Typically, these markings are done when Roux staff members are not physically present on-site. <br /> To enhance understanding/accuracy, it is advisable for staff to be present during the 811 process or engage <br /> in conversations with locators, both public and private, while on-site. Additionally, utility marks must adhere <br /> to the proper standards outlined in the Uniform Color Code. <br /> Common Abbreviations(Source:Common Ground Alliance) <br /> Facility Identifier Underground Construction Infrastructure Materials <br /> Descriptions <br /> CH Chemical C Conduit ABS Acrylonitrile - Butadiene- Styrene <br /> E Electric CDR Corridor ACP Asbestos Cement Pipe <br /> FO Fiber Optic D Distribution Facility CL Cast Iron <br /> G Gas DB Direct Buried CMC Cement Mortar Coated <br /> LPG Liquefied Petroleum DE Dead End CML Cement Mortar Lined <br /> PP Petroleum Products JT Joint Trench CPP Corrugated Plastic Pipe <br /> RR Railroad Signal HP High Pressure CMP Corrugated Metal Pipe <br /> S Sewer HH Hand Hole CU Copper <br /> SD Storm Drain MH Manhole CWD Creosote Wood Duct <br /> SS Storm Sewer PB Pull Box HDPE High Density Polyethylene <br /> SL Street Lighting R Radius MTD Multiple Tile Duct <br /> STM Steam STR Structure (vaults,junction PLA Plastic (conduit or pipe) <br /> inlets, lift station) <br /> SP Slurry System T Transmission Facility RCB Reinforced Concrete Box <br /> TEL Telephone RCP Reinforced Concrete Pipe <br /> TS ITraffic Signal RF lReinforced Fiberglass <br /> TV Television SCCP Steel Cylinder Concrete Pipe <br /> W Water STL Steel <br /> W Reclaimed Water VCP Vitrified Clay Pipe <br /> "Purple" <br /> FNN_0C_1rYCO/W <br /> NO TELCO <br /> NO GASCOIGIDIT Work Area <br /> NO ELECO Delineation <br /> 03/2025 Corporate Health and Safety Management Program I ROUX 5 <br />
