Temporary fence for falling debris 1

[larsacious]

I have a situation where a 100 year old building has a brick facade which has severely deteriorated and is imminently hazardous. I need to provide a repair plan to the city. In the interim I would like to recommend a temporary fence to restrict access. Is anyone aware of how car the fence should be offset from the building? The building is 90 feet tall and my concern is that debris from the top floor could land on the public side of the fence.

No answer, but some questions: Are there any projections in the walls, perhaps window sills, or trees which would cause falling objects to be diverted out. Also, what is on the ground to possibly cause bounced objects to be directed out.

Any sidewalks beyond possibly requiring a temporary roof protection to pedestrians.

In NYC, sidewalk sheds are placed for the width of the sidewalk. I attached some info for your use. You can also visit the NYC Buildings Dept. for some other info.

Here is their website; then do a search for sidewalk sheds.

We will put a protective canopy where is a sidewalk exists. There are really no projections from the building before debris to ricochet off of. The building is triangular shaped. There is an alley on one side a parking lot on another in the city street on the other. There is a extremely low volume of pedestrian traffic in the vicinity of the building.

Unfortunately low volume is not no volume... FYI: We have had a recent spat of bricks falling off a building and used two layers of 19.7mm plywood, which showed itself able to withstand the hit in an on-site test the owner insisted upon.
