The job of keeping the exterior of Salesforce Tower clean is made possible with help from a pair of innovative tools.

In Portland, construction workers plugged away this week on the Knight Cancer Institute’s new building. Draped in scaffolding on two sides, the 320,000-square-foot building is the latest piece in a decade-long investment in the South Waterfront neighborhood.

The construction market has been growing steadily for the past six years and Benson Industries, Inc. was listed 84th largest specialty contractor in the United States.

Four buildings, from the United States, Australia, the Netherlands and the United Arab Emirates, have been named the best tall buildings in the world for 2014 by the Council on Tall Buildings and Urban Habitat (CTBUH).

The Seattle Art Museum contracted Benson to install an art installation on the building’s facade. The work is by Doug Aitken, and is called Mirror. It consists of large LED panels and light strips. Benson engineered and installed the original for the Seattle Art Museum in 2006.

Benson Industries was selected as the 2013 Honored Citizen by The Architecture Foundation of Oregon and they created this video for the presentation ceremony. Watch the full video here.

7 Bryant Park, New York, NY is a 30 Story office building with a “bow tie” feature that faces Bryant Park in midtown Manhattan designed by Pei Cobb Freed and Partners.

The LA Courthouse in Los Angeles, CA is a 200+ foot tall pleated glass cube designed by Skidmore, Owings & Merrill LLP.

Benson Industries helped replace the failing facade of 1730 Pennsylvania Avenue in 2009. The all-glass facade gave the building a new face, increased building performance, and daylight access.
