Preparing Austroads' Asset Data Standard for BIM
29 March 2018
Austroads:
Austroads has published a report that compares
the Austroads Data Standard with
buildingSMARTS’s IFC4 and Uniclass
2015. All are works in progress.
This report is a study of certain aspects of Austroads Data Standard for
Road Management and Investment in Australia and New Zealand: Draft 2
Version 2 (due to be published in the first half of 2018).
The study found that the structure and content of the Data Standard can
be improved to better serve
road networks through the asset lifecycle,
and to align with data standards for
rail,
water and other transport networks.
The Data Specifications Inventory of 32 object classes within Austroads’
draft standard has been mapped as far as possible to buildingSMART’s
IFC4 Add2 and to the UK Government’s Uniclass 2015. This reveals gaps
and inconsistencies in all three documents, which need to be addressed
as roads infrastructure asset management, across the asset lifecycle,
moves towards adoption of
Building Information Modelling (BIM).
The developers of buildingSMART have begun work on ‘open’ modelling
requirements for road and rail networks, and for their components (e.g.
bridges) but it will be some years before this is published and
implemented by software vendors such as Autodesk.
Uniclass 2015 is intended to be a single dynamic classification system
for BIM projects, serving all sectors and disciplines equally, and the
complete asset lifecycle. It already contains many infrastructure
objects, and more are being added regularly. However it does not yet
include a Properties table.
It is expected that all three initiatives will converge over the next
few years, fully enabling the modelling of transport (and other)
infrastructure, as well as of buildings and landscapes. The developers
of each should plan for this convergence.
The report recommends that Austroads revises its Data Standard, and
contributes to the development of IFC Infrastructure (which is
developing more physical objects in the realm of infrastructure), and of
Uniclass 2015 (which does not yet include a Properties table).
