A constructive change typically arises from what kind of issue?

A constructive change typically arises from issues that create a misunderstanding or misalignment between the contract terms and the expectations or execution of work. The correct answer encompasses all of the potential sources of such issues.

Lack of contractor experience can result in the contractor being unable to interpret or execute the contract as intended, leading to disputes or changes being necessary to fulfill the contract's requirements effectively.

Ambiguity in contract language can create confusion or misinterpretation regarding the obligations of both parties. When contract terms are unclear, it can lead to disagreements about what was agreed upon, necessitating changes in the scope of work or adjustments to meet the interpreted needs.

Unclear government specifications can similarly result in a situation where the contractor is unsure how to proceed, potentially leading to changes once the intentions behind the specifications are clarified or revised to meet the project's objectives.

Each of these issues individually contributes to situations where changes become necessary, making "all of the above" the most comprehensive answer.
