The word 到 (dào) means "arrive," but it can also mean "to reach" or "to get to" in an abstract sense. So in this pattern, 不到 (bùdào) means "to not reach (the amount of)," or, to put it another way, "to be less than."

When 不到 (bùdào) is put before a time or a duration of time, it needs to be followed with 就 (jiù). This shows that something (usually referring to the past) has happened earlier than expected.

Subj. + 不到 + Time + 就 + Predicate + 了
