A Collaborative Approach to Enhance Decision-Making: GIS & IPL Project
Track: Water, Wastewater, and Stormwater
Authors: Jeffery Coffey, Fernando DeVivo

The Tarrant Regional Water District (TRWD) is one of the largest raw water suppliers in Texas. TRWD maintains its existing pipelines within an ESRI geodatabase to support multiple organizational activities. The Integrated Pipeline (IPL) construction project is a 150 mile regional raw water transmission line ranging in diameter from 84 to 120 inches. Seventeen prime contractors are providing GIS deliverables for pipeline design, survey and mapping, geotechnical, environmental and archaeological information. Aggressive scheduling requires much of this work to be performed concurrently. As GIS deliverable products are accepted and loaded into the project geodatabase by TRWD, it is available to support the 17 contractors via a replication strategy. A cloud-based web mapping application supports decision-making by stakeholders on a daily basis with up-to-date, standardized, authoritative, project-wide information. This paper will illustrate the technical approach and benefits of establishing GIS as a collaborative decision support tool for the IPL project.
