As the height of a building increases, the most dominant wind forces on a building change from those on the roof to those on the walls of the building. This concept has been the basis of the dual set of provisions in the ASCE 7 Standard and building codes since the original wind tunnel studies were completed in the 1960’s and 1970’s.

January 25, 2019 | Seattle, WA |You could say that Jim Harris—or Lou Billy—took the scenic route in his forty-one-year career—not as many straight lines in the trajectory that you might expect from a structural engineer. But it has a solidity to it, built on years of dedication, commitment and relationships.
“Let’s get lunch,” says Lou. “Do you mind a walk?” I grab my coat and we stroll through downtown Seattle. 

Please join PCS Structural Solutions in welcoming their newest staff members: Brian Krieger, Connor Moore, Jared Plank, Samantha Taylor, Spencer Sharma, and Valerie Hendel.
Brian Krieger joins PCS as a Project Engineer in the Tacoma office. Brian brings over 4 years of industry experience working on flood resilience and transit projects. His current work includes Olympia High School Addition and Modernization in Olympia, Washington and South Bend Elementary School in South Bend, Washington.

In the same year that the Beatles played the Memorial Coliseum in Portland, Oregon, when gas was thirty-one cents a gallon, and an attempt to move the Cleveland Indians to Seattle fell apart, Hansen, Adams, & Chalker Engineers was established in Tacoma, Washington.

Natrona County High School in Casper, Wyoming, stood relatively untouched for nearly 100 years, until the four-story, concrete-and-masonry structure finally underwent an over-$100 million renovation and addition, completed late last year.
All told, the facility encompasses over 300,000 square feet of renovated and new building area. Construction was completed in six phases over five years, with design beginning in late 2011.
