What indicates a design issue with a foundation according to geotechnical recommendations?

A design issue with a foundation often arises when the location of the foundation does not align with what was determined during the site investigation. The site investigation is crucial as it assesses the soil conditions, potential hazards, and the overall suitability of the area for the intended construction. If the foundation is placed in a different location from where the site investigation data applies, it may lead to unforeseen problems such as inadequate support, increased risk of settlement, or other geotechnical failures.

This misalignment can undermine the structural integrity of the building and may not account for factors such as soil types, moisture content, and load-bearing capacity that were evaluated during the investigation. Thus, ensuring that the foundation location is consistent with the recommendations from the site investigation is essential for the safety and longevity of the structure.

The other options indicate concerns, but they do not directly signal a design issue linked to the foundation's location as clearly as the chosen option. For instance, retaining structures without drainage provisions may lead to water pressure problems but are not specifically about the foundation’s placement. Similarly, low bearing capacity in footing design is a recognized issue but is not related to the spatial disagreement between the foundation and investigatory findings. Finally, complete foundation plans are necessary for effective construction but do
