Subject: Compilation of Geotechnical References, Beartooth Highway Project, WY HPP 4-1(4)

Since 1998, CFLHD has undertaken numerous geotechnical investigations along the (4) segment of the Beartooth Highway, ranging from conventional subsurface drilling and test pit investigations to state-of-the-art geophysical surveys. As a result, nearly thirty formal reports and/or Technical Memoranda have been produced covering a wide variety of topics, including bridge and retaining wall foundations, earthwork, rock slopes, material sources, and landslides, to name just a few. To assist Contractors in identifying relevant geotechnical references during construction, this memo presents a compilation of all related reports and memos, highlighting general contents of each, and conveniently tables priority references by geotechnical subject.

Each of the referenced documents, including all contract reports, is available from CFLHD.

The reference numbers provided in this table refer to the complete references given in the next section. The primary geotechnical reference for the (4) project is the comprehensive study

Technical Memorandum

Date: November 24, 2004 performed by URS and reported on in the spring of 2001 (Reference 7). Reference numbers are listed in the approximate order of priority, with primary documents (first reference number in the list for a given topic) representing the latest engineering values or design summaries, or the greatest source of overall topic information.

The Contractor is cautioned that while later documents may contain information that supercedes prior documents, they may not be comprehensive in application. It is recommended that all reports pertaining to a particular subject be reviewed. Also, stationing referred to in the above table, and the following reference listing, is the stationing current at the time of the report.
