IS 10060 : 2013 : Geotechnical Investigations for Power House Sites - Code of Practice

ICS 93.020 WRD 5

Reaffirmed 2019

1. Scope

1.1 This standard gives guidance on the type, extent and details of subsurface exploration needed in connection with hydroelectric power houses both surface and underground.

1.1.1 This standard provides guidelines for planning the exploratory work, through various stages of the project development. These recommendations may have to be modified for individual projects, depending upon the site conditions and other conditions peculiar to each project, such as height and importance of the power house and the heterogeneity of foundation formations.

1.2 The term subsurface exploration, as used herein, covers all types of exploration connected with determination of the nature and extent of surface and subsurface media at or near the power house site.

1.3 This standard does not, however, cover the types and methods of exploration for materials of construction for power houses, such as, aggregate and material for riprap.
