I would say it needs to. Answering these and a few other practical questions is what the base data requirement in COBie does and is then extended to cover other plain language questions via project data requirements. More info from the UK BIM Alliance – Project Data Requirements – UK BIM Alliance
Purposefully trying to think of an example where the “always” part of the statement might not apply… I could imagine scenarios involving mobile assets where always knowing location isn’t practical or cost effective. A twin might know that something has left one place on route to another but hasn’t arrived, has left a place but hasn’t returned yet, or entered an environment where reporting on position isn’t possible. The location isn’t immediately unknown but a prediction that decreases in confidence as the time between known locations increases.
I think I have thought myself into the position that it might be OK for twins to lose things! in scenarios where the cost of knowing where everything is all of the time is greater than the cost of occasionally losing things.
I probably wont remember this logic next time I can’t find my keys 😀
