Panama Canal work

In 1905, theIsthmian Canal Commissionsought engineers for work on the canal's construction, and since Claybourn was considered one of the best for such work, he accepted a position as superintendent of all floating equipment of the U.S. government property on the Canal Zone. He oversaw a staff of about 500 men and was paid $3,000 per year.

Claybourn designed and constructed the drydock shops atCristóbal, Colón,and rebuilt the "Old French" dock to accommodate larger vessels.
