PRECAST Concrete column/foundation and beam/column connection details

[adk48ist]

I am designing a reinforced concrete foundation and frame structure to support a two story dwelling in a flood zone; columns are 16' tall to clear the flood elevation;
the contractor wants to use precast columns and beams to save time; I have researched the literature and couldn't find this type of application for precast concrete; Only a German publication showed some details I want to use namely a socket in the pier above the foundation mat where the columns will be inserted; I have also difficulty to design the corner connections where two cantilevered and two continuos beams intersect; these coastal homes usually have 7' wide decks all around the house requiring cantilevered beam support;
I appreciate if anyone familiar to this type of problems help me in design or direct me to related sources. Thanks
Alan

Find out who the local precast manufacturer is in your area and maybe fax them some sketches of your project. They usually have Engineers on staff who would be able to suggest the most practical details.

Typically, the precast manufacturer would design the individual elements and precast to precast connections, your job is typically to provide loads, geometry and also analyze the building for overall stability.
