Public Comment Period Opens On Updated Professional Standard
June 14, 2016

The American Society of Civil Engineers (ASCE) will conduct a public comment period on the update to ASCE/EWRI Calculation of the Saturated Hydraulic Conductivity of Fine-Grained Soils. The public comment period will be held June 10 through July 25, 2016.

This is a standard guideline for calculating the saturated hydraulic conductivity (), permeability (), and porosity () of fine-grained, isotropic, and homogeneous soils using (i) strain-stress data from the incremental loading of a soil sample in a standardized consolidometer (step-load test), (ii) 1D vertical consolidation theory relating to the coefficient of consolidation (), (iii) the relation between and, (iv) the relation between porosity and the void ratio of a soil undergoing primary consolidation.

Accessing the Public Comment System will require using or creating an ASCE web user account. For additional questions contact James Neckel, ASCE’s Codes and Standards coordinator, at
