To evaluate overall building condition, the Facility Condition Index (FCI) is commonly used. FCI = Deferred Maintenance ÷ Current Replacement Value. A lower FCI indicates better building condition (less deferred maintenance relative to value).

Building 1: 1,200,000 ÷ 25,000,000 = 0.048

Building 2: 200,000 ÷ 2,500,000 = 0.080

Building 3: 25,000 ÷ 600,000 = 0.0417

Building 4: 900,000 ÷ 10,000,000 = 0.090

Building 3 has the lowest FCI (0.0417), which means it has the least deferred maintenance compared to its value and therefore is in the best overall condition.

Incorrect Options:

Building 1 (0.048) – Good, but not the lowest.

Building 2 (0.080) – Higher FCI means poorer condition.

Building 4 (0.090) – Highest FCI of the group.
