A couple of comments to add to the mix: (01)
1. In the context of the BIMstorms and what we have dubbed as 'BIG
BIM'; BIM is an organizing structure for data connecting to a
geolocated entity in the built environment. It is not a physical
model. The data interacting via the BIM can come from anywhere and can
be touched/manipulated/evaluated/etc. by anyone (or anything). (02)
- If someone still needs to see plans & specifications, they can. Even
though in this environment it is totally unnecessary.
- If someone else needs to see how a change to a parameter affects
their business metrics, they can.
- If a building system component needs information to drive a
function, it can pull the data and push the results.
- If an external event relates to or affects the entity, the BIM
reacts appropriately (issuing warnings, adjusting metrics, etc.). (03)
It is very much a living, breathing virtual construct of reality with
all the associated interactions and issues. (04)
2. In light of the above and the information recently posted, is this
really about figuring out the metrics and mechanisms that will all
input and feedback (actual performance) to design/implementation? If I
follow the discussion it seems as though the missing ingredients are: (05)
- standards that describe needs over the lifecycle of the entity
(agreed upon performance metrics)
- ways for the entity to measure against the standards
- feedback to the entity that tells it what is actually happening and
then evaluates the feedback in light of the standards. (06)
All done in ways that allow anyone (or anything) to drill down to the
finest detail or to simplify the data to fit their individual need,
whenever and wherever. They get just the right information for each
specific condition, no more no less. (07)
I may be looking at this too much of the project delivery perspective.
However, when the BIM is seen as the ultimate data aggregator;
building services performance components become input/feedback loops
directly interacting and reporting whenever and wherever necessary. (08)
