Big Sky Custom Builder — Snow-Load Roof Failure
Mid-winter snow load on a partially completed Yellowstone Club custom exceeded design assumptions during a 3-day storm cycle. Temporary bracing at a vaulted-ceiling section deformed; the ridge sagged 4 inches and required structural re-engineering. Total damage and rework: $186,000. The builder's risk policy demanded engineered temporary bracing documentation as a coverage trigger.
Pulled the builder's risk policy and the engineered bracing requirements. The contractor had documentation but it hadn't been collected centrally. Coordinated the documentation submission to the carrier and walked the contractor through subrogation against the framing sub.
Builder's risk paid net of deductible after documentation submission. Subrogation against the framing sub recovered $80,000. Going forward, the contractor maintains a centralized engineered bracing log. Montana mountain construction without that documentation is one storm cycle away from a coverage decline.
