Lynne and Shelley talk to Christian Renewal School and Sancta Maria Catholic School during today's audioconference. Image: LEARNZ.

Come and meet Dennis, the huge, yellow gantry crane. What does Dennis do? Image: LEARNZ.

Dennis moves across these runway beams to place the concrete beams that support the bridge deck. Image: LEARNZ.

Dennis runs on electricity. Can you see the green generator on the top of the crane? Image: LEARNZ.

James is a Section Engineer. He showed Shelley how Dennis works high above the motorway. Image: LEARNZ.

You can see Dennis in position above the motorway. Dennis can lift and place beams. Image: LEARNZ.

Dave Young talks to Shelley about safety while working at heights. What do you think Dave is holding? Image: LEARNZ.

Shelley and Alvin beside the construction of the Great North Road Interchange. Image: LEARNZ.

Lynne and Shelley talk to Avondale Intermediate and Westmere School during the audioconference this morning. Image: LEARNZ.

You can see a line of columns with cross-heads at the top, these will support a ramp on the GNRI. Image: LEARNZ.

A crane delivers steel to help construct the cross-head. Why is steel needed? Image: LEARNZ.

Alison explains to Shelley how columns and cross-heads are constructed. Image: LEARNZ.

You can see all the steel needed to reinforce the concrete that will make up the cross-head. Image: LEARNZ.

Alison stands inside the casing used to pour concrete into to form a column. Image: LEARNZ.

You can see the concrete beams that support the road deck. Image: LEARNZ.

Looking out across part of the Great North Road Interchange construction site. What do you think some of the challenges of working above a busy motorway are? Image: LEARNZ.

This area is a protected historical site that people will be able to access after the Waterview Connection is completed. What artefacts have been found here? Image: LEARNZ.

Leon Field shows you an old vase that was found on the construction site; where do you think it came from? Image: LEARNZ.

Lynne and Shelley talk to Owairaka School and Avondale Intermediate School during the formal audioconference this morning. Image: LEARNZ.

Alice the Tunnel Boring Machine has completed the first tunnel and is over half way through finishing the second tunnel. Why do you think there are two tunnels? Image: LEARNZ.

Warwick uses a model to show how Alice was turned around to start the second tunnel. Image: LEARNZ.

Concrete segments are taken into the tunnel. These segments will line the tunnel. How are the segments put into place? Image: LEARNZ.

This area of trees has been protected as it is a rare volcanic rock forest. Water is treated before it leaves the site to protect this creek. Image: LEARNZ.

Rachel demonstrates how water is treated to remove sediment and then tested to make sure it has a safe pH (acidity). Different chemicals can be added to help sediments settle out and to reduce the pH. How is pH measured? Image: LEARNZ.

Rachel shows Shelley a noise wall that helps reduce the noise of construction for people living near by. Image: LEARNZ.

Ben shows a model of a machine used to build roads. Image: LEARNZ.

Shelley overlooks the Northern Approach Trench. How is this end of the tunnels different to the other end? Image: LEARNZ.

Paul shows you part of a water feature that is being built in the Waterview playground. Image: LEARNZ.

Looking north towards Dunedin City. Can you see Otago Harbour? Image: LEARNZ.

To the west you could see Lake Mahinerangi before the cloud obscured the view. Image: LEARNZ.

Cloud covered much of the country so there wasn't much to see during your flight to Auckland. Image: LEARNZ.

Shelley and Alvin the LEARNZ ambassador wait for their luggage at Auckland airport. Image: LEARNZ.

You could see construction of one of the ramps as you passed by the Great North Road Interchange. Image: LEARNZ.

Dave Young takes Shelley through a safety induction at the northern site office. What do you think you would need to do to stay safe on the Waterview Connection construction site? Image: LEARNZ.

Alvin checks out the golden rules of safety on the Waterview Connection construction site. Image: LEARNZ.
