Is the Contractor expected to have previously visited the Contract site in preparation for his bid?

Yes. Before the bidding and the awarding of the Contract, the Contractor is expected to have visited the project site and made his own estimate of the facilities required in and difficulties attending the execution of the Work, on account of local conditions and all other contingencies.

 

The Owner shall, however, furnish the Contractor a geodetic survey and sub-surface exploration which the Contractor is entitled to rely upon in the preparation of his Bid.
