Our commitment is practical and meaningful.
Hoffman Tunnels’ policy is that our business operations implement sustainable practices, and that our project delivery meets our clients’ sustainability aspirations for design, construction and operation.
Sustainability as a way of operating.
We define sustainability as meeting the needs of the present without compromising the ability of future generations to meet theirs. In underground work, that is best accomplished through simultaneous environmental, social and economic improvement — not through a report written at the end.
Underground infrastructure is uniquely long-lived. A tunnel we design today will be carrying water, sewage or passengers for a century. That is the strongest sustainability argument there is: build it once, build it right, and it keeps delivering value without asking for more land, more energy, or more maintenance.

Where sustainability shows up in our work.
- Integrated design and engineering
- Risk management and alternatives analysis
- Envision and LEED project certification
- Tunnel rehabilitation instead of replacement
- Seismic resilience for long service lives
- Structural resilience and asset longevity
Our commitments.
A culture of shared responsibility
Promote a company culture of shared responsibility for sustainability outcomes, and improve the knowledge, awareness and skills of employees in relation to sustainability.
Responsible sourcing and governance
Integrate environmentally and socially responsible sourcing and governance factors into operating and procurement processes, while maintaining economic viability.
Efficient use of resources
Drive the efficient use of resources and continual innovation across our projects and our offices.
Climate resilience
Enhance resilience to climate change, and where possible reduce carbon footprints and emissions on projects where we have influence.
Net positive benefits
Achieve net positive benefits for the environment and community, delivering projects that meet client expectations, provide value for money, and leave positive legacies.
Measured, not asserted
Where desired by clients, efficiently adopt, embed and deliver appropriate industry rating schemes and standards that measure and drive sustainability outcomes.
Sustainability is a part of how we operate our business, and not just part of our projects when our clients request it.Jason Hoffmann, CEO
