Everyone;
Thanks so much for contributing to this discussion! We are getting some applicable topics to discuss, along with some "Good - vs - Bad" Plan submissions.
I would like to post a recently completed Plan Set for your review and opinions. Plan Sheets will be PDFs, with a link to the files (uploaded to my website).
First I need to mask or remove the Client's information, and the Building Department information too.
This Electrical Design-Build Project is a good example of a complex Electrical System, within an older, existing Light Industrial Building.
The most satisfying elements of this particular Project have been:
1: Received compliments from the Plans Examiner (Examiner was very appreciative of contents),
2: Inspections went very smoothly (ease of coordination between Plans -vs- Field Conditions, panel labeling + directories coordinate with Plans, aux. documents available for review),
3: Client is extremely satisfied with complete Design-Build, and has suggested our Services to others,
4: Project was profitable.
The Project was an Industrial T.I. within an existing 12,800 sq. ft. Concrete Tilt-Up, built in 1956.
Existing to remain Services (2):
