Developing a national 3D strategy in the Netherlands

8 December 2016 Geoff Zeiss
At the GeoBIM Building and Infrastructure Conference in Amsterdam Rob van de Velde and Friso Penninga of Geonovum presented an overview of what has been achieved to date with respect to 3D data and technology at the national level in the Netherlands and what they see as the next major step, the development of a national 3D strategy. 
 
BIM and geospatial (2D and 3D) are key underpinnings of 3D.  The Netherlands has been at the forefront of implementing BIM in the construction industry.  Just as importantly in the long term, the Netherlands has been leading the geospatial-BIM integration initiative.  It has long been recognized that geospatial/BIM integration is essential for building and infrastructure operation and maintenance or what is referred to as full-lifecycle BIM.
 
Years ago private Dutch engineering and construction companies began adopting an integrated geospatial/BIM approach to construction.  I blogged previously about a firm Royal BAM Group nv / BAM Infraconsult that adopted integrated BIM and GIS because many of its projects require full life-cycle BIM.  At the first GeoBIM conference in Amsterdam, Jothijs van Gaalen gave some real world examples of Design, Build, Finance and Maintain (DBFM) highway construction that included GIS+BIM integration. BAM’s motivation for investing in BIM+GIS are market developments especially more complex construction assignments and an increasing demand from customers for service provision throughout the entire life cycle of a project.   As another example, ARCADIS Netherlands has delivered a number of projects that integrate geospatial into the design process. 

The Netherlands has also been leading in the development and application of open BIM/geospatial standards‎ in the construction industry including NL/SfB, BS&I, ETIM, CB-NL, IMGeo, CityGML, NLCS, GB-CAS, COINS, IFC, VISI, SALES, National Model BIM Protocol, and National Model BIM Implementation Plan.  The Netherlands has created a BIM Loket (BIM Gateway) that is intended to be a national portal for information about BIM and for management of open BIM standards in the Netherlands.  It provides a central information centre for open BIM standards including related geospatial standards. 

Geospatial

Within government the Environment Planning Act is responsible for a growing focus on the physical environment.  There is also a greater desire for an integrated approach to modeling the physical environment.  Citizens are asking questions that require accurate 3D modeling, for example, noise, air quality, light and shadow, and viewports.

There have been several initiatives at the national level in the Netherlands.

  • 2010 3D pilot exploring possibilities of 3D including IMGeo and CityGML
  • 2012 3D pilot exploring Geo-BIM integration
  • 2014 “Breakthrough 3D” – application of 3D in many domains

The last “Breakthrough 3D” initiative revealed that 3D technology had matured and that there were many initiatives asking for uniform 3D data.

BIM

The Dutch Building Information Council (BIR) has been encouraging BIM for a long time – I blogged about BIR and BIM in the Netherlands previously.  One of my takeways from the recent RICS BIM conference in London was that there is a desperate need for standards, especially to classify the huge amount of date in addition to the 3D geometry that accumulates during a construction project.  Much of this data would be useful to the FM folks who are responsible for operating and maintaining the building after construction if it were accessible.

From both the perspective of geospatial data for modeling the environment and BIM data for modeling the built environment, it’s time for the next step:  a government initiative for a national 3D strategy.  The concept is to create a 3D production chain, capable of creating timely, accurate and reliable 3D geo-information.

Gap analysis – what’s available vs what’s needed

The Netherlands has a digital elevation model ( AHN or Actual Height Model) with nationwide coverage but the update cycle is on the order of eight years.  What’s needed is a nationwide point cloud that is updated at least once a year.  There are a number of ways including new technologies this could help achieve this.

3D core information GeoNovum 2016 Rob van de VeldeThe Netherlands has national 2D core data, large scale topographic data that is open and universally accessible.  It has no equivalent in 3D.  One way to generate this rapidly are reliable techniques for automating the extraction of buildings, infrastructure and natural features from point clouds.

The Netherlands has a national portal for disseminating 2D data.  The national geoportal PDOK has experienced  3-4 billion hits in 2016.  For 3D data, PDOK needs to be upgraded to be able to serve 3D data. 

 
3D standards GeoNovum 2016 Rob van de VeldeFor 3D data there are standards for exchanging 3D data about cities and BIM model such as CityGML and IFC.  What’s needed are standards for distributing and viewing 3D data.  Another important outstanding challenge is developing an interface between CityGML and IFC.

Rob emphasized that developing a national 3D standard is about identifying and involving stakeholders, understanding user requirements, and realizing the individual components, but more importantly it is about aligning individual initiatives, thus optimizing 3D supply chain.
