"Typical" Dwg?

The correct drawing will be determined by knowledgeable engineers on the project.

Your questions indicate a lack of knowledge of processes involved in the erection of whatever it is that you have not disclosed to us.

Get some help from an engineer on the project.

If these were for field run piping or cable tray supports, field engineers or designers should have sketched supports in the field, suitable for the conditions, guided by the typical dwgs.

If they were not field run, you should have received design drawings and not the typicals unless they refer to some details.

Dear All

It was a field run conduit piping/cable tray, no detailed drawing all refer to typical drawing, Thanks Al-akhu

It would be a rare thing to have a fully-detailed drawing of a cable tray!

What type of plant are you talking about?

Was this ALL piping and Instrument trays for a new Unit or a small modification?

A "typical" drawing is intended to cover many different applications, not necessarily specific applications. Someone there needs to provide a drawing that is specific to your situation. Fabrication based on a "typical" is never a good idea. Modifications are made that may change what you are fabricating. Always have the drawing certified as being compatible to your project.

We had a job to replace a diesel engine in a ship. We had the drawings of the engine, but couldn't build the foundation until we knew the final engine dimensions. You have the very same situation.

A drawing element marked "TYP" is exactly that: Typical, repetitive, the same.

If the element is "TYP-UNO", then it is exactly that: Typical, Unless Noted Otherwise. Most will be the same, but there will be some that require some sort of special attention.

If a drawing element is identified as General Intent, or General Layout, or something along that line then it is reasonable to assume more specific information is required BEFORE fabrication of individual of components can be done. The party responsible for this information will be as agreed between the parties involved.

I think he is talking about field designed and fabricated supports, probably made from "Unistrut" if it is available. These are used in the power stations here. The "typicals" show various acceptable configurations. The problem in the nuclear power business is that we then had to go and get the information so we could check for performance in an earthquake. That turned out to be a heck of a lot of work.

The typical drawing for cable tray might have five or six trays for a hanging support whereas a floor to ceiling support might have up to twelve.

As I read the OP again, you're probably correct.

I worked on a process building where the unistrut contract dollars was five times that of the doors. These can certainly get very involved and complicated.

you need to raise a request to the deigner/originater of the drawing explaining the site condition and advice to exicute the job or if you are confident you can suggest changes in the drawing depending on the site conditions and request approval of the disigner/originater of typical drawings you need to dacument the incidence this is my personal experience/

Happy Easter. Why draw it in the first place if not done correctly?
