9.2.2 Noise and Vibration
The construction of this project will result in additional noise and vibration through the use of construction
machinery. NZTA will minimise construction effects such as noise, and vibrations and traffic disruption in the
following way.
The Contractor will prepare and implement a Construction Noise Management Plan (NMP). The NMP shall aim
to minimise any adverse effects from noise during construction, and shall include:
• The implementation of the principles contained in NZS 6803:1999 and the Outline Plan and Resource
Consents during the construction of the motorway and local roads;
• Means to ensure that the Resource Consent requirements are achieved.
A Vibration Monitoring and Control Plan will be developed to minimise possible nuisance from construction
works at adjacent sensitive building and/or occupants. Maximum permitted ground vibration levels shall be in
accordance with the following table:
Table 14: Maximum Permitted Ground Vibration Levels

Type of Building or Structure
Peak Particle Velocity
(mm/s)
1 Historical buildings monument and buildings of special
value or significance.
2 Houses and low rise residential buildings, Commercial
buildings not included in (3) below
3 Commercial and industrial buildings or structures of

The above limits are relevant to damage only. With regards to human sensitivity the Contractor will determine
maximum permitted ground vibrations in consultation with the affected owner or occupier. The proposed
noise and vibration arising from the TEM earthworks will be managed and mitigated to have a less than minor
effect on the surrounding environment.
9.2.3 Dust
The suppression of the dust over the site will be an ongoing task throughout the duration of the earthworks.
Where practicable, early establishment of vegetation over exposed areas will be completed, particularly if sites
need to be left for settlement. Other means of suppressing dust may include the use of water carts, sprinklers
and dust suppressants.
Before commencing work on site the Contractor will be required to prepare a Dust Suppression Plan (DSP) to
the approval of EBOP. The DSP and its implementation shall satisfy all Resource Consent Conditions and
include as a minimum:
