Constructure was established by President & CEO, Benjamin J. Bohannan, a fifth generation builder.  A true American story that began in the 1930’s, Benjamin’s great great Grandfather, Thomas Bohannan worked in constructing transportation by paving the roadways in Southern California area.  In 1949 the family business was registered with California Secretary of State as Bohannan Paving. 

In 1958, Benjamin’s great Grandfather Iris Bohannan and his two brothers Therin and Olaf continued the family business as T.O.B.I. Transport which stands for “Therin, Olaf & Brother Iris”, they supplied cement, rock and sand. 

Shortly after in 1964, his Grandfather, Glenn Earl Bohannan and his two brothers, continued the family business as Bohannan Bros. Ready Mix Concrete, operating multiple concrete ready mix plants in the greater Los Angles area providing superb service and quality that will be remembered in such buildings as the high rise Federal Building at 11000 Wilshire Blvd., Los Angeles, CA.

In addition to running the concrete ready mix plants, Glenn Earl Bohannan acquired California contractor license classification B-General Contracting in 1975.  At this time in the 1970’s when concrete structures started to become more common for multi-family residential projects, Benjamin’s father, Bryan Earl Bohannan started specializing in the installation of concrete foundations, cast in place walls, columns, retaining walls and suspended decks.


5 generations strong, Constructure operates in capacity as general and concrete contractor in the Southern California region. 

Concrete ready mix supply and placement by 2nd, 3rd and 4th generations.
