Karst feature definition

Karst feature means an area or surficial geologic feature subject to bedrock dissolution so that it is likely to provide a conduit to groundwater, and may include caves, enlarged fractures, mine features, exposed bedrock surfaces, sinkholes, springs, seeps or swallets.

Karst feature means any subsurface cavity that: (a) is greater than six inches across in any direction; (b) is greater than one square foot along any plane; (c) blows air; (d) continually receives water during a rain event; or (e) has water flowing through or Karst Feature Mitigation Plan out of it. means a karst feature mitigation plan contemplated in the RID entitled “Karst Feature Discovery and Mitigation.” Karst Mitigation Delay has the meaning set forth in Section 6.9.3 of this DBA.

Karst feature means a cavity or cave formed by the dissolution of limestone by naturally occurring acids.

• 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 the performance of presence/absence surveys at a Karst Feature required by Section 12.2.5.8 of the Design-Build Specifications, and the need to work around locations subject to temporary no-work restrictions due to performance of such surveys (“Karst Investigation Delay”).

• DB Contractor shall provide TxDOT with such information, analyses and certificates as may be requested by TxDOT in order to enable a determination regarding eligibility for a Price increase or a time extension with respect to mitigation of a Karst Feature.

• Entitlement to compensation or a time extension for the mitigation of Karst Features shall be limited to Work performed to mitigate such Karst Feature pursuant to DB Contractor’s Karst Feature mitigation plan, as approved by TxDOT in writing.

• DB Contractor shall demonstrate to TxDOT’s satisfaction that DB Contractor’s Karst Feature mitigation plan represents the approach that is most beneficial to the Project and the public.

• DB Contractor shall bear 100% of the risk of Karst Investigation Delays up to 30 days per individual Karst Feature and up to a cumulative total of 60 days for all Karst Feature locations.

• If the Karst Investigation Delay exceeds 30 days for a particular Karst Feature, then the risk of such Karst Investigation Delay in excess of 30 days for that Karst Feature shall be borne by TxDOT.
