5.2. Noise and Vibration Monitoring
Noise monitoring has been undertaken for new plant and activities since commencement of construction in
January 2012 to assess levels against noise predictions (as per the Construction Noise and Vibration
Management Plan) and confirm compliance with the project noise criteria, specifically as relates to Consent
conditions CNV.2 for noise, CNV.3 for noise from air blast and CNV.4 and CNV.5 for vibration.
No blasting was carried out during August. The focus for noise and vibration during August has been
assessment of extended works required outside normal working hours (07.30 – 18.00hrs Monday to
Saturdays) and submission of Site Specific Noise management Plans (SSNMPs) to Council.This was
particularly in relation to service works at Great North Road Interchange (GNRI) and day-time sheet piling
works for the tunnel spoil handling building. Noise monitoring was undertaken for the sheet piling works
which informed SSNMP#37. The table below shows the maximum measured noise levels, which confirmed
the need for a SSNMP in relation to sheet piling works. Sheet piling was stopped 27/08/13 following nosie
monitoring and trials undertaken to assess the most appropriate mitigation measures and a SSNMP
submitted to Council for approval.

5.3. Air Quality Monitoring
Two Total Suspended Particulate (TSP) analysers and one met mast are required in the Southern Area
(Sector 9) and one TSP analyser with met mast is required in the Northern Portal Area (sector 7) under
consent conditions AQ16 and AQ17.
Two E-BAM TSP monitors (E-BAM1 & EBAM2) are located in the Southern Area. Up until 29th August
EBAM1 & EBAM2 were co-located on site adjacent 123 Hendon Avenue. EBAM2 was relocated near to
the Southern Approach Trench on the 29th August, on site at the rear of 91 Hendon Avenue. The Northern
Portal area E-BAM is located outside the Waterview School grounds.
E-BAM results for August show levels below the project consent limit for TSP with the exception of the
following episodes.
Southern Area (EBAMs 1 &2):
Exceedences of the hourly trigger level of 200 µg/m3 occurred at EBAM1 (22/08/13 07:00am-
08:00am 561 µg/m3; 24/08/13 09:00pm-10:00pm 443 µg/m3). These exceedances can be
attributed to high humidity events caused by rainfall. Data at the co-located EBAM2 showed
concentrations well below the trigger level (22/08/13 07:00am-08:00am 16 µg/m3; 24/08/13
09:00pm-10:00pm 19 µg/m3). It should also be noted that the exceedances also occur outside of
construction hours.
No exceedences were recorded of the daily average consent limit of 80 µg/m3 for EBAM1 &
EBAM2.
No exceedences were recorded of the hourly trigger level of 200 µg/m3 for EBAM2.
Northern Area (EBAM 3):
No exceedences were recorded of the hourly trigger level of 200 µg/m3
No exceedences were recorded of the daily average consent limit of 80 µg/m3.

5.4. Ground Water Monitoring
Monthly monitoring for piezometers identified in Appendix A of the Groundwater Management Plan
(GWMP) is ongoing; with the exception of around 3 piezometers around the tunnel which are still to be
installed (these piezometers are located in the Unitec grounds and will be installed, where landowner
approvals allow 12 months ahead of active tunnelling as per the rev 4 GWMP).
Piezometers located within 150 m of the Southern Approach trench have been monitored weekly since
June 2012 in advance of excavation that commenced in July 2012. Dewatering activities commenced in
September 2012 when groundwater was encountered in the excavation at a depth of approximately 9 m
below ground level.
The southern approach trench extends from approximate CH10530 (to the south) to the southern portal
head wall at CH11080. Over this length the excavation has reached full depth and the base slab has been
poured. Dewatering via sump pumps in the excavation and below the base slab is occurring between
chainages 10600 and 11080. Accordingly groundwater levels in piezometers within 150 m of the Southern
Approach Trench are monitored twice-weekly in accordance with condition G.6.
