Engineer's Opinion of Probable Construction Cost
ABEI No. 1044001
September 23, 2002
The following construction estimate is based on the engineer's opinion of probable
construction costs. This estimate constitutes our best judgement 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.
