I understand that. Cut my teeth in residential as my Father was a home builder then I became a home builder for 15 or so years. Probably built several hundred homes and townhomes during that part of my career.
Always wanted to do civil work so after the depression of '09, started a new company focused on doing excavation, demolition and similar work. In '11 formed a company and started doing whatever I could do to establish my name in a new segment of the market - commercial construction.
i took on a dollar store project this year overall dint pay out well for me I made money but still but the ground I was at was swamp and it just wasn't a great first project
If one knows the game commercial/industrial work can be very lucrative. There is mountains of paperwork, huge insurance policies and safety training to have but it's rewarded with $$. A good set of plans and specs is vital to the success of a project and the bottom line.
