BTI acts as an expert witness in matters concerning construction defects related to real estate. When construction of a building is completed, the owner may discover various aspects of the construction were improper. This leads to an insurance claim against the contractor. If it cannot be settled, oftentimes it goes to court. BTI steps in as an expert to value the financial impact of defects on the rentability of the property, vacancies that might occur during remediation, as well as increased expenses and possible relocation costs for people, businesses and their assets or belongings.
