CIBSE SEMINAR BUILDING INFORMATION MODELLING
who has rights to, and ownership of, the data. A properly developed BIM implementation plan is essential, he said. Reminding the audience that typically
80% of a building’s cost is in its operation, George Adams of Spie Matthew Hall, CIBSE president-elect, was clear where he saw the real benefits of BIM as he posed the question: ‘What facilities manager (FM) would turn down a chance to get hold of a BIM model?’ By integrating BIM with FM solutions,
there were previously unattainable opportunities to produce accessible and truly useful owners’ manuals, to enhance preventative maintenance and enable re- commissioning, he added. He saw that there were challenges in integrating some of the true value of BIM in current standard plans of work, as they typically included cursory mention of the maintenance needs of a building. Architect Mike Warren was keen to emphasise that BIM did not stifle creativity. The ability to quickly test alternatives and see the potential impacts across all the professions had proved to be a major benefit of BIM in the development of design. However, recent experience had taught
him that technology was not yet in a position to usurp ‘felt tip’ sketches as part of the early conceptual work. Warren felt that the responsibility for
overall maintenance of the integrated model would inevitably be influenced by the nature of the project. The architect would be the default leader of the process, he claimed, but where there was significant M&E content, then the engineering services consultants would be the obvious BIM controllers. Rob Manning, CIBSE past-president and
BIM delivery director at the Construction Industry Council, stressed that BIM was about outcomes – from the project brief through to building operation, the success should be clearly benchmarkable. And by using fully integrated BIM, the output can feed back through the design process to improve successive designs. Concluding the seminar, Manning cited
the day as evidence that ‘BIM’ clearly meant different things to different people. He said BIM was not a panacea for poor design. But, he added, the consensus from the day was that great riches potentially could be gained from adopting the philosophy and implementation of BIM. However, reaping those benefits would
require a change in the perceptions, practices and expectations across the whole industry,

from manufacturer to building operator, and from designer to facilities manager. The driver for change is being accelerated by government mandate, he concluded, and it was clear that the riches would reach far beyond the clutches of the government estate. CJ

First BIM survey in building services engineering sector A survey was undertaken with the assistance of the CIBSE BIM Group earlier this year as a means of contributing some intelligence on the current state and appreciation of ‘BIM’ in the building services sector. This is thought to be the first such survey aimed at those in building services engineering, and so provides a starting point for future work.
cataloguing) of their ‘objects’. Perhaps not surprisingly as the survey was aimed at building services engineers, more than a third considered that CIBSE should take the lead in BIM standardisation for building services; but almost an equal number considered that a group
of institutions/associations should work together on BIM. From all the respondents, whether active users or not, there seemed to be an overwhelming need for an independent library of generic building services BIM objects.
The majority of the 83 respondents were building services consultants and ‘designers’. Just over half considered that they had at least a good working idea of how BIM was applied, and fewer than half had been actively involved in BIM-enabled projects over the past year.
The majority of those applying BIM in some way currently use Revit. For BIM ‘components’ they either created the objects themselves, went to the manufacturer or used an in-house library.
More than two-thirds of users are looking for generic (non- proprietary) BIM content that is broadly at ‘level 2’ – defined as content that has some parametric detail and contains information for approximate visual rendering (not to be confused with the BIM maturity level 2 being demanded by the government’s BIM strategy, which is an organisational level rather than a component ‘level of detail’).
Most BIM users did not show any particular preference for the method of categorisation (or
