High Bearing Values

High Bearing Values and ABC Geotechnical Schedules

Here is one response that can be placed in the cover letter that sets out the limits where the bearing values are a bit on the high side.

The bearing value provided in the geotechnical investigation report (GI) is higher than we would typically provide within that formation and area. There is no test data contained within the GI report support such a value based on conventional data conversion for typical construction. The value is acceptable for flexible construction.

We are therefore proceeding on the basis that we are accepting the bearing value at face value; however, differential movements may be excessive for some styles of construction and suitable for others. No information has been provided on the structure or performance expectations.