CH11000 to CH11080
Piezometers in very close proximity to the trench (i.e. less than 50 m distance, and inside the construction
zone) have recorded a drop in groundwater level of up to 18.5 m in the East Coast Bays Formation (ECBF),
6.8 m in the Tauranga Group alluvium and up to 5 m in the basalt (Figure 1). Drawdown in the basalt and
alluvium reached near steady state conditions in March / April 2013, and in most piezometers the
groundwater level rose in mid-April and remained steady as a result of normal to above normal rainfall
through to the end of June. A slight drop was observed in July (generally of less than 0.5 m) as a result of
low rainfall (33% of normal, Figure 2) however water levels have tended to recover slightly through
August as a result of rainfall recharge.
Drawdown in the ECBF appears to have reached a pseudo-steady state (excluding seasonal fluctuations)
now that excavation has reached maximum depth. As the base slab is drained we do not expect to see
August 2013 Environmental Report
AC Monthly Report August 2013 final.docx Page 8 30 September 2013
any recovery of these water levels; however as maximum depth has been reached we do not expect that
there will be any further significant drawdown.
Beyond the construction zone (> 50 m distance) piezometers in this areas have recorded a drop in
groundwater level of up to 4 m in the basalt and alluvium, and up to 6 m in the ECBF. Nine (9)
piezometers have recorded a groundwater level below alert trigger level. Several of the affected
piezometers (BH519, BH1106, BH1108 and SPZ005) are located along the axis (and deepest part) of the
basalt lobe that is intersected by the Southern Approach Trench excavation. The zone of greater
drawdown along this axis likely reflects a fracture, of low storativity, that runs through the middle of the
basalt lobe. As outlined in previous reports there is 8 m to 20 m of incompressible basalt in this area so
the potential for damaging consolidation settlement is considered to be very low. An alarm trigger level
for bores in this area was recommended (December 2012) to be 8 m (i.e. allowing sufficient time to warn
against drawdown approaching that which might result in settlement exceeding the consented levels);
groundwater levels at the end of July remain well above this level. As with those piezometers in close to
the excavation, we are not anticipating any further drawdown in the groundwater level at these
locations.
Figure 1: Drawdown vs. Distance Graph for SAT (to August 2013)
The other affected piezometers (BH503, BH525, DH825, DH826 and DH829) are clustered around the
Southern portal head wall. Within these piezometers only the groundwater level within the ECBF is
below an alert level. Groundwater levels in the basalt and alluvium remain above trigger levels and have
been steady or rising since April 2013; hence the potential for damaging consolidation settlement is
considered to be very low.
In light of the alert level exceedances we have increased the number and extent of wells being monitored
twice-weekly (the majority of which are continuously logged) and groundwater level data will continue to
be reviewed every other day until the pressure has fully stabilised. In addition we are currently reviewing
the groundwater level and settlement predictions for this area to confirm that there is no increase in the
potential for effects resulting from this drawdown.

Markers within 100 m of the area (generally located on control sections K, L and M) have been specifically
reviewed, with movement being within the trigger levels for these areas.
CH10500 to CH11000
Within this zone excavation has reached maximum depth and groundwater levels in all piezometers have
been steady or rising since the end of March 2013. Groundwater levels in this area are all above trigger
levels.
Seasonal Trends
Monitoring confirms that recorded drawdowns continue to be exacerbated by the exceptionally low
rainfall that fell in Auckland in January, February, March, and again in July. Total rainfall for the Jan to
March period was less than 30 % of normal rainfall, and during the month of January less than 10 % of
normal rainfall was recorded. This followed a dry period between September 2012 and December 2012;
during this time although total rainfall was 50 % to 80% of normal, most of the rain fell in discrete storm
events therefore it can be expected that a significant proportion of the rain would have discharged to
stormwater without recharging the aquifers.
Rainfall in April, May and June 2013 has been above normal (around 600 mm over these months
compared to an expected norm of around 350 mm). More than 60 % of piezometers around the SAT have
recorded a trend in rising groundwater levels since April 16th when the first significant rainfall of the year
fell (see example of BH1106, Figure 2 below). This trend is also seen in monitoring of piezometers in the
wider Project area. The rise is generally of the order of 0.5 m to 2.0 m (since mid-April) however in some
areas the groundwater level has risen by more than 3.0 m.
