045-10 Wyo. Code R. § 10-9
The bidder is required to examine carefully the site of the contemplated work, the proposal form, the plans, the specifications, the supplemental specifications, the special provisions, and the contract form pertaining to the project to be bid upon. In all cases, the Superintendent will assume that the bidder has inquired into and satisfied himself as to the conditions to be encountered in the performance of the work as well as to the requirements and provisions of the proposal forms, the plans, the specifications, the supplemental specifications, the special provisions and the contract form pertaining to the construction project. Although test borings are made and recorded with reasonable care and accuracy, and the results are furnished with the plans, the Department will not be responsible for full accuracy of sub-surface information. The bidder is expected to use such information as a guide in making his own determination of sub-surface conditions and will be allowed no additional compensation because of changes in character or amounts of material encountered.
