ABSTRACT
This chapter aims to devise the most economical plant layout while providing an operable plant that can be readily maintained. Working with process, mechanical, and civil /structural engineers, the plant layout engineers develop the initial planning studies. Layout starts based upon the P&IDs, the site topography, access and other information, specifications, preliminary process and mechanical data for major equipment items and additional requirements from the owner. The piping engineering discipline is the focal point of plant layout and plot plan development. Job hours included in plant layout and piping design account for approximately 40% of home office engineering time and some 30% of construction field labor of most industrial process plants. Piping's role is especially crucial during the early phase of project development. The chapter highlights seven piping discipline activities such as design approach, staffing, piping materials, equipment orientation, supplier drawings, pipespool design and pipespool fabrication.
