The Danish Parliament passed an act approving the construction
of a new dual track, electrified railway running from Copenhagen to Ringsted
via Køge, Denmark. Capable of handling passenger train speeds of up to 250
kilometers per hour, the new line will be Denmark’s first high speed railway,
and its largest rail project for many years. Responsibility for establishing
the 60-kilometer line, which will include four tunnels, 88 bridges, and require
the expropriation of around 290 hectares of land, fell to Banedanmark,
Denmark’s national rail owner-operator. Its stated aim was to construct the
line on time and within budget, setting a best-in-class example for all
European rail projects, in a competitive market, using state-of-the-art
technology. Construction of the new line commenced back in 2012 with completion
scheduled for late 2018.
The Banedanmark team used an extensive list of Bentley software
on the project including:
Ø ProjectWise, which helped ensure data could be
shared between all parties involved across 20 different contracts on the
project. The connected data environment provided by ProjectWise was split into
pre-tender, post-tender, and as-built information, ensuring that only the right
users had access to information relevant to their organization, contract, and
role. This well-coordinated process resulted in contract costs that were 9.3
percent lower than estimated, and an overall budget saving for Banedanmark of 10
to 15 percent.
Ø MicroStation, chosen to ensure that all
project information could be visualized within a comprehensive modeling
environment. The flexibility offered by the DGN format and tools within
MicroStation made it possible for the team to combine data generated using
Bentley applications and third-party software for tasks including consistency
and clash control, creation of multi-discipline sections or hypermodels,
quantity takeoffs, quality checks, and high resolution visualizations and animations.
Ø Bentley Rail Track, used to create 3D models
of the minimum infrastructure gauge. Built-in Danish design standards and
validation enabled Banedanmark to create models and animations approximately 10
times faster than using other techniques.
Ø PowerCivil for Sweden, which enable the team
to easily extract earthworks volumes. The 3D models were then used by the
contractors for machine control, increasing the accuracy and speed of works.
Finally, mapping functionality within PowerCivil for Sweden made it possible to
exchange data with ArcGIS, Banedanmark’s GIS in operations and maintenance.
As a result of its achievements on the Copenhagen – Ringsted
project, Banedanmark implemented a strategic project called The Digital Railway
of Future. The project’s mission is to look at implementing the same methods
and requirements on all construction projects in the future, and to explore the
potential for using models and intelligent data generated during design and
construction within asset management, implementing a whole lifecycle approach
to BIM.
Gita Mohshizadeh, CAD manager, Banedanmark, said, “Bentley’s
commitment to providing the tools necessary to support the whole lifecycle of
assets and interoperability with other design and construction software means
that Banedanmark’s project information is usable, well-coordinated, and
well-documented.”
