Well, let's see. I started out at a consulting environmental firm working on wastewater pumping stations, sanitary sewers and force mains. Then I was lured away by a specialty chemical company that was a client of ours. My primary focus was process piping and instrumentation diagrams, process flow diagrams and block diagrams. I also created a multi-use site pan depicting all underground utilities, individual building layouts of plant process buildings, tank farms, research facilities, offices and warehouses. I drew electrical schematics for the electrical department and structural drawings for the welding department. And then there was all the 3D work I did. Everything from additions to existing buildings, to reactors, storage tanks, loading arms, platforms, stairs, handrails, and various structural steel supports. I'm sure I forgot a few things but that's the bulk of it. I have worked in the fields of civil, structural, highway design, hydro-geologic, industrial and municipal wastewater treatment, electrical and architectural at one time or another.
