6 CONTROL OF MATERIALS
6-1 General
6-1.01 General
Section 6 includes specifications related to the control of materials . Store materials and samples in a way that preserves the quality and facilitates prompt inspection. Material incorporated into the work must be new . Before the preconstruction conference, submit mate rial source information on a Notice of Materials to be Used form.
6-1.02 Department -Furnished Materials
Request Department -furnished materials except sign panels at least 15 days before their scheduled installation. Request sign panels at least 30 days before their scheduled installation. If the Department furnishes the material:
1.At the job site, unload and store the material
2.At a location other than t he job site, deliver the material to the job site and store it The Engineer orders the return and disposal of surplus Department -furnished material. This returning and disposing of material is change order work. You are responsible for the cost of replacing lost or damaged Department -furnished material. The Department deducts replacement costs. Department -furnished material not used in the work remains the property of the Department.
6-1.03 Local Materials
