Anticipated contractor-furnished borrow needs

Disclaimer
This is advance notification of anticipated needs for contractor-furnished borrow material.  It is the best information available at the time of posting but design details and letting dates are subject to change.  Estimated letting date information is updated routinely at: http://www.iowadot.gov/contracts/lettings/Target.pdf .

Any borrow information provided is for information purposes only. The information presented, consisting of prospective borrow locations, boring locations, boring logs, and lab test results on soil samples, may or may not have been complete when originally obtained for the Iowa Department of Transportation. Therefore the information may or may not be complete for the purposes of a contractor’s borrow selection. The information is provided “as is” and does not necessarily represent any final review, evaluation, selection, or borrow intent by the Iowa DOT. The contractor is responsible for review and evaluation of the data, and how it may apply to the contractor’s selection for borrow. The contractor must follow the specified requirements of the contract documents when applying the information to any borrow site selected by the contractor.
