What Are the Biggest Challenges in Schematic Design for Industrial and Construction Projects? 2

Hi everyone,

I’m studying how engineers and technicians manage the design of electrical schematics, particularly in construction and industrial projects.

• How much time do you spend creating or modifying schematics for these types of projects?
• What are the most common challenges (e.g., time, resources, errors) you face during this process?
• Does this process impact other stages like planning or execution?

If you know of any studies or resources about this topic, please share! Your insights would be a huge help.

Hi Karlour
The number of schematics depends on the type of circuit. For example, DOL, Star/Delta, Soft starters, VSDs, feeders, Incomers, etc., create typical.
The time spent on schematics depends on whether or not you have master schematics. If not, say with a good CAD operator, say 5 hours per schematic.
The process then is to get approval/comments from the client update then send them to the MCC manufacturer, when the installation is complete you may need
As Built's. I hope this helps.
 
I'm not a designer and I've never done the schematics hands-on, but I've worked with Approved For Construction schematics for green field projects as well as As-Built schematics for brown field projects.

Green field schematic is pretty much straight forward. From nothing to something and everything in the schematic will be installed at site. Correction and changes can be done during the construction period and drawing can be updated later on to As-Built.

Brown field is a bit tricky. If the As-Built was lousy, engineer/technician/designer/drafter at work would be pretty much in headache trying to figure out the schematic and doing the correction during the design stage. If this correction was not done properly or limited site input was given during the design stage, everything else would fall apart - from material purchases to planning to execution work - and eventually delaying the completion of the project.

Thank you so much for sharing this information. It really helps me a lot.
