Hello,
I have a client that is proposing to build a hotel (7 stories, concrete construction, basement level at 2.5m). The hotel will be adjacent to a railway mainline, with the tracks approximately at the same level as the finished ground level of our building. The edge of the building will...

I have an excavation extending 25 feet below the ground surface in compact to dense silts with trace sand. The GWT is located at approximately 15 feet. Excavation below the GWT as can be imagined is difficult, with the saturated soils very susceptable to remoulding with a minimal amount of...
