Innovation, Efficiency & Productivity

NPL Canada has adopted technology to enhance efficiency, drive measurable results, and promote safety. Examples:

  • Shifted to a new work management system, Field Data Management, or FDM, for better project management, scheduling, materials tracking, and KPI visibility.
  • Prevent damage and manage safety through ULD cross-bore prevention/PICS and dedicated locating that reduces third-party infrastructure strikes.
  • Our pricing model prioritizes predictability through all-inclusive, bundled unit rates, while annual savings initiatives drive productivity gains in projects.
  • We manage costs and performance stays transparent through controls and a shared KPI scorecard that tracks safety, quality, productivity, and customer experience. Quality is also systematized with an ISO-aligned QMS that extends fabrication discipline into the field.

Safety, Quality & Sustainability

The safety of our team members is our top priority. We emphasize a safety-first culture reinforced by task hazard assessments, leadership field engagement, and continuous evaluation. Quality is ensured through our ISO-registered fabrication shop, standardized ITPs, and regular audits. On sustainability, we operate responsibly—reducing fleet and facility emissions toward Centuri’s 25% GHG‑reduction goal by 2030 and supporting programs that lower community emissions, such as RNG interconnections.

Alliance‑Driven Partnerships

Our long‑term model aligns scope, risk, and performance with customer outcomes. We embed with utility teams, share dashboards, and co‑design productivity plans. This approach yields fewer handoffs, facilitates faster decision-making, and fosters continuous improvement. NPL Canada continues to set the standard for best-in-class service and safety within the utility contracting industry, ensuring customer success is always our primary focus.
