Contractor Submit Proposed Design to EOR

[Deadblow]

All,
I thought for sure that I recently read a thread on eng-tips that talked about specific codes listing what the contractor is required to submit to the engineer of record. For the life of me, I can't find what I am looking for. I am specifically interested in any code references in the U.S. that state any circumstances where a contractor is required to submit a design to the EOR for approval/rejection. This seems a little backwards to me. Thanks!

I believe it was this one thread507-417906

You're not crazy. That thread appears to have been deleted. Perhaps that EOR on that job frequents eng-tips in addition to being a crummy EOR. Shame, it was an interesting thread. Oh, scratch that, see above.

The takeaway I took from that thread was to look at ACI 132R-14:

https://www.concrete.org/store/productdetail.aspx?ItemID=13214

and that ACI 318-14 Commentary Section R26.1:

This chapter is directed to the licensed design professional responsible for incorporating project requirements into the construction documents. The construction documents should contain all of the necessary design and construction requirements for the contractor to achieve compliance with the Code. It is not intended that the Contractor will need to read and interpret the Code.

From these I've personally concluded that engineering to the code should be done by the engineer of record unless it's specifically delegated to the contractor in the bid documents.

Cant help with specific code references but must comment that I don't see any backward thinking here. It is not beyond the realm of possibility that a contractor would have their own engineers on their payroll.... that would give them a competitive edge when bidding. Indeed at one stage of my career, when acting as construction contractor, not as an engineer, the prime was required to submit a ventilation plan for some proposed underground work. I generated said plan which the prime submitted to the regulatory authority. It was generally acknowledged that that particular authority did not have extensive knowledge regarding underground work, and that was the last anyone heard of the matter. Obviously had there been a major incident, I would have been challenged and probably in trouble.

was the thread I was thinking about. Glad I'm not going crazy.

I worked on projects where large concrete placements (bridge decks and industrial foundations) were shown as monolithic. A note in the contract documents allows the Contractor to propose location of construction joints for the EOR's approval. This is beneficial since the Contractor can sequence work based on his capabilities - not on a predetermined plan.
