TIME OF COMMENCEMENT AND COMPLETION 2.1 The Contractor shall commence the Work upon the date established in the Notice to Proceed. 2.2 The Contractor shall achieve Final Completion, as defined in Section 105.01, Contract Time, Notice of Contract Execution and Notice to Proceed of the Loudoun County Revisions to the 0000 XXXX Xxxx & Bridge Specifications, Division I - General Provisions, within one hundred and eighty (180) calendar days from the date specified in the Notice to Proceed. This time period shall be designated the Contract Time. The Notice to proceed will be issued approximately than thirty (30) days after the execution of this agreement. The Contractor agrees that the time for completion of the Work as described in the Contract Documents shall govern unless specifically amended in writing by the County, and that no claims for early completion are allowed to be presented by the Contractor to the County. 2.3 The County specifies that time is of the essence under this Contract. Time being of the essence, it is essential to the County that Contract work will be completed within the Contract Time. The County and the Contractor agree that damages for failure to complete the work within the Contract Time are not susceptible to exact determination but that $600 per day is in proportion to the actual loss that the County would suffer from such delay. Therefore, the Contractor will pay the County on demand $600 per day for each and every day beyond the one hundred and eighty (180) calendar days, or modified date of completion, that the County determines that work is not complete, as damages caused by such delay and not as a penalty. The County shall be entitled to offset liquidated damages against any sum owed by the County to the Contractor under this Contract. 2.4 The amount of liquidated damages set forth in Articles 2.3 above shall be assessed cumulatively. This provision for liquidated damages does not bar County's right to enforce other rights and remedies against Contractor, which are otherwise legally enforceable, including but not limited to, specific performance or injunctive relief. 2.5 The Contractor hereby waives any defense as to the validity of any liquidated damages stated in this Agreement as they may appear on grounds that such liquidated damages are void as penalties or are not reasonably related to actual damages.
