Investigations

Experience

We have experience with several types of investigations, working with real estate agents, Insurance Companies, and developers, and serving as an expert witness.

Investigation Types

  • Residential Pre-purchase Inspections - A preliminary visual examination made at the request of Buyer or Seller or the recommendation of the home inspector to determine if the apparent structural damage observed is significant and what an estimate of repair costs are.
  • Structural Condition Assessment - A visual examination made to assess the condition of the structure: help the Owner plan a Renovation, Addition, or Repair; evaluate Construction Defects; investigation of a Structural Failure, such as a roof collapse from excess snow load or tree impact.
  • Seismic Vulnerability Assessment - A comprehensive Engineering Study to evaluate susceptibility of structural systems to potential damage from seismic shaking.
  • Post Earthquake Damage Assessment - We are certified under ATC 20 to assist the Building Department after an earthquake.
