2011 in retrospect
|
2011 opened with floods threatening the underground infrastructure and construction sites in Brisbane, Australia, and closes with floods inundating large swaths of Bangkok city in Thailand and flash floods wiping out thousands of lives and the fabric of rural and village infrastructure in the Philippines. The worst of all natural disasters in the year was the earthquake and subsequent tsunami that devastated the east coast of Japan in March and led to one of the worst nuclear accidents of all time when the Fukushima Daiichi plant failed as a result. |

Norwegian expansion for BASF
|
Under an investment of almost €1 million, BASF Construction Chemicals has built a new production plant for admixtures at its factory at Granerud in Nord-Odal, Norway. The new plant will produce alkali-free accelerators to meet a strong growth in demand following launch of a new environmentally friendly alkali-free accelerator for sprayed concrete at the beginning of 2010. The investment anticipates future volume demand as well as improving BASF competitiveness in the Norwegian market and enabling a higher level of service and product availability The company will also take on more staff starting with three new employees to operate the new plant, which is to be operational in the first quarter of 2011. |

Final finish for Gotthard Baseline excavation

Some 15 years after excavations began, creation of the underground space that is the 57km long twin-tube railway passage through the base of the Gotthard Massif of the Swiss Alps is complete. On Wednesday last week (March 24, 2011), the last of more than 28 million tonne of rock was transported out from deep inside the mountain to mark the end of mammoth journey for men and machinery; for managers and politicians. |

ITA post congress analysis
|
The buzz in the corridors was positive; the talk of big projects moving ahead, immanent; progress of major projects worldwide, reported; and space for exhibitors was sold out long ago. Being at the ITA conference last week in Budapest was another exercise in asking; 'so where is this global recession?' Despite prefaces from several speakers about the dire affects of over-reactive tightening of credit by self-inflicted over-extension by banks - the need to build underground infrastructure is at record highs and now is the right time to get these projects into construction, while supply-line indices are down. Most countries in the world are programming many billions of capital investment to provide the groundwork for the cities and societies in which we will live in the near future. TunnelTalk was among the many who travelled to Budapest for the Association's 35th General Assembly, congress and exhibition, to report the major developments and topics of discussion. |

Programme challenges at Bogong
|
In the last of a series of site visit articles to McConnell Dowell projects we report on the current status of the Bogong hydropower project in Victoria, Australia. TBM excavation of the headrace tunnel and drill+blast work at the power station end is progressing towards an earlier than programmed completion. The project is supported by a legacy established back in the mid-1990s when the company achieved record setting rates on a TBM drive through the Blue Mountains near Sydney - records that still stand today. Together with the Bogong project, the company is completing the Hobson Bay sewer tunnel project in Auckland, New Zealand; recently launched an EPBM for the Rosedale undersea effluent outfall also in Auckland; and achieved industry recognition for its access tunnel and development works contract at the new Pike River coal mine on the west coast of New Zealand’s South Inland. These new projects are each contributing to the company’s expanding portfolio of experience and to establishing its reputation as a principle tunnelling contractor in the Pacific Rim region. |

Design considerations on approach to Brenner Baseline high-speed rail connection in Austria

A €2 billion, 40km section of new twin-track railway through the Lower Inn Valley towards the Austrian portals of the proposed Brenner Baseline tunnel connection to Italy, is built almost entirely underground. TunnelTalk travelled to Innsbruck to appreciate the undertaking and know how the project has influenced the criteria for design of future high-speed rail tunnels in Austria. |
