(OP)
In an EPC project, is the piping design basis the first deliverable. If yes, what activities go into making it?

RE: piping design basis
First things I would want to see are 1) some kind of PFD, 2) machinery/equipment footprints, 3) a plot plan.

RE: piping design basis
In piping alone, studies on aspects like geotechnical factors, pipeline access, and land acquisitions are made to establish design basis.
Other studies that may contribute to piping may be scope by other disciplines, such as corrosion control study, material handling, material selection, etc.
RE: piping design basis
From those boundary conditions, the EPC needs to find the seismic zones, archaeology, road/river crossings, and surface disturbance issues.

RE: piping design basis
Pipeline?
Process Plant?
Power Plant?
Pharmaceutical?
On Shore?
Off Shore?
Grass Roots (Green Field)?
Revamp?
Stick Build?
Module Build?
Until we know the answers to these questions it is not possible to give mush help to the OP.
The OP did however specifically ask about the "Piping Design Basis". The Client is normally required to provide the "Piping Design Basis" as a part of 'His' Basis of Design Development (BEDD) Document. This will include the "Code" (ASME B31.1, 3, 4, 8 etc) to be used. The Client is also required to state the "Plant Life" (20, 25, 30 years, etc.) to be used for calculating pipe corrosion allowance and wall thicknesses
Sometimes its possible to do all the right things and still get bad results

I had a process plant in mind when I posted the question. This is response to Pennpiper.
RE: piping design basis
It's basically all the information your client can tell you about the design which pretty much can be taken for granted thereafter, except in unusual circumstances where something might be absolutely necessary to change due to some previously unforseen reason (read that as a potential change order).
