Geotechnical Investigation Program. TxDOT has performed certain geotechnical investigation work for the Project site. The Reference Information Documents include available geotechnical information collected by TxDOT to date. If Proposers wish to conduct their own geotechnical investigations on TxDOT ROW, Proposers must coordinate their activities with TxDOT. Proposers must obtain permits through TxDOT’s normal permitting process prior to performing any drilling on State ROW. A copy of the permit application containing applicable requirements and contact information will be provided in the Reference Information Documents. Destructive testing or drilling/coring of pavements will not be permitted.
Geotechnical Investigation Program. TxDOT is currently undertaking a geotechnical investigation program which began in July 2003 and is comprised of two phases. Phase 1 includes 90+ core holes to supplement prior work efforts to provide information concerning the geological conditions of the Project. The results of these borings are provided in a Geological Data Report (GDR) and is available to Proposers. Other relevant Project geological information includes the Geological Investigation Program (Phases I and II) scope of work and Geological Field Manual, each of which is included in Exhibit A. Phase 2 includes 40+ cores. Phase 2 also contemplates preparation of a “Geological Baseline Report B (Bidding)” (GBR-B) for the mined tunnel portions of the Project which will be made available to shortlisted Proposers. Rock core holes for Phases 1 and 2 have been retained for viewing by Proposers at a local facility. See the Website (as defined in Section 3.4) for viewing details or contact the Dallas District Office for viewing detail updates. For the month of June 2005, every Tuesday from 9:00 a.m. to Noon a joint viewing will be held at the stored core location facility.
