Project OverviewThis survey is part of the Water Research Foundation (WRF) project 5292: Pipeline Infrastructure Replacement Costs Guide, conducted by the Center for Underground Infrastructure Research and Education (CUIRE) at the University of Texas at Arlington.
The purpose of this survey is to collect construction cost data involving open-cut and trenchless technologies. The collected information will be used to develop a planning-level cost estimation guide to support utilities in evaluating alternative pipeline installation, replacement, and renewal methods.
- Estimated completion time: 10–15 minutes per project (faster if bid tabs are available).
- Important instruction: Please provide information only if it is explicitly documented in bid tabs, bid summaries, or project records.
All responses will be aggregated and anonymized. Individual projects or agencies will not be identified in published results.
