Erickson Structural Company Picnic

By | News | No Comments

On August 15, 2013 Erickson Structural employees, and their families, got together at Fairgrounds Park in Ridgefield, WA for the annual company picnic.  This is always a fun event that allows us to get to know each other’s families, play games and, of course, eat some really yummy treats!

Yale Elementary School Gymnasium

By | Structural Renovations of Existing Buildings | No Comments

Erickson Structural was retained to design the structural modifications and seismic upgrades to the existing Yale Elementary School gymnasium in Ariel, Washington.  The Woodland School District requested that the seismic upgrade be designed to meet an enhanced performance objective, namely Life Safety for the BSE-2 design earthquake, according to ASCE 41 standards.  Non-seismic structural modifications were designed to satisfy the applicable portions of the 2009 International Building Code (IBC) with Washington amendments.  The existing roof structure has been replaced with a new roof structure designed to support a snow load that exceeds the code minimum, based upon local reports of past snow accumulation for the area.

This project has successfully been completed and this refreshing upgrade to this existing building  will provide years of enjoyment and use to the children of Yale Elementary and the community.

Rothenberger v. Kent School District

By | Structural Forensic Investigations | No Comments

Erickson Structural was retained in the case of Rothenberger v Kent School District to structurally evaluate the wall of windows in the Kentridge High School cafeteria where the plaintiff was injured, allegedly due to defects in the window glass.  Erickson Structural was asked to determine the in-situ structural strength of the glass in windows that was representative of the window glass involved in the plaintiff’s accident.

Erickson Structural developed and oversaw a testing protocol that recreated the manner in which the plaintiff testified he broke one of these windows.  The window glass strength tests utilized a custom-fabricated steel frame that held a load cell with a prosthetic hand attached to it.  The prosthetic hand was advanced towards and against selected windows, at the same location where the plaintiff testified his hand contacted the subject window glass, until the glass in the windows broke.  The force and associated strain required to break each window was digitally documented.

Prior to commencement of the window glass strength testing at the school, Erickson Structural, utilized standard engineering principles to mathematically quantify the theoretical load capacity of the windows involved in the incident, then employed forensic testing to physically replicate the prior calculations.  The results of the forensic window testing were in general agreement with Erickson Structural’s prior engineering calculations, lending further credibility to the forensic window testing procedure and results.

The results of Erickson Structural’s forensic investigation facilitated a settlement of this matter between the parties.
