CRL - Minutes – CLG Meeting – 19TH January 2016 Page 1

Minutes or Action Points General Information Delivery Work Plans (DWPs) were not circulated before the meeting – Apologies from the team. CLG members will be given 10 workings day to review the documents upon receipt.

Amendments to Traffic Plan for C2 - Alasdair Mawdsley C2 construction deck arrangements have been amended.

The original plan specifies two construction deck locations along the trench to allow construction trucks to enter and exit the site. Following further investigation, a new plan has been prepared for one long construction deck along the length of the trench.

Benefits include; - Bigger trucks - Fewer trucks - Less traffic disruption - Material can dropped off at any location within the trench - No cranes will be used to lift materials off or onto trucks - Changes to the excavation process; instead excavating in layers, it can be done from one end to the other.

Changes occur within the project footprint, so pedestrian traffic remains the same.

There will be a 10 month installation phase followed by two years of construction.

There will be a larger upfront cost, however money will be saved during construction with this new plan.

Contract 2 staff leave the meeting Erosion and Sediment Control Plan, including Chemical Treatment Management Plan – Contract 1 – Costas Chryssafis

Minutes or Action Points The purpose of this plan is to prevent sediment laden water entering the stormwater system and harbour, protect the construction zone from flooding and keep the surrounding streets clean.

A flood barrier will be installed around the Lower Queen Street excavations and a roof will cover the majority of the excavation. These structures will prevent or minimise rainfall from entering the excavation and causing damage to surrounding buildings. The flood barrier will not affect pedestrian traffic.

Piling structures and the diaphragm wall will also be used to prevent sea water from entering the site – This is noted in a separate DWP. A treatment plant will be used to treat water collected in the excavations. Storage and reuse tanks will be onsite to collect treated water forreuse in construction activities where appropriate or for discharge into the stormwater network.

If water quality does not meet the required standard, the flow to the stormwater system will be turned off and the water will be recirculated through the treatment plant again.

The treatment process will be monitored regularly.

Industrial and Trade Activities EMP – Contract 1 - Rob Van de Munchkhof The purpose of this plan is to manage the adverse effects from industrial and trade activities during construction and environmentally hazardous substances.

This plan has many similarities to the DWP from Contract 2, with the difference the use of chemicals in the bentonite treatment plant and jet grout plant.

A general Emergency Spill Response Plan has been prepared for the site.

Specific management plans will be prepared for the bentonite and jet grout plans to ensure best practice with slightly different emergency spill response procedures. Minor spillage cannot be completely eliminated so the plants will be entirely bunded.

A drainage plan prepared for the site identifies a number of catchpits required to be removed or closed off and as a precaution during the Project.

Spill kits will be located a vehicle entry points to the site with signage in place.

Stormwater monitoring will occur daily at the final discharge location.

Trigger guidelines will be reported to the council.

Construction Environmental Management Plan – Contract 1 – Rachel Purdy and Dale Burtenshaw

CRL - Minutes – CLG Meeting – 19TH January 2016 Page 3

Minutes or Action Points The CEMP is the overarching document of the DWPs and sets out the blue print of how AT and the DSBJV will comply with the designation and consent conditions.

The purpose is to avoid, remedy or mitigate adverse effects environmental, associated with construction of the project and achieve project sustainability outcomes.

There are four main stages of the Contract 1 Project.

1. Temporary accommodation and station access at the back of Britomart Station 2. CPO closure and CPO building modifications 3. Lower Queen Street piling and excavation 4. Reinstatement of Lower Queen Street,the CPO and station modifications.

Work will generally be between the hours of 7am to 7pm, however there may be some night work required on an irregular basis. This work will include bringing the piling rig into the site when roads are clear. Local residents, building managers and body corporates will be notified in advance of this work to ensure no surprises.

Next meeting There will be no CLG meeting in February or March.

From April, all members asked to pencil in the first Tuesday of every month for future CLG meetings.

Members will be advised in advance if the meeting is confirmed or not.

Comments referring to past DWPs KR – concerns about the parking/drop off bays outside 41 Albert Street revisited.

CG ensured that issues have been heard, well understood and relevant parties informed. The CRL plays a small part in the final streetscape as it is part of the wider Auckland road design plan. The final plan will not be finalised for at least another 12 months.

TC advised KR to look through the Traffic plan for Contract 2 as some questions will be answered.

DA leaves the meeting (6.45pm) KC –Before trees have to be removed from Albert Street, can they be made into an art project for students (sculpture material)/ RJ took down comment to revisit.

Next Meeting at AMP, Mairangi Room on Tuesday, 12th April 2016
