Why the U.S. Army Corps of Engineers is Building with Mass Timber
The U.S. mass timber industry is rapidly growing as sustainability becomes a priority for both governmental organizations and corporations.
A policy by the U.S. Army Corps of Engineers (USACE) mandates the consideration of mass timber for all vertical construction projects, signaling a shift toward reducing the environmental impact of construction materials like concrete and steel.
The policy encourages engineers to “consider at least one option where mass timber is a substantial structural component” early in the design process, according to the Engineering News-Record.
Environmental sustainability
Mass timber is a renewable resource. It requires less energy to produce than concrete or steel, helping to reduce a building’s overall carbon footprint.
Strength and durability
Despite being lightweight, mass timber’s strength and durability is comparable to steel and concrete, making it suitable for various types of buildings.
Faster construction
Prefabricated mass timber components streamline construction, reducing build time, labor costs and waste. A 2015 Army project using cross-laminated timber (CLT) was completed 20% faster and with 44% fewer labor hours compared to traditional methods.
Fire resistance
Mass timber is surprisingly fire-resistant. The outer layer chars in a fire, protecting the internal structure and maintaining integrity for longer. At Bell, we also offer an optional treatment with Class A fire retardant, Flame Stop.
Aesthetic appeal
The natural look of wood enhances the design of interior spaces, creating a warm, nature-inspired atmosphere that boosts well-being and productivity.
Energy efficiency
Wood’s natural insulating properties improve energy efficiency, leading to lower heating and cooling costs and a more comfortable indoor environment.
Acoustic performance
Wood enhances a room’s acoustics by minimizing echo and reverberation, creating a more enjoyable listening experience.
Design flexibility
Mass timber is one of the most versatile building materials. It’s ideal for almost any architectural style and projects ranging from residential homes to large commercial structures.
Health and well-being
Recent studies show natural materials like wood positively impact air quality and the mental and physical health of building occupants.
Seismic performance
The flexibility and lightweight nature of mass timber allow it to perform well in seismic events, making it a good building material for earthquake-prone areas.
