Time Extensions for Karst Feature Mitigation. Subject to Section 4.6 of the General Conditions and this Section 6.9, DB Contractor shall be entitled to an extension of applicable Completion Deadlines for delays to a Critical Path attributable to Karst Feature Mitigation (“Karst Mitigation Delay”). A Karst Mitigation Delay begins on the date DB Contractor commences Karst Feature Mitigation activities following TxDOT approval of the Karst Feature mitigation plan for the applicable Karst Feature and ends when the DB Contractor completes such Karst Feature Mitigation activities in accordance with the Karst Feature mitigation plan. The risk of Karst Mitigation Delays shall be borne equally by each Party (i.e., any affected Completion Deadline shall be extended by one day for every two full days of Karst Mitigation Delays). If a Karst Mitigation Delay is concurrent with another delay that is DB Contractor’s responsibility under the Design-Build Contract, then DB Contractor shall bear 100% of the risk of such Karst Mitigation Delay. If a Karst Mitigation Delay at one location is concurrent with another Karst Mitigation Delay at one or more other locations, the delays at the locations shall run concurrently and each day of such concurrent delay shall be deemed a single day of Karst Mitigation Delay.
