Rampart Pipeline

BT successfully completed the first two of three phases of a critical infrastructure project for the City of Aurora between November 2021 and March 2024, with the final phase scheduled for Winter 2025. BT slip lined a 48” steel liner pipe into an existing 54” PCCP waterline that runs through the densely developed Denver Tech Center. This line is a vital component of Aurora’s water system, connecting the Aurora Rampart Reservoir to the city. All work must occur during low-demand winter months when outages are permissible. 

Project Highlights

  • Multiple municipalities
  • Multiple phases
  • Complicated scheduling

Challenges

  • Limited seasonal shutdown windows and tight completion deadlines
  • Confined space entry was required throughout, which heightened safety risks and necessitated continuous airflow management
  • Narrow tolerance between the liner and host pipe

Solutions & Approach

  • Created innovative solutions and detailed planning
  • Utilized custom-engineered carts explicitly designed for this slip-lining project, allowing for precise and efficient installation of the steel liner inside the existing pipe
  • Careful execution and a commitment to safety and quality
