The assignment process was partially based on the strategy group <br />recommendations as presented in the previous section. Project identification also considered logical <br />continuous segments of pipe, similar pipe diameters, and geographic proximity. The size of inspection <br />projects were based on the City's request to inspect approximately 30,000 feet per project. <br />To assist in this project identification process, an interactive, GIS -based tool called iCIP was used. <br />Interactive Capital Improvement Planning (iCIP) is a combination of GIS -based tools and processes used <br />by Black & Veatch to supplement and enhance the capital improvement planning process. It includes an <br />interactive and fully customizable GIS -based cost - estimating tool that can assist planning engineers in <br />determining inspect or repair and replacement (R &R) costs. Users can graphically see the results of their <br />decisions and have full control of the factors that support that process. CIP projects can be added, <br />removed or modified graphically; cost calculations are updated automatically. <br />This iCIP tool evolved from Esri's cost estimating template designed with input from the water, <br />wastewater, and storm water user community. It was enhanced by Black & Veatch to provide additional <br />functionality and flexibility. It was also configured specifically for this study to address City- specific <br />considerations such as input file and field names, replacement strategies and cost lookup values. <br />GIS Analysts and Planning Engineers collaborated together using iCIP to identify and refine proposed <br />pipe inspection and replacement projects based on one suggested scenario. In total, ten individual <br />inspection projects were identified to address the City's sewer mains that had no inspection data.
