A Concurrent Delay Analysis clause addresses situations in real estate and construction projects where multiple causes of delay occur simultaneously—some attributable to the contractor and others to the client, weather, or third parties. This clause establishes the methodology for determining responsibility and entitlement to time and cost extensions when delays overlap. Without clear language, concurrent delays create significant disputes: a contractor may argue they're entitled to a time extension and delay damages because the client caused a concurrent delay, while the client argues the contractor would have been delayed anyway due to their own inefficiency. The clause typically specifies whether concurrent delays result in no time extension (the "but-for" rule), a shared extension, or full extension to the contractor, and it may require detailed critical path analysis to determine which delays actually affected project completion. This matters because concurrent delays are common in complex projects, and the clause's language directly determines millions of dollars in potential liability.

💡
Key Recommendation

Clearly define in the contract which party bears the burden of proving concurrent delay and require that any claim for time extension include a detailed critical path analysis showing exactly how each delay affected the overall schedule. Consider adopting the "apportionment" approach where each party bears responsibility for delays they caused, rather than the all-or-nothing approach. Establish a procedure for prompt notification and documentation of delays as they occur, and consider requiring independent scheduling experts to resolve disputes about concurrent delay causation. Both parties should understand that vague language on this issue virtually guarantees litigation.
