1 - Above Ground Piping

- Definition of all piping and valve requirements showing, on engineering flow diagrams, sized, mechanical and material specifications.
- Preparation of utilities flow diagram.
- Preparation of line lists.
- Preparation of plan arrangement drawings and necessary elevations for aboveground piping;
 preparation of isometric detail drawings of aboveground piping 2˝ normal diameter and larger suitable for field – shop fabrication.
- As an alternate to above and at owner’s choice; preparation of a 1:33 scale model to be
 delivered to owner ready for shipment in contractor premises; preparation of isometric detail drawings of all aboveground piping suitable for field shop fabrication.
- Stress analysis of the thermal expansion of the piping system.
