Using computer-aided design (CAD) software, piping designers create detailed plans and specifications for piping systems, including material specifications, pipe sizes, routing, and valve locations. Piping designers review project specifications and requirements to ensure that designs meet client expectations and comply with relevant codes and standards. Piping designers conduct field surveys to gather information on existing piping systems and to identify potential design challenges. Piping designers prepare cost estimates for piping systems based on the proposed design, materials, and labor required for installation.
