The purpose of this work is to complete a comprehensive stability, seepage, deformation, and risk evaluation of the embankment and abutments at Duncairn Dam. Instrumentation data installed to date indicates cyclic deformation resulting from reservoir operation. Based on the history of the site and limited data regarding deformations experienced, WSA desires additional analysis of the site using numerical model stability and deformation assessment.
The scope of the work is to provide consulting services to:
a) Complete stability, seepage, and deformation assessment of Duncairn Dam,
b) Complete a risk assessment,
c) Update geotechnical instrumentation alarm levels.
