Page 8 of 8 M-17 A - Route Survey Requirements (Continued) New Drawing AS -BUILT RECORD DRAWINGS GIS Mapping Staff maintains a County -wide base map of all water, wastewater, reclaimed water and RIO concentrate mains, appurtenances and associated infrastructure. When a Utility project is completed, IRCDUS receives As -Built Record Drawings from the Contractors' Surveyor in AutoCad, electronic format files. County GIS Mapping Staff converts the lines of the newly constructed utility infrastructure into shape files, which are imported to the County -wide base map. To help streamline the process, the Contractors' Surveyor, charged with providing As -Built Record Drawings to IRCDUS, will create AutoCad layers formatted with specific named layers. The purpose is to streamline the conversion process. All water related infrastructure to be in one layer named Water. All wastewater infrastructure to be in one layer named Sewer, etc. ROUTE SURVEYS - AUTOCAD LAYER STATES The Department of Utility Services receives AutoCad, electronic format files, of Route Surveys from consultants that are used in design of water and wastewater projects. Generally, the larger the survey file, the more cumbersome the design task becomes. IRCDUS has received AutoCad files with an excessive number of drawing layers where many of the layers are unused. Staff is asked to delete the unused layers and slowly sift through the layers to "clean the drawing". At one time the County received (5) five copies of all surveys and As -built record drawings. For paper copies, the number of AutoCad layers used was irrelevant. As we transition even more toward using electronic format drawings for design and base mapping, style and format becomes much more important. Drawing M-17, Route Survey Requirements, is specific to the survey requirements. When the County request Surveys from a Consultant, the Consultants shall use drawing M-17 as a guide and deliver route surveys to IRCDUS utilizing only layers specific to that survey SPECIFICATION SECTION — REVISIONS The following Sections have been revised.
