The latest ThinkBIM ‘twilight’ seminar, held in Leeds yesterday (1 June 2016), looked at the wider application of data relating to the built environment. Too many BIM events focus purely on the creation and use of data within a built asset project team; some extend the discussion to look at reuse of data for facility management, operation and maintenance; but few BIM events look at how some BIM and other built environment data might be connected to other data or even made more widely available, perhaps as open data.
Becoming more open
So far as BIM is concerned, the UK government’s 2011 insistence on BIM processes generating “open shareable asset information” is often assumed simply to be about ensuring data is interoperable: capable of being shared between different applications, operating systems and IT hardware. However, the first word is also strongly linked with the UK government’s wider digital agenda – the February 2015 Digital Built Britain strategy (strongly endorsed in the recent 2016 Government Construction Strategy and leading us towards BIM Level 3), for example, is not just about construction, but a fusion of industry strategies relating also to business and professional services, future cities and the information economy.
Discussions about open data are increasingly common, particularly in the UK, where the government has set out to be a world leader in creation and reuse of open data (it recently ranked first in an Open Data Barometer league table of international performance), with data valued as a key part of our national infrastructure (however, in December 2015, the Open Data Institute wrote an open letter to Lord Adonis, chair of the National Infrastructure Commission, arguing data is not being given “the same importance as our road, railway and energy networks were given in the industrial revolution and are still given now”).
The government’s open data push is being realised both centrally and locally, and is predicated on a belief in greater transparency, in ‘Government as a Platform’, giving tax-payers access to their data and other information derived from government investment in public services and assets. As well as central government’s National Information Infrastructure and Data.gov.uk, several local authorities have launched open initiatives, some creating dashboards sharing metrics generated from open datasets (look at the London Datastore, Open Glasgow, Leeds Data Mill, Bath:Hacked and Open Data Bristol, for example).
Open is everywhere
In addition to BIM-related open data conversations, I have attended Constructing Excellence meetings about open data (read Ben Pritchard’s blog post); I am part of an EthosVO-led, Innovate UK R&D project (SkillsPlanner) using open linked data as a resource to help address construction skills shortages; and I have led conversations in the Chartered Institute of Public Relations about the need for communicators to be more data-literate, more aware of open data issues and opportunities.
However, yesterday’s ThinkBIM event (held at AQL’s datacentre housed in a former chapel – now the beeping digital heart of Leeds) was more focused on the built environment challenges and opportunities.
- While commonly regarded as a mapping organisation, Ordnance Survey’s core skills are in data, technology and interconnections. Echoing the Association for Geographical Information’s recent Foresight report (post), Ordnance Survey’s Paul Griffiths described geospatial data as the ‘glue’ connecting data about built assets to other data about the environment and about social aspects of the areas around those built assets. in February 2015, OS launched OpenMap, a new digital map bringing open geospatial data to mobile and web platforms. Then, using examples drawn from Thames Water projects undertaken using the ‘Semantic BIM’ platform provided by SaaS vendor GroupBC (formerly better known as Business Collaborator), Griffiths showed how data about existing building types and heights, flood risks, crime, employment and education could be used to augment existing decision-making tools (“project design need no longer happen in splendid isolation”).
- ODI Leeds’ Tom Forth showed various examples of data captured by Leeds City Council and made open, including a powerful example of how public building energy use could be cross-referenced with IT data relating to office occupancy to demonstrate when and where energy savings might be made (making “ten million lines of data” open, he said, also helped make that data usable and bridged gaps that previously existed between FM and IT departmental silos). Datasets about empty buildings, housing density and open spaces could also be accessed to inform public debates about housing shortages and planning decisions.
- GroupBC’s CTO Steve Crompton then provided a ‘RetroBIM’ critique of legacy information, suggesting around 98% of current built asset data was effectively trapped in drawings and documents held in internal file-sharing systems, not lodged in databases where they could be used as a basis for decision-making (“Let’s democratise some of that data, put it in the cloud,” he said). He briefly described how GroupBC’s Semantic BIM platform could provide vital contextual data to support efficient decision-making for planning, designing, constructing and operating built assets.
During the panel discussion, it was clear security, commercial confidentiality and personal privacy concerns all need to be addressed in selecting what data might be made open (the Open Data Institute has a useful ‘data spectrum’ diagram showing the continuum from closed to open data). But Tom Forth stressed many bodies currently hold huge volumes of dormant data that could be made open (surely, such data will only have value if someone does something with it?).
Government departments are already opening up some of their data reserves so that they can be explored and exploited. In June 2015, DEFRA, one of the most data-rich departments in Whitehall, opened up thousands of datasets so that they could be more widely used to improve the quality of our natural environment.
It was also clear that the industry currently known as construction is still at an early stage in not just its BIM journey (the BIM Level 2 deadline passed less than two months ago) but also in its open data journey. To re-use an argument I’ve given in recent lectures and conference keynotes, we have only just started to move from “common paper environments” to “common data environments” – and open data is part of the more long-termBIM Level 3 picture (is it just a coincidence that the ‘semantic web’ is sometimes referred to as Web 3.0).
GroupBC: semantic BIM differentiation
I speak regularly to the main SaaS collaboration vendors active in the UK, and GroupBC is the only one actively developing semantic web capabilities. That is not to say that rivals aren’t thinking about integration between their platforms and other information systems – APIs are a key part of Viewpoint’s roadmap, I heard at last week’s customer summit, for example – but GroupBC is pioneering the use of linked data to build new products and enhance the capabilities of existing tools.
Its ‘Semantic BIM’ technology moves beyond the typical uses of BIM for visualisation, clash detection, construction sequencing, etc, and opens up a potentially huge web of related data, from ‘location intelligence’, to data shared by or licensed from other commercial or public bodies, and to data held in internal corporate systems. BIM, therefore, becomes just part of a bigger built asset data picture – the semantic web allows teams to exploit far richer seams of data, potentially unearthing vital ‘nuggets’ of information for accurate and timely decision-making.
