There are not many people or organizations that can say they anticipated the spread of this pandemic disease that is confining million to their homes as part of stay in place orders and self quarantines.
Though the FAR Council did not foresee that the coronavirus and COVID-19 would trap contractors in their homes, it did anticipate that from time to time events completely out of the control of contractors may conspire to affect the performance of contracts—though perhaps not to this magnitude.
Contract changes, particularly in the construction context, can be flash points for the Government and a contractor. In some cases, the Government will assert that the contract requires the contractor to perform certain work; the contractor, pointing to the same (or another) contractual provision, will argue that the contract does not require it.
These diverging positions can sometimes lead to contentious litigation.
