Before submitting a bid in excess of $2,000,000, the Bidder shall have been prequalified with the Department and received a Certificate of Qualification in accordance with the Rules and Regulations approved and adopted by the State Transportation Board. Bidders submitting bids of $2,000,000 or less shall have been registered with the Department. In addition, the aggregate total amount a Bidder may have under contract shall not exceed the Current Capacity of the Bidder.

Bidders intending to consistently submit Proposals shall prequalify at least once every two years. However, qualifications may be changed during that period upon the submission of additional favorable reports or upon unsatisfactory performance. In addition, the Department reserves the right at any time to require the Contractor to furnish a current financial and experience statement.

102.02 Competency of Bidders

The Department may limit the amount of work awarded to any Contractor, based on the information furnished the Department in the Prequalification process. The Department may also limit the aggregate amount of work awarded to any non-prequalified Contractor.

The Department may refuse any Contractor Proposals to bid on additional work if the Contractor is behind schedule on work he has with the Department, as determined from the Progress Schedule called for in the Specifications. This refusal will apply to all applications for Proposals, made in the name of an individual, firm, partnership, or corporation with which the delinquent Contractor is affiliated.

102.03 Contents of Proposal Forms

The Department will make available to the prospective Bidder a Void for Bidding Proposal Form which may be accessed on the Office of Construction Bidding Administration web page. This form will state the location and description of the contemplated construction and will show the approximate estimate of the various quantities and kinds of work to be performed or materials to be furnished and will have a schedule of Items for which Unit Bid prices are invited. The Proposal Form will state the time in which The Work must be completed, the amount of the Proposal Guaranty, and the date of the opening of Proposals. The Form will also include any Special Provisions or requirements that vary from or are not contained in the Specifications. Also included with each Proposal Form will be a Non- Collusion Certificate, Construction Contractors Bid Opportunity List, and Request for Eligibility to Bid. All papers contained in the Proposal Form are considered a part thereof and must not be detached or altered.

102.04 Interpretation of Estimates

The quantities of work to be performed and materials to be furnished to complete the construction of The Work as shown on the Plans and contained in the Proposal are approximate and are to be used for comparing Bids. The Department does not guarantee that the quantities indicated on the Plans or given in the Proposal will be the actual construction quantities. The Contractor shall not plead deception or misunderstanding because of variation from these quantities or minor variations from the locations, or character of the Work. Payment to the Contractor will be made only for the actual quantities of work performed in accordance with the Plans and Specifications. If, when construction is completed, the actual quantities are more or less than the quantities given in the Proposal, the Unit Prices Bid in the Proposal will still prevail, except as otherwise provided in Subsection 104.03 and Subsection 109.05.
