AXIOM Builders Project

Project Overview

Installed civil infrastructure for BC Hydro, including an 18-way duct bank. Overcame unstable soil and utility challenges with strategic stabilization, ensuring a durable, high-quality installation.

Challenge

The BCH 18-way duct bank installation faced significant obstacles due to unstable soil conditions around existing underground utilities. Large nearby services and low compaction around the utilities led to trench failures that repeatedly disrupted excavation. Additionally, the existing utility elevations affected the required conduit grade, forcing deeper excavation than planned, approximately 4m deep with concrete encasement, adding complexity to the installation.

Key Actions

To address these challenges, we adjusted the conduit placement, sweeping the duct bank to a deeper grade level to meet specifications while accommodating the elevations pf existing utilities. To stabilize the loose soil and prevent trench collapse, we implemented knife-edge shoring, creating a safe work zone and controlled excavation. We also carefully managed the concrete encasement process to ensure structural integrity, ensuring the duct bank remained properly supported and protected. These measures provided a stable, precise installation while minimizing disruptions.

Result

By adapting our approach and implementing strategic soil stabilization, we successfully installed the BCH 18-way duct bank in compliance with project specifications. Knife-edge shoring stabilized the excavation, prevented further collapses, and ensured safe working conditions. Our precise execution of the concrete encasement process maintained the duct bank’s structural integrity despite unstable ground. These efforts minimized delays and delivered a high-quality, durable installation.
