CEMP Expectations for the appointed Principal Contractor
The guidance and expectations out in SEMP 002 within Appendix B of this CEMP should be followed
and where necessary be reviewed and updated once a detailed construction programme and build
methodology has been agreed with the NZTA by the Principal Contractor and the Construction
Environmental Manager.
Erosion and sediment control should be provided by the Principal Contractor throughout the
duration of the construction works and maintenance period to ensure protection of the downstream
receiving environment from the adverse effects of sediment from the work area.
The Erosion and Sediment Control Guidelines document prepared by ECan should be used as the
principal basis for the formation of an Erosion and Sediment Control Plan. The NZTA Erosion and
Sediment Control Standard for State Highway Infrastructure should be used in order to reinforce
best industry practice.
2.3.3 Construction Noise and Vibration (SEMP 003)
Potential Impacts
The construction of the Project will require the use of large mobile mechanical equipment and
processes that are likely to generate elevated levels of noise at the nearest residences. As such,
there are likely to be some significant temporary noise effects through the construction phase.
Construction noise is expected from the following activities.
• Enabling Works using heavy machinery e.g. excavators, compactors, rollers;
• Topsoil Stripping through the use of motor scrapers;
• General Earthworks (Main Alignment and Bridges) utilising heavy machinery e.g. excavators,
compactors, spreaders;
• Ground Improvements utilising vibratory construction techniques and most piling activities
using rollers/compactors and boring concrete piles.
• Bridge Construction abutment preparation using driven steel piles or auger piles.
• Installation of precast bridge structures.
• Pavement Construction where there is likely to be multiple items operating simultaneously.
Sources of vibration identified as being most likely to cause building damage are vibratory rollers
and piling. Other construction machinery and activities such as truck movements and excavators
will also produce ground vibration. Prior experience has shown that these activities can give rise to
adverse effects (particularly adverse human response).
Project-Specific Issues and Requirements
Construction noise effects are assessed in relation to the recognised construction noise standard
NZS 6803:1999, which contains recommended noise criteria that are considered appropriate and
applicable to noise from construction operations.
