What Infrastructure Condition Index measures, and what it does not
It reads the records a building already has. Nobody visits the property.
Method status. Method 2.1, internal and pre-ratification, in a working prototype. It has not been externally reviewed, validated against outcomes, approved by any standards body or certified. Where it cannot support a condition result, it withholds one rather than estimating.
Condition and evidence are different
Condition describes the physical state of a system. Evidence describes how much is known about it.
Missing paperwork does not lower a condition result. What does affect it: how far a system is through its expected life, and documented physical findings, including findings a contractor recorded during a service visit. Age counts once.
Why a result is sometimes unavailable
No approved method
Some systems have no settled way to judge condition from records. The electrical panel is the clearest case.
Not enough on record
Without an installation date there is nothing to place a system in its life.
Main systems unresolved
A whole-property result needs every main system identified and assessable.
Not yet known
A system you have not told us about is recorded as not known, never as absent.
A system shown without a condition result is not a system in poor condition.
What it does not do
It is not an inspection, a certification, a code or compliance review, a safety assessment, an engineering opinion, a valuation or a warranty. It does not predict failure or tell you when to replace anything. It reports what you enter, and does not verify it.
It is not an energy rating. It may sit alongside an approved energy evaluation and does not calculate, replace, update or certify one.
Technical disclosure
Every result carries the version of the method that produced it, so a result stays interpretable later and historical results are never silently recomputed.
Condition covers mechanical and energy systems. Fire suppression, elevators and life-safety systems are outside this product and are not assessed. Records are kept in three separate groups: Condition and lifecycle; Safety and mandatory obligations; Contractor and service evidence. They are counted separately and never substituted for one another, so a missing permit is a gap in paperwork and not a finding about the physical condition of anything.
Regional weather, hazard and seasonal information may prompt attention, guidance or a request for evidence. It never changes a condition result on its own. A result changes only from evidence about that specific property.
The scoring method itself is proprietary and is not published.
