Towards a uniform quality of sub-surface utility infrastructure locational data

摘要

It is a fact that the available sub-surface space is quickly filling up and that the risk of damage to infrastructure and the environment is increasing steadily.On the other hand,a large number of technological advancements have greatly improved the quality of the implementation and management of underground pipeline and cable assets.These advancements not only span equipment to install pipelines,ducts and cables,but also the GIS technology,sub-surface locating systems and other georeferencing technologies give the user more information to base a decision on.But is more information also better information or is it a false sense of security?As I have experienced worldwide,the latter is often true because most asset managers‘do their own thing'.So who can and should take action in the chain op sub-surface pipeline and cable installation,maintenance and management to evolve towards a uniform quality of asset data?This presentation will assess the each stakeholder's role and responsibility in the chain and suggest a possible solution towards creating a uniform quality of data over the next couple of decades.
