An estimating question...
(OP)
Does anyone know of a rule of thumb for estimating how much of a mechanical cost in a new building is actual equipment (pumps, boilers, chillers, etc.) less piping, valves, fittings, insulation, etc. I'm trying to estimate value for asset management without doing a breakdown. More or less for conversational purposes.

The rule of thumb is that their is no rule of thumb and even for feasibility estimates. I still perform a level of breakdown unless it is of no importance at all.
Regarding the the life cycle, everything manufactured has an mtdf (mean time before failure) this is relative again, to environment, presumed level of maintenance, use, how it is managed, and finally the original design in terms of under / over sized criterion. (for replacement value) This is "presumed" the existing technology isn't antiquated by the end of its life or even abandoned all together.

for Heating, ventilating, air conditioning of course for different types of buildings the cost per sq ft will be different
