The above construction estimate is based on the engineer's preliminary opinion of probable construction costs. This estimate constitutes
our best judgment at this time. Please note that the engineer does not have any control over contractor or supplier workloads and the
degree to which inflation may affect project costs between now and the bid date. During construction, additional features may become
apparent as the work progresses. which will result in an increase in cost.
