Started in 1951……..

Scoccolo Brothers Excavating started in 1951 when Armondo Scoccolo and his brother John Scoccolo began providing grading services to the local home builders in the area.  The humble beginnings started out with one dozer and a simple sign on 154th Street in SeaTac providing site work to local builders.  In 1959, Armondo decided to pursue public highway work, working for the local contracting community building the freeways throughout the State of Washington.  Armondo initially installed topsoil on the slopes of the newly construction highways and sprayed the slopes with hydroseed to allow grass to grow on them. For many years, Scoccolo Construction provided high quality topsoil spreading and seeding services up and down the major highway corridors in Washington servicing all of the local highway contractors. His brother, John elected to continue providing grading services to their loyal residential construction customers. Scoccolo Construction Company became incorporated in 1961 and operated until 2001 when the company was renamed SCI Infrastructure, LLC. Armondo retired from the day to day operations in 1998. You can still find him roaming the jobsites when he is not salmon fishing or tending to his garden in the summertime.
