Often the company has over 60 active projects, and has the capability to manage an individual project in excess of $100 million. Even with this growth, Tapani maintains a small-business attitude.

Over the last 35 years, Tapani Inc. has diversified from primarily underground utility work to encompass nine market areas. These areas include: commercial, grading and environmental, industrial, materials, structures, subdivisions, transportation, trucking and, of course, utilities. Depending on the project, Tapani can perform as either the general contractor or subcontractor. With approximately 500 employees, Tapani is prepared to handle complex, large projects or more straightforward, small projects. To ensure that the right tools are ready for any project, a team of mechanics and technicians maintains a fleet of more than 250 pieces of equipment.

Our History

In 1983 on a shoestring budget and a $3,000 loan, Tapani Underground opened for business. Owner Iner Tapani began operations with a backhoe, an old excavator, and a strong work ethic. Tapani Underground installed residential septic systems and performed 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 and steady growth.

During the early years, Iner drove the company backhoe 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.

In 1985 Tapani Underground was the successful low bidder for a Hazel Dell Sewer District job. This was the first public works project for Tapani Underground. Because Iner’s background was in this type of work, these jobs were ideal for the small company. A breakthrough project for the City of Battle Ground was completed near the end of the 1980s, enabling Tapani Underground to position itself for the conservative management of company resources that has been handed down to the second generation of ownership today.

Many of Tapani’s employees who started in the early 1980s remain with the company and share their wisdom and knowledge with the next generation. These employees include Iner and Beverly’s sons and daughters, and even grandchildren. The family-orientated background of Tapani Underground, Inc. is evident in the successive generations of current employees. Tapani’s employees have made the company what it is today!

Over the last several years, the company has grown considerably. This growth has been welcomed and managed. With Tapani’s scope of work expanding into more areas of construction, the family changed the business name from Tapani Underground, Inc., to Tapani Inc. Iner and Beverly have now handed the baton to their sons who are taking Tapani Inc. into the future. As the company’s projects become larger and more complex, Tapani Inc. rises to the challenges and recognizes the endless opportunities these projects bring. With all the employees working together, Tapani has a strong heritage and a promising future…
