Here are two photos of a highrise building that is being constructed using pre-fab construction methods. As you can see, the A & C sides are placed, then the floor slab of the upper floor, which is held up by struts until the side walls are added. In the second picture you can see the side walls arriving with the windows installed and everything. Mid-rise and high-rise buildings are being constructed like this all across the country. This changes how we have to think about these buildings. They may not be as compartmentalized as we are used to and the collapse hazards change now. The building is now, essentially, a giant Jenga puzzle, perfectly balanced. It may not stand up to collapses caused by spalling or a crew breaching a wall, floor, or ceiling like a typical Type 1 building that we are used to. Has anyone had a fire in a building constructed like this yet? What smoke and fire spread issues did you encounter? Was the void spaces and cut outs for the building services properly fire stopped?
Note: the camera angle may be misleading, what may appear to some to be a finished first or second floor of the building under construction is actually a completely separate building located quite a distance away.
Below you can see the side walls arriving, two to a trailer to finish enclosing the building.
Many contractors use the pre-fab construction method to finish a building project. It is less messy than the traditional method and it is simpler to clean after the construction is finished. Of course, a professional construction clean up Maumee should clean the newly built building to be certain that the job is done correctly.
