Forensic Construction Consulting: Uncovering the Truth
Standard inspections often fail to identify the true scope of a property defect. Our forensic consulting team goes beneath the surface—literally—to provide a comprehensive understanding of structural failures and environmental contamination.
Destructive Testing & Hidden Cause Identification
Many construction defects are “latent,” hiding behind stucco, siding, or flooring. JLS specializes in destructive testing, a process where we strategically remove layers of a structure to pinpoint the exact source of a problem. This is critical for:
- Water Intrusion Analysis: Identifying failed flashing, improper window installations, or defective waterproofing membranes.
- Mold Origin Determination: Proving whether a mold bloom was caused by a sudden pipe burst or a long-term maintenance failure.
- Causation Analysis: Differentiating between damage caused by a specific “peril” (like a storm or fire) and pre-existing wear and tear or construction defects.
Cost of Repair (COR) & Estimating Services
Accurate quantification of damages is essential for fair settlement or judgment. We provide detailed Cost of Repair (COR) reports that break down every necessary line item for restoration. Because we are an active General Contractor, our estimates are based on real-world labor and material costs, not theoretical models.
Specialized Case Types
Our forensic team is equipped to handle a diverse range of complex property claims:
- Mold & Environmental Exposure: As a premier expert witness in mold remediation, we evaluate the adequacy of past remediation efforts, identify cross-contamination, and verify adherence to IICRC S520 standards.
- Water Intrusion & Building Envelope Failures: We investigate stucco cracks, balcony leaks, and roof failures to determine if they stem from design errors, poor craftsmanship, or natural disasters.
- Fire & Smoke Damage: Beyond visible charring, we assess the forensic impact of soot and smoke on structural integrity and indoor air quality.
- Construction Defect Litigation: We represent both plaintiffs and defendants in cases involving multi-family developments, commercial facilities, and high-end residential estates.
Comprehensive Legal Support
We understand that a consultant’s job doesn’t end with a report. We partner with legal teams throughout the entire lifecycle of a case:
- Onsite Forensic Inspections: Thorough documentation with high-resolution photography, moisture mapping, and material sampling.
- Attorney Consultations: Reviewing case facts and providing preliminary opinions to help counsel determine the viability of a claim.
- Review of Industry Standards: Benchmarking the subject property against California and Nevada building codes and industry best practices.