Figure 2: Groundwater Levels in BH1106 compared to daily rainfall
Rainfall in July was 33 % of normal resulting in a drop in water level of typically between 0.1 m and 0.5 m
in all piezometers in the Southern Area (see example in Figure 2). Following above average rainfall in
August there has been a rise in groundwater levels.

5.5. Oakley Creek Flow Monitoring
Six (6) continuous flow monitoring stations have been established by NIWA in Oakley Creek. The data
from these are updated and reviewed on a monthly basis to investigate whether the construction works
have had any effect on base flows in Oakley Creek. Five gauges were installed in late 2010, with the sixth
(Cradock Street footbridge) installed in September 2009.
Comparison of records for April to August 2013 show recorded flows generally increasing at gauges the
further downstream, from the sewer bridge to Waterview Downs. This is consistent with increasing
contribution from the aquifer and increasing catchment moving downstream.
The next full review of creek flows will in reported in the September 2013 report.
5.6. Settlement Monitoring
Monthly monitoring of framework ground settlement markers identified in the Settlement Effects
Management Plan (SEMP rev3), and additional markers installed since that time continues.
Framework markers within 150 m of the Southern Approach Trench have been being monitored
weekly since June 2012 (Figure 5). Surveyed ground levels have generally shown a broad upward trend
(around 3 mm to 5 mm) since the end of March in response to rainfall and seasonal swelling.
The majority of markers continue to show movement within +/- 3 mm of their adopted pre-construction
minimum (i.e. within the accuracy of the survey). Six markers (M9, X12, X17, X23a, Z154 and Z155)
continue to show movement in the range of 4 mm to 10 mm however this level of movement is still
within adopted trigger levels. There is no clear spatial distribution (there are markers between these six
localities and the alignment which have shown negligible movement) and with exception of X17 all
markers have shown an upward trend since June, suggesting that the movement is likely to be as a result
of seasonal settlement and rebound.
Figure 3: Ground movement for markers within 150 m of the Southern Approach Trench (to July 2013)
August 2013 Environmental Report
AC Monthly Report August 2013 final.docx Page 11 30 September 2013
For two marks (Z154 and Z155) downward movements of up to 10 mm were recorded in June and early
July approaching the alert trigger level of 10 mm at this location. These markers have shown recovery of 3
mm to 5 mm since that time, consistent with markers in the wider area. These markers form a differential
pair (in accordance with condition S.17); differential settlement between the two markers is calculated to
be flatter than 1/6,000 therefore the potential for any adverse effects is considered to be negligible and
all other markers in this area have indicated movement of less than 3 mm to 5 mm (well within trigger
levels). Regardless we will continue to monitor these markers.
Differential movement between markers is flatter than 1 in 7000 in all other areas and remains well
below trigger levels, as are assessed building damage categories in the area. Markers will continue to be
monitored and reviewed weekly.
The Alliance has recently installed 7 No. fixed deep survey benchmarks to supplement the 2nd order LINZ
benchmarks to which this survey data has historically been tied. The LINZ benchmarks are shallow and
likely to have been moving seasonally and therefore the seasonal range may have been underestimated.
Once the benchmarks have been fully established and incorporated into the survey loops, the Alliance will
be reviewing the seasonal range of movement around the Northern Area and tunnels. This will be
presented in the updated SEMP.
5.7. Ecological, Water Quality Monitoring & Sediment Quality Monitoring: Oakley Creek
Construction phase water quality monitoring has been carried out monthly, as required by consent
conditions, with the most recent routine monitoring carried out on 16 August 2013. Pre-construction and
construction phase monitoring results are shown in Figures 4 to 9 below. Full laboratory transcripts are
available on request.

The August routine monitoring data are summarised as follows:
Turbidity and suspended solids results were comparable to July results and to baseline data
collected prior to the commencement of construction.
pH was near-neutral at all sites and well within the accepted range that is representative of good
water quality (pH 6-9).
There were no significant differences in metals concentrations upstream and downstream of the
construction site, and measured metal levels downstream of the site were within the ‘baselind’
range recorded before the commencement of construction.
An incident involving the accidental discharge of water from the stormwater pond near CY11 occurred on
the night of 17/18 July. The results of initial follow-up water quality and ecological monitoring were
reported to Council in early August, and further follow up monitoring has recently been completed and
reported to Council.
