Hi everyone. I'm looking for some advice here. I work in Construction and want to know what are the expectations of a subcontractor in respect to material certification and traceability requirements. The company I work for carries out installations using equipment and materials manufactured and supplied by others (suppliers) We are an electrical contractor and examples of our installations include; 1-Cable ladder rack installation-material is purchased by ourselves from supplier for installation 2-Cable installation-various types and specifications purchased by ourselves based on clients specifications for installation. Any feedback would be greatly appreciated.
