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.
