Instead of the bolt on truss system, we used a tube and pocket design. In this approach we cut two openings at each floor level, brought columns against the wall, slid tubes through the pockets and welded them to the columns. By using the tube and pocket design we were able to create a quality floor support system at the tie-in, and the portions of the task that would have interfered with Mouser operations were completed over a single weekend - without interrupting the client's employees.
