Hobson Bay Tunnel Project, New Zealand

Watercare Services awarded McConnell Dowell, in joint venture, the construction of the Hobson Bay Tunnel Project located in Auckland, New Zealand. The project was to replace a 90 year old sewage pipe that crosses the Bay, on Auckland's waterfront Tamaki Drive. The tunnel offers greater sewerage capacity to cater for projected population growth in the area and prevents wastewater overflows into both the Bay and Waitemata Harbour basin. The replacement of the existing wastewater pipe also opens up the Bay for recreational boating. The project scope consists of a 3 km long, 3.8 m internal diameter tunnel which is driven approximately 30 m below the bay floor; construction of three shafts of approximately 35 m to 40 m in depth (23 m, 8 m & 10 m internal diameters); surface reticulation/connection works; and demolition of the existing sewer pipeline that crosses the Bay. This project uses a Tunnel Boring Machine by Lovat of Canada, and construction techniques are designed for a combined firm rock and soft substrate. The 23 m diameter shaft includes considerable mechanical and electrical works (the supply and installation of six 1MVA pumps), while all three shafts also require a significant amount of concrete works. McConnell Dowell has worked closely with Watercare Services to develop a stakeholder management plan to ensure bay users were not impacted during the construction of the new tunnel - especially during the demolition of the existing sewer line.

"Wild Encounters" Ljohnston325's photos about Kaikoura, New Zealand

A TripAdvisor™ TripWow slideshow of a travel blog to Kaikoura, New Zealand by TravelPod blogger Ljohnston325 titled "Wild Encounters" Ljohnston325's travel blog entry: "What an exciting Dec 26 & 27! I've seen seals & swam with dolphins - SO cool! We saw the seals various times on our rainy drive into Kaikoura on Dec 26 (check out the pics of our rained-in lunch on the bus!), which was sweet, especially since our whale watch was cancelled due to the weather. We hit a winery instead - a very **** winery - but it killed the afternoon in any case. Next morning we were up before the sun - but the sun did come out! We had our dolphin swim that morning, so awesome. There was a pod of about 500 dolphins for us to swim with and they came SO close to you! It was actually our job to entertain them so they'd stay around us. We followed the pod, getting in & out of the freezing pacific about five times (well, they did - I stayed on board after the first & took photos. I couldn't handle all the pressure of the wet suit, deep ocean, etc, but I still had a ball!). I even saw TWO ALBATROS! They were amazing - so big, it was nuts! I couldn't believe I actually saw them in the wild! Kaikoura is famous for their marine life, though, because of the structure of the base of the ocean (a very deep cliff not too far off shore which results in currents which results in heaps of marine life), but I didn't think it would be this close to us. And I'm still having trouble believing that I swam in the ...
