C. Change of Contract Times.
1. The Contract Times may only be changed by a Change Order.
2. All changes in the Contract Price and/or adjustments to the Contract Times related to each change shall be included in Contractor’s COR pursuant to this Article. No cost or time will be allowed for cumulative effects of multiple changes.
All Change Orders must state that the Contract Time is not changed or is either increased or decreased by a specific number of days. Failure to include a change to time shall waive any change to the time unless the parties mutually agree in writing to postpone a determination of the change to time resulting from the Change Order.
3. Notice of the amount of the request for adjustment in the Contract Times with supporting data shall be delivered within seven (7) Days after such start of occurrence, unless Town’s Representative allows an additional period of time to ascertain more accurate data in support of the request.

Any difference in time between the Contractor’s early completion and the Contract Time shall be considered a part of the Project float.
6. Contractor’s entitlement to an extension of the Contract Times is limited to a Town-caused extension of the critical path, reduced by the Contractor’s concurrent delays, and established by a proper time impact analysis. No time extension shall be allowed unless, and then only to the extent that, the Town- caused delay extends the critical path beyond the previously approved Contract Time. If approved, the increase in time required to complete the Work shall be added to the Contract Time.
a. Contractor shall not be entitled to an adjustment in the Contract Price or Contract Times for delays within the control of Contractor. Delays attributable to and within the control of a Subcontractor or Supplier shall be deemed to be delays within the control of Contractor.
b. If Contractor is delayed in the performance or progress of the Work by fire, flood, epidemic, pandemic, abnormal weather conditions (as det ermined by the Town), Acts of God, acts or failures to act of utility owners not under the control of Town, or other causes not the fault of and beyond control of Town and Contractor, then Contractor shall be entitled to an time extension when 25977.00100\34209346.1
-96- 00 72 13 – GENERAL CONDITIONS
the Work stopped is on the critical path. Such a non- compensable adjustment shall be Contractor’s sole and exclusive remedy for such delays.
Contractor must submit a timely request in accordance with the requirements of this Article.
c. Utility-Related Delays.
i. Contractor shall immediately notify in writing the utility owner and Town’s Representative of its construction schedule and any subsequent changes in the construction schedule which will affect the time available for protection, removal, or relocation of utilities.

ii. Contractor shall not be entitled to damages or additional payment for delays attributable to utility relocations or alterat ions if correctly located, as noted in the Contract Documents or by the Underground Service Alert survey.
7. Content for Requests for Contract Extension. Contractor’s justification for entitlement shall be clear and complete citing specific Contract Document references and reasons on which Contractor’s entitlement is based. At a minimum, each request for a time extension must include:
a. Each request for an extension of Contract Time must identify the impacting event, in narrative form, providing a description of the delay event and sufficient justification as to why the Contractor is entitled to a time extension.
Contractor must demonstrate that the delay arises from unforeseeable causes beyond the control and without the fault or negligence of both Contractor and any Subcontractors or Suppliers, or any other persons or organizations employed by any of them or for whose acts any of them may be liable, and that such causes in fact lead to performance or completion of the Work, or specified part in question, beyond the corresponding Contract Times, despite Contractor’s reasonable and diligent actions to guard against those effects.
b. Each request for an extension of Contract Time must include a time impac t analysis in CPM format, using the Contemporaneous Impacted As -Planned Schedule Analysis to calculate the impact of the delay event.
8. No Damages for Reasonable Delay.
a. Town’s liability to Contractor for delays for which Town is responsible shall be limited to only an extension of time unless such delays were unreasonable under the circumstances. In no case shall Town be liable for any costs which are borne by the Contractor in the regular course of business, including, but not limited to, home office overhead and other ongoing costs. b. Damages caused by unreasonable Town delay that impact the critical path, including delays caused by items that are the responsibility of the Town 25977.00100\34209346.1
-97- 00 72 13 – GENERAL CONDITIONS
pursuant to Government Code section 4215, shall be compensated at the Daily Rate established in the Special Conditions.

not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) sustained by Contractor on or in connection with any other project or anticipated project.
9. Contractor’s failure, neglect, or refusal to comply with the requirement s of the Contract Documents, or any portion thereof, shall bar Contractor’s request for extensions of the Contract Times. Such failure, neglect, or refusal prejudices Town’s and Town’s Representative’s ability to recognize and mitigate delay, and such failure, neglect, or refusal prevent the timely analysis of requests for extensions of Contract Times, and whether such extensions may be warranted.
Contractor hereby waives all rights to extensions of Contract Times due to delays or accelerations that result from or occur during periods of time for which Contractor fails, neglects, or refuses to fully comply with t he requirements of this Article.
