Historical Cost Data
The following information can be used for budgetary estimating, change order processing, or for any other item price verifications.
The Historical Bid Data Item Search are macro-enabled searchable Excel files summarizing item costs for 2010-2018. Each item is summarized by project, quantity, bid average, awarded bid, low bid, and high bid.
The Summary of Contracts Awarded are yearly summaries of item costs from 1999-2017. Each item is summarized by quantity, bid average, awarded average, and total amount awarded. The summaries are presented in Microsoft Excel and Adobe Acrobat format. The current year will be compiled at the end of the year.
Bid Tabulations are published after projects have been awarded. They are available from 2001-2017. The current year will be compiled into a single pdf file at the end of the year.
