Which of the following is NOT typically included in supplementary conditions of a contract?

In the context of contract management, supplementary conditions are intended to modify or add to the general conditions of the contract to outline specific details pertinent to a project. The correct answer identifies that change orders are not typically included in the supplementary conditions.

Change orders refer to amendments to the scope of work after a contract has been executed and usually involve adjustments to the contract price and/or completion timelines. They originate from the initial contract agreement's terms, which detail how modifications should be managed. Hence, change orders are generally treated as separate documents and processes rather than part of the supplementary conditions.

On the other hand, delay agreements, time and pay schedules, and addendums can be included in supplementary conditions as they provide clarity and details specific to a project. Delay agreements can specify conditions under which work might be postponed, time and pay schedules outline the timing for performance and payments, and addendums serve to add information or modify contract terms, which aligns perfectly with the purpose of supplementary conditions.
