3 Topics Discussed GIS Intro Requirements How it works The process The deliverables Benefits Carlton, MN application and rehab project Summary Conclusions Question and answer

4 Introduction What is the Benefit? Coordination between an Owner, consulting firm, and a CCTV inspection contractor. Allows Owners to add value to the standard CCTV inspection process by using GIS technology. Expedites the assessment of sewer inspection data and provides multiple deliverable formats.

5 Requirements GIS mapping platform. ESRI GIS format (GDB, SHP, SDE). Reasonable level of accuracy. Location of mains, manholes, lift stations. CCTV inspection database PACP format. GPS coordinates of manholes (field collection).

6 Makes a GIS database talk to a CCTV inspection database to condense the data into a map format. How Does it Work?

7 How Does it Work? GIS Data Mimics the Real World Real world measurements and lengths. Real world flow or inspection directions. Real world locations of defects/ maintenance issues/laterals.

8 What Information Can Be Captured? Mainline and lateral locations. Mainline and lateral condition and defects/maintenance issues. Manhole locations in conjunction with CCTV work. Overall condition rating of pipe sections (MH to MH).

9 Elimination of this

10 For New Mapping

11 The Deliverables Standard inspection reports and video. Mainline defect/maintenance issue location information. Lateral location information. Lateral defect location information. Condition rating for main line and laterals. Updated system maps.

34 Summary The integration of GIS technology adds substantial value to the CCTV process. Process delivers an efficient and complete snapshot of the sewer system with overall ratings of pipelines in an easy to read format. Map format is ideal for presentations to councils and committees. People can understand a picture! Fast and efficient.

35 Summary Reduces review time for staff and/or consultants = cost and time savings. Lateral mapping aids in risk reduction of Digger s Hotline Locates. Owners can build and update their sewer system maps in conjunction with pipeline inspections.

36 Summary CMOM Compliance Tool. Information can easily be converted into bidding documents for future pipeline maintenance and rehab projects as evidenced by the Carlton project. Flexible hard copy maps to mobile applications. Asset management.

37 Conclusion Integrating GIS technology into CCTV inspections provides value and efficiencies. Provides accurate and efficient system and defect mapping and condition assessment. Expedites the review/decision making process. Allows for continuous system map updates and asset management. Aids in bidding documents for pipe rehabilitation projects.
