The Developer will supply the Engineer with a list of plants that will be used for work on site. The plant list will include a list of plant codes as they correlate to IDOT approved mixes. This list must be delivered to the Village Engineer 10 working day prior to asphalt being placed. The testing firm's inspector shall fill out the Village form, and return it to the Village Engineer, along with a copy of field and lab reports. The testing firm is responsible for all field and lab tests, and reports.
