Those acts, omissions, conditions, events, or circumstances that are beyond the control of the collaborative delivery firm and are not the fault of either the firm or others for whom the firm is responsible. Examples of uncontrollable circumstances include: acts or omissions of the owner or anyone under the owner's control, changes in the scope of work, differing site conditions, hazardous conditions, wars, floods, labor disputes, unusual transportation delay, epidemics, earthquakes, adverse weather conditions that cannot reasonably be anticipated, and other circumstances beyond the reasonable control of the design-builder or CMAR firm. An uncontrollable circumstance might lead the firm to seek a change order that would provide schedule and cost relief under the contract.
