IFC for LARK – Tidligere arbeider

En sentral rapport utarbeidet i 2009 viser at man tidligere har jobbet med å se om Landskap kan innarbeides i IFC og hvilke muligheter dette vil gi. I dag tre år senere har teknologien forbedret seg, flere prosjekteksempler støtter opp under dette og det er jobbet frem flere akademiske rapporter omkring BIM for Landskap.

A central rapport, published in 2009, shows that there has been earlier work on integrating landscape in the IFC standard and the possibilities of this development. Today, six years later, the technology has improved, more project examples are supporting its cause, and several academic reports on BIM for landscape have surfaced.

IFC for Lark - Interoperable Standards Development


Forord fra rapporten:
Preface from the report:

Since 1995 the buildingSMART International Alliance for Interoperability (buildingSMART)
has developed a robust standard called the Industry Foundation Classes (IFC). IFC is an object oriented data model with related file format that has facilitated the efficient exchange of data in the development of building information models (BIM).
The Cooperative Research Centre for Construction Innovation has contributed to the international effort in the development of the IFC standard and specifically the reinforced concrete part of the latest IFC 2×3 release. Industry Foundation Classes have been endorsed by the International Standards Organisation as a Publicly Available Specification (PAS) under the ISO label ISO/PAS 16739. For more details, go to http://www.tc184-sc4.org/About_TC184-SC4/About_SC4_Standards/
The current IFC model covers the building itself to a useful level of detail. The next stage of development for the IFC standard is where the building meets the ground (terrain) and with civil and external works like pavements, retaining walls, bridges, tunnels etc. With the current focus in Australia on infrastructure projects over the next 20 years a logical extension to this standard was in the area of site and civil works.
This proposal recognises that there is an existing body of work on the specification of road representation data. In particular, LandXML is recognised as also is TransXML in the broader context of transportation and CityGML in the common interfacing of city maps, buildings and roads. Examination of interfaces between IFC and these specifications is therefore within the scope of this project. That such interfaces can be developed has already been demonstrated in principle within the IFC for Geographic Information Systems (GIS) project.
National road standards that are already in use should be carefully analysed and contacts established in order to gain from this knowledge. The Object Catalogue for the Road Transport Sector (OKSTRA) should be noted as an example.
It is also noted that buildingSMART Norway has submitted a proposal for an “IFC for Roads” project. This project will collaborate closely with developments in this area and ensure that the resulting definitions match Australian practice.
