Long distance microtunnelling with polymer concrete

Polymer concrete (PC) products have been used for decades in the engineering, building and chemical industry. PC pipe was first developed in the late-1960s by German-based construction company, Zublin. Dr Gerhard Lang explains the benefits of using PC pipe while implementing Trenchless Technologies such as microtunnelling and pipe jacking.

Aurora Australis – the TBM putting the Bogong Hydro Power Project in lights

The fourth and final link in the scheme, the Bogong Power Development Project, to be commissioned in late 2009, will add another 140 MW to the existing 241 MW generating capacity of the Kiewa Valley Hydroelectric Scheme, making it the largest hydropower project to be constructed in Australia in 25 years. Lucy Rochlin visited the site, getting up close with the project's Tunnel Boring Machine, Aurora Australis.
