An accurate estimation of a transportation project cost is essential to
ensure timely completion of such project within the available budget
that was approved during the fiscal year and long-term planning.
However, past studies have shown that transportation construction
project cost often exceeds the amount initially assigned during the
planning phase. If any project exceeds its budget, other projects may
be delayed or removed from the program, the project itself may be
halted, or the scope of the project may be reduced. Thus, a reliable
estimate must be prepared early during the project development
instead of waiting till the bidding phase. However, producing an
accurate estimate during the early phase is a challenge as limited
information about the project may be known at that time. As such,
instead of focusing solely on producing an accurate estimate, state
highway agencies should also consider identifying, evaluating, and
quantifying various risk factors that can affect the overall project cost. |
