D1.1 & D1.5 and Pile UT

Date 01-17-2010 17:00

Dear All,
The bridge is designed accordance with D1.5; there are many pile have heavy wall thickness and produced by rolling and welding girth and longidintual seam. Pile manufacturer says that UT inspection should be accordance with D1.5. However, it is not a code for tubular structure. However, D1.1 Include the tubular structure and its inspection topics. Manufacturer says the piles are not tubular structure because piles have to allow to reach to inner side of its structure? I want to know that is the pile tubular or not and which code should we use for UT inspection?

Thanks for your time

When in doubt, kick it back to the design engineer. That what he gets the big bucks for. Those are calls that are beyond the inspector's responsibility.

In the U.S. you almost always see D1.1 applied to everything up to and including the pier caps and D1.5 above the caps.
Engineering has taken that stance since time immorial for reasons known only to them.

I agree that it's a call to be made by the EOR, anything else is a disaster waiting to happen. If you scour the contract documents you might find the answer.

It was inappropriate for the EOR to spec D1.5 for the piles, but you'd have to convince them of that...
