The Commonwealth Government has launched the National Map Open Data initiative http://nationalmap.nicta.com.au describing it as part of the Government’s commitment to increasing the number of publicly available datasets.
Many of the world’s worst accidents are not the result of a single major failure, human or mechanical; one that perhaps should and could have been anticipated and prevented. Instead they result from an unfortunate concatenation of minor failings, each of little consequence when taken in isolation.
Taiwan's second largest city, Kaohsiung, suffered a series of catastrophic explosions on the night of 31 July resulting from gas leaking from an underground pipeline. The explosion following the initial leak fractured other pipelines precipitating additional fires and explosions. Initial reports put the number of dead at 25 and those injured at 257.
In September 2012, Ireland’s government-owned electricity transmission system operator, EirGrid, opened the high-voltage direct current submarine and underground power cable which links the electricity transmission grids of Ireland and Great Britain known as the East West Interconnector (EWIC). It has a power rating of 500 MW and is one of the largest High Voltage Direct Current schemes in the world to use Voltage Source Converter technology.
The advents of summer and improvements in the US economy have been blamed for a record number of calls to Indiana's dial-before-you dig-service.
In the ever-growing catalogue of excavation accidents this was a biggie: one dead, six injured and, most spectacularly, one home totally destroyed, 20 left uninhabitable and another 34 damaged, according to press reports
There's a depressingly long list of accidents, many fatal, resulting from contractors puncturing buried gas pipes after failing to properly locate them prior to excavating, but what about a fatal gas explosion during excavations without any gas pipe being ruptured? That’s what happened in New Zealand.
We’ve written often in this column about the dangers associated with excavations and the catastrophes that have often fatally demonstrated those dangers. In most cases they are the result of the excavators, for whatever reason, not having accurate information about the location and nature of underground infrastructure. However, above ground infrastructure that is in plain sight has on more than one occasion proved fatal to those digging up the ground beneath it.
Global recruitment firm Harvey Nash has released the results of its latest annual CIO survey saying it “points to a positive sense of expectation about new opportunities that lie ahead.”
The state government of New South Wales, Australia has tapped the power of Google Earth to make spatial information about the state - maps, land parcels details, survey information, census data and much more readily accessible in a visually appealing way.
In the ever-growing catalogue of excavation accidents this was a biggie: one dead, six injured and, most spectacularly, one home totally destroyed, 20 left uninhabitable and another 34 damaged, according to press reports.
Hunter Water, the water authority in the Hunter Valley region of NSW, has used horizontal directional drilling technology to create a 4.5km tunnel to upgrade its wastewater network. The tunnel is its longest ever using horizontal drilling technology. It could also be close to a world record.
Brigham McCown, a former head of the US federal agency responsible for overseeing the transportation of hazardous materials by air, land, sea, rail and pipelines, wasn't mincing words in this opinion piece in Forbes Magazine, in February.
The Productivity Commission is investigating investment in Australia's public infrastructure. It has been told that open access to government and industry data will be ‘transformational’ for major infrastructure projects.
There’s a whole range of technologies available for locating underground infrastructure and, in Australia, a structure for gaining and demonstrating competence in their use.
In 1985 the US Government’s Occupational Safety & Health Administration (OSHA) initiated a Special Emphasis Program covering trenching and excavation. Announcing the move, is that “Because of the continuing incidence of trench/excavation collapses and accompanying loss of life, the agency has determined that an increased OSHA enforcement presence at worksites where such operations are being conducted is warranted.”
Closed circuit television (CCTV) is an extremely useful technology for inspecting the condition of pipelines and conduits - from the inside. Trenchless Australia has produced a handy guide to the technology and its use.
Training.gov.au has released a new version of its training requirements for competency in trenching, the second in six months. Any organisation seeking to get its workers trained to the new competency requirement might struggle: courses specific to it seem to be in short supply.
Perth based Trenchless Utilities claims to have invented a new technology for trenchless installation of pipes and cables that is ideal for use in narrow corridors thanks to its small footprint.
Whatever your interest you’ll find no end of videos on YouTube to feed it. Much of the footage is for amusement only but there’s also plenty of serious stuff on serious topics: and digging trenches is no exception.
If you think a sterile strip is bit of sticking plaster that you slap on your skin after losing an argument with a sharp object, think again. In the UK at least a sterile strip is the land on either side of buried pipelines or other underground infrastructure to which regulations apply that are designed to protect the infrastructure and the rights of its owners and operators.
