I have a three story brick building that requires the replacement of several wood joists that have been damaged over time.  The building was built in 1904 and the walls step in one brick at each floor level until you get to the third floor where the joist no longer sit on a ledge but are in joist pockets which makes replacement difficult without removal of a large portion of the brick above the joist to allow for the new joist to be installed.  Does anyone know of an adjustable metal barjoist / beam that could be used to replace these without all of the brick work?  Or would it be feasable to lap two new joists, lvls, etc...and bolt them together.  The existing building is ~ 25'6" inside of wall to inside of wall with ~ 4" joist pockets in the brick.  The joists are ~ 2-1/2" x 14" rough pine on 16" centers.  The floor will be 2"x4" stripping, perpindicular to the joist on 16" centers, shimmed as required to help level the flooring and will have 3/4" t& g decking and wood flooring above.  The ceiling below will be similar with 1" x 4" stirpping, perpendicular, 16" oc and R-30 fibedrgalss insulation and 5/8" gyp board.  Thanks for your time.
