Spare Engineering can face several of your CAD drawing services, and in this sense, the below listing shall not be considered as exhaustive, but rather to act as a starting framework, and as example reference.

Essentially, such drawing activities shall be considered as a "passive" electronic format drawings preparation (Autocad™ as typical working platform), originated from other similar document (obviously modified and revised as required, on the basis of mark-up issued by the Client), or "recovered" from an old paper format (fairly common occurrence in case of revamping), but still accompanied by comments and directives about contents and template of document, all originated from the Client. 

Like to say that normally, such drawing services activities will provide only the transposition in the drawing, as indicated in the draft and as per the Client's comments,and therefore there is no "added value".

In any case, with the exception of drawing activities indicated for the Process Department (for these, our commitment may be extended "only" to verification of proper instrumentation representation, suitable instrument tagging, and control and block logics representation), for the other drawing activities shown for the instrumentation and electrical departments, we may also cover the design and the context verification for such documents, taking them in charge in full.

Process Enginering Department
- P&ID, originated from similar electronic documents, with Client's mark-up; - P&ID, originated from paper format documents, with Client's mark-up; - emergency block diagram (LSD  / PSD / ESD);
- material balance document;	- etc.
Electrical Engineering Department
- single line diagrams; - functional diagrams; - logic diagrams; - light layouts;	- cable and cable try layout; - earth system layout; - tracing system isometric sketches; - etc.
Instrumentation Engineering Department
- primary hook up; - secondary electrical hook up; - loop diagrams definition; - actuated valves commands logic; - fusible plag layout; - logic diagrams and sequential flow;	- junction boxes rack layout; - instruments layout; - junction boxes layout; - pneumatic distribution layout; - wiring diagrams; - etc.

Obviously, we remain at your complete disposal for any information you may need, or for the combined evaluation of further not listed CAD drawing services, also to be related to other departments  (e.g. bi-dimensional piping, sketches to accomplish the "Piping Class" document details, etc.).
