Project Overview

In March of 2006, a piece of exterior concrete broke from the façade of a 25-story apartment high rise in the Belltown district of Seattle and fell to the sidewalk below. OAC was hired by the owner to conduct an investigation of the building’s concrete exterior and evaluate the cause for the numerous construction defects, including the extensive cracking and rust bleeding from the post-tensioned (“PT”) tendon pockets.

The investigation revealed extensive construction defects and resulting damage, including cracking and spalling concrete, concrete delaminations, exposed and corroded embedded metals, missing reinforcing, and extensive corrosion of PT tendons.

OAC worked closely with the contractor during the repair effort to resolve on-site issues, review on-going repair conditions, and coordinate tasks between the various team members. The scope of our consulting services included:

> Provide forensic consulting and claim development services for the owner during the construction defect and insurance claims.
> Serve as the owner’s representative during the repair effort.
> Serve as structural engineer and architect of record for the concrete repairs to the exterior façade of the buildings.
> Document the nature and extent of deterioration to concrete elements.

OAC provided extensive litigation support, including multiple deposition testimonies, mediation hearings, and preparation for jury trial in support of the owner’s successful claims against the responsible parties and insurance companies.
