Process engineering is the determination of the position and design of the foundations as well as the load specification required for construction analysis .

Typical Building Construction Drawings:

Steel construction plan Formwork plan HVAC ‐ plans Steel grating key plan

Building Design

i. Steel Construction DrawingsShow all details of the steel construction. Does not have to control each single transverse bracing etc. The interfaces are always important.

ii. Formwork PlansFrom which the details of the concrete components are derived. The foundations of the apparatuses, pump sumps, ramps, floor ducts etc. are in the focus.

iii. The HVAC Plans‐Contain data regarding radiators, wall ‐mounted fans, smoke extraction valves, ventilation links, blowers etc.

iv. Steel Grating Key PelanThe individual steel grating elements of which the areas are composed emanate from steel grating key plans. Each steel grating element has to be controlled.

Complex Planning Package

• Fittings concept

• Building design

• Component layout

• Materials concept

• E/MC – conceptShows the most time – consuming and how time ‐ critical the piping planning are.

Documents have to be available before planning

• Piping and instrumentation diagrams

1. Determination of piping classesPiping Classes

Materials qualityDiameter

Component standard

Material and dimensions of

gasketsDimensions of the pipe fittings

Bolt and nut types, dimensions for flange

connections

Wall thickness

Installation lengths and other dimensions

of related fittings

Installation lengths and other dimensions of related

I & C components

flange dimensions

3. Piping alignments

• Piping classes have to be stored in

structured form

• Respective dimension of pipe determined.

•Entails costs already possible

•Each plant platform one or more horizontal

alignments are planned.•Vertical routes able to realize vertical

connection the vertical and diagonal routes.

•The main pipeline distance through the plant

can be covered.

2. Carried out by 3D-CAD system

4. Individual pipe planning

•CAD‐engineers are required where an individual working range will be defined.

•Attention on:

•Blockage

• High temperature pipes

•Pipe stress

• Pipe supports

• Expansion joints

•3D CAD ‐ systems dispose of options which enable the generation of views from any

angle and also possible to zoom into the details.

5. Isometric drawings

2.5D drawing for each individual pipeline.

The individual lengths of the straight pipe section had to be added and each

pipe fitting had to be listed. 10
