Concurrent Delays

A delay is “concurrent” is a delay to the critical path of the project caused by multiple events not exclusively controlled by one party. If you are impacted by a delay to the critical path that was not within your control but are responsible for another overlapping delay to the critical path, the delays are concurrent, and you may not be able to recover damages for the former delay. You may, however, still be entitled to an extension of the contract time, which is usually classified as an “excusable delay” (contrast, with “compensable delay” where time and money are recoverable).

The Critical Path

A contemporaneous delay that does not affect the critical path may not be “concurrent” for purposes of schedule review and analysis. Similarly, if the critical path is delayed simultaneously by two separate events, both outside your control, neither delay will be considered concurrent with respect to your delay claim or defense of the same. However, if the delay impacts from those two events run simultaneously, you may not be entitled to double or duplicative recovery. You will only be able to recover for the actual delay to the critical path.

Schedule Updates

On complex construction projects, with multiple overlapping activities and, sometimes, multiple critical paths, determination of concurrent delays can be difficult. In such circumstances, it may make sense to staff a scheduler to a project full time or even hire an outside scheduling consultant to review and update your schedule regularly as the project progresses and impacts accrue. If you end up in a dispute or claim with a subcontractor, owner, or other party, having consistent and quality schedule updates will help you analyze the different delays to the project and determine responsibility and concurrency.

Closing Thoughts

Concurrent delays can have a substantial impact on delay disputes on construction projects. If you have, or are facing, a big delay claim, being able to map out possible concurrency will help you value your claim or your exposure better and help you make better commercial and litigation decisions.

Additionally, note that concurrency is a difficult concept for many trained professionals in the construction industry. If you are heading down the path towards litigation, you might also consider concurrency in the context of how a lay judge or jury may view the concept.
