The tapered strips volition provide a level surface against which they could place the new steel beam.

Like well-nigh structural repair projects, this one involved more preconstruction piece of work and site prep work than actual repair work on site. We started several months before any site work was performed with an inspection of a heavy timber roof beam that supported a section of roof in an old warehouse, which had been converted years before into a condominium apartment complex. This axle was taking a significant amount of the roof's load, and information technology appeared from the ground that the timber was rotating. A closer inspection revealed a full beam failure. A cadre sample was ordered, which confirmed that the interior of the heavy timber had rotted abroad.

The leaks that initially caused this rot had been taken intendance of long ago, and past this time, the interior rot was fallow. The beam wouldn't deteriorate farther if it stayed dry, but it was structurally unsound. In an effort to save the homeowners association money, the applied science team weighed leaving the timber in place against the much more involved job of removing and replacing it. For the final design, the engineering squad and homeowners association opted to install a new steel beam directly under the existing timber to carry the roof load. This replacement beam would besides be designed to pick up the loads on all the purlins that tied into the beam. The purlins themselves were perfectly sound, only nosotros could no longer rely on their connection to the timber beam.
