You are reviewing a Foundation Investigation and Design Report (FIDR) for a structural culvert replacement on Hwy 400. The existing culvert has a span of 3 m and a rise of 2 metres. The cover above the culvert is 5 metres. The subsurface conditions consist of approximately 5 to 8 metres of a compact sand fill underlain by a native deposit of compact to dense sandy silt approximately 10 metres in thickness which in turn is underlain by deposit of sand and gravel glacial till. The groundwater table is at the fill/native soil interface. Describe design and construction considerations that are to be included in the Foundation Investigation and Design report.
