Marquette Interchange Problems
Marquette Interchange Problems
(OP)
Anyone else think it is a little odd that cracks found in the column Monday are already being claimed by HNTB? Is this typical in projects of this magnitude or do they usually get tied up in court?

Perhaps the designer knows it's at fault and figures it's easier to settle now rather than end up on the short end of a lawsuit and risk future business with the DOT.

With today's rush, rush, rush it's imperative that we adapt our checking system to cover the calcs equally as quickly. Another thing to consider is multiple office work and the need to coordinate with everyone when major, major projects are underway.

And let's not put this completely on a pure calculation error. It's possible that the calculations were right and there was an error in the drawing. Of course either way, HNTB is at fault. For some reason, the step of comparing the drawings to the calculations only falls to one set of eyes.
If any of you get an resumes from HNTB with mysterious circumstances of leaving, might want to ask about this.
RE: Marquette Interchange Problems
Another point raised is the old mantra of two sets of eyes on everything before it gets to the door. To that I would add that the extra set of eyes need to be an experienced set not just a set to perform math checks.

RE: Marquette Interchange Problems
In the UK we have Cat0 to Cat3 structures, where Cat0 and Cat1 require and independent check from another engineer in the Design Team, Cat 2 requires a check by a Checking Team (usually another office, i.e. geographical location, of the same company) and Cat3 requires a check by a Checking Team from a different company.
Whilst thorough, this arrangement would seem to fall foul of your requirements re engineers signing off their own designs only?

RE: Marquette Interchange Problems
In the US, depending who you work for, we generally have one engineer/designer do the comps and another more experienced engineer check the work. There is also a overall check that the methodology and comps are done in accordance with expecatations for the industry level of acceptance.
We are now starting to get into second designs/reviews by a separate firm or Peer reviews for structures of significance. It's coming on slowly.
If you work for the Corps of Engineers, the COE has strict rules for who can check designs and who can check drawings resulting from those designs.
I hope this provides some insight to the procedure. Please keep in mind that this may not be the case for each and every project or client. Just my experiences.
