Deliverable: • Meeting minutes (MS Word document) Task 2. Sewer System GIS Cleanup The sewer GIS gravity and pressure main layers contain ahnost 17,500 pipe segments. Over 700 islands of pipe exist that are not connected to each other and over 7,600 point structures are disconnected from pipes. Arcadis will make edits to the GIS to eliminate as many isolated pipes and manholes based on proximity of pipe endpoints and engineering judgment. Virtual pipe segments may be created where evidence indicated pipes are connected but nothing is shown. Assumptions in determining how pipes and manholes should connect will be in accordance with the agreements made as part of Task 1. Arcadis will not be reviewing as -built drawings to determine the most appropriate pipe and manhole configuration at this time. These services can be added as future additional services if desired. The Department will provide Arcadis with up to 7,000 reference drawings in electronic format such as PDF or JPEG. Arcadis will create polygon boundaries for each drawing representing the geographic extent they span. Each polygon will include typical title block attributes such as project name, date, page number, page description and a hyperlink to the reference drawing itself. Deliverable: • Personal Geodatabase for the Sanitary, Combined and Storm Sewer networks and reference drawing polygons Task 3. Final Review Meeting Arcadis will hold a project closeout meeting with the Sewers, Engineering and Innovation and Technology Departments. A general overview of the project and goals will be introduced followed by the presentation of GIS summary statistics to compare the data before and after project completion. The meeting will close with a discussion on suggested next steps on progressing the GIS and asset management efforts. Agenda items are as follows: • Project Goals • Sewer GIS review o Before and After • Next steps with GIS and Asset Management Deliverable: • Meeting minutes (MS Word document) Assumptions The following assumptions are made in the creation of this scope of services and the estimated services fee for this project. Assumptions include: Exhibit A, Scope or Basic Engineering Services Pace 2
