Carpenters Tower

Project Overview

After a piece of exterior concrete separated from the façade of a 25-story apartment high-rise in Seattle and fell to the sidewalk below, OAC was hired to conduct an investigation of the building’s concrete exterior and evaluate the cause of extensive cracking and rust bleeding.

The investigation revealed extensive construction defects and resulting damage. During the repair effort, OAC resolved onsite issues, reviewed ongoing repair conditions, and coordinated tasks. We provided forensic consulting and claim development services during the construction defect and insurance claims phase, represented the owner during repairs, provided structural engineering and architect –of-record services for concrete repairs and extensive litigation support. Through our efforts, the owner was successful and won their case against responsible parties and the insurance companies.
