Watch this building fall down under the heavy snow:
It seems that every severe winter Mossien Associates are called to assist with a partial building collapse, highly deflecting (sagging) beams, bulging walls or some other snow and temperature related problem.
The collapse shown in this video is of a light gauge metal building. We have designed several of these buildings and they have a very low sloped pitch with standing seam metal roof and use prefabricated structural members.
They are very economical to erect, about in the range of $85 per square foot. But, they can be damaged or fail when stressed with a couple feet of very heavy wet snow. The building codes require commercial architects to add certain roof live loads and wall wind loads, but remember, codes are for a minimum level of safety.
We tend to overdesign in our Western New York climate for added safety. It may cost a little more but look at the costs added to this business!
Business interruption insurance can help but not replace lost customers and employees.
