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 featw-es may become apparent as the
work progresses, which will result in an increase in cost.
