Civil Engineering

Civil engineering that connects site, infrastructure, and building design into one seamless solution.

Mazzetti provides civil engineering planning, design, and consulting services across the Pacific Northwest, supporting healthcare, education, civic, public safety, institutional, commercial, and other complex projects.

Collaboration at Every Stage

We collaborate closely with architects, landscape architects, owners, and contractors to align site, infrastructure, and building systems into one cohesive solution.

Our civil engineers bring decades of experience helping clients navigate complex site and infrastructure challenges. Through proactive collaboration and integrated design, we align civil systems with architectural, landscape, and building requirements to create efficient, resilient, and buildable solutions.

We focus on clear communication, creative problem-solving, and long-term performance to help clients achieve their vision with confidence.

“The staff at Mazzetti are great collaborators in site design and present a wealth of information concerning site characteristics and technical information. We particularly appreciate their deep understanding of urban stormwater and the many ways green infrastructure benefits both projects and the surrounding environment.”

Sustainability and Resiliency

As climate risks continue to evolve, our team helps clients plan for the future with resilient, sustainable site solutions. We evaluate flood risk, implement water reuse and storage strategies, and integrate low-impact development approaches to support long-term operational success.
