GTR Review Checklist for Spread Footings


F. Structure Foundations - Spread Footings

 (Pgs. 7-1 to 7-17)

In addition to the basic information listed in Section A, is the following information provided in the project foundation report?

  1. *Are spread footing recommended for foundation support? If not, are reasons for not using them discussed?

    If spread footing supports are recommended, are conclusions and recommendations given for the following:

        (Yes   /   No   /   Unknown or N/A)

  2. *Is recommended bottom of footing elevation and reason for recommendation (e.g., based on frost depth, estimated scour depth, or depth to competent bearing material) given?

        (Yes   /   No   /   Unknown or N/A)

  3. *Is recommended allowable soil or rock bearing pressure given?

        (Yes   /   No   /   Unknown or N/A)

  4. *Is estimated footing settlement and time given?

        (Yes   /   No   /   Unknown or N/A)

  5. *Where spread footings are recommended to support abutments placed in the bridge end fill, are special gradation and compaction requirements provided for select end fill and backwall drainage material (Pgs. 6-1 to 6-4)

        (Yes   /   No   /   Unknown or N/A)

Construction Considerations
  1. Have the materials been adequately described on which the footing is to be placed so the project inspector can verify that material is as expected?

        (Yes   /   No   /   Unknown or N/A)

  2. Have excavation requirements been included for safe slopes in open excavations, need for sheeting or shoring, etc.?

        (Yes   /   No   /   Unknown or N/A)

  3. Has fluctuation of the groundwater table been addressed?

        (Yes   /   No   /   Unknown or N/A)

*A response other than (yes) or (N/A) for any of these checklist questions is cause to contact the appropriate geotechnical engineer for a clarification and/or to discuss the project.
