1.03 WITHDRAWAL OF BIDS

A. After the specified time, no bid may be withdrawn for a period of ninety (90) days or until a contract is awarded, whichever occurs first.

1.04 ACCESS TO AND INSPECTION OF PROJECT SITE

A. Offerors may arrange for access to the Site by contacting ENGINEER at any time between publication of the publication and the deadline for receipt of bids. Such access will be granted to allow Offerors to make a complete inspection and careful examination of the project site and familiarize themselves with the soil and water conditions to be encountered, construction to be projected, disposal sites for surplus materials not designated to be salvaged materials, method of providing ingress and egress to private properties, and methods of handling traffic during construction of the entire project.

B. By submitting a propos, Offeror acknowledges it has inspected the site, has read and become thoroughly familiar with the plans and contract documents (including all addenda).

1.05 GEOTECHNICAL DATA

A. The locations of the test holes, if applicable, are shown in the Geotechnical Report. Logs of these test holes are included in the Geotechnical Report. Test holes information represents subsurface characteristics to the extent indicated and only for the point location of the test hole. Each Offeror shall make his/her own interpretation of the character and condition of the materials which will be encountered. Each prospective Offeror may, at his/her own expense, make additional surveys and investigations as he may deem necessary to determine conditions which will affect performance of the Work.
