideline does not set noise limits for the construction of basement
construction noise however these may form part of a separate overall noise management plan requirement.

Limits set for vibration will reduce the level of noise generated at basement construction stage without
prohibitive requirements being placed on industry by setting noise limits.

Despite the vibration limits best practice is still encouraged for basement construction noise, Australian
Standard AS2436-2010 provides technical framework to estimate noise from construction sites and should be
utilised to estimate and manage the effects of basement construction noise on surrounding properties.


4.2      Vibration limits
Vibration levels referred to within this guideline relate to the effects on human comfort and not to structural
aspects.

Humans are capable of detecting vibration at levels which are well below those causing risk of damage to a
building. The degrees of perception for humans are suggested by the vibration level categories given in British
Standard, BS 5228.2 – 2009, Code of Practice Part 2 Vibration for noise and vibration on construction and open
sites – Part 2: Vibration and are shown below in Table 2 (shown in terms of Peak Particle Velocity in mm/s
(PPV)).

 Vibration level       Effect
 (PPV), mm/s
 0.14                  Vibration might be just perceptible in the most sensitive situations for most
                       vibration frequencies associated with construction.
 0.3                   Vibration might be just perceptible in residential environments.
 1.0                   It is likely that vibration at this level in residential environments will cause
                       complaints, but can be tolerated if prior warning and explanation has been given
                       to residents.
 10                    Vibration is likely to be intolerable for any more than a very brief exposure.



Vibration limits are summarised in Table 3 below. If a methodology is agreed upon with neighbouring buildings
(i.e. to address the impacts while work is being carried out for example, respite periods or alternative
mitigation/work method)), the vibration limit may be increased subject to an RPEQ structural engineer
addressing structural aspects and approval by the City. See Section 5.7.
