Abstract

Geotechnical Baseline Reports for Construction: Suggested Guidelines examines the role of the Geotechnical Baseline Report (GBR) as a means of allocating and managing subsurface risks associated with subsurface construction. It discusses the importance and benefit of ensuring compatibility between the GBR and other contract documents, as well as the importance of involving experienced firms and individuals in the preparation and review process.

This report, prepared by the Technical Committee on Geotechnical Reports of the Underground Technology Research Council, expands on the previously published Geotechnical Baseline Reports of Underground Construction: Guidelines and Practices. It includes three new chapters on the application of GBR’s to other types of subsurface projects, the application of GBR’s in design/build project delivery, and recommendations based on industry-wide lessons learned. Other topics of this report include organization and content of a GBR, owners’ perspectives, and a discussion of the rational for the use of GBR’s as a risk management tool.
