An online journal documenting the planning and building process of our modern home from start to finish. It is intended to share our experiences throughout this project with all those interested in modern design.

Geotechnical Evaluation

We received the Geotechnical Report from CVT on December 30th. Overall, it was good news to know that competent bedrock was between 12' to 17' deep. To summarize, There is about 3-4' feet of brown silty clay under the topsoil, then around 2-4' of light brown silt, then some 4-11' of orange fine graded sand, then orange/yellow/white standstone. The boring logs can be found here. Here is a map showing the clearing and the approximate boring log locations:

Recommendation is to remove the topsoil, clay, and silt and to anchor the foundation into the sandstone in areas closer to 50' from the top of the slope. Looks like we can build the house, the question is what kind of foundation will be needed.
