Tapani is a family owned business, building the critical infrastructure and buildings that support our communities across the Pacific Northwest.
Since 1983, our team has grown from a single-family crew to a team of over 500 employees with offices in both Washington and Oregon. Our work has diversified from primarily underground utility work to five different areas including Civil Site Development, Buildings, Transportation, Utility Infrastructure and Environmental. With every project we do, we are passionate about building what matters while improving the lives of our employees, clients and trade partners.
In 1983, Tapani Underground opened for business. Founder Iner Tapani began operations with a backhoe, an old excavator, and a strong work ethic. Tapani Underground started small, installing residential septic systems and performing any other work that could be done during the bleak economic climate of the mid-1980s. Through several years of dawn till dusk work, the company experienced slow but steady growth. During the early years, Iner drove the backhoe down the road to the next job site followed by his wife, Beverly, in the family car with the hazard lights flashing. With this continued teamwork, Iner and Beverly expanded their two-person operation into a multi-million dollar business. Over the years, the company has grown considerably. With the company’s scope of work expanding into more areas of construction, the family changed the business name from Tapani Underground, Inc., to Tapani Inc. in 2012. In 2015, Iner and Beverly retired and passed the responsibilities of running Tapani to their sons, with Leigh as president. As Tapani continues to grow and expand, the humble beginnings and core values we were founded on are not forgotten.
