Mt Eden CLG meeting 11 May 2020

Agenda • Welcome • Health & safety during Alert Level 3

• Progress on site and upcoming works • Introduction to management plans • Noise and Vibration Management Plan

• Questions and feedback

Health & Safety during Alert Level 3 • New site entrance at 95 Mt Eden Road • Testing at the gate – temperature and health questionnaire

• Physical distancing on site. In cases where they’re within 2 metres, face masks are worn

• One operator per plant • Masks, sanitisers, gloves and hand wash located around the site

• PPE disposal bins around site • Break rooms designed for physical distancing • One person allowed in bathroom facilities at a time

• Staggered break times 3

North Auckland Line (NAL) Update Current priorities:

• Reschedule activities affected by lock-down to upcoming blocks of line (weekends when no trains run) • Complete installation of rail infrastructure to allow the first stage of Single Line Running (SLR) to commence in September 2020.

• Commence construction of the grade separation structure at either end of the NAL works site to allow the second stage of SLR to commence in late 2021.

• Commence utility diversions next month in areas adjacent to the rail corridor to allow retaining structures, foundations etc to be constructed.

Mt Eden Station area update Work to date:

• Building demolition almost complete (remainder of 28 Mt Eden Rd to be demolished 16/17 May)

• Completed utilities diversion for the tunnel portal

• Hoardings installed where possible. More to be installed along Ngahura, Ruru and Shaddock Sts once portal works are complete.

• Opened Flower St diversion and closed the sections of Ruru and Shaddock Sts that run through our site

• Completed portal piling platform • Completed the piles (the deepest and most technical ones) at top of portal site

• Started excavation to expose basalt for blasting • Started installing capping beam linking top of piles

Upcoming works:

• Continue portal piling • Continue excavation above basalt • Continue constructing portal structure • Utility diversions in Ruru / Shaddock Streets

• Blasting to clear basalt from June 2020 5

Overview of Main Works The Main Works comprise: • Tunnel Boring Machine (TBM) operations • Cut and cover tunnel construction • Changes to the level / grade and alignment of the existing North Auckland Line (NAL) to provide for the CRL tie-ins – requires extensive retaining • Construction of rail grade separation structures to allow for the tracks to pass under / over each other • Foundations for the new Mt Eden Station building and ventilation building – includes construction of a new CRL-line platform and redevelopment of the existing NAL-line platform • Construction of two pedestrian / cyclist bridges in the Porters Ave / Fenton St area • Installation of new track, drainage and utilities 7

East Facing Connection 1 (Khyber Pass to Normanby Road) • Trenching of existing rail corridor • Grade separation of the Normanby Rd rail crossing

• Realignment of the Normanby Road / Boston Road / Nugent Street roundabout • Diversion of utilities and construction of “temporary services” bridge (primarily provided for by the previous “Normanby Road Early Works” Outline Plan) 8

EFC 1 – Normanby Road Grade Separation

9

East Facing Connection 2 (Normanby Road to Mt Eden Road) • Trenching of existing rail corridor • Ground improvements to provide sufficient soil strength for retaining • Construction of ‘dive’ structures and rail trenches

10

Mt Eden Station Precinct • TBM operations, including spoil removal • Mt Eden Station preparatory works • reconfiguration of existing NAL platform • construction of CRL platform trench and station building (including ventilation building) foundations • Construction of cut and cover tunnels • Newton Junction Grade Separation Structure

11

West Facing Connection (Fenton/Ngahura Street to Dominion Road) • Trenching of existing rail corridor • Construction of grade separation structure

• Closure of Porters Ave rail crossing to vehicles • Construction of pedestrian / cyclist bridges at Porters Ave and Fenton Street

Construction Noise and Vibration Management Plan Construction Noise and Vibration Delivery Works Plan is a key management document.

Its objective is to use the best practicable option to avoid, remedy or mitigate adverse effects.

• Identifies exceedances (triggers site-specific plans) • Sets out what construction staff need to know • Appropriate equipment selection

• Noise barriers and enclosures • Restrictions on night-time activities • Regular communication with stakeholders

• Noise and vibration monitoring

Traffic, Access and Parking Management Plan

Mt Eden Train Station closure - Walking and cycling, bus facility improvements on New North Rd & Mt Eden Rd, New 640 bus service, more bus capacity on New North Rd.

Porters Ave rail crossing closure - Closed to vehicles. Pedestrian access maintained.

Road network improvements - New traffic signals at New North Rd/Ngahura St, Mt Eden Rd/Normanby Rd, Mt Eden Rd/Enfield St, additional lane on Boston Rd (west of roundabout).

Construction traffic activity - Avoid commuter peak hours where possible, use mainly arterial roads, over-dimension/overweight routes and motorway, manual traffic control at site access points, night works, monitoring of travel times on arterial roads

16

Traffic, Access and Parking Management Plan

Measures for Property Access

• Maintain pedestrian access to properties at all times and on-going vehicle access to properties to the greatest extent possible.

• Traffic management plans developed and consultation undertaken with impacted properties.

• Traffic controllers on site to manage construction traffic, property access and general road traffic.

Measures for Parking

• Alternative parking arrangements to be agreed where there is loss of any private parking.

17

Air Quality Management Plan

Dust emission sources • Demolition • Excavation and spoil handling • Material stockpiles • Basalt blasting and crushing • Vehicle movements

Control Measures • Wet suppression • Minimising material handling • Vehicle speed limits • Stockpile covers or wind breaks

Monitoring • • • •

Questions and feedback

22

TBM Announcement • City Rail Link’s Tunnel Boring Machine (TBM) will share the name of one of New Zealand’s most inspirational leaders, Dame Whina Cooper.

• Tunnelling tradition dictates a TBM cannot start work until it has been given a female name, a sign of good luck and safety for the project ahead. The tradition comes from the 1500s, when tunnellers, miners and people who worked underground looked to Saint Barbara, their patron saint, for protection.

• The TBM is due to arrive in kitset sections from China in October. It will be reassembled at Mt Eden project site.
