Rock Slope Stability at Valdez Marine Terminal Contract Change Order TOEM Committee RCAC Staff Tom Kuckertz 1/25/2007 Board Meeting
Change Order Rock Slope Stability Efforts • Contract objective: – To evaluate the stability of the rock slope at and above the VMT – To determine its probability of failure during serious seismic event. • Availability of detailed geologic data was limited: – on the rock, rock type, structure, nature and spacing of fractures, shear strength of fractures and of intact rock strength – necessitated additional efforts and expenses • Action Requested: – Authorize the Executive to increase the total value of Contract 556.07.01by $2,000. – Authorize an increase of $2,000 in the budget for Project 556 to be taken from contingency. 1/25/2007 Board Meeting
