Final answer:
Archaeological work designed to mitigate damage during construction is called Cultural Resource Management, focusing on the preservation and sometimes restoration of heritage sites.
Step-by-step explanation:
In the United States, archaeological work that is undertaken to mitigate damage to sites due to construction or commercial works is called Cultural Resource Management (CRM). CRM embodies a range of procedures, including archaeological surveying, excavation, documentation, preservation, and sometimes, when necessary, restoration of cultural heritage sites. Such efforts align closely with conservation practices, which seek to protect and preserve cultural heritage for future generations. Unlike restoration, which may reconstruct or repair original structures or artifacts, conservation emphasizes preserving the current state of the site while allowing for reversibility of treatment in light of new scientific advancements or interpretations.
