The assembly shows a hollow structural section column welded to a steel base plate, which is anchored to a concrete foundation using threaded anchor bolts with double nuts and washers. A grout layer of specified thickness is placed beneath the base plate, and leveling is achieved using either leveling nuts or shim stacks. A plan view of the square base plate demonstrates the bolt hole configuration and plate dimensions relative to the HSS column profile.
