Tapani has expanded significantly in recent years, moving beyond its underground construction roots into the building sector while completing numerous projects throughout Clark County, Washington.

Despite growing to more than 700 employees, the company has maintained its family-oriented culture that has characterized the organization since its founding.

Tapani has made notable progress in Alternative Delivery, pursuing and securing projects requiring innovative approaches beyond traditional methods. This has established the company as a trusted partner for complex challenges, positioning it as an industry leader.

The company recently expanded its geographic footprint by opening a new office in Idaho. With five offices across three states, Tapani can better serve clients while delivering high-quality infrastructure projects.

Environmental stewardship remains central to Tapani’s operations. The company implements environmentally conscious practices, collaborating with various entities to build and restore infrastructure including hatcheries, fish ladders and dams. Specific measures include using biodegradable oils, thoroughly cleaning equipment to prevent spreading invasive species, and making necessary changes to protect natural ecosystems.
Tapani has developed essential community infrastructure including parks, schools, water systems and office spaces that support local economic growth. The company focuses on providing infrastructure that enhances quality of life and strengthens communities for future generations.
