  4. Liability Assessment: Determining whether defects stem from GC oversight, specialty contractor errors, or design flaws.

Why They Matter:

  • For Building Owners: Forensic experts provide clarity on defect causes, helping you pursue repairs or compensation. Their reports can strengthen negotiations with contractors or insurers.
  • For Insurance Professionals: Experts quantify damages and liability, enabling accurate claim payouts or denials. Their findings can also identify subrogation opportunities (e.g., recovering costs from a responsible contractor).

Average Cost: $200–$500 per hour, with total fees ranging from $5,000 to $100,000 depending on case complexity.

Case Example: A building owner discovers water leaks in a newly constructed office. A forensic expert conducts moisture testing and finds improper flashing installed by a specialty contractor. The expert’s report helps the owner recover repair costs through insurance and pursue liability against the contractor.

 

Best Practices for Building Owners and Insurance Professionals

To maximize value from contractors and forensic experts, consider these strategies:

  1. Vet Contractors Carefully:
  • Check licenses, references, and insurance coverage for both GCs and specialty contractors.
  • Ensure GCs have experience managing your project type; verify specialty contractors’ certifications in their trade.
  1. Use Robust Contracts:
  • Include clear scopes of work, warranties, and dispute resolution clauses.
  • Specify who is liable for defects (GC, specialty contractor, or both).
  1. Engage Forensic Experts Early:
  • Involve experts during defect discovery to preserve evidence and reduce investigation costs.
  • Use their findings to negotiate settlements before escalating to litigation.
  1. Leverage Insurance:
  • Building owners should confirm contractors’ liability coverage to offset defect costs.
  • Insurance professionals should review forensic reports to assess claim validity and coverage limits.
  1. Document Everything:
  • Maintain records of contracts, inspections, and communications to support forensic investigations or claims. 

Conclusion
