Mass timber is emerging as a transformative construction material, meeting the rising demand for sustainable infrastructure and helping public and private sectors achieve their net-zero carbon goals. With its blend of versatility, renewability, and structural efficiency, mass timber is poised to challenge traditional materials like steel and concrete, creating a more eco-friendly construction landscape.
Why Mass Timber?
Mass timber offers numerous advantages, including:
- Sustainability: As a renewable resource, mass timber supports regional economies and contributes to carbon reduction. Every metric ton of wood used in place of steel or concrete avoids an estimated 3.9 metric tons of CO2 emissions.
- Embodied Carbon Reduction: Structural and foundational materials are primary contributors to a building’s embodied carbon footprint. Mass timber buildings are lighter, requiring less carbon-intensive substructures, such as concrete.
- Carbon Storage Vault: Mass timber acts as a carbon storage solution, locking away carbon that would otherwise be released during tree decomposition. Sustainable forestry practices further amplify this benefit by accelerating carbon sequestration in growing forests.
- Construction Efficiency: Prefabricated timber panels streamline on-site construction, reducing labor costs and speeding up timelines.
Swinerton’s Leadership in Mass Timber
Swinerton has become a pioneer in mass timber construction since its first major project in 2016, the First Tech Federal Credit Union Oregon Corporate Campus, which was completed four months faster and at 4% less cost compared to a structural steel alternative. Swinerton has since assembled unparalleled expertise in delivering mass timber projects across sectors such as affordable housing, education, healthcare, and more.
Swinerton’s projects highlight the material’s practical benefits:
- Speed and Cost Savings: Prefabricated timber components reduce construction timelines and on-site labor.
- Environmental Impact: Projects like Northlake Commons in Seattle show significant reductions in carbon emissions, with benefits equivalent to taking 558 cars off the road annually.
