Question on Standards re Reinforced Concrete Buildings

[140Airpower]

There is a 15 story building going up between two much older buildings in Manhattan. It is steel reinforced concrete. In a 6" space between a new building wall and an old building it can be seen that the new concrete is extremely rough and uneven with up to 4 foot lengths of rebar protruding out all over. Is this allowed under NY state standards?

This sounds like extremely poor construction and from a corrosion point could have some serious problems is close to ocean spray/mist...

Can you post some photographs?

Agree with dik. Sounds unacceptable by any standard.

Good morning 140Airpower,

Does the adjacent building next door seem to be a part of the overall project or possibly being demolished? While not the best practice, I have seen "bend-out" dowels used for future expansion ties. The surface roughness you see might be the remnants of an expanded mesh back form for a shotcrete wall. It is possible to collapse and retrieve a wall form in a very narrow space but one-sided approaches are used too.

regards,
Michel

I'll try to get some pictures. The adjacent buildings aren't going anywhere soon so there won't be a chance to finish the wall. The roughness might be understandable, but the large amount of exposed rebar is hard to understand. It is vertical, looking like it belongs inside, not horizontal as if anchorages for something in the future.
