Disruption addresses inefficiency rather than schedule extension, and may occur without any delay to completion. Causes include out-of-sequence work, trade stacking, restricted access, and excessive change orders.
Quantification is the principal difficulty.

Why it Matters?
Disruption can occur without delay, which parties frequently conflate, and a project finishing on time may still support a substantial disruption claim where the contractor absorbed inefficiency to maintain the schedule. Quantification is where these claims succeed or fail, and the measured mile comparison of impacted against unimpacted periods is the most credible method. Total cost approaches invite challenge because they assume all overrun was owner-caused.
