House Foundation issues in AZ: Unveiling Construction Mishaps

Uncovering the Complexity of Foundation Errors in AZ

Foundation problems within a home can stem from various sources, and construction errors stand as a prime culprit in many cases. The Gogte Residence, nestled in the scenic terrain near Pinnacle Peak, Scottsdale, AZ, encountered significant challenges post-construction due to foundational mishaps.

The Gogte Residence and Retaining Wall Predicament

Back in 2004, a sprawling 6000+ square foot luxury dwelling, estimated at a value exceeding $2 million, was erected for Dr. and Mrs. Sudheer Gogte. However, questions emerged concerning the retaining walls' height deviation from the original design and their proximity to the house. These walls, initially planned for a 9' height, were built towering at 15', triggering unforeseen complications. The lack of adjustments to accommodate the increased soil loads compounded the issue. Furthermore, the home's proximity to the wall surpassed the intended distance, significantly amplifying overturning, bending, sliding, and shear stresses.

Despite minimal visible movement, alarm bells rang for the structural integrity of both the wall and the house situated perilously close to the wall's slip plane. Recognizing the gravity of the situation, experts delved into crafting a remediation strategy.

Gervasio & Associates' Remediation Blueprint

Fred Nelson PE from Gervasio & Associates and J. David Deatherage PE from Copper State Engineering spearheaded the remediation plan. Initially contemplating compaction or intrusion grouting, concerns emerged over augmenting lateral pressure on the wall. The proposed strength couldn't be attained solely through grouting efforts. Helical piles emerged as a viable solution to buttress the house's foundation, alleviating the burden on the adjacent soil and wall. However, the rocky soil's formidable nature rendered helical tiebacks ineffective, failing to penetrate the slip plane adequately to restrain the wall.

The intricacies of reversing flexural stresses within the wall's design, originally intended to withstand tensile stresses predominantly on the interior face, posed further challenges for implementing tiebacks effectively.
