Pie Spearheads Forensic Evaluation of Historic U.S. Courthouse/ Federal Building

Minneapolis, Minnesota (December 3, 2012) – Pie Consulting & Engineering (Pie) performed a comprehensive forensic evaluation of the landmark U.S. Courthouse/Federal Building in Sioux Falls, South Dakota. The focus of the evaluation was to address ongoing moisture concerns regarding the building’s façade and roof systems.

Pie also provided recommendations for restoration and remediation to address long-term issues with the building that date back to 1946.

Pie’s analysis and testing sequence diagnosed systematic issues with the building’s roof and façade. Pie formulated an estimated budget for the remedial work based on actual bids from local contractors.

“Pie exceeded our expectations on this project by going further than we anticipated in their analysis and recommendations.”– GSA Project Manager.

“The historic nature of the building provided unique challenges during our analysis, not to mention conducting our testing in an occupied and functioning courthouse building.  We were able to successfully diagnose the roof and façade’s long-term issues with minimal impact to the occupants and provide the client with the information they need to move forward.” – Brian Erickson, M.S., P.E., Pie Project Manager.

As part of the forensic evaluation and testing program, Pie utilized depressurization techniques, non-intrusive examination via infrared thermography scans (IRT), and targeted water performance testing utilizing the AAMA 501.2 protocol with the latest equipment and technologies available.
