– all efforts required to prepare and deliver a project‟s environmental documents in the preconstruction required to produce the project‟s construction documents. The summation of these components is a project‟s total PE. All PE tasks occur in the preconstruction phase. The personnel involved in planning VTRC defined PE as “the development of a project and the expenses to be incurred when a project advances from planning to design to when the project design is complete.” The VTRC researchers noted “ROW and PE are the states‟ most difficult cost categories to estimate and often present the greatest challenges and deviations with the cost estimation process.” Most respondents reported that PE costs
“the work that goes into preparing a project for construction.”
. To verify that the template‟s PE cost curve was applicable for statewide use, estimate costs of design consultants‟ efforts. The model was based on data from 59 Illinois Department factor assigned to assess the anticipated difficulty level of design. Nassar‟s research did not address how this value was assigned, but did note that process was “controversial” [Nassar et al. 2005].

DOTs lack integrated databases making the data “less useful and less available.” Wilmot et al. suggests that DOTs would benefit from using “integrated client server databases” [Wilmot et al. 1999].Construction estimates are prepared at multiple times within a project‟s lifecycle. Few details are known definition should be “the primary characteristic to categorize estimate classes.” As a project progresses
estimating accuracy for each researcher‟s classification varies. Table 2.2 provides a comparative –
