[edit] Summary

Here is another code violation waiting to happen. The drywall is required to have a fire-resistance rating. The plumber is there before the drywaller. He follows a seriously flawed firestop specification by the mechanical engineer and hangs a steel sleeve in place, thus creating a round hole for the pipe (penetrant) to traverse. This is utterly wrong. The sleeve is but another penetrant. In this case, it is also a great heatsink, which will carry more heat through to the unexposed side. Instead, a properly prepared Section 07840 Firestop specification should have been used, to regulate the forming of openings to enable proper bounding, whereby one speciality firestop sub-contractor seals all through-penetrations and building joints in one sub-contract to the general contractor. As it is, this opening shown here is very difficult to fix, especially the tight spaces between the drywall and the sleeve itself.
