During my 45 years as a commercial construction superintendent, I have built a number of canopies, similar to the one that "fell". First, in order to even consider building such an overhang, structural engineers have to submit design and structural drawings along with calculations that allow for wind, snow and water loads, earthquake problems and other such unlikely events (like being run into by a huge 5th wheel trailer).
With approved plans from the local building department, the contractor is then expected to follow them to the letter, (that was my job) with building inspectors checking many phases of progress. If any deviations are noted, a stop-notice is filed and the job is red tagged if the violations are not corrected.
Just looking at the pictures, I see that there was a pipe column on the right side of the canopy, that was bolted down, hopefully to a concrete footing, in leiu on a thin concrete slab. (I can see no anchor bolts protruding from the base plate of the column, were there weak bolts or nuts?) The top of the column shows no visible connection to any structural members within the structure, just some black-iron framing members used to support the plastered ceiling. The masonry enclosing the steel pipe column is just gingerbread to hide the column and match the existing construction in the main building.
Someone messed up, big time on this one. A law suit is surely going to follow, and Mister Deep-Pockets, ie, the Architect, the Structural Engr., The Contractor along with his Superintendent will all probably be listed in the law suit. I could see no structural connection to the existing bank building, and I have a feeling that they are going to hang the blame on the Structural Engineer who goofed on his design. Just my 2 cents.
