Liquidated damages are assessed at $175.00 per day for all work except seeding and $125.00 per day for seeding activities to address project delays. The estimated total construction cost for the North site ranges from $375,000 to $475,000, while the South site ranges from $175,000 to $275,000, with compensation computed on a unit price basis and monthly progress payments processed at ninety-seven percent of completed work value, subject to a three percent retention.

The undersigned hereby agrees, if awarded the contract, to execute the proposed contract and to furnish satisfactory Performance Bond in an amount not less than one hundred percent (100%) of the contract award within fourteen (14) days from the date when Notice-of-Award is received, and to provide all supervision, labor, materials, and equipment required to complete the project designated above, for the prices hereinafter set forth, in strict compliance with the Contract Documents prepared by the Division.
Further, the parties agree and acknowledge as follows:
The amount of loss or damages likely to be incurred by Division are uncertain and said loss is incapable or very difficult to quantify and estimate;
The amount specified for liquidated damages herein bear a reasonable relationship to, and are not plainly or grossly disproportionate to, the probable loss likely to be incurred by Division in connection with any delay on part of the Contractor;
The amount of liquidated damages fixed herein bears a reasonable relationship to Division’s anticipated losses and/or actual losses;
The amount of liquidated damages herein fairly approximates Division’s loss at the time of making of this Agreement;
The amount of liquidated damages fixed herein are fair and reasonable and it approximates to the extent possible the actual loss to Division as a result of any delay on the part of Contractor; and
Division and Contractor are sophisticated parties and negotiated this Agreement at arm’s length.
Now therefore, in consideration of the mutual obligations set forth herein, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:
Contractor will commence the work after the Preconstruction Conference and by the Construction Start Date approved by Division in the Construction Progress Schedule.
Contractor will complete the work within the specified time period identified in the contract, or as amended, or be responsible for liquidated damages per day as set forth in the above table.
The liquidated damages may be withheld from payments made to the Contractor by the Division upon written notice that liquidated damages have begun to accrue, and such damages are in addition to other remedies available as provided for in this contract and applicable law.
A Proposal Guarantee in the amount stipulated herein is included with this proposal, to be forfeited to the Division, if the undersigned fails or refuses to execute the contract and furnish satisfactory Performance Bond, if awarded the contract.