August 2013 Environmental Report
AC Monthly Report August 2013 final.docx Page 14 30 September 2013
Six-monthly aquatic ecology and stream channel monitoring will take place in September, ahead of the
commencement of the 2013-2014 earthworks season.
Fortnightly monitoring of significant vegetation, including geraniums, continues to be carried out. All
translocation of geranium plants from areas that will be affected by the works has been completed. This
has included successful transplanting into the Diversion C area. The annual lizard and geranium
relocation report will be issued to Counil before the end of September.
A New Zealand dotterel in breeding plumage has been observed at the Great North Road interchange
(‘teardrop’ area). Measures had previously been taken to discourage dotterels from nesting in this area
(e.g. letting grass grow rank), and it does not appear that this dotterel has attempted to build a nest here.
The area is being monitored every few days, ascertain if the situation changes.
5.8. Contaminated Soil Monitoring
5.8.1. Site monitoring
No unexpected contamination was reported during the month of August 2013.
5.8.2. Soil disposal
Tables 5.1 and 5.2 below provide a summary of the soil volumes removed from the project area in August.
A total of approximately 36,350 tonnes of soil and rock were removed from the project that month. All
rock was excavated from the southern area of the project and was removed to Wiri Cleanfill for processing.
Soil was removed to Onehunga Foreshore, Ridge Road Landfill and Wire Cleanfill during the month of
August. The soil removed to Onehunga Foreshore and Wiri Cleanfill comprised East Coast Bays Formation
soils from both the northern and southern portal trench excavations. Soil removed to Ridge Road Landfill
comprised excavations related to the near surface soils from establishment works in the north and south of
the project and piling works from the GNRI works.
Earthworks that will require contaminated soil monitoring and off-site disposal in September are
summarised below.
• Between Maioro Interchange and Richardson Road for motorway alignment and retaining wall
construction to Wiri cleanfill/Onehunga Foreshore Project (up to September 2013).
• CY9, CY10 and CY11 (spoil building) formation works for disposal to both Wiri cleanfill, Three Kings
Managed Fill and/or Ridge Road Landfill (up to September 2013).
Works within Southern Approach Trench for disposal to Wiri cleanfill/Onehunga Foreshore Project (up
to September 2013).
Northern portal trench excavation for disposal to Wiri Cleanfill (up to 2014).
Establishment works, utility diversion and and piling works for the GNRI works for disposal to either
Wiri cleanfill, Three Kings Managed Fill, Ridge Road, Greenmount Landfill and/or Redvale Landfill (up
to 2014).

General Communications Activity: Overview
Following the excitement and activity around the TBM arrival in July, August has been a month of consolidation, future planning and social media interaction.
We have been refining the communications strategy for tunnelling – in particular how we engage residents above or directly adjacent to the tunnel alignment. Residents will be initially engaged ahead of the TBM launch to allay any concerns they may have, and then kept up to date with progress at a level they’re comfortable with through direct access to the community liaison team. General tunnelling progress will be shown online through a progress graphic.
We’ve also been working closely with the NZTA’s acoustic and environmental teams to clarify the short- and long-term consent conditions pertaining to construction and operational noise. This has in turn enabled us to ensure residents better understand the full picture of what lies ahead. Other NZTA engagement has been through a Western Ring Route coordination group to look at creating a more streamlined customer experience for SH16 users through construction.
This month we have adopted the cancer society as a nominated charity to support. We will be using our existing communications channels to help spread awareness of treatment and support in the communities in which we work, and have also commissioned the painting yellow of the launching gantry to be used for the Great North Road Interchange to assist the overall promotion.
The majority of our communictaions activity through August has been in the social media space. We now have over 900 ‘likes’ of our facebook page, and note that posts generally reach an audience of 2000+. Time-lapse and progress videos on YouTube are being well received, with social media activity well supported by traditional media interaction.
Summary of external communications activity:
Media release on main drive lowering
Time-lapse progress video released
Social media updates through facebook, Twitter and YouTube
The next major communictaions milestone will be the public open day on October 13.
