1) More interaction between the geotechnical and structural engineer after the structural engineer has reviewed the geotechnical report and started design work. During this conversation, the structural engineer should:
Talk through their understanding of the geotechnical recommendations.
Explain what has been done or will be done concerning site grading, basements, building location, and footing bearing elevations.
Provide the magnitude of the loads on the footings.
Break out the live loads between persistent and transient loads so
that transient live loads do not drive the design.
Explain the range of footing sizes that will be used with the allowable bearing pressure provided in the geotechnical report.
For combined footings or a mat that uses a subgrade modulus, give the geotechnical engineer the elevation and size of the mat/footing, and ask if the subgrade modulus is applicable or needs to be modified.
Request that the geotechnical engineer checks their recommended bearing pressures to see if the bearing pressure can be increased now that they have actual loads and know what soils the footings will bear on.The fact that the geotechnical engineer develops their understanding of the soils by sampling only about 0.000015% of the soil under the site,,THANKS
