True concurrency requires that independent delays each affect the critical path during the same period. Where an owner-caused and contractor-caused delay overlap, most approaches grant time but deny compensation.
Apportionment approaches vary.

Why it Matters?
The typical resolution grants a time extension while denying delay damages to both parties, which makes concurrency a defense for owners facing compensable delay claims and a defense for contractors facing liquidated damages. That symmetry is why establishing concurrency is frequently the most productive schedule analysis. Proving true concurrency requires showing both delays independently affected the critical path in the same period.
