This document is a memorandum dated October 15, 2012, detailing the foundation conditions exposed and prepared for the RCC spillway crest raise at Mount St. Helens. It describes the river diversion process, original foundation excavation, and the subsequent clean-up and preparation of the foundation. The document notes that the foundation rock was highly broken and fragmented, likely due to original construction blast damage and sediment deposition. It details the methods used for cleaning the foundation, including mechanical equipment, sweepers, and high-pressure air streams, aiming to expose at least 50% rock fragments. Geologic mapping was conducted to differentiate areas of intact basalt, flow breccias, and fragmented rock. The document also addresses foundation drains, concerns about backward erosion, and future considerations for the spillway raise.

This document provides critical geotechnical information about the foundation conditions for the spillway crest raise. Bidders involved in any future construction or maintenance related to this structure would need to understand the nature of the foundation, including its fragmented state, potential for seepage, and the measures taken to ensure its adequacy. The information on excavation, cleaning, and foundation mapping is relevant for assessing site conditions and potential challenges during any related work.
