A Steel Ring

With the concrete ring beam finished and the fabricated steel in the flat we're ready to install the steel ring beam. This is the last major piece of structural work in the project that before we start on the roof. Today we have everyone here: the Polish structural crew, the two Romanian day laborers, Jimmy and myself - 6 people in all.

The steel is first lifted into place by hand and then propped-up using wood posts into the final posistion. Once everything is correct, holes are drilled into the concrete beam and brick where an epoxy adhesive is used to anchor the bolts. As these things go, it's relatively straight forward except for the massive weight of the beams.
