Providing Full Service Heavy Civil Marine Construction Since 1983

探花精选系列 HISTORY

In 1983, Kent Cochran and Konrad Schweiger started a legacy of success in marine construction with the founding of Advanced American Diving. Over more than 3 decades, 探花精选系列 has built on that legacy to become one of the most successful marine construction companies in the Northwest. Today, 探花精选系列 continues to grow and take on exciting projects that showcase our expertise in heavy civil construction, diving and marine survey, industrial and engineering services.


  • Advanced American Diving Service, Inc. (AADS) was founded by Konrad Schweiger and Kent Cochran as a commercial diving business in Oregon City, Oregon. 


  • AADS purchased the M. Cutter Company (MCC) located in Vancouver, Washington. MCC provided quality emergency machinery and equipment repairs for both industrial and marine clients including paper and steel mills and grain elevators in the Northwest  since 1986.
  • Kent Cochran, founder of AADS retires from the company.
  • Forrest Schweiger, son of AADS founder Konrad Schweiger died in a construction accident at age 26.
    The Forrest L. Schweiger memorial scholarship was founded by AADS in his memory. 


  • AADS founder Konrad Schweiger passed away unexpectedly on April 11, 2002 at age 56. Konrad Schweiger had  worked as a sheet metal worker, welder and diver since 1966.  In 1980, Konrad and Bill Shires began All Coast Commercial Divers in Coos Bay, where Konrad was decorated with the Carnegie Medal of Honor and the Marine Medal of Honor. In 1983 he returned to Portland and founded AADS with Kent Cochran. In 2002, the Forrest L. Schweiger Scholarship was renamed to the Schweiger Memorial Scholarship fund to honor both Forrest and Konrad Schweiger.


  • AADS celebrated its 20th anniversary and was recognized by its public and private sector clients for excellent performance in commercial diving and marine construction.  Parent company Advanced American Construction Inc. was created as an umbrella for AADS and MCC.


  • AADS and MCC formally merged and adopted the name Advanced American Construction, Inc. (探花精选系列) to more accurately reflect the company’s broad range of marine construction, diving and industrial services.
