Compliance Review

Expert Lead

Dr. Catherine Nguyen, P.E., S.E.

Retaining wall failed peer review forty-eight hours before the county hearing.

The Scenario

Your retaining wall failed peer review forty-eight hours before the county hearing. The reviewing engineer cited inadequate lateral earth pressure calculations and demanded supplemental geotechnical data. The permit window closes in three days. The contractor is mobilized. The developer is on the phone.

Methodology & Outcome

Dr. Nguyen reconstructed the lateral pressure analysis using AASHTO LRFD methodology, incorporated the original geotechnical boring logs with updated seismic coefficients for the site's Zone D classification, and produced a stamped supplemental calculation package that directly addressed each objection raised in the peer review letter.

Verdict

Permit issued within 36 hours. No additional peer review cycle required. Construction mobilized on schedule.

Seismic Certification

Expert Lead

Marcus D. Osei, P.E., LEED AP

Federal seismic retrofit mandate. Six-month window. Twelve buildings. One engineer of record.

The Scenario

The city's housing authority received a federal notice requiring seismic evaluation and retrofit certification for twelve mid-century concrete buildings under ASCE 41 performance objectives. Six months. One engineer of record on staff. No existing structural documentation for nine of the twelve properties.

Methodology & Outcome

Osei deployed a parallel-track documentation protocol — simultaneous field investigation, FEMA P-58 fragility assessments, and retrofit design development across all twelve buildings. Coordinated with the housing authority's single in-house engineer to maintain continuity of record while Fortify produced all stamped deliverables.

Verdict

All twelve certifications delivered in five months. Federal compliance confirmed. Zero notices of deficiency issued across the entire portfolio.

Expert Witness

Expert Lead

Dr. Patricia Yablonsky, P.E., Ph.D.

Catastrophic bridge deck failure. Three parties in litigation. No surviving design documentation.

The Scenario

A section of a county bridge deck collapsed during routine maintenance operations. Three contractors and the county engineering department faced cross-claims totaling $34M. Original design drawings were destroyed in a records office flood. The opposing expert had already submitted a report attributing failure to construction defect.

Methodology & Outcome

Dr. Yablonsky conducted forensic reconstruction of the original design intent using archived permit applications, material test reports, and photogrammetric analysis of the failure debris. Produced a 340-page expert report establishing that the failure mechanism was fatigue-induced delamination consistent with design-life exceedance, not construction defect.

Verdict

All construction-related claims dismissed at summary judgment. County engineering department's liability reduced to 12% of original exposure. Dr. Yablonsky's methodology cited by the court as the evidentiary standard.

"
Fortify's peer review documentation was so thorough that the opposing engineer withdrew their objection before the hearing concluded. We've never seen that happen.
