5C is currently supplying one to five material hauling trucks to a local concrete company. We are picking up sand and rock for the concrete company and delivering it to their plant for use in their concrete mixes. We began providing the services 5/15/17 and have done so most everyday since. I would say there hasn't been more than 2-3 days break in the work at a time. Does that have an impact on the "start date" of the project? If we are eligible to file a Mechanics Lien is it too late to submit the 20 day _preliminary notice? I understand that it would only grant us back through the beginning of November. Thank you!
