Each Bid shall be made on the Bid Form provided in the bid packet and no Bidder may withdraw their Bid for a period of ninety (90) days from and after the date set for opening of bids. Each Bid must be accompanied, in a sealed envelope, separate from the one containing the Bid, by a Bid Bond on an approved form in an amount equal to ten percent (10%) of the Bid price, made payable to the City of Centennial, which shall be considered as liquidated damages and shall be forfeited to the City if said Bid is accepted and the Bidder fails to execute the Contract within ten (10) calendar days after the Award by the City. Each Bid must also be accompanied by a completed Questionnaire and Proposal not more than ten (10) pages in length.

The work herein provided for shall be done under written Contract with the contractor chosen by the City as deemed to be in the best interests of the City. Upon review of Bid prices, the Questionnaires, and the Proposals, the City may be required to add or delete portions of Work from this Project.

The successful Bidder will be required to furnish, as part of the Contract, insurance certificates in the amount specified in the General Conditions, a Performance, Payment, Maintenance and Warranty Bond in an amount equal to one-hundred percent (100%) of the Contract Sum, said bond to be issued by a responsible corporate surety approved by the City, and which shall guarantee the faithful performance of the Construction Contract and the terms and conditions therein contained and shall guarantee the prompt payment of all materials and labor, and protect and save harmless the City from claims and damages of any kind caused by the operations of the Contractor.

The bid preference shall not be applied to any work that receives federal moneys.

The bid preference required by Article 19 of Title 8, C.R.S. shall be suspended if such requirement would contravene any treaty, law, agreement or regulation of the United States, or would cause denial of federal moneys or preclude the ability of the City to access federal moneys that would otherwise be available.

However, if Bidder satisfies 1 through 3, the City intends to redact or withhold such identified and segregated material in response to a CORA request.

If Bidder fails to enter into such agreement, it shall be discretionary with the City whether to defend the legal challenge.

12.06 Bids that are not completed in the form and manner required by this IFB are subject to immediate rejection in the discretion of the City of Centennial.
