'Alice' Waterview Tunnel Project 2013

McConnell Dowell

We were contracted by McConnell Dowell to assist with the assembly of the Tunnel Boring Machine (TBM) for the Waterview Tunnel in Auckland, in 2013.

We had a substantial crew on site that were working on a shift roster around the clock, 7 days a week, 24 hours a day. Our crew were largely involved in assembling the cutting head and tail skin sections of the 14.5m diameter by 90m long TBM which involved the welding of 20mm to 90mm thick sections of the 97 piece 2200 ton machine.

We are proud to have been part of the ultimately successful ‘Alice’ TBM Project
 

Chimney Demolition 2012

Tauranga Hospital

We were engaged by BOPDHB to remove the second of the Tauranga Hospitals Boiler/Generator chimneys. After the successful removal of the concrete chimney in 2010, the focus turned to the remaining steel chimney which was 1.350m in diameter and 32m tall.  

The structural integrity of the steel was unknown, so a designed lifting sleeve was installed to each half of the chimney and attached to McLeod Cranes 170T crane with our guys working out of a man cage from McLeod’s 50T crane. The top 12m section was removed and then the remaining 20m section which penetrated the building roof by 5m, was also removed.   

The removal of the chimney made way for the second stage of the new exhaust system for the hospitals 800 Kva generator which we also installed.

Kiln Upgrade 2011

Blue Pacific Minerals

We were proud to have been involved with Blue Pacific Minerals kiln upgrade project in 2011. The project involved us manufacturing a new larger kiln to replace the existing kiln in their Tokoroa plant.

Portions of the roof were removed to allow us to install this new larger kiln in place which required precise planning as there was limited work area and no room for error.

Another successful job, due to excellent planning and teamwork.
