Tower Building
|
Seattle, Washington
Client: Vance Corporation Dates of Service: 1998 Project Summary: This historic high-rise office building was experiencing long-term, significant leakage at its upper-level windows, its brick veneer and terra-cotta claddings were degrading, and concrete walls were spalling.
PL:BECS Services: PL:BECS provided an evaluation of the building’s exterior envelope systems, analyzed the sources of widespread leakage, and advised the owner concerning appropriate corrective measures.
The PL:BECS evaluation revealed inadequate densities and corrosion of brick veneer anchors, corrosion of masonry support lintels, corrosive spalling of cast-in-place concrete walls, absence of window flashings, seismic cracking in structural concrete walls, degradation of the brick veneer and terra-cotta claddings, and similar problems. To limit costs, the evaluation’s findings were presented to the owner verbally, in combination with photographs, and through demonstration of typical problem areas via a tour of the building. |
