The post evolved from the office of the Assistant Surveyor of the Navy (1832–1859)[2] In 1860 the Assistant Surveyor was renamed Chief Constructor the post lasted until 1875 when it was renamed to the Director of Naval Construction.
The chief constructor was originally head of the Royal Corps of Naval Constructors and members of the corps were responsible for the designing and building of warships, whether they were built in the Royal Dockyards (such as Chatham) or contracted out to private industry (such as Armstrong Whitworth).
The latter's officers were responsible for checking that work contracted out by the former was being undertaken correctly.
In designing warships the Director of Naval Construction had to work with the Department of the Engineer-in-Chief, another Admiralty post, which existed from 1847 to 1889.
The French Navy had a similar post, Directeur des Construction Navales.
