Automated One-Call system in the Netherlands for excavation damage prevention
I have blogged
numerous times about the challenge of accurately geolocating underground
utilties. Most recently I blogged about the estimated ROI for
investment in improving the geolocation and other information about
underground utilities and the remarkable project of the City of Las
Vegas to create a 3D model of its underground utilities.
One-Call in the Netherlands (KLIC)
Yesterday at the INSPIRE conference in Florence, Ad van Houtum of the Dutch
Kadaster described how the Netherlands is addressing this challenge. The
Netherlands has had what in North America is called a One-Call or Call-Before-You-Dig system since 1967. The objective of the system is to
prevent damages to the utility network and to ensure the safety of excavators during excavations.
From 1967 to
2010 The Netherlands had a manual One Call System (KLIC) that worked similarly to North American One-Call systems. Anyone planning an
excavation would call the One-Call telephone number and communicate the
location, duration, and other information about the planned excavation.
The One-Call center would contact the relevant utilities (network
operators) who would then send maps of their network infrastructure to
the excavator. (In North America the utilities would more typically send
vans and staff with equipment to try to locate underground facilities.)
The Dutch service was free of charge for excavators and funded by the
network operators. It generally took about three working days to provide
the required information to the excavator.
2010 the Netherlands switched to a digital information system
(KLIC-Online) that worked in a similar way except that everything could
be done online. With KLIC the turnaround time was reduced to hours.
Both the manual and KLIC-Online One-Call systems were voluntary until 2008 when
a law was passed which made KLIC mandatory for both network operators
and excavators with severe penalties for excavators who circumvented the
system. There is also a charge of € 29.50 for every excavation
The Netherlands is now planning the
next version called KLIC 2020. The business drivers for the next version
is to further reduce the number of incidents of excavation damage,
improve the efficiency of both network operators and excavators, and to
make the information available to other domains such as planning and
zoning and public security.
The industry wants the system
to be available 24x7, near real-time, and should include other
information in addition to network infrastructure such as soil types,
ground water, parcel file, and so on.
It also should have a secure
authentication and authorization service. It is planned that the view
service will be based on the OGC WMS standard, and the download service
INSPIRE and KLIC 2020
III Theme 6a Utility Services (INSPIRE US) is the relevant INSPIRE standard.
All government agencies are required to adhere to this standard. This
includes 80 % of the network operators in the Netherlands.
this context the KLIC 2020 system will be INSPIRE US compliant, with
24x7 availability, 99% up time, supporting more than 20 simultaneous
users with a better than 5 second response time for viewing and better
than 20 seconds to begin downloads.
