I would use my tools to help prep the work area, get forms ready, and place pins. I would measure and cut wood to make barriers for pouring the concrete. I would clean up the area after the concrete pours and make sure that all tools are safely put away and ready for the next job.
I have two certifications in welding, one is for SMAW for vertical, and a GMAW for horizontal.
I also have my 10 hour general industry safety and health certificate.
