Project Overview

This building had a variety of enclosure concerns caused by years of water intrusion.  The owner was looking for a building enclosure consultant to help them address the deteriorated brick façade and leaky roof membrane and turned to OAC for help.

Originally built in 1930, the King County International Airport Terminal is a two-story art deco building.  It has a brick masonry façade and low-slope roof membrane.

OAC first performed a thorough investigation of the existing building enclosure to identify sources of water intrusion and extent of damage.  OAC found corroded lintels, bulging masonry, cracked bricks, deteriorated framing, leaky windows, and a roof membrane that had reached the end of its useful service life.  OAC then developed a comprehensive set of repair drawings and specifications for remediation of the enclosure and oversaw implementation of those repairs during construction.  During the five month construction period, OAC provided construction administration services and worked closely with King County and the general contractor.
