A change order is a formal document that modifies the original construction contract. It is typically used to document changes in the work scope, adjustments in contract time, or alterations to contract price estimates. This type of alteration is substantial because it not only changes specific aspects of the project but also usually necessitates negotiation and agreement between the contractor and the client or project owner. It reflects a significant alteration in the terms of the original contract that both parties must recognize and agree upon.

In contrast, addenda are generally used to clarify or modify the bidding documents before the contract is signed, and while they can alter project specifications, they do not constitute a contract change once the project is underway. Field orders, on the other hand, are typically minor changes or clarifications that a contractor can proceed with immediately without the extensive negotiation process involved in a change order. A bid bond serves a completely different function, as it is a financial guarantee required when a contractor bids on a project to ensure that they will honor their bid if selected; it does not alter the construction contract itself in any way.
