What We Do
Services
Whatever stage your data center is in, from commissioning and site readiness through steady-state operations, retrofits and project management, you get one integrated team across the entire lifecycle.
The Integrated Model
One Partner Across the Lifecycle of a Data Center
You need one partner across the entire lifecycle of your data center, not a series of handoffs between vendors. By combining Walbridge's design and construction expertise with L5 Mission Critical's operations capabilities, that's what you get: coverage from commissioning and site readiness through steady-state operations, retrofits and project management, from a team that designed and built the facility and is best positioned to run it. Whether you're a hyperscale, colocation, enterprise, AI/neocloud, or investor-developer client, L5 Mission Critical delivers a flexible, transparent, and community-based approach to operational delivery, from single-site enterprise facilities to gigawatt-scale campuses.
Walbridge
Founded in 1916. Data center construction expertise, national supply chain, and 30+ years of facilities management.
L5 Mission Critical
Commissioning, 24/7 critical operations, retrofits and advisory.
Our Flagship Model
Removing Risk Before It Starts
The gap between design intent, construction execution and day two operations is where most facilities lose reliability and rack up avoidable cost. When Walbridge serves as your construction manager, L5 Mission Critical is there to transition directly into the operations role, carrying forward the same people, documentation and institutional knowledge that supported your build, removing risk before it starts.
Minimized handoff risk between construction and operations
Operational documentation, including as-built drawings, SOPs and MOPs, developed during construction and carried forward as living O&M manuals
Operations coverage from day one, with no gap between substantial completion and steady-state operations
A single point of accountability across design, construction and operations
We built it. We run it. No handoff. Less risk. We don't build a critical operations culture from scratch at every new site. We bring a tested, best-in-class process, and we arrive fluent in how these facilities are designed, built, commissioned and handed over.
Safety is Not Negotiable
L5 Mission Critical's technicians work on live, energized systems inside facilities that cannot go down. That combination demands a safety culture as rigorous as the operations themselves. L5 inherits Walbridge's safety programs and standards, built over more than a century of construction and industrial facilities work, and applies them to every switchgear inspection, generator test, and emergency response procedure.
