||The Unit Bid Analysis (UBA) contains the bid history for Standard Bid Items used in WSDOT projects. |
This Bid History data includes a listing of projects in which a bid item was used, the Low, Second and Third bidder information for those projects, as well as the quantity and measurement data.
|The Unit Bid Analysis Provides a good starting point for determining Bid Item costs |
|The Unit bid analysis information provided here is a good place to start, but each project is different and there are many factors that need to be considered to develop an accurate letting estimate using historical bid prices.|
Some of these factors include: Geographical Location i.e. urban/rural; Quantity, Generally the unit price for large quantities of a given material will be less than for small quantities; Availability; Scheduling,Site constraints and Bidding Environment.
