PIPING ISOMETRIC DRAWINGS

(*)The size of piping isometric drawings is site–specific and will be specified by the Owner’s Engineer. Generally, they are 11” X 17” or 18” X 24”.
The piping isometric north arrow shall be oriented as specified by the CAD Supervisor.
(*)The isometric drawing shall include a bill of materials located on the right hand side of the drawing or on a separate drawing as specified by the Owner’s Engineer. The associated line

number must be referenced in the drawing title block for all bill of materials drawings.

(*)The bill of materials shall include the following items as a minimum. Additional items shall be approved by the Owner’s Engineer.
Itemized description of piping and components.
Quantity of each component.
Size (appropriate dimension) of each component.
Weight or schedule of flange or pipe, respectively.
Rating, bore and face or end type of flange or fitting component, respectively.
IPE Code Number for each component (see EP 5–2–3).

Identify “shop” and “field” fabricated piping.
The isometric drawing shall include the Owner’s standard title block (see EP 2–3–2).
(*)Provisions shall be made to include supplemental information in addition to the standard title block. Supplemental information shall include the following items. Additional items shall be approved by the Owner’s Engineer.
