Spear Reaming
Spear Reaming
(OP)
Contractor sent out the steel pre-construction agenda and under Field Modifications to Structural Steel it has the topic "Pre-approval for spear reaming to fair connection misalignment".
It is my understanding that this means that when they have bolt holes that do not align to the point where they can't install the bolts, then they will wedge a "spear" into the holes and then work them until they reach an alignment where the bolt will fit.
Can you please confirm my understanding of this practice and provide any guidance on why this should or should not be allowed.

RE: Spear Reaming
I strongly suspect that no one has EVER brought up the definition before, that it is a "boilerplate" rubber-stamped "thingie" inserted to allow them to finangle and widget and wiggle and drill and wedge and sledge-hammer and bend everything to allow something to fit through anything once so at least one thing can fit anywhere through once. As soon as the first drift pin gets through by hoof, crook, or guess and golly-gee-whiz, the rest are rammed through as the crane and rigging crew jiggle the other steel beams to get the holes to match 'enough".
Press them on this issue, and they will get a new respect for the one company that actually read their package.
