I think this is key. I've began to reject things outright based on this. It causes a lot of problems sometimes.
This is the way. Without pain on the far end of the process, change (more correctly stated, improvement) will never occur.
I will amend, if you all can tolerate it, if I had that "one review only" language I would specifically clarify that drawings received without the contractor's review stamp will NOT be reviewed, but will be rejected and returned. (This is to clarify that you aren't going to "gouge" them for the hour you burn opening the drawings and realizing they aren't stamped by the contractor, and rejecting the submittal formally. You could potentially include a budget for shop drawing review in the contract, i.e. 4 hours, plus the remainder being hourly, because as an engineer you can't turn in a terrible job that's constrained by a set number of hours. You could even explain why (for the benefit of any future "interpreter" of your contract) so your reasoning and the intent is clear. This is to address the wildly varying quality of various submittals, and the need for you, as Engineer of Record, to perform work to the standard of care for similar firms doing similar work in your area. I.e. if there is a massive issue with the drawings, you can't clock out at the 2 hour mark, ethically you are on the hook for the full review.
Another item:
Nobody said a two week review was "standard" but a lot of people expect it much faster than that. Some provision on the drawings that the contractor needs to provide a submittal schedule permitting adequate review time (minimum two weeks due to staffing, sick days, vacations, other projects), and that if the review will take longer they will be notified. Further the drawings need to be submitted in a logical sequence (which isn't defined that well in the contract, oh well).
On delegated steel connection design - having been on practically ALL sides of the fence here, I'll speak. Although nobody asked. ( I suppose being the fabricator would be the side of the fence I've not been on).
From the top:
As EOR -
- a) you are under no particular
requirement to design the connections (I mean globally, apparently there's one state you can't delegate connection designs, and it's not California, it's Louisiana). Your drawings need to be sufficiently complete and provide all the necessary information (loads, load cases, ASD/LRFD, for example) for the connection design engineer to do their work, ideally with work points that are in the correct location (versus some dumb location on a diagonal brace, for example), a work point should be in a sensible location, and as delegated connection design engineer, I've done RFIs to ensure that the EOR knows I'm asking to move the work point to someplace NOT stupid. Be aware the formalization of these "rules" was a reaction to the delegated design on the Kansas City Hyatt, or curiously arrived closely in time after that disaster, which involved unclear delegation of a design, as well as a design change nobody thought about deeply, as well as a "we looked at everything" blanket statement from the EOR on the previous issues with the project in the roof area.....
- b) It needs to be extremely clear you aren't doing the connections and anything shown is either requirements for the connection design to be completed (i.e. minimum 3 bolts for a W16 table or something similar).
- c) Ideally, the client knows connection design is not in the services you provide, but coordination and shop drawing review on the needed delegated design elements to provide a full and complete LFRS will be provided (even if at hourly), ( I suggest reading the Florida rules on delegated design).
- d) actually ACTUALLY read the code of standard practice on the subject. There are quite a few things that are the EOR's responsibility in that document that I see EOR's expecting "me" "we" connection design engineers to provide. I won't name them because I want you to actually read the document.
- e) there's an AISC seminar on transfer forces, this is good to watch if anybody knows where it went or the timeframe for it. Please speak up.
- f) please DON'T be the guy who says "design for 55% of the shear capacity of the section from Table xx." That is so painfully old practice it just wounds my soul to see it on drawings. There are ways to set up RAM to output end reactions you can transcribe (or even export into CAD/REVIT I figure), please explore this.
- g) some connection engineers are really "small firms". Or not firms. Just bear in mind you may have a one person shop pick up the work. Not really any specific advice there, just saying. Some effort on making your drawings less wonky, a bit clearer for the connection designer, would be lovely. Give it some thought, clearer drawings are not a bad thing, across the board.
- h) There are checks out there, particularly for HSS wall thickness, it would be really good for you to know about. When you design a 300' long walkway truss out of HSS for the first time ever, put in some extra effort getting familiar with things as much as you can. Or AVOID something you're not reasonably proficient with.
- i) for cantilever roof framing, or other "beam on top of column" please look at the depth of the elements framing in perpendicularly, I don't want a W16 over the top of a column, going 6" past the column, and some dumb W21 coming into the side that needs to be cut, coped, reinforced, and farted around with when a W21 over the top would just bloody work fine.
As DDE/Specialty engineer -
- a) Changing section depth or member sizes is a no-no.
- b) see d) above
- c) see e) above
- d) don't be afraid to send an RFI, even though you are on the far far side of the project working (most likely) for the fabricator. (i.e. note a) above, and note i) above for the EORs.
As both:
- a) You will quickly realize how bloody hard it is to be a DDE, but your next EOR set of drawings will be far far far better for the next DDE.
Alright gotta run. Sorry this is so short (hah).
