Portland's newly constructed airport terminal is making waves in the construction industry with its innovative use of local tribal timber. The use of cross-laminated timber (CLT), also known as "mass-timber," sets a new standard for sustainable building materials. The terminal's remarkable features include inherent fire resistance, reduced carbon footprint, and an aesthetically pleasing design.

The construction industry is increasingly turning to CLT due to its durability and flexibility. Unlike plywood, CLT is made by pressing long boards together cross-ways with glue and high temperatures, resulting in a strong and versatile material.

The new terminal's massive roof, covering an area of 9 acres, is made entirely of CLT sourced from within a 300-mile radius of Portland. The Douglas fir, hemlock, and southern yellow pine used in the construction were obtained from Oregon landowners and Tribal nations. Each board used in the skylights and beams has a unique story, with the Yakama Nation and Coquille Indian Tribe contributing to the project.

Portland's airport terminal not only showcases the potential of the American mass timber market but also highlights the environmental benefits of using sustainable materials. Mass timber is a low-carbon building solution, unlike concrete, which is a major emitter of greenhouse gases. Additionally, the carbon absorbed by the trees used in mass timber construction remains sequestered, contributing to the reduction of the global carbon cycle.

This landmark project is expected to inspire other cities across the country to explore the possibilities of using local and sustainable materials for their construction projects. By embracing tribal timber and sustainable practices, Portland's new airport is leading the way towards a greener and more eco-friendly future for the aviation industry.
