Who Determines Bolt Length? 1

[swearingen]

Generally, when specifying high strength bolts for structures, we give the type and diameter but not the length. The contractor is left to decide what his length should be, allowing him to leverage cost reductions using large-quantity ordering. The contractor is better positioned than the engineer to determine this savings.

Our client is being asked by the contractor to provide bolt lengths. Is this common?


-5^2 = -25 ;-)

Even if the engineer provides the detailing they are not providing the shop and/or erection drawings, which is what section 4.5 says. If you as the EOR are not providing the shop and/or erection drawings you would not need to provide the lengths even if you did detailing.
