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.
