We are new to consulting industry and am wondering how the 30-60-9% submittals are being defined?
I am referring to issuing engineering drawings for customer review.

Thanks

We usually use the revisions PA, PB and PC for issues prior to RFC... Generally PA for internal review/coord and PB for Client review. RFC starts with Rev00... and so forth...

Thanks disk
I am specifically interested to know based on what criteria 30-60-90% submissions are defined?
Level of detail? Or customer defines it?
 
From my experience, percent complete is a mis-guided reference. You may want to look at the terms SD, DD, and CD to get better defined results.

SD = Schematic Design
DD = Design Development
CD = Construction Documents
 
Makes sense.It seems that there is no clear definition between engineers for percentage submittals.
 
We have a company standard that states the level of completeness at different phases.

Sometimes this is overriden by the client who may have specific milestones at different phases.

If you're working as a subcontractor rather than a prime, the prime contractor will likely have their own standard or guidance from the client. You should ask. My company is almost always the prime, so we dictate the standards.
 
A lot depends on the end product. If you're designing a building, the end product is the building. So at 50%, 50% of your members can be designed. But in our industry, water and wastewater treatment, the end product is a treatment facility. So our submittals are treated differently. For instance, the structural needs to be pretty complete at 50%. We can add details, etc., but the size and shape of walls and members need to be pretty well defined and if they need to be changed, you need to make sure it doesn't affect the process. This is so electrical and mechanical can finalize their equipment based on our backgrounds.
I tend to use that time between the 50% and 100% to do final calculations (I use approximations to size thing up to then), package them up, write specifications and stuff that doesn't affect the physical design, i.e. steel beam connections.
 
30 60 90 percent is commonly used in the public sector. there are definitions for these. it varies depending on the agency and type of work.

for instance
30% - preliminary plans, few if any details
60% - complete plans, few details
90% - complete plans, all details completed
100% - complete, revised, checked and accepted final plans


however for private, commercial and industrial work, Ohio Matts referenced method is more common. essentially all work products are issued for information or for review until approved final by the client. then they may be issued for quotation or for construction as rev 0.
 
From a liability point of view, you never want to say that the drawings are "100%". It implies that the drawings are flawless and there could not be any errors or clarifications down the road. Nothing is perfect, no matter how much time you spend on it.
 
So manstrom, what do you call a set of drawings when you are done with them? How does what you call the drawings effect your liability? Liability rests with contracts, industry standard of care, etc.
