Timothy Wieneke serves as an appraisal umpire and expert witness in property insurance matters. Engagements are accepted from courts, insurers, policyholders, and counsel.
More than twenty five years in property and casualty claims, forensic estimating, and building consulting. Work has included field adjustment, large loss handling, scope and estimate review, causation analysis, and reconstruction of historical scopes and costs as of past dates of loss. Claims experience exceeds $20 million. Appraisal panel service has included matters with initial demands above $25 million.
Prior engagements have included a substantial volume of insurer and defense work. That history reflects how the practice developed rather than a position on the merits of any given claim. The same methods are applied in all engagements: independent review of the record, inspection where warranted, and reasoned written analysis.
